    Get PDF
    O presente artigo procura avaliar a política de terror como estratégia de controle social a partir da constituição de uma natureza feminina e de propostas para sua remodelagem. Para tanto, foram analisadas mensagens eletrônicas (hoaxes) que circulam na internet. Tais mensagens acabam por propor a segregação social de grupos minoritários. A temática base de tal remodelagem é garantida pela difusão do terror, que serve a estratégias de controle social

    A ampliação do acesso ao ensino superior público por meio da política de expansão e reestruturação das universidades federais se deu a partir de 2007, com a criação do REUNI, e procurou atender, especialmente, os cursos noturnos. Após a adesão da Universidade Federal da Bahia (UFBA) a esta política, algumas mudanças ocorreram, sobretudo na estrutura física da instituição e no perfil socioeconômico do estudante. O presente artigo tem o objetivo de analisar o perfil dos estudantes dos cursos noturnos de saúde, criados no âmbito do REUNI, e suas percepções sobre as implicações da estrutura física da UFBA para a formação acadêmica. Utilizou-se como metodologia questionário socioeconômico e entrevistas semiestruturadas aos estudantes dos cursos noturnos de saúde, cujos dados foram analisados de forma qualitativa e apresentados a partir de tópicos e categorias de análise. Sua discussão se fez à luz dos autores que analisam as políticas públicas de educação para o ensino superior, chegando-se à conclusão que a UFBA teve enormes avanços do ponto de vista da inclusão social e da implantação de cursos com nova modalidade curricular, com regime de ciclo, flexível e interdisciplinar, mas que ainda precisa avançar em relação a espaços físicos como a biblioteca e o Restaurante Universitário

    The service life of buildings can be associated with the durability of enveloping the elements, e.g., the flat roofs that are constantly exposed to environmental agents. Waterproof membranes, produced with bituminous or polymeric materials, usually protect these elements. This paper presents an experimental study of waterproofing systems subjected to environmental agents of degradation. Four types of membranes were tested: bituminous, polyurethane, acrylic and acrylic with polyester mesh. All membranes were applied to concrete substrates and exposed to cycles of 48 hours in 70°C oven and 24 hours in immersion vats with 23°C water. The specimens were subjected to 0, 4, or 8 cycles and submitted to pull-off tests. The results demonstrated that the waterproof system behavior change when subjected to cycles of the temperature gradient. The tests show that the different thermal deformation between the membranes and the concrete substrate results in loss of adhesion

    [Resumo] Este artigo apresenta o processo participativo de estruturação do monitoramento e avaliação de projetos e políticas públicas de educação ambiental (EA) no Brasil. O processo vem sendo desenvolvido pela ANPPEA – Articulação Nacional de Políticas Públicas de Educação Ambiental com o objetivo geral de contribuir para o fortalecimento das políticas de transição para sociedades sustentáveis no país. Deste modo, está em desenvolvimento uma plataforma digital ancorada em um banco de dados subsidiado por indicadores de monitoramento e avaliação. O arcabouço teórico-metodológico que dá suporte ao projeto da Plataforma Brasileira de Monitoramento e Avaliação de Políticas Públicas de Educação Ambiental está referendado em políticas públicas multicêntricas, nas quais governo e sociedade têm responsabilidades compartilhadas e se colocam como parceiros para a formulação, implementação e monitoramento das políticas. O arcabouço permite também um olhar multiescalar sobre as políticas públicas de EA, partindo da identificação de atores em suas diversas áreas e escalas de influência espacial, oferecendo relevantes elementos para as análises da extensão e relação entre políticas públicas nos territórios. Até o momento cerca de 300 pessoas de representações diversas foram envolvidas neste processo que resultou no diagrama de dimensões articuladas de indicadores de monitoramento e avaliação de políticas públicas de EA.[Abstract] This paper introduces the participatory design of monitoring and evaluation framework for projects and public policies in environmental education in Brazil. This process has been developed by ANPPEA – National Articulation of Enviromental Education Public Policies, with the general objective of contributing to the strengthening of the policies of transition to sustainable societies in the country. Thus, a digital platform based on database and indicators of monitoring and evaluation is under development. The theoretical-methodological framework that supports the Brazilian Platform for Public Policies in Environmental Education Monitoring and Evaluation project is based on multicentric public policies concept which govern and society has shared responsability and put themselves as partners to the formulation, implementation and monitoring of public policies. This framework also allows a multiscalar approach over public policies of environmental education, starting from the identifcation of actors in their diferent felds and spatial scales, providing relevant subsidies for the analysis of the extension and relationship between public policies in the territory. So far, about 300 people from diferent sectors were involved in the process that resulted in the diagram of articulated dimensions of indicators for monitoring and evaluation of public environmental education policies

    BACKGROUND: Chronic venous disease (CVD) is to change the system causing a venous valvular incompetence associated with obstruction of flow or not. It affects 10 to 20% of world population, with higher prevalence in females. It presents as the most common symptoms and pain and swelling in advanced form, venous ulcer, and brings functional limitations, social isolation, affecting quality of life. OBJECTIVE: Profiling of patients with CVD, the survey data indicate that clinical and socio-demographic characteristics that may contribute to possible change of habit in the life, who for reasons of work, lack of knowledge and/or instructions had affected their routine by the disease, with consequent decline in their quality of life. METHODS: A descriptive, observational, cross-sectional study that evaluated patients with CVD treated at health centers in Maceió (AL) Brazil, applying a form for collecting data, such as CEAP, Brazil Criterion of Economic Classification Questionnaire and SF-36. RESULTS: The sample consisted of 66 patients with CVD, 83% were female and 17% male. The patients had predominantly aged between 50 and 60 years who were sedentary, assuming prolonged standing, low educational level and economic status, severe clinical disease (symptomatic C6), and quality of life variable. CONCLUSION: The results showed a predominance of females, 50 to 60 years old, with triggering factors and/or aggravating factors for development of CVD as lack of physical activity, low education and low economic income, affecting quality of life.CONTEXTO: A doença venosa crônica (DVC) consiste em alteração do sistema venoso causando uma incompetência valvar associada à obstrução de fluxo ou não. Acomete 10 a 20% da população mundial, tendo maior prevalência no sexo feminino. Apresenta como sintomas mais comuns dor e edema e na forma avançada, a úlcera venosa. Traz limitações funcionais e isolamento social, afetando a qualidade de vida. OBJETIVO: Traçar o perfil dos portadores de DVC, pelo levantamento de dados clínicos e sociodemográficos que indiquem características que possam contribuir para possível mudança de hábito na vida de pacientes que, por motivos de trabalho, falta de conhecimento e/ou instruções, tiveram sua rotina afetada pela doença, com consequente diminuição da sua qualidade de vida. MÉTODOS: Estudo descritivo, observacional do tipo transversal, sendo avaliados portadores de DVC atendidos em centros de saúde de Maceió (AL), aplicando um formulário para coleta de dados, como classificação CEAP, Critério de Classificação Econômica Brasil e Questionário SF-36. RESULTADOS: A amostra foi composta por 66 pacientes com DVC; 83% eram do sexo feminino e 17%, do masculino, a faixa etária predominante foi entre 50 a 60 anos; eram sedentários, assumindo ortostatismo prolongado, baixo nível de escolaridade e classe econômica, doença clínica grave (C6 sintomático) e qualidade de vida variável. CONCLUSÃO: Os resultados demonstraram predomínio da doença no sexo feminino, entre 50 a 60 anos de idade, com fatores desencadeadores e/ou agravantes para desenvolvimento da DVC como falta de atividade física, baixo nível de escolaridade e baixa renda econômica, afetando a qualidade de vida.FAL curso de FisioterapiaUniversidade Federal de São Paulo (UNIFESP)Universidade Estadual de Ciências da Saúde de AlagoasUNIFESPSciEL

    Introducción: los carretilleros son una clase especial de trabajadores responsables de la recolección, transporte y disposición de desechos, participando del proceso de recolección y clasificación de desechos, con gran aporte socioeconómico y ambiental en la sociedad. Objetivo: El objetivo de este estudio es describir los aspectos clínicos y sociales relacionados con el tipo y la condición del trabajo realizado por los animales. Métodos: 61 caballos fueron incluidos en este estudio. Cada propietario realizó una encuesta que contenía la identificación y caracterización de los animales, el estado de la silla de montar, los utensilios de trabajo, la manipulación de alimentos y el historial médico de los animales. Las respuestas fueron evaluadas por distribución de frecuencia. Resultados: De acuerdo con las respuestas de los dueños el 76,6% (36/47) de las sillas se encontraban en buenas condiciones, un 21,28% (10/47) en regular estado, y solo un 2,13% (1/47) en mal estado; catorce carretilleros no respondieron a esta pregunta. La mayoría de los propietarios informaron utilizarla el mayor tiempo posible y algunas veces piezas de espuma, trozos de tela, alfombras o mantas, sobre todo cuando no había erosión de la protección de la silla más baja, conocida como sudoración. En algunos casos, cables son utilizados para mantener esta protección, dando lugar a lesiones en la piel del animal. Conclusión: El nivel educativo de los propietarios de animales de tracción tiene gran influencia en la crianza de estos animales y sus consecuencias. Los futuros estudios sobre la biomecánica del sorteo será de gran importancia para la corrección empírica de gestiones a la que estos animales son sometidos. Son necesarios más estudios para cuantificar la influencia del ambiente sobre las lesiones en este tipo de caballos.Introduction: Carters are a special class of workers responsible for the collection, transportation, and disposal of waste and for participating in the collection and classification of waste with high socio-economic contribution and environmental society. Aim: The aim of this study is to describe the clinical and social aspects related to the type and condition of work done by animals. Methods: 61 horses were included in this study. Each owner took a survey that contained the identification and characterization of the animals, state of the saddle, work utensils, food handling, and animal’s medical history. The responses were assessed by frequency distribution. Results: According to the responses of the owners, 76.6% (36/47), 21.28% (10/47), and 2.13% (1/47) saddles were in good condition, normal state, only poor state, respectively. A total of 14 carters did not respond to this question. The majority of the owners reported the use of saddles for as long as possible and sometimes the use of foam inserts, pieces of cloth, rugs, or blankets as well, particularly when there was erosion of the protection of the lowest saddle, known as sweating. In some cases, cables were used to maintain this protection, leading to injuries on the animal’s skin. Conclusion: The educational level of the owners of the traction animals has a huge influence on the rearing of these animals and its consequences. Future studies on biomechanics would be of great significance for the empirical correction of the efforts to which these animals are subjected. More studies are necessary to quantify the influence of environment on lesions of this type of equines

    Optimization of heterologous protein production in Chinese hamster ovary cells under overexpression of spliced form of human X-box binding protein

    Background: The optimization of protein production is a complex and challenging problem in biotechnology. Different techniques for transcription, translation engineering and the optimization of cell culture conditions have been used to improve protein secretion, but there remain many open problems involving post-translational modifications of the secreted protein and cell line stability. Results: In this work, we focus on the regulation of secreted protein specific productivity (using a recombinant human immunoglobulin G (IgG)) by controlling the expression of the spliced form of human X-box binding protein (XBP-(s)) in Chinese hamster ovary cells (CHO-K1) under doxycycline (DOX) induction at different temperatures. We observed a four-fold increase in specific IgG productivity by CHO cells under elevated concentrations of DOX at 30°C compared to 37°C, without detectable differences in binding activity in vitro or changes in the structural integrity of IgG. In addition, we found a correlation between the overexpression of human XBP-1(s) (and, as a consequence, endoplasmic reticulum (ER) size expansion) and the specific IgG productivity under DOX induction. Conclusions: Our data suggest the T-REx system overexpressing human XBP-1(s) can be successfully used in CHO-K1 cells for human immunoglobulin production

    In order to understand the physiological demands and possible changes resulting from effort in horses and determine the type and intensity of exercise performed in equestrian polo of low handicap, we analyzed the negative logarithm of the activity of hydrogen ions (pH), carbon dioxide partial pressure (pCO2), oxygen partial pressure (pO2), the concentration of plasma bicarbonate ions (HCO3-) and serum concentrations of Na+, Cl- and K+ of seven healthy horses after a polo match of low handicap. Variables pCO2, pO2 and HCO3- were the only parameters that were significantly different before and after the match, and there were no significant hydroelectrolytic changes. It was possible to classify the low handicap polo as an exercise of short duration and varying intensity, considering the lack of change in the hydroelectrolytic balance. The exercise to which the animals were subjected is compatible with their athletic fitness

    Antimicrobial Activity of Plasma Rich in Platelets (PRP) on the Ocular Microbiota of Healthy Horses from Minas Gerais

    In equine ophthalmology, ulcerative keratitis is among the most common conditions and, in general, arises as a consequence of some trauma suffered. Secondarily, subsequent contamination by pathogenic or resident bacteria of the horse\u27s ocular microbiota may have undesirable consequences. Under physiological conditions, the normal microbiota coexists with the immune status of the host, serving as a barrier, ensuring the health of the ocular surface, and inhibiting the proliferation of pathogens. However, in the imbalance of immune barriers, the normal microbiota can become pathogenic and lead to infection, acting as an opportunistic agent. The present study aims to demonstrate the antimicrobial effect of platelet-rich plasma (PRP), its time of action, and its correlation with the concentration of its same components in vitro on Staphylococcus sciuri, a bacterium with high prevalence in the normal ocular microbiota of horses in the municipality of Minas Gerais. For the preparation of the PRP, eight adult Quarter Horse (QH) horses were used. The individual PRP was prepared by the double centrifugation protocol, and then, the PRPs were added to a pool, followed by testing their interaction in culture with Brain Heart Infusion (BHI) broth at different dilutions against five strains collected from different animals. After 3, 6, 12, and 18 hours, the colony formation units (CFU) count on a 5% horse blood agar plate was evaluated for each time point. Our study showed that Staphylococcus sciuri, the resident microorganism of the ocular conjunctival microbiota of horses, is more susceptible when compared to the standard strain “American Type Culture Collection” (ATCC-29213) Staphylococcus aureus, a pathogenic microorganism, which was used for the validation of our study. The antibacterial effect shown in this study was bacteriostatic for up to 6 hours. The most concentrated PRP dilutions, 1 : 1 and 1 : 2, were also most effective, suggesting that the antibacterial effect is volume dependent
