The discursive representation of host locations in a sports media event: Locating the ‘Real Site’ of Formula One
Authors: Evans Claire
Published: May 2014

Locations are often chosen to host major sporting events because of their world and economic status, whilst the hosting of a major sporting event further enhances the standing of a host-location on a global scale. The media play a central role in depicting the image and values of the host-destinations on display, but unlike other major sporting events, such as the World Cup or the Olympic Games that travel to a different destination every four years, the FIA Formula One World Championship travels to multiple worldwide destinations in the course of a season.  Live broadcasts routinely represent both traditional and modern Formula One venues to viewers; especially during programme openings, where they are aligned to: the local, unique characteristics of the destinations travelled to; the global ethos of the sport; and the media context itself.  Using illustrative examples from British broadcasts of Formula One, I explain why delineating the ‘core’ and ‘periphery’ of a sports media event is questionable, but although it throws doubt on our ability to pinpoint the ‘real site’ of a global sports event, it nevertheless illustrates the position that sports, host-locations and the media have as part of a global network.

Published: May 2014

Automedicação é o consumo de medicamentos não prescritos, onde o paciente decide qual substância usar. Essa prática pode provocar danos à saúde ou mascarar sintomas de doenças mais graves. O medicamento se tornou um elemento importante na recuperação e garantia da qualidade de vida; no entanto, há riscos evitáveis associados a seu uso que podem ser minimizados pela racionalização do consumo desses produtos. Os idosos consomem mais medicamentos que outros grupos etários, sendo mais suscetíveis ao uso irracional desses. Esse estudo objetivou identificar os determinantes associados à prática da automedicação em idosos da cidade de Barretos/São Paulo/Brasil. O estudo foi conduzido na zona urbana da cidade de Barretos-SP, e os questionários aplicados em uma amostra populacional de 122 indivíduos entre 60 anos ou mais. Os dados foram processados e analisados através das porcentagens. Do total (122 pacientes), 11,48% relataram utilizar apenas medicamentos prescritos e 88,52% consomem medicamentos sem prescrição. Os fármacos mais consumidos pelos idosos que praticam automedicação são os analgésicos e antipiréticos (76,23%). Dentre as justificativas apresentadas para a automedicação, cefaleia foi a mais frequente (66,69%), seguida por febre (61,48%). Esses achados sugerem falta de controle sobre a aquisição de medicamentos por idosos dessa região, favorecendo a ocorrência das consequências danosas da automedicação.
CICLO DA ASSISTÊNCIA FARMACÊUTICA E A ATUAÇÃO DO FARMACÊUTICO EM UNIDADES BÁSICAS DE SAÚDE DE SANTA MARIA - RS
Authors: BISCAHYNO Francieli Barchet , LIMBERGER Jane Beatriz
Published: May 2014

De acordo com o Consenso Brasileiro de Atenção Farmacêutica, a assistência farmacêutica é um conjunto de ações desenvolvidas pelo farmacêutico, e outros profissionais de saúde, voltadas à promoção, proteção e recuperação da saúde, tanto em nível individual como coletivo. Neste contexto, a atuação do profissional na assistência farmacêutica municipal perpassa as atividades envolvidas no ciclo da assistência farmacêutica, visando à contínua oferta de medicamentos de qualidade ao paciente. Este estudo visou avaliar a realidade da assistência farmacêutica no município de Santa Maria através da identificação de atores responsáveis pelos medicamentos nas Unidades Básicas de Saúde (UBSs) ou seja, dos profissionais da saúde que detém a responsabilidade pelas ações relativas ao medicamento nestes locais. Ficou evidente a importância do profissional farmacêutico para a qualificação das atividades envolvidas com o ciclo da assistência farmacêutica, bem como para seu controle e avaliação. A inclusão do profissional farmacêutico nas equipes de saúde ainda é um desafio a ser buscado e depende da conscientização dos gestores sobre a importância deste profissional para a melhoria da gestão de medicamentos e da qualidade de vida dos pacientes.

Published: May 2014

O uso de medicamentos na gestação e lactação sempre representou um desafio para os profissionais de saúde, uma vez que implica ação potencialmente danosa não apenas para a mulher, mas também para o concepto. A maioria dos fármacos administrados às mulheres grávidas atravessa a barreira placentária e expõe o embrião em desenvolvimento a seus efeitos farmacológicos, nas lactentes, podendo ocorrer a sua transferência para o leite materno. O objetivo do trabalho foi de analisar os riscos potenciais às mulheres, causados pela utilização dos fármacos comumente dispensados na cidade de Aimorés (MG), caso estes viessem a ser administrados em período de gestação e amamentação. Foram avaliados 21 medicamentos selecionados na cidade de Aimorés, tendo como base os mais dispensados entre as mulheres, identificados por meio de farmacêuticos de 10 farmácias municipais. Os medicamentos foram classificados de acordo com a categoria de risco da FDA (Food and Drug Administration). Dos fármacos estudados, 4,76% se enquadrou na categoria de risco A da FDA, na categoria B, 23,8%. Na C, 47,61% podem apresentar efeitos teratogênicos ou tóxicos para os embriões, enquanto na D foram identificados 19,04% fármacos que evidencia risco para os fetos humanos. Na categoria X, apenas 4,76% dos fármacos foram identificados. Observou-se que a maioria dos fármacos representa um risco considerável para o feto e o lactente caso a mãe utilize esses medicamentos durante o período de gestação e lactação. Constatou-se que o uso deve ser melhor monitorado pelos prescritores e a presença da intervenção farmacêutica na dispensação é de suma importância.

A exposição excessiva ao sol e sem proteção representa um dos maiores riscos para o desenvolvimento de tumores malignos. O uso de substâncias para proteger a pele, como os filtros solares, tem a atenção do mercado. O desenvolvimento de fotoprotetores com eficácia e segurança é obtido através do conhecimento de seus mecanismos de ação e formulações. Os filtros solares e fotoprotetores, além de proteger contra os raios ultravioletas, podem hidratar e rejuvenescer a pele. O estudo é uma revisão bibliográfica sobre filtros solares e fotoprotetores, com objetivos de revisar os fenômenos que envolvem os filtros solares, apresentar as classificações, o mecanismo de ação e os métodos de avaliação da proteção solar, e por fim, evidenciar a importância do uso do filtro solar na prevenção do fotoenvelhecimento e do câncer de pele. Ressalta-se que o uso de combinações como de filtros inorgânicos com orgânicos aumentam o espectro de proteção, permitindo maior FPS com redução do custo e a potência de reações irritantes. A associação de óxido de zinco com dióxido de titânio permite obter formulações com baixo potencial alergênico e irritante, podendo ser utilizada por indivíduos mais sensíveis. Estas combinações representam o avanço da tecnologia e possibilidades para novos produtos no mercado com segurança.
AVALIAÇÃO DA CAFEÍNA EM ASSOCIAÇÕES MEDICAMENTOSAS

Published: May 2014

A cafeína é uma metilxantina de origem natural consumida mundialmente em alimentos e em associações medicamentosas, porém seus efeitos bem como o seu mecanismo de ação não são bem definidos de acordo com a literatura. O objetivo deste trabalho foi avaliar os benefícios e riscos ligados à associação da cafeína em medicamentos, bem como fazer comparação das doses citadas pela literatura com as encontradas nos medicamentos mais comercializados e nos alimentos mais consumidos no cotidiano da população. Foi feito levantamento de trinta e cinco medicamentos associados à cafeína mais vendidos em uma farmácia comercial de dispensação. Observou-se que a cafeína está associada a três classes de medicamentos mais utilizadas pela população, classificados farmacologicamente como analgésicos, antiinflamatórios e miorrelaxantes, sendo que 69% da dispensação destes medicamentos estava associada a busca espontânea por parte dos pacientes, 91% dos medicamentos apresentavam dose sub-terapêutica conforme literatura e em 75% dos casos a dose contida era inferior a 50 mg, dose esta consumida em alimentos por pessoa/dia. Assim, conclui-se que o emprego da cafeína em medicamentos ainda necessita de comprovação científica sobre seus benefícios e de estudos que definam critérios semelhantes aos de medicamentos para o uso da cafeína.

Published: May 2014

Foi realizado um estudo quantitativo, observacional transversal. Os dados foram obtidos por meio de entrevista semiestruturada, orientada por roteiro previamente testado. Foram avaliadas: características do paciente, conhecimento sobre hipertensão arterial, tratamento e problemas relacionados aos medicamentos, e foi medida pressão arterial de cada participante. A amostra foi constituída de 97 pacientes. Os indivíduos com familiares que apresentavam hipertensão constituíram 91,8% da amostra. Verificou-se que 57,7% estavam com sobrepeso, 56,7% não adotava restrição de sal e 73,2% não fazia atividades físicas de nenhum tipo. Apenas 45,4% são cuidadosos quanto ao horário de uso dos medicamentos, 69,1% não faz acompanhamento médico freqüentemente, sendo a dificuldade de conseguir consulta o motivo principal, apontado por 42,3%. Observou-se que 44,3% não tem conhecimento das conseqüências da hipertensão e 27,8% não sabem sobre a cronicidade da doença. O tratamento medicamentoso de 58,8% foi a monoterapia. Uma vez que com a atenção farmacêutica pode-se ter melhores respostas ao tratamento da hipertensão arterial
sistêmica, os resultados de baixa adesão ao tratamento observados neste estudo nos possibilitaram uma análise crítica e reflexiva sobre a necessidade de intensificar o atendimento farmacêutico desta drogaria, e explicar aos usuários os benefícios e os riscos de seus medicamentos anti-hipertensivos, com a finalidade de conduzi-los a um estilo de vida mais saudável, eliminar ou controlar os riscos da HAS.

Os hospitais veterinários possuem características que os distinguem de hospitais humanos. No entanto, os princípios básicos de assepsia, desinfecção, esterilização e uso de antimicrobianos são semelhantes. O objetivo deste trabalho foi implementar uma Comissão de Controle de Infecção Hospitalar (CCIH), visando monitorar e diminuir os índices de Infecções Hospitalares (IH) e o desenvolvimento de cepas resistentes. A implementação da CCIH, bem como seus Procedimentos Operacionais Padrão (POP’s) ocorreram no período entre 02 de março a 30 de setembro de 2009, no Hospital Veterinário ‘Dr. Halim Atique’, em São José do Rio Preto – SP. As principais medidas executadas foram a utilização do álcool 70% na forma farmacêutica de gel e programa de treinamento de higienização correta das mãos. Adequação do uso do digluconato de clorexidina 2% para assepsia cirúrgica em substituição a polivinilpirrolidona-iodo 10%, por seu maior efeito residual. Outra medida foi à troca do glutaraldeído 2% por ácido peracético 35% para desinfecção e esterilização química de materiais, além da utilização e monitoramento dos métodos de esterilização em autoclaves por meio de controles químico e microbiológico. Apesar de não haver legislação vigente para as CCIHs em hospitais veterinários, essas medidas são ferramentas imprescindíveis para a redução das infecções, devendo ser executadas adequadamente e monitoradas.
The isomorphism problem for linear representations and their graphs The isomorphism problem for linear representations and their graphs
Authors: Cara P. , Rottey S. , Van de Voorde G.
Published: May 2014

A linear representation T*n(K) of a point set K is a point-line geometry, embedded in a projective space PG(n+1; q), where K is contained in a hyperplane. We put constraints on K which ensure that every automorphism of T*n(K) is induced by a collineation of the ambient projective space. This allows us to show that, under certain conditions, two linear representations T*n(K) and T*n(K′) are isomorphic if and only if the point sets K and K′ are PΓL-equivalent. We also deal with the slightly more general problem of isomorphic incidence graphs of linear representations. In the last part of this paper, we give an explicit description of the group of automorphisms of T*n(K) that are induced by collineations of PG(n + 1; q).
Human Nature and the Right to Coerce in Kant’s Doctrine of Right
Authors: Pinheiro Walla Alice
Published: May 2014

Abstract: This paper explores the alleged role of a conception of human nature for Kant’s justification of the duty to leave the state of nature and the related right to coerce others to enter the civil condition in the Doctrine of Right (1797). I criticise the interpretation put forward by Byrd and Hruschka, according to which Kant’s postulate of public right is a preventive measure based on a “presumption of badness” of human beings. Although this reading seems to be supported by § 42 of the Doctrine of Right, I shall argue that the paragraph neither offers a justification of why we have a duty to leave the state of nature, nor explains why individuals are allowed to coerce others to do so. I offer an alternative interpretation of § 42 by focusing on the difference between formal and material violations of right and argue that the rationale behind the postulate of public right is the idea that remaining in the state of nature is a formal violation of the concept of right. It is therefore not prudential reason that authorizes us to coerce others to enter the lawful condition.
Revolution Imagined: Cause Advocacy, Consumer Rights, and the Evolving Role of NGOs in Thailand
Authors: Munger Frank
Published: May 2014

This article describes the founding and evolution of a “Thai-style” NGO dedicated to consumer protection. Through a description of the NGO and the career of its founder, the article brings to light features of the evolution of NGO-based advocacy in Thailand from the student uprising in 1973 to the present. The legacy of the 1973 October Generation of activists continues to influence development of NGOs but new emphasis on rights has emerged since the era of constitutional reform in the 1990s. Many NGOs now make use of litigation to attempt to achieve social change, but litigation, like other long-standing methods of advocacy involving reliance on networks that penetrate government itself, reflect the particular opportunities and pathways for change opened by Thailand’s politics.

After-School Center-Based Care and Children’s Development
Authors: Felfe Christina , Zierow Larissa
Published: May 2014

What is the impact of after-school center-based care on the development of primary school-aged children? Answering this question is challenging due to non-random selection of children into after-school center-based care. We tackle this challenge using detailed data of the German Child Panel and employing a value-added method. While we do not find significant effects on average, our analysis provides evidence for beneficial returns to after-school center-based care attendance for more disadvantaged children. To be more precise, children of less educated mothers and low-income families benefit from attending after-school care centers in terms of their socio-behavioral development.

The effects of single and dual coded multimedia instructional methods on Chinese character learning
Authors: Wang Ling
Published: May 2014

This study investigated the effects of single and dual coded instructional methods using computer-based multimedia on Chinese character learning. 42 college students with no prior knowledge of Chinese language were randomly assigned to a single coded group (text-only and animation-only) and a dual coded group (animation plus text and animation plus narration) to learn 12 concrete (pictograph) Chinese characters and 12 abstract (ideograph) Chinese characters. The results showed there was a significant difference between the single coded and the dual coded instructional methods and there was also a main effect in the character type. In addition, the findings indicated that within the single coded group, there was a significant difference between two character types and a significant difference between two single coded methods with the animation-only method leading to better achievement score than the text-only method. For the dual coded group, the results revealed a significant difference between two character types as well and a significant difference between two dual coded methods with the animation plus narration method outperforming the animation plus text method.
The interface of linguistic difficulty and task type on the use of the Chinese ba construction by L2 learners
Authors: Gao Xiaoping
Published: May 2014

This study investigates the effects of linguistic difficulty and task type on the use of Chinese ba construction by second language learners. One hundred and ten adult learners completed four tasks orally (i.e., an oral production task prompted by video clips, an oral imitation task, a grammaticality judgement task and a correction task), as well as a background questionnaire and a one-on-one post-task interview. Twenty-two native speakers of Chinese served as baseline. Results demonstrate that the variable type of the Chinese ba construction which is subject to functional constraints is harder to learn than the obligatory type which is subject to obligatory syntactic constraints, and that the oral tasks were more challenging to perform than the metalinguistic tasks. The findings suggest that a series of factors including functional value and discourse context contribute to the linguistic difficulty of Chinese grammar features. The processing constraints of completing tasks and their interaction with linguistic characteristics explain the learning difficulty of the two types of the ba construction.

Authors: Nokka Marjaana , Repin Sergey
Published: May 2014

We derive computable bounds of deviations from the exact solution of the stationary Oseen problem. They are applied to approximations generated by the Uzawa iteration method. Also, we derive an advanced form of the estimate, which takes into account approximation errors arising due to discretization of the boundary value problem, generated by the main step of the Uzawa method. Numerical tests confirm our theoretical results and show practical applicability of the estimates.

Temperature Peak Analysis and Its Effect on Absorption Column for CO2 Capture Process at Different Operating Conditions
Authors: Rashid Harith , Hasan Nurul , Mohamad Nor M. Iskandar
Published: May 2014

The role of temperature is important in CO2 capture processes. Unfortunately, detailed analysis on the temperature profile of the absorption column is scarce in the literature. Important factors like CO2 capture capacity and corrosion rate directly depend on temperature of the column. Many side reactions such as solvent degradation, formation of stable salts, corrosion and reduction in CO2 capture are prominent at a higher temperature. This study reports a broad study on the temperature profile for CO2 capture process based on a detailed mathematical model, Kent–Eisenberg vapor–liquid equilibrium (VLE) model. This model is quite accurate in calculating CO2 capture for any specific operating condition. Results produced from Kent–Eisenberg VLE model are consistent with experimental data. This study reports temperature profiles of an absorption column for different operating conditions. Moreover, it was found that CO2 absorption is more effective at low and ambient temperatures than at high temperature confirmed by a peak temperature in all cases and in the lower section of the column, which is attributed to exothermic CO2 absorption in monoethanolamine. This temperature variation of the column will be helpful in designing CO2 capture plants.

Stable manifolds for holomorphic automorphisms

consequence, we get a sufficient condition for the
stable manifold of a point in a compact hyperbolic invariant
subset of a complex manifold to be biholomorphic to a complex Euclidean space. Our result
immediately implies previous theorems obtained
by Jonsson–Varolin and by Peters; in particular,
we prove (without using Oseledec's theory) that the stable manifold of any point where the negative
Lyapunov exponents are well-defined is biholomorphic to a complex Euclidean space. Our approach is based on the solution of a linear control problem
in spaces of subexponential sequences, and on careful estimates of the norm of the conjugacy operator by a lower triangular matrix on the space of k-homogeneous polynomial endomorphisms of ℂ

We discuss various results and questions around the Grothendieck period conjecture, which is a counterpart, concerning the de Rham–Betti realization of algebraic varieties over number fields, of the classical conjectures of Hodge and Tate. These results give new evidence towards the conjectures of Grothendieck and Kontsevich–Zagier concerning transcendence properties of the torsors of periods of varieties over number fields.

The Tartu Synthesis in Semiotics Today Viewed from America
Authors: Deely John
Published: May 2014

By the 20th century’s end, semiotics had definitively emerged as the most historically and theoretically proper name for the study of how signs work in human experience, both in its cultural dimensions and in its inevitable dependency upon the physical environment and universe, which extends far beyond cultural influence and which the very existence of culture presupposes. Probably the single most key figure, as it were, “presiding over” this emergence was the Hungarian-American Thomas A. Sebeok. But key to Sebeok’s weaving of the “semiotic web” of a global awareness of sign-action within the intellectual culture of the 21st century was his appreciation and integration within his vision and work of two key background figures, both associated with Tartu University, namely, Jakob von Uexküll and Juri Lotman. I would like to comment on how the heritage of these two figures have proved to be the foundation stones - in some ways more important even than the, so far, more widely recognized figures of Ferdinand de Saussure and Charles Peirce - for the future of semiotics within university life and intellectual life generally.
Figures of the Body and the Semiotics of Imprint: Semiotic Figures of the Body in the Humanities
Authors: Fontanille Jacques
Published: May 2014

Semiotics of the body consists essentially, in a current use, in gestural and mimo-gestural semiotics. At best, in an integrated semiotic approach, communicative gesture involved the construction of a syncretic expression plane, combined with verbal discourse. The body as conceived by psychoanalysts is, on the contrary, the source and the seat of energy itself (impulses), from which psychic instances feed their representations. The psychoanalytical body is thus both the source and the significant substance from which the semiotic actant may take form. In the phenomological conception developed by Merleau-Ponty, the proper body is that entity, the “vehicle of our being in the world”, which belongs both to “I” and to “the world for me”, which takes shape in perception, where the first (I) experienced the second (world for me). The phenomenological body seems at first sight an adjuvant, which turns out to be, for a second sight, the very principle of actantiality and intentionality. In a quick overview of the different “implicit semiotics” of the body in human sciences (psychoanalysis, theory of “I-skin”, contemporary cognitive science, psychology, etc.) it acquires a status of an actantial basis, because, as an actant, it is directly involved in the process of incorporation of agentivity and intentionality, and with two different and recurrent representations: one according to movement, and the other according to envelope. Forces and form, in short. We decide to name them (arbitrarily for now, but we’ll return to this point) the first “Me” and the second “Myself”. • “Me” is the referent instance, consisting both of sensitive matter and energy, the substrate and the dynamic bodymark for all figures and all enunciations. In short, it will be the “Me-flesh.” • “Myself ” is the body-in-construction, the living vehicle of intentionality and the interactions support, and therefore, particularly the support of confrontation with otherness; and, through these interactions, it provides the actant a patterned form through which it may be identified. In short, this is “Myself-envelope”. Then the paper may display a new typology of semiotic body figures. At each of these figures of the body, is a figure of movement. At each of them, is a figure of enunciative instances, that is to say for each of them a modality of the imprint and of its interpretation.
Vico’s Potential in Semiotics: The Imaginative Universal and its Bodily Roots
Authors: Raudla Tuuli
Published: May 2014

The aim of this article is to give an overview of the interpretations of Giambattista Vico’s ideas in the context of general and Tartu semiotics and to bring attention to the possible fruitful lines of research in Vichian semiotics yet to be explored. One of the essential notions of Vico’s opus magnum The New Science is that of the imaginative universal. It signifies a primordial class concept that is based on bodily experience. Imaginative universals are part of mythological, or in Vico’s terms poetic, thought. In Vico’s conception, imagination is an extension of bodily experience - being thus a kind of mediator between sensory perception and more abstract levels of human cognition. The article provides a brief account of Vico’s connection to semiotics, followed by an outline of the concept of the imaginative universal in Vico’s texts, focusing on the aspect of body-mind interrelations. Finally, it offers some preliminary observations about the similarities between Vico’s concept of the imaginative universal and the concept of primary metaphors in the works of George Lakoff and Mark Johnson.
Expansions and asymptotics associated with basic hypergeometric functions and modified
q-Bessel functions
Authors: Salem Ahmed
Published: May 2014

In this paper, the expansion of a basic confluent hypergeometric function in terms of an incomplete q-gamma function is investigated and shown to be an asymptotic expansion for a basic confluent hypergeometric function and a q-analogue of the Hadamard expansion. The general expansion associated with a basic hypergeometric function is introduced. In special cases, this provides alternative derivations of the q-Hadamard expansion. Expansions and asymptotics for modified q-Bessel functions are derived as special cases from the general expansion.
Appearance, corrosion properties, and leach resistance of spruce and pine wood treated with Mea modified micronized copper preservative (MCu)
Authors: Lee Myung Jae , Pankras Sedric , Cooper Paul
Published: May 2014

Canadian refractory wood species treated with micronized copper (MCu) wood preservative become mottled and streaky in appearance. To overcome this issue, the MCu system was modified by adding small amounts of monoethanolamine (Mea). The modified systems were evaluated to clarify the role of Mea in terms of leaching, corrosion, and mold resistance of MCu systems. The mottled and streaky surface on treated spruce was prevented at Mea/Cu molar ratios between 0.7 and 1.5. Copper leaching remained modest and was only slightly higher than that of MCu alone up to a Mea/Cu molar ratio of 1.2. However, adding even a small amount of Mea to the MCu formulation increased fastener corrosion compared with MCu. Protonated Mea increased as more Mea was added and was identified as the main corrosion-causing electrolyte in the system.
Tensile behaviour and fracture mechanism of moso bamboo (Phyllostachys pubescens)
Authors: Liu Huanrong , Jiang Zehui , Fei Benhua , Hse Chungyun , Sun Zhengjun
Published: May 2014

The present work is aiming at the elucidation of the tensile behaviour and fracture performance of moso bamboo (Phyllostachys pubescens Mazei ex H. de Lebaie) by means of digital speckle correlation method (DSCM) and microscopic techniques. Results indicated that fibres play a major role in longitudinal tension and impeding crack radial propagation. Hybrid I-II failure mode was observed, i.e., crack opening (in tensile stress) and shear sliding (in shear stress). According to microscopic fracture characteristics, fibres extraction and stretching, filament formation in parenchyma with fibres bridging, interface debonding and the helix fracture of fibres happened in tension, which created more interfaces and dissipated more energy. The graded composite structure of bamboo provides intrinsic and extrinsic toughening mechanisms which contribute to improved toughness and physical properties.

The Influence of Yttrium on High Temperature Oxidation of Valve Steels
Authors: Grzesik Z. , Migdalska M. , Mrowec S.
Published: May 2014

The influence of small amounts of yttrium, electrochemically deposited on the surface of four steels utilized in the production of valves in car engines, on the protective properties of the oxide scale and its adherence to the surface of the oxidized materials has been studied under isothermal and thermal cycle conditions. Oxidation measurements have been carried out at 1173 K. It has been found that yttrium addition improves considerably the scale adherence to the substrate surface, increasing thereby corrosion resistance of the studied materials.
Sparta und die Genese des politischen Freiheitsbegriffs
Authors: Bernhardt Rainer
Published: May 2014

Ein politisches Freiheitsbewusstsein, das im Gegensatz zur Tyrannis stand, war wahrscheinlich schon bei Solon vorhanden. Der entscheidende Anstoß für die Verwendung des Begriffs ἐλευθερία/eleutheria gingjedoch von Sparta aus, wo sich die elitären Vollbürger,ähnlich wie die Vollbürger in Gortyn, als ἐλεύθεροι/eleutheroibetrachteten. Diese ἐλευθερία/eleutheria implizierte u.a. auch die Freiheit von Tyrannis. Aus diesem Selbstverständnis heraus wandelte Pausanias 479 v. Chr. in Plataiai den Kult des Ζεὺς Σωτήρ/Zeus Soterin den des Ζεὺς Ἐλευθέριος/Zeus Eleutheriosum, wobei sich der Schwerpunkt dieser ἐλευθερία/eleutherianach Lage der Dinge zwangsläufig auf die äußere Freiheit verlagerte, und stellte Plataiai unter den Schutz aller griechischen Bundesgenossen. Mit der Erweiterung von ἐλευθερία/eleutheriavon der inneren auf die äußere Unabhängigkeit entstand der umfassende politische Freiheitsbegriff, der für Sparta zwar anfangs noch keine große Bedeutung hatte, den aber nach und nach – durchaus zögernd ‒ alle Griechen übernahmen. Während in Griechenland Freiheit zunächst als Unabhängigkeit vom Perserreich verstanden wurde, verschob sich auf Sizilien nach der Abwehr der Karthager und Etrusker der Akzent auf die Befreiung von der Tyrannis. Zur vollen Entfaltung gelangte der politische Freiheitsbegriff nicht in den Kriegen Athens gegen das Perserreich seit 478, sondern erst um die Mitte des 5. Jahrhunderts, als die Theten in Athen die politische Gleichberechtigung erlangt hatten, und ging wenig später eine Symbiose mit dem Begriff δημοκρατία/demokratia ein. Die politische ἐλευθερία/eleutheriawurde zu einem Teil der griechischen Identität. Gegen Ende des 5. Jahrhunderts entstand daraus auch der griechische Herrschaftsanspruch gegenüber den „Barbaren“.
Treatment of refractory substance-induced psychosis in adolescent males with a genetic predisposition to mental illness
Authors: Rahmani Mariam , Paul Sean , Nguyen Mathew L.
Published: May 2014

This article presents two cases of adolescent males who were admitted to our inpatient psychiatric unit with a psychotic, disorganized presentation. Both males had a genetic vulnerability to mental illness and reported significant substance use. Their symptoms were refractory to treatment and required the use of clozapine. Both patients experienced significant side effects, which limited the maximum daily dose of clozapine. However, they responded to a dose that was much lower than that typically used in adults. There is significant evidence in the literature about cannabis use triggering psychotic breaks in vulnerable individuals. We speculate that substance use (including synthetic cannabinoids) triggers treatment-resistant psychosis that requires the use of clozapine. Further, lower doses of clozapine may be sufficient to treat the substance-induced psychotic symptoms than those typically used in adult schizophrenia.

Authors: Papanikolaou M. , Skenteris N. , Piperakis S.M.
Published: May 2014

The present study investigated the effect of low, medium, and high traffic road noise as well as irrelevant background speech noise on primary school children’s reading and mathematical performance. A total of 676 participants (324 boys, 47.9% and 352 girls, 52.1%) of the 4th and 5th elementary classes participated in the project. The participants were enrolled in public primary schools from urban areas and had ages ranging from 9 to 10 years and from. Schools were selected on the basis of increasing levels of exposure to road traffic noise and then classified into three categories (Low noise: 55–66 dB, Medium noise: 67–77 dB, and High noise: 72–80 dB). We measured reading comprehension and mathematical skills in accordance with the national guidelines for elementary education, using a test designed specifically for the purpose of this study. On the one hand, children in low-level noise schools showed statistically significant differences from children in medium- and high-level noise schools in reading performance (p<0.001). On the other hand, children in low-level noise schools differed significantly from children in high-level noise schools but only in mathematics performance (p=0.001). Girls in general did better in reading score than boys, especially in schools with medium- and high-level noise. Finally the levels of noise and gender were found to be two independent factors.
Modified DSTATCOM Topology with Reduced DC Link Voltage for Reactive and Harmonic Power Compensation of Unbalanced Nonlinear Load in Distribution System
Authors: Geddada Nagesh , Karanki Srinivas B. , Mishra Mahesh K.
Published: May 2014

This paper proposes a modified four-leg distribution static compensator (DSTATCOM) topology for compensation of unbalanced and nonlinear loads in three-phase four-wire distribution system. DSTATCOM, connected in parallel to the load, supplies reactive and harmonic powers demanded by unbalanced nonlinear loads. In this proposed topology, the voltage source inverter (VSI) of DSTATCOM is connected to point of common coupling (point of interconnection of source, load, DSTATCOM) through interface inductor and series capacitance, unlike the conventional topology which consists of interface inductor alone. Load compensation with a lower value of input DC link voltage of VSI is possible in this modified topology compared to conventional topology. A comparative study on modified and conventional topologies in terms of voltage rating of inverter power switches, switching losses in VSI and power rating of input DC capacitor of VSI is presented. The detailed design aspects of DC link capacitor and interface series capacitor are also presented. The reference filter currents are generated using instantaneous symmetrical component theory and are tracked using hysteresis current control technique. A detailed simulation study is carried out, to compare the compensation performances of conventional, modified topologies using PSCAD simulator and experimental studies are done to validate the simulation results.

Published: May 2014

Some physical properties of the naked oat seeds were determined as a function of moisture content ranging from 9.56 to 18.07% (wet basis, w.b.). Seed length, width, thickness, and geometric mean diameter were increased from 7.89 to 8.81 mm, 2.32 to 3.09 mm, 1.85 to 2.77 mm, and 3.24 to 4.22 mm, respectively, with the increase of moisture content. The bulk and true densities of the seed samples were decreased from 682.1 to 533.1 kg/m3 and from 1,280.6 to 1,162.8 kg/m3, respectively. The average static friction coefficients of the seeds on the surfaces of plywood, stainless steel, and polypropylene knitted bags were increased from 0.403 to 0.674, from 0.371 to 0.496, and from 0.562 to 0.765, respectively, when the moisture content of these samples were increased from 9.56 to 18.07% (w.b.). The static angle of repose varied from 24.38° to 39.17° in the moisture content range.
