Force decay and dimensional changes of thermoplastic and novel thermoset elastomeric ligatures
Authors: Masoud Ahmed I. , Bulic Milena , Viana Grace , Bedran-Russo Ana K.
Published: January 2016

Objectives: 

To compare over a period of 8 weeks (1) the force decay and (2) the dimensional changes between thermoplastic (TP) and thermoset (TS) elastomeric ligatures.

Materials and Methods: 

TP and TS elastomeric ligatures were obtained from Rocky Mountain Orthodontics™. The TS ligatures were custom made specifically for this study. The sample included 72 clear TP and 72 clear TS elastomeric ligatures. The experiment was performed in a simulated oral environment (pH of 6.75) at 37°C. The remaining forces and the dimensional changes were measured at different time points over a period of 8 weeks.

Results: 

Student’s t-tests revealed significant differences in percent force loss, percent change in outer diameter, percent change in inner diameter, and percent change in wall thickness between TP and TS elastomeric ligatures across all time points (P < .001). The difference in percent change in width between TP and TS elastomeric ligatures was not significant at all time points (P > .05). The mean difference in force loss between TP and TS across all time points was 22.91%. The TP and TS specimens exhibited 93.04% and 77.41% force loss, respectively, at the 28th day.

Conclusions: 

This novel TS elastomeric ligature showed significantly less force decay and dimensional changes over time; therefore, it might be superior during initial leveling and aligning and during finishing stages. Using a transfer jig to prevent relaxation of the specimens before force measurement showed that force decay of commercially available elastomeric ligatures was greater than that described in previous publications.
Probability of detection of minute defects by ultrasonic automated testing equipment in view of Bayesian inference
Authors: Leybovich Alex
Published: January 2016

The method of Bayesian analysis of confidence in the testing evidence collected during ultrasonic automated testing of high quality aluminum ingots for minute defects of sub-millimeter size is discussed. These test results are assessed in the view of true or false evidence. The analysis demonstrates the significant influence of false evidence on the confidence in the test outcome where the evidence is skewed in the direction of false positive. At the same time the influence of the false negative evidence is shown to be more muted. To minimize the risk of false rejection of ingots with “ghost” indications not representing the physical defects, the off-line ingot retesting by an A-scan with defect waveform verification is implemented. Retesting of fabricated blanks made of the ingots previously passed the ingot testing is used to minimize the risk of passing products with defects earlier undetected.
Direct and Indirect Impacts of Vegetation on Building Comfort: A Comparative Study of Lawns, Green Walls and Green Roofs
Authors: Malys Laurent , Musy Marjorie , Inard Christian
Published: January 2016

Following development and validation of the SOLENE-microclimat tool, the underlying model was used to compare the impacts of various “greening strategies” on buildings’ summer energy consumption and indoor comfort. This study distinguishes between direct and indirect impacts by successively implementing the test strategies on both the studied building and surrounding ones; it also considers insulated vs. non-insulated buildings. Findings indicate that green walls have a direct effect on indoor comfort throughout the entire building, whereas the effect of green roofs is apparently primarily confined to the upper floor. Moreover, the indirect effect of a green wall is greater, mainly due to the drop in infrared emissions resulting from a lower surface temperature. It has also been proven that the indirect effects of green walls and surrounding lawns can help reduce the loads acting on a non-insulated building.

The association between heavy metals exposure and respiratory diseases or allergic sensitization showing high serum immunoglobulin E (IgE) has been suggested. However, previous findings have been inconsistent and the mechanisms responsible remain unclear. We evaluated heavy metal exposure and its association with coughing, itchy eyes in chronic cough patients with different IgE levels. Ninety outpatients in Kanazawa University Hospital were recruited between January–June 2011. Subjects whose total IgE measured by radioimmunosorbent test were asked to record their daily symptoms. We collected daily total suspended particles (TSP) from which concentrations of calcium (Ca), cadmium (Cd), chromium (Cr), iron (Fe), manganese (Mn), nickel (Ni), and lead (Pb) were determined then divided into high and low level groups. Generalized estimating equations were applied to compute the relationship between concentrations of these metals and symptoms. All metals at high levels were significantly associated with itchy eyes compared with low levels, with exception of Ca, the six others were significant in patients with IgE < 250 IU/mL. Cd, Fe, Mn had association with coughing (odds ratio-OR (95% confidence interval-CI): 1.13 (1.03, 1.24), 1.22 (1.05, 1.42), and 1.13 (1.01, 1.27), respectively), this relationship remained significant for Cd (OR (95% CI): 1.14 (1.03, 1.27)) and Mn (OR (95% CI): 1.15 (1.00, 1.31)) in patients with lower IgE. Our findings demonstrate the relationship between aerial heavy metals and itchy eyes, coughing in chronic cough patients, suggesting these symptoms may be due to a non-IgE mediated mechanism.

Published: January 2016

Amentotaxus, a genus of Taxaceae, is an ancient lineage with six relic and endangered species. Four Amentotaxus species, namely A. argotaenia, A. formosana, A. yunnanensis, and A. poilanei, are considered a species complex because of their morphological similarities. Small populations of these species are allopatrically distributed in Asian forests. However, only a few codominant markers have been developed and applied to study population genetic structure of these endangered species. In this study, we developed and characterized polymorphic expressed sequence tag-simple sequence repeats (EST-SSRs) from the transcriptome of A. formosana. We identified 4955 putative EST-SSRs from 68,281 unigenes as potential molecular markers. Twenty-six EST-SSRs were selected for estimating polymorphism and transferability among Amentotaxus species, of which 23 EST-SSRs were polymorphic within Amentotaxus species. Among these, the number of alleles ranged from 1–4, the polymorphism information content ranged from 0.000–0.692, and the observed and expected heterozygosity were 0.000–1.000 and 0.080–0.740, respectively. Population genetic structure analyses confirmed that A. argotaenia and A. formosana were separate species and A. yunnanensis and A. poilanei were the same species. These novel EST-SSRs can facilitate further population genetic structure research of Amentotaxus species.
La genèse des crues élémentaires sut les marges du Bassin Aquitain
Authors: Viers Georges
Published: January 2016

L'étude des crues nécessite l'examen détaillé des situations météorologiques, y compris en altitude. Celui-ci montre que les causes des crues des rivières de l'Ouest du Massif central (Vézère et Viaur) et des Pyrénées atlantiques (Gave d'Aspe et Nive de Béhérobie) sont différentes et que leur synchronisme est extrêmement rare. La disposition du relief l'explique en grande partie et paraît donc à peu près exclu que la Garonne puisse subir l'effet conjugué de crues de ses affluents des Pyrénées et du Massif central.
Le père et le système d’attachement dans la famille contemporaine
Authors: Delage Michel
Published: January 2016

Le système motivationnel de l’attachement, tel qu’il a été étudié initialement mérité d’être complexifié. Il faut aujourd’hui le concevoir sous un angle triadique plutôt que dyadique. La place et le rôle du père méritent d’être mieux précisés, à la fois auprès de l’enfant et auprès de la mère. Des spécificités apparaissent et se dévoilent d’autant mieux dans les familles contemporaines. Cela n’est pas sans conséquences sur le travail thérapeutique dès lors qu’on inclut les connaissances sur l’attachement dans les approches familiales.

Lorsque la prison (se) rend justice
Authors: Fernandez Fabrice
Published: January 2016

À partir d’une enquête ethnographique menée sur une durée de 10 mois dans une maison d’arrêt de la région parisienne (en particulier l’observation de 81 jugements en commission de discipline), cette contribution vise à analyser et à questionner le contenu et le sens de la procédure disciplinaire en prison (du signalement d’incident à la réception des sanctions). Dans quel but sanctionne-t-on des détenus indisciplinés ? S’agit-il simplement de punir une conduite déviante et/ou de prévenir une récidive ? Au cœur de cette sanction, l’ordre n’est-il pas avant tout un ordre moral qui vise à transformer et rendre meilleurs les détenus ? Pour répondre à ce questionnement, je présente tout d’abord i) les enjeux politiques et moraux d’un traitement « humanisé » des indisciplinés, en retraçant les grandes réformes qui ont structuré la procédure disciplinaire. J’examine ensuite ii) les tensions entre les règles et les normes disciplinaires d’un côté et leur mise en pratique de l’autre en particulier à travers les décalages entre l’ordre moral des infractions et l’usage pragmatique des sanctions. J’analyse enfin iii) comment la commission de discipline est un espace de négociation au sein duquel les valeurs et les affects se conjuguent à des formes d’évaluation de la personnalité des détenus. À partir de l’ensemble de ces éléments, je montre comment malgré un souci d’humanisation, cette procédure disciplinaire produit de nouvelles formes de domination et de violence symbolique (infantilisation, responsabilisation, rectification morale).

Drawing on the experience of internationalization of an Italian Small Medium Enterprise, this chapter provides some insights over the challenges experienced by developing countries and newly industrialized countries to attract foreign investments for the establishment of the industry. The study relies on a structured research protocol where primary data was collected from several interviews with the firm and European space agencies.
Turkey's Participation and Economic Upgrading in Global Value Chains
Authors: Ozer Seda Koymen , Taglioni Daria , Winkler Deborah
Published: January 2016

This chapter assesses Turkey's position in global value chains (GVCs) and identifies the conditions under which the country can better exploit the advantages from GVC participation, in particular how the country can economically upgrade its GVC position by reaping the benefits of spillovers to the domestic economy. The chapter reviews Turkey's participation in three key industries: the automotive sector, the textiles and apparel sector, and the agri-food sector. The results show that Turkey is relatively present in GVCs. However, the country seems to specialize in assembly and low value added segments of the value chain. It is also important to evaluate the spillovers from foreign direct investment (FDI) to the domestic economy. The results show that high R&D expenditure and/or a high technological intensity are beneficial for Turkey's manufacturing firms. In addition, supplying fully foreign-owned companies significantly helps boost the productivity of domestic firms.
The Role of Securitization Market in the Post-Crisis European Economic Recovery
Authors: Karnaukhova Oxana , Nekrasova Inna
Published: January 2016

European national economies begin to recover, and securitization can play an important role in supporting both monetary and financial stability. In particular, securitization may allow banks to lend without over-committing of the capital and other sources of funding, and thereby to provide indirect market access to borrowers. Otherwise, such borrowers as SME's are not able to tap markets directly. At the same time securitization suffers from stigma, reflecting both its adverse reputation among investors and conservatism among regulators and standard-setters. This is the consequence of misaligned incentives in years prior to the financial crisis, when industry participants became entwined in a self-reinforcing dynamic between demand and supply of securitizations. Using data accessible within the period of 2009-2014, the chapter will input by the analysis of transformation in the securitization market within the post-crisis economic recovery of the EU.

Authors: Rivlin Paul
Published: January 2016

This chapter examines the stabilization programs of 1985, 2003, other changes in fiscal policy and the liberalization of the Israeli economy. These programs have had dramatic effects in terms of reducing inflation, encouraging growth and improving the balance of payments and the structure of the economy. At the same time, they have reduced the role of the state and have been accompanied by growing inequality and an increase in relative poverty that resulted in an increase in transfers to households and a squeeze on other public spending.

Authors: Geetha M. Kalaiselvi , Arunnehru J. , Geetha A.
Published: January 2016

Automatic identification and early prediction of suspicious human activities are of significant importance in video surveillance research. By recognizing and predicting a criminal activity at an early stage, regrettable incidents can be avoided. Initially, an action recognition framework is developed for identifying the suspicious actions using interest point based 2D and 3D features and transform based approaches. This is subsequently followed by a novel approach for predicting the suspicious actions for crime prevention in real-world scenario. The prediction problem is formulated probabilistically and a novel approach that employs the mixture models for prediction is introduced. The developed system yields promising results for predicting the actions in real-time.

Published: January 2016

Deployment of human gait in developing new tools for security enhancement has received growing attention in modern era. Since the efficiency of any algorithm depends on the size of search space, the aim is to propose a novel approach to reduce the search space. In order to achieve this, the database is split into two based on gender and the search is restricted in the identified gender database. Then highly discriminant gait features are selected by forward sequential feature selection algorithm in the confined space. Experimental results evaluated on the benchmark CASIA B gait dataset with the newly proposed combined classifier kNN-SVM, shows less False Acceptance Rate (FAR) and less False Rejection Rate (FRR).

Sociocultural Impacts of Sport Event Tourism in Mexico
Authors: Monterrubio Carlos
Published: January 2016

Sport event tourism has been acknowledged as a potential agent of economic and sociocultural change in host destinations. The existing literature provides evidence that the impacts of sport events are extensively shaped by not only the type and magnitude of the events but also by the conditions of the destinations in question. By recognising that most of the empirical evidence on the sociocultural impacts of sport event tourism has been drawn from case studies in Western, developed countries, this paper suggests that the experiences of developing countries need to be incorporated into the general body of knowledge on this area. The paper then explores potential research needs and opportunities for the study of sociocultural impacts of sport event tourism in Mexico that could contribute to the general advancement of the theoretical and conceptual underpinning of sport event tourism's impacts.

La memoria nostálgica a través de Internet y de las Historias de vida: Confrontaciones generacionales de las historias de barrio
Authors: Berruga Sánchez Lucia
Published: January 2016

Los barrios, como espacios cargados de señales de identidad, son uno de los focos creadores del recuerdo personal. Se analiza el barrio de la Ciudad de los Ángeles, en Madrid (España), como generador de vivencias personales bajo la hipótesis de que los recuerdos obtenidos serán de tipo nostálgico, no traumático. A través de una confrontación generacional y una separación metodológica entre los testimonios orales autobiográficos de las historias de vida individuales y las publicaciones de los usuarios en la comunidad virtual, se pretende concluir con que la representación de la memoria de distintas generaciones en la red social crea, a diferencia de las historias de vida, un recuerdo colectivo, en vez de individual.

Published: January 2016

O uso de medicamentos faz parte do quotidiano de muitas crianças com doença crônica ou doenças agudas recorrentes. O objetivo desta pesquisa foi avaliar o potencial cariogênico de anti-histamínicos de uso pediátrico. Cinco medicamentos anti-histamínicos foram avaliados in. Foi determinado pH dos medicamentos, a concentração de sólidos solúveis(ºBrix) e a determinação do teor de açúcares totais. Verificou-se que todos dos medicamentos apresentaram pH menor que 5,5, sendo portanto, ácidos e potencialmente cariogênico aos tecidos dentais. Em relação aos sólidos solúveis totais (ºBrix) a dexclorfeniramina apresentou o menor valor de ºBrix (10,4%) e o cetotifeno, o maior valor de ºBrix (60,4%). No tocante aos açúcares totais, o percentual variou de 2,28% (cetotifeno) a 16,76% (loratadina). Os anti-histamínicos analisados têm um alto potencial cariogênico, visto que possuem um baixo pH e elevado teor de sólidos solúveis totais. Torna-se imprescindível, portanto, que haja uma atenção maior sobre o tema, objetivando que os profissionais de saúde reconheçam a possível relação entre o uso de medicamentos pediátricos e cárie dentária, a fim de que possam orientar adequadamente os responsáveis sobre os cuidados necessários para minimizar possíveis efeitos deletérios na saúde oral de pacientes infantis.
QUANTIFICAÇÃO DE ?-SITOSTEROL LIVRE E DE FITOESTERÓIS TOTAIS NO ÓLEO DE Dipteryx alata Vogel (BARU)
Authors: Marques Fernanda Garrote , Oliveira Neto Jeronimo Raimundo , Cunha Luiz Carlos , Freitas Bara Maria Teresa
Published: January 2016

O baru (Dipteryx alata Vog. família Fabaceae) é uma planta típica do cerrado cujo óleo extraído das sementes é usado popularmente como anti-reumático e regulador da menstruação. O interesse em avaliar fitoestérois em óleos vegetais deve-se a sua aplicação na prevenção de dislipidemias, de doenças cardiovasculares e à sua atividade na proteção contra tumores estimulados por estrogênio. O presente trabalho teve como objetivo contribuir com o conhecimento químico da espécie, de modo particular, em relação ao conteúdo em fitoesteróis livres e totais. Foi necessário desenvolver e validar um método analítico por CG-EM para a quantificação do ?-sitosterol livre no óleo de baru. A concentração dos demais fitoesteróis foi estimada utilizando suas áreas relativas no cromatograma. Para quantificar os fitoesteróis totais foi realizada uma saponificação branda do óleo, a temperatura ambiente, a fim de hidrolisar a ligação de esterificação e os fitoesteróis liberados serem então quantificados. A concentração de fitoesteróis totais foi de 1696,31 mg/kg e foram identificados campesterol, estigmasterol, ?-sitosterol e cicloartenol.

Published: January 2016

O consumo de água mineral tem apresentado um crescimento devido à desconfiança da população em relação a água potável que muitas vezes apresenta odor e sabor desagradáveis. Sabe-se que a água mineral não é estéril e pode apresentar contaminação se não houver cuidados no seu envase nas indústrias. O objetivo desde trabalho foi avaliar a qualidade microbiológica da água mineral (envasada em garrafões de 20 litros), comercializada no município de Itabuna, Bahia, Brasil, no período de fevereiro a abril de 2012. Os microrganismos pesquisados pela Técnica da Membrana Filtrante foram Coliformes totais, Escherichia coli e Pseudomonas aeruginosa. Também foi avaliada a presença de enterobactérias, nas superfícies dos garrafões, pela Técnica de Esfregaço em Superfície. Os resultados foram interpretados com base na Resolução RDC nº 275 de 2005. Das 18 amostras analisadas, 44,5% apresentaram resultados positivos para Coliformes totais e 50% apresentaram contaminação por Pseudomonas aeruginosa. Uma única amostra (5,6%) apresentou positividade para Escherichia coli. A análise de enterobactérias evidenciou contaminação superficial dos garrafões em 83,3% das amostras. Os resultados evidenciaram que 13 amostras de água mineral apresentavam-se em condições impróprias para consumo, considerando os microrganismos estudados, e demonstraram a importância da higienização correta das superfícies dos garrafões.
From Colored Cosmopolitanism to Human Rights: A Historical Overview of the Transnational Black Freedom Struggle
Authors: Slate Nico
Published: January 2016

The last twenty years have witnessed an outpouring of scholarship on the transnational dimensions of the African American freedom struggle. Drawing on that scholarship, this essay offers a synthetic overview of the global civil rights movement from two specific and distinct lenses: human rights and colored solidarity. Beginning in the 1920s, notions of a dark or colored world connected African Americans to anti-imperial and antiracist movements abroad. In the 1950s and 1960s, solidarities based on notions of color were gradually replaced by a human rights framework and a new focus on the third world. The colored world lost its centrality as the leaders of postcolonial nations turned away from global antiracism toward state-centered visions of international relations. After 1968, however, colored cosmopolitanism experienced a resurgence within the United States as a result of shifting patterns of migration. On the global scale, by contrast, notions of human rights emerged triumphant in the discourse of international organizations and in the popular imagination of many countries. The achievement of those rights remains, however, woefully incomplete. While the promise of the colored world failed to survive decolonization, the promise of human rights endures more as a goal than a reality.

Authors: Francisco João Domingos da Silva , Claro José Alberto Carvalho dos Santos
Published: January 2016

O presente estudo teve como objetivo geral analisar as relações entre estas três variáveis: ‘satisfação no trabalho, comprometimento organizacional afetivo e intenção de rotatividade’. Ligando-se aos objetivos através dos seus estímulos internos ou externos, desvendados no estudo em uma mineradora de diamantes em Angola onde foram analisadas as relações entre as três variáveis. Participaram na pesquisa 151 trabalhadores, todos de nacionalidade angolana selecionados aleatoriamente em diferentes áreas da empresa. O tratamento dos dados, de natureza quantitativa, foi processado pelo software estatístico Statistical Package for the Social Science – SPSS, versão 19.0 para Windows. Os resultados descritivos indicam que os trabalhadores detêm um quadro de satisfação no trabalho, com satisfações maiores proporcionadas pelo número de vezes e oportunidades de serem promovidos, com a capacidade profissional de seus chefes, no entendimento encontrado entre si e na maneira como são tratados pelos seus chefes; e menores com o tipo de amizade, confiança e espírito de colaboração demonstrada pelos seus colegas de trabalho, assim como com a capacidade absorvida e o salário se comparado com o quanto trabalha. O quadro do comprometimento organizacional afetivo demonstra maior afeto as questões relacionadas a empresa em fazer o empregado sentir-se orgulhoso e contente com ela. Análises de correlação pelo r de Pearson informaram índices negativos e significativos entre as duas variáveis e intenção de rotatividade. Tais resultados informam que o plano de deixar a empresa onde trabalham é cada vez menor à medida que se elevam os níveis de satisfação no trabalho e comprometimento organizacional afetivo.
Análise do desempenho dos filtros de Graham e o modelo de Elton-Gruber para o Brasil entre 2008 a 2012
Authors: Ferreira Romualdo Luis da Silva , Santos David Ferreira Lopes
Published: January 2016

Os pensamentos de Graham e de Elton-Gruber têm a finalidade de orientar a seleção de ativos no mercado de capitais, estabelecendo critérios para que se possam escolher ativos para compor uma carteira de investimentos. O objetivo deste estudo é comparar a eficiência em performance de uma carteira gerada pela aplicação dos filtros de Graham e outra originada do emprego dos preceitos do modelo de Elton-Gruber, tendo como escopo ações ordinárias listadas na BM&FBOVESPA, no período que vai de 2008 a 2012. Utilizou-se uma abordagem metodológica quantitativa exploratória. Pela aplicação dos filtros de Graham foram selecionadas as ações Bradesco (BBDC3), Copasa (CSMG3) e Cremer (CREM3), formando a Carteira A. Pelo método de Elton-Gruber foram selecionas as ações Santanense (CTSA3), PetManguinhos (RPMG3), AES Elpa (AELP3), Le Lis Blanc (LLIS3) e Marcopolo (POMO3), constituindo-se a Carteira B. O desempenho das carteiras foi analisado por meio dos índices de risco/retorno: CAPM, Índice de Sharpe (IS), Índice de Treynor (IT), Alfa de Jensen, Information Ratio (IR) e o Índice de Modigliani-Modigliani (M²). Ao final do período constatou-se que dos seis indicadores analisados a Carteira A mostrou-se mais vantajosa em quatro. Entretanto, as duas carteiras apresentaram índices bem próximos. As diferenças existentes entre as duas carteiras assumiriam assim diferentes significados de acordo com o perfil do investidor. A Carteira B apresentou um retorno maior, porém, um risco mais alto que a Carteira A. A Carteira B seria um investimento mais adequado a um investidor de perfil mais agressivo, enquanto que a Carteira A serviria melhor as expectativas de um investidor conservador.

Tryptophan‐rich antigens of malarial parasites interact with host molecules and play an important role in parasite survival. Merozoite expressed Plasmodium vivax tryptophan‐rich antigen PvTRAg38 binds to human erythrocytes and facilitates parasite growth in a heterlologous Plasmodium falciparum culture system. Recently, we identified band 3 in human erythrocytes as one of its receptors, although the receptor‐ligand binding mechanisms remain unknown. In the present study, using synthetic mutated peptides of PvTRAg38, we show that multiple amino acid residues of its 12 amino acid domain (KWVQWKNDKIRS) at position 197–208 interact with three different ectodomains of band 3 receptor on human erythrocytes. Our findings may help in the design of new therapeutic approaches for malaria.
Crystal structures of penicillin‐binding protein 3 in complexes with azlocillin and cefoperazone in both acylated and deacylated forms

Penicillin‐binding protein 3 (PBP3) from Pseudomonas aeruginosa is the molecular target of β‐lactam‐based antibiotics. Structures of PBP3 in complexes with azlocillin and cefoperazone, which are in clinical use for the treatment of pseudomonad infections, have been determined to 2.0 Å resolution. Together with data from other complexes, these structures identify a common set of residues involved in the binding of β‐lactams to PBP3. Comparison of wild‐type and an active site mutant (S294A) showed that increased thermal stability of PBP3 following azlocillin binding was entirely due to covalent binding to S294, whereas cefoperazone binding produces some increase in stability without the covalent link. Consistent with this, a third crystal structure was determined in which the hydrolysis product of cefoperazone was noncovalently bound in the active site of PBP3. This is the first structure of a complex between a penicillin‐binding protein and cephalosporic acid and may be important in the design of new noncovalent PBP3 inhibitors.
