Uso da cromatografia gasosa para avaliação da difusão em membrana de Polietileno de Alta Densidade (pead) em contato com hidrocarboneto

The constant petrol fuel leak in gas stations has caused concern in many countries around the world. Those fuels have toxic organic compounds in their composition, like Polycyclic Aromatic Hydrocarbons (PAH), which are harmful to the human health. In this work the efficiency of the protection layer with a High Density Polyethylene (HDPE) membrane of 2.5 mm thickness was evaluated. The study was based in the diffusive process in the intact membrane by a permeameter developed to evaluate the diffusive process. The membrane was putted in the middle of the system to separate two sides: a local soil impregnated with diesel oil (in one side) and pure water (in the other side). The chromatography technique was conducted to evaluate the contamination in the pure water. The analyses were made monthly in a total period of 6 months of research. The results tests show that the membrane was less effective to antracene and naphthalene compounds. Despite that, the results showed that the HDPE membrane is a good alternative to prevent contamination of water and soil by the compounds under study up to one year, based on the performance in the time of study.

Nível de atividade física e imagem corporal de alunos ingressos de um curso de educação física da Cidade de Santo André - SP

The aim of this study was to evaluate the level of physical activity confronting to the real and ideal body image of 65 individuals of both gender (27 women and 38 men) aged between 18 and 37 years old, all students of a Physical Education College of Santo André´s City - SP. The instruments used were the International Physical Activity Questionnaire, Short version (IPAQ, 2005) and Test for assessment of Body Image proposed by Stunkard et al., (1983) and adapted by Marsh and Roche (1996). According to the results, male subjects are more actives compared with female, as well as for the real and ideal body image males showed no significant difference, however, the females showed differences between the real and the ideal body image, between the gender no significant differences existed on the real and ideal body image. We can conclude that the students of this Physical Education College mostly presents in moderate or high level of physical activity, showing that the male are pleased with the real and ideal body image, and for a willing female body silhouette thinner ideal than real, with no significant differences between genders, and thus leading us to believe that the physical education College lead the students to experience practical activities becoming them lifestyle most active in search of a better quality of life and wellness.

A comunicação pública e o desenvolvimento e difusão da leitura no Brasil: estratégias da campanha 'Mãe, lê pra mim' do insituito Pré Livro

As transformações que tornam a sociedade mais complexa, configuradas na Sociedade da Informação, possibilitam novas formas de acesso as informações e conhecimentos que se manifestam em diferentes rela- ções sociais. No Brasil a valorização da leitura é um tema bastante recente, já que o Plano Nacional do Livro e da Leitura – PNLL - é de 2006. Tem como prioridade transformar a qualidade da capacidade leitora do Brasil e trazer a leitura para o dia-a-dia do brasileiro. Um dos eixos do plano é a Valorização da leitura e da comunicação, com ações para criar consciência sobre o valor social do livro e da leitura. O plano aborda a comunicação relacionada principalmente a dois aspectos: acesso à informação e comunicação sobre a leitura. A comunicação está sempre no centro da existência para qualquer sociedade, em desenvolvimento ou não. A partir de pesquisas sobre a leitura, o Instituto Pró-livro, uma entidade de caráter privado sem fins lucrativos, cujo objetivo principal é o fomento à leitura e à difusão do livro, utiliza-se de diversas estratégias de comunicação pública. Dentre essas experiências destacamos a Campanha “Mãe, lê pra mim?”, como uma prática de comunicação que busca levar informações aos cidadãos a partir do entendimento de se ouvir “as vozes locais”.

A estética da imagem na TV digital

This text reflects on the techniques and the process of image production and its artistic composition to digital television in high defini- tion, whereas the 4:3 and 16:9 formats will exist until shutdown of the analog signal. Within this period, consumers of television programming that have analog receivers will continue to see the images in 4:3 format. That fact determines that the productions in high definition, while capturing images with larger viewing area and have high contrast ratio (>1000:1) must be main- tain the elements of visual storytelling within the smallest area and with the contrast ratio of the analog tv (30:1), at the risk of distorting visually the messages produced by the directors.

Avaliação do consumo alimentar e percepção da imagem corporal de culturistas

In bodybuilding, sport that emerged in Brazil in the 70s, competitors are judged by physical appearance, size and muscle definition. The present study aimed to assess dietary intake, supplement use, and it also investigated body image perceptions of bodybuilders. Practitioners of three different gyms in the state of São Paulo participated in the study. They filled the anamnesis form containing data on food consumption and intake of supplements and also answered a questionnaire on the perception of body image (Satisfaction Scale with Body Appearance). The study showed a considerable food inadequacy with an average of carbohydrate intake of 41.84% ± 10.88%, of lipid, an average of 18.96% ± 6.40% and of protein 39.20% ± 10.41%. In pre-competition, the average of daily carbohydrate intake is reduced to 22.69% ± 12.34%, the lipid increases to 25.68% ± 14.0% and the protein increases to 51.63% ± 10.28%. It was observed that all individuals take some sort of supplement. Considering the perception of body image 60% of the appraised are fully satisfied with the muscular appearance and 40% has greater risk of developing vigorexia. As the bodybuilder has rigid dietary control, it is important nutritional monitoring. So it is necessary a better identification and guidance of risk groups for the development of body image disturbances through specialized professionals such as dieticians, psychologists and coaches for success training, aiming at physical and mental well being of the athletes.

Copa do Mundo 2014: a exploração da imagem dos jogadores

O futebol é uma das modalidades mais praticadas no mundo. Atualmente, estima-se que se tenha cerca de 3,5 bilhões de praticantes desta modalidade, sejam eles de forma profissional, ou no âmbito do lazer. Por consequência, o futebol torna-se um grande influenciador do comportamento social de crianças e adolescentes, transmitindo elementos para interpretação do mundo, confrontando, muitas vezes, com a escola e a família na formação de valores. Através das mídias, o futebol é disseminado mundo afora, por meio de transmissão de jogos, cobertura de campeonatos, programas exclusivos de futebol e publicidade, em que são exploradas as imagens dos atletas para venda dos mais variados produtos. Sendo assim, o objetivo desse estudo se pautou num levantamento, em que foram analisadas propagandas publicitárias nacionais ocorridas nos meses de Junho, Julho e Agosto de 2014, em mídia impressa, buscando compreender o tipo de publicidade exercida e quais jogadores ficaram em evidência. Para isso, a metodologia deste estudo foi do tipo qualitativa e descritiva, em que realizou-se uma análise documental acerca dos principais referenciais da área investigada, como reportagens e propagandas em jornal (Folha de São Paulo) e revistas (IstoÉ e Veja). Os resultados obtidos culminaram em três categorias temáticas, sendo elas: atletas atuais x atletas antigos; atletas cobertos x desnudos: corpos que são vendidos?; e tamanho da publicidade e relação com o megaevento. Na primeira categoria, viu-se ambas as gerações tiveram suas imagens associadas a atletas campeões, como forma de incentivo à busca do hexacampeonato. Na segunda categoria, verificou-se que os corpos dos atletas vendiam mais que produtos, vendiam status, eram retratados como símbolos a serem alcançados. Por fim, na última categoria, foram encontradas evidências que tanto o tamanho quanto as características das publicidades foram distintas no decorrer da Copa do Mundo...

The aim of this article is to discuss the limitations and benefits of each diagnostic imaging modality available in the veterinary medical field, and also to present the newest diagnostic imaging modalities in order to maximize and make more accurate diagnosis of thyroid diseases.

The feasibility of using wind energy for rural populations lacking electric power in Brazil

In the wake of current global image involving environmental impacts, the use of wind power has had a remarkable growth in recent years as a technique for generating electricity. In fact, it is a source featuring strong dissemination of technology which provides decrease in costs and a greater access to low-income electricity. PROINFA (Incentive Program for Alternative Energy Sources) promotes a greater diffusion of new technologies for power generation, in particular wind-produced. Due to such a scenario on the exploitation of such energy source, current analysis discusses strategies for the development of domestic wind technology and the implications for electricity-lacking rural areas. Analysis shows a similar behavior between rural populations lacking electricity and the amount of potential energy available in the region. It is expected that this assay will contribute towards the establishment of public policies for wind-energy parks on rural farms in the North and Northeast regions of Brazil.

Utilização de imagem de satélite Landsat no mapeamento da ocupação da terra e seus conflitos de uso em APPs na bacia hidrográfica do ribeirão Paraíso - São Manuel (SP)

The objectives of this study were to evaluate land use and occupation of Permanent Preservation Areas (PPA) as well as its use conflicts by TM (Thematic Mapper) image of the 2010 Landsat-5 satellite, according to the Forest Code. For that purpose, Geographic Information Systems in the Ribeirão Paraíso watershed, São Manuel, SP were used. The combination of Remote Sensing and Geographic Information System technologies allowed representation of spatial distribution of the landscape and data integration in the diagnosis of geographic interest. The 2010 mapping showed 12 use categories, and the sugar cane crop had the largest land occupation, 48.25% of the area. The areas of permanent preservation amounted to 925.74 ha, which is an ideal value based on the Brazilian legislation. Mapping of land use conflicts showed intensive anthropic actions going 80.13% forward on PPAs, with only 19.87% remaining forests, which highlights their negative impact and illegal situations in these areas.

Espacialização do uso da terra da microbacia do Córrego Monte Belo - Botucatu (SP), obtido por imagem de satélite de 2011 e fotografias aéreas coloridas de 2000

O presente trabalho teve como objetivo avaliar as variações de uso e ocupação do solo entre os cenários de 2000 e 2011 da microbacia do córrego Monte Belo – Botucatu (SP). Para tanto, utilizou-se de geotecnologias, sendo a integração de informações realizada no Sistema de Informações Geográficas (SIG) - IDRISI, aliada ao uso de cartas digitais do IBGE, escala 1:50.000, além de fotografias aéreas (2000) e imagens de satélite LANDSAT - 5 (2011). Através dos dados obtidos, foram detectadas três classes de uso do solo sendo que em 2000, elas correspondem ao reflorestamento, pastagem e mata ciliar e em 2011, reflorestamento, mata ciliar e solo exposto. Desta forma, pode-se concluir que as ferramentas de análise baseadas em SIGs trazem a possibilidade de analisar as variações no espaço e no tempo além de resultar em informações que podem subsidiar o planejamento da microbacia do Córrego Monte Belo.

Casuística dos exames de diagnóstico por imagem na medicina de animais selvagens - 2009 a 2010

The aim of this study was to retrospectively evaluate in the casuistry on class and systems frequently diagnosed in wild animals that were sent to the FMVZ–UNESP-Botucatu diagnostic imaging service. The class of birds was the most referred to the centers, followed by the mammals and reptiles. The majority of the requested tests were the radiographs and in a minor scale the tomography and ultrasound. Although the birds were the greatest number of animals sent to the service, mammals were the most radiographed for wound control. The most frequently observed system was the musculoskeletal caused by trauma, especially in birds. The radiograph was the most exam initially indicated, then the animal could be forwarded to other imaging modalities, which in wild animals medicine is still limited to research.
