Use of Recycled Aggregates made from Construction and Demolition Waste from Structural Concrete such as Graded Aggregate and Cement Soil in Sustainable Road Infrastructures Base Layers
Authors: Teijón-López-Zuazo Evelio , Vega-Zamanillo Ángel , Calzada-Pérez Miguel Ángel , Robles-Miguel Ángel
Published: April 2020

Construction and demolition waste (CDW) represents 1/3 of the weight of all-waste produced. Increasing their recycling and reutilization with recycled aggregates (RA) means closing the life cycle of construction materials. Research has been carried out on artificial aggregates from the exclusive crushing of structural concrete waste in selective demolitions (CDWRConc). This study analyses the use of recycled concrete as graded aggregate (GARConc) and in cement soil (CSRConc). The material complies with the requirements as a road base, although due to the low values of resistance to fragmentation these materials are adequate for use in sensitive road systems and other places such as urban roads and car parks. The sensitive road systems are infrastructures in places of great natural wealth and low traffic intensity, with an annual average of heavy vehicle traffic (AADTh) below 50 vhp/d. As soluble salt contents have been detected, additional waterproofing or drainage measures must be adopted to prevent water infiltration into the layers made up of CDWRHorm. Finally, the high initial values of UCS allow the temporary passage of light vehicles over CSRConc after 3 days.
The Stethoscope, Respiratory Examination and Lung Ultrasound in the COVID-19 Era
Authors: Aujayeb Avinash
Published: April 2020

The current Covid-19 pandemic has hugely disrupted the delivery of routine and established medical care. Patients can develop a wide range of clinical signs and symptoms from a cough and fever to severe respiratory failure. There is an ongoing argument on a concise investigative pathway to ensure the safety of all healthcare workers. The stethoscope can help with any clinical respiratory assessment but the risk of cross infection is high. Computer tomography should not be routinely performed. There is a potential place for lung ultrasound but outcomes are not yet determined.

Published: April 2020

Casein hydrolysate improves arterial stiffness, as estimated by brachial ankle pulse wave velocity (baPWV), in untreated hypertensive subjects. Facial pigmentation is a useful biomarker for arterial stiffness. This trial evaluated whether casein hydrolysate improves facial pigmentation in association with changes in arterial stiffness. A randomized, double-blind, placebo-controlled trial was conducted in 80 non-hypertensive Japanese participants randomly assigned to receive either active tablets containing casein hydrolysate or placebo for 48 weeks. Facial pigmentation and baPWV were measured at baseline and at the end of the intervention. Other biochemical atherosclerosis-related parameters were also measured, including advanced glycation end products (AGEs). Changes in facial pigmentation showed a significant difference between the groups. Change in baPWV was significantly better in the active than in the placebo group. In contrast, no significant association was seen between changes in facial pigmentation and those in baPWV. Among other atherosclerosis-related factors, changes in advanced glycation products (AGEs) were significantly decreased in the active compared to the placebo group. Further, changes in facial pigmentation were positively correlated with those in AGEs. Changes in AGEs were independently associated with changes in facial pigmentation. Casein hydrolysate improves facial pigmentation in non-hypertensive participants. Casein hydrolysate may have beneficial effects on glycation stress.

Published: April 2020

The world has been evolving with new technologies and advances day-by-day. With the advent of various learning technologies in every field, the research community is able to provide solution in every aspect of life with the applications of Artificial Intelligence, Machine Learning, Deep Learning, Computer Vision, etc. However, with such high achievements, it is found to lag behind the ability to provide explanation against its prediction. The current situation is such that these modern technologies are able to predict and decide upon various cases more accurately and speedily than a human, but failed to provide an answer when the question of why to trust its prediction is put forward. In order to attain a deeper understanding into this rising trend, we explore a very recent and talked-about novel contribution which provides rich insight on a prediction being made -- ``Explainability.'' The main premise of this survey is to provide an overview for researches explored in the domain and obtain an idea of the current scenario along with the advancements published to-date in this field. This survey is intended to provide a comprehensive background of the broad spectrum of Explainability.

Introduction: Coronavirus 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2. The majority of patients have at most mild symptoms, however, a significant proportion develops respiratory failure. COVID-19 may also progress beyond the lungs. Coagulopathy and thromboembolism are prevalent in severe COVID-19 and relate to decreased survival. Coagulation is an intricate balance between clot promoting and dissolving processes in which vitamin K plays a well-known role. We hypothesized that vitamin K status is reduced in patients with severe COVID-19. Methods: Vitamin K status was assessed by measuring desphospho-uncarboxylated matrix Gla protein (dp-ucMGP; inversely related to vitamin K status) and the rate of elastin degradation by measuring desmosine. We included 123 patients who were admitted with COVID-19 and 184 controls. Results: Dp-ucMGP levels were significantly elevated in COVID-19 patients (1,673Å}1,584 pmol/L) compared to controls (536±291 pmol/L; p<0.0005). Dp-ucMGP levels were significantly higher in COVID-19 patients with unfavorable outcome compared to those with less severe disease. Furthermore, dp-ucMGP and desmosine levels were significantly associated (r=0.65; p<0.0005). Conclusions: Vitamin K status was reduced in patients with COVID-19 and related to poor prognosis. Also, low vitamin K status seems to be associated with accelerated elastin degradation. An intervention trial is now needed to assess whether vitamin K administration improves outcome in patients with COVID-19.

Published: April 2020

This study was conducted to determine whether overcrowding in the emergency department (ED) affects the occurrence of a return visit (RV) within 72 hours. The crowding indicator of index visit was the average number of total patients, patients under observation, and boarding patients during the first 1 and 4 hours from ED arrival time and the last 1 hour before ED departure. Logistic regression analysis was conducted to determine whether each indicator affects the occurrence of RV and post-RV admission. Of the 87,360 discharged patients, 3,743 (4.3%) returned to the ED within 72 hours. Of the crowding indicators pertaining to total patients, the last 1 hour significantly affected decrease in RV (p=0.0046). Boarding patients were found to increase RV occurrence during the first 1 hour (p=0.0146) and 4 hours (p=0.0326). Crowding indicators that increased the likelihood of admission post-RV were total number of patients during the first 1 hour (p=0.0166) and 4 hours (p=0.0335) and evaluationg patients during the first 1 hour (p=0.0059). Overcrowding in the ED increased the incidence of RV and likelihood of post-RV admission. However, overcrowding at the time of ED departure was related to reduced RV.

This review chronicles the indirect transmission method which seems to be overlooked by most people and makes attempts to clearly document the various transmission ways with a hope that such information may strengthen the knowledge base of researchers towards methods of eradicating the pandemic. Current knowledge of transmission and exposure of SARS-CoV-2 has been explained. Various researchers have put forward different ways of exposure and transmission. Literature does not reveal whether the indirect transmission route is the dominant one. However total lockdown could be a veritable means to reduce both direct and indirect transmission routes. In many countries where the indirect transmission has been reduced, the scourge of the virus is less. The work creates awareness on the need to watch out for those routes of transmissions that may not be popular and suggested key knowledge gaps that needs to filled.
Characterization of Shear Strain on PDMS: Numerical and Experimental Approaches
Authors: Souza Andrews , Marques Eduardo , Balsa Carlos , Ribeiro João
Published: April 2020

Polydimethylsiloxane (PDMS) is one of the most popular elastomers and has been used in different fields, especially in biomechanics research. Among the many interesting features of this material, its hyperelastic behaviour stands out, which allows the use of PDMS in various applications, like the ones that mimic soft tissues. However, the hyperelastic behaviour is not linear and needs detailed analysis, especially the characterization of shear strain. In this work, two approaches, numerical and experimental, were proposed to characterize the effect of shear strain on PDMS. The experimental method was implemented as a simple shear testing associated with 3D digital image correlation and was made using two specimens with two thicknesses of PDMS (2 and 4 mm). A finite element software was used to implement the numerical simulations, in which four different simulations using the Mooney-Rivlin, Yeoh, Gent, and Polynomial hyperelastic constitutive models were performed. These approaches showed that the maximum value of shear strain occurred in the central region of the PDMS, and higher values emerged for the 2 mm PDMS thickness. Qualitatively, in the central area of the specimen, the numerical and experimental results have similar behaviours and the values of shear strain are close. For higher values of displacement and thicknesses, the numerical simulation results move further away from experimental values.
Theoretical Analysis of the Induction of Forced Resonance Mechanical Oscillations to Virus Particles by Microwave Irradiation:Prospects as an Anti-virus Modality
Authors: Uzunoglu Nikolaos
Published: April 2020

The induction of acoustic-mechanical oscillations to virus particles by illuminating them with microwave signals is analyzed theoretically. Assuming the virus particle being of spherical shape, its capsid consisting primarily of glycoproteins, a viscous fluid model is adopted while the outside medium of the sphere is taken to be ideal fluid. The electrical charge distribution of virus particle is assumed to be spherically symmetric with a variation along the radius. The generated acoustic-mechanical oscillations are computed by solving a boundary value problem analytically, making use of the Green’s function approach. Resonance conditions to achieve maximum energy transfer from microwave radiation to acoustic oscillation to the particle is investigated. Estimation of the feasibility of the technique to compete virus epidemics either for sterilization of spaces and/or use for future therapeutic applications is examined briefly.

Authors: Al-Fadhel Suhaer Zeki , Al-Ghuraibawi Nibras H. Abdulsada , Mohammed Ali Dunia M. , Al-Hakeim Hussein Kadhem
Published: April 2020

Type 2 diabetes mellitus (T2DM) is an endocrine illness associate with various changes in the immune system and adaptor protein levels. Cytokine dependent hematopoietic cell linker (CLNK) is an adapter protein that regulates immune receptor signaling and acts as a regulator of the receptor signaling of T-cells and natural killer T-cell. The role of CLNK in T2DM is not studied previously. In the present study, serum CLNK level was measured and correlated with some sociodemographic and insulin resistance (IR) parameters. This is achieved by performing measurement of CLNK and insulin parameters (glucose, insulin, and HbA1c in addition to the calculation of the functions of IR (HOMA2IR), insulin sensitivity (HOMA%S), and beta-cell function (HOMA%B)) in 60 T2DM patients and 30 controls. The results indicated a significant increase (p=0.025) in serum CLNK in patients group in comparison with the controls. Multivariate generalized linear model (GLM) analysis revealed no significant effect of age, BMI, and sex on the CLNK level. The results of tests for between-subjects showed that the CLNK affects diagnosis significantly (F=7.445, p=0.008, partial η2 =0.081) and its effect is approximately the same as the effect of insulin (F=8.107, p=0.006, partial η2 =0.087). The correlation study showed a highly significant positive correlation between CLNK and the duration of disease (rho=0.420, p<0.001). It can be concluded that the increase CLNK in T2DM revealing the role of the adaptor proteins level in the nature of disease. Elevation of CLNK level may be used as a predictor for diabetes complications, which needs more investigations.

Published: April 2020

Background: The mortality and severity in COVID-19 is increased in patients with comorbidities. The aim of this study was to evaluate the unknown risk of severity and mortality in COVID-19 patients with underlying kidney and liver diseases. Method: We retrieved data on the clinical features and primary composite end point of COVID-19 patients released from inception till 16th of April 2020 from Medline and Embase. The data on two comorbidities, liver diseases and chronic kidney disease, present in COVID-19 were pooled and statistically analysed to explain the associated severity and mortality rate. Results: 142 abstracts were screened, and 41 full articles were then read. In total, 22 studies including 5595 COVID-19 patients were included in this study with case fatality rate of 16%. The prevalence of liver diseases and CKD were 3% (95%CI; 2%-3%) and 1% (95%CI; 1%-2%) respectively. In patients with COVID-19 and underlying liver diseases, 57.33% (43/75) cases were severe with 17.65% mortality. While in CKD patients with COVID-19, 83.93% (47/56) severity and 53.33% (8/15) mortality were reported. Conclusion: This study found an increased risk of severity and mortality in COVID-19 patients with liver diseases and CKD. This will allow for better clinical management and inform more stringent preventative measures for this group of patients.
A Proposed Framework for Efficient and Cost-Effective Terrestrial Orchid Conservation
Authors: Brundrett Mark
Published: April 2020

This paper presents a comprehensive and adaptive framework for orchid conservation programs illustrated with data from published and unpublished case studies. There is a specific focus on West Australian terrestrial orchids, but many of the approaches have universal relevance. Aspects of the framework include (1) setting appropriate objectives, (2) establishing effective collaborations between scientists, volunteers and regulators to fill knowledge and funding gaps, (3) use of survey and demographics data to determine extinction risks and management requirements for species, (4) effective habitat management to overcome threats such as grazing, (5) finding potential new habitats by modelling climate and site data, (6) investigating the effectiveness of pollinators and (7) using seed baiting to detect mycorrhizal fungi. The relative cost and effectiveness of different methods used to propagate orchids for translocation are compared. Methods known to be successful, in order of complexity, include placement of seed in situ, vegetative propagation, symbiotic germination in non-sterile organic matter, symbiotic germination in sterile culture, asymbiotic sterile germination and clonal division in tissue culture. These form a continuum of complexity, cost, time required, faculties needed, as well as the capacity to maintain genetic diversity and produce seedlings preadapted to survive in situ. They all start with seed collection and lead to seed storage, living collections used as tuber banks and seed orchards, as well as translocation for conservation. They could also lead to commercial availability and sustainable ecotourism, both of which are needed to reduce pressure on wild plants. Overall, there has been a strong preference to use relatively complex, expensive and time-consuming methods for orchid conservation, despite evidence that simpler approaches have also been successful. These simpler methods, which include in situ seed placement and non-sterile germination on inorganic substrates, should be trialled in combination with more complex orchid propagation methods as part of an adaptive management framework. It is essential that orchid conservation projects harness the unique biological features of orchids, such as abundant seed production and mycorrhizal fungi which are far more widespread than their hosts. This is necessary to increase the efficiency and coverage of recovery actions for the largest and most threatened plant family.

Authors: Yang Xiaomei , Zhao Hongjin , Li Yan , Zhang Peng
Published: April 2020

Recently, the outbreak of coronavirus disease 2019 (COVID-19) is threatening human health globally. There is a dire need to find potential therapeutic agents. Angiotensin converting enzyme 2 (ACE2), as an entry receptor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is considered as potential therapeutic target in COVID-19 pandemic. Here, our bioinformatics analysis revealed that the biological function of ACE2 was correlated with regulation of blood pressure and mediation of SARS-CoV-2 entry into host cells. Ten ACE2 cooperative proteins were identified by using STRING with a high score. ACE2 expressed highly in the small intestine, testis, and kidney. The level of ACE2 expression in tumor tissues varies in different types of cancers compared with that in normal tissues. It was worth noting that the expression level of ACE2 in the tumor has no effect on patient survival. MiRNA hsa-miR-942-5p, and three transcription factors (TFs) including Signal transducer and activator of transcription 4 (STAT4), Estrogen related receptor α (ESRRA), and Signal transducer and activator of transcription 3 (STAT3) were selected as novel ACE2 regulators. Moreover, nine potential therapeutic drugs were predicted by two online databases. Thus, our research may expand the overall view of ACE2 in COVID-19 treatment.
Liberal Oxygen with Unreliable Unpredictable Flowrate Is the Root Cause of Unexplained Physiological Events in Combat aircraft
Authors: Bassovitch Oleg
Published: April 2020

Over the last 20 years, there has been a significant increase in the number of unexplained physiological events (UPEs) reported by pilots of fighter jets across different fleets. The UPEs have resulted in grounding some types of aircraft, loss of airplanes, and even loss of life. Despite considerable research, no single agreed-upon root cause has been found that explains UPEs, and therefore no reliable corrective actions exist. The purpose of this review was to analyze the literature related to other industries in which artificial hyperoxic gas mixes are employed and similar adverse reports have been reported. Based on analysis of the literature, it is hypothesized that UPEs are caused by unlimited delivery of high-dose oxygen in excess of officially approved oxygen schedules in the presence of inadequate airflow rates, at a time when the positive pressure breathing feature of their oxygen regulator system is not used. During flight maneuvers such as climbs, turns, and descents, pulmonary vital capacity is impaired by G-maneuvers and oxygen- and G-induced atelectasis. At the same time, tidal volume is reduced by flight gear, and effective gas exchange is not supported by adequate ventilation. These factors combine to produce hypercarbia, respiratory acidosis, acute respiratory distress syndrome, CO2 narcosis, and coma. In fact, reports from field data related to incidents in F-18S/H, showing that emergency oxygen did not correct the hypoxia-like symptoms including long-lasting periods of incapacitation and prolonged headaches, lend support to this hypothesis.
Inflation of Universe by Nonlinear Electrodynamics

Published: April 2020

Nonlinear electrodynamics with two dimensional parameters is studied. The range of electromagnetic fields when principles of causality, unitarity and the classical stability hold are obtained. A singularity of the electric field at the center of charges is absent within our model and there are corrections to the Coulomb law as $r\rightarrow\infty$. The universe inflation takes place in the background of stochastic magnetic fields. The second stage of the universe evolution is the radiation era so that the graceful exit exists. We estimated the spectral index, the tensor-to-scalar ratio, and the running of the spectral index that are in an approximate agreement with the PLANK and WMAP data.

The technology-driven world of the 21st century is currently confronted with a major threat to humankind in the form of the coronavirus disease (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). As of April 22, 2020, COVID-19 has claimed 169, 006 human lives and had spread to over 200 countries with more than 2,471,136 confirmed cases. The perpetually increasing figures associated with COVID-19 are disrupting the social and economic systems globally. The losses are unmatched and significantly higher compared to those from previously encountered pathogenic infections. Previously, two CoVs (SARS-CoV and Middle East respiratory syndrome-CoV) affected the human population in 2002 and 2012 in China and Saudi Arabia, respectively. Based on genomic similarities, animal-origin CoVs, primarily those infecting bats, civet cats, and pangolins, were presumed to be the source of emerging human CoVs, including the SARS-CoV-2. The cohesive approach amongst virologists, bioinformaticians, big data analysts, epidemiologists, and public health researchers across the globe has delivered high-end viral diagnostics. Similarly, vaccines and therapeutics against COVID-19 are currently in the pipeline for clinical trials. The rapidly evolving and popular technology of artificial intelligence played a major role in confirming and countering the COVID-19 pandemic using digital technologies and mathematical algorithms. In this review, we discuss the noteworthy advancements in the mitigation of the COVID-19 pandemic, focusing on the etiological viral agent, comparative genomic analysis, population susceptibility, disease epidemiology, animal reservoirs, laboratory animal models, disease transmission, diagnosis using artificial intelligence interventions, therapeutics and vaccines, and disease mitigation measures to combat disease dissemination.
Relações interculturais e o trabalho de tradução como cartografia: subjetividade, transparência e poder
Authors: Bona Juliano , Luna José Marcelo Freitas de
Published: April 2020

A pós-modernidade está saturada de forças que não pertencem a nenhuma geografia. As fronteiras culturais desaparecem diante da avalanche de informações que circulam de forma intercontinental. Observar o que está dentro e o que está fora de uma determinada cultura é um dos desafios de quem se propõe a traduzir as relações interculturais em nosso momento histórico. Não se trata apenas de localizar as fronteiras interculturais, mas, ao invés e também, pensar no próprio conceito de cultura como expressão da diferença em um sentido não reacionário. Deste modo, o objetivo geral deste artigo é analisar o trabalho de tradução intercultural em um contexto pós-moderno. Estamos diante de um ensaio teórico. Inicialmente, descrevemos os movimentos sociais pós-modernos e sua agenda estruturante. Em seguida, observamos as micro relações que nos permitem pensar nas fronteiras subjetivas interculturais, no que se refere à transparência e ao poder que age na positividade, nos agenciamentos desejantes. Posteriormente, discutimos o trabalho de tradutor intercultural diante do que sobra, o flerte com o poder, a cartografia.
A Biblioteca e a construção do trabalho educativo na escola
Authors: Farias Fabíola Ribeiro , Britto Luiz Percival leme , Santos Zair Henrique
Published: April 2020

O artigo aborda a contribuição da biblioteca escolar no trabalho educativo, a partir do entendimento do filósofo alemão Theodor W. Adorno de que a educação tem como fim último a recusa da barbárie. Para isso, toma o conceito de trabalho educativo da pedagogia histórico-crítica e a concepção de biblioteca escolar de Álvarez e Castrillón (2013) para discutir distintas concepções de biblioteca escolar, com ênfase na formação de acervos bibliográficos. Conclui que embora haja avanços na área, ainda há lacunas, especialmente no que toca às distâncias teóricas e práticas entre educação e biblioteconomia, e que a biblioteca escolar pode contribuir para a ampliação do capital cultural de estudantes e professores.
Das liberdades públicas aos direitos fundamentais: um estudo do caso francês
Authors: Rezende de Souza Pinto Gabriel
Published: April 2020

Este artigo examina o processo de expansão mundial dos direitos fundamentais, estudando a introdução deste conceito na França da segunda metade do séc. 20. O caso francês exibe algumas particularidades importantes, notadamente em sua resistência ao que, para alguns, pareceu uma assimilação apressada de uma cultura jurídica estrangeira. Esse conflito operativo será discutido de forma esquemática, contrastando-se a teoria dos direitos fundamentais, de origem alemã, e a autóctone teoria das liberdades públicas — derivada dos desenvolvimentos históricos do Direito Administrativo francês —. Por meio de revisão da literatura corresponde ao tópico, mostrarei não apenas de que modo as instituições europeias promoveram uma ideia bastante específica dos direitos fundamentais, mas também as razões que levaram esta última à hegemonia no campo jurídico.
A Lei de Introdução às Normas do Direito Brasileiro e a ampliação dos parâmetros de controle dos atos administrativos: um novo paradigma
Authors: Vitorelli Edilson
Published: April 2020

Este texto explora os horizontes do controle dos atos administrativos a partir dos novos dispositivos da Lei de Introdução às Normas do Direito Brasileiro (LINDB), aprovados em 2018. Demonstra-se que a lei promove uma ampliação dos parâmetros de controle de legalidade, abandonando, em definitivo, a ideia de legalidade formal, para promover o controle de juridicidade. A LINDB passa a incluir o controle da avaliação apropriada de valores jurídicos abstratos e das consequências da decisão projetada, os quais devem compor, de modo expresso, a motivação da decisão, sob pena de nulidade. A existência e a veracidade desses motivos são sindicáveis pelos órgãos de controle, pelo Ministério Público e pelo Poder Judiciário.
Da responsabilidade civil do estado por omissão fiscalizatória: acidentalidade provocada pelo rompimento da barragem de Brumadinho
Authors: Faria Edimur Ferreira de , Souza Renata Martins
Published: April 2020

O presente artigo resulta de pesquisa que teve por objetivo investigar a possibilidade de responsabilização civil do Estado no caso do rompimento das barragens de rejeitos 1, 4 e 4A da Mineradora Vale S.A., na Mina do Feijão, no Município de Brumadinho/MG. O método utilizado foi o descritivo e exploratório. A hipótese proposta foi a de que a União e o Estado de Minas Gerais são, em tese, civilmente responsáveis solidariamente pelos danos causados, mas, que no caso em tela, a responsabilidade civil de ambos é subsidiária, considerando que a Vale reconheceu ser ela responsável pelos danos decorrentes do rompimento de suas barragens. A metodologia consistiu em pesquisa bibliográfica, jurisprudencial e a legislação pertinente. Após identificadas as causas, consequências e apontadas as falhas do responsável primário pela tragédia, examinou-se a teoria da responsabilidade civil do Estado, por danos extracontratuais, visando demonstrar que assim como a empresa mineradora exploradora de barragens, os entes federativos podem ser corresponsáveis pela ocorrência dos danos e pela reparação pecuniária às respectivas vítimas, se foram negligentes ao licenciar e fiscalizar a construção e operação das barragens. A conclusão é que a hipótese se confirmou.
Quem tem notável saber jurídico? O papel da Presidência da República e do Senado Federal no processo de nomeação dos ministros do Supremo Tribunal Federal na Constituição Federal de 1988

Published: April 2020

O presente artigo busca desvendar qual o papel exercido pela Presidência da República e pelo Senado Federal no processo de nomeação dos Ministros do Supremo Tribunal Federal. A partir do marco constitucional, o estudo busca desvendar quais os processos que se realizam na prática política brasileira que caracterizam o  modelo de escolha da mais alta cúpula judicial. Diante de que a Constituição de 88 orienta que são estes dois órgãos os responsáveis por indicar e nomear estas autoridades, é importante compreender como que o Supremo Tribunal Federal está sendo escolhido desde então, evidenciando o potencial uso de instrumentos de controle para que a decisão democrática possa adquirir a legitimidade devida e desejada. A partir de uma análise qualitativa e quantitativa, busca-se medir o comportamento político destes órgãos, de maneira a demonstrar as tendências de uso estratégico do poder para a escolha do Ministro do STF.
Democracia participativa na gestão pública eficiente da cidade
Authors: Casimiro Ligia Maria Silva Melo de , Machado Raquel Ramos
Published: April 2020

O artigo se propõe a ressaltar a importância do engajamento social na atividade de planejamento de políticas públicas urbanas, como forma de promoção de uma gestão democrática participativa das cidades. O processo de formação dos espaços urbanos reflete o perfil sociológico de uma determinada comunidade e a urbanização traz em si uma complexidade nas relações socioeconômicas, culturais e políticas que potencializam a inacessibilidade da cidadania pela ausência ou estrangulamento de bens e serviços urbanos, o que torna a cidade o local das violações e da negação da vida digna. Para dar resposta a tais problemas é preciso elaborar estratégias de ação que passam pelo planejamento democrático, tendo como referência proposições institucionais transformadoras capazes de estabelecer um canal formal que instrumentalize o diálogo com a população citadina, já que a mudança estrutural da cidade envolve também a mudança de comportamentos em que estão envolvidos todos que dela usufruem, desde o indivíduo, a iniciativa privada até o próprio poder público, gestor dos espaços urbanos.

Authors: Alves Felipe Dalenogare , Leal Mônia Clarissa Hennig
Published: April 2020

Este trabalho expõe o resultado de uma pesquisa bibliográfica, utilizando-se dos métodos fenomenológico-hermenêutico, para fins de abordagem, e histórico e monográfico, a título procedimental, sobre a temática da corrupção, tendo por objetivo principal realizar, além de uma investigação histórica acerca da corrupção no Brasil, uma análise dos principais instrumentos normativos de âmbito internacional e regional de prevenção e repressão ao fenômeno, os quais colaboram a uma proteção multinível dos direitos fundamentais. No decorrer do trabalho, buscou-se o esclarecimento de questões importantes à temática, como o seguinte problema: o ordenamento jurídico interno brasileiro tocante à matéria apresenta influência e compatibilização a esses instrumentos internacionais? Por fim, conclui-se que, mesmo que a multiplicidade dimensional que abarca o tema possa acarretar lacunas, é possível constatar que o Estado brasileiro, ainda que lentamente, normativamente, caminha no sentido de prevenir e reprimir os atos de corrupção, influenciado e compatibilizado aos instrumentos internacionais condizentes à matéria.

Cada vez mais ingressa no universo jurídico o tema políticas públicas, que se torna cada dia mais familiar e afeto a esse ramo da ciência. Do mesmo modo, tem-se aproximado muito do Direito referências à sustentabilidade, como objetivo a ser buscado também em sua seara, em vista do reconhecimento por grande parte da doutrina de seu caráter principiológico e, por isso irradiado amplamente em cada um de seus campos. Por essa razão, as contratações públicas passaram a exigir muito mais acurados processos de concepção, no que tange ao seu planejamento, tanto em vista da escassez de recursos públicos para fazer frente ao grande número de necessidades demandantes de ação estatal, como pela necessidade de identificação com os anseios da população. Em consonância com estas exigências o conjunto normativo tem recebido caráter de maior rigor quanto a observância desses limites, tendo se tornado o planejamento elemento crucial da atuação estatal, assumindo a exigência neste campo padrões semelhantes àqueles que se aplica no âmbito privado. O propósito neste artigo foi apresentar como tem sido percebido ambos os temas no Direito Brasileiro.

Objetivou-se avaliar a inclusão do resíduo de polpa de goiaba em dietas de codornas de corte sobre o desempenho produtivo, rendimento de carcaça, e viabilidade econômica, aos 42 dias de idade. Foram utilizadas 250 codornas europeias, não sexadas, de um dia de idade, distribuídas em delineamento experimental inteiramente casualizado com cinco níveis de inclusão (0,0; 3,0; 6,0; 9,0 e 12,0%) de resíduo de goiaba, com cinco repetições e 10 aves por unidade experimental. As variáveis avaliadas durante o período experimental foram: consumo de ração (CR), ganho de peso (GP) e conversão alimentar (CA), rendimento de carcaça, de cortes e visceras. Não foram observadas diferenças significativas (P>0,05) para o ganho de peso, o consumo de ração e conversão alimentar das aves durante o período de um a 42 dias de idade. Os pesos absolutos e os rendimentos de carcaça, cortes nobres (peito, coxa e sobrecoxa), vísceras comestíveis e gordura abdominal das aves não foram influenciados (P>0,05) pelos níveis de inclusão do resíduo de polpa de goiaba às dietas. O resíduo de polpa de goiaba pode ser utilizado como ingrediente alternativo nas dietas de codornas europeias, até o nível de 3% de inclusão, sem comprometer o desempenho produtivo, o rendimento de carcaça das aves e a viabilidade econômica.

Se diseñó un estudio para evaluar la idoneidad del jugo de sandía como diluyente del semen de conejo y la tasa de concepción conejos hembra inseminados. La sandía madura (Citrus lanatus) se obtuvo y procesó en jugo usando el procedimiento estándar. Para el ensayo se usaron un total de 10 conejo macho y 90 conejo hembra , todos de raza New Zealand White x Chinchilla. El semen se recolectó de los conejo macho utilizando una vagina artificial y se diluyó con jugo de sandía a una proporción 1: 0, 1: 0.25, 1: 0.67, 1: 1.5, 1: 4 o con solución salina normal 1:1; y se designó como T1, T2, T3, T4, T5 y T6 respectivamente. El análisis del semen se realizó en semen fresco y los diversos semen se diluyeron inmediatamente hasta 370C. Quince de cada uno fueron asignar al azar para el tratamiento diferente en un diseño completamente al azar y se inseminaron con su tratamiento respectivo utilizando el procedimiento estándar. La tasa de concepción, el tamaño de la camada y el índice de productividad al nacer se juzgado al final del período de gestación. El resultado obtenido reveló que el rango de valores obtenidos para la movilidad del espermatozoide, la integridad de la membrana estructural y la integridad del acrosoma está dentro de los valores aceptados para el semen de buena calidad. La tasa de concepción de inseminación con semen diluido con jugo de sandía a una proporción 1: 1.5 fue la tasa de dilución óptima con 75%. El tamaño de la camada fue significativamente (p

El uso masivo de pocos toros en programas de inseminación artificial afecta la composición y la estructura genética de una población. El objetivo de este estudio fue estimar la diversidad genética, estratificación genética, patrones de ancestría y el desequilibrio de ligamiento en ganado Simmental. Una muestra de 233 animales genotipados con 30106 marcadores tipo polimorfismo de nucleótido simple (SNP) fue usada. Los patrones de subdivisión genética y ancestría fueron estimados a través de análisis de componentes principales y probabilidades de asignación a grupos genéticos. El desequilibrio de ligamiento fue estimado como el cuadrado del coeficiente de correlación entre los SNP. El análisis por componentes principales no mostró patrones de subdivisión genética dentro de la población Simmental de Colombia. Sin embargo, el análisis de ancestría identificó una subdivisión genética de de tres grupos. Un valor de 0.3 para desequilibrio de ligamiento fue encontrado a una distancia de 33 kb. Los resultados permiten evidenciar el cambio en la estructura genética de una población debido al uso e importación de material genético proveniente de poblaciones que difieren en objetivos de cría y criterios de selección.

Objetivou-se realizar a análise exploratória dos resultados bromatológicos e uso de modelos para estimativa de nutrientes digestíveis totais de amostras de silagens de milho, por meio dos dados gerados a partir de 12 anos de análises comerciais do Laboratório de Nutrição Animal do Instituto de Zootecnia (IZ), em Nova Odessa, SP, Brasil. Como critério, utilizaram-se dados de amostras de silagens de milho sem nenhum tipo de aditivos, somando 220 amostras nos períodos de 2004 a 2015 e agrupados em quatro triênios. Estes foram caracterizados quanto à sua composição bromatológica através de análise estatística descritiva, correlações de Pearson e pela utilização de modelos de estimativas de NDT, utilizando-se quatro modelos de equações: uma da Universidade de Clemson, uma segundo Harlan e duas segundo Kearl (1 e 2). O valor nutricional das amostras de silagens de milho mostrou-se de qualidade mediana, com valores de FDN (49,2 a 57,2% da MS) acima do ideal de 37 a 45% da MS. Todas as equações puderam ser utilizadas na estimativa do NDT (variação de 54,3 a 67,0% nos triênios) sendo que a de Kearl 1 e Clemson apresentaram a maior e a menor variação entre os triênios, respectivamente. O aumento do valor nutritivo e de NDT nos triênios 3 e 4 indica melhoria na qualidade da silagem.

A avaliação do crescimento permite melhorar a compreensão da resposta da planta as condições de estresse. Objetivou-se avaliar a resposta do crescimento, acúmulo de biomassa e da eficiência do uso da água do sorgo a diferentes regimes hídricos continuados com água salina. O experimento foi conduzido em Serra Talhada, Pernambuco, Brasil. O sorgo, cv. Sudão IPA 4202, foi semeado em vasos em um viveiro. As plantas foram dispostas em delineamento inteiramente ao acaso submetidas a quatro regimes hídricos durante todo o ciclo com base na evapotranspiração de referência (ET0) (125%, 100%, 75% e 50%.ET0), com 32 repetições. Ao longo do tempo foram coletados dados de biometria, biomassa de forragem e consumo de água da cultura. A planta foi fracionada e seus componentes foram mensurados. Os índices morfofisiológicos foram obtidos. Não houve efeito de regime hídrico na maioria das variáveis de crescimento, acúmulo e partição de matéria seca. A eficiência do uso da água foi mantida, mesmo com a redução no consumo de água pela cultura. As mudanças no aparecimento e na senescência foliar não alteraram os índices morfofisiológicos, sugerindo manutenção da taxa fotossintética da cultura nas distintas disponibilidades de água. Conclui-se que, o sorgo, cv. Sudão IPA 4202, possui alta adaptação a ambientes de cultivo com ampla variação de regime hídrico, recomendando-se lâmina de 50%.ET0.

El género en la logística de la capacitación no ha recibido igual atención que otros aspectos del diseño de la capacitación a pesar de su importancia en el acceso a la información sobre innovaciones probadas y la aceptación por parte de los agricultores. El documento evaluó la preferencia de los agricultores porcinos y hembras por la logística de la capacitación, analizó la composición y el costo de la harina de yuca y los piensos comunes. Determinó los niveles de conciencia en las alimentaciones alternativas por género y discutió las limitaciones de capacitación de los agricultores. La técnica de muestreo intencional se utilizó para seleccionar dos estados y seis áreas de gobierno local en función de la preponderancia de los criadores de cerdos. El programa de entrevistas estructuradas se administró a 300 criadores de cerdos y a 18 informantes clave identificados mediante la técnica de muestreo de bolas de nieve. Los datos fueron sometidos a estadística descriptiva e inferencial. Los resultados incluyen las ventajas nutricionales y de costo de la harina de yuca, la mayoría de los encuestados en su edad activa, ambos sexos tuvieron un alto nivel de conciencia en alimentos alternativos y similitudes en las preferencias para los métodos de capacitación, el modo y el facilitador. Se diferencian en las preferencias para el lugar de entrenamiento, la duración, el día y la hora. Los resultados de ANOVA revelaron que las preferencias de los agricultores y las agricultoras por la logística de capacitación difieren significativamente (p

El estrés del destete puede alterar la salud intestinal de los cerdos; en esta etapa arginina se vuelve esencial ya que participa en la síntesis de poliaminas y éstas son importantes para mantener la viabilidad y proliferación celular en el epitelio intestinal. Se analizó la expresión de las enzimas arginino-succinato-sintasa (ASS) y espermina-espermidina-acetil-tranferasa (SSAT) relacionadas con la síntesis de arginina y poliaminas, en mucosa de intestino delgado de cerdos destetados. Veinticuatro cerdos destetados a los 28 días de edad, fueron sacrificados a los 0, 3, 7 y 14 días postdestete. Se colectaron muestras de mucosa de duodeno, yeyuno e íleon en las que se analizó la expresión relativa de ASS y SSAT. La expresión de ASS en duodeno se incrementó en el d3 (P
