Published: October 2019

Modification of Ti–6Al–4V alloys with silver-loaded TiO2 nanotubes was investigated. In this study, TiO2 nanotube (TiNT) was grown on the surface of Ti–6Al–4V plates by means of anodization in an electrolyte solution containing glycerol, water and 0.5[Formula: see text]wt.% of NH4F. Silver particles were deposited on TiNT using a Photo-Assisted Deposition (PAD) method. Formation of crystalline phase of TiO2 on the surface was confirmed by means of XRD while its superficial morphology was observed using FESEM/EDS. Hydrophilicity was assessed by means of contact angle measurement. As-synthesized silver-loaded TiNT on osteoblast ATCC growth in vitro was also investigated in terms of its capacity in supporting osseointegration. The cell viability was determined by MTT (3-[4,5-dimethylthiazol-2yl]-2,5diphenyl-2H-tetrazolium bromide) assay and its differentiation activity was measured by alkaline phosphatase (ALP) assay. The results showed that desposition of silver on TiNT increased cell viability after 14 days culture while improving the hydrophilicity feature. Silver-loaded TiNT on Ti–6Al–4V alloy with Ag precursor concentration of 0.10[Formula: see text]M showed the optimum viability of osteoblast growth, with 14% improvement in comparison to its unmodified counterpart. The MTT assay showed that no cytotoxicity in vitro was observed on this material. This study provides corroborating evidences that the modification of Ti–6Al–4V alloy may enhance the cell viability and its prominence as dental implant materials.

O objetivo do presente estudo foi detectar parasitos com potencial zoonótico em fezes de cães no entorno de escolas municipais de educação infantil, no município de Pelotas, RS, Brasil. Foram coletadas 111 amostras em 22 escolas, procedentes de cinco bairros do referido município. As fezes foram processadas pelo método de Willis-Mollay (1921). Dentre as amostras testadas, 76/111 (68,47%) apresentaram-se positivas para algum gênero de parasito. Sendo que 41 (53,95%) apresentaram infestação única e 35 (46,05%) apresentaram múltiplos parasitos. Ancylostomafoi o gênero prevalente nas amostras de todos os bairros, com 61,27% do total analisado. O bairro com maior percentual de amostras positivas foi o Areal, 93,55% enquanto o Centro com 47,06% teve a menor porcentagem. Por ser um local com circulação frequente de pessoas, especialmente crianças, a presença de ovos de helmintos com potencial zoonótico caracteriza um risco para a população, sendo necessário adotar medidas sanitárias com a finalidade de reduzir tal exposição.

A Staphylococcus Multiplex PCR system was developed for the simultaneous detection of the mecA, mecC, blaZ (resistance genes of b-lactam resistance) and PVL (pathogenicity factor gene), associated with an internal reaction control with the 16S rRNA gene. There were used primers described in the literature with and without modification and designed primers to standardize the hybridization and amplification temperature of distinct bands with 139 bp (mecC), 228 bp (16S), 313 bp (mecA), 408 bp (PVL) and 516 bp (blaZ) of molecular weight. The standardization was performed in ATCC strains and Staphylococcus schleiferiand tested in 56 strains of Staphylococcusspp. The 16S gene (internal control) was amplified in all samples, mecA gene was detected in two samples, mecA associated with mecC gene in one sample, mecA associated to the blaZ gene in 14 samples and the blaZ gene in 15 samples. No resistance genes were amplified in 24 samples. The PVL gene was not amplified in any of the samples tested.

Published: October 2019

Trata-se de um estudo descritivo. Os dados foram obtidos no Sistema de Informação de Agravos de Notificação (SINAN). Teve como finalidade descrever a epidemiologia da leptospirose humana em Santa Catarina, nos últimos cinco anos. Os dados foram estratificados de acordo com as variáveis: sexo, faixa etária, zona de residência, critério de confirmação do diagnóstico, evolução da doença e possível ambiente da infecção. A leptospirose é uma zoonose infecciosa e aguda, causada pela bactéria Leptospira. Ela infecta tanto o homem quanto animais e tem distribuição mundial, tanto na área rural como na urbana. A infecção humana pode ocorrer por contato com água ou solo contaminados, principalmente durante chuvas e enchentes. Em Santa Catarina, durante o período de 2012 a 2017, foram notificados 2312 casos, sendo mais atingidos os homens e a faixa etária de 20 a 59 anos. 45,54% dos casos ocorreram em área urbana e 37,76% em área rural. O ambiente onde mais ocorreu a infecção foi o domiciliar (41,35%). Ainda, 95% dos casos confirmados tiveram diagnóstico clínico-laboratorial. A evolução de 92,73% dos casos foi a cura e em 2,81% deles houve óbito pela doença (letalidade). A maior porcentagem de óbitos ocorreu na faixa etária <1 ano (10,53%) e na faixa etária 70-79 (9,09%). O município que apresentou maior número de casos confirmados foi Joinville (10,25%). Observou-se uma maior ocorrência de casos nos meses de janeiro, fevereiro, março e abril.

Published: October 2019

Abstract
As per the latest roadmap of iNEMI, the global electronics market is emphasizing to identify disruptive technologies that can contribute towards denser, robust and tighter integration on the board level. Therefore, reduction in packaging factor of printed board can accommodate greater number of ICs to support miniaturization. This paper has shown an experimental method to pattern the metallic layer on a Printed circuit Board (PCB) to the smallest feature size. To investigate this, a commercially available FR-4 PCB with photosensitive material coat and a Copper (Cu) layer on it, is used. A reverse-mode Laser assisted writing is implemented to pattern the desired copper tracks. Soon after, a well-controlled development and chemical etching of the Laser-activated regions are done using Sodium Hydroxide solution followed by an aqueous solution of Sodium Persulfate. Current PCB interconnects used by the industries are of the order (~20 μm). Whereas the present work is a contribution towards achieving Copper interconnects with feature size 3.0μm. This miniaturization corresponds to 70% reduction in the feature size from 20 μm to 3 μm. The natural adhesion of the Cu layer has remained intact even after the etching, shows the efficiency of the method adopted. Also, variation in the parameters such as etching time, etchant solution concentrations, temaperature, gain and exposure time of Laser beam and their corresponding effects are discussed. Other highlights of this subtractive method includes its cost-efficiency, lesser production time and repeatability.
Cystic fibrosis and the role of the physiotherapist
Authors: Miot Anne , Pettifor J. M. , Reef I. 
Published: October 2019

Cystic fibrosis is an inherited disease, the major problems being pancreatic malabsorption and progressive respiratory involvement, although numerous other organs may also be involved. The pulmonary pathology and the role of the physiotherapist in the treatment of cystic fibrosis is discussed. The physiotherapist plays an important role in the management of the child with cystic fibrosis, not only from the point of view of maintaining maximal pulmonary function but also because she comes into close contact with the family and can help in optimising the acceptance of the child into the family situation.
Positive Definiteness on Products of Compact Two-point Homogeneous Spaces and Locally Compact Abelian Groups
Authors: Menegatto V. A. , Oliveira C. P. 
Published: October 2019

AbstractIn this paper, we consider the problem of characterizing positive definite functions on compact two-point homogeneous spaces cross locally compact abelian groups. For a locally compact abelian group $G$ with dual group $\widehat{G}$, a compact two-point homogeneous space $\mathbb{H}$ with normalized geodesic distance $\unicode[STIX]{x1D6FF}$ and a profile function $\unicode[STIX]{x1D719}:[-1,1]\times G\rightarrow \mathbb{C}$ satisfying certain continuity and integrability assumptions, we show that the positive definiteness of the kernel $((x,u),(y,v))\in (\mathbb{H}\times G)^{2}\mapsto \unicode[STIX]{x1D719}(\cos \unicode[STIX]{x1D6FF}(x,y),uv^{-1})$ is equivalent to the positive definiteness of the Fourier transformed kernels $(x,y)\in \mathbb{H}^{2}\mapsto \widehat{\unicode[STIX]{x1D719}}_{\cos \unicode[STIX]{x1D6FF}(x,y)}(\unicode[STIX]{x1D6FE})$, $\unicode[STIX]{x1D6FE}\in \widehat{G}$, where $\unicode[STIX]{x1D719}_{t}(u)=\unicode[STIX]{x1D719}(t,u)$, $u\in G$. We also provide some results on the strict positive definiteness of the kernel.

Published: October 2019

This study used thespatially integrated RUSLE to estimate annual soil loss and spatial distribution of soil loss severity classes for nine (9) reservoir catchments in northern Ghana.This model is an empirical model with five (5)main input parameters: rainfall erosivity, soil erodibility, slope length/steepness, landcover management and erosion management practice factors. Estimated annual soil loss rate ranged from 0 – 96.30 t/ha/y. Estimated mean annual soil loss ranged from 3.71 – 8.17 %. The severity of annual soil loss rates ranged from very low class (0.0 – 1.0 t/ha/y) to very high class (> 60.0 t/ha/y). Across the nine (9) catchments, the very low soil loss severity class was noted to constitute a larger portion of between 36.70 to 67.50 %. The moderate soil severity class was noted as the highest contributor to total annual soil loss. Soil and water conservation measures are required in the watershed to reduce soil loss.

Teatralidades da linguagem e poesia contemporânea
Authors: Scramim Susana 
Published: October 2019

Este artigo pretende discutir os processos de nomeação operados pela escrita contemporânea, especialmente, no trabalho de duas poetas, Paula Glenadel e Nathalie Quintane, em seus livros respectivamente, A fábrica do feminino (2008) e Chaussure (1997). Serão tomados em consideração nesta reflexão os gestos que formulam definições, aplicam atributos, criam tropismos e, simultaneamente, os desconstroem, na medida que colocam o próprio processo de nomeação em xeque nessa experiência de escrita. Com isso, se estabelece uma relação entre voz (querer dizer) e linguagem (ser obrigado a dizer) que implica o enfrentamento de uma das formulações mais radicais da poesia moderna, a saber, reelaborar a relação entre a escrita da poesia – do verso – e a produção de um pensamento que se mantenha ético. Esse processo de nomeação e renomeação será denominado aqui de teatralidades da linguagem.
The Stature of Volunteers to the Polish Army in France: An Anthropometric Inquiry
Authors: Kopczyński Michał , Antosik Szymon 
Published: October 2019

Abstract
This article analyzes the stature of volunteers to the Polish Army in France examined in Recruitment Center no. 2 in Chicago in 1917 and 1918. The authors divided the sample according to place and time of birth and compared the statures of volunteers with heights of Polish draftees measured by conscription authorities in Poland. The investigation arrives at two main conclusions. Firstly, Poles born in the US were considerably taller than both volunteers born in Poland and draftees living in the native country. Secondly, the comparison of immigrants and those who remained in Poland shows that people who migrated were taller than those who remained, although the difference diminished over time. Since human stature is positively correlated with length of life and work capacity, we can conclude quoting the opinion of the Dillingham Commission: Although drawn from classes low in the economic scale, the new immigrants as a rule are the strongest, the most enterprising, and the best of their class.
Expectancy-Value Theory of Achievement Motivation: How Perceived Racial Prejudice Can Influence Ability Beliefs, Expectancy Beliefs and Subject Task Value of Métis Post-Secondary Students
Authors: Ferguson Leon Myles 
Published: October 2019

To explore how the threat of prejudice can interfere with a learner’s ability beliefs, expectancies of success and subjective task value 165 Métis post-secondary students were asked to consider themselves applying for a job with a non-Indigenous employer. Participants were grouped into high and low Métis identifiers and then placed into one of three groups: (1) Employer-prejudiced, (2) Employer non-prejudiced, and (3) Employer’s attitudes about Indigenous peoples unknown. A 2x3 Analysis of Variance (ANOVA) was used to examine the relationship between Métis identity (high/low) and five concepts: (1) expectations about being hired, (2) value placed on being hired, (3) learners’ beliefs about the mock employer’s integrity, (4) the extent to which learner’s held negative over-generalized negative beliefs about non-Indigenous people, and (5) actual task performance. Although there were no interaction effects a number of main effects are reported. While students with a stronger sense of Métis identity reported more overall optimism about being hired that those learners with a weaker sense of Métis identity, they nevertheless reported less motivation to perform an assigned task to the best of their respective abilities. Students in the prejudiced condition reported lower expectations about being hired and less motivation to perform the assigned task to the best of their ability. Students in the prejudiced condition also reported stronger negative generalized beliefs about both the mock employer and non-Indigenous people in general. Although the students in the prejudiced condition reported less motivation to exert high effort on the assigned task, their actual performance on the task was not related to whether or not the hypothetical employer was described as prejudiced, non-prejudiced, or neither about Indigenous peoples. Future studies should explore how one’s sense of Métis identity and other minority group identity can influence reactions to a threatening academic environment and suppress academic motivation.
Efectos del contenido de meta docente y la regulación motivacional académica sobre la creencia de eficacia docente del profesorado en formación inicial
Authors: Burgueño Rafael , Sicilia Álvaro , Alcaraz-Ibáñez Manuel , Lirola María-Jesús , Medina-Casaubón Jesús 
Published: October 2019

Introducción: Basado en la Teoría de la Auto-Determinación, el objetivo del estudio fue examinar la relación entre los contenidos de meta y la creencia de la eficacia docente en profesorado en formación inicial, considerando el rol mediador de la regulación motivacional académica (autónoma y controlada) al inicio y final del master de formación del profesorado. Método: Los participantes fueron 379 profesores/as en formación inicial (180 hombres y 199 mujeres; Medad = 25.30, DT edad = 4.21) quienes completaron medidas de contenidos de meta en la docencia y regulación motivacional académica al inicio del máster en formación del profesorado (toma 1), así como medidas de regulación motivacional y creencia de eficacia docente al final del máster (toma 2). Las relaciones predictivas hipotetizadas fueron examinadas vía análisis de ecuaciones estructurales. Resultados: El modelo de ecuaciones estructurales mostró que los contenidos de meta intrínsecos al inicio del máster de formación del profesorado tuvieron un efecto positivo directo sobre la creencia de la eficacia docente al final del máster, estando dicha relación mediada por la motivación autónoma académica al inicio y al final del máster. En cambio, los contenidos de meta extrínsecos al inicio del máster de formación del profesorado mostraron un efecto directo y negativo sobre la creencia de la eficacia docente al final del máster. Discusión: Los resultados obtenidos subrayan la relevancia del contenido de meta en la explicación de la naturaleza dinámica de los procesos motivacionales relacionados con la creencia de eficacia docente durante el programa inicial de formación docente del profesorado en formación inicial.
Cuatro calas en la novela española actual: Esther GarcÍa llovet, Mario Cuenca Sandoval, Andrés Neuman y Aroa Moreno Durán
Authors: Valls Fernando 
Published: October 2019

La novela española actual, la que ha surgido en el siglo XXI, está dando frutos muy diversos en sus distintos registros estéticos, lingüísticos y temáticos. Buena prueba de ello son las cuatro narraciones de las que aquí nos ocupamos. La aceleración de la historia actual, junto con los conflictos relativos a la vida cotidiana proporcionan al narrador de nuestros días materia más que suficiente para que, a través de la ficción, podamos comprender algo mejor nuestro mundo, ya se trate del presente, ya del pasado que sigue condicionándonos.
The current Spanish novel, which has emerged in the 21st century, is bearing very different fruits in its different aesthetic, linguistic and thematic registers. Good proof of this are the four narrations that we are dealing with here. the acceleration of current history, together with the conflicts related to everyday life, provide the narrator with more than enough material so that, through fiction, we can understand our world better, whether it is the present, past that continues conditioning us.
Un palimpsesto indeseado en la obra literaria de Juan benet: Julio Cortázar y sus minúsculas pedanterías.
Authors: Machín Lucas Jorge 
Published: October 2019

Se estudia la influencia de Julio Cortázar en Juan Benet, partiendo de las entrevistas hechas a este último. Este lo criticó con virulencia y superficialmente pero, tras un estudio comparativo de sus respectivas obras literarias, se han advertido una serie de concomitancias entre ellos. Ambos relativizaron y descentraron los conceptos de realidad, de lógica y de tiempo y sus instrumentales epistemológicos, narratológicos o lingüísticos. Lo hicieron para elevar el nivel intelectual de los lectores y para así poder penetrar más en lo irracional, espacio de una razón «ultraperceptible» útil para nuestra evolución.
I study Julio Cortázar´s influence in Juan Benet, based on the interviews made to the latter. He criticized him with virulence and superficially but, after a comparative study of their respective literary works, I found some similarities between both of them. they minimized and decentered the concepts of reality, logic and time as much as they did it with their epistemological, narratological or linguistic tools. they did that in order to raise the intellectual level of the readers and so as to penetrate more in the irrational, the space of a reason beyond perception and useful for our evolution.
Se construire en situation de pauvreté et de raccrochage scolaire : une approche biographique
Authors: Charlebois François-Xavier 
Published: October 2019

Cet article présente les épreuves sociales vécues par dix jeunes adultes en situation de pauvreté et de raccrochage scolaire. L’analyse des rapports sociaux constitutifs de leur histoire de vie a permis de formaliser une compréhension du processus de construction identitaire de chacune et de chacun de ces jeunes adultes. Pour plusieurs, l’expérience du raccrochage scolaire apparaît comme une voie pour réussir une période de moratoire et s’émanciper de rapports sociaux qui ont inhibé la construction de leur identité. Cet article permettra aussi d’identifier les contraintes persistantes à l’émancipation à un moment où ils cherchent à entrer positivement dans l’âge adulte alors qu’ils vivent en situation de pauvreté.
La mendicité comme moyen de revendication d’une identité positive : l’exemple des « mères de jumeaux » à Ouagadougou
Authors: Sawadogo Honorine Pegdwendé 
Published: October 2019

Cet article présente les résultats d’une étude visant à comprendre le sens de la pratique de la mendicité par des « mères de jumeaux » en contexte urbain. Elle s’appuie sur des entretiens individuels menés auprès de 30 « mères de jumeaux » en situation de mendicité dans la ville de Ouagadougou. Les résultats révèlent que la présentation des jumeaux est un fait culturel pour certains groupes socioculturels qui considèrent les jumeaux comme des enfants exceptionnels. La mendicité telle que pratiquée actuellement par des « mères de jumeaux » répond donc à des codes culturels, mais l’urbanisation lui impose une mutation pour la satisfaction des besoins existentiels. Cette nouvelle forme de mendicité reflète une des stratégies alternatives mises en oeuvre par ces femmes pour survivre et faire vivre leur famille. En subvenant aux besoins de leur famille, elles se sentent utiles et s’identifient comme des mères vaillantes et résilientes.
PORTRAIT DES PRATIQUES LIÉES À L’USAGE DU STANFORD PRESENTEEISM SCALE (SPS-6) EN RECHERCHE : UNE ÉTUDE COMPARANT LES PROPRIÉTÉS DE TROIS VERSIONS DIFFÉRENTES DE L’INSTRUMENT
Authors: Lauzier1 Martin 
Published: October 2019

Cette étude effectue un portrait des pratiques liées à l’usage du Stanford Presenteeism Scale (SPS-6) en recherche, un instrument couramment utilisé dans les travaux sur le présentéisme. Deux cent trente-huit travailleurs divisés en trois groupes ont participé à l’étude : un complétant le questionnaire dans sa version originale et les autres répondants aux deux versions expérimentales (l’une dont les items sont de forme positive et l’autre dont les items sont de formes négatives). Les résultats montrent que les versions expérimentales présentent des structures unidimensionnelles et des patrons corrélationnels similaires à ceux de la version originale. Des guides à l’usage des différentes versions du SPS-6 sont discutés en conclusion.
EXCESSIF, ADDICTIF, COMPULSIF, HYPERACTIF : RELATIONS ENTRE EXERCICE ET TROUBLE DES CONDUITES ALIMENTAIRES À L’ADOLESCENCE
Authors: Fortier Martine , Dion1 Jacinthe 
Published: October 2019

Cet article vise une meilleure compréhension de l’exercice compulsif : sa définition, son développement selon les théories existantes et son lien avec les troubles des conduites alimentaires (TCA). Pour ce faire, les différentes définitions et les termes liés à l’exercice compulsif sont décrits, de même que les théories et modèles récemment élaborés pour comprendre ce lien. Suite à la présentation des différents concepts, le terme « exercice compulsif » est particulièrement adapté pour décrire le lien entre l’exercice et les TCA. La compulsion, le perfectionnisme et la rigidité semblent des facteurs communs à l’exercice compulsif et aux TCA tant dans les modèles psychologiques que ceux découlant des neurosciences. Une attention est enfin portée aux particularités liées à l’exercice compulsif à l’adolescence.
