Studies on Thermal structure in the seas around in India

The thesis entitled Studies on Thermal Structure in the Seas Around India. An attempt is made in this study to document the observed variability of thermal structure, both on seasonal and short-term scales, in the eastern Arabian Sea and southwestern Bay of Bengal, from the spatial and time series data sets from a reasonably strong data base. The present study has certain limitations. The mean temperatures are based on an uneven distribution of data in space and time. Some of the areas, although having a ‘full annual coverage, do not have adequate data for some months. Some portions in the area under study are having data gaps. The consistency and the coherence in the internal wave characteristics could not be examined due to non-availability of adequate data sets. The influence of generating mechanisms; other than winds and tides on the observed internal wave fields could not be ascertained due to lack of data. However, a comprehensive and intensive data collection can overcome these limitations. The deployment of moored buoys with arrays of sensors at different depths at some important locations for about 5 to 10 years can provide intensive and extensive data sets. This strong data base can afford to address the short-term and seasonal variability of thermal field and understand in detail the individual and collective influences of various physical and dynamical mechanisms responsible for such variability.

3000 / futuristische Phantasmen und aktuelle Fantasien der Technokultur

Die Kernthese dieser Arbeit ist eine Leerstelle. Ihre Formulierung beruht auf einer Beobachtung, wie sie von William Gibson stammen könnte: kulturell avantgardistische Gruppen der Gesellschaft internalisieren für ihre technologisch gestützten Praktiken futuristische Phantasmen geschichtlicher Vorläufer, die in Literatur und Mediengeschichte detektivisch aufspürbar sind. Werden diese Verinnerlichungen in aktuelle Fantasien umgewandelt, entsteht eine hybride Mischung vielfältigster Beschäftigungen, Reflexionen und Entwürfe von Technokultur. Bringt man diese Kopplungen auf das Jahr 3000, die nächste epochale zukünftige Zäsur, wird die Absurdität des Projekts, Technokultur überhaupt zu thematisieren deutlich. Technokultur ist im dynamischen Wandel sozio-ikonografisch untersuchbar, wird aber durch Unschärferelation zum object trouvé und Triebmoment für eine in es selbst hinein assimilierbare Analyse. Der daraus folgenden Vermessenheit kann durch instrumentelle Serendipity begegnet werden, die hier nicht Effekt wäre, stattdessen als Methode Verwendung findet: Finden statt Suchen. Das verhältnismäßig neue Schreib/Lese-Medium Hypertext bietet sich dafür als geradezu prädestiniert an. Hypertext ist prinzipiell unabgeschlossen, er folgt hier Arbeitsprinzipien wie sie seit den frühen 1990ern in Online-Tagebüchern und seit den frühen 2000er Jahren in Weblogs (World Wide Web Logbooks) auszumachen sind: Notizen, Found Text (analog zu Found Footage), Zitate, Fragmente, die kurze Form, kurz: wissenschaftliche Alltagstextproduktion wird nach Ordnungskriterien a-systematisiert und verwoben - weniger archiviert denn gesammelt. Eine Art Second Hand Theorie entsteht.

Application of the european customer satisfaction index to postal services. Structural equation models versus partial least squars

Customer satisfaction and retention are key issues for organizations in today’s competitive market place. As such, much research and revenue has been invested in developing accurate ways of assessing consumer satisfaction at both the macro (national) and micro (organizational) level, facilitating comparisons in performance both within and between industries. Since the instigation of the national customer satisfaction indices (CSI), partial least squares (PLS) has been used to estimate the CSI models in preference to structural equation models (SEM) because they do not rely on strict assumptions about the data. However, this choice was based upon some misconceptions about the use of SEM’s and does not take into consideration more recent advances in SEM, including estimation methods that are robust to non-normality and missing data. In this paper, both SEM and PLS approaches were compared by evaluating perceptions of the Isle of Man Post Office Products and Customer service using a CSI format. The new robust SEM procedures were found to be advantageous over PLS. Product quality was found to be the only driver of customer satisfaction, while image and satisfaction were the only predictors of loyalty, thus arguing for the specificity of postal services

WAIS Seminar: Research Discussion: Open Data at the Hampshire Hub

This is a research discussion about the Hampshire Hub - see http://protohub.net/. The aim is to find out more about the project, and discuss future collaboration and sharing of ideas. Mark Braggins (Hampshire Hub Partnership) will introduce the Hampshire Hub programme, setting out its main objectives, work done to-date, next steps including the Hampshire data store (which will use the PublishMyData linked data platform), and opportunities for University of Southampton to engage with the programme , including the forthcoming Hampshire Hackathons Bill Roberts (Swirrl) will give an overview of the PublishMyData platform, and how it will help deliver the objectives of the Hampshire Hub. He will detail some of the new functionality being added to the platform Steve Peters (DCLG Open Data Communities) will focus on developing a web of data that blends and combines local and national data sources around localities, and common topics/themes. This will include observations on the potential employing emerging new, big data sources to help deliver more effective, better targeted public services. Steve will illustrate this with practical examples of DCLG’s work to publish its own data in a SPARQL end-point, so that it can be used over the web alongside related 3rd party sources. He will share examples of some of the practical challenges, particularly around querying and re-using geographic LinkedData in a federated world of SPARQL end-point.

Efectos en los grandes procesadores lecheros colombianos con la entrada en vigencia del tratado de libre comercio con la unión europea

La economía mundial ha presentado una tendencia hacia la globalización y la integración económica; este comportamiento ha influenciado significativamente la economía Colombiana en los últimos años, promoviendo los lazos comerciales con diferentes economías a nivel mundial; esto con el objetivo de fortalecer la actividad económica tanto interna como externamente, buscando nuevas oportunidades que le permitan un crecimiento económico perdurable, a través de la inversión extranjera directa, la investigación y desarrollo, innovación tecnológica, mano de obra calificada, entre otros. Continuando esta tendencia Colombia inició un proceso de negociación de un Tratado de Libre Comercio con la Unión Europea en el año 2012, el cual culminó con éxito firmándose el 31 de Julio del 2013, mediante el decreto 1636, donde Colombia y la Unión Europea por libre albedrio se comprometieron a cumplir con todos los puntos pactados dentro del tratado. Con el objetivo de generar un diagnóstico del sub-sector lechero, se analizó la situación actual de la economía Colombiana frente a la Unión Europea, vista desde la productividad y la competitividad que se presenta en cada una de estas economías, para determinar las oportunidades o las amenazas que podría representar el tratado de libre comercio con dicho grupo económico pero específicamente concentrándose en la industria procesadora de productos lácteos. Del diagnóstico comparativo se encontró que existen grandes asimetrías entre la industria procesadora de productos lácteos en Colombia frente a la misma de la Unión Europea (UE). Por último se realizó el análisis de los factores internos de las empresas a través de la Matriz de Evaluación de Factores Internos (MEFI), indicador que permite identificar la debilidad o fortaleza dentro de las empresas de acuerdo a la valoración de las características de cada una. Por otro lado, a través de la matriz DOFA se analizaron las debilidades, oportunidades, fortalezas y amenazas de las empresas; de acuerdo a los resultados de ambas matrices se plantearon recomendaciones que podrán ser aplicadas dentro de las empresas objeto de estudio.

Impacto do excesso de peso sobre a fisiologia normal da pele humana in vivo

A obesidade é um problema de saúde pública com prevalência crescente, nomeadamente em Portugal, onde mais de 50% da população é obesa. As consequências fisiopatológicas do peso excessivo têm grande impacto a nível cutâneo. Contudo, existem ainda poucos estudos sobre a fisiologia cutânea, não existindo qualquer estratificação destas alterações em função do peso corporal. O presente estudo pretende contribuir para o estudo das alterações ao nível da hidratação e comportamento biomecânico com o aumento de peso. Este estudo transversal foi efetuado numa amostra de conveniência de 57 voluntárias, do sexo feminino, com idades compreendidas entre os 20 e os 46 (30±8) anos. As voluntárias foram divididas em dois grupos - Grupo I, com IMC entre 19,9 e 24,9 Kg/m2 e Grupo II, entre 25 e 29,9 Kg/m2. Foi efetuada uma única determinação da hidratação superficial, perda transepidérmica de água e comportamento biomecânico da pele (métodos não-invasivos). Os dados obtidos permitem-nos verificar que o aumento de peso influencia positivamente os níveis de hidratação e perda transepidérmica de água e de forma negativa o comportamento biomecânico da pele. Apesar do interesse destes resultados torna-se necessário realizar mais estudos, com maior número de indivíduos, de forma a melhor esclarecer a sua natureza e significado.

Jpowder: a Java-based program for the display and examination of powder diffraction data

The ability to display and inspect powder diffraction data quickly and efficiently is a central part of the data analysis process. Whilst many computer programs are capable of displaying powder data, their focus is typically on advanced operations such as structure solution or Rietveld refinement. This article describes a lightweight software package, Jpowder, whose focus is fast and convenient visualization and comparison of powder data sets in a variety of formats from computers with network access. Jpowder is written in Java and uses its associated Web Start technology to allow ‘single-click deployment’ from a web page, http://www.jpowder.org. Jpowder is open source, free and available for use by anyone.

Low-order dynamical behavior in the martian atmosphere: Diagnosis of general circulation model results

The hypothesis of a low dimensional martian climate attractor is investigated by the application of the proper orthogonal decomposition (POD) to a simulation of martian atmospheric circulation using the UK Mars general circulation model (UK-MGCM). In this article we focus on a time series of the interval between autumn and winter in the northern hemisphere, when baroclinic activity is intense. The POD is a statistical technique that allows the attribution of total energy (TE) to particular structures embedded in the UK-MGCM time-evolving circulation. These structures are called empirical orthogonal functions (EOFs). Ordering the EOFs according to their associated energy content, we were able to determine the necessary number to account for a chosen amount of atmospheric TE. We show that for Mars a large fraction of TE is explained by just a few EOFs (with 90% TE in 23 EOFs), which apparently support the initial hypothesis. We also show that the resulting EOFs represent classical types of atmospheric motion, such as thermal tides and transient waves. Thus, POD is shown to be an efficient method for the identification of different classes of atmospheric modes. It also provides insight into the non-linear interaction of these modes.

Phytocannabinoids as novel therapeutic agents in CNS disorders

The Cannabis sativa herb contains over 100 phytocannabinoid (pCB) compounds and has been used for thousands of years for both recreational and medicinal purposes. In the past two decades, characterisation of the body's endogenous cannabinoid (CB) (endocannabinoid, eCB) system (ECS) has highlighted activation of central CB1 receptors by the major pCB, Δ9-tetrahydrocannabinol (Δ9-THC) as the primary mediator of the psychoactive, hyperphagic and some of the potentially therapeutic properties of ingested cannabis. Whilst Δ9-THC is the most prevalent and widely studied pCB, it is also the predominant psychotropic component of cannabis, a property that likely limits its widespread therapeutic use as an isolated agent. In this regard, research focus has recently widened to include other pCBs including cannabidiol (CBD), cannabigerol (CBG), Δ9tetrahydrocannabivarin (Δ9-THCV) and cannabidivarin (CBDV), some of which show potential as therapeutic agents in preclinical models of CNS disease. Moreover, it is becoming evident that these non-Δ9-THC pCBs act at a wide range of pharmacological targets, not solely limited to CB receptors. Disorders that could be targeted include epilepsy, neurodegenerative diseases, affective disorders and the central modulation of feeding behaviour. Here, we review pCB effects in preclinical models of CNS disease and, where available, clinical trial data that support therapeutic effects. Such developments may soon yield the first non-Δ9-THC pCB-based medicines.

Measuring the discrepancy between fecundity and lifetime reproductive success in a pollinating fig wasp

Lifetime reproductive success in female insects is often egg- or time-limited. For instance in pro-ovigenic species, when oviposition sites are abundant, females may quickly become devoid of eggs. Conversely, in the absence of suitable oviposition sites, females may die before laying all of their eggs. In pollinating fig wasps (Hymenoptera: Agaonidae), each species has an obligate mutualism with its host fig tree species [Ficus spp. (Moraceae)]. These pro-ovigenic wasps oviposit in individual ovaries within the inflorescences of monoecious Ficus (syconia, or ‘figs’), which contain many flowers. Each female flower can thus become a seed or be converted into a wasp gall. The mystery is that the wasps never oviposit in all fig ovaries, even when a fig contains enough wasp females with enough eggs to do so. The failure of all wasps to translate all of their eggs into offspring clearly contributes to mutualism persistence, but the underlying causal mechanisms are unclear. We found in an undescribed Brazilian Pegoscapus wasp population that the lifetime reproductive success of lone foundresses was relatively unaffected by constraints on oviposition. The number of offspring produced by lone foundresses experimentally introduced into receptive figs was generally lower than the numbers of eggs carried, despite the fact that the wasps were able to lay all or most of their eggs. Because we excluded any effects of intraspecific competitors and parasitic non-pollinating wasps, our data suggest that some pollinators produce few offspring because some of their eggs or larvae are unviable or are victims of plant defences.
