Ocorrência da infecção pelo vírus da artrite encefalite Caprina em Patos de Minas, Minas Gerais, Brasil.

Com o objetivo de investigar a ocorrência da artrite encefalite caprina (CAE) em um capril leiteiro no município de Patos de Minas (MG), colheram-se amostras de sangue de 57 caprinos de idades variadas, ambos os sexos e sem raça definida. Realizou-se um questionário epidemiológico abordando os dados da propriedade, como os tipos de intalações e os manejos sanitário, alimentar e reprodutivo. As amostras foram encaminhadas para o Laboratório de Virologia da Embrapa Caprinos e Ovinos, Sobral (CE), onde se realizou o teste de imunodifusão em gel de ágar (IDGA) para a detecção de anticorpos anti-CAEV. A freqüência de anticorpos anti-CAEV em uma propriedade no município de Patos de Minas (MG) foi de 22,80% (13/57). O manejo incorreto favoreceu a ocorrência da CAE nesta propriedade. A presença de anticorpos anti-CAEV é um alerta para a necessidade de adoção de medidas preventivas, evitando a sua disseminação para outras propriedades e regiões

Analysis of Respiratory Tract Cancer: A Population-Based Study

Cancer is one of the main causes of mortality in Brazil and in the world. Respiratory cancer is one of the most expressive fractions. It is important to study its incidence and try to correlate its association with behavioral factors in big urban centers such as the ABC region in Sao Paulo. This paper focuses on analyzing and comparing the incidence of respiratory tract cancers in the population of the ABC region and their respective correlations with the state of Sao Paulo and Southeast region. This is an ecological observational study with temporal analysis, using secondary data referring to hospital admissions for cancer of the larynx, trachea, and lung in the ABC region from 2008 to 2017. In the ABC region, the female sex showed a greater increase in older age groups. Sao Paulo showed a significant increase for both genders in the age group over 60 years old. Southeast region showed the greatest significant variation, with the male gender decreasing in the younger age groups and increasing in the older age groups, while the female is increasing in older age groups. Airway cancers in the younger age groups for both males and females are decreasing in all regions analyzed. For older age groups, numbers are increasing especially in the ABC region. The most important correlation found in this study is an increase in the number of cases of these diseases in women compared to men, which may suggest that females have increased their tobacco consumption, while men appear to be decreasing

Diet of four lizards from an urban forest in an area of amazonian biome, eastern amazon

This study described the diet and niche overlap of four lizards from an urban fragment in Amapá state. The samplings were performed through pitfall traps and active visual search. In the stomach analysis, Formicidae and Coleoptera represented 50.79% of the total items. The highest niche overlap value was between Gonatodes humeralis and Tropidurus hispidus, which was not expected due to habitat use. The foraging strategies of all lizards observed have been previously mentioned by several authors. Several studies cite the diet of lizards being basically composed of invertebrates, with few variations, as also demonstrated in this study.Este estudio describió la dieta y la superposición de nicho de cuatro lagartos de un fragmento urbano en el estado de Amapá. Los muestreos se realizaron a través de trampas y búsqueda visual activa. En el análisis estomacal, Formicidae y Coleoptera representaron el 50.79% del total de ítems. El valor de superposición de nicho más alto fue entre Gonatodes humeralis y Tropidurus hispidus, que no se esperaba debido a la diferencia en el uso del hábitat. La estrategia de alimentación de todos los lagartos observados ha sido mencionada anteriormente por varios autores. Varios estudios indican que la dieta de los lagartos se compone básicamente de invertebrados, con pocas variaciones, como también se demostró en este estudio.Asociación Herpetológica Argentin

Uma análise das seleções da Copa do Mundo de Futebol 2018 utilizando uma rede de transferências de jogadores entre países

O futebol é o esporte mais popular do mundo. O crescimento no número de transações de compra e venda de jogadores, \textit{marketing}, patrocínios, venda de ingressos, contratos de TV, entre outras formas de monetização do futebol faz com que o fluxo de valores seja cada vez maior. Grande parte dos trabalhos relacionados a esse esporte são associados a análises sociológicas. Neste trabalho, é proposto um estudo focado nas transações feitas entre as seleções classificadas para a Copa do Mundo 2018 utilizando técnicas de redes complexas para uma análise da transferência de jogadores entre esses países

The BLue Amazon Brain (BLAB): A Modular Architecture of Services about the Brazilian Maritime Territory

We describe the first steps in the development of an artificial agent focused on the Brazilian maritime territory, a large region within the South Atlantic also known as the Blue Amazon. The "BLue Amazon Brain" (BLAB) integrates a number of services aimed at disseminating information about this region and its importance, functioning as a tool for environmental awareness. The main service provided by BLAB is a conversational facility that deals with complex questions about the Blue Amazon, called BLAB-Chat; its central component is a controller that manages several task-oriented natural language processing modules (e.g., question answering and summarizer systems). These modules have access to an internal data lake as well as to third-party databases. A news reporter (BLAB-Reporter) and a purposely-developed wiki (BLAB-Wiki) are also part of the BLAB service architecture. In this paper, we describe our current version of BLAB's architecture (interface, backend, web services, NLP modules, and resources) and comment on the challenges we have faced so far, such as the lack of training data and the scattered state of domain information. Solving these issues presents a considerable challenge in the development of artificial intelligence for technical domains

Herpetofauna of an urban environmental protection area in an Amazon forest remnant of Amapá state, northern Brazil

The herpetofauna of Amazonia biome is one of the richest in the world. However, there is a lack of information on its richness and distribution. Here we provide a list of the herpetofauna from the Environmental Protection Area of Lagoa dos Índios, state of Amapá, Brazil, in the northern Amazon Forest. Sampling effort was conducted by active search in three distinct transects from January to May 2018 (rainy season) and August to December 2019 (drought season). We recorded 46 species composing the local herpetofauna, being 18 amphibians and 28 reptiles. Scinax ruber, Gonatodes humeralis and Helicops angulatus were the most abundant species. Regarding the conservation status, two species are categorized as Date Data deficient, (Lysapsus bolivianus and Eunectes deschauenseei), and one as Vulnerable (Podocnemis unifilis) in the Red List of the International Union for Conservation of Nature. Podocnemis unifilis is also considered Near Threatened in the Brazilian Red List of Endangered Species. Our results suggest that local biodiversity is still underestimated and, if expanded, could increase the species richness in the area. This study represents preliminary trends and raise further questions concerning the herpetofauna assemblage of Eastern Brazilian Amazonia.El bioma de la herpetofauna de la Amazonia es uno de los más ricos del mundo. Sin embargo, falta información sobre su riqueza y distribución. Aquí proporcionamos una lista de la herpetofauna del Área de Protección Ambiental de Lagoa dos Índios, estado de Amapá, Brasil, en el norte de la Selva Amazónica. El esfuerzo de muestreo se realizó mediante búsqueda activa en tres transectos distintos de enero a mayo de 2018 (temporada de lluvias) y de agosto a diciembre de 2019 (temporada de sequía). Registramos 46 especies que componen la herpetofauna local, siendo 18 anfibios y 28 reptiles. Scinax ruber, Gonatodes humeralis y Helicops angulatus fueron las especies más abundantes. En cuanto al estado de conservación, dos especies están categorizadas como Datos deficientes en fecha, (Lysapsus bolivianus y Eunectes deschauenseei), y una como Vulnerable (Podocnemis unifilis) en la Lista Roja de la Unión Internacional para la Conservación de la Naturaleza. Podocnemis unifilis también se considera Casi Amenazada en la Lista Roja Brasileña de Especies Amenazadas. Nuestros resultados sugieren que la biodiversidad local todavía se subestima y, si se amplía, podría aumentar la riqueza de especies en el área. Este estudio representa tendencias preliminares y plantea más preguntas sobre el conjunto de herpetofauna de la Amazonia brasileña oriental.Asociación Herpetológica Argentin

Hydrostatic Pressure Sensing with High Birefringence Photonic Crystal Fibers

The effect of hydrostatic pressure on the waveguiding properties of high birefringence photonic crystal fibers (HiBi PCF) is evaluated both numerically and experimentally. A fiber design presenting form birefringence induced by two enlarged holes in the innermost ring defining the fiber core is investigated. Numerical results show that modal sensitivity to the applied pressure depends on the diameters of the holes, and can be tailored by independently varying the sizes of the large or small holes. Numerical and experimental results are compared showing excellent agreement. A hydrostatic pressure sensor is proposed and demonstrated using an in-fiber modal interferometer where the two orthogonally polarized modes of a HiBi PCF generate fringes over the optical spectrum of a broad band source. From the analysis of experimental results, it is concluded that, in principle, an operating limit of 92 MPa in pressure could be achieved with 0.0003% of full scale resolution
