The title "commerce and industry" is the name which the writer prefers should be given to the subject which is usually taught in secondary schools under the name of "commercial geography." Probably this title was adopted because during the eighteenth century in European schools patronized by the trading classes there was taught, under the name of "traders' geography," a body of information concerning things "useful for a merchant to know" with special reference to trade and transportation. This name, "commercial geography," is not a fortunate one, since the information imparted, while it has a geographical bearing, is not chiefly geographical as its title suggests. Professor Lyde, recognized as one of the great authorities on geography, says: There is no essential difference whatever in the end in view, the principles involved, or the method to be used, between teaching geography from the economic point of view and teaching it from any other point of view .... And it is, therefore, a cause for much regret that the teaching of the science from this point of view ever came to be called the teaching of "commercial geography." I think that no other single word ever did so much harm to the teaching of any subject, for it made writers write and-still worse-teachers teach as though all the importance lay, not in the end proposed, the underlying principles, or the practical method, but in the commercial products-which are always incidental and often absolutely immaterial.'

The chapter inquires into the spirit of the democratic revolution. Instead of focusing on its nature—the symbolic shift from the sovereign king to the sovereign people—it concentrates on its principle: How could the monarchical principle of honor, and its designation of society into a hierarchy of social classes give way to a revolutionary quest for equality? Assuming that part of the answer lies in the overwhelming experience of uncertainty that accompanies the democratic revolution, the chapter distinguishes between three meanings of uncertainty—cosmic, human, and political—and reconstructs the democratic meaning of emancipation. The aim is to show that a democratic political lifeform tames uncertainty by sharing and dividing it equally. It emancipates us from a state of self-incurred tutelage.

This paper describes the verification of the structural integrity for the gates of the flood spillway of the hydroelectric dam Malpaso (Chiapas, Mexico), which height was increased about 1 m because they had to operate close to the extraordinary maximum water level. The increment on the water level of the reservoir was originated because of the weather conditions that had recently caused the sliding of a mass that had obstructed the river, downstream of the dam. Works had to be done on the obstruction zone, and the Malpaso dam had to stop its energy production. The gates were instrumented with strain gage rosettes, an analysis of the theoretical model subjected to those conditions was generated, and their performance was evaluated. The analyses showed that the performance of the gates do not represent a risk for the service of the structures.

A propos de Gilbert Herdt : Sambia sexual culture: essays from the field (University of Chicago Press, 1999), l'A. discute l'analyse de Herdt des pratiques homosexuelles sambia d'un point de vue historique comparatif. Il suggere que si Herdt situe ses resultats melanesiens dans un contexte elargi, son travail pionnier en dit beaucoup plus - que ce que Herdt revendique dans sa recherche - sur les differentes manieres dont la relation entre genre et erotisme a evolue dans le temps. L'analyse de Herdt ainsi que les propres recherches de l'A. sur la Thailande interrogent les consequences de la separation categorielle occidentale entre genre et sexualite et notamment : est-ce que l'engagement contre l'occultation et la marginalisation de l'homosexualite en Occident entraine necessairement de situer la sexualite au centre de l'analyse, et cela est-il la meilleure strategie pour l'etude comparative de l'ethnographie et de l'histoire des cultures erotiques au niveau global ?

OBJETIVO: analisar a atencao em anticoncepcao recebida por mulheres durante a hospitalizacao por abortamento e suas praticas contraceptivas, no mes subsequente a esse episodio. METODO: estudo longitudinal com mulheres hospitalizadas por abortamento, em uma maternidade publica da cidade de Sao Paulo. Foram feitas entrevistas face a face (n=170) e, apos um mes, por contato telefonico (n=147) entre maio e dezembro de 2011. RESULTADOS: as orientacoes em anticoncepcao e a alta hospitalar com metodo anticonceptivo prescrito foram referidas por proporcao reduzida de mulheres. Houve tendencia de significância estatistica para a prescricao de metodo anticonceptivo, ajustado pela idade, na alta hospitalar e o seu uso no mes subsequente. A maioria das mulheres teve relacoes sexuais (69,4%) com uso de metodo anticoncepcional (82,4%), mas sem orientacao de profissional de saude (63,1%). CONCLUSAO: apesar da atencao em anticoncepcao pos-abortamento estar aquem das diretrizes estabelecidas pelas politicas publicas, as mulheres demonstraram disponibilidade para usar metodos anticonceptivos.

Wireless sensor networks (WSNs) is composed of a large number of tiny sensors. These energy-constrained sensors are deployed in a variety of environments to collect data such as temperature, humidity, and light intensity. Therefore, how to suppress the impact of environmental noise on the collection accuracy and extend the lifetime of WSNs is one of the prominent issues. This article proposes an optimized dictionary updating learning-based compressed data collection algorithm (ODUL-CDC) to suppress the impact of environmental noise on the accuracy of WSNs data collection and extend the life cycle of WSNs. The proposed algorithm uses the dictionary learning method to obtain a sparse dictionary by learning from the training data. The collection error caused by environmental noise is positively correlated with the degree of self-coherence of the sparse dictionary. Therefore, the self-coherence penalty term is introduced during the dictionary updating process, which can reduce the over-fitting of the training data in the dictionary learning process. Moreover, the self-coherence penalty term endows the learned sparse dictionary with a low-self-coherence structure. Experimental and simulation results show that, as compared with discrete cosine transform(DCT), K-SVD and IDL learning-based data collection methods, the proposed algorithm exhibits the highest increase in recovery accuracy of 3.2% in the signal-to-noise ratio (SNR) range of 30–50 dB, the sampling ratio range of 25%-40% and the sparsity range from 3 to 30. Furthermore, the energy consumption is significantly less than that of the compared methods, which helps improve the network lifetime.

Recent research has established that households absorb from professional forecasters as they form their inflation expectations. Professionals forecasts are transmitted, or absorbed, throughout the population slowly but eventually. This provides the microfoundations for sticky information expectations. Using a unique survey-based dataset for the UK that distinguishes between professional and non-professional forecasts and where the former is further categorize by occupations, the present paper attempts to identify the professional forecaster. The paper also considers whether absorption rates take place heterogeneously amongst the absorbing agents. We identify active and passive absorbers amongst the agents and they are distinguished by their respective absorption rates. The present analyses also consider whether these absorption rates are non-linear.

In this work, a sensorless control scheme was designed for permanent magnet synchronous motors based on a sampled model. The discrete-time model was obtained using the Symplectic Euler method. Taking such model along with voltage and current measurements, an observer is designed for rotor position and velocity estimation. Then, the rotor velocity is forced to track a desired reference signal by means of a discrete-time quasi-sliding mode technique.

Within the BGM (Brace, Gatarek and Musiela, 1997) interest rate model, this article prices Asian interest rate options via the Vorst (1992) approximation approach. To consist with market practice, we modify the setting of the average rate in Longstaff (1995) by employing the arithmetic average of (market-observable) LIBOR rates. The LIBOR rates are specified directly rather than transformed from the unobservable short rates. Moreover, the parameters in our pricing formula can be easily calibrated from market data. The pricing formula is shown to be sufficiently accurate as compared with Monte Carlo simulation. The calibration procedure and the practical examples are also presented.

In seeking to expand an understanding of consumption, this study assesses the relationship between status consumption and conspicuous consumption. Theoretically, the relationship between status consumption and conspicuous consumption is problematic and, therefore, the main focus of this paper examines the theoretical and empirical separation of consumers' status consumption and conspicuous consumption. Data were gathered via a survey of individuals aged between 18 and 25. The findings indicate that status consumption and conspicuous consumption are distinct constructs. Differences in status consumption tendencies between males and females were not found; however, in relation to conspicuous consumption gender differences were found. Status consumption was affected by self-monitoring and interpersonal influences, but conspicuous consumption was affected only by interpersonal influences. The brands examined also clearly differed in terms of status and conspicuous consumption perceptions. Copyright © 2004 Henry Stewart Publications Ltd.

Previous research has shown that job insecurity is linked to a range of performance outcomes, but the number of studies exploring this relationship is still limited and the results are somewhat mixed. The first aim of this study was to meta-analytically investigate how job insecurity is related to task performance, contextual performance, counterproductive work behavior, creativity, and safety compliance. The second aim was to test two method-related factors (cross-sectional vs. longitudinal associations and self- vs. supervisor-ratings of performance) and two macro-level indicators of social protection (social welfare regime and union density) as moderators of these associations. The results show that job insecurity was generally associated with impaired employee performance. These findings were generally similar both cross-sectionally and longitudinally and irrespective of rater. Overall, the associations between job insecurity and negative performance outcomes were weaker in welfare regimes characterized by strong social protection, whereas the results concerning union density produced mixed results. A majority of the findings confirmed the negative associations between job insecurity and types of employee performance, but future research is needed to elaborate on the effects of temporal aspects, differences between ratings sources, and further indicators of social protection in different cultural settings in the context of job insecurity.

A new analytical method referred to as “Derivatization-Electron Probe X-Ray Microanalysis (XMA)” has been developed to determine the distribution of 0.1% order functional groups in polymers with micron level lateral resolution. Depth profiles of the functional groups in the polyethylene (PE) degraded by the outdoor-exposure were determined using this method. The results suggested that the PE degrades from the surface and the backface due to the oxidation during the outdoor-exposure, and the rain extracts the oxidation products generated near the surface. Also, it was confirmed that the load by water was indispensable for the accelerated weathering test. The sensitivity of the derivatization-XMA was approximately 2–6 times higher than that of micro-IR. Through this research, the utility of the derivatization-XMA method for studying the degradation mechanism and characterizing polymers was confirmed.

A reproducible test system requiring small amounts of test compound was developed for evaluating antiviral and interferon-inducing activity. In the antiviral experiments, KB cells were grown in disposable polystyrene microplates covered with a standard domestic plastic wrap. Viruses used in the system were types 1 and 2 herpes simplex virus, vaccinia virus, type 3 adenovirus, myxoma virus, pseudorabies virus, type 3 parainfluenza virus, types 1A and 13 rhinovirus, vesicular stomatitis virus, coxsackievirus B, and type 2 poliovirus. Inhibition of viral cytopathogenic effect was the primary criterion of evaluation of antiviral activity. Reduction in cell and supernatant fluid virus titers was used as a secondary means of evaluation. The microplate system was adaptable for determining prophylactic, therapeutic, and inactivating effects against viruses. Mouse L-929 cells were used for the interferon induction studies, with vesicular stomatitis virus utilized as the indicator of interferon activity. Known active compounds evaluated in this microplate system had activity similar to that seen in macro in vitro systems.

A Revised and more numerically accurate version of the Direct Batch Evaluation by constrained Optimization Algorithm (RDBEOA) of orthonormal eigenvectors of the DFT matrix F is (RDBEOA) of orthonormal eigenvectors of the DFT matrix F is from the fact that it performs the singular value decomposition (SVD) of a matrix whose elements have almost half the range of values of the elements of the matrix to which the SVD is applied in the previous Direct Batch Evaluation by constrained Optimization Algorithm (DBEOA). Having more accurate Hermite-Gaussian-like (HGL) orthonormal eigenvectors of matrix F is a main requirement in the development of the discrete fractional Fourier transform (DFRFT).

A 6‐year‐old boy suffering from epilepsy was referred for fundus evaluation from the department of pediatrics. The child was the third offspring, born by uneventful full‐term vaginal delivery with normal developmental milestones. He had multiple nontender pigmented papules over his nose and cheeks [Fig. 1a]. Visual acuity was 6/6 in both eyes (OU). On ocular examination, OU anterior segment was normal with reactive pupils. Fundus evaluation of the left eye (OS) revealed multiple slightly elevated greyish white retinal lesions measuring about 4.5 mm × 3 mm and 1.5 mm × 1.5 mm in size with distinct margins in the nasal periphery [Fig. 1b]. Right eye fundus was unremarkable.

This lightning talk describes our current effort to implement and use Discord - a new tool to facilitate group work that an instructor can use to moderate the level of group participation of students. By utilizing Discord's features to their full extent, an instructor can actively moderate the group's interactions, keep track of who is/isn't participating, and even send messages to student groups. Instructors have the ability to create a Discord server, which acts as a virtual classroom, and then use the server to store student accounts, sort students into groups, and enable group chatrooms. Within these chatrooms, the instructor can observe for language, how well teams are keeping on task, and most importantly, level of participation. This tool keeps students accountable for how often they collaborate with the team by using a chat log with timestamps that the instructor can audit. A goal of implementing Discord is to introduce a user-friendly tool that instructors can use to moderate group interactions and hold students accountable for their level of participation within their groups. A second goal of this project is to utilize the ability to programmatically access the communications in an effort to automate content and sentiment analysis to determine team effectiveness.

The paper suggests an approach to developing the veneer sorting model based on fuzzy logic. Wide implementation and development of automated rotary-cut veneer sorting system is inhibited by the difficulties when creating analytical models. The reasonability of using fuzzy logics for veneer sorting is due to the large number of factors having significant impact, and rich expertise of engineers. The model was built and tested for two main factors: the number of healthy and deformed knots. Further studies shall be aimed at increasing the number of factors considered, collecting statistic and expert information in order to build membership functions for linguistic variables, and forming the base of rules bringing relation between the input and output variables.

In an earlier study using maize seedlings grown from kernels inoculated with Fusarium verticillioides, fumonisin B(1) (FB(1)) was preferentially accumulated in leaf tissue compared to FB(2) and FB(3). The present study tested whether maize seedlings preferentially translocate FB(1) when plants are watered with FB(1) and/or FB(2), without the fungus present. The results show that neither FB(1) nor FB(2) was translocated when administered in the watering solution, and although both FB(1) and FB(2) were taken up by the roots, the accumulation of FB(2) in roots was significantly less than expected, indicating that FB(1) was preferentially accumulated. In addition, there was clear evidence of ceramide synthase inhibition in the roots and sphingoid base and sphingoid base 1-phosphates accumulated in leaf tissue presumably due to translocation from the roots. These findings suggest that the fungus-plant interaction is necessary for FB(1) translocation in maize seedlings infected with F. verticillioides.

basalt across the uplifted Cretacous and earlier strata, the counties of Antrim and Londonderry include high igneous plateaux, cut by deep valleys in which the underlying rocks are seen. The landscapes close around Belfast reveal the structure of the country in perfection. In the west of Ireland, dykes of basalt, running characteristically north-west and south-east, are so frequent as to show that the plateaux once prevailed from Down to the Atlantic coast. Sporadic eruptions occurred even in the Galway area, and basalt fragments prevail on the sea-floor between Ireland and Rockall. The granite of the Mourne Mountains was intruded in the same period of unrest, and the pinnacles and rocky walls of the group are a sign of youth when compared with the older granite areas in Ireland. The existing surface of northern Ireland was determined by the falling-in and dislocation of the volcanic country that once spread northward to the Faroe Isles. Lough Neagh thus lies in a shallow basin formed during this epoch of subsidence and decay. The long sea-inlets of the north and west, including Belfast Lough and the ' rias' and ' fjords ' of Connemara and Kerry, originated about the same time; but Ireland, now cut off from the lost continent on the north-west, became joined on to the growing continent of Cainozoic Europe. The spread of ice in glacial times is marked by numerous hills of gravel and eskers, especially in the central plain, where they form green ridges rising from the bogland and the prairie. The oscillations of level between the glacial epoch and the present day finally left Ireland cut off from Scotland, Wales, and England, with which her fundamental geological structure so obviously connects her. It is interesting to note that the most prominent features of her landscapes at the present day depend on structures impressed upon the area far back in Palaeozoic times.

One of the strong candidates for biodiesel is Crude Coconut Oil (CCO) but its high viscosity cannot be applied directly without treatment. Therefore, nanocarbon is added to reduce the viscosity of CCO. Nanocarbon is a natural material with semiconductor properties, a good heat conductor, and can attract other molecules. By adding nanocarbon, it is expected to reduce the viscosity of CCO. This study aimed to determine the combustion characteristics of droplets on CCO by adding nanocarbon by 1% and 5%. The method used was a true experiment with droplets, which dripped on the thermocouple with activation energy from the heater. The results showed that CCO burned 0.933s with a droplet diameter of 4.307mm, droplet diameter of 5.472 mm. By adding 5% nanocarbon to CCO, the CCO burned faster, more reactive, and the ignition was shorter than the pure CCO and 1% CCO.

The ideology of the information society has transformed the performance of academic duties within higher education through the permeation of information and communication technologies (ICTs) into all aspects of the university. These technologies provide a common ground upon which teaching, research, and administration fuse; but how have such arrangements affected the quality of academic work? This ideology functions through values, hierarchies, rewards and punishments, and surveillance that influence routine work. Using a critical orientation, this paper examines the transformation of the quality of the intellectual products and work processes of higher education in a North American context. It examines how the educational technology industry fosters a type of control over academic workers, inhibiting the individual laborer’s pursuit of educational quality. Grounded in Foucault’s concept of “disciplinary power” and in Freire’s notions of critical consciousness, it suggests a community-centered approach toward building knowledge capital in higher education.

Abstract Aberrant internal carotid artery (ICA) in the middle ear is a rare, dangerous vascular anomaly and conservative follow-up was usually adopted in most reported cases. Here we report the case of an 8-year-old girl with symptoms of objective pulsatile tinnitus and conductive hearing loss in the right ear. Otoscopic examination, computed tomography, and conventional angiography were performed. An aberrant ICA combined with a ‘third mobile window’ was suspected preoperatively and confirmed at exploratory surgery of the middle ear. The aberrant ICA was treated, and the pulsatile tinnitus disappeared and hearing recovered after the surgery. This case suggests that surgery is practical to relieve troublesome tinnitus and hearing loss in appropriate cases with aberrant ICA.

The purpose of this paper is to examine personal values and entrepreneurship in a Muslim society. Some insights are taken from Minangkabau entrepreneurs who come from a devoted Muslim society in Indonesia. They are migrant entrepreneurs who go to new environments which offer intense business competition. This represents a huge challenge for them. The present study used individual interviews of a sample of 15 Minangkabau entrepreneurs. Four themes have been identified from the interviews and they indicate that most of the interviewees see Islam and Minangkabau culture as providing the stimulus for becoming entrepreneurs. They do however encounter difficulty in achieving a balance between individualism and collectivism in their current situations. The paper highlights the uneasiness of entrepreneurs within a Muslim society seeking to maintain their own values without these inhibiting organisational innovations. To the authors’ knowledge this is the first study which addresses the importance of values among Minangkabau entrepreneurs in dealing with a new emerging and dynamic market (Indonesia). The present study has also identified some problems in implementing innovation among Minangkabau entrepreneurs within the context of both Minangkabau and Muslim values.

Siguiendo el creciente interes en identificar si los rasgos de personalidad estan asociados con la propension a participar en comportamientos contraproducentes en el trabajo (CCTs), el objetivo de este estudio fue investigar la relacion entre rasgos de personalidad segun el modelo de los cinco grandes factores (CGF) y CCTs. Los participantes del estudio fueron 381 trabajadores, con diferentes niveles socioeconomicos y educativos, de organizaciones publicas y privadas, provenientes de dos regiones del pais. Los factores amabilidad, escrupulosidad e inestabilidad emocional presentan correlaciones estadisticamente significativas con tres dimensiones del CCT. Analisis de regresion lineal revelaron que los cinco rasgos de personalidad contribuyeron para la prediccion de las dimensiones del CCT. Los resultados son discutidos con base en la literatura internacional.

The derivation of a marine gravity field from satellite altimetry over permanently ice-covered regions of the Arctic Ocean provides much new geophysical information about the structure and development of the Arctic sea floor. The Arctic Ocean, because of its remote location and perpetual ice cover, remains from a tectonic point of view the most poorly understood ocean basin on Earth. A gravity field has been derived with data from the ERS-1 radar altimeter, including permanently ice-covered regions. The gravity field described here clearly delineates sections of the Arctic Basin margin along with the tips of the Lomonosov and Arctic mid-ocean ridges. Several important tectonic features of the Amerasia Basin are clearly expressed in this gravity field. These include the Mendeleev Ridge; the Northwind Ridge; details of the Chukchi Borderland; and a north-south trending, linear feature in the middle of the Canada Basin that apparently represents an extinct spreading center that "died" in the Mesozoic. Some tectonic models of the Canada Basin have proposed such a failed spreading center, but its actual existence and location were heretofore unknown.

Migraine, an episodic headache disorder, is one of the most common complaints encountered by primary-care physicians and neurologists. Nevertheless, it remains underdiagnosed and undertreated. Rational migraine treatment necessitates an accurate diagnosis, identification and removal of potential triggering factors, and, frequently, pharmacologic intervention. Effective management also includes establishing realistic expectations, patient reassurance, and education. The choice of medication (abortive, symptomatic) for an acute attack depends on such factors as the severity of the attack, presence or absence of vomiting, time of onset to peak pain, rate of bioavailability of the drug, comorbid medical conditions, and side-effect profile. Effective agents for acute attacks include simple or combination analgesics, nonsteroidal anti-inflammatory drugs, ergot derivatives, selective serotonin agonists, and antiemetics. Opioid analgesics are unnecessary for most patients. The choice of preventive (prophylactic, interval) medication depends primarily on comorbid medical conditions and side-effect profile. Useful preventive agents include beta-adrenergic blockers, calcium channel blockers, tricyclic antidepressants, anticonvulsant medications, and serotonin antagonists.

Abstract Introduction: On August 13, 2021, India completed 30 weeks of vaccination against COVID-19 for its eligible citizens. While the vaccination has made progress, there has been no study analyzing the federal/union vaccine policy and its effect on vaccination coverage across Indian states. In this context, this study analyses the federal vaccination policy and its effect on interstate variation in vaccine coverage and the correlation of state economy with vaccination coverage. Methods: The study analyses vaccine policy documents, secondary data on vaccination coverage and state gross domestic product (GDP) available in public domain. ANOVA test has been used to assess the effect of vaccine policy on interstate vaccine coverage and correlation-regression analysis has been conducted to assess the type and strength of association between gross state domestic product and vaccination coverage. Results: Interstate variation in vaccination coverage in the first 15 weeks was the least (F=3.5), when vaccine procurement and supply was entirely provided by the union/federal government and vaccination was limited to priority groups. However, with the extension of vaccine policy to other groups and reduction in federal government involvement in vaccine procurement, the interstate variation in vaccination coverage increased significantly (F=10.74) by the end of 30 weeks. The highest interstate variation was observed in the period between 23-30 weeks (F=25.31). State GDP was positively and strongly correlated with state vaccination coverage with a high coefficient of correlation (R=0.94) and high coefficient of determination (Rsqaure= 0.88). Conclusions: The study finds that federal procurement and supply of vaccination among prioritized groups has been the best strategy till date to address the inequity in vaccination coverage across the states of India.

" T H E R E IS LOTS OF SMALL TALK but little small writing," Robin Lakoff writes in her recent book on language and power, in which she explains that "one does not embark on the task of writing unless there is good reason to do so." The extent and nature of the diaries of the Crease family women of Victoria demonstrate some of the good reasons that nineteenth-century women had for writing about their daily lives. Sarah Crease, wife of Henry Pering Pellew Crease, Judge of the Supreme Court of British Columbia, was a pillar of Victoria society; her daughters Mary, Susan, Barbara, and Josephine were educated in reading, writing, drawing, and painting. Several of these women (perhaps all) kept many volumes of diaries. Their many diaries were definitely small in size. Sarah, Susan, and Josephine each wrote during various years in Standard Life Assurance Company's Colonial Almanacs, books measuring only 6.5 cm X 9.5 cm. These books listed the months dates and key events on the left-hand side, with the blank right-hand page labelled "memoranda." These tiny books hardly gave them room for much expression beyond brief notes, but the women nevertheless tried to accommodate what they had to say to the small size of the page, writing in the margins and drawing balloons around long entries to squeeze their writing into the minimal space allotted. Such little books precluded elaboration or lengthy reflection on the inner life. As a result, the diaries look at first glance to be just as "small" in content as in size. The women wrote about the weather, visits, rides, and teas; they recorded the ordinary domestic round of women of their class. However, these little diaries represented a

Thin films of Bi2Te3 were grown on mica (001) substrates by hot wall epitaxy (HWE). Reflection high energy electron diffraction (RHEED) patterns of deposited films indicated that the film condition depends on the substrate temperature in the film growth process, and the epitaxial Bi2Te3 single crystal films were grown with two-steps substrate temperature control. The X-ray diffraction (XRD) pattern indicated that the Bi2Te3(0001) single crystal film was grown on the mica substrate with c-axis oriented perpendicular to the substrate plane. The microstructure of the Bi2Te3 film was examined by scanning electron microscope (SEM), and the layered structure was observed. The deviation from stoichiometric composition causes the change in the conduction character, the film with an excess of tellurium is n-type and with an excess of bismuth is p-type. Hall concentrations for n- and p-type films were 2.4×1025/m3 and 3.1×1025/m3 respectively: The Seebeck coefficient α and the power factor α2/ρ for n-type film were -237μV/K and 2.6×10-3W/(K2m) at 293K, and those for p-type, 141μV/K and 0.55×10-3W/(K2m).

AbstractThe Effects of Lithium on the Human Visual System is the first clinical monograph published in the 11 year history of Cutaneous and Ocular Toxicology. It is worthy of this unique distinction because a scientific or clinical monograph should summarize in one reference all knowledge about a particular topic to benefit both current and future scientists and physicians. This monograph on the visual side effects of regular lithium use achieves that objective admirably.

Propagation of electromagnetic pulses in transmission lines, waveguides, and optical fibers is an important topic in the design of telecommunication, signal processing, and VLSl systems. Modern undergraduate and graduate programs in electrical and computer engineering often include this topic in their curricula. Static displays of scalar or vector fields are usually not sufficient to illustrate the complexity of the propagation process, particularly when dispersion and attenuation are considered. We describe use of the MATLAB and WAVEFRONT Data Visualizer software to provide a dynamic view of the pulse propagation process in a variety of situations. The propagation process itself is described by a cascade of linear filters that represent different mechanisms of signal distortion. The modeling and simulation of this process are performed using MATLAB. Data are then filtered and exported into WAVEFRONT. Libraries of signal waveforms and filters are provided for a variety of common configurations used in optical and microwave engineering. Extension of this work to cover nonlinear propagation effects is under investigation.

BACKGROUND
The purpose of this study was to carry out two randomised phase II trials of S16020, a new olivacine derivative, tested as a single agent in patients with recurrent head and neck cancer, using methotrexate as the control arm to validate the results.
PATIENTS AND METHODS
S16020 at either 80 or 100 mg/m2 was administered as a 3-h infusion every 3 weeks. Methotrexate, 40 or 50 mg/m2, was given by bolus injection, weekly for a minimum of 6 weeks. In total, 36 patients were entered in the randomised studies (25 in an initial study, 11 in a confirmatory study) of whom 24 received S16020 and 12 received methotrexate.
RESULTS
A scheduled interim analysis showed one patient having a non-confirmed objective response with S16020 and three patients having a confirmed objective response with methotrexate. In the methotrexate group, there were no patients with severe non-haematological toxicity. With S16020, there was a high incidence of severe non-haematological toxicities, including asthenia, oedema of the face, oedema and pain at the tumour sites and erythematous rash; consequently, both studies were stopped.
CONCLUSIONS
Both studies were stopped due to the poor anticipated benefit/risk ratio for S16020, although time to progression and overall survival time were similar in both treatment arms.

Although these two fascinating volumes in many ways complement each other, Carnal Knowledge, which is solely concerned with England, is likely to be of greater interest to a non-specialist reader of this Journal than is Judging Faith, Punishing Sin. This is because the latter is a collection of 25 short articles (each by a recognised expert in his or her field) dealing almost exclusively with, and in part contrasting, protestant consistories in Scotland, mainland Europe and to some extent further afield with Roman Catholic inquisitions, whereas the former is concerned almost entirely with the English courts. Individual historians necessarily have their own specialties and the study of inquisitions and consistories have in the past followed parallel trajectories or, as the introduction to Judging Faith, Punishing Sin states: ‘For all the rich insight yielded . . . scholarship on Catholic and Calvinist programs of discipline has remained in two divergent and self-contained fields of research and discourse’ (p 2). Judging Faith, Punishing Sin is aimed at bringing together these differing fields of scholarship and, in so doing, it threads together three themes: the bureaucratic framework of early modern inquisitions and consistories; consistories and inquisitions in action; and the expanding reach and decline of ecclesiastical discipline. The breadth of field is necessarily immense but, judging from these articles, there is a growing interest in a comparative approach, the fruits of which are likely to throw greater light on each of the institutions concerned and those persons involved with them. Although all such scholarship is both complicated and limited by the extent to which court records have survived, historians are becoming increasingly aware of the treasures to be mined from those that have survived. Indeed, while this reviewer was reading the volume in question, the Times Literary Supplement (8 December 2017) included an article by another historian, Suzannah Lipscomb, entitled ‘Magdaleine’s dance’ and outlining ‘what court records can tell us about the lives of women in early modern France’. It is therefore not surprising that court and inquisitorial records throw a light, not only on the machinery of the institutions themselves and their administrators, but on the lives of the everyday men and women who 3 7 0 B O O K R E V I E W S

Abstract Significant evaporation of pure aerosols in a Volatility Tandem Differential Mobility Analyzer (V-TDMA) creates two Condensation Particle Counter (CPC) response peaks. Two hypotheses for the observed peaks have been proposed: the existence of two phases or the separation of the singly charged experimental size distribution from the remaining experimental size distributions with charges greater than 1 (charge separation). To explore this observation, we atomized pure levoglucosan aerosol and evaporated the aerosol until two peaks formed. We used an additional classifier and neutralizer to select particles from each of the two peaks and assessed the number of charges on the particles. The smaller diameter peak contained singly charged particles, and the larger diameter peak contained the remaining charges. The charge separation hypothesis alone accounts for the two-peak observations. We used a new V-TDMA model named TAO and show that charge separation should occur in other pure components as well. The TAO model was then used to display the impact of different DMA transfer functions, different inlet size distributions, and different oven residence time distributions (RTDs) on the CPC response. Large errors are possible when direct measurement of the RTD is not performed or when wide RTDs are used. We recommend use of narrow transfer functions with narrow RTDs to detect charge separation. When the singly charged CPC response is isolated (smaller diameter peak in the two peak response), accurate estimations of vapor pressure can be recovered, assuming accurate values for gas phase diffusivity, surface energy, particle density, etc. are used.

Biomass surrounds us from the smallest alga to the largest redwood tree. Even the largest trees owe their strength to a newly-appreciated class of nanomaterials known as cellulose nanocrystals (CNC). Cellulose, the world's most abundant natural, renewable, biodegradable polymer, occurs as whisker like microfibrils that are biosynthesized and deposited in plant material in a continuous fashion. Therefore, the basic raw materials for a future of new nanomaterials breakthroughs already abound in the environment and are available to be utilized in an array of future materials once the manufacturing processes and nanometrology are fully developed. This presentation will discuss some of the instrumentation, metrology and standards issues associated with nanomanufacturing of cellulose nanocrystals. The use of lignocellulosic fibers derived from sustainable, annually renewable resources as a reinforcing phase in polymeric matrix composites provides positive environmental benefits with respect to ultimate disposability and raw material use. Today we lack the essential metrology infrastructure that would enable the manufacture of nanotechnology-based products based on CNCs (or other new nanomaterial) to significantly impact the U.S. economy. The basic processes common to manufacturing - qualification of raw materials, continuous synthesis methods, process monitoring and control, in-line and off-line characterization of product for quality control purposes, validation by standard reference materials - are not generally in place for nanotechnology based products, and thus are barriers to innovation. One advantage presented by the study of CNCs is that, unlike other nanomaterials, at least, cellulose nanocrystal manufacturing is already a sustainable and viable bulk process. Literally tons of cellulose nanocrystals can be generated each day, producing other viable byproducts such as glucose (for alternative fuel) and gypsum (for buildings).There is an immediate need for the development of the basic manufacturing metrology infrastructure to implement fundamental best practices for manufacturing and in the determination of properties for these for nanoscale materials and the resultant products.

We propose an Advanced Mobility Handover scheme (AMH) in this paper for seamless mobility in MIPv6-based wireless networks. In the proposed scheme, the mobile node utilizes a unique home IPv6 address developed to maintain communication with other corresponding nodes without a care-of-address during the roaming process. The IPv6 address for each MN during the first round of AMH process is uniquely identified by HA using the developed MN-ID field as a global permanent, which is identifying uniquely the IPv6 address of MN. Moreover, a temporary MN-ID is generated by access point each time an MN is associated with a particular AP and temporarily saved in a developed table inside the AP. When employing the AMH scheme, the handover process in the network layer is performed prior to its default time. That is, the mobility handover process in the network layer is tackled by a trigger developed AMH message to the next access point. Thus, a mobile node keeps communicating with the current access point while the network layer handover is executed by the next access point. The mathematical analyses and simulation results show that the proposed scheme performs better as compared with the existing approaches.

Pharmacokinetic data were obtained from four healthy volunteers after oral administration of a single 400 or 600 mg dose of enoxacin. Enoxacin was absorbed quickly and absorption was increased when enoxacin was ingested after a meal. Renal clearance of enoxacin and 4-oxo-enoxacin decreased after simultaneous administration of probenecid. In addition, pharmacokinetic parameters of enoxacin and its 4-oxo metabolite were determined for plasma and sputum from 19 patients treated with enoxacin, 400 or 600 mg bd, for a respiratory tract infection. The half-life of both enoxacin and 4-oxo-enoxacin was 5-6 h; during treatment with 400 and 600 mg bd, the plasma concentrations exceeded MIC values for most bacteria isolated in respiratory tract infections, including most Pseudomonas aeruginosa strains; Streptococcus pneumoniae was an exception. Diffusion from plasma to sputum was approximately 100%. Of an ingested dose, 60-65% was recovered in the urine in 24 h. In a third study, a single 600 mg dose of enoxacin was given to 15 patients undergoing thoracotomy. Subsequent lung tissue concentrations of enoxacin were significantly higher than plasma concentrations at the same time after ingestion.

This study explored how a school-based speech—language pathologist implemented a classroom-based service delivery model that focused on collaborative practices in classroom settings. The study used ethnographic observations and interviews with 1 speech—language pathologist to provide insights into how she implemented collaborative consultation and classroom-based intervention service delivery models. Five themes emerged: service delivery, curriculum-based intervention, scheduling, collaboration, and advocacy. Though the participant implemented a full range of service delivery models, findings provide helpful ideas for others implementing inclusive and collaborative practices in classroom settings.

In this study, we report experimental results on the dictator decision collected in two neighboring ethnic minority groups, the matrilineal Mosuo and the patriarchal Yi, in southwestern China. We follow the double-blind protocol as in Eckel and Grossman (in Handbook of experimental economics results, 1998), who find that women in the U.S. donate more than men. We find this pattern reversed in the Mosuo society and find no gender difference in the Yi society. This is highly suggestive that societal factors play an important role in shaping the gender differences in pro-social behavior such as dictator giving.

This slim volume provides a glorious pictorial record of the now-famous Lod mosaics. I was fortunate to see the mosaics in situ during the summer of 2009 and to curate the first exhibition of the mosaic, held at the Metropolitan Museum of Art in New York between September 28, 2010 and April 3, 2011. The principal floors then embarked on a prolonged world tour (8), being exhibited at 8 other venues in America and Europe (cf. figs. 2-3, photographs of the installations at the Louvre in Paris and the Altes Museum in Berlin). The lifting of the mosaics in the fall of 2009 (delayed until after an official visit by the Prime Minister of Israel) provided much valuable information about the techniques and practicalities of mosaic working (45 and 70-71; fig. 52). It also revealed the existence of what is called here “a second mosaic”, which would be fully exposed in 2014 (46-48 and 94-98). The mosaics are now back in Israel in storage; it is planned to return all of them to Lod so that they can be displayed “on the original spot” in a purpose-built museum to be named the Shelby White and Leon Levy Lod Mosaic Center (8),1 where they will doubtless prove to be a major tourist attraction.

RESUMO
A Unidade de Terapia Intensiva e um setor de alta complexidade onde os pacientes criticos passam por periodos de observacao continua em um ambiente frio e pouco acolhedor, e por vezes assustador na visao dos pacientes e familiares. Nesse sentido a visita humanizada multidisciplinar busca promover melhor compreensao deste contexto e esclarecer as duvidas e insegurancas geradas por esse ambiente garantindo assim, uma assistencia de melhor qualidade. Buscou-se, portanto, relatar a experiencia da visita humanizada multidisciplinar em uma unidade de terapia intensiva. A visita humanizada ocorre, com a participacao em conjunto do medico, enfermeiro, psicologo e fisioterapeuta. A equipe recebe os familiares na sala de espera da UTI, realiza acolhimento, avaliacao psicologica e intervencao breve, de apoio e orientacao, e preparo psicologico para a visita. Quando necessario a equipe multidisciplinar, acompanha o visitante beira-leito, para proporcionar o acolhimento das duvidas que surgem ao ver o paciente. Ao final do horario de visitas, realiza-se o boletim medico com a participacao interdisciplinar, onde o medico informa a evolucao clinica do paciente, discute o caso com a familia e a equipe, a fim de proporcionar que o paciente receba a melhor terapeutica. A visita humanizada interdisciplinar e finalizada apos o boletim, quando o psicologo realiza o atendimento com a familia, com o objetivo de compreender a percepcao do familiar sobre o momento atual e impacto emocional reativo ao momento vivenciado. Encerra-se o processo com a evolucao no prontuario do paciente, onde sao informados os principais pontos que sao identificados no momento da visita.

Die Unterscheidung des Guten und Gerechten sowie die Vorrangstellung des Gerechten vor dem Guten werden fur eine Kantische Ethik als unumganglich angesehen. Die Frage nach der genauen Bestimmung der Unterscheidung sowie der Vorrangrelation hat weite Teile der praktischen und politischen Philosophie in den letzten Jahrzehnten stark gepragt.
Vereinfachend werden oft Theorien, die eine Prioritat des Gerechten vor dem Guten behaupten, als "liberal" bezeichnet. Denn als begrundungsbedurftig und begrundungspflichtig werden "nur" diejenigen Verpflichtungen angesehen, welche Interaktionen von Personen untereinander regulieren; das gute Leben des Einzelnen ist weder allgemein begrundungsfahig noch begrundungspflichtig. Klassisch liberale Theorien nehmen eine Sortierung von Belangen vor in solche, die das eigene Leben betreffen, und solche, die das Zusammenleben (in bestimmter Weise) betreffen. Bezweifelt wird vielfach, dass diese Sortierung uberhaupt allgemein vorzunehmen moglich ist. Weiterhin wird moniert, die Bedeutung von Gerechtigkeit sei nicht angemessen wiedergegeben in einer Theorie, die sie unabhangig vom Guten inhaltlich festlegt; gerade weil und insofern ein Gutes geschutzt wird, sei Gerechtigkeit der prioritare praktische Beurteilungsgesichtspunkt. Theorien, die das Gerechte als Teil des Guten begreifen sind nicht so einfach unter einen Begriff zu subsumieren: denn sie argumentieren sehr verschieden gegen die Moglichkeit der Unterscheidung und/oder die behauptete Prioritat und werden unter ganz verschiedenen Titeln gefuhrt wie Essentialismus, Kontextualismus, Kommunitarismus usw. Eine wichtige diese Theorien einigende These ist, dass Gerechtigkeit in Verschrankung mit dem Guten allererst ihre Bedeutung erhalt. Als politische Philosophien sind sie in Gestalt republikanischer Theorien, die gemeinsame Prozesse der Meinungs- und Willensbildung zentral vorsehen, wichtige Gegenspieler liberaler Theorien.
Die gegenwartig neu entwickelten deliberativen Theorien der Gerechtigkeit, wie ich sie nenne, haben einen Ausweg aus dieser Lage versucht zu explizieren: Sie sind liberal, indem sie die Unterscheidungs- und Vorrangthese vertreten; sie vertreten zugleich aber die Verschrankungsthese, mithin die These, dass das Gerechte auf das Gute zu beziehen ist, um prioritare Gerechtigkeitsurteile allererst zu gewinnen. Auch sind sie in unterschiedlicher Weise auf Prozesse der gemeinsamen Meinungs- und Willensbildung ausgerichtet, sind demnach auch republikanisch. Deliberative Theorien der Gerechtigkeit begreifen die Richtigkeit moralischer Urteile, auch Urteile der Gerechtigkeit, vermittels ihrer vernunftigen Akzeptabilitat, in Gestalt vernunftiger Zustimmung oder eines vernunftigen Konsenses. Als Vertreter deliberativer Theorien werden in diesem Text analysiert die Autoren John Rawls, Thomas Scanlon und Jurgen Habermas, da sie breit angelegte Theorien vorgelegt haben, die wesentliche Alternativen solcher Ansatze abmessen. Zudem haben sie methodisch ausgefeilte Deliberationsmodelle entwickelt, die es ermoglichen, vernunftige Akzeptabilitat auszubuchstabieren: Rawls mit seinem Uberlegungsgleichgewichtsmodell, Scanlon mit seiner Konzeption substanzieller Grunde und Habermas mit seinem Diskursmodell.
Wie genau ein kantisches, liberales, Gerechtigkeitsverstandnis auszubuchstabieren ist, ist unter den genannten Autoren deliberativer Theorien der Gerechtigkeit strittig. Einig sind sie darin, das Gute und das Gerechte begrifflich voneinander unabhangig zu bestimmen, inhaltlich aber miteinander zu verschranken; einig sind sie mithin in einem bestimmten Modell der Scheidung und zugleich Verschrankung des Guten und Gerechten. Nicht aber darin, wie genau dieses Modell zu explizieren ist. Rawls, Scanlon und Habermas haben je bestimmte Modelle der Gut/Gerecht-Unterscheidung entwickelt. Das prominenteste ist sicherlich das Komplementaritatsmodell, bei dem das Gute die Hinsicht der Gerechtigkeit bildet (Rawls). Das Integrationsmodell sieht vor, diejenigen Aspekte des guten Lebens in die Gerechtigkeit einzuschreiben, die allgemein begrundbar sind (Habermas). Ein Modell, das das Verhaltnis als offene Komplemente fasst (Scanlon), verneint, dass das gute Leben fur die Zwecke der inhaltlichen Bestimmung von Gerechtigkeit einheitlich konzipiert werden kann.
Die Ansatze von Rawls, Habermas und Scanlon stellen den Versuch dar, entgegen der klassischen Alternative, entweder das Gute ganzlich unberucksichtigt zu lassen oder das Gerechte darin zu integrieren, das Gute mit dem Gerechten zu verschranken und doch die Vorrangstellung des Gerechten zu sichern, mithin die klasssich liberale Moralarchitektonik beizubehalten. Dass diese Vorhaben in bestimmten Hinsichten deren zentrale Anspruche verfehlen, wird durch eine jeweils interne Kritik gezeigt. Ziel ist zu zeigen, dass der "Moglichkeitsraum" alternativer moralphilosophischer Positionen, der durch diese Autoren aufgemacht wird, in charakteristischer Weise eingeschrankt ist.
The distinction between the good and the right as well as the priority of the right over the good are seen as unavoidable for Kantian ethics. Questions concerning modelling this distinction and this priority relation had a strong influence on many aspects of practical and political philosophy over the last decades.
Simplistically, theories that claim a priority of the right (aka the just) over the good are often called "liberal". That is because "only" obligations that regulate interactions of persons are regarded as being capable of, and as requiring, a justification. Individuals' good life is seen as neither generally capable of nor requiring a justification. A liberal understanding of justice, it seems, depends strongly on the distinction between what each individual is responsible for and what society or - more narrowly - state institutions are responsible for. Occasionally justice is further restricted to that part of ethics which can be enforced by state institutions (and thus becomes the normative part of law).
Theories that understand the right as a part of the good and deny the independent determination of contents or of reasons (or both) are not so easily subsumed under one concept, for they argue very diversely against the possibility of the distinction and/or the claimed priority and are to be found under quite different titles like Essentialism, Contextualism, Communitarianism etc. In political philosophy the interesting alternatives to liberalism are the republican theories that emphasise processes of collective formation of will and opinion.
Current deliberative theories of justice that are derived in a Kantian spirit are liberal in that they espouse the distinction and priority thesis in one version or the other. But they are also republican in that they affirm the entanglement of the good and the just. In this work, I analyse three central approaches to the development of a deliberative theory of justice - the approaches of Rawls, Scanlon and Habermas -and I show that they cover considerable alternatives of such theories. Different models of the good/right distinction are distinguished, analyzed and attributed to these authors. The perhaps most prominent such model is the "complementarity model" in which justice draws the limits and the good shows the point (Rawls). The "integration model", on the other hand, models the relation by only integrating into justice those aspects of the good life that are universally justifyable (Habermas). The "open model" leaves the relationship open to a large extent (Scanlon): The good life cannot be conceptualised uniformly for the purpose of determining the content of justice; a theory of the good is neither possible nor necessary.
The aim of this work is to show how the spectrum of possible deliberative theories looks like, to discuss its range and to identify its reductionisms that prevent them from being fully deliberative.

We present a mechanistic study demonstrating selective Arf–Cl bond activation preceded by η2 coordination of Pd(PEt3)2 to a C═C moiety of a partially fluorinated substrate. An intramolecular ring-walking process to activate the Arf–Cl bond is plausible, but an intermolecular reaction becomes dominant in the presence of PEt3. The latter pathway is significantly enhanced, since PEt3 promotes dissociation of Pd(PEt3)3 from the C═C moiety followed by activation of the Arf–Cl bond. Our observations also show that PEt3 can be used to control reaction selectivity. The experimental observations are supported by density functional theory (DFT) calculations (at the SMD(toluene)-DSD-PBEP86/cc-pV(D+d)Z-PP//DF-PBE+dv2/SDD(d) level of theory).

Die derzeitige Entwicklung in den USA, gepragt durch billiges Schiefergas, hat starke Auswirkungen auf die Produktion von Basischemikalien. Der Beitrag geht der Frage nach, ob sich vor diesem Hintergrund der Anteil nachwachsender Rohstoffe fur die Chemikalienproduktion steigern lasst oder ob sich die Zahl biobasierter Produkte und Verfahren eher verringern wird. Antworten liefert fur einige ausgewahlte Grundchemikalien der Vergleich von bestehenden Produktionsverfahren auf petrochemischer Basis mit Alternativen auf Basis nachwachsender oder anderer fossiler Rohstoffe (bspw. Methan und niedere Alkane).

This article uses the 1996 General Social Survey (GSS) and the 1992 National Study of the Changing Workforce (NSCW) to examine two issues: the relationship of work characteristics, family characteristics, and work-family spillover to perceptions of work-family balance; and models of “gender difference” versus “gender similarity.” The GSS analysis supports the gender similarity model. It demonstrates that work demands such as the number of hours worked per week and work spillover into family life are the most salient predictors of feelings of imbalance for both women and men. The NSCW includes subtler measures of family spillover into work as well as measures of specific job characteristics and child care. The NSCW results support a gender difference model. They indicate that when family demands reduce work quality, there is a decreased likelihood of perceived balance. However, men and women experience balance in gendered ways. Women report more balance when they give priority to family; men report less balance when they have no personal time for themselves due to work and more balance when they make scheduling changes due to family.

We measure the performance of several cooperative caching policies for a database with hot spots. The workload consists of queries and append-only update transactions, and is modeled after a financial database of stock (historical) trading information. We show that cooperative caching is effective for this application. We show that selecting the correct set of peer servers when servicing a cache miss is crucial to achieving high performance, and we demonstrate a greedy algorithm that performs close to optimal for this workload. We also evaluate several cache replacement policies and show that a 2nd-chance algorithm performs best. In a 2nd-chance algorithm, replaced pages are transferred to a peer server rather than being discarded. When a page is selected for replacement a 2nd time, the page is discarded. Our results can be applied in the design of proxy servers for databases or Web servers where a layer of proxy servers are used to scale the system performance.

We use plastic inlays that allow you to fill a tooth defect in one visit. For this purpose, plastic set teeth are used, from which the desired area corresponding to the tooth defect is cut. For reliable fixation of the plastic in the cavity of the tooth, a stainless steel wire reinforcement with a diameter of 0.6 mm is fixed. The inlay, connected to the reinforcement with a quick-hardening plastic, fills well the contours of the prepared cavity.

In the Life of Pope Constantine in the Pontifical Book the following passage occurs, describing a demonstration at Rome in favour of the Sixth Ecumenical Council (vol. l, p. 391 ed. Duchesne): huiusque rei causa zelo fidei accensus omnis coetus Romane urbis imaginem quod [some Mss. quam] Greci Botarea vocant sex continentem [w. continentes, continens] sanctos et universales synodos in ecclesia beati Petri erecta est. The difficulty is the vox nihili: Botarea [w. Botariam, Botaream, Votarea, Botarpa), s to which Duchesne merely remarks (p. 394) je ne sais d'o vient ce mot etrange'. At first sight, one would think that a series of pictures representing the six synods was put up in St. Peter's church.) But on reflexion one sees that this is in itself unlikely; and then one observes the word continentem which gives the clue. The thing which was lifted up or erected was something containing the Acts of the Six Councils, — namely a coffer or ehest. It is now easy to discern the correction of the corrupt botarea. We must read: imaginem quod Gred cibotarea vocant. Cibotarea = χιβωτάρια. It is wellknown that κιβωτός is the word used in the LXX for the ark of the covenant (της δια&ήχης) and hence it acquired a certain sacredness, and was specially used of boxes and cases in which holy relics were preserved.) Thus in the Life of Theodore of Edessa (Zitie usw., ed. by Pomyalovski, 1892) c. 86 (p. 92) we read: ένεγκων dl· χιβωτον ό βαοιλενς χεχαλνμμένην πάντο&εν xal εν έπιοήμω τόπω ταντην άνα&είς χατέ&ετο εν αυτή τύν

We propose to use high-order diffraction spots from 2-D silicon nanowire (NW) arrays for refractive index sensing based on spatial changes in the diffractive spots position. The NW arrays act both as a refractive index sensor and as dispersive elements, eliminating the need for external spectrometers for the measurement of refractive index changes. The setup uses a simple laser diode source and a low-cost camera and results in higher sensitivity to environmental refractive index changes, as compared with previously demonstrated colorimetric sensors. The sensitivity is greater for higher order diffraction spots, as compared with the lower order ones due to a larger dispersion angle change at higher orders. We also demonstrate that the observed diffraction angle and efficiency of the diffractive orders depend on a number of factors, such as excitation wavelength, NW diameters, pitch, and surrounding medium index. The simple solution of using diffraction spot displacements on a 2-D detector array would provide a novel means of sensing refractive index changes in the surrounding medium of NWs without the burden of complicated spectral analysis.

ABSTRACT Moseley’s (2016) Money and Totality focuses on two important issues: (a) the nature and significance of Marx’s notion of the “circuit of money capital” and (b) the solution to the “transformation problem”. The former question, in particular, makes this book important not only for Marx specialists but also for other dissenting economists. Recall that in writings before the General Theory Keynes (1933a, 1933b), in particular, made allusion to the Marxian circuit via the concept of the monetary theory of production. However, these references did not survive in the published version in 1936. Nor was Keynes at all confident on this topic in debate the following year. It is therefore important to both Marx scholars and other heterodox economists to inquire exactly how the Marxian circuit was supposed to work. A starting point is to write out the scheme from Capital Vol. 2 (Marx, 1885/1976) in full, M – C … P … C’ – M’, and try to explain what the magnitudes (M’ – M) and (C’ – C), are supposed to represent. This is indeed one of Moseley’s main tasks in this thought-provoking book.

Carnitine palmitoyltransferase 1β (CPT-1β) is a key regulator of the β oxidation of long-chain fatty acids in skeletal muscle and therefore a potential therapeutic target for diseases associated with defects in lipid metabolism such as obesity and type 2 diabetes. C75 [4-methylene-2-octyl-5-oxo-tetrahydro-furan-3-carboxylic acid] is an α-methylene-butyrolactone that has been characterized as both an inhibitor of fatty acid synthase and more recently, an activator of CPT-1 (Thupari et al., 2002). Using human CPT-1β expressed in the yeast Pichia pastoris, we demonstrate that C75 can activate the skeletal muscle isoform of CPT-1 and overcome inactivation of the enzyme by malonyl CoA, an important physiological repressor of CPT-1, and the malonyl CoA mimetic Ro25-0187 [{5-[2-(naphthalen-2-yloxy)-ethoxy]-thiophen-2-yl}-oxo-acetic acid]. We also show that C75 can activate CPT-1 in intact hepatocytes to levels similar to those achieved with inhibition of acetyl-CoA carboxylase, the enzyme that produces malonyl CoA. Finally, we demonstrate that concentrations of C75 sufficient for activation of CPT-1 do not displace bound malonyl CoA. We conclude that CPT-1 is an activator of human CPT-1β and other CPT-1 isoforms but that it does not activate CPT-1 through antagonism of malonyl CoA binding.

Osmotic dehydration is a method that can be used in the pretreatment of drying by immersing the material in a hypertonic solution. The purpose of this study was to examine the effect of concentration and temperature of the osmotic solution on water loss and solid gain to dragon fruit pieces during the osmotic dehydration process. Dragon fruit slices were immersed in osmotic solution with different concentration and temperature solution (30 oBrix, 50 oBrix, and 70 oBrix, as well as 30 oC, 40 oC, and 50 oC). The WL value for the concentration of 30 oBrix solution varies from 17.42% to 25.26%, for a 50 oBrix concentration is 32.84% to 50.38%, and for a 70 oBrix concentration is 39.89% to 57.99% . Thus, changes in the level of WL, concentration and temperature of the solution, where the higher the concentration and temperature of the solution, the greater the WL of the material. Meanwhile, for SG on materials, values ranged from 2.092% -10.010%. Based on the calculation of the Azuara model, the WL values ranged from 21.551% -75, 187% and 3.899% -17.575% for the SG value. The coefficient of determination for the calculation of the Azuara model is 0.938 - 0.992, thus the Azuara model can be said to be feasible for modeling the WL and SG values on osmotic dehydration of dragon fruit.

Nano - engineering technology has become the most growing trend in the world since the 20th century. How to apply nanotechnology on the environment in order to remove the decomposition of organic pollutants is the emerging subject. During the past years a preliminary study of Nano-photocatalists confirmed that Nano-TiO2, can polymerize dissolved styrene in water. Due to the direction of the study, it was divided in two major sections: (1) we first use styrene polymerization to explore the effect of temperature and size effect on polymerization and its influence in the characteristics of the product thru analysis of characteristics. (2) As a second part of the experiment, electric layers of dye-sensitized solar cells were be derived as a material to create photovoltaic energy, with a more efficient conversion and low costs of the cells. In the first section of this experiment we used TiO2 polymerization of styrene monomer at different temperatures. From the results of gel permeation chromatography and furrier infrared spectroscopy analysis, we were able to that the average molecular weight of this product was subjected to ambient polymerization temperature effect and then to variation result. Can also be learned that in high and low temperatures, polymerization environment can proceed to react at 3000 cm-1 which is the signal of aromatic functional group, and at 1400 cm-1 which is the signal of alkaline functional enhance; this might be surmised at low and high temperature, to conduct it to environment polymerization of styrene monomer, where the addition of TiO2 can affect its polymerization reaction. Different sizes of TiO2 where exposed in to UV light, after that procedure some of the samples where activated and another part of them was not activated, after this application we proceed to polymerization process of vapor styrene monomer. In different processing times, chromatography analysis was used to measure gas concentration, the result can be known by light activation of Nano-TiO2 polymerization, where the removal of styrene gives as a result the best effect with a removal rate of 97.57%. The obtained product was in a solid-state; nuclear magnetic resonance analysis can be aware from 180 to 400 ppm of chemical shift signals of the polystyrene by carbon signal; however the chemical shift signals from 19 to 160ppm are not from polystyrene. Instead TiO2 polymerization of acetylene structure from the product is more similar. Fourier infrared spectroscopy was used to analyze the infrared spectrum of the product, showing an aromatic functional group signal at 3000 cm-1, as the same showed a methylene functional group signal at 2940 cm-1, an alkaline functional group signal at 1400 cm-1 , and a terminal vinyl functional group signal from 1000 to 500 cm-1 .If this product is compared with literature about Fourier infrared spectrum of polyacetylene, previous conjunction on this polymer can be confirmed. Using differential scanning calorimetric analysis of polymers, as a result we can obtain a product formed at 90 to 100°C , having a Tg, and a product formed at 160°C , having a Tg. From the gel permeation chromatography we can obtain the average of molecular weight, which is greater than 1000 which is a polymer compound, we can obtain too, the structure characteristics of this product, it was found that it posses polystyrene and polyacetylene of copolymers. In the second section of this experiment, synthesization of polymer made of dye-sensitized solar cells was performed, as the same the measure of photovoltaic energy conversion. As a result energy conversion rate of photovoltaic cells immersed in pure TiO2 showed to be low when compared to one half of the solar cells.

Conventional reinforced concrete designs will have to be altered when designing a guideway for a maglev using an electrodynamically suspended (EDS) propulsion system. This type of propulsion system generates large magnetic fields that will develop magnetically induced, circulating eddy currents in any conventional steel reinforcement in close proximity to the magnets. These eddy currents, if large enough, may produce significant power losses that could adversely effect operation of the system. This paper presents a method and explanation for civil engineers to use for estimating the power losses due to the presence of metallic reinforcement. This procedure may be used to help guide future designs in the selection and placement of reinforcing material.

Purpose – The purpose of this paper is to present the optimal design of a low-cost interior permanent magnet (IPM) alternating current (AC) motor. It examines the influence of the permanent magnet (PM) materials, and proposes a simple and practical method of optimizing the air-gap field to achieve sinusoidal back electromotive force (EMF), and to reduce the cogging torque. Design/methodology/approach – IPM AC motors with different magnet materials and various topologies are comparatively studied. Finite element method (FEM) is used to predict the performances of these designs. Material costs and manufacture costs are both taken into account. Finally, an optimized design is prototyped and tested, validating the design considerations. Findings – In an IPM AC motor, even if the rotor outer profile is round, the air-gap field distribution can be fined, while the cogging torque can be significantly reduced, by properly shaping the stator tooth tips. Nevertheless, this technique is usually applicable to motor c...

Optimal policies for a batch packed distillation unit are examined for the cases of variable reflux ratio and variable boilup rates. This work was to act as a follow-up to Converse's work(1) for a batch plate distillation column with variable reflux policy. For the cases studied, it would seem that the boilup rate optimal policy yields better performance for the still than the reflux ratio optimal policy. The results of the present analysis and those of other authors seem to indicate that more effort should in the future be devoted to new modes of operation rather than to various refinements of the model used in the present and past studies. The present exploratory work seems to support the need for further studies using a packed rectifying section with variable boilup policy along with a novel mode of operation such as that considered by Mayur et al,(6).
On a etudie les meilleures methodes de fonctionnement d'un appareil garni pour distillation discontinue en considerant les cas ou le rapport de reflux et les vitesses d'ebullition variaient. Le present travail avait pour but de faire suite a celui de Converse(1) relativement a une colonne avec plateau pour distillation discontinue et ou le reflux etait variable. Il semblerait que, dans les cas etudies, la methode optimale basee sur la vitesse d'ebullition a donne un meilleur rendement que celle qui reposait sur le rapport de reflux. Les resultats de l'etude actuelle et ceux d'autres auteurs semblent indiquer qu'a l'avenir on devrait consacrer des efforts plus grands pour obtenir de nouveaux modes d'operation plutot que differentes ameliorations du modele utilise dans les etudes actuelles et passees. Le present travail d'exploration semble appuyer le point qu'il faut faire d'autres etudes en employant une section garnie de rectification et une methode d'ebullition variable ainsi qu'un nouveau mode d'operation tel que celui que Mayur et d'autres consideraient(8).

Resumo—Este artigo propõe um método para a estimação conjunta das variáveis de estado e da topologia da rede no contexto da modelagem em tempo real do sistema elétrico de potência. A proposta considera a representação de determinadas regiões do sistema no nível de seção de barra, explicitando os dispositivos chaveáveis nelas contidos. As informações sobre os status de disjuntores e chaves são tratadas como informação a priori sobre a topologia, a ser processada por um estimador de estados ortogonal especializado, tendo como base as rotações rápidas de Givens. Além das tensões complexas nas barras, este estimador determina a topologia da rede com base nas medidas analógicas disponíveis, o que permite validar ou corrigir a topologia inicialmente presumida. O método também possibilita o processamento de erros grosseiros em medidas analógicas. A metodologia proposta é avaliada e validada através de estudos de casos conduzidos com o sistema-teste de 30 barras do IEEE.

Savitzky–Golay (SG) filtering, based on local least-squares fitting of the data by polynomials, is a popular method for smoothing data and calculations of derivatives of noisy data. At frequencies above the cutoff, SG filters have poor noise suppression; this unnecessarily reduces the signal-to-noise ratio, especially when calculating derivatives of the data. In addition, SG filtering near the boundaries of the data range is prone to artifacts, which are especially strong when using SG filters for calculating derivatives of the data. We show how these disadvantages can be avoided while keeping the advantageous properties of SG filters. We present two classes of finite impulse response (FIR) filters with substantially improved frequency response: (i) SG filters with fitting weights in the shape of a window function and (ii) convolution kernels based on the sinc function with a Gaussian-like window function and additional corrections for improving the frequency response in the passband (modified sinc kernel). Compared with standard SG filters, the only price to pay for the improvement is a moderate increase in the kernel size. Smoothing at the boundaries of the data can be improved with a non-FIR method, the Whittaker–Henderson smoother, or by linear extrapolation of the data, followed by convolution with a modified sinc kernel, and we show that the latter is preferable in most cases. We provide computer programs and equations for the smoothing parameters of these smoothers when used as plug-in replacements for SG filters and describe how to choose smoothing parameters to preserve peak heights in spectra.

The integrated absorption cross section of the main lines in the far‐IR spectrum of the group‐V donors Sb, P, and As and the group‐III acceptors B, Al, Ga, and In in germanium has been determined for impurity densities in the range of 1012–1014 atoms/cm3. The cross sections and consequently the experimental oscillator strengths for transitions from the ground state, decrease gradually with increasing ground‐state energy. In compensated samples the electric field due to the ionized impurities strongly affects the relative line strengths; neutralizing by band‐gap illumination allows one to minimize the effect of the electric field and to observe simultaneously the majority and minority impurities, allowing one to calculate the compensation.

Abstract Living Life to the Full 55+ (LLTTF) was an 8-week, 12-hour, community educational program based on CBT principles. The program aim was to teach participant skills and techniques to cope effectively with life stress. Participants self-referred to the program by responding to advertisements or were otherwise referred to the program by local community centres. Following the promising results of the pilot study, a follow-up empirical study was conducted to assess the impact of the program on clinical measures and other notable measures over time. Study participants (N = 514) were recruited at partner sites hosting the program. Demographic and other data was collected to assess the impact of the program. Measures collected to assess the impact of the program were the Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI), Warwick-Edinburgh Mental Well-being Scale (WEMWBS), and a brief measure of loneliness/social connectedness. Participant data was collected pre/post-intervention, and at post-course follow-up periods (3/6/9-months). Preliminary repeated-measures ANOVA analyses found statistically significant changes in depression, anxiety, mental well-being, and loneliness scores, from pre- to post-intervention. Participant’ depression, anxiety, and loneliness scores significantly reduced from pre- to post-course. Participants also experienced a significant improvement in mental well-being from pre- to post-course. Observed decreases in loneliness and depression did not significantly change from post-course to any of the follow-up periods. Results suggest the viability of a nonclinical program for addressing depression and loneliness in older individuals, and have implications for community-based strategies attempting to address mental health issues in older Canadians

A parabolic reflectarray antenna has been proposed to generate a complete cellular coverage in transmission to provide broadband services from a communication satellite in Ka-band. Two different approaches have been evaluated to design a parabolic reflectarray able to generate four spaced beams per feed in four different combinations of frequency and polarization. A 1.8 m parabolic reflectarray has been simulated when it is illuminated by a feed block of 27 horns. The results show the capacity to generate 108 spot beams in good agreement with the requirements imposed in satellite communications. The proposed concept could be used to reduce the number of on-board antennas and feed chains required to generate a multispot coverage in Ka-band.

I HAVE some hesitationin presentingthis paper. It containsno new research,no recordsof detailed laboratory experimentsand no results of any new biochem.ical test or instrument of diagnosis. It merely containsa few reflectionsthat have resulted from observationsmade during the performanceof routine medical work. The greatestprivilege and the most boundenduty devolving on the medical professionis the prevention of disease. At present,however,exceptin comparatively few diseases,we are unable to exercise this privilege, partly from lack of opportunity and organization,but also from a paucity of knowledge with regard to the causationand mode of origin of many common diseases.Routinemedical inspection is as yet too limited to be of any very great value, and even should it becomemore general in its application,would have to be carried out in a .most thoroughand painstakingmannerin order to be really effective. Consequently,the next best thing available is a close study of the early phenomenaof disease,what are their manifestations, and what measurescan be undertakento arrestor cure them. Many patientssuffering from common chronic diseasespass through our hands with the condition unrecognized,or even if it is recognized, the patients may receive inadequate treatment.The subjectof this paperhasbeenchosen largely becausea considerablepercentageof the patientswhom I have seen,sufferedfrom advanced and often incurabledisease. From a consideration of the pasthistory of suchpatients,an attempthas been made to determine what were the earliest manifestationsof their disease,and whether any measuresmight have beenadopted to stay their course. A patient may exhibit undoubted evidence indicating the possibility or even probability of serious diseasein the future, and yet at the time may look andfeel perfectlywell. Thereis a distinct dangerthat he may be lulled into a senseof false security, and the golden opportunity for effective treatmentmay be missed. This propositionwill be

Abstract Exploration was conducted to be used for genetic variation improvement of abaca germplasm. It was performed at Sangir Besar Island in Sangihe Achipilago and Karakelang Island in the Talaud Archipilago, both of them were located in the teritorial of Sangihe-Talaud District of North Sulawesi Province, in September 1999. Result indicated that Sangihe-Talaud District had many species of abaca introduced from Philippina. Fifteen accessions of abaca were collected. The difference characters of each accession were identified by stem colour, bloom shape and colour, stem height and diameter, and fibre strength. Those accessions were conserved in the RITFCrs Experimental Garden for characterization and evaluation. Abstrak Untuk memperluas keragaman sumber daya genetik tanaman abaca, telah dilakukan eksplorasi di Pulau Sangir Besar di gugusan Kepulauan Sangihe, dan di Pulau Karakelang di gugusan Kepulauan Talaud, Kabupaten Sangihe-Talaud, Propinsi Sulawesi Utara, pada bulan September 1999. Dari eksplorasi tersebut diketahui bahwa di Kabupaten Sangihe-Talaud, Propinsi Sulawesi Utara khususnya di Pulau Sangir Besar dan Pulau Karakelang, banyak terdapat jenis abaca yang diduga berasal dari Filipina. Diperoleh 15 aksesi abaca dari kedua pulau tersebut. Perbedaan yang mencolok dari masing-masing aksesi terletak pada karakter warna batang, warna dan bentuk jantung, tinggi dan diameter batang serta kekuatan seratnya. Aksesi-aksesi tersebut ditanam di kebun plasma nutfah Balittas untuk karakterisasi dan evaluasi.

Abstract Sulphur was extracted from 48 Finnish soil samples with 0.01 M CaCl2-solution and with 0.5 M CH3COONH4-0.5 M CH3COOH (pH 4.65), abbreviated here as AAAc. Sulphur was determined with plasma emission spectroscopy and with an indirect AAS method. The determination from CaCl2 extracts was also made turbidimetrically and from AAAc extracts gravimetrically. The results were compared with the yield and uptake of sulphur by Italian ryegrass in a pot experiment. AAAc extracted 1/4-1/2 more sulphur than did CaCl2 solution. From both extracts plasma emission spectroscopy yielded considerably higher results than other methods. The amounts of sulphur determined with various methods correlated well with the grass yields (r=0.77∗∗∗-0.87∗∗∗) and plant uptake of sulphur (r=0.81∗∗∗-0.91∗∗∗). The exception, however, were the gravimetric measurements, which were not in agreement with the results of the pot experiment. The determination made with plasma emission spectroscopy produced as practicable results as the mor...

OBJECTIVES The possible adverse respiratory effects of airborne pollutants in sawmills have not been thoroughly investigated in Iran. Additionally, the extent to which workers are exposed to this organic dust and its associated bioaerosols has not been extensively quantified. Likewise, the predominant bacterial and fungal species associated with wood dust have not been characterized. The present study was undertaken to address these issues. METHODS One hundred male individuals exposed to wood dust and 100 unexposed male subjects were investigated. They completed a standardized respiratory symptom questionnaire and underwent spirometry testing. Additionally, airborne concentrations of respirable and inhalable dust particles, bacteria, and fungi were measured. RESULTS The mean concentrations of inhalable and respirable dust particles, bacteria, and fungi were found to be 2.44, 6.76 mg/m3 , 756.38, and 299.15 colony-forming units/m3 , respectively. The predominant Gram-negative bacteria in the sawmills included the Pseudomonadaceae, Klebsiella pneumoniae, and Rhinoscleromatis spp., and the predominant fungi consisted of the zygomycetes and Aspergillus spp. Respiratory symptoms were significantly more prevalent among exposed workers. Significant cross-shift decrements were noted in some pulmonary function parameters. Similarly, pre-shift spirometry results indicated that some pulmonary function parameters were significantly lower in the exposed group. CONCLUSIONS Exposure to wood dust and its bioaerosols was associated with significantly higher prevalence of respiratory symptoms and both acute (i.e., partially reversible) and chronic (i.e., irreversible) decrements in the functional capacity of the lung. Additionally, the characterized bioaerosols did not differ significantly from those isolated in other parts of the world.

Male populations in the European North of Russia have not previously been investigated for semen quality. The aim of this study was to evaluate semen parameters, reproductive hormone levels, and lipid levels in volunteers from the general urban population of the European North of Russia, to compare the data published for men from the neighboring Northern or Eastern European countries, and to evaluate associations between sperm quality and serum hormonal and lipid levels. Ninety-nine volunteers aged 23–63 years residing in the city of Archangelsk were enrolled in the study. All men had blood samples drawn and completed a questionnaire concerning their health status and lifestyle; 90 men delivered semen samples. The medians for semen volume, sperm concentration, progressive motility, and normal morphology were 3.0 ml, 42.12 million/ml, 43.8%, and 6.5%, respectively. Sperm parameters below normal threshold values were found in 38.9% of participants. It seems that the sperm quality in our study group was slightly worse than in men from Finland, Norway, Sweden, or Estonia, but very similar to that in men from Denmark or Poland. The significant negative correlations of luteinizing hormone levels and positive correlations of inhibin B levels with sperm concentration and progressive motility were revealed. Higher levels of luteinizing hormone and lower levels of inhibin B were found in participants with impaired compared to normal sperm quality. No reliable links were found between serum total cholesterol, triglyceride, high and low-density lipoprotein cholesterol, and semen parameters.

Superhydrophobic surfaces (SHS) show remarkable water repellency properties, and their use may have a tremendous impact for a plethora of applications, where liquid water accumulation needs to be controlled or minimised. However, the durability of SHS in operational conditions is a severe issue that currently represents a bottleneck for the technology transfer from laboratory to industrial applications. In the present work, we try to fill in the gap caused by the absence of a standard for evaluation for SHS durability, by developing a protocol for testing surface durability. The proposed protocol includes nine tests as follows: water immersion, acidic environment, alkaline environment, ionic solution, mechanical erosion, ultraviolet exposure, resistance to heating, alcohol immersion and hydrocarbon immersion. The protocol can serve to give an indication of surface robustness in a variety of potentially harmful environments, by providing a global figure of merit and ranking for different SHS and thereby al...

Radiotherapy is one of the most effective treatments for head and neck cancer. However, in addition to the target tumor, normal salivary glands are also included in the irradiation field. This unavoidably results in dry mouth syndrome as a side effect. In this study, the protective efficacy of basic fibroblast growth factor (bFGF) was investigated in radiation‐damaged salivary glands.

One component of active power filters is the controller, whose design can determine the overall performance of the filter. Among different active filters control strategies, there is one configuration with generally accepted good performance: the harmonic controller. Its robustness against the measurements is evaluated in this paper for two different implementations. The overall performance of the control section of the active filter is analyzed taking into account the current and voltage measurement uncertainties For comparison purposes, the classical PI controller is also analyzed. Based on numerical simulation data, it is concluded that for similar active filter design, the control method based on harmonic controllers implemented on the synchronous referential is more appropriate.

Damage to property and (or) non-property rights of persons occurs quite often. The right to compensation for such damage is indisputable. However, civil doctrine ambiguously addresses the issue of risk sharing in tort obligations. Therefore, the purpose of this paper is to discuss approaches to the distribution of risk of harm in delictual responsibility and to determine their effectiveness from an economic and legal standpoint. The paper, based on economic and systematic analysis using dialectical, comparative, logical-dogmatic and other methods, including economics, describes the approaches to determining the purpose of tort law and its ability to ensure effective distribution of risk of harm. It has been proven that tort law can have direct regulatory consequences by restraining behaviour and sharing risks. It is concluded that the task of tort law is the optimal distribution of risk of harm between the perpetrator and the victim and to ensure the implementation of risky activities only if its social value justifies the risk. Based on the economic analysis of tort law, it has been substantiated that the distribution of the risk of damage in tort liability is carried out through the institutions of insurance and liability. Insurance is cost-effective when it comes to compensation for damage. However, only liability, in addition to the function of compensation, can also perform the function of preliminary prevention of harm. Therefore, the risk of causing harm in tort liability is mainly borne by the person who caused the damage. In obligations to compensate for damage caused by a source of increased danger, a person who on the appropriate legal basis (property rights, other property rights, contracts, leases, etc.) owns a vehicle, mechanism, other object, the use, storage or maintenance of which creates an increased danger, bears such risk even in the absence of guilt in causing harm. The grounds for imposing such risk on the victim are his intention or force majeure. It is this approach to the distribution of harm risk in tort liability that is fair and cost-effective and contributes to public well-being

Lactate dehydrogenase (LDH) has been reported to be associated with outcomes after surgery in patients with aneurysmal subarachnoid hemorrhage (aSAH), but it is unclear if this is independent from other biomarkers and across all aSAH treatments. This study aims to assess whether LDH is an independent predictor of mortality in patients with aSAH and test whether the inclusion of LDH in a well‐established prediction model can improve discrimination and reclassification.

Abstract: Static tests with various in‐plane loads from 0 to 30 kN were conducted, to study in‐ plane load effects on the static behaviour of CFRP laminated composite panels when subjected to transverse load. The panels were 32 ply with the unidirectional carbon epoxy plies in a quasi‐isotropic lay up. It is shown that panel stiffness and maximum load increase with increasing in‐plane load and that a failure mode transition occurs with increasing in‐plane load. It is also shown that the energy absorbed by the panel to failure is approximately constant with respect to in‐plane load. Experimental information on load v deflection histories, surface strain histories and different failure modes together with material properties are presented in the paper, which could be used for analytical and numerical simulations of the problem.

Induction of hereditary changes by grafting in tomato was reconfirmed by combination of the cultivar Jubilee (yellow skin-orange flesh) as scion and the cultivar Tiny Tim (yellow skin-red flesh) as stock.The phenotypic change from yellow-orange (Jubilee type) to yellow-red (Tiny Tim type) was observed in the grafted scion (G0) on the Tiny Tim stock. In the selfed progeny (G1) from this Tiny Tim type variant fruit on the Jubilee scion, new type (colorless-red) was segregated in addition to Jubilee type (yellow-orange) and Tiny Tim type (yellow-red). The genotypic change of skin and flesh color is assumed to have occurred from Yyrr (yellow-orange) to YyRr (yellow-red) in the grafted scion and in the first self ed progeny, Y-R-(yellow-red), Y-rr (yellow-orange) and yyR-(colorless-red) were segregated from the YyRr variant (G0). Most of the successive progenies (G2 and G3) obtained from the segregants in the G1 generation accorded with Mendelian inheritance. But the phenotypic changes inexplicable in terms of Mendelism were assumed to have changed from yyR-(G1) to Y-R-(G2), from Y-rr (G2) to Y-R-(G3) and from yyR-(G2) to Y-R-(G3). But yyrr (colorless-orange) was not detected in all successive progenies. No other characters than skin and flesh color have been changed in the present study.It is likely to suppose that the transmission of genetic material from stock to scion would have occurred, though the mechanism is quite obscure yet.

Abstract: This presentation deals with the molecular substrates of the inherited diseases leading to genetically determined cardiac arrhythmias and sudden death. In the first part of this article the current knowledge concerning the molecular basis of cardiac arrhythmias will be summarized. Second, we will discuss the most recent evidence showing that the picture of the molecular bases of cardiac arrhythmias is becoming progressively more complex. Thanks to the contribution of molecular genetics, the genetic bases, pathogenesis, and genotype‐phenotype correlation of diseases—such as the long QT syndrome, the Brugada syndrome, progressive cardiac conduction defect (Lenegre disease), catecholaminergic polymorphic ventricular tachycardia, and Andersen syndrome—have been progressively unveiled and shown to have an extremely high degree of genetic heterogeneity. The evidence supporting this concept is outlined, with particular emphasis on the growing complexity of the molecular pathways that may lead to arrhythmias and sudden death, in terms of the relationships between genetic defect(s) and genotype(s), as well as gene‐to‐gene interactions. The current knowledge is reviewed, focusing on the evidence that a single clinical phenotype may be caused by different genetic substrates and, conversely, a single gene may cause very different phenotypes acting through different pathways.

This paper presents a new DOT coding scheme prioritized DOT (PDCT). This scheme uses partition priority coding 8 to perform PDCT. PPC encodes DOT coefficients in the order of their (absolute) magnitude in favor of the larger coefficients without coding overhead for position information. This results in an adaptive and progressive image coding. Different from classical DOT image coding this scheme does not use any bit allocations and quantization except integer rounding. Instead this scheme utilizes multiple distribution entropy coding (MDEO). This leads to an efficient coding for progressive image transmission or compression. For PDOT an image undergoes a 8x8 or 16x16 block DOT transform and the DOT coefficients are rounded to c-bit (typically 8 bit) precision. Using PPO the coefficients on the entire image are adaptively coded. That is the largest (i. e. the most significant) coefficients are coded first followed by the smaller ones until a given bit rate is reached. Using MDEO the values and position information (required by PPO) of the ordered coefficients are packed efficiently. The PDCT coding method is shown significantly better than current lossy compression methods in (1) SNR for a given bit rate (2) Adaptivity for images other than the " class" for which the method was originally tuned and (3) Early recognition of images when used in progressive image transmission. Typical SNR results are 30. 9 dB 34. 0 dB and 36.

The New Deal for Lone Parents is one policy in the UK which aims to reduce benefit dependency and enable lone parents to opt into a scheme which offers help and advice on jobs, benefits, training and childcare with the hope of improving job readiness. In tandem with this scheme there exists a myriad of community intervention initiatives whose aim may not be as explicit, but whose value can be equally empowering in raising self-awareness and self-esteem. This study examines the experiences of lone parents who participate in such schemes and contrasts this with the experiences of those who do not. The study shows that community-based schemes may not offer the best option for all lone mothers, but can provide an effective staging post for some towards a position of job readiness. Poverty and social exclusion affect many different aspects of people's lives. They exist when people are denied opportunities to work, to learn, to live healthy, active and fulfilling lives … Department of Social Security, September 1999, p. 3

Existing level-wise spatial co-location algorithms suffer from generating extra, non-clique candidate instances and thus requires cliqueness checking at every level. In this paper, we propose a novel, spatial co-location mining algorithm which automatically generates co-located spatial features without generating any non-clique candidates at any level. Subsequently our algorithm generates less candidates than other existing level-wise co-location algorithms without losing any information. The benefit of our algorithm has been clearly observed at an earlier stage in the mining process.

Abstract This paper explains how a permissive planning permit system is embedded in Belgian/Flemish society and how this contributes to urban sprawl. We base our analysis on an institutionalist approach as developed in previous and current research and analyse the Flemish planning permit system since 1962 as one of different interacting planning systems, all (re)produced, maintained, transformed and struggled over by specific individual and collective actors and shaped by a range of institutional dynamics. The analysis shows how in the dynamics of the Flemish planning permit system, a general struggle between actors defending property-based private initiative and actors arguing for collective action in space is especially apparent. In this struggle, property ownership expressed through a permissive planning permit system and limited enforcement of regulations is seen to be predominant, especially in the 1960s, 1980s and 2000s. Changes in the 1990s, making the planning permit system more strict, have partly and momentarily challenged the institutional frame which structures the predominant planning permit practice, but left the logic of individual property largely untouched. Today, the Flemish planning permit system has again been reoriented towards the protection of private property, which hampers the capacity of government to implement a coherent spatial policy.

Food-based dietary guidelines (FBDGs) offer recommendations that help population to meet nutrient requirements. Most European FBDGs include quantitative information regarding daily and weekly consumed foods, but for occasionally consumed foods, they only recommend limiting their intake, without giving specific advice on portions. As these foods are consumed by the general population as a part of the cultural and culinary tradition of each country, it is important to establish the maximum frequency and the portions that would be acceptable to be included in a healthy eating pattern. This study outlines the methodology to include these foods in a national (Spanish) FBDG. Firstly, commonly consumed foods were selected and grouped, and portions were defined according to their nutritional value, so different foods within a group could be exchanged. Then, macronutrient profiles of occasionally consumed foods were compared to the frequently consumed food groups to determine to what extent they had a similar nutritional content. Finally, some combinations of foods, with or without the inclusion of occasionally consumed groups, were calculated. A maximum number of servings per group was defined according to their energy and nutrient content. Occasionally consumed foods can be included in a healthy diet as long as they are consumed in the small quantities as shown in this study and as long as they replace equivalent portions of other foods of frequent consumption. This new tool shows how to include occasionally consumed foods in a diet while maintaining its overall nutritional quality.

The measuring data produced by pipeline detector should be first stored then processed and analyzed before being applied in analysis of pipeline defects. The results are commonly expressed in form of graphs so that it is unable to give constant and intuitive display of pipeline defects. According to such situation, it aims at developing the visualization system which can be used in computer to simulate and give real-time display of pipeline’s detection situation, receive and deal with test data sent by the pipeline detector during its operation process, generate and display the simulated three-dimensional pipeline in order to help analysis of pipe wall. The practical application indicates that the system has the characteristics of instantaneity, authenticity, and validity etc., being able to provide demonstrations and reference for construction of other pipeline real-time visualization system.

Propagation of plasma waves in degenerate electron systems is considered. A modified dispersion equation for plasma waves is derived by taking into account the influence of random impurities without using perturbation theory. The damping of plasma waves is calculated for the T = 0 limit. It is shown that the damping is non-zero in long wavelength limit due to the random impurities.
Die Ausbreitung von Plasma-Wellen in entarteten Elektronensystemen wird untersucht. Ohne Verwendung der Storungstheorie wird durch Berucksichtigung des Einflusses von statistisch verteilten Storstellen eine modifizierte Dispersionsrelation fur Plasma-Wellen hergeleitet. Die Dampfung von Plasma-Wellen wird fur den Grenzfall T = 0 berechnet. Es wird gezeigt, das die Dampfung im Grenzfall groser Wellenlangen aufgrund der statistisch verteilten Storstellen nicht verschwindet.

Abstract INTRODUCTION THE presence of chlorinated hydrocarbon pesticide residues in poultry and eggs has been reported by Ivey et al. (1961), Ware and Naber (1961), Onley and Mills (1962), J. J. Haberman (1964), Liska et al. (1964a, b) and Stemp et al. (1964). Detection and identification of these residues involve tedious product examination that ordinarily requires sophisticated laboratory equipment. The procedures are so time consuming that they preclude extensive surveys of poultry and eggs entering marketing channels. Ivey et al. (1961) determined lindane residues in chickens and eggs using the colorimetric method of Schechter and Hornstein (1952). Ware and Naber (1961) also determined lindane in eggs but used the colorimetric method as modified by Wylegala et al. (1956) and Ware and Gilmore (1959). Onley and Mills (1962) described a Florisil column chromatographic method for cleanup prior to pesticide detection in eggs using paper chromatography. They preceded the use of the Florisil …

How does a gravitational field produce a force?Why areinertial mass and gravitationalmass the same? It appears that all three ofthese seemingly axiomaticfoundational questions have an answer involving an identical physical process: interaction between theelectromagnetic quantum vacuum and the fundamental charged particles (quarks and electrons) constitutingmatter. All three of these effects and equalities can be traced back to the appearance of a specific asymmetryin the otherwise uniform and isotropic electromagnetic quantum vacuum. This asymmetry gives rise to anon-zero Poynting vector from the perspective of an accelerating object. We call the resulting energy-momentum flux the Rindler flux. The key insight is that the asymmetry in an accelerating reference framein flat spacetime is identical to that in a stationary reference frame (one that is not falling) in curvedspacetime. Therefore the same Rindler flux that creates inertial reaction forces also creates weight. Allof this is consistent with the conceptualizaton and formalism of general relativity. What this view addsto physics is insight into a specific physical process creating identical inertial and gravitational forces fromwhich springs the weak principle of equivalence. What this view hints at in terms of advanced propulsiontechnology is the possibility that by locally modifying either the electromagnetic quantum vacuum and/orits interaction with matter, inertial and gravitational forces could be modified.INTRODUCTIONWhy does F equal ma in Newton’s equation of motion, F= ma?How does a gravitational field produce a force?Why are inertial mass and gravitational mass the same?These are questions that are usually thought to be more appropriate for philosophers than for physicists,since the apparent facts of nature addressed in these questions are generally regarded as axiomatic.[1] If oneassumes that one plus one equals two, plus a limited number of additional axioms, one can develop a self-consistent system of mathematics, but one has to start with such assumptions. In the realm of geometry,the discovery of non-Euclidean geometry in the 19th century taught us that other, non-intuitive assumptionsare possible, and indeed, Riemannian geometry became the basis for physics in Einstein’s general relativity(GR). Alternate foundational assumptions can lead to new insights.Since 1991 we have been engaged in investigations involving the nature of inertia based on the founda-tional assumption that the electromagnetic quantum vacuum, also called the zero-point field or zero-point1
