Effect of Gypsum Board Orientation on Board Fall-Off in Fire Resistance Test Assemblies
Authors: Sultan Mohamed A.
Published: December 2015

This paper presents and discusses the results of an attempt that was made to determine the Type X, 12.7 mm and 15.9-mm-thick, gypsum board fall-off in fire resistance tests of different orientations (horizontal and vertical assemblies) for 83 and 41 full-scale floor and wall test assemblies, respectively. These tests were conducted at the National Research Council of Canada in accordance with the CAN/ULC–S101 standard, which is similar in fire exposure to the ASTM E119 fire resistance standard for updating the fire resistance ratings in the listed wall and floor assemblies in Part 9, Appendix A, of the National Building Codes of Canada. The results of tests were further analyzed to investigate the gypsum board fall-off for wall and floor assemblies. Four different approaches were investigated using the floor assemblies' test results to identify board fall-off criterion. The proposed temperature criterion selected is based on the sudden temperature rise on the back side of the fire exposed gypsum board due to the board fall-off. The same criterion was also used in predicting the gypsum board fall-off in wall assemblies. A comparison of the gypsum board fall-off based on test observations and temperature measurements and temperature criteria for gypsum board fall-off for both vertical and horizontal applications are presented and discussed.
Disruption of Epithalamic Left–Right Asymmetry Increases Anxiety in Zebrafish
Authors: Facchin Lucilla , Duboué Erik R. , Halpern Marnie E.
Published: December 2015

Differences between the left and right sides of the brain are found throughout the animal kingdom, but the consequences of altered neural asymmetry are not well understood. In the zebrafish epithalamus, the parapineal is located on the left side of the brain where it influences development of the adjacent dorsal habenular (dHb) nucleus, causing the left and right dHb to differ in their organization, gene expression, and connectivity. Left–right (L-R) reversal of parapineal position and dHb asymmetry occurs spontaneously in a small percentage of the population, whereas the dHb develop symmetrically following experimental ablation of the parapineal. The habenular region was previously implicated in modulating fear in both mice and zebrafish, but the relevance of its L-R asymmetry is unclear. We now demonstrate that disrupting directionality of the zebrafish epithalamus causes reduced exploratory behavior and increased cortisol levels, indicative of enhanced anxiety. Accordingly, exposure to buspirone, an anxiolytic agent, significantly suppresses atypical behavior. Axonal projections from the parapineal to the dHb are more variable when it is located on the right side of the brain, revealing that L-R reversals do not necessarily represent a neuroanatomical mirror image. The results highlight the importance of directional asymmetry of the epithalamus in the regulation of stress responses in zebrafish.

SIGNIFICANCE STATEMENTThe asymmetric epithalamus of zebrafish has emerged as a valuable model to explore the formation and function of left–right differences in the brain. To probe the relationship between brain laterality and behavior, we examined the effects of left–right reversal of epithalamic asymmetry or symmetric development on behavior. In both cases, zebrafish showed increased measures of fear/anxiety, including reduced exploratory behavior and delayed exit from a confined space. Adults with reversed L-R asymmetry also have elevated cortisol levels relative to controls. The results reveal the importance of directional asymmetry of the dorsal diencephalon in the modulation of anxiety.

Black and Brown Tumbling the Walls Together: African Americans and Mexican Americans Accessing Higher Education through Intersectoral Points of Contact and Interactions
Authors: Vásquez Irene E.
Published: December 2015

While studies of relations between African American and Mexican American communities often highlight conflict or collaboration as organizing principles, this article seeks to identify where organizing efforts and advocacy intersected between these constituencies but also where influences and ideologies conjoined their social critiques. While this article focuses on how African American activists and advocacies informed Mexican American struggles, the point is to demonstrate that these groups did not operate in isolation or in organizational vacuums. This article provides an analysis of the interstitial moments of interethnic solidarities between African American and Chicana/o student and community activists in their efforts to establish cultural centers and ethnic studies programs at UCLA in 1968. Highlighting the intersectional struggles by Chicana/o and African American students, this exploratory work examines primary and secondary sources including newspaper articles, group statements and proposals, and institutional reports. Collaborative moments in the history of Chicana/o and African American student activism occurred that reflected previous Black and Brown solidarity relations as well as newly developing interactions among students. Contextually, my research situates activism on behalf of Chicana/o studies within the Civil Rights period. First, I examine the Civil Rights contexts within which Chicana/o and African American collaborative relations developed and the influences they brought to bear on activists and their agendas. Second, I note some networks and associations that occurred between African American and Chicana/o activists seeking self-determination and empowerment. Third, I feature some joint activities at UCLA that resulted in concrete institutional outcomes. In conclusion, I argue that the 1968 struggles to reform higher education became a pivotal site for Black and Brown solidarity.

Student-Led Black Material Culture—1968: A Curator’s Thoughts
Authors: Ruffins Fath Davis
Published: December 2015

Although not all sociopolitical eras are characterized by a particular form of dress, the young people of the late 1960s actively produced distinctive clothing, jewelry, and hair styles that would allow any knowledgeable historian of the future to instantly date a photograph to the late 1960s, in this case 1968–1969. What makes this “look” so characteristic of its time? What kinds of visual or artifactual sources would help a curator in placing this photograph and the people and objects it documents in a cultural/stylistic era? These sources help answer further questions: what were ordinary students and faculty members wearing before this era (circa 1968) and after? What makes the clothing, postures, and hairstyles (which are collectively called “costume” or “dress”) worthy of documenting and preserving? How does understanding these clothing styles contribute to an intellectual comprehension of this moment in the American past?
Challenging the Terms of Order: Representations of the Detroit Rebellions, 1967–1968
Authors: Camp Jordan T.
Published: December 2015

While many analysts have commented on the representation of 1968 campus events and antiwar demonstrations, less attention has been paid to the global significance of the dramatic struggles in industrial Detroit during the period. The meanings of events in the city were intensely fought over. As Stuart Hall, Chas Critcher, Tony Jefferson, John Clarke, and Brian Roberts observed, the events of 1968 were “an act of collective will, the breaks and ruptures stemming from the rapid expansion in the ideology, culture and civil structures of the new capitalism . . . in the form of a ‘crisis of authority.’” In Detroit the crisis of authority was expressed in the form of popular political struggles against racism, state violence, and the contradictions of life in the industrial capitalist city. This article asks and answers the following research questions about the struggle over the meaning of this decisive turning point in US history: What was the relationship between racial ordering, uneven capitalist development, and mass antiracist and class struggles? How did Black working-class organic intellectuals resist and alter hegemonic definitions of the situation? How are the dialectics of insurgency and counterinsurgency to be best theorized during this precise historical conjuncture?
“There Was No Spartacus Here”: Norma Montoya and Art as Abeyance in the Estrada Courts Mural Program
Authors: Gomez Jonathan D.
Published: December 2015

The social processes that link collective art making to social movement activism enable community-based art making to serve as a key mechanism for art-based community making. Chicana/o mural art has been an important register of ordinary people’s self-active creativity, of their determination to create new democratic social spaces and new social identities capable of effecting social change based on egalitarian principles. When they are not painting on walls, mural artists hold various jobs and fulfill diverse roles as teachers, community organizers, and unofficial archivists. They do their work in solidarity with all aggrieved groups, especially young people who confront unfavorable material conditions in their neighborhoods. The collective mural-making practices of artists in the Chicana/o mural movement throughout the US Southwest during the 1970s offer an important focal point for understanding the practice and promise of intergenerational transfers of knowledge, collective art making, and self-active creativity not directly controlled by powerful institutions and social groups.
Remembering Dr. Angelou, 1928–2014
Authors: Glass Kathy
Published: December 2015

Dr. Angelou was a teacher to millions who savored her lectures, prose, and poetry. As we continue to mourn her passing, may we apply her wisdom to our nation’s ongoing freedom struggles. The non-indictment in the Michael Brown case, the non-indictment in the Eric Garner case, and the killing of twelve-year-old Tamir Rice, who was shot while holding a toy gun, all raise questions about the ways Black bodies get policed and have led many to publicly affirm that “Black lives matter.” The national protests and movements these incidents sparked have drawn large multiethnic and multigenerational crowds demonstrating a coalitional consciousness such as Dr. Angelou would champion. In this collective spirit we must continue to tackle structural racism in the criminal justice system, and confront longstanding disparities in health, housing, lending, and wealth.
Non-Invasive Assessment of Inflammation and Treatment Response in Patients with Crohn’s Disease and Ulcerative Colitis using Contrast-Enhanced Ultrasonography Quantification

Published: December 2015

ackground & Aim: Novel biological therapies in Crohn’s disease (CD) or Ulcerative colitis (UC) require a proper follow-up for the assessment of bowel inflammation. While endoscopy is the standard method, the imaging techniques using contrast, particularly contrast enhanced ultrasonography (CEUS), are better tolerated by the patients and can be used more frequently. Our aim was to find the usefulness of dynamic CEUS quantification as compared to endoscopy in the assessment of disease activity and in the follow-up under therapy of the patients suffering from either CD or UC.

Method: We have prospectively evaluated 67 patients with UC and 46 with CD, diagnosed by ileo-colonoscopy and biopsy, comparing the endoscopic scores with clinical scores, C reactive protein (CRP), intestinal wall thickness, layer scores after CEUS and TIC parameters (using SonoLiver® software – Imax, RT, TTP, mTT and AUC). For 25 patients with UC and 13 with CD we performed comparisons of the parameters before and after 3 months of treatment and correlated them with the changes in the endoscopic scores.

Results: For UC, time-intensity curves (TIC) volume parameters (AUC) correlated better with endoscopy (ρ=0.64) than the clinical score (ρ =0.62). Other parameters such as CRP and thickness showed significant but less strong correlation, while TIC flow parameters (RT, TTP and mTT) did not show a significant correlation. Results were similar for CD (ρ=0.64 for Imax vs ρ=0.58 for CDAI). The best predictor for endoscopic improvement in both UC and CD was ln(AUC), with a Wilcoxon Z score of 3.76 and 2.61, respectively. There was also a good correlation between the difference of its values and the difference in endoscopic scores before and after the treatment (rho is 0.68 in UC and 0.73 in CD).

How Far we are towards Eradication of HBV Infection
Authors: Voiculescu Mihai
Published: December 2015

Hepatitis B virus (HBV) infection is a major health problem with an important biological and a significant socio-economic impact all over the world. There is a high pressure to come up with a new and more efficient strategy against HBV infection, especially after the recent success of HCV treatment. Preventing HBV infection through vaccine is currently the most efficient way to decrease HBV-related cirrhosis and liver cancer incidence, as well as the best way to suppress the HBV reservoir. The vaccine is safe and efficient in 80-95% of cases. One of its most important roles is to reduce materno-fetal transmission, by giving the first dose of vaccine in the first 24 hours after birth. Transmission of HBV infection early in life is still frequent, especially in countries with high endemicity.Successful HBV clearance by the host is immune-mediated, with a complex combined innate and adaptive cellular and humoral immune response. Different factors, such as the quantity and the sequence of HBV epitope during processing by dendritic cells and presenting by different HLA molecules or the polymorphism of T cell receptors (TOL) are part of a complex network which influences the final response. A new potential therapeutic strategy is to restore T-cell antiviral function and to improve innate and adaptive immune response by immunotherapeutic manipulation.It appears that HBV eradication is far from being completed in the next decades, and a new strategy against HBV infection must be considered.

Controlled synthesis of few layer graphene films for gas sensor applications
Authors: Chaudhari S. , Graves A.R. , Cain M.V. , Stinespring C.D.
Published: December 2015

A novel approach for synthesis of few layer graphene films on SiC has been developed which uses halogen based inductively coupled-reactive ion etching (ICP-RIE) and rapid thermal annealing (RTA) in atmospheric pressure argon. These films have been characterized using x-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. Surface characterization by XPS reveals the presence of defects similar to those observed for graphene oxide (GO) but at a much lower levels that those observed for GO. As in the case for GO, the defect density could be further reduced by chemical methods which improved carbon to defect ratio based on XPS analyses. Raman spectroscopy showed the presence of D, G and 2D peaks at 1330 cm-1, 1599 cm-1and 2671 cm-1, respectively, which is comparable with similar graphene films formed by thermal annealing of SiC. The full widths at half max (FWHM) for these peaks was, however, comparable to those observed for GO. Electrical characterization of these graphene films using collinear four point probe measurements showed the electrical resistivity of these films is consistent with the observed values for few layer exfoliated graphene. Gas sensor structures were fabricated using lithography free methods, and initial gas response studies were performed for H2.
High-pressure Metal Hydride Tank for Fuel Cell Vehicles

Published: December 2015

A new type of hydrogen-absorbing alloy tank has been developed. The high-pressure metal hydride (MH) tank has been designed based on a 35 MPa cylinder vessel. The heat exchanger module is integrated into the tank. Its advantage over high-pressure cylinder vessels is its large hydrogen storage capacity, for example 7.3 kg with a tank volume of 180 L. Cruising range is about 2.5 times longer than that of a 35 MPa cylinder vessel system with the same volume.

The hydrogen-charging rate of this system is equal to the 35 MPa cylinders without any external cooling facility. Furthermore, release of hydrogen at 243 K is enabled due to the use of a hydrogen-absorbing alloy with a high disassociation pressure, Ti-Cr-Mn alloy with AB2 laves phase. It is thought that the high-pressure MH system is one realistic option for fuel cell vehicles to achieve a cruising range of over 700 km.
Tuning of Hidden Order and Superconductivity in URu2Si2 by Applied Pressure and Re Substitution
Authors: Butch Nicholas P. , Jeffries Jason R. , Yukich Benjamin T. , Maple M. Brian
Published: December 2015

Single crystals of URu2-xRexSi2 have been grown via the Czochralski technique. Detailed electrical transport studies under pressure on single crystals of URu2Si2 confirm that the zero-temperature critical field is suppressed smoothly towards an extrapolated critical pressure of 15 kbar, which also corresponds to the accepted critical pressure of the hidden order phase. Improving on previous work on polycrystalline samples, studies of single crystals of URu2-xRexSi2 have provided more precise tracking of the suppression of both the hidden order phase at low doping and the ferromagnetic phase at intermediate Re concentrations.
Talk in feminised occupations
Authors: Mcdowell Joanne
Published: December 2015

It is widely accepted amongst scholars that gender is socially constructed. Gender identity is not something one has but does, and language is one resource that is crucial when constructing, maintaining and performing one’s identity. Recent sociolinguistic research has illustrated that a speaker’s linguistic behaviour can be shaped by their surrounding context, and one such ever-growing area of study is that of workplace discourse, especially within jobs which could be classified as gendered. Scholars have focused mainly on women’s linguistic behaviour in non-traditional employment (i.e. police, engineers, Information Technology). To date, there has been relatively little research into the linguistic behaviour of men working in occupations seen as ‘women’s’ work (i.e. nursing, primary school teaching). To address this gap, this article focuses on men’s discursive behaviour in the occupation of nursing to investigate whether they utilise language to perform a masculine identity in line with hegemonic characteristics, or whether they use the language indexical of the feminised environment in which they work. Empirical data, collected by three male nurse participants specifically within nurse-nurse interactions whilst at work in a Northern Ireland hospital, is explored using discourse analysis and the Community of Practice paradigm. Results indicate that the male nurses’ discursive behaviour does not differ from that which sociolinguistic literature has repeatedly classed as ‘feminine’. It is then argued that the nurses’ language fulfils discourse tasks essential to the work role. In short, the men are doing being a nurse.
De l'Utopie radicale à la bonne gouvernance: le cas du Québec
Authors: Côté Denyse , Simard Étienne
Published: December 2015

Le Québec, on le sait, a connu dans la deuxième moitié du XXe siècle un mouvement social et politique qui a radicalement transformé son échiquier politique, économique et social, de même que sa culture. Cette communication a pour but de présenter la difficulté d’émergence de nouvelles utopies dans le cadre du système qui en a résulté. La génération radicale des années 1960 et 1970 aura en effet laissé derrière elle des structures, une culture politique et un discours qui occupent l’espace social et laissent peu de place à l’innovation. Comment les nouvelles générations de militants radicaux y font-ils leur place? Comment se situent-ils face aux politiques et discours socio-démocrates issus de ce demi-siècle d’histoire québécoise et au virage néolibéral déjà bien entamé? Quels espaces peuvent-ils investir? Quels blocages rencontrent-ils? Voilà les questions auxquels cette communication tentera de répondre. Cette analyse sera ancrée dans un contexte régional et d’une analyse critique de l’approche néolibérale de la décentralisation du gouvernement et de la lente corporatisation de la société québécoise.
The Quest for Caribbean Identities: Postcolonial Conflicts and Cross-Cultural Fertilization in Derek Walcott’s Poetry
Authors: Douillet Catherine M
Published: December 2015

ABSTRACT: This paper investigates how the political merges with the literary in Derek Walcott’s poetry, using the poems “A Latin Primer” and “The Light of the World” as primary examples. In these two poems, Walcott explores the colonial wounds of the Caribbean region and the various consequences of colonialism for the forging of Caribbean’s contemporary identities. He proposes a model of Caribbeanness that values racial multiplicity and cross-dialogues between cultures, including, perhaps problematically, the European cultural tradition, as fertilizing. For Walcott, poetic creativity serves to truly unify and find points of connections in a disjointed postcolonial world. This paper examines the implications of Walcott’s stances on postcolonial identity politics and compares Walcott to several French Caribbean authors. RÉSUMÉ: Cet article explore comment la polique et la littérature fusionnent dans la poésie du Prix Nobel de Littérature Derek Walcott, utilisant les poèmes “A Latin Primer” et “The Light of the World” comme exemples principaux. Dans ces deux poèmes, Walcott analyse les blessures coloniales encourues par les Antilles et les différentes conséquences du colonialisme pour la création des identités antillaises contemporaines. Il propose un modèle d’antillanité qui célèbre la multiplicité raciale et les dialogues fertilisateurs entre les cultures, y compris la culture européenne, donnant peut-être ainsi matière à controverse. Pour Walcott, la créativité poétique sert à unifier et connecter un monde postcolonial disjoint. Cet article examine les différentes implications des positions de Walcott concernant les politiques d’identités postcoloniales et compare Walcott à certains auteurs des Antilles francophones.

Published: December 2015

OBJETIVO: Analisar a relação entre a qualidade da dieta e o número e os locais de refeições de escolares de 7 a 10 anos do município de São Paulo. MÉTODOS: Trata-se de um estudo transversal, feito em 2013, com escolares de 7 a 10 anos de idade de duas escolas municipais de São Paulo. O consumo alimentar foi coletado a partir de três recordatórios de 24 horas, tendo sido calculado o Índice de Qualidade da Dieta Revisado. As médias de cada componente do índice foram analisadas segundo hábito de tomar café da manhã, número de refeições diárias, em casa, na escola e fora do lar. RESULTADOS: A maioria dos escolares ingeriu café da manhã, realizou menos de cinco refeições, nenhuma refeição na escola, três ou mais refeições em casa e nenhum consumo de refeições fora do lar. O hábito de tomar café da manhã apresentou associação com o maior consumo de vegetais e de leite e o maior número de refeições diárias com o menor consumo de sódio. O maior consumo de refeições em casa esteve associado ao menor consumo de gordura saturada, calorias de gordura sólida e açúcar e a melhor qualidade da dieta. As refeições fora do lar apresentaram associação com o maior consumo de cereais integrais e de calorias de gordura sólida e açúcar. CONCLUSÃO: O maior consumo de alimentos saudáveis ocorre em casa, portanto ações de educação alimentar e nutricional devem incentivar o consumo de alimentos no lar e as escolhas alimentares saudáveis fora do lar.

OBJETIVO: Avaliar a qualidade da dieta entre consumidores e não consumidores de carnes vermelhas e processadas em residentes do município de São Paulo. MÉTODOS: Foram utilizados dados do estudo transversal do Inquérito de Saúde de São Paulo - 2008, com informações de 726 indivíduos que possuíam todas as informações dos inquéritos dietéticos, sendo 195 adolescentes, 272 adultos e 259 idosos. Os dados de consumo alimentar foram obtidos por dois recordatórios alimentares de 24 horas, aplicados em dias não consecutivos, incluindo final de semana e todas as estações do ano, e um questionário de frequência alimentar para estimar a frequência do consumo de carnes vermelhas e processadas. A ingestão alimentar habitual foi estimada pelo Multiple Source Method. O Índice de Qualidade da Dieta - Revisado foi calculado a partir da ingestão habitual dos participantes. As recomendações da Organização Mundial de Saúde foram utilizadas para estimar a participação percentual dos macronutrientes no valor energético total. RESULTADOS: O grupo de não consumidores apresentou maior pontuação média do índice (p=0,006), do grupo das frutas integrais (p=0,022), dos leites e derivados (p<0,001) e menor pontuação média de gordura sólida, álcool e açúcar de adição (p=0,039) e carnes, ovos e leguminosas (p<0,001). Também se mostrou maior percentual de adequação de gordura no grupo de não consumidores de carnes vermelhas e processadas. CONCLUSÃO: Sugere-se que não consumidores de carne vermelha e processada tenha melhor qualidade da dieta e maior adequação da contribuição energética dos lipídeos em comparação com consumidores desse alimento.
A entrevista social no processo de avaliação geriátrica ampla
Authors: Sanchez Maria Angélica dos Santos , Mota Gabriela Maia da Silva
Published: December 2015

Resumo As novas diretrizes do pacto de gestão fortalecem as ações de atenção à saúde do idoso a partir do momento em que se torna uma das prioridades do Ministério da Saúde. Além disso, a Política Nacional de Saúde da Pessoa Idosa preconiza uma atenção integral e integrada com ênfase em abordagens multidimensionais que buscam resgatar ou preservar a autonomia e independência do sujeito que envelhece. Um novo paradigma na atenção emerge trazendo a avaliação geriátrica ampla, realizada por uma equipe multidisciplinar, como uma prática essencial no rastreamento e identificação dos variados problemas que acometem o indivíduo idoso. Nesta modalidade de avaliação é fundamental um olhar direcionado aos problemas sociais que podem influenciar no restabelecimento da saúde ou no aparecimento de novas doenças. A entrevista social é um instrumento técnico que fornecerá ao profissional subsídios para realizar uma avaliação que possa gerar uma intervenção adequada a partir do conhecimento das possibilidades e limitações dos usuários que buscam atenção em unidades geriátricas. O objetivo deste trabalho é tecer algumas considerações acerca da avaliação social no processo de avaliação geriátrica ampla. É também um esforço preliminar de contribuir com o fazer profissional do assistente social, visto que as produções teóricas neste campo são escassas e as questões sociais se constituem em elementos essenciais para o estabelecimento de condutas terapêuticas eficazes.

Published: December 2015

Resumo O presente estudo teve por objetivo avaliar os efeitos do treinamento de força sobre os níveis basais de IGF1 e de força muscular nas fases neurogência e miogênica de idosas sedentárias. A amostra foi constituída de 24 idosas voluntárias, subdivididas, randomicamente, em dois grupos: grupo experimental (GE, n = 13; 65,62±5,36 anos) e grupo controle (GC, n = 11; 71,45±5,72 anos). Foi utilizado o protocolo de uma repetição máxima (BAECHLE & GROVES, 1992) para avaliação da força muscular máxima e de Quimiluminescência - IMMULITE - DPC MED LAB, para o IGF1. Foram utilizados o teste de Kruskal-Wallis (GE, em relação aos três momentos) seguido das comparações múltiplas de Dunn; o teste de Wilcoxon (GC, em relação aos dois momentos) e o teste de Mann-Whitney (comparação inter-grupos). Os resultados revelaram aumento significativo (p<0,05) no IGF1 (GCpós x GEsemana20 - ∆=54,29 ng/ml, p=0,009) e em todas as variáveis da força muscular (GEsemana4 x GEsemana20, ∆%=39,23% e GEpré-teste x GEsemana20, ∆%=56,08%; p<0,05). Desta forma, pode-se concluir que o treinamento de força muscular inferiu em aumento significativo desta variável e dos níveis séricos de IGF1 apenas na fase miogência.

Consideramos os resultados de duas pesquisas em que investigamos as ações de grupos de estudantes ao longo de atividades investigativas, buscando verificar as relações entre as práticas epistêmicas por eles desenvolvidas e as estratégias articuladas pela professora na condução das atividades. A análise contou com categorias presentes na literatura da área e outras elaboradas ao longo das pesquisas. O conceito de práticas epistêmicas, segundo uma perspectiva sociocultural de educação, ressalta o papel de uma comunidade de prática qualquer na decisão sobre o que pode ser considerado conhecimento relevante e as formas adequadas de construí-lo. Nessa perspectiva, as atividades investigativas desenvolvidas pelos grupos de alunos analisados geraram espaço para uma variedade de práticas epistêmicas, distribuídas nas instâncias sociais de produção, comunicação e avaliação do conhecimento.
Entre França e Brasil: viagens antropológicas num campo (religioso) minado
Authors: Birman Patrícia
Published: December 2015

Resumo Partindo da premissa de que o par sociológico clássico “religião/seita” não possui a mesma densidade histórica ou o mesmo valor descritivo em todos os contextos, a autora investiga as atividades de uma associação francesa empenhada no combate às “seitas”, tomando como foco de análise as acusações contra um determinado templo umbandista em Paris. As acusações, visando tanto as pretensões terapêuticas quanto as pretensões religiosas do templo, seriam calcadas numa percepção que busca traduzir experiências diversificadas em princípios únicos e de valor universal. Na sua defesa, os representantes do templo destacam sua tentativa sistemática e institucionalizada de incorporar os diferentes universos “étnicos” da sua população como meios adequados para conviver com as diferenças culturais numa mesma nação. A comparação dos dois discursos mostra como o projeto multiculturalista americano contrasta fortemente com o projeto francês de homogeneização das diferenças.
Traficando con hombres: la antropología de la masculinidad
Authors: Gutmann Matthew C.
Published: December 2015

Resumen La antropología siempre ha tenido que ver con hombres hablando con hombres sobre hombres, no obstante es bastante reciente el que dentro de la disciplina unos pocos hayan realmente examinado a los hombres como hombres. Este articulo explora el cómo entienden, utilizan y discuten los antropólogos la categoría de masculinidad mediante la revisión de análisis recientes sobre los hombres como sujetos que tienen género a la vez que lo otorgan. Se comienza con las descripciones de cuatro formas distintas de definición y tratamiento de la masculinidad en la antropología, y se presta atención especial a las relaciones de diferencia, desigualdad, y mujeres con el estudio antropológico de las masculinidades, incluida la curiosa omisión de la teoría feminista por patie de numerosos antropólogos estudiosos de lo varonil. Los temas específicos que se discuten abarcan las diversas economías culturales de la masculinidad, la noción de regiones culturales en relación a las imágenes de hombría, amistad masculina, machismo, corporalidad masculina, violencia, poder, y fisuras sexuales.
Atmospheric Effects on RTK Network in Florida
Authors: Berber M. , Arslan N.
Published: December 2015

Commonly used real time kinematic (RTK) network (RTK Network) techniques, i.e., MAX, I-MAX, FKP and VRS, are tested by taking monthly measurements for a year in Florida. Additionally, RTCM message versions 2 and 3 are used with I-MAX and VRS measurements. The results revealed that mostly, horizontal coordinates vary a few centimeters and generally changes in vertical coordinates are less than two decimeters. In terms of horizontal coordinates, the best results are produced by I-MAX3 method and FKP yielded the worst results. In terms of vertical coordinates, almost all results look alike; however, the best results are produced by VRS3 method. It appears that I-MAX3 performed better than I-MAX2 and VRS3 performed better than VRS2. Yet, MAX did not stand out among other techniques.

Este trabalho apresenta metodologia para mapeamento da vulnerabilidade costeira à elevação do Nível Médio do Mar (NMM) em escala local, com estudo de caso na orla marítima da Ilha de Madre de Deus/BA. Essa orla marítima é densamente ocupada por bairros residenciais e instalações da indústria petrolífera. Para isso, foi criado um índice de vulnerabilidade costeira com a combinação de quatro variáveis geológicas (geomorfologia, declividade, elevação e taxa de erosão/acreção na face de praia), determinadas em levantamentos sazonais (verão e inverno) de perfis de praia georreferenciados e niveladas em relação ao NMM, e três variáveis de processos físicos costeiros (taxa de elevação do nível médio do mar, altura significativa de onda e amplitude de maré média). O mapa representou a variação da vulnerabilidade relativa ao longo de distintos setores da linha de costa possibilitando identificar a combinação mais crítica das variáveis, ou seja, áreas prioritárias às intervenções antrópicas para redução das vulnerabilidades por meio de estratégias de prevenção, mitigação e/ou adaptação socioeconômicas e ambientais aos impactos da elevação do NMM. Os resultados mostraram alto potencial na aplicação da metodologia em setores de beira-mar, cuja pequena extensão requer o mapeamento em escala de detalhe.
MINERAÇÃO DE DADOS APLICADA À DISCRIMINAÇÃO DA COBERTURA DA TERRA EM IMAGEM LANDSAT 8 OLI

Published: December 2015

O presente trabalho tem como objetivo investigar os descritores espectrais, extraídos das bandas do Landsat 8, e topográficos, provenientes de dados do TOPODATA, que auxiliam na discriminação das classes de cobertura da terra através de uma árvore de decisão gerada por mineração de dados. Foram extraídas medidas estatísticas de amostras referentes a 12 classes, coletadas no município do Rio de Janeiro, de um banco de dados composto por 18 planos de informação. Os resultados apontaram que entre os descritores estatísticos, prevaleceram a média e mediana. Como descritor espectral, merece destaque a banda 1 (ultra-azul), selecionada para discriminar, além das classes de água, as classes de vegetação e não-vegetação. O minerador utilizou o Índice de Vegetação por Razão Simples (RS) em todas as árvores a despeito do Índice de Vegetação por Diferença Normalizada (IVDN). A declividade também foi inserida nas três árvores para separar o afloramento rochoso da vegetação de baixo porte. Em relação aos níveis digitais, não foi utilizado nenhum descritor de radiância nas quatro árvores. Considerando o grande volume de dados produzidos e armazenados atualmente, pode-se afirmar que a mineração é um importante recurso para a extração de informações de volumosos bancos de dados em curto espaço de tempo.
AVALIAÇÃO AUTOMÁTICA DA ACURÁCIA RELATIVA DE DADOS LIDAR AEROTRANSPORTADO
Authors: Dresch Gabriel , Santos Daniel Rodrigues dos
Published: December 2015

Neste trabalho é proposto um método automático para o controle da acurácia relativa de dados LiDAR (Light Detection and Ranging) aerotransportados usando superfícies planas, linhas retas e pontos. Primeiramente, é realizada uma filtragem dos dados LiDAR, através do filtro morfológico progressivo e o filtro RANSAC (Random Sample Consensus). Em seguida, as superfícies planas são extraídas automaticamente sobre os telhados encontrados nas faixas adjacentes através do algoritmos crescimento de região. Posteriormente, as correspondências entre as feições extraídas em cada faixa são estabelecidas e os parâmetros de transformação são estimados através de uma variante do método ICP. Finalmente, para avaliar simultaneamente a acurácia plani-altimétrica dos dados LiDAR são empregadas linhas retas extraídas a partir da interseção de planos adjacentes. Para avaliar o método proposto foi conduzido um experimento com dados LiDAR obtidos numa região urbanizada recoberta por 2 faixas com densidade de 1 ponto/m². A avaliação da acurácia relativa desses dados é realizada automaticamente e os resultados obtidos com o método proposto mostraram que a média das distâncias ponto-a-plano é de -0,0019 cm e a raiz quadrada do erro médio quadrático é de 6,04 cm.

Abstract The aim of this study was to identify and determine the prevalence of Eimeria species affecting sheep raised extensively in a semiarid region of Brazil. Fecal samples of native sheep were collected during the rainy and dry seasons. The degree of infection was determined by counting oocysts per gram (OPG) of feces, and the morphometric method was used for species identification. Oocysts were found in all the properties assessed, in which 68.3% of the animals were infected. The prevalence of oocysts was influenced by the season and animal category (P<0.05). It was higher during the rainy season than the dry season (80.2% vs. 55.8%) and highest in young animals than the adults animals (68.2% vs. 39.6%). The OPG was lower during the dry season (1,269 ± 312 vs. 4,400 ± 1,122). Ten species were found; of these, E. ovinoidalis, E. granulosa, E. faurei, and E. crandallis were the most frequent. E. ovinoidalis and E. crandallis were found in all properties, with their prevalences being 19.4% and 13.6% respectively. The high prevalence of pathogenic species shows that eimeriosis is a risk for animals raised extensively in the semiarid region.

Published: November 2015

Background: Over the last decade have seen a drastically increase of interest in the Single photon avalanche diode (SPAD) detectors applications at many variety of quantum experiments where the detection efficiency at single-photon level is required. The calibration of such detectors involves predominantly the determination of the detection efficiency.

Methods: The present study was carried out at Department of Photometry and Applied Radiometry, Physikalisch-Technische Bundesanstalt (PTB), National Metrology Institute of Germany. This work is focused in a reproducible and close-to-ideal alignment position method of the SPAD detectors to the incident beam for achieving low measurement uncertainty.

Results: A dominantly Gaussian profile is obtained when the diameter of the detector is smaller than the beam diameter, whereas in case then the detector is larger than the beam, a dominantly rectangular scan is obtained. The optimal position (X/Y/Z) for setting the SPAD detector correspond to Xcenter = 235.11 mm, Ycenter = 6.28 mm and Zposition = 14.6 mm. Homogeneity of the detection efficiency depends on the beam size and evaluated regions.

Conclusions: The experimental set-up and experimental results needed for optimization of the SPAD detector position were described. This analysis gives important information in how to carry out the optimization of the detector position for the calibration of the SPAD and analysis of quantum detection homogeneity.
