Characterization of Recycled Silk Fiber PP Composites with Optimal Performance of Silk Fibers by Response Surface Methodology
Authors: Rajkumar G. , Srinivasan J.
Published: December 2018

This article emphasizes the optimization of the retrieval of silk fibers from silk selvedge waste in a hard waste opening machine. It also highlights the characterization of composites developed from retrieved silk fibers with a polypropylene matrix in a compression molding machine. The machine conditions of the hard waste opener, such as the licker-in speed, cylinder speed, and setting between feed roller to licker-in, were optimized with respect to the fiber staple length using the Box-Behnken experimental design with response surface methodology. The optimum conditions for the fiber staple length were found to be licker-in speed, 550 r/min; cylinder speed, 280 r/min; and setting between feed roller to licker-in, 0.01 inch. Composites were developed using the silk fibers retrived at optimum conditions with polypropylene resin in compression molding at three different fiber loadings, namely 40, 50, and 60 weight % of silk fibers. The influece of silk fiber loading on the mechanical and thermal properties of the composites were studied and compared to pure PP composite. It is observed from the results that the composite with 50 weight % of silk fiber loading has shown greater mechanical properties. Furthermore, the incorporation of silk fibers in the polypropylene matrix has shown an improvement in the mechanical properties of 71.6 %, 76.66 %, 69.73 %, 67.97 %, and 58.45 % for tensile strength, tensile modulus, flexural strength, flexural modulus, and impact strength, respectively, in the composites when compared to pure polypropylene composite. The Differential Scanning Calorimetry analysis has also shown an increase in the degradation temperature of 8°C in the silk fiber-reinforced composite.

Authors: Kalusuraman G. , Thirumalai Kumaran S. , Siva I. , Anand Kumar S.
Published: December 2018

The work addresses the cutting performance of luffa cylindrica fiber–reinforced composite by abrasive water jet machining (AWJM). The composite (30, 40, and 50 wt. % fiber) is prepared using the compression molding technique. The extracted fiber morphology and the composite properties were analyzed, as per ASTM. The influence of machining parameters, such as jet pressure (P), traverse speed (TS), and standoff distance (SoD) over the taper angle (TA) and surface roughness (Ra), were analyzed. Based on the experimental results, it was observed that a higher value of P and lower TS and SoD resulted with minimum TA and Ra. The developed multilinear regression model confirms the goodness-of-fit at 95 % confidence interval. The optimum condition to set (P at 25 MPa, SoD at 1.1414 mm, and TS at 20 mm/min) for attaining minimum TA and Ra were determined by desirability analysis. Further, the analysis of variance (ANOVA) of TA depicted a contribution of 41.71 % by SoD, followed by TS and P by 27.33 % and 23.74 %, respectively. Similarly, the ANOVA of Ra resulted with a contribution of 16.72 % by P, 39.15 % by SoD, and 30.73 % by TS. Finally, the cut surface morphology of the composite was analyzed at optimum condition, and the results are revealed.

405 nm and 450 nm photoinactivation of Saccharomyces cerevisiae
Authors: Hoenes K. , Hess M. , Vatter P. , Spellerberg B. , Hessling M.
Published: December 2018

Photoinactivation of bacteria with visible light has been reported in numerous studies. Radiation around 405 nm is absorbed by endogenous porphyrins and generates reactive oxygen species that destroy bacteria from within. Blue light in the spectral range of 450–470 nm also exhibits an antibacterial effect, but it is weaker than 405 nm radiation, and the photosensitizers involved have not been clarified yet, even though flavins and porphyrins are possible candidates.

There are significantly fewer photoinactivation studies on fungi. To test if visible light can inactivate fungi and to elucidate the mechanisms involved, the model organism Saccharomyces cerevisiae (DSM no. 70449) was irradiated with violet (405 nm) and blue (450 nm) light. The mean irradiation doses required for a one log reduction of colony forming units for this strain were 182 J/cm2 and 526 J/cm2 for 405 nm and 450 nm irradiation, respectively.

To investigate the cell damaging mechanisms, trypan blue staining was performed. However, even strongly irradiated cultures hardly showed any stained S. cerevisiae cells, indicating an intact cell membrane and thus arguing against the previously suspected mechanism of cell membrane damage during photoinactivation with visible light at least for the investigated strain. The results are compatible with photoinactivated Saccharomyces cerevisiae cells being in a viable but nonculturable state.

To identify potential fungal photosensitizers, the absorption and fluorescence of Saccharomyces cerevisiae cell lysates were determined. The spectral absorption and fluorescence results are in favor of protoporphyrin IX as the most important photosensitizer at 405 nm radiation. For 450 nm irradiation, riboflavin and other flavins may be the main photosensitizer candidates, since porphyrins do not play a prominent role at this wavelength. No evidence of the involvement of other photosensitizers was found in the spectral data of this strain.

Published: December 2018

ABSTRACT Background: Chronic kidney disease affects more than 500 million people worldwide. In this context, the uremic toxins present are related to worsening in tissue healing. Aim: Evaluate on healing of colonic anastomosis in uremic rats, serum and anatomopathological indicators, which may be related to the change tissue repair process. Methods: Twenty Wistar rats, were randomly separated into two groups. In the sham group they were submitted to 5/6 nephrectomy simulation in left kidney, simulation right nephrectomy, median laparotomy, colotomy and colorraphy. In the uremia group, they were submitted to 5/6 nephrectomy of the left kidney, total nephrectomy of the right kidney and median laparotomy, colotomy and colorraphy. Were collected for serum urea, creatinine and CRP dosages and the colonic segments were studied for evaluation of granulation tissue, collagen maturation, microvascular and myofibroblasts density, and cell viability. Through histochemical processing, microvascular density was evaluated by anti-CD34 monoclonal antibody marking, cell viability by cell proliferation nuclear antigen screening and myofibroblasts density with monoclonal anti-α-actin antibody. Computerized histometry was used for evaluations of collagens type I and III by the coloration of picrosirius. Results: The group submitted to nephrectomy 5/6, compared to the sham group, show urea increase (p<0.0000) and higher C reactive protein (p=0.0142). Decrease of granulation tissue formation (border reepithelialization p=0,0196, angiofibroblast proliferation p=0.0379), mean collagen I (p=0,0009) and collagen III (p=0,016), microvascular density (p=0,0074), cell proliferation nuclear antigen (p<0,0000) and myofibroblasts (p<0,0001). Conclusion: The uremia induced by nephrectomy 5/6 model establishes negative impact in the colonic wound healing.

Published: December 2018

ABSTRACT Background: Gastric cancer is the 3rd most common cause of death in men and the 5th common in women worldwide. Today, surgery is the only curative therapy. Currently available advanced imaging modalities can predict R0 resection in most patients, but it can only be detected with certainty in the perioperative period. Aim: To determine the role of serum CK18, MMP9, TIMP1 levels in predicting R0 resection in patients with gastric cancer. Methods: Fifty consecutive patients scheduled for curative surgery with gastric adenocarcinoma diagnosed between 2013-2015 were included. One ml of blood was taken from the patients to analyze CK18, MMP9 and TIMP1. Results: CK18, MMP9 and TIMP1 levels were positively correlated with pathological N and the stage (p<0,05). CK-18, MMP-9 and TIMP-1 averages in positive clinical lymph nodes and in clinical stage 3, were found to be higher than the averages of those with negative clinical lymph nodes and in clinical stage 2 (p<0,05). Conclusion: Although serum CK-18, MMP-9 and TIMP-1 preoperatively measured in patients scheduled for curative surgery did not help to evaluate gastric tumor resectability, they were usefull in predicting N3-stage.

Resumo O “Oral Impacts on Daily Performances (OIDP)” é um indicador de qualidade de vida relacionada com a saúde oral. Foi desenvolvido com o intuito de avaliar o impacto das condições orais na capacidade de o indivíduo desempenhar atividades diárias. O principal objetivo deste trabalho foi validar o OIDP para a população Portuguesa, com idade igual ou superior a 18 anos. Começou-se por obter uma versão portuguesa provisória: traduziu-se o original inglês e retro traduziu-se. Fizeram-se adaptações linguísticas e obteve-se a versão portuguesa do OIDP (OIDP-PT), aprovada por uma comissão de revisão composta por investigadores e tradutores. Fez-se o estudo piloto, com 36 participantes (26 em papel e 10 “online”). Por fim, realizou-se o estudo final com 513 participantes, tendo a recolha de dados sido feita “online”. Ao nível da confiabilidade, determinou-se o alfa de Cronbach (0,67) e o alfa com base em itens padronizados (0,69). A validade foi estudada nas suas várias vertentes: validade de face, de conteúdo, de construto e concorrente. O OIDP-PT mostrou ter boas propriedades psicométricas e ser um instrumento confiável e válido para ser aplicado à população portuguesa.
A influência de um sangradouro na distribuição espaço-temporal do isópode Tholozodium rhombofrontalis (Isopoda, Sphaeromatidae)
Authors: Pinto Larissa R. , Borzone Carlos A.
Published: December 2018

RESUMO As descargas de água doce permanentes em praias arenosas, conhecidas como sangradouros, promovem alterações em diferentes escalas espaciais e temporais sobre as características ambientais, e consequentemente sobre as populações macrobentônicas. O objetivo deste estudo foi avaliar as alterações da abundância, distribuição e estrutura populacional do isópode Tholozodium rhombofrontalis (Giambiagi, 1922) em um sangradouro permanente. Coletas sazonais foram realizadas na praia de Barrancos, cidade de Pontal do Paraná, estado do Paraná, sul do Brasil, em três locais: sangradouro (dentro do sangradouro), intermediário (a 30 m de distância do sangradouro) e distante (a 150 m de distância do sangradouro), durante as quatro estações dos anos de 2012 e 2013. A praia foi morfodinamicamente caracterizada como intermediária, composta de sedimentos finos e bem selecionados. No local sangradouro os perfis topográficos foram suaves e extensos, e o lençol freático raso e doce. Em contrapartida, no local distante os perfis foram íngremes e curtos, e o lençol freático profundo e salino. O local intermediário apresentou características similares ao do sangradouro. Houve uma variabilidade espacial e temporal na abundância e distribuição do isópode, estando as maiores abundâncias nos locais sangradouro e intermediário, com picos nas estações primavera e verão. Tais variações foram relacionadas à presença de águas salobras e altos valores de clorofila a. A proporção de juvenis foi a maior dentre todas as classes, e manteve-se regular temporalmente, indicando um recrutamento contínuo. As proporções de fêmeas mantiveram-se similares temporalmente confirmando a estabilidade da população. A proporção de machos foi baixa em todos os locais e durante todas as coletas, contudo, a baixa representatividade desta classe não afetou negativamente o estabelecimento da população. As fêmeas ovígeras estiveram presentes em todos os locais e em todas as coletas, com as maiores proporções no inverno, apontando uma possível preferência por uma estação mais fria para a reprodução. A presença de um sangradouro permanente proporcionou a esta praia condições de salinidade estuarina, o que possivelmente favoreceu o estabelecimento da população.
THE MEANING OF WORK AS A PREDICTOR OF THE INTENTION TO REMAIN/LEAVE AMONG TEACHERS
Authors: HELENO CAMILA T. , BORGES LIVIA O. , AGULLÓ-TOMÁS ESTEBAN
Published: December 2018

ABSTRACT Purpose: Assessing whether the meanings attributed to the work by teachers from a course of professional technological education (PTE), Human Resource Management (HRM) were predictors of the intention to remain in or to leave employment. Originality/value: There is a gap in the literature about the research of the relationship between working meanings and the turnover intention. Also, the recent expansion of PTE in Brazil was not accompanied by the development of research related to different aspects of the work of the teachers who work in PTE, considering that they act in a context of the historical and cultural devaluation of HRM teachers Design/methodology/approach: We developed a multi-methodological study in two stages: 1. Application of semi-structured interviews; 2. Application of structured questionnaires. Findings: The results of the first stage provided an empirical basis for constructing hypotheses concerning the prevalence of leaving intention and the prediction of this phenomenon by the components of work meaning. The results of the second stage confirmed that the leaving intention was prevalent among most HRM teachers. Also, a valuation of the dignity-humanization, the occupation and a sense of the reality of dehumanization and exhaustion are predictors of the likelihood of the leaving intention. We concluded that, despite the increased job opportunities for teachers in PTE, it does not represent a quality alternative, as well as HRM teachers, considered it a temporary option of work.
E se soubéssemos mais? Simulando os votos e as opiniões dos eleitores mais informados no Brasil
Authors: Freire Alessandro , Masson Pedro , Turgeon Mathieu
Published: December 2018

RESUMO Introdução Décadas de pesquisas sobre a opinião pública demonstraram que a maioria das pessoas é altamente desinformada a respeito da política. Entretanto, as consequências dessa desinformação sobre o comportamento eleitoral e sobre as atitudes dos cidadãos ainda parecem pouco claras, especialmente quando se trata de jovens democracias. Métodos Neste artigo, utilizamos simulações estatísticas de um eleitorado “completamente informado” a partir de dados do Estudo Eleitoral Brasileiro (ESEB) para responder às seguintes perguntas: (1) Como os brasileiros votariam caso fossem mais informados? (2) Como seriam as opiniões políticas dos brasileiros caso fossem mais informados? Aqui, "informação" se refere a conhecimento sobre a política e o governo de maneira geral Resultados Os resultados sugerem que os votos e as opiniões políticas dos brasileiros seriam diferentes caso eles fossem mais informados. A falta de informação parece direcionar sistematicamente as preferências coletivas, sugerindo que tais erros não são aleatórios, mas sim produto de assimetrias de informação entre os cidadãos Discussão Essas assimetrias podem ser especialmente problemáticas quando se trata de quais opiniões são levadas em consideração pelos representantes dos eleitores, ao tomarem decisões importantes. Os efeitos da desinformação política têm sido vistos sob diferentes olhares pela Ciência Política. Embora alguns teóricos argumentem que a falta de informação não tem efeitos significativos sobre a democracia, outros creem que ela pode trazer consequências notáveis para as escolhas coletivas e para as atitudes políticas dos cidadãos. Nossos resultados nos colocam ao lado do segundo grupo de pesquisadores.
Management proposal based on the timing of oral incubation of eggs and juveniles in the sentinel species Genidens genidens (Siluriformes: Ariidae) in a tropical estuary
Authors: Maciel Thaís Rodrigues , Vaz-dos-Santos André Martins , Caramaschi Erica Pellegrini , Vianna Marcelo
Published: December 2018

ABSTRACT Ariids such as Genidens genidens are particularly susceptible to overfishing because of their complex reproductive mechanisms, which result in slow replenishment of stocks. In this study, we obtained data about the reproductive ecology of the catfish G. genidens in the Guanabara Bay estuary, Rio de Janeiro, Brazil, providing supporting information for management of its fishery. The sex ratio, mean size of each sex at first sexual maturation, and female fecundity were determined and the reproductive period was characterized. The males:females ratio was 1:2. The fecundity is low and increases proportionally to the females’ growth in total length and weight. The breeding season occurs during the warmest months of the year, with spawning extending from October through March and incubation from December through April. Sexual maturation is late, with males maturing at a larger size than females. Skipping spawning was also identified in females. Based on the reproductive biology, it is suggested that the catch be restricted to individuals larger than 20 cm, considering the L75 of the males, and that fishing be prohibited from December through March, to include the main period of spawning season by females and oropharyngeal incubation by males.
Reflexiones en torno a las metástasis de las desigualdades en las estructuras educativas latinoamericanas
Authors: Kaztman Ruben
Published: December 2018

Resumen En las grandes ciudades de América Latina los avances de la mercantilización en el acceso a servicios básicos y en las operaciones inmobiliarias que distribuyen la población en distintas zonas de residencia producen grietas profundas en el tejido social. Pese a la gravedad del impacto de estos fenómenos en el tono de la convivencia urbana, hay un déficit de reflexiones al rededor a los mecanismos que conectan las desigualdades económicas con las segmentaciones y segregaciones en los servicios y en los lugares de residencia. El presente ensayo aporta a la reducción de esas carencias discutiendo los mecanismos macro y micro sociales que intervienen en la relación entre desigualdades económicas y desigualdades educativas. Como conclusión sugiere algunas prioridades para una agenda académica regional orientada a mejorar nuestro conocimiento de esas relaciones.
Ammonium thiosulfate as blossom thinner in 'Maxi Gala' apple trees
Authors: Marchioretto Lucas De Ross , Rossi Andrea De , Michelon Micheli Fochesato , Orlandi Julio Cesar , Amaral Leonardo Oliboni do
Published: December 2018

Abstract: The objective of this work was to evaluate the feasibility of using ammonium thiosulfate as a chemical blossom thinner in 'Maxi Gala' apple (Malus domestica) trees and its effects on fruit quality. The experiment was carried out in an experimental orchard in the Southern Brazil, in a randomized complete block design, with five replicates. Ammonium thiosulfate was sprayed on the apple trees at the full bloom stage, at 0, 1.5, 2.5, and 3.5%. Evaluations were performed for the effects on crop load, fruit set, yield efficiency, and fruit quality parameters such as weight, shape, total soluble solids, seed number, flesh firmness, color, and russeting occurrence. Ammonium thiosulfate at 2.5% is effective to reduce crop load and to improve fruit quality. The thinning effect of ammonium thiosulfate is not dependent on the weather conditions during the crop season. The rate of 3.5% of ammonium thiosulfate causes overthinning and does not result in the improvement of fruit quality.

Published: December 2018

Abstract: The objective of this work was to obtain cowpea (Vigna unguiculata) progenies with compound inflorescences, short peduncles, early cycle, good plant architecture, and high-yielding potential. The initial genetic material consisted of 453 F2:3 progenies, selected from ten crosses and evaluated using Federer’s augmented block design, with two controls. Of these, 60 progenies from the F4:5 and F4:6 generations were selected and assessed in two consecutive experiments, both in a 8x8 lattice design with four controls and four replicates. Early selection was efficient at fixing the evaluated traits. A wide genetic variability was detected among and within progenies. The estimated and obtained heritability and genetic gains in the F4:5 and F4:6 progenies indicate the possibility of selection of early progenies with short peduncles, compound inflorescences, and productivity similar to or greater than that of the commercial cultivars used as controls.
Desempenho de ureia revestida compoliuretano como fertilizante de Phaseolus vulgaris L.
Authors: Silva Edilaine Ferreira da , Escanio Camila Alves , Oliveira Magno André de , Bezerra Augusto Cesar da Silva , Machado Alan Rodrigues Teixeira
Published: December 2018

RESUMO Devido a sua grande importância mundial, a cultura do feijoeiro requer uma produção em grande escala, tornando necessária a utilização de fertilizantes. Dentre eles, a ureia se destaca como um dos mais importantes. No entanto, observam-se perdas significativas do nitrogênio por meio de lixiviação, volatilização e desnitrificação. Para contornar esse problema, vários grupos de pesquisa têm estudado o revestimento de fertilizantes com polímeros, uma vez que, por meio deles, é possível controlar a liberação de nutrientes, bem como a sua disponibilidade no solo. Nesse contexto, o presente trabalho revestiu grânulos de ureia por meio de uma mistura simples de difenilmetano diisocianato e poliol poliéter. Foram produzidos cinco tipos de revestimentos variando as proporções dos reagentes. Todas as amostras foram caracterizadas por espectroscopia de infravermelho e microscopia eletrônica de varredura e foram realizados ensaios in vivo com Phaseolus vulgaris L.. Os espectros de infravermelho confirmaram a polimerização por meio da formação da ligação de uretana. As micrografias evidenciaram um recobrimento com espessura inferior a 30 µm. Os ensaios de liberação controlada da ureia em água mostraram que os revestimentos poliméricos retardam a liberação da ureia em aproximadamente 50 % durante um período de 200 min. Já os ensaios in vivo mostraram que a utilização da ureia com revestimentos nas proporções (em massa) de 60:40 e 50:50 (difenilmetano diisocianato/poliol poliéter) elevaram o teor de massa seca em 52 e 22 %, respectivamente. Com isso, conclui-se que é possível revestir fertilizantes nitrogenados de forma simples com eficiência, otimizando a liberação dos nutrientes no solo e tornando-os mais sustentáveis.

SUMMARY This study aimed to evaluate the bio-economic performance in confinement crossbred goats from different genetic groups. Were used 30 goats, crossbred (F1) intact male, 10 goats Boer x SPRD (undefined breed), 10 x Savannah SPRD and 10 Oberhasli x SPRD, with an average weight of 15 kg and an average age of 100 days. The initial weight was evaluated, final body weight, average daily gain, total weight gain, dry matter intake, water intake, feed conversion and days on feed. As an economic indicator was calculated gross profit margin (MB), the average dry matter intake, the confinement period, the cost of each diet and the cost of vaccines and medicines. We used the 5% Tukey test for comparisons between treatment means. For the variables weight gain, dry matter intake, water intake and body condition score averages observed did not differ between the genetic groups. There was significant effect (P> 0.05) of genetic groups on days on feed. The biological performance of the goats finished in feedlot was not influenced by genetic group. In bioeconomic analysis was no significant difference (P> 0.05) between the evaluated racial groups. Gross profit margin was negative for the mestizos Pardo Alpine x SPRD. The cross between the Boer breed and without defined breed results in premature animals, reaching slaughter weights with reduced confinement period. In the feedlot finishing system crossbred Boer goats x SPRD showed better economic performance, providing greater profitability to the creator.
Barriers to Higher Education for Students with Bipolar Disorder: A Critical Social Model Perspective
Authors: Kruse Allison K. , Oswal Sushil K.
Published: December 2018

Employing some of the features of participatory research methodology, a disabled faculty joins a student with mental health diagnosis to examine the factors that hinder or enable success for this group. The theoretical framework or scholarly bearings for the study comes from the critical social model of disability, disability services scholarship in the United States, and education theory literature on “student success”. With a particular focus on students with bipolar disorder, the article highlights the gaps in disability scholarship on this specific group while underscoring the oppression experienced by them through the inclusion of an autoethnographic segment by the primary author in this collaborative, scholarly work. The model of access, we propose, moves beyond accommodations—which are often retrofits or after the thought arrangements made by an institution—and asks for environmental support, social and institutional inclusion, and consideration for students with psychiatric health diagnosis. This article not only presents an array of problems in the United States academy but also a set of recommendations for solving these problems. Going beyond the regime of retrofit accommodations, we ask for an overhaul of institutional policies, infrastructures, and curricula so that the academy is inclusive of neurodiverse bodies and appreciates their difference.

La teoría Funcional de la Lexicografía y sus consecuencias para los diccionarios de economía del español
Authors: Fuertes-Olivera Pedro A. , Tarp Sven
Published: December 2018

Con este artículo ofrecemos una visión de la lexicografía desde la perspectiva de la teoría funcional, que defiende que la lexicografía es la teoría y práctica de las herramientas de uso que facilitan un acceso rápido al tipo específico de datos de los cuales un tipo específico de usuarios puede extraer el tipo específico de información que le permita satisfacer el tipo específico de necesidades lexicográficamente relevantes que tenga en un tipo específico de situación social extralexicográfica. La aplicación de la teoría al estudio de los diccionarios cognitivos y comunicativos del campo de la economía nos ha permitido observar que la mayoría de estos diccionarios no son adecuados, fundamentalmente porque se han confeccionado o bien sin criterio lexicográfico alguno, o bien con un criterio parcial. Quizás sea nuestro objetivo final que los estudiosos de la lengua encuentren en los fundamentos de esta teoría la base teórica y los instrumentos prácticos con los que mejorar el mercado de productos lexicográficos existentes en el mundo de habla hispana, algo muy importante para el desarrollo de la sociedad de la información y el conocimiento.

Published: December 2018

Neste artigo, temos como objetivo analisar as narrativas docentes a partir do que interpretamos como uso pedagógico da realidade na Educação Matemática. Os excertos selecionados de um congresso do campo referido foram organizados segundo suas semelhanças possibilitando a constituição de identidades docentes que representam, controlam, regulam o uso pedagógico da realidade. Nosso viés teórico é pautado nos estudos de Michel Foucault a partir da perspectiva pós-estrutural. Assim, atentos a essas representações, as produções da rede discursiva em Educação Matemática, buscamos tensionar como os discursos em torno da docência constituem um saber específico sobre a docência contemporânea. Não apenas constituem, mas são constituídos do que denominamos saber-realidade. Tal maneira de produzir a docência segue compondo os entendimentos; segue regulando e orientando as práticas pedagógicas em prol de uma matemática contextualizada, utilitarista, lúdica, significativa. Enfim, uma matemática que esteja em todos os lugares, que pertença a todos.
Reflexiones sobre la naturaleza jurídica del derecho de autor
Authors: Anaya-Quintero Laura , Cruz-Fino Jessica
Published: December 2018

Las discusiones sobre la naturaleza jurídica del derecho de autor se remontan al siglo xix. Para resolver tal cuestionamiento, desde esa época, se han propuesto varias teorías. Estas han oscilado entre dos extremos, por un lado, considerar el derecho de autor como un derecho de la personalidad y, por otro, entenderlo como un derecho de propiedad. A pesar de todos los estudios que se han llevado a cabo, aún no parece haber claridad suficiente sobre el asunto. Este artículo analiza las principales teorías con el objetivo de precisar cuál de ellas se acerca más a la verdadera naturaleza jurídica del derecho de autor. Pretende, además, estudiar las implicaciones de la elevación a rango constitucional fundamental de los derechos morales en Colombia. Todo lo anterior, más allá de querer seguir teorizando sobre la materia, busca poner en evidencia las consecuencias de asumir una u otra postura al respecto.

Objectives:
The
treatment of arterial hypertension requires a comprehensive care because it is
necessary not only to take the prescribed medication but also to apply certain
rules of hygiene. The purpose of this study was to evaluate the effect of a
program of physical activity adapted to the morphological and physiological
state of the hypertensive patients.

Methods: An experimental study was
conducted on a sample of 31 male hypertensive patients with an average age of
58.16 ± 3.7 years undergoing an aerobic and anaerobic physical activity program
treadmill walking, cycling, ergonomics and aerobic exercise and muscle building
exercises of moderate intensity, duration of forty-five minutes and a frequency
of three times a week associated with low calorie nutrition education low in
cholesterol and saturated fatty acids (bad fats) , low sodium rich in
vegetables, fruits and vitamins for 4 months at the University Clinics of
Kinshasa between January 2017and May 2017.

Results: After 4 months of
intervention, we found statistically significant reductions in weight -7.2 kg,
waist circumference -7.61 cm, body mass index -5.42 kg/m2, visceral
fat percentage -1.4%, systolic blood pressure -6 mmHg, low-density lipoprotein
-22 mg/dL, triglyceride -26.7 mg/dL with the exception of high-density
lipoprotein and muscle that statistically increased +7.42 mg/dL and +15.3%
while diastolic blood pressure -3.4 mmHg was not statistically modified.

Conclusion: The practice of adapted physical activities combined with
nutritional education improves the morphological and physiological status of
hypertensive patients.
Luiz Gama e Leandro Gomes de Barros em Perspectiva Dialógica

Published: December 2018

Neste artigo pretendemos investigar as possíveis relações dialógicas intertextuais que os poemas satíricos de Luiz Gama (1830-1882) e Leandro Gomes de Barros (1865-1918) estabelecem entre si bem como com a tradição oral e escrita da sátira, na qual os textos de ambos se inscrevem. Devem ser levadas também em consideração as relações dialógicas polifônicas – ou embates de vozes – que os textos destes poetas estabelecem com os discursos instituidores de “verdades” sobre as sociedades das quais fazem parte. Neste segundo tópico pretendemos investigar, em alguns poemas selecionados, como cada poeta respondeu às demandas de seu tempo, sobretudo políticas e sociais, que lhes foram apresentadas.Palavras-Chave: Leandro Gomes de Barros.

Published: December 2018

Sesame is notable for its rich antioxidants and sesame oil is also familiar for its resistance to oxidation. The cultivation of sesame is usually restricted under abiotic stress conditions. Hence in order to study the performance of sesame genotypes to saline stress, an experiment was conducted to screen ten ruling varieties of sesame viz., CO1, SVR1, SVPR1, VRI 1, VRI 2, TMV 3, TMV 4, TMV 5, TMV 6 and TMV 7 at five different EC levels (EC 1, 2, 3, 4 and 5). Seedling observations namely, germination percentage, speed of germination, shoot length, root length and dry matter production were recorded. Among the genotypes, it was found that under higher saline conditions (EC5), VRI 1 recorded higher seedling length (2.0 cm), vigour index I (100) and vigour index II (1.15), whereas under normal condition, TMV 4 and CO 1 performed better. In general, there was a decrease in all the seedling parameters with increased levels of salinity. With STAR software, Multivariate analysis was done and on the basis of dendrogram, five clusters were formed and the cophenotic correlation co- efficient was found highest in Control (0.912) followed by EC 2 ( 0.829).
Avaliação da exposição ocupacional à vibração de motosserra: um estudo sobre a colheita florestal no Espírito Santo
Authors: Bermudes Wanderson Lyrio , Minette Luciano José
Published: December 2018

As atividades florestais contabilizaram, no período de 2007 a 2012, no Brasil, em média, uma incidência de 30 acidentes para cada grupo de 1.000. Esta pesquisa tem como o objetivo principal demonstrar a intensidade do agente físico “vibração localizada”, originado da utilização de motosserra nas atividades de colheita florestal em área de fomento no Espírito Santo. As avaliações foram realizadas conforme preconiza a Norma de Higiene Ocupacional NHO 10 da Fundação Jorge Duprat e Figueiredo (Fundacentro), e seus resultados comparados com as Normas Regulamentadoras NR-09 e NR-15 Anexo 8, que estabelecem os limites máximos permitidos para uma exposição diária de oito horas. A exposição média de vibração foi, para acionamento, de 2,8 m.s-2 e de 4,4 m.s-2 para empunhadura.  A aceleração de maior intensidade para uma jornada de oito horas foi de 6,87 m.s-2, superior ao limite de tolerância de 5,0 m.s-2. Sugere-se nesta pesquisa a adoção de medidas de controle para a redução do risco de vibração, haja vista que a intensidade média ultrapassou o nível de ação.

Background: Incident reporting systems are designed to obtain information about patient safety and used for organizational and individual learning.Aims: The objective is to evaluate the implementation of patient safety incident reporting system at a hospital of Surabaya.Method: This study was an observational descriptive research supported by qualitative data. This study used Health Metrics Network (HMN) model.Results: The results of the input evaluation show that there was a policy that regulates the incident report, but its implementation was still not appropriate with no direct funding. However, facilities were provided for reporting. There were socialization for employees who have different understanding and responsibility, organizational structure of the patient safety team, problem solving method which had not used PDSA (Plan, Do, Study, Action), and computerized technology.Conclusion: The process evaluation shows that the indicators were in line with the rules. The data sources were in accordance with the guidelines. Data collection, process, presentation, and analysis were in line with the theory. The output evaluation shows the submission of incident reports had not been timely. Moreover, the report was complete and suitable to the existing guidelines, and it had been used for decision-making. It is required for the hospital to revise the guidebook of incidence reporting and improve the human resource skill.Keywords: evaluation, incident, patient safety, reporting
Messianismo e poder temporal: Messianismo e poder temporal a partir de SlSal 17 e de Mc 12,13-17
Authors: UTRINI Heitor Carlos Santos
Published: December 2018

O título “Cristo” é um dos mais importantes no evangelho de Marcos para se compreender a identidade de Jesus. Apesar de o conceito ser usado no AT e na literatura judaica intertestamentária, o evangelho é um esforço de ressignificar completamente o conceito aplicando-o à novidade da pessoa de Jesus. O presente artigo é um estudo sobre essa relevante temática e se desenvolverá em dois momentos: primeiramente, o conceito de Messias será analisado a partir das antigas tradições judaicas tendo como ponto de partida o Salmo de Salomão 17. Num segundo momento será analisado o texto de Mc 12,13-17 acerca do pagamento do tributo a César. O diálogo entre os textos permitirá descobrir os pontos de contato e as diferenças mais significativas entre os ideais messiânicos presentes nas passagens.
El automanejo de las enfermedades crónicas: un método integral de atención
Authors: Grady Patricia A. , Gough Lisa Lucio
Published: December 2018

Tanto por razones clínicas como económicas, cada vez son más las personas que llevan adelante su vida con alguna enfermedad crónica, lo que representa una cuestión de salud pública cuya importancia está en aumento. Al hacer hincapié en la responsabilidad del paciente y la importancia de actuar conjuntamente con la comunidad de prestadores de servicios de salud, el automanejo representa una estrategia prometedora de atención de las enfermedades crónicas que permite ir más allá de la información para enseñar activamente a las personas a detectar y resolver los problemas asociados con la enfermedad que tienen. El automanejo también resulta prometedor como un paradigma eficaz en el espectro de la prevención (primaria, secundaria y terciaria) porque establece un modelo de salud en la niñez y proporciona estrategias para mitigar la enfermedad y manejarla en las etapas posteriores de la vida. Proponemos diversas maneras de mejorar los métodos de investigación y las aplicaciones prácticas del automanejo, que a la vez pueden ser pasos en su desarrollo y ejecución futura.
Mejorar el acceso mundial a las nuevas vacunas: propiedad intelectual, transferencia de tecnología y vías de reglamentación
Authors: Crager Sara Eve
Published: December 2018

En el Plan de acción mundial sobre vacunas, aprobado por la Asamblea Mundial de la Salud en el 2012, se hizo un llamamiento en pro del acceso mundial a las nuevas vacunas en un plazo de 5 años desde que se otorga la licencia. Sin embargo, los métodos actuales han resultado insuficientes para lograr fijar precios sostenibles para las vacunas en dicho plazo. En paralelo con la estrategia exitosa de la competencia de los genéricos para reducir el precio de los medicamentos, está surgiendo un consenso claro sobre el hecho de que la entrada en el mercado de múltiples proveedores es un factor fundamental para reducir rápidamente el precio de las nuevas vacunas. En este contexto, los principales objetivos para mejorar el acceso a las nuevas vacunas incluyen superar los obstáculos de la propiedad intelectual, simplificar las vías de reglamentación de las vacunas biosimilares y reducir los plazos de entrada en el mercado de los fabricantes de vacunas de los países en desarrollo mediante la transferencia de tecnología y conocimientos prácticos. En este artículo propongo crear un banco de propiedad intelectual, tecnología y conocimientos prácticos como un nuevo enfoque a fin de facilitar el acceso generalizado a las nuevas vacunas en los países de ingresos medianos y bajos mediante la transferencia eficaz de las técnicas de producción de vacunas patentadas a múltiples fabricantes de vacunas en los países en desarrollo.
