Range limitation of the Peaks of Otter salamander (Plethodon
hubrichti) due to competition with the eastern red-backed
salamander (Plethodon cinereus) in sympatry
Authors: Brophy Timothy R.
Published: July 2020

The Peaks of Otter salamander, Plethodon hubrichti, is a montane species found at altitudes above 442 m within a 117 km2 area of the Blue Ridge Mountains in central Virginia, USA. In areas where this species is sympatric with the eastern red-backed salamander (Plethodon cinereus) it seemed likely that P. hubrichti populations were either depressed or eliminated.
The habitability of areas beyond the current range boundaries for P. hubrichti is supported by several disjunct populations in areas sympatric with P. cinereus. From 2009 to 2012 we tested whether P. hubrichti was negatively impacted by competition with P. cinereus by removing P. cinereus from treatment plots at three sympatric field locations. The number of surface-active (SA) P. hubrichti increased significantly more on treatment plots than on corresponding reference plots, whereas the number of SA P. cinereus decreased significantly more on treatment plots than on reference plots. The removal of every one P. cinereus from the treatment plots led to an increase of 0.69 P. hubrichti. These results emphasise the importance of conserving mature hardwood forests along the perimeter of the P. hubrichti distribution, where it is sympatric with P. cinereus, so as to prevent future range contraction of this vulnerable species.
Cannibalism in smooth snakes, Coronella austriaca
Authors: Jofré Gabriela M.
Published: July 2020

Cannibalism is a widespread behavioural trait in nature and snakes are no exception. In smooth snakes (Coronella austriaca) it has only been visibly observed in captive individuals or known from faecal/stomach content
analyses. Between 2009 and 2018 one incidence of cannibalism, determined from a faecal sample, and one sighting, were recorded in wild smooth snakes in Wareham Forest plantations, UK. Analysis of faecal samples and visual encounter surveys were used to estimate its frequency.
Both records occurred in early autumn and our results suggest that its incidence in wild smooth snakes in southern England is low (0.1-0.3 %) and may be the result of low body condition. The circumstances resulting in cannibalism in the smooth snake may also be relevant to other animal species where cannibalism has been reported.

Durante el Trienio Constitucional (1820-1823) se redactaron diversos proyectos constitucionales (tanto exaltados como moderados) para mostrar una alternativa política a la Constitución de Cádiz. Una parte esencial de esos proyectos residía en el diseño de un Parlamento diferente del que se incluía en la Constitución de 1812. Los proyectos exaltados optaron por incrementar los poderes del Parlamento, apuntando hacia un gobierno asambleario influido por el pensamiento político revolucionario. Por su parte, los pensadores moderados se inclinaron principalmente por un Parlamento que debería ser una pieza clave para imitar la Constitución equilibrada de Inglaterra, lo que exigía tanto disminuir sus poderes como dividirlo en dos cámaras.
El confuso mundo de las habilitaciones reglamentarias

Published: July 2020

El trabajo analiza la práctica de las disposiciones finales de las leyes que contienen habilitaciones para su desarrollo reglamentario. Examina sus múltiples variantes, las dudas que suscitan desde la perspectiva de las autoridades facultadas para llevar a cabo el desarrollo reglamentario y de sus requisitos, así como la posibilidad de considerar existente la obligación jurídica de llevar a cabo estas tareas y de su exigencia en vía judicial, a la luz de los últimos avances jurisprudenciales.
Internet y política: consecuencias políticas y sociales de la revolución digital
Authors: Barberá Pablo
Published: July 2020

El éxito de internet como nueva plataforma comunicativa ha generado una profunda transformación política y social. El objetivo de este artículo es ofrecer un análisis de estas consecuencias, utilizando como hilo conductor la principal transformación que conlleva la revolución digital: una reducción radical en los costes de entrada a la comunicación de masas. En contraste con el optimismo inicial sobre la democratización de la esfera política en la era de internet, y la actual preocupación sobre los efectos negativos de las redes sociales, mi argumento es que estas consecuencias no son universalmente positivas o negativas. En mi análisis, me centro en tres aspectos centrales de la revolución digital: la posible polarización resultante del consumo social de información política a través de internet, el uso de herramientas tecnológicas para la coordinación de movimientos sociales y los efectos del uso de redes sociales en la calidad de la democracia representativa y las políticas públicas.

Las leyes ómnibus no quiebran per se el principio de seguridad jurídica. Inconstitucionalidad indirecta por contravención de normativa estatal básica
Authors: Ripollés Serrano María Rosa
Published: July 2020

En la sentencia se afirma que las denominadas “leyes ómnibus”, que según el recurso podrían ser causa de inseguridad jurídica e incluso de arbitrariedad de las autoridades públicas, ambos principios prohibidos en el artículo 9.3 de la Constitución Española, podrían considerarse como una técnica legislativa errónea pero no inconstitucional, ya que no están expresamente prohibidas por ninguna disposición constitucional. Por otra parte, el fallo ha determinado que hay algunas cláusulas impugnadas que son inconstitucionales debido a inconstitucionalidad indirecta por contravenir leyes básicas del Estado.

Introdução: Biomateriais são materiais sintéticos ou naturais que têm por objetivo substituir e/ou tratar algum componente do organismo. Dentre os diversos tipos de biomaterias, o de maior sucesso relatado na literatura é o de origem autógena, porém há a desvantagem de se criar uma segunda ferida cirúrgica para sua extração. Uns dos desafios na área médica-odontológica atual é a regeneração óssea por meios de biomateriais que não sejam de origem autógena. Neste contexto, o uso de biopolímeros como a quitosana extraída da quitina de carapaças de crustáceos vem sendo estudada como uma alternativa para terapias de regeneração óssea. Objetivo: Verificar a presença na literatura sobre o potencial de regeneração óssea in vivo da quitosana, em periódicos nacionais e internacionais. Materiais e métodos: Busca de informações nas bases de dados PubMed, Lilacs, Scielo, Periódicos Capes e Google Acadêmico no período de 2009 a 2019. Resultado: Nesse contexto, foi encontrado em sua maioria resultados positivos para regeneração óssea ou potencial para cicatrização óssea de estruturas de quitosana isoladas ou associadas. Conclusão: Conclui-se que o uso da quitosana no reparo ósseo apresenta-se como uma terapia promissora.

The diversity of whole rice grains with black and red pericarp has been valued in Brazil due to its different characteristics of color, texture, and also due to the association with health benefits. This work aimed to evaluate the physicochemical, cooking, and textural characteristics of different samples of polished and whole rice grains from different varieties marketed in Brazil. A total of 28 samples were collected and divided into 6 groups: polished white rice, white polished parboiled rice, whole white rice, whole red rice, whole black rice, and whole wild rice.  Moisture content, crude protein, ash, mineral content, hardness, and adhesiveness were analyzed. The cooking quality was evaluated through the determination of cooking time, swelling ratio, and volume expansion ratio. A strong correlation between the protein content and the hardness value of cooked grains was observed. The polished samples showed the lowest ash and mineral values and the shortest cooking time. A strong correlation was also observed for the volume expansion ratio and hardness of cooked samples. The data obtained contribute to a better understanding of the quality of the rice marketed in Brazil and demonstrate a large variation among samples in terms of physicochemical, cooking, and texture properties.

Objetivou-se verificar o perfil socioeconômico dos profissionais lagosteiros e a percepção destes em relação ao sistema pesqueiro “lagosta” na costa norte do Brasil. Foram entrevistados 40 profissionais, entre armadores, mestres e pescadores residentes nos municípios de Augusto Corrêa e Bragança (Pará), por meio da técnica “Bola de Neve”, entre setembro/14 e dezembro/15. Uma lista de 41 atributos, na forma de variáveis categóricas, foi elaborada para caracterizar o sistema pesqueiro “lagosta”. Os entrevistados eram do sexo masculino, com idade entre 21 e 60 anos. Desses, 62,5% nasceram no estado do Ceará e possuem baixo nível de escolaridade (60%). A renda dos entrevistados variou de R$ 800,00 a R$ 19.000,00/viagem, refletindo nas boas condições básicas de moradia e saúde, exceto para alguns pescadores. Acidentes de trabalho foram relados por mestres (20%) e pescadores (15%) durante as pescarias. A partir da percepção dos entrevistados, foi elencado padrões particulares para o sistema pesqueiro “lagosta”. Em geral, destacaram-se as dimensões social, econômico e ambiental, indicando a importância dessa atividade na manutenção familiar, bem como, características ambientais satisfatórias. Contrapondo, as dimensões tecnológicas e de sustentabilidade, uma vez, que o processamento e a conservação da lagosta a bordo são inadequados, levando a baixa qualidade, comprometendo sua comercialização.

Trata-se de uma pesquisa bibliográfica de abordagem qualitativa e caráter descritivo que tem como objeto de estudo o protagonismo do médico de família na visita domiciliar, que objetivou descrever as práticas desenvolvidas por médicos de família no contexto da visita domiciliar da Estratégia Saúde da Família. Como metodologia, utilizou-se a Biblioteca Virtual de Saúde, nas bases de informações LILACS, BDENF, MEDLINE e SCIELO, com recorte temporal de 2009 a 2018. Na medida em que o médico de família tem a oportunidade de acompanhar este usuário e sua família, a visita domiciliar (VD) pode tornar-se um espaço que propicia a interação e o diálogo, ultrapassando a questão técnica, exclusivamente. Conclui-se a importância do médico de família como educador e orientador na promoção da saúde, uma vez que é o profissional que possui conhecimentos técnicas e habilidades para realizar uma análise detalhada das condições do cliente idoso e do seu cuidador.

O trabalho de campo é importante, para desvendar as questões ambientais e, sobretudo, explorar o conteúdo dado em sala de aula de forma mais dinâmica e prática, diante dessa abordagem, teve como objetivo analisar os benefícios do uso da aula de campo como ferramenta metodológica para o ensino. Esse trabalho resultou na prática pedagógica adotada na Escola Municipal Profª Maria Eulália Vieira, na disciplina de Geografia, tendo como ponto de partida a água e sua importância para os moradores do município de Três Lagoas-MS. No local há um córrego que precisou ser encanado por causa do processo de urbanização que ocorreu na urbe. O foco foi esclarecer aos estudantes do 8º ano a sobre a questão ambiental inclusive nos parâmetros das políticas públicas municipal, sendo assim, utilizou-se uma sequência didática. No primeiro momento, apresentou um vídeo sobre São Paulo, “Entre Rios”; na continuação os alunos aplicaram questionários para os moradores do bairro Jardim Alvitrados, onde ocorre frequentes inundações. Em seguida, realizou-se uma saída de campo com os alunos para mostrar onde o córrego da Onça deságua. Por fim, com a interação dos alunos e analise dos questionários e imagens fotográficas, pode-se compreender as principais problemáticas ambientais do bairro, percebe-se que houve um progresso significativo na forma que compreenderem a importância da água e sua influência/relação com o meio ambiente.

A análise de indicadores relacionados à saúde ambiental em conglomerados sociais pode propiciar subsídios a tomada de decisões aos gestores públicos. Neste foco buscou-se associar as configurações de saúde ambiental (infraestrutura sanitária) e risco de ocorrência de casos de leptospirose, no entorno das 31 áreas com edificações do Programa Minha Casa Minha Vida, faixa 1, em Salvador - BA. A estratégia metodológica adotada incorporou a utilização de técnicas de geoprocessamento, para a espacialização das configurações de infraestrutura sanitária, com a criação de mapas temáticos e de densidade. Considerando os hotspots “zonas quentes” gerados observou-se que o processo de seleção das áreas à implantação dos projetos de habitação social obedece uma lógica excludente, concentrando pessoas vulneráveis socioeconomicamente em locais ambientalmente frágeis, implicando numa maior susceptibilidade de ocorrência de doenças negligenciadas. Considera-se como pressuposto estratégico, como contrapartida estadual e/ou municipal, o investimento público preventivo em saneamento básico, pela lógica da economicidade em saúde curativa. Ainda, deveria ser pré-requisito de planejamento, os parâmetros de sanidade ambiental aos empreendedores no processo de seleção, aprovação/liberação de fomento, execução de obras e “habite-se” aos usuários de habitações sociais destas áreas urbanas tangenciais.

Published: July 2020

In the last decade, exploration in high temperature and pressure wells has motivated the improvement of drilling fluids with the application of nanoparticles. In this context, nanoclay, the most available of nanoparticles, has been applied in the development of nanofluids, mainly associated with polymers. In parallel, among the polymers used, xanthan gum has been little explored for this purpose. In this work, the interaction between xanthan gum, hydrophobic nanoclay, sodium and calcium chloride and their influence on the rheological parameters of the mixture was evaluated in solution. The influence of temperature and hydration time on the rheological parameters of the mixture was also evaluated. For this purpose, nanoclay was first characterized with XRF, XRD and TGA. Then, a complete factorial design 24 was adopted, varying the concentrations of nanoclay, xanthan, sodium and calcium chlorides. Third, a Doehlert Matrix of the 7x5x3 type was adopted, varying the concentrations of nanoclay, xanthan and temperature, with the concentrations of the constant salts. In the fourth, select the effect of the hydration time on the color rheological parameters. Finally, Conductivity and Potential Zetas of sizes were verified, varying the concentration of the components and the hydration time of the mixtures. It was concluded that the interactions between the components of the mixture do not stabilize; the temperature, the salts have no significant influence on the rheology of the mixture; nanoclay in concentrations not exceeding 5% (m/v) interacts with the Minimum Shear Stress; the rheological parameters stabilize after 96h of hydration.
