Form of government in the interpretation of Russian pre-revolutionary lawyers
Authors: Morozova Lyudmila Alexandrovna
Published: October 2019

We consider the views of Russian scientists (I.A. Ilin, N.M. Korkunov, N.I. Lazarevskiy, I.L. Solonevich, L.A. Tikhomirov) regarding the form of government in Russia in the late 19th – early 20th century and the prospects for its development. The author states the merits of pre-revolutionary lawyers in creating a classification of government forms and in substantiating the features of the distinction between monarchical and republican forms of government, which modern theorists have not been able to fully implement. In pre-revolutionary jurisprudence there was no unity of opinion about the form of government established in Russia after the Manifesto of October 17, 1905. The researchers divided into two groups: one of them was made by scientists who considered the state system “the original Russian state order”, but only updated. According to another group, Russia has become a constitutional monarchy. I.L. Solonevich and I.A. Ilin made predictions about the inevitable collapse of the communist regime, so their thoughts were turned to the people who will remain on the ruins of the USSR and who will have to start a new state construction. At the same time, they proceeded from the fact that the Russian people have a sense of order, stability and great powerness. It is emphasized that all the analyzed scientists’ points of view paid great attention to the distinction between the concepts of absolute and autocratic monarchy, proving that absolutist arbitrariness and autocracy are not the same.

Published: October 2019

For a reliable evaluation of the geo-environmental risk due to naturally occurring asbestos (NOA) during rock excavation of large infrastructure projects, a proper procedure is needed. First, it is necessary to provide a detailed geological model tailored to the NOA-related issues that should drive the rock sampling procedures in order to obtain a representative sampling. The sampling procedures should take into account lithological variability and relative spatial distributions of the rock units. The geological model for NOA should be thus constrained by the main NOA petrofacies occurring in a given geotectonic context, which take into consideration both the mineralogical and structural features, and the identification of NOA homogeneous zones in which the NOA petrofacies are distributed. In this paper, some geo-environmental problems faced during the excavation, in meta-ophiolites, of a long highway tunnel are described. The geological model of the complex setting of the tunnel area (northern Italy, Alps-Apennines junction) is described, focusing on how the NOA-related problems were addressed to allow reliable and detailed estimations of NOA contents for each NOA homogeneous zone and the relevant tunnel layout segment.

Published: October 2019

Background. To investigate the similarities and differences in the structure and function of the central nerve system (CNS) among normal tension glaucoma (NTG), primary open-angle glaucoma with high intraocular pressure (HTG) and primary angle-closure glaucoma (PACG) patients. Methods. Ophthalmic examinations and multimodal magnetic resonance imaging (MRI) were performed. The results of brain functional connectivity (FC) were obtained based on the resting state MRI (rs-fMRI). Voxel-based morphometry (VBM) was applied to analyze structural images to obtain the volume change in the gray matter on 3D T1-weighted imaging (T1WI). Results. We found that frontal lobe FC increased in all three groups. Temporal lobe FC increased in the NTG group, while the FC of the cingulate gyrus and postcentral gyrus increased in the HTG and PACG groups by rs-fMRI. There were no gray matter volume changes in the NTG, while the gray matter of the frontal gyrus changed in the HTG and PACG. Moreover, the gray matter of the precentral gyrus changed in PACG, and the parietal lobe and supra marginal lobe changed in the HTG. The white matter of the inferior parietal lobe and postcentral gyrus increased, while that in the inferior temporal lobe decreased in the NTG group. The white matter in the HTG and PACG groups showed significant alterations in the medial occipital gyrus. Conclusions. The NTG group had different manifestations compared with the HTG and PACG groups regarding changes in brain structure and function, suggesting that pathogenic processes might differ between patients with normal-tension and high-tension POAG.
Comparisons of the Severity between the Kidney and Non-Kidney Disabled Persons by the Number of Chronic Diseases, Out-of-Pocket Expenditure, and Quality of Life: using Korea Health Panel
Authors: Shin Sun Mi , Lee Hee Woo
Published: October 2019

Background: Due to End-Stage Renal Disease, patients who have received dialysis for more than three months or who have already received a kidney transplant are eligible for registration as the Kidney Disabled in Korea. This study aimed to identify the severity between the Kidney and Non-Kidney Disabled by the number of chronic diseases, out-of-pocket expenditure, and quality of life. Methods: This study used the Korean Health Panel from 2009 to 2013. We compared the number of chronic diseases, out-of-pocket expenditure, and quality of life between the Kidney and Non-Kidney Disabled. The Non-Kidney Disabled included heart, liver, respiratory organ, colostomy or urostomy, and epilepsy. Chi-Square, t-test, and ANCOVA were conducted, and then the trends for five years were explored through panel analysis. Results: Of the 308 subjects, 136 (44.2%) had Kidney Disability and 172 (55.8%) had Non-Kidney Disabilities. The number of chronic diseases was 4.7 in the Kidney Disabled and 3.3 in the Non-Kidney Disabled (P<0.001). The annual out-of-pocket expenditure for the Kidney Disabled was $1,310 and that for the Non-Kidney Disabled $812 (P<0.001). Today’s subjective health status for the quality of life (from the worst 0 points to the best 100 points ) was 48.9 for the Kidney Disabled and 60.4 for the Non-Kidney Disabled (P<0.001). In addition, the five years trends for the number of chronic diseases, annual out-of-pocket medical expenditure, and quality of life also differed between the Kidney and the Non-Kidney Disabled (P<0.01). Conclusion: The Kidney Disabled was more serious than the Non-Kidney Disabled in the aspect of the number of chronic diseases, the out-of-pocket medical expenditure, and quality of life. Therefore, it is necessary to consider greater interest in the health care of the Kidney-Disabled people in terms of equity.

Published: October 2019

Background: The importance of global competence has been acknowledged in medical care as well as medical education. However, the existing definition of global competence and the survey tools used to assess global competence are not fully applicable to medical students. This study developed and validated a questionnaire assessing the global competence of medical students and preliminarily explored the underlying factors influencing the global competence of Chinese medical students in eight-year programs . Methods: A questionnaire (Global Competence Assessment Scale for Medical Students, MS-GCAS) was developed following a systematic process , and a cross-sectional multicent er survey was conducted among 10 medical schools in China. A total of 1062 completed questionnaires were analysed . Results: The analysis revealed a four-factor scale consistent with the proposed structure according to the definition of global compet ence . The validity estimates of the four subscales were mostly satisfactory. School education, duration of overseas exchange programs and willingness to work abroad were found to have significant correlation s with global competence .Conclusions: The MS-GCAS is valid and reliable for the assessment of the global competence of medical students in China. Medical schools should take further steps to promote medical students’ global competence .

Published: October 2019

Background: Although practice guidelines recommend colorectal cancer surveillance for inflammatory bowel disease (IBD) patients, the natural history of patient with dysplasia is poorly described. Assembling large cohorts of IBD patients with dysplasia is difficult as administrative codes are lacking. The aim of this study was to use natural language processing (NLP) in a large electronic health records (EHR) to identify IBD patients with colonic dysplasia. Methods: We conducted a retrospective cohort study using administrative data from the national Veterans Health Administration (VHA) Corporate Data Warehouse for patients with IBD. Full-text histopathology reports from patients who underwent colonoscopy in the VHA were obtained and a validation cohort was created using a random sample of 2000 reports. An NLP algorithm to identify the presence and grade of dysplasia was developed and performance tested in a validation cohort. The final NLP algorithm was applied to the entire IBD cohort to identify all cases of colonic dysplasia. Results: We identified a total of 44,099 Veterans with IBD, with 22,431 colonoscopy related histopathology reports. NLP had an accuracy of 97.1% for detection of low grade dysplasia, with a precision of 87%, recall of 96.6%, and F- measure of 91.5%. When applied to the entire cohort, a total of 1,762 cases of colonic dysplasia were identified. Conclusions: NLP accurately identifies colonic low-grade dysplasia in IBD patients from a national EHR. NLP can be used to identify large cohorts of IBD patients with dysplasia to further study the natural history and outcomes of colonic dysplasia in patients with IBD.

Authors: Tov Lior Shem , Ronel Ilai , Matot Idit
Published: October 2019

Background While special care is given to peri-operative risk assessment and management of the elderly undergoing surgery, psychological aspects have been largely neglected. Escort presence in the operating room (OR) is common practice in the surgical pediatric and obstetric populations, and may be beneficial in the elderly.Aims This study explored the feasibility of family member escort of the elderly into the OR and their presence until induction of anesthesia.Methods Prospective cohort of elderly patients (>70 years) undergoing surgery, who were offered an escort into the OR. The primary endpoint was the proportion of relatives who completed the intervention without feeling dizzy or fainting. Secondary endpoints related to patient, escort and medical staff perception of the process.Results Forty-four sets of patients and escorts completed the process. The primary objective assessing feasibility was concluded successfully. Secondary objectives assessed (1) satisfaction, where 93% of escorts and 75% patients would support a repeat of this process; (2) anxiolysis, where 61.4% of patients reported a reduced level of anxiety; (3) although 68.2% of anesthesiologists agreed this process improved that patients’ well-being, most anesthesiologists and nurses believed this should not become routine practice. Interestingly, most staff support parents escorting a pediatric patient into OR.Conclusion This is the first study exploring the feasibility of escorting the elderly into the OR. It shows a unique insight into patient- and family-centered care of the surgical elderly patient. Escort presence may help alleviate anxiety and increase satisfaction. The medical staff objections must be looked at further.
Association of MBOAT7-TMC4 rs641738 with the risk of hepatocellular carcinoma and persistent infection of hepatitis B virus: a case-control study and meta-analysis
Authors: Wang Peng , Zhou Yu , Li Lu , Gong Yajie , Zhong Rong , Shen Na
Published: October 2019

Background: Recent studies reported that a hot genetic variant, rs641738 within the membrane bound O-acyltransferase domain containing 7(MBOAT7) and transmembrane channel-like 4 (TMC4) , was associated with several liver diseases. However, results are still conflicting. We conducted this study to explore the role of MBOAT7-TMC4 rs641738 in the risk of hepatocellular carcinoma (HCC) and persistent hepatitis B virus (HBV) infection. Methods: We first performed a case-control study by including 779 HCC cases and 1412 cancer-free controls. Controls are consisted of 678 HBV persistent carriers and 734 spontaneously recovered subjects. Rs641738 was genotyped by MassARRAY platform. Results were analyzed by multivariate logistic regression analysis under five genetic models. Second, we conducted a systematic review and meta-analysis to further explore the role of this variant in HCC risk. Results: Results suggested no association between MBOAT7-TMC4 rs641738 and HCC risk in most genetic models (All P > 0.05), although a marginally significant association was observed in TT vs. CC ( P = 0.037) and recessive model ( P = 0.044). Further meta-analysis including 2135 HCC cases and 4388 controls supported that this variant was not related to HCC risk, even in the TT vs. CC and recessive models. Besides, we identified that this variant also had no influence on persistent HBV infection. Conclusion: Our work highlights that MBOAT7-TMC4 rs641738 is not associated with the risk of HCC or persistent HBV infection. This study provides some clues to identify the “truth” of potential disease-related genetic factors in the post-genome era.

Published: October 2019

Profissionais da saúde vivenciam altos níveis de estresse no trabalho ao lidar com emergências, cargas de trabalho excessivas, compartilhar perdas, sofrimento e óbito dos pacientes, e atuar em ambientes insalubres. Esses problemas diminuem a produtividade deles e os adoecem. Causam também substanciais prejuízos financeiros às organizações de saúde. Os profissionais de saúde podem enfrentar o desgaste físico e psicológico das condições ruins de trabalho, reduzindo riscos de ansiedade, depressão, transtorno pós-traumático e síndrome do burnout, utilizando técnicas de mindfulness, isto é, aumentando sua capacidade de atenção intencional à experiência do momento presente. O artigo discute o uso de protocolos de mindfulness no contexto hospitalar visando a capacitar os profissionais de saúde na solução efetiva de problemas e manejo de emoções. São recomendados especificamente protocolos de mindfulness que contemplem a criatividade, considerados mais adequados para enfrentar altos níveis de estresse contínuo.

Sağlık Sistemlerinde Karma Dağılım Modellerinin Uygulanması
Authors: KOYUNCU Melik
Published: October 2019

Sağlık sistemleri belirsizliğin genellikle fazla olduğu sistemlerden bir tanesidir. Örneğin bir hastanenin polikliniklerine gelen hasta sayısı, günün saatlerine göre değişkenlik gösterir. Hastane servislerinde bir hastanın kalış süresi, hastanın yaşı, cinsiyeti, başka bir hastalığı olup olmadığına bağlı olarak farklılık gösterir. Sağlık sistemlerinde, kapasite, personel vb. gibi planlamalar yapabilmek için, hasta geliş sayıları, hastanelerde kalış süreleri, ameliyat süreleri gibi parametrelerin tahmin edilmesi gerekir. Bu parametreleri tahmin etmek için kullanılan yöntemlere örnek olarak, talep tahmin yöntemleri, istatistiksel dağılım uydurma, makine öğrenmesi gibi yöntemler verilebilir. Bu yöntemlerden istatistiksel dağılım uydurma, belirli bir zaman diliminde toplanan verinin, teorik bir dağılıma uyup uymadığını test eder. Ancak belirsizliğin fazla olduğu durumlarda, yukarıda bahsedilen parametreleri saf bir istatistiksel dağılımla tahmin etmek her zaman mümkün olmayabilir. Bu çalışmada, heterojen yapıya sahip verilerin modellenmesinde kullanılan ve birden fazla dağılımın birleşmesiyle veya iç içe geçmesiyle oluşan karma dağılımların, sağlık sistemlerinde kullanılmasının, veri setine bağlı olarak, belirsizlikleri daha iyi modellediği gösterilmiştir.

Effects of Feature Extraction Techniques on Classification of Turkish Texts
Authors: AKDOĞAN Özge , ÖZEL Selma Ayşe
Published: October 2019

Feature extraction is the most important preprocessing step of text classification task. Effects of preprocessing techniques on text mining for English have been extensively studied. However, studies for Turkish are limited and generally belong to a specific problem domain. In this study, we investigate the effects of feature extraction techniques on four different Turkish text classification problems including news classification, spam e-mail detection, sentiment analysis, and author detection to show the differences and similarities among the problems. We also propose a new feature selection method to reduce feature space. The experimental analysis has showed that, stopword removal improves classification performance. However, stemming does not make any positive effect on classification accuracy. The most successful term weighting methods are tf and tf*idf. The proposed feature selection method improves classification performance and has higher accuracy than the well-known methods.

This study aims to determine the seasonal variability in the performance of a medium size population wastewater treatment plant (WWTP) in Bolivia. The semi-arid area where the WWTP is located is characterized as agricultural land, with an annual rainfall of 500 mm and a mean temperature of 17 °C. The WWTP is built up of five modules, each one comprising two treatment trains composed of an upflow anaerobic sludge blanket (UASB) reactor and horizontal gravel filter. The performance of the full process has been determined based on water quantity and quality. Seven monitoring campaigns of chemical and physical wastewater characteristics were performed from March to December 2017. The measured effluent showed average removal efficiencies of 83 ± 8% and 37 ± 60% for total chemical oxygen demand (COD) and total suspended solids (TSS), respectively. The treatment system has proven to be efficient to remove organic matter and TSS, despite the occurrence of high COD and total solids (TS) influent concentrations, the accumulation of solids at all the processes and the variability of flow and temperature inside the UASB reactors. In order to improve further this efficiency, it is recommended to implement a primary sedimentation unit as a pretreatment for the UASB system that would help to homogenize both the flow and the quality of the influent.

O processo antes da reforma: sobre algumas principais referências que subsidiaram a reforma do processo de Bolonha Europeu
Authors: Siebiger Ralf Hermes
Published: October 2019

O processo de Bolonha, movimento contemporâneo de reforma da educação superior europeia, tornou-se conhecido como tendo seu início a partir da assinatura das declarações de Sorbonne (1998) e Bolonha (1999). Contudo, essa reforma fundamenta--se também numa série de expedientes sobre educação superior que, desde os primeiros anos pós-segunda guerra mundial, foram emitidos conjuntamente às demais políticas de reconstrução e unificação do continente europeu. Considerando a incipiente menção a essas referências na literatura produzida no Brasil sobre o processo de Bolonha, a presente discussão busca apresentar algumas dessas principais referências, bem como evidenciar em que medida subsidiaram e mesmo foram incorporadas a essa reforma.
Conhecimento escolar: objeto incontornável da agenda política educacional contemporânea
Authors: Gabriel Carmen Teresa , Castro Marcela Moraes de
Published: October 2019

Este texto tem por objetivo apresentar argumentos teóricos que possam sustentar a aposta política no conhecimento escolar como objeto incontornável nas disputas pela construção de uma escola democrática. Em diálogo com as abordagens discursivas na perspectiva pós-fundacional incorporadas pelas teorizações curriculares recentes problematiza articulações discursivas entre significantes como conhecimento/cultura, universal/particular; conhecimento/conteúdo escolar e verdade/sentido presentes nos debates educacionais da atualidade. A análise aponta que o investimento, nos processos de produção de significados, é uma estratégia discursiva cujo potencial heurístico merece ser explorado. O argumento central afirma que, em tempos de escola "sob suspeita", o desafio político consiste também no posicionamento teórico em relação às lutas hegemônicas pela significação de termos, como o de “conhecimento escolar”, que são desestabilizados e recolocados no jogo político da definição.
As infâncias na creche −cenas do cotidiano
Authors: Dias Julice , Santos Luciana Mara Espíndola
Published: October 2019

Este artigo tem por objetivo dar visibilidade a questões emblemáticas em torno das infâncias vividas no espaço institucional creche. Imagens e concepções de infância e criança são problematizadas, com o objetivo de discutir por que e como ainda hoje temos tanta dificuldade de garantir às crianças o que lhes foi outorgado em lei, há tanto tempo − o direito à participação. Ancorada no aporte conceitual e metodológico da Sociologia da Infância, usa dos procedimentos etnográficos para captar as diferentes formas expressivas e modos de viver a infância na creche. Partindo do princípio de que as crianças são agentes sociais, problematiza o quanto práticas de silenciamento e, portanto, de invisibilidade do que as crianças dizem, fazem, brincam, sentem, pensam, ainda são engendradas nas instituições educativo-pedagógicas.
Nietzsche: tradição filosófica e educação
Authors: Lago Clenio
Published: October 2019

O emergir de Nietzsche no debate filosófico e educacional contemporâneos promoveu a necessidade de uma nova rearticulação da tradição filosófica e educacional, visto que seu pensamento lança e dá força ao paradigma estético, conferindo espaço às diversidades, desde a contraposição entre Apolo e Dionisio, dois grandes princípios artísticos estruturadores da cultura ocidental. Porém, a estimulação ininterrupta pela qual descambou a estética impossibilita e até impede a sensibilidade reflexiva. Assim, perguntando sobre o impacto do pensamento de Nietzsche na tradição filosófica em meio aos desafios contemporâneos, revisitaram-se e apresentaram-se as bases e os propósitos da estética nietzscheana, as implicações na educação, evidenciando o erro em ficarmos presos a um telos previamente definido. Ao mesmo tempo, chama a atenção para a rearticulação de tais fins em meio ao dinamismo da realidade, tornando imprescindível a dimensão estética como condição humana.

Published: October 2019

Este artigo explora aspectos das reformas educacionais que estão ocorrendo no Brasil, relacionando-os com uma ‘visão global’ que se aproxima das tendências e semelhanças que podem ser encontradas nas reformas educativas neoliberais em todo o mundo. Nós vamos delinear inúmeros processos inter-relacionados que se fazem presentes na escola como um local de trabalho, incluindo a intensificação do trabalho docente, a flexibilização da força de trabalho no ensino e a liberação da oferta de serviços na educação pública. O que será mostrado é que esses processos tem sido determinados por políticas neoliberais em escala global, por intermédio de uma combinação de privatizações endógenas e exógenas. As reformas que ocorrem no Brasil, e em muitos lugares, agem poderosamente não somente sobre as práticas e os valores da educação pública, mas também sobre as relações sociais no interior da escola e no entorno e para além do escolar. Elas tem um impacto significativo sobre o profissionalismo docente e opera para constituir docentes e suas subjetividades como performance e competição. Embora enfatizemos tendências gerais das reformas educativas neoliberais, também assistimos a algumas políticas locais específicas em inúmeros países.
As condições do trabalho docente na educação infantil no Brasil: alguns resultados de pesquisa (2002-2012)
Authors: Vieira Lívia Fraga , Oliveira Tiago Grama de
Published: October 2019

A partir de um levantamento bibliográfico inicial, que compreende o período entre 2002 e 2012, de artigos em periódicos disponibilizados pela base SciELO Brasil, de trabalhos apresentados nas reuniões anuais da ANPEd e de dissertações/ teses cujos resumos constam no Banco de Teses da Capes, produzimos um quadro com os principais fatores que constituem as circunstâncias condicionantes do trabalho docente em creches e pré-escolas brasileiras. Os resultados, obtidos a partir de descritores como “trabalho”, “educação” e “infantil”, foram classificados segundo os principais aspectos relacionados às condições de trabalho conforme a literatura na área: identidade/aspectos subjetivos, políticas públicas educacionais, condições profissionais e saúde/bem-estar. Constatamos que a realidade profissional das/os trabalhadoras/es da educação infantil no Brasil é marcada pela atribuição de obrigações que não possuem respaldo nas condições de realização fornecidas pelo poder público. Situações de estresse, mal-estar, adoecimento e insatisfação laboral foram frequentemente relatadas nos estudos.

Experiência da pedagogia freiriana na região rural do município de Coimbra (Portugal,1970)
Authors: Alcoforado Luís , Ferreira Sónia Mairos
Published: October 2019

No início da década de setenta do século XX, em pleno regime do Estado Novo, o Graal, um movimento internacional de mulheres católicas, desenvolveu um conjunto de atividades educativas na região rural do município de Coimbra, utilizando pela primeira vez, em Portugal, um programa planeado e desenvolvido de acordo com o pensamento e a experiência educativa de Paulo Freire.Este artigo pretende revisitar essas experiências de alfabetização, pós-alfabetização e animação social, utilizando os documentos produzidos pelo movimento,que suportavam teoricamente as intenções da sua intervenção social, os materiais produzidos para servirem de base ao desenvolvimento do programa e as memórias atuais de pessoas que vivenciaram essas experiências. Procura-se compreender a importância que, a esta distância temporal,as pessoas ainda atribuem a estas atividades incomuns, constatando-se o reconhecimento de um inegável impacto positivo nas pessoas e comunidades envolvidas.
Educação popular no contexto da globalização neoliberal
Authors: Figueiredo José Wnilson , Andrioli Liria Ângela , Frantz Walter
Published: October 2019

O presente artigo visa apresentar uma reflexão acerca da educação popular como uma prática possível à conjuntura social contemporânea. Trata-se de um uma conjuntura marcada pela racionalidade técnico-instrumental da globalização neoliberal, ancorada no individualismo, na homogeneização cultural e na monetarização da vida. Apoia-se em conceitos de educação popular, como uma alternativa possível, no que concerne à ética e à política, em favor de uma vida em que se insiram todos os seres humanos. Para tanto, tem-se, como ponto de partida, o diálogo intercultural em torno da ética e da esperança, em prol de possíveis caminhos, que possibilitem a emergência de uma civilização centrada na cooperação, ancorada no respeito às diferenças, na compaixão e na responsabilidade com o/a outro/a em oposição à lógica de mercado da educação da globalização neoliberal.

As políticas de formação de professores: a expansão comprometida
Authors: Maués Olgaíses Cabral , Segenreich Stella Cecilia Duarte , Otranto Celia Regina
Published: October 2019

O texto é resultado de pesquisa bibliográfica e tem como objetivo apresentar a análise referente aos cursos de Formação de Professores de forma presencial e a distância, realizados em instituições tradicionais de formação docente, bem como nos Institutos Federais. Os dados indicam redução de matrículas nas instituições tradicionais, se contrapondo a uma grande ampliação de oferta nos Institutos Federais, o que pode minimizar a escassez de docentes, apesar dos riscos apontados neste estudo relacionados à oferta de licenciaturas por instituições sem tradição na área.
O discurso da qualidade em periódicos internacionais e nacionais: uma análise crítica
Authors: Rothen José Carlos , Tavares Maria das Graças Medeiros , Santana Andreia da Cunha Malheiros
Published: October 2019

O artigo faz uma síntese sobre os conceitos de qualidade na educação superior, veiculados em periódicos nacionais e internacionais. Utiliza a metodologia da pesquisa bibliográfica para identificar a concepção de qualidade implícita ou explícita nos periódicos selecionados. Destaca que, nos periódicos europeus, a qualidade da educação está intimamente vinculada à constituição da Comunidade Europeia e do Processo de Bolonha. Afirma que, nos periódicos latinos, há uma tendência a associar qualidade da educação à avaliação e à formação para o mercado de trabalho, enquanto, nos periódicos brasileiros, a qualidade é vista como estratégia de controle e regulação exercida pelo Estado, especialmente por meio da avaliação.

:

Among the ophidians that inhabit the Northeast of Argentina, the genus Bothrops such as B. alternatus and B. diporus species (also known as yararás) and Crotalus durisus terrificus (named cascabel), represent the most studied snake venom for more than thirty years. These two genera of venomous snakes account for the majority of poisonous snake envenomations and therefore, constitute a medical emergency in this region. This review presents a broad description of the compiled knowledge about venomous snakebite: its pathophysiological action, protein composition, isolated toxins, toxin synergism, toxin-antitoxin cross-reaction assays. Properties of some isolated toxins support a potential pharmacological application.
Utilization of Microfluidics for the Preparation of Polymeric Nanoparticles for the Antioxidant Rutin: A Comparison with Bulk Production
Authors: Vu Hanh T.H. , Streck Sarah , Hook Sarah M. , McDowell Arlene
Published: October 2019

Objective:

To compare the characteristics of rutin-loaded PLGA (poly(lactic-coglycolic
acid)) nanoparticles prepared using a single emulsion evaporation method (bulk
method) and a nanoprecipitation method using microfluidics.

Method:

Rutin-loaded PLGA nanoparticles were produced using different methods and
characterized for size, zeta potential, entrapment efficiency (EE) and drug loading (DL). A
design of experiments approach was used to identify the effect of method parameters to optimize
the formulation. DSC was used to investigate the solid-state characteristics of rutin
and PLGA and identify any interactions in the rutin-loaded PLGA nanoparticles. The release
of rutin from PLGA nanoparticles was examined in biorelevant media and phosphate
buffer (PBS).

Results :

The optimal formulation of rutin-loaded PLGA nanoparticles produced using a
microfluidics method resulted in a higher entrapment efficiency of 34 ± 2% and a smaller
size of 123 ± 4 nm compared to a bulk method (EE 27 ± 1%, size 179 ± 13 nm). The solidstate
of rutin and PLGA changed from crystalline to amorphous with the preparation of rutin-
loaded PLGA nanoparticles. More importantly, using microfluidics, rutin released faster
from rutin-loaded PLGA nanoparticles in biorelevant media and PBS with higher burst
release compared to the rutin release from the nanoparticles prepared by using the bulk
method.

Conclusion:

Rutin can be encapsulated in nanoparticles formulated with different methods
with mean sizes of less than 200 nm. Microfluidics produced more uniform rutin-loaded
PLGA nanoparticles with a higher EE, DL and faster release compared to a bulk production
method.
The Effect of Sea State on the Polarization of Reflected Beidou B1 Signals
Authors: Lyu Tingting , Sha Shuang , Zhang Min , Zhang Hao , Gulliver Thomas A.
Published: October 2019

Background:

Oceanographic buoys generally employ satellites for positioning and data
transmission. However, sea surface conditions can affect these signals. The Signal to Noise Ratio
(SNR) of small observation buoys can be improved by exploiting polarization diversity.

Methods:

This paper discusses the effect of sea surface conditions on the polarization and reflection
loss of Beidou B1 reflected signals for the purposes of exploiting polarization diversity. The
Rayleigh roughness criterion is used to assess the roughness of the sea surface. The Fresnel reflection
coefficients are derived to analyze the polarization and reflection loss of the Beidou B1 reflected
signals with different sea surface states.

Results:

The results obtained show that for the Beidou B1 signals, the sea surface is considered
rough for most sea surface states and incident angles. For smooth sea surfaces, the Beidou B1 reflected
signals are mainly Left Hand Circularly Polarized (LHCP) waves, but Right Hand Circularly
Polarized (RHCP) waves dominate when the incident angles are larger than the Brewster angle.
The reflected loss is between -2 dB to -3.4 dB. In rough sea surfaces and the signals propagation is
dominated by diffuse reflection. The reflection loss decreases with the incident angle and there is a
fluctuation when the incident angle is around 49 degrees. The specular reflection signal has a significant
amplitude when the angle of incidence is large. RHCP waves are the main component of
the reflected signals, and the reflection loss is relatively small which can be employed for polarization
diversity or marine remote sensing.

Conclusion:

polarization diversity is only useful with good sea conditions, and the corresponding
gain decreases with the deterioration of the sea surface conditions.

The objective was to investigate the effects of blast chilling on pork quality in cuts from the Longissimus thoracic et lumborum (LM), Psoas major (PM), Semimembranosus (SM; both superficial [SMS] and deep [SMD] portions) and the Triceps brachii (TB). Forty carcasses (10 carcasses per replication) were split and sides were assigned to either blast chill (BC, –32°C for 90 min, followed by spray chill at 2°C for 22.5 h) or conventional chill (CC, spray chilled at 2°C for 24 h) regimens. The LM from BC sides had lower (P < 0.05) temperature at 2 h postmortem (CC 21.8°C, BC 9.7°C), 4 h (CC 13.3°C, 3.8°C BC), 22 h (CC 4.2°C, BC 1.4°C), and 30 h (CC 0.4°C, BC –0.2°C). The LM pH in BC sides was higher at 4 h (CC 6.09, BC 6.34), 22 h (CC 5.81, BC 5.89), and 30 h (CC 5.68, BC 5.74) postmortem. The BC resulted in higher (P < 0.05) 30 h postmortem pH in the SM compared to the CC regime (CC 5.68, BC 5.74). The BC sides had increased (P < 0.05) purge in the PM (CC 0.48%, BC 0.74%) and increased (P < 0.05) cook loss in chops from the LM (CC 22.37%, BC 24.24%). The PM from BC sides were more juicy (CC 7.50, BC 8.30), less chewy (CC 2.80, BC 2.10), and more tender (CC 7.90, BC 8.60). Chops from the LM of BC sides had greater Warner-Bratzler shear force (CC 2.00, BC 2.30). Color was affected in the SM with BC sides showing darker color score (CC 3.00, BC 3.20) and redder Hunter a value (CC 16.35, BC 16.02). Chilling treatment did not affect sarcomere length in the LM. Treatment did not affect postmortem proteolysis in any cut. The response to chilling regimen is different across different muscles which may be caused by location, rate of chilling, and fiber type.
