Shelley’s Unknown Eros: Post-Secular Love in Epipsychidion
Authors: Tomko Michael
Published: September 2016

Whether Percy Bysshe Shelley’s Epipsychidion—a Platonic poem on love addressed to the patriarchally imprisoned Theresa Viviani or “Emily”—receives praise or blame has generally been determined by two focal passages: a secular sermon on free love and a planetary allegorical thinly veiling his own imbroglio. This essay re-reads Shelley’s 1821 work drawing on two recent arguments: Stuart Curran’s Dantean call to take the poem’s Florentine narrator seriously as a character, not just as an autobiographical cypher, and Colin Jager’s outline of Shelley’s move beyond the assumptions of his professed atheism after 1816. Based on the poem’s structure and imagery, the paper argues that Epipsychidion critiques the false sense of revolutionary ascent and dualistic escape offered to Emily, who is commodified and erased by the narrator’s egocentric, “counterfeit divinization of eros” (Benedict XVI). Turning from this Radical Enlightenment Platonism, the poem momentarily realizes an embodied, hylomorphic romantic union akin to the Christian nuptial mystery of two becoming “one flesh” (Mark 10:8). This ideal, however, collapses back into solipsism when the narrator cannot understand or accept love as a “unity in duality” (Benedict XVI). This paper thus claims Epipsychidion as a post-secular inquiry into the problem of love whose philosophic limits and theological horizons are both surprising and instructive. It also reclaims Shelley as a phenomenological poet who can open up the world to Christian and non-Christian readers, one whose Platonic and Dantean formation lend him an openness to transcendence and one whose countercultural path through life makes him wary of inhumane appropriations of religion.
Ambient Sound-Based Collaborative Localization of Indeterministic Devices
Authors: Kamminga Jacob , Le Duc , Havinga Paul
Published: September 2016

Localization is essential in wireless sensor networks. To our knowledge, no prior work has utilized low-cost devices for collaborative localization based on only ambient sound, without the support of local infrastructure. The reason may be the fact that most low-cost devices are indeterministic and suffer from uncertain input latencies. This uncertainty makes accurate localization challenging. Therefore, we present a collaborative localization algorithm (Cooperative Localization on Android with ambient Sound Sources (CLASS)) that simultaneously localizes the position of indeterministic devices and ambient sound sources without local infrastructure. The CLASS algorithm deals with the uncertainty by splitting the devices into subsets so that outliers can be removed from the time difference of arrival values and localization results. Since Android is indeterministic, we select Android devices to evaluate our approach. The algorithm is evaluated with an outdoor experiment and achieves a mean Root Mean Square Error (RMSE) of 2.18 m with a standard deviation of 0.22 m. Estimated directions towards the sound sources have a mean RMSE of 17.5 ° and a standard deviation of 2.3 °. These results show that it is feasible to simultaneously achieve a relative positioning of both devices and sound sources with sufficient accuracy, even when using non-deterministic devices and platforms, such as Android.
A Microchip for Integrated Single-Cell Gene Expression Profiling and Genotoxicity Detection
Authors: Dong Hui , Sun Hao
Published: September 2016

Microfluidics-based single-cell study is an emerging approach in personalized treatment or precision medicine studies. Single-cell gene expression holds a potential to provide treatment selections with maximized efficacy to help cancer patients based on a genetic understanding of their disease. This work presents a multi-layer microchip for single-cell multiplexed gene expression profiling and genotoxicity detection. Treated by three drug reagents (i.e., methyl methanesulfonate, docetaxel and colchicine) with varied concentrations and time lengths, individual human cancer cells (MDA-MB-231) are lysed on-chip, and the released mRNA templates are captured and reversely transcribed into single strand DNA. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), cyclin-dependent kinase inhibitor 1A (CDKN1A), and aurora kinase A (AURKA) genes from single cells are amplified and real-time quantified through multiplex polymerase chain reaction. The microchip is capable of integrating all steps of single-cell multiplexed gene expression profiling, and providing precision detection of drug induced genotoxic stress. Throughput has been set to be 18, and can be further increased following the same approach. Numerical simulation of on-chip single cell trapping and heat transfer has been employed to evaluate the chip design and operation.

Authors: Reis Joel , Morgado Marco , Batista Pedro , Oliveira Paulo , Silvestre Carlos
Published: September 2016

This paper presents the steps for developing a low-cost POrtableNavigation Tool for Underwater Scenarios (PONTUS) to be used as a localization device for subsea targets. PONTUS consists of an integrated ultra-short baseline acoustic positioning system aided by an inertial navigation system. Built on a practical design, it can be mounted on an underwater robotic vehicle or be operated by a scuba diver. It also features a graphical user interface that provides information on the tracking of the designated target, in addition to some details on the physical properties inside PONTUS. A full disclosure of the architecture of the tool is first presented, followed by thorough technical descriptions of the hardware components ensemble and the software development process. A series of experiments was carried out to validate the developed prototype, and the results are presented herein, which allow assessing its overall performance.
Multimodal Learning and Intelligent Prediction of Symptom Development in Individual Parkinson’s Patients

Published: September 2016

We still do not know how the brain and its computations are affected by nerve cell deaths and their compensatory learning processes, as these develop in neurodegenerative diseases (ND). Compensatory learning processes are ND symptoms usually observed at a point when the disease has already affected large parts of the brain. We can register symptoms of ND such as motor and/or mental disorders (dementias) and even provide symptomatic relief, though the structural effects of these are in most cases not yet understood. It is very important to obtain early diagnosis, which can provide several years in which we can monitor and partly compensate for the disease’s symptoms, with the help of various therapies. In the case of Parkinson’s disease (PD), in addition to classical neurological tests, measurements of eye movements are diagnostic. We have performed measurements of latency, amplitude, and duration in reflexive saccades (RS) of PD patients. We have compared the results of our measurement-based diagnoses with standard neurological ones. The purpose of our work was to classify how condition attributes predict the neurologist’s diagnosis. For n = 10 patients, the patient age and parameters based on RS gave a global accuracy in predictions of neurological symptoms in individual patients of about 80%. Further, by adding three attributes partly related to patient ‘well-being’ scores, our prediction accuracies increased to 90%. Our predictive algorithms use rough set theory, which we have compared with other classifiers such as Naïve Bayes, Decision Trees/Tables, and Random Forests (implemented in KNIME/WEKA). We have demonstrated that RS are powerful biomarkers for assessment of symptom progression in PD.
Dans cet entre-deux du présent et du passé : une écriture de l'histoire ?
Authors: Payen Pascal
Published: September 2016

The writing of history favoured by Nicole Loraux is set upon series of shifts and variations from otherwise familiar objects : "classical" Athenian democracy and ancient Greece's politics. Nicole Loraux introduces herself as historian of institutions, but of the institution of words, of funeral oration ; historian of myths, but taken in their civic founding ; historian not of women, but of the feminine and of the political differences between sexes, historian of the dividing as the most powerful bond in the city. Her forceful writing, which presents anachronism as a virtue to present Moderns' place in these constructions, is thus producing new objects, or ancient objects that a historian is asked to look at differently.
Nicole Loraux et le théâtre : sous le signe de Dionysos
Authors: Alaux Jean
Published: September 2016

L' étude insiste sur le rôle joué par le théâtre grec, surtout tragique, dans la réflexion de Nicole Loraux sur le politique : institution éminemment civique, le théâtre de Dionysos donne aussi à voir et à entendre ce que d'autres discours excluent, vouent au silence ou à l'oubli, et qui fait retour sur la scène ; si le mythe est mis à distance dans la représentation que s'en donne la cité, la cité elle-même est mise en question par le biais du mythe. Mais les études de Nicole Loraux, nourries par son activité de traductrice et sa collaboration avec les metteurs en scène d'aujourd'hui, conduisent également à méditer sur la nature propre du genre et sur les raisons de sa survie : on tâchera de souligner les constantes mais aussi les évolutions qui conduisent des premiers travaux aux pistes explorées dans La Voix endeuillée, centrées sur la dimension réflexive des œuvres et sur le caractère fondamentalement conflictuel du texte et du message tragiques.
De l'usage raisonné de l'anachronisme
Authors: Dosse François
Published: September 2016

Pendant longtemps la tradition historique française a chassé l'anachronisme comme une faute professionnelle au nom de la quête de vérité et du respect de l'authenticité. François Dosse montre tout l'intérêt de la transgression que réalise Nicole Loraux de cet interdit. Par là, elle prend toute la mesure des déplacements propres à une écriture de l'histoire considérée comme fondamentalement liée à un lieu et à un questionnement présent. Néanmoins, l'usage de l'anachronisme doit rester contrôlé pour éviter un certain nombre d'écueils mis ici en lumière.
Homère, une odyssée américaine
Authors: Bouvier David
Published: September 2016

In her first two books, L'invention d'Athènes and Les enfants d'Athéna, Nicole Loraux pays small attention to Homeric poetry. It is only at the beginnings of the eighties, that Homer will become a main point of Loraux' s researches, mainly in her inquiry on stasis as a political principle of the democratic city, or in her remarks on amnesty. Stimulated by the works of the American school on Homer, Nicole' Loraux not only helped to introduce them in France but developed, after them, a strong analysis of the subtle relationships between poetics and politics in Ancient Greece, a theory that will appear essential for the Homerists of everywhere.
Voix italiennes
Authors: Paradiso Annalisa
Published: September 2016

At first, Nicole Loraux's Italian ways lead us to Bari, then to Rome and Turin. Bari is the home of Laterza, her early-90s favorite publisher. Later she chose Meltemi, a Roman publisher, and finally Einaudi, in Turin. Loraux's Italian paths also drive us to Italian journals, to friends, to a large readership.

Objectives: To find discriminative combination of influential factors of Intracerebral hematoma (ICH) to cluster ICH patients with similar features to explore relationship among influential factors and 30-day mortality of ICH. Methods: The data of ICH patients are collected. We use a decision tree to find discriminative combination of the influential factors. We cluster ICH patients with similar features using Fuzzy C-means algorithm (FCM) to construct a support vector machine (SVM) for each cluster to build a multi-SVM classifier. Finally, we designate each testing data into its appropriate cluster and apply the corresponding SVM classifier of the cluster to explore the relationship among impact factors and 30-day mortality. Results: The two influential factors chosen to split the decision tree are Glasgow coma scale (GCS) score and Hematoma size. FCM algorithm finds three centroids, one for high danger group, one for middle danger group, and the other for low danger group. The proposed approach outperforms benchmark experiments without FCM algorithm to cluster training data. Conclusions: It is appropriate to construct a classifier for each cluster with similar features. The combination of factors with significant discrimination as input variables should outperform that with only single discriminative factor as input variable.
HIGH-RESOLUTION LINEAR POLARIMETRIC IMAGING FOR THE EVENT HORIZON TELESCOPE

Published: September 2016

Images of the linear polarizations of synchrotron radiation around active galactic nuclei (AGNs) highlight their projected magnetic field lines and provide key data for understanding the physics of accretion and outflow from supermassive black holes. The highest-resolution polarimetric images of AGNs are produced with Very Long Baseline Interferometry (VLBI). Because VLBI incompletely samples the Fourier transform of the source image, any image reconstruction that fills in unmeasured spatial frequencies will not be unique and reconstruction algorithms are required. In this paper, we explore some extensions of the Maximum Entropy Method (MEM) to linear polarimetric VLBI imaging. In contrast to previous work, our polarimetric MEM algorithm combines a Stokes I imager that only uses bispectrum measurements that are immune to atmospheric phase corruption, with a joint Stokes Q and U imager that operates on robust polarimetric ratios. We demonstrate the effectiveness of our technique on 7 and 3 mm wavelength quasar observations from the VLBA and simulated 1.3 mm Event Horizon Telescope observations of Sgr A* and M87. Consistent with past studies, we find that polarimetric MEM can produce superior resolution compared to the standard CLEAN algorithm, when imaging smooth and compact source distributions. As an imaging framework, MEM is highly adaptable, allowing a range of constraints on polarization structure. Polarimetric MEM is thus an attractive choice for image reconstruction with the EHT.

We present an analysis of high-quality photometry for globular clusters (GCs) in the Virgo cluster core region, based on data from the Next Generation Virgo Cluster Survey (NGVS) pilot field, and in the Milky Way (MW), based on Very Large Telescope/X-Shooter spectrophotometry. We find significant discrepancies in color–color diagrams between sub-samples from different environments, confirming that the environment has a strong influence on the integrated colors of GCs. GC color distributions along a single color are not sufficient to capture the differences we observe in color–color space.  While the average photometric colors become bluer with increasing radial distance to the cD galaxy M87, we also find a relation between the environment and the slope and intercept of the color–color relations.  A denser environment seems to produce a larger dynamic range in certain color indices. We argue that these results are not due solely to differential extinction, Initial Mass Function variations, calibration uncertainties, or overall age/metallicity variations.  We therefore suggest that the relation between the environment and GC colors is, at least in part, due to chemical abundance variations, which affect stellar spectra and stellar evolution tracks. Our results demonstrate that stellar population diagnostics derived from model predictions which are calibrated on one particular sample of GCs may not be appropriate for all extragalactic GCs.  These results advocate a more complex model of the assembly history of GC systems in massive galaxies that goes beyond the simple bimodality found in previous decades.

Published: September 2016

OBJETIVO: Avaliar o impacto do tempo de diagnóstico do Diabetes Mellitus Tipo 2 (DM2) sobre a qualidade de vida de idosos atendidos em Unidades Básicas de Saúde de Montes Claros/MG.MÉTODOS: Trata-se de estudo exploratório e descritivo com abordagem quantitativa e transversal. Foram entrevistados 201 idosos de 60 anos ou mais, portadores de DM2, utilizando um questionário que avalia aspectos socioeconômicos e relacionados ao DM2, formulado pelos pesquisadores e, o questionário SF-36, para avaliação da qualidade de vida. Foram agrupados os dados e os entrevistados divididos em dois grupos, conforme o tempo de diagnóstico do DM2 (menos de dez anos e mais de dez anos). As pontuações do questionário SF-36 foram convertidas em escores em oito domínios que foram comparados entre os grupos utilizando técnicas da estatística descritiva (cálculo da média e do desvio-padrão) e teste T Student para amostras independentes.RESULTADOS: A maioria dos entrevistados é do sexo feminino (57,70%), dentro da faixa etária de 60 a 69 anos (53,20%), casados (48,80%), com ensino fundamental incompleto (29,90%) e renda entre 1 e 4 salários mínimos (62,20%). O tempo de diabetes foi menor que 10 anos entre a maioria dos entrevistados (57,20%) e quando relacionado com a qualidade de vida, o grupo com mais de 10 anos de DM2 apresentou piores escores em todos os domínios do SF-36. Apenas o domínio Saúde mental não apresentou diferença estatisticamente significativa (p=0,243) entre os grupos. Os domínios Dor, Limitação por aspectos físicos e Capacidade funcional foram os mais afetados.CONCLUSÕES: Um tempo de diabetes maior que 10 anos demonstrou influenciar negativamente a qualidade de vida de idosos. O aumento da intensidade da dor e maior limitação física e emocional dos idosos podem ser considerados os fatores de maior influência na redução da qualidade de vida.

INVESTIGAÇÃO POR PLANEJAMENTO EXPERIMENTAL DA INFLUÊNCIA DA AGITAÇÃO E AERAÇÃO NO PROCESSO PRODUTIVO DE XANTANA POR Xanthomonas arboricola pv pruni
Authors: Alves-Gautério Fernanda Germano , Moreira Angelita Da Silveira , Vendruscolo Claire Tondo
Published: September 2016

Agitação e aeração em processos fermentativos de produção de xantana são variáveis necessárias para promover a oxigenação e evitar condições de anaerobiose, decorrentes da alta viscosidade do meio promovida pela formação desse biopolímero. Como existe interação entre essas variáveis, a combinação adequada deve ser determinada. Este trabalho objetivou avaliar os efeitos combinados da agitação e aeração, variáveis independentes, sobre o rendimento e a produtividade de xantana pruni, variáveis dependentes, mediante Delineamento Composto Central Rotacional (DCCR), como também acompanhar o processo em termos de pH, oxigênio dissolvido, biomassa, rendimento e atividade celulolítica. O DCCR foi composto de 22 ensaios + 4 ensaios nas condições axiais + 3 pontos centrais e as fermentações foram conduzidas em volume de 5L, em condições operacionais em acordo com a patente WO2006047845. Todos os ensaios foram influenciados pelas variáveis estudadas e apresentaram comportamento semelhante com o passar do tempo, porém com valores distintos. A agitação, variável mais influente, proporcionou em seus níveis mais elevados, favoravelmente, os maiores níveis de oxigenação, rendimento em xantana e produtividade, associados a maiores biomassa e menores reduções do pH e atividade celulolítica. Obtiveram-se modelos válidos para rendimento e produtividade e verificou-se que não é necessário manter as variáveis agitação e aeração nos níveis mais elevados, dentre os testados.

Published: September 2016

O leite é considerado um alimento completo, bem aceito e consumido por grande parte da população. O consumo de leite não pasteurizado (leite cru ou in natura) bem como seus derivados lácteos representam riscos ao consumidor em função da possibilidade da existência de patógenos. A comercialização informal de leite cru e derivados cresceu nas últimas décadas devido ao aumento da população e devido também ao valor de comercialização reduzido quando comparado com o leite beneficiado. O objetivo deste trabalho foi avaliar o perfil do consumidor de leite na cidade de Erechim, localizada na região do Alto Uruguai no estado do Rio Grande do Sul. O método utilizado foi uma pesquisa descritiva com a aplicação de um questionário a 332 distintos munícipes, o que representa 1% dos domicílios do município. Entre os meses de março e julho de 2011 foram entrevistadas 332 pessoas em 29 distintos bairros da cidade. O leite mais consumido pelos moradores de Erechim é o leite UHT ou “leite de caixinha” (46,26%). O leite cru é consumido por 20,07% da população, sendo a “origem familiar” a principal justificativa para o consumo. O principal derivado de leite consumido pelos erechinenses é o queijo sendo 34,03% da população consumidora deste alimento. Com relação à qualidade, 49,37%, consideram o leite comercializado ótimo. Os consumidores de leite do município de Erechim, RS têm hábito diversificado em relação ao consumo, sendo que 20,06% da população entrevistada é consumidora de leite cru ou in natura.

Published: September 2016

O objetivo deste estudo foi caracterizar a qualidade físico-química de leite, produtos lácteos e água e avaliar os rótulos dos alimentos produzidos por um laticínio localizado na cidade de Itapecuru-Mirim, Maranhão. Cinquenta amostras, sendo 18 de leite pasteurizado, 13 de queijos, 10 de bebida láctea, 02 de iogurte e, 07 de água, foram submetidas às análises físico-químicas. Os resultados das análises foram confrontados com as respectivas legislações em vigor. Foram avaliados também os rótulos das amostras de leite e derivados, comparando seus rótulos ao padrão proposto pela ANVISA, averiguando possíveis irregularidades. No período avaliado, apenas duas amostras, sendo uma de leite e outra de queijo, apresentaram parâmetros físico-químicos divergentes das legislações. Dos 43 rótulos avaliados, notou-se 30,23% de inadequações das informações obrigatórias. A principal irregularidade encontrada foi a ocorrência de vocábulos e/ou imagens induzindo ao equívoco o consumidor. Desta forma, conclui-se que a qualidade físico-química das amostras estava na sua maioria adequada aos padrões físico-químicos vigentes. Entretanto, as irregularidades observadas nos rótulos podem induzir o consumidor ao uso incorreto destes alimentos.

O objetivo deste trabalho foi realizar análises físico-químicas em polpas, sucos tropicais e néctares de manga para compará-los quanto à sua adequação aos Padrões de Identidade e Qualidade (PIQ) estabelecidos pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA). Seis amostras de polpas, sete de sucos tropicais (quatro não adoçados e três adoçados) e nove de néctares (seis convencionais e três light) foram analisadas quanto ao teor de sólidos solúveis (ºBrix), pH, acidez totale açúcares totais. Seguindo-se os parâmetros determinados por lei, as polpas também foram analisadas para concentração de sólidos totais, além do ratio. Dentre as bebidas, todas as marcas de sucos tropicais e néctares apresentaram resultados condizentes com a legislação em vigor. No entanto, o mesmo não ocorreu com as polpas, sendo que uma amostra apresentou valor de açúcares totais acima do máximo permitido, enquanto que outras duas apresentaram valores de sólidos totais abaixo do mínimo. Dentre vinte e duas amostras analisadas, três não atenderam as exigências da legislação brasileira. Isso mostra que a inadequação dos produtos de manga foi restrita a casos pontuais, representando, no presente estudo, 14%das amostras analisadas.

Use of biofilms in food enable increase of shelf life and ensure the conservation thereof. Chitosan has been used on obtainment of biofilms due its excellent properties of antimicrobial, antifungal, permeable and resistant film formation. The aim of this study was to evaluate the application effect of chitosan biofilms on conservation of sausages vacuum-packed or bulk packaging, stored at 10 °C for 10 days. For biofilm obtaining, chitosan (85% of deacetylation) was dissolved in acetic acid (0.5 mol L-1), at concentrations of 1% (T1) and 2% (T2). Sausages produced in industrial line were coating with T1 and T2 to immersion, stored at vacuum-packed or bulk packaging, and compared to a control (T3, without coating). Microbiologic analyses to determination of total and thermotolerant coliforms, mesophilic aerobic count, coagulase-positive Staphylococcus, and molds and yeasts were carried out during the storage at 10 °C, at times of 0, 14, 21 and 28 days, in order to study the antimicrobial and antifungal behavior of biofilm on the sausage. The biofilm showed no inhibitory action for mesophilic aerobic in all samples during the storage period. In molds and yeasts analyses were no significant difference between the samples T1, T2 and T3, for the vacuum packed sausages, indicating that the biofilm chitosan showed antifungal properties in the studied conditions. Further, in yeast count was observed that T2 was more effective inhibition than T1. In all experimental conditions, the coagulase-positive Staphylococcus count, and determination of total and thermotolerant coliforms showed values lower than 2 CFU g-1 and 0.3 MPN g-1, respectively. Application of chitosan biofilms in sausages can result in antifungal effect when associated to vacuum packing.

Published: September 2016

The quest for improved life quality has grown over the years, boosting research into the identification of bioactive substances in food. The polyphenols found in grapevines currently represent a broad area of research due to the benefits it has brought to people's health. This paper aimed to analyze whole grape, reconstituted and sweetened juice sold in the city of Bento Gonçalves and surrounding area to determine comparatively their levels of total polyphenols and resveratrol. This study consisted of eleven samples of grape juice from nine different brands. The samples were subdivided into whole grape juice, reconstituted grape juice and sweetened grape juice. The presence of resveratrol and polyphenols in each sample was determined by liquid chromatography and by reading a spectrophotometer at 280 nm, respectively. Variables with normal distribution were compared using the t-student test and Wilcoxon signed-rank test was applied to the nonparametric variables. Total polyphenol contents found in this study ranged from 18,50 to 107,95 mg/L. The highest average of polyphenols was found in the whole grape juice (85,71 mg/L), which is statistically higher (p = 0,009) than the one found in the sweetened juice (21,48 mg/L). The resveratrol content ranged from 0,45 to 2,60 mg/L, and no concentration was a found in the sweetened juice. The whole grape juice and the reconstituted juice showed the best results and therefore represent the best way to obtain these antioxidants and their benefits for the human body.

Wheat flour is widely used in human feeding. However, the production to supply internal demand is not sufficient in Brazil. In this context, this work aims the production and evaluation of lasagna pasta with partial replacement of wheat flour (FT) by cassava flour (FM). This way, Brazil's dependence of imported wheat can be reduced and a new and healthy food alternative can be produced from cassava. Fiber content of the product was increased adding 10% (dry basis) of eggplant flour (FB). Three fresh pasta of lasagna were developed with the following composition: M1 (control): 100% FT; M2: 60% FM; M3: 60% FM + 10% FB. Formulations M2 and M3 were characterized physical, chemical and physico-chemically. The results of fresh pasta M2 and M3 composition of showed that the product produced is rich in dietary fiber. The mean of scores assigned by the judges in sensorially evaluation of acceptance, for global impression, were classified between "liked moderately" and "liked much" for M1 and M2, and between "liked slightly" and "liked moderately" to M3.

Quality characteristics and sensory acceptance of sausages prepared with different percentages of MSM (mechanically separated meat) from chicken and added collagen fiber (CF), were evaluated in a central composite design using Response Surface Model for evaluation results. Sensory analysis was conducted by a group of 80 untrained panelists through a nine-point hedonic scale. The adjusted regression models were not significant (p> 0.05) for protein and moisture content and moisture/protein (M/P), but were significant (p<0.05) for fat and ash. For the collagen content, the model was adjusted, with significant quadratic effects for CF and MSM and the linear component for MSM. For the C/P ratio (collagen/protein) only linear effects MSM and CF were significant. Besides collagen content, the addition of MSM and CF significantly increased the C/P ratio, confirming the usefulness of this index for the classification of meat products. The MSM addition significantly affected all of sensory attributes evaluated, while the CF did not affect in any of them. It was possible to fit a quadratic model for linear models for appearance and flavor, texture and overall due to the addition of MSM. Larger quantities of MSM are associated with higher scores of preference for sausages and adding CF to 1% has no effect on the sensory acceptability.

The present work has as main objectives to optimize the extraction conditions of antioxidant phenolic compounds of the wine production of waste, prepared with Isabel and Bordô grapes (8:2) (Vitis labrusca) and evaluate soybean oil plus behavior of this extract through an accelerated storage test. The conditions that gave the extract with a higher content of total phenolics (TF) and the best antioxidant activity by the DPPH radical scavenging free method were dehydrating the residue at 80 °C and using 5.00 g of sample, 90 mL of ethanol/water 30% by magnetic stirring at room temperature for 4 hours (FT = 1222.68 ± 26.22 mg 100 g-1 AGE; IC50 = 876.78 ± 12.67 mg L-¹). This extract was added to soybean oil without antioxidants at concentrations of 1000 and 3000 ppm and the samples were subjected to an accelerated storage test at 65 °C for 17 days, compared to the synthetic antioxidant BHT (1000 ppm) and the antioxidant free oil as a negative control. The extracts were more effective than BHT in the oxidative stability of the oil in the first two days, delaying the formation of peroxides significantly. After 17 days, the BHT was able to inhibit by 51.2% the formation of peroxides in soybean oil, while the natural extract at a concentration of 3000 ppm inhibited by 27.0% and at concentration of 1000 ppm inhibited 24.0%, demonstrating the efficiency as natural antioxidant grape pomace extract.

Oatmeal liquid vegetable protein can be consumed by people intolerant to cow's milk. Produced a vegetable drink using oats as prebiotic and probiotic culture added (Lactobacillus acidophilus LA-5 (1x106UFC/g), Bifidobacterium BB-12 (1x106UFC/g) and Streptococcus thermophilus). Probiotic characteristics were evaluated of microorganisms and its physico-chemical quality. The formulation achieved by fermentation for five hours in an oven kept at a temperature of 42ºc, was characterized and compared to a probiotic yogurt commercial brand of cow's milk and oats. The drink produced presented pH of 4.82, acidity of 0.45%, 2 protein, 34 g/% and vitamin C (antioxidant) 7mg. The viscosity and consistency had typical result of yogurts. These values are similar to those reported in other studies for soy milk yogurts and milk cows. Lactic bacteria used in the preparation of the drink presented resistance to hydrochloric acid in the light of the minimum amounts established by the legislation in force. The prebiotic (oats) maintained the viability of lactic acid bacteria in the top level of the commercial sample, being required to characterize a food as probiotic. This study was obtained a symbiotic product, functional, nutritious and healthy.

Cassava bagasse, regarded as an agricultural residue can be used as raw material in the development of new products. Cereal bars are foods that have increasingly gained consumers because of the practical use. The objective of this study was to evaluate the effect of adding cassava bagasse (0, 8 and 25%) on the chemical composition and sensory acceptance of coconut cereal bars with Brazil nuts. Cereal bars with cassava bagasse had higher moisture, protein and carbohydrates (fiber) contents than cereal bars without bagasse, lower ash contents and similar fat content. The addition of cassava bagasse caused a decrease in the acceptance of the cereal bars only in the concentration of 25%, however, the products had hedonic values greater than 7 in a 9-point hedonic scale and acceptability indices higher than 80%, indicating that consumers moderately liked them. It can be concluded that the use of up to 25% cassava bagasse in the cereal bar formulation yields products with improved nutritional value and appropriated consumer acceptance. The addition of cassava bagasse to food products is a good alternative in the use of this byproduct, due to the sensory characteristics of the obtained products and the reduction of production costs, because the cassava bagasse has low cost and increases the production yield.

Breast Cancer is the most common form of cancer in Sri Lanka. Cancer is often curable if detected early. This study was conducted to investigate the level of knowledge of female undergraduates on prevention and control of breast cancer. Adopting the survey method, a semi- structured questionnaire was randomly distributed among 732 female undergraduates of three faculties of University of Moratuwa. Results revealed that the majority of the respondents have heard about breast cancer as well as some clinical features of breast cancer but their knowledge on risk factors of breast cancer and detection methods are not sufficient. They are aware about Breast Self-Examination (BSE) as a method of detection of breast cancer. However, majority do not know the technique of performing BSE. Their awareness about Well Woman Clinic is also low. Female undergraduates seek or encounter health related information through television, the Internet and newspapers as well as from medical officers. Majority do not believe the use of social media such as Facebook can be used to educate about breast cancers. Health education is vital in the university setup as undergraduates are future leaders. Regular awareness programmes to educate undergraduate about health aspects is the most preferred method.
The routine pre-employment screening chest radiograph: Should it be routine?
Authors: Samuel V John , Gibikote Sridhar , Kirupakaran Henry
Published: September 2016

Background and Objective: A routine chest radiograph is mandatory in many institutions as a part of pre-employment screening. The usefulness of this has been studied over the years keeping in mind the added time, cost, and radiation concerns. Studies conducted outside India have shown different results, some for and some against it. To our knowledge, there is no published data from India on this issue. Materials and Methods: A retrospective review of the reports of 4113 pre-employment chest radiographs done between 2007 and 2009 was conducted. Results: Out of 4113 radiographs, 24 (0.58%) candidates required further evaluation based on findings from the screening chest radiograph. Out of these, 7 (0.17%) candidates required appropriate further treatment. Interpretation and Conclusions: The percentage of significant abnormalities detected which needed further medical intervention was small (0.17%). Although the individual radiation exposure is very small, the large numbers done nation-wide would significantly add to the community radiation, with added significant cost and time implications. We believe that pre-employment chest radiographs should be restricted to candidates in whom there is relevant history and/or clinical findings suggestive of cardiopulmonary disease.
Holding versus seeing pathology. Three-dimensional printing of the bony pelvis for preoperative planning of a complex pelvis fracture: A case report
Authors: Sanghavi Parang S , Jankharia Bhavin G
Published: September 2016

Pelvic injuries are not uncommon. The complex anatomy of the pelvic bones, the complex pattern of injuries, associated important structures such as neurovascular bundles, and difficult access make the reduction and fixation of these fractures difficult. Often the surgical outcomes are not satisfactory. Three-dimensional (3D) imaging using computed tomography (CT) scan (3DCT) has been the mainstay of preoperative evaluation since the 1980s, however, even with these images it may be difficult to understand complex injury patterns. Preoperative printing of a 3D model using the same CT scan data allows surgeons to hold the pelvis in their hands and then plan appropriate treatment. We report one such case of complex pelvic injury and its management using the novel method of preoperative 3D model printing.
