Published: March 2019

Mercury is capable of atmospheric transfer by large distances, offers resistance to the environment, is able to bioaccumulation in ecosystems and leads to significant negative consequences for the public health. Aim: to study the mercury content in the hair of rural residents of the Yamalo-Nenets Autonomous District and assess the population health risks. Methods: A single-step epidemiological study was conducted with the formation of a representative selection of rural residents in the Yamal-Nenets Autonomous District. The hair samples were taken from the occipital part of the head using a standard WHO technique. Chemicoanalytical study of samples wwas carried out in a licensed laboratory using mass-spectrographic method with inductively coupled argon plasma. The statistical analysis was performed using the Statistica v.8.0 program. Differences were assessed as statistically significant at p < 0.05. Results: Mercury concentration in the hair of the inhabitants living in the rural settlements varied from 0.204gg/g to 9.99 gg/g and those leading the traditional (nomadic) lifestyle varied from 0.303 gg/g to 5.21 gg/g. Increased risk to public health of Tazovsky settlement was detected in 48.8 % of cases, for residents who led the traditional way of life in Gydansky, Antipayutinskaya and Nakhodka tundra - 86.6 %, Harsaim settlement - 77.3 %. Absolute average values of mercury content in hair of the aboriginal population were 2.6 times higher than in the migrants. Conclusions: It is necessary to strengthen control over mercury content in natural environments and its accumulation in food chains and to carry out measures to reduce the population health risk.

Authors: Nascimento Leidylene Porcina Alves , Bezerra Leonardo Mendes
Published: March 2019

O artigo objetivou analisar o estado da arte do curso de enfermagem partindo das produções monográficas de diversas especialidades, com foco nos procedimentos metodológicos utilizados para a elaboração das monografias do curso de Enfermagem do Centro de Estudos Superiores de Balsas, campus da Universidade Estadual do Maranhão. Com a conclusão de 06 (seis) turmas, e em conformidade com os preceitos do Ministério da Educação, o Projeto Pedagógico do referido curso dispõe acerca da exigência de elaboração de uma monografia como trabalho de conclusão de curso. A partir das experiências vivenciadas e de diálogos com egressos, despertou-se a curiosidade em conhecer os procedimentos metodológicos utilizados para a elaboração do trabalho em questão. Hipoteticamente, o que se percebe é que a metodologia aplicada na forma de compreender a dimensão da pesquisa não fora absorvida satisfatoriamente pelos concluintes. Diante disso, para alcançar os objetivos deste estudo, utilizamos como fonte a pesquisa bibliográfica, documental, quantitativa, com a utilização de recursos da estatística descritiva e qualitativa no tocante à análise de conteúdo, proposto por Bardin. Foi realizada a leitura de 125 (cento e vinte e cinco) monografias, o que corresponde a uma amostra de 69,83%. Os resultados apontaram que as pesquisas realizadas na elaboração das monografias dos egressos tiveram uma diversidade de métodos, técnicas, procedimentos, público investigado, locais da pesquisa, mas a pesquisa quantitativa é a mais recorrente. A priori, recomenda-se que a monografia seja inserida no sexto período do curso, por fazer parte de um processo na construção de saberes. Ademais, é salutar que este estudo seja utilizado por outras turmas na universidade e em outras instituições de ensino superior, para identificar as tendências pesquisadas na área da enfermagem, assim como expor facilidades e dificuldades na elaboração das monografias.

Frente aos desafios que a disciplina de Matemática e seu Ensino apresentam e, entendendo o processo de ensino e aprendizagem como uma interação social, este artigo busca olhares acerca do saber matemático, sob a ótica da Teoria das Representações Sociais tendo como objetivo compreender quais representações, socialmente construídas e compartilhadas por alunos e professores acerca da Matemática e seu Ensino conformam o processo de ensino e aprendizagem dos conceitos matemáticos no âmbito da prática docente. Delineamos o presente trabalho na identificação da Matemática e seu Ensino como objetos representacionais para os grupos sociais que participam da pesquisa por meio da aplicação de questionários e com auxílio do software EVOC. Os resultados apontam que a matemática e seu ensino são representacionais e tem relevancia para este grupo social tanto no aspecto social, quanto no cognitivo e afetivo. As conclusões indicam que para um efetivo ensino da Matemática não basta apenas modificar as ações didáticas se mantivermos as mesmas representações sociais.

Published: March 2019

No estado do Espírito Santo o censo do INEP de 2015 informa que a cada 20 escolas, apenas 3 possuem laboratório de ciências. A falta de contato dos alunos com as aplicações das ciências que estudam nos livros reflete-se nos exames (nacionais e internacionais) que avaliam o desempenho dos alunos nessa área. Um projeto que aproxime os alunos das escolas públicas aos alunos da Universidade Federal do Espírito Santo com o objetivo de cultivar microalgas – indo desde a construção de um foto biorreator com materiais recicláveis até a extração do óleo da microalga –, pode mudar essa realidade. Revisando os estudos sobre microalgas já desenvolvidas no Laboratório de Engenharia do Trabalho e no Laboratório de Operações Unitárias do Centro Universitário Norte do Espírito Santo (CEUNES) entre os anos de 2012 e 2014, os benefícios e desafios para implementar tal projeto foram identificados.

Published: March 2019

A fim de encontrar maneiras sustentáveis de destinar os resíduos orgânicos, busca-se atualmente utilizar-se de processos biológicos para tratamento, sendo possível utilizar seus derivados como fonte de energia e adubo. O artigo tem como objetivo analisar os dados de uma pesquisa a qual avaliou o potencial energético do biogás produzido a partir da biodigestão anaeróbia do resíduo alimentar produzido pelo restaurante Sem Nome no município de Itajubá – MG. Foi construído um projeto piloto, constituído por três garrafas PET´s, as quais serviram como reatores, além de outros objetos como válvula de gás, mangueira de alta pressão e controle de temperatura. Foi monitorado a produção de CH4, CO, CO2, O2, H2S, Temperatura e Pressão, além da realização de análises físicas e químicas as quais avaliaram os parâmetros como ST, STF, SV, DBO, DQO e pH. A concentração de CH4 no biogás, assim como o potencial energético, foram estimados teoricamente, devido a falhas no sistema de biodigestão como quedas constantes de temperatura e presença de rupturas nos reatores, causando infiltração de gás atmosférico. Portando, considerando condições favoráveis para realização da biodigestão anaeróbia, e com base em dados fornecidos pela literatura, estimou-se a produção de CH4, assim como o potencial energético do restaurante, conferindo 65,65 L/dia de CH4 durante a semana e 87,54 L/dia nos fins de semanas e feriados, disponibilizando mensalmente 6.569,86 kWh de energia. Com esses dados, foi possível confirmar a eficiência da metanização como um sistema sustentável de destinação dos resíduos orgânicos, além de auxiliar na geração de energia elétrica.

O monitoramento das temperaturas é uma conduta indispensável para se garantir a inocuidade do alimento, devendo ser observado como forma de prevenir a multiplicação microbiana, precisando ser constantemente executado. O presente estudo teve por objetivo avaliar a temperatura das preparações do almoço de uma Unidade de Alimentação e Nutrição de uma Instituição Federal de Ensino, conforme legislação vigente. Foram aferidas as temperaturas de 43 preparações quentes e 12 preparações frias, durante 12 dias, no horário do almoço: início, meio e final da distribuição. As temperaturas de preparações como arroz/feijão apresentaram concordância de 100 % com os valores preconizados pela a legislação vigente. Já as preparações como guarnições e saladas, apresentaram discordância em suas temperaturas, com um índice de adequação de 0% a 66,7%. Os registros das temperaturas e o preenchimento adequado de impressos são uteis para monitoramento e controle da qualidade das preparações servidas, impulsionando a adoção de medidas que auxiliem na conservação das temperaturas dentro do intervalo preconizado. Considerando a Unidade de Alimentação e Nutrição avaliada, a aquisição de um balcão térmico para preparações frias seria uma medida de correção necessária a ser implementada.

Structural analysis of seasonal dynamics of daily growth of annual shoots of woolly-stemmed willow
Authors: Afonin A. , Vikhrova I.
Published: March 2019

Given the complex characteristics of woolly–stemmed willow. The necessity of studying the regularities of seasonal dynamics of daily growth of annual shoots is substantiated. The study used material from the model inbred-clone population. Empirical data were processed using structural–harmonic analysis methods. It was found that the seasonal dynamics of the daily growth of shoots is cyclic quasi–periodic. Empirical series of dynamics at the highest level of significance are approximated by sums of elementary harmonics with a period of oscillation of 9.2 to 92.0 days. Revealed high-amplitude harmonic with the oscillation period of 23.0 to 92.0 day and low amplitude with a period of oscillation of 9.2 to 18.4 days. On all the studied shoots only the fourth harmonics coincide with the oscillation period of 23.0 days. The main contribution to the seasonal dynamics of shoot growth is made by three high-amplitude harmonics, which form two main signals with oscillation periods of 23 and 36 days. Other harmonics have a modulating effect on the seasonal dynamics of shoot growth. The first harmonics with a period of oscillation 92.0 days determine the nonlinearity of the seasonal trend of growth of shoots. Higher harmonics with a period of oscillation of 9.2 to 15.3 days form the resulting quasi–cyclic oscillation. Significant interclonal and intraclonal differences in the rhythm of daily growth of annual shoots were not revealed. On this basis, the proposed recommendations for agroforestry–technical events in the plantings of woolly–stemmed willow.

Engelliliğin çoğu formunun insanlarda sedanter yaşam
stiline sebep olmasına rağmen engelli bireyler için düzenli fiziksel
aktiviteden spor yapmaya kadar değişen fırsatlar mevcuttur. Geçtiğimiz yüzyılda
engelli bireylerde spor, medikal rehabilitasyon modelinden yarış sporları
modeline dönüşmüştür. Engelli sporcuların adil rekabetini sağlamak için
sporcuların hareketlerine dayanan fonksiyonel bir sınıflandırma sistemi
kullanılmaktadır. Sporcular rekabet için 1’ den 6’ya kadar engelli kategorisine
ayrılmıştır. Bu kategoriler tekerlekli sandalye atletleri, ampute atletler,
serebral palsili atletler, görme engelli atletler, mental bozukluğu olan
atletler ve diğerleri şeklindedir. Spora katılım beraberinde yaralanma riskinde
artışı da getirmektedir.  Her kategoride
engelliliğin durumuna göre farklı spor yaralanmaları görülür. Spor
yaralanmalarını önlemede ilk basamak yaralanma sıklığının ve derecesinin
belirlemesi, ikinci basamak yaralanma risk faktörleri ve mekanizmalarının
belirlenmesi olarak belirtilmiştir. Literatürde mevcut çalışmalar yaralanma
tanımı konusunda eksiktir. Çalışmalar arasında popülasyon ve metodoloji
konularında önemli farklar vardır. Bazı çalışmalar spor ve yaralanma odaklı,
bazıları ise yaralanma odaklı çalışmalardır. Bu da yaralanma ve spora bağlı

Metas de inflação e consistência expectacional em um modelo com regra de juros não linear
Authors: Iwai Drumond Carlos Eduardo , De Jesus Cleiton Silva , Pereima João Basilio
Published: March 2019

The aim of this paper is to develop a post-Keynesian macroeconomic model that takes into account a non-linearity in the interest rate rule. We assume that the monetary authority considers, in the practice of monetary policy, an interaction between inflation rates and the rate of capacity utilization, so that the sensitivity of the interest rate rule to the gap of inflation in relation to target varies according to the economic cycle. The macroeconomic policy framework proposed here allows the monetary authority to be sensitive to the inflation and to the output without, losing sight of the anchoring role of the inflation target.

The aim of this paper is twofold. At first, we briefly review the current debate in Brazil between the new-developmentalists and the social-developmentalists. Both groups assume that the investment is the main component of aggregate demand to explain growth. However, the key variable to determine demand for investment is different for each group. For the new-developmentalists, the key variable is the real exchange rate. For the second group, public investment and domestic mass consumption are the most relevant variables. Given this debate, our next step is to test econometric models that capture the determinants of investment in Brazil in the 2000s. We start with the investment function presented by Bhaduri and Marglin (1990) and add other variables according to the developmentalist debate. We found robust results that confirm the validity of Bhaduri and Marglin´s hypothesis as well as the ones proposed by the new-developmentalists and the social-developmentalists.
Liquidity Trap: the Brazilian version
Authors: Ferrari Filho Fernando , Milan Marcelo
Published: March 2019

The goal of this paper is to provide an interpretation about the sky-high real interest rates in Brazil. We use Keynes’ argument regarding liquidity trap to identify the forces trapping interest rates, but in Brazil they are trapped at very high levels instead of at the zero-lower bound discussed in Keynes’s General Theory. Rentiers, in Brazil, influence the Brazilian Central Bank to obtain very liquid assets in the form of Financial Treasury Bills (LFTs) while keeping high interest earnings. In this case expansionary fiscal policies will have a limited impact on output, given the resulting high debt levels and debt service, but will imply significant income transfers to the rentiers. This means that aggregate demand and income will be less sensitive to fiscal stimuli, but the distribution of income will be biased toward the rentiers. 

 
THE LEGALITY OF HUMANITARIAN INTERVENTION: THE CASES OF KOSOVO AND LIBYA
Authors: Erendor Mehmet E.
Published: March 2019

Humanitarian intervention is the one of the most critical concepts with respect to legality and legitimacy. Although, there is no common definitions, theorists or international community defines it as violations of human rights. The main aim of this study is to argue that the international community has the responsibility to intervene to prevent a humanitarian crisis. This research also attempts to clarify the legality and legitimacy of humanitarian interventions which are limited to cases of threats to international peace, security and where there exists prior authorization by the UNSC. The article argues that humanitarian interventions should only be established under the authorization of the UNSC; and that when violation of human rights is interpreted as a threat to international peace and security, if an intervention has been authorized by the SC, it is legal.
THE WESTERN RUSSOPHOBIC PARANOIA AFTER THE COLD WAR AND GLOBAL SECURITY

In regard to international relations (IR), power is understood as the ability of state or other political actors to impose its own control or influence over other state(s) or other political actors, or at least to influence the outcome of events on the local, regional or global level. Power politics as a phenomena has two dimensions: internal and external. The internal dimension is applied in the inner policy of the state and the external in the foreign affairs or outside of the home politics. The powerfulness of a state depends on its real independence or sovereignty from outside influence on both formulation and realization of its own policy. The internal power is represented by the level of autonomy in the inner affairs while the external power corresponds to capacity to control the behaviour and influence from the outside in domestic affairs and to influence by itself the affairs and politics of the others. However, a majority of researchers suggest that power politics mostly means the potential capacity and practical ability to influence the behaviour of other actors in IR in accordance with its own aims calculated into the framework of public or secret national interests.

Antecedentes: Los estudios sobre la micobiota asociada a insectos plaga comúnmente se enfocan sólo a especies entomopatógenas para su uso en control biológico, sin considerar muchas otras que podrían estar involucrados en las enfermedades de las plantas de cultivo de interés.Objetivos: Analizar la micobiota asociada a cadáveres de insectos plaga de maíz en el estado de Querétaro para conocer el impacto que tienen en los sistemas agrícolas.Métodos: La identificación de las cepas aisladas de los insectos plaga se realizó mediante taxonomía clásica y un análisis filogenético de las secuencias de la región ITS1, 5.8S e ITS2 del ADNr.Resultados y conclusiones: Se aislaron 18 cepas de hongos asociados a cadáveres de insectos catalogados como plagas de importancia económica en el estado de Querétaro. Los aislados pertenecen a los géneros Fusarium, Beauveria, y Purpureocillium aisladas de Melanoplus sp., Toxoptera citricida y larvas de Spodoptera frugiperda como hospederos. La presencia de especies del género Fusarium presentó una alta prevalencia en el muestreo, seguido por B. bassiana y P. lilacinum sugiriendo que pueden estar actuando en el control de plagas de forma natural, pero también los insectos plaga pueden actuar como vectores de algunas especies de hongos fitopatógenos entre los cultivos.

The fertile stroma in pancreatic ductal adenocarcinomas (PDACs) has been suspected to greatly contribute to PDAC progression. Since the main cell constituents of the stroma are fibroblasts, there is crosstalking(s) between PDAC cells and surrounding fibroblasts in the stroma, which
induces a fibroblast proliferation burst. We have reported that several malignant cancer cells including PDAC cells secrete a pronounced level of S100A11, which in turn stimulates proliferation of cancer cells via the receptor for advanced glycation end products (RAGE) in an autocrine manner.
Owing to the RAGE+ expression in fibroblasts, the extracellular abundant S100A11 will affect adjacent fibroblasts. In this study, we investigated the significance of the paracrine axis of S100A11‐RAGE in fibroblasts for their proliferation activity. In in vitro settings,
extracellular S100A11 induced upregulation of fibroblast proliferation. Our mechanistic studies revealed that the induction is through RAGE‐MyD88‐mTOR‐p70 S6 kinase upon S100A11 stimulation. The paracrine effect on fibroblasts is linked mainly to triggering growth but
not cellular motility. Thus, the identified pathway might become a potential therapeutic target to suppress PDAC progression through preventing PDAC-associated fibroblast proliferation.
Ultra-luminous X-Ray Sources as Super-critical Propellers

We study the evolution of newborn neutron stars in high-mass X-ray binaries interacting with a wind-fed super-Eddington disk. The inner disk is regularized to a radiation-dominated quasi-spherical configuration for which we calculate the inner radius of the disk, the total luminosity of the system and the torque acting on the neutron star accordingly, following the evolution of the system through the ejector and early propeller stages. We find that the systems with B ≳ 1013 G pass through a short (∼20 yr) ejector stage appearing as supernova impostors followed by a propeller stage lasting ∼103 yr. In the super-critical propeller stage the system is still bright (L ∼ 1040 erg s−1) due to the spindown power and therefore appears as an ultra-luminous X-ray source (ULX). The system evolves into pulsating ULX (PULX) when the neutron star spins down to a period (P ∼ 1 s) allowing for accretion onto its surface to commence. Systems with lower magnetic fields, B ∼ 1011 G, pass through a long (105 yr) super-critical propeller stage with luminosities similar to those of the ultra-luminous super-soft sources (ULS), L ≲ 1040 erg s−1. The equilibrium periods of these systems in the accretion stage is about 10 ms, which is much smaller than the typical period range of PULX observed to date. Such systems could have a larger population, but their pulsations would be elusive due to the smaller size of the magnetosphere. Our results suggest that the ULS and some nonpulsating ULX are rapidly spinning and highly magnetized young neutron stars at the super-critical propeller stage.

Published: March 2019

We report the study of an “Einstein Cross” configuration first identified in a set of HST images by Cerny et al. Deep spectroscopic observations obtained at the Spanish 10.4 m Gran Telescopio Canarias telescope, allowed us to demonstrate the lens nature of the system, that consists of a Lyman-break galaxy (LBG), not a quasi-stellar object as is usually the case, at z = 3.03 lensed by a galaxy at z = 0.556. Combining the new spectroscopy with the archival HST data, it turns out that the lens is an elliptical galaxy with M

V
 = −21.0, effective radius 2.8 kpc, and stellar velocity dispersion σ = 208 ± 39 km s−1. The source is an LBG with Lyα luminosity ∼L* at that redshift. From the modeling of the system, performed by assuming a singular isothermal ellipsoid (SIE) with external shear, we estimate that the flux source is magnified about 4.5 times, and the velocity dispersion of the lens is

km s−1, in good agreement with the value derived spectroscopically. This is the second case known of an Einstein cross of an LBG.
Inspiral of a Spinning Black Hole–Magnetized Neutron Star Binary: Increasing Charge and Electromagnetic Emission
Authors: Dai Z. G.
Published: March 2019

The mergers of black hole (BH)–neutron star (NS) binaries have been one of the most interesting topics in astrophysics, because such events have been thought to possibly produce multimessenger signals including gravitational waves and broadband electromagnetic (EM) waves. In this paper, we investigate EM emission from the inspiral of a binary composed of a spinning BH and a magnetized NS. Observationally, the BH is usually more massive than ∼7 M
⊙ and the NS has a mass ≃1.4 M
⊙. During the inspiral of such a binary, the BH will accumulate more and more charges based on the charging scenario of Wald, even though the BH will eventually swallow the NS whole inevitably. We calculate the emission luminosities and energies through three energy dissipation mechanisms: magnetic dipole radiation, electric dipole radiation, and magnetic reconnection. We show that magnetic dipole radiation due to the spin of the increasingly charged BH and magnetic reconnection in between the BH and the NS could be most significant at the final inspiral stage. We find that if the BH is rapidly spinning and the NS is strongly magnetized, these mechanisms would lead to a detectable EM signal (e.g., a short-duration X-ray transient).
