Estudo sobre depósitos tecnogênicos no entorno da represa da Sabesp em Presidente Prudente-SP

The human being has a dependency with the natural environment, since it is from withdrawing resources from it is essential for their survival. But this relationship appears to be unbalanced from the moment that society emerges and changes the substrate in which land is located. In this context the study about the formation of technogenic deposits, has assisted in the preparation of environmental diagnoses in an area very changed by society. Technogenic deposits are sedimentary deposits originated by human activities in the environment, with special emphasis in this work in the fluvial plains. Their classification depends on both the manufactured materials found in its layers, and the processes that led to its formation. Thus, the main objective was to understand the formation history of technogenic deposits in the fluvial plains of the Santo Anastacio river and streams of Cedro and Cedrinho surrounding the dam of SABESP (Basic Sanitation Company of São Paulo) in Presidente Prudente-SP. The experimental proceedings are based mainly on realization of fieldwork to characterization study area, collection of technogenic materials in PVC´s (polyvinyl chloride) tube, and analysis of laboratory through of particle size analysis (EMBRAPA, 1997) of the technogenics layers...

Viabilidade técnica e econômica na utilização de um sistema fotovoltaico para alimentação de luminárias LED na Faculdade de Engenharia do Campus de Guaratinguetá SP

Solar energy can be considered the largest source of energy available on earth and has attracted in recent decades, attention and interest for its rational use. The use of energy sources in a sustainable way is essential to the survival of future generations, due to the scarcity of natural resources and their exploitation in a disorderly way. This academic work aims to bring a possible alternative to reduce the consumption of eletrical energy, at the University of Engineering – Campus of Guaratinguetá, through the use of a photovoltaic system interconnected to the LED bulbs. For this, the necessary data for the design of the photovoltaic system componentes and their acquisition costs were obtained and three differents configurations were developed to choose the one that bests fits the studied case, considering the return time of the initial investment (payback)

Diagnóstico Ambiental da Cidade de Presidente Bernardes - SP

The new modes of production imposed by capitalism and its relentless pursuit of development triggered several impacts on the natural environment and thereby the quality of life of society. These impacts become more visible when we look the urban place. For the identification and proposal of solutions is necessary to carry out an environmental diagnosis to have knowledge of the real situation of a given area. The Presidente Bernardes city is located in West of the São Paulo State, and even being a small city has many problems resulting of the unplanned urban growth. Thus, the present work intends to conduct an environmental diagnosis of the city Presidente Bernardes-SP, through the analysis of water supply systems, sewage treatment, collection and disposal of solid waste and green areas in the urban area and if required, indicate plausible alternatives to solve any problems

Indicadores Antropométricos do Estado Nutricional de Idosas Praticantes e Não Praticantes de Exercício Fisíco na Zona Norte de São José do Rio Preto-SP

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profile of the elderly who also used walking as a means of getting around.

Qualidade microbiológica de bebidas lácteas fermentadas, com adição de polpas de frutas, comercializadas na região de São José do Rio Preto, SP.

As bebidas lácteas fermentadas são produtos formulados contendo iogurte, soro de leite, polpa de frutas, além de outras matérias-primas e aditivos permitidos. O produto final deve apresentar os micro-organismos de forma viável e abundante. Sua popularidade vem aumentando significativamente, principalmente devido aos seus benefícios nutricionais, ao menor custo do produto para o fabricante, à redução do preço final para o consumidor e por apresentar baixa viscosidade, sendo consumida como bebida suave e refrescante. Apesar do processo de fabricação ser considerado simples, utilizando-se principalmente os equipamentos disponíveis nas indústrias lácteas, estes produtos podem estar sujeitos à contaminação microbiana, quando não atendidas as condições elementares de higiene e sanidade. Tal contaminação pode ser representada por leveduras, coliformes totais, termotolerantes e bolores. Considerando os aspectos mencionados, o objetivo deste trabalho foi avaliar a qualidade microbiológica de bebidas lácteas fermentadas, com adição de polpas de frutas, comercializadas na região de São José do Rio Preto û SP, por meio das seguintes análises microbiológicas: contagem de bolores e leveduras, determinação do Número Mais Provável (NMP) de coliformes totais, temotolerantes e pesquisa de Escherichia coli e de Salmonella spp. Foi ainda efetuada a determinação do pH eletrométrico. Após a obtenção dos resultados verificou-se que 20% das amostras analisadas não atenderam ao padrão microbiológico estabelecido na legislação vigente, para coliforme termotolerentes, evidenciando positividade na pesquisa de Escherichia coli, sendo por este motivo, considerados como produtos em condições sanitárias insatisfatórias, portanto, produtos impróprios para o consumo humano.(AU)

Aproveitamento de sementes de abóboras (Cucurbita sp) como fonte alimentar

Brazil processes much of its fruit by producing natural juices, candy preserves, extracts and pulps; however, almost 60% of their total weight derives from peels, leaves and seeds. As a result, the emphasis lies most strongly on the use of waste, especially waste that is not commonly used by the food industry or by consumers. The use of seeds would increase the viable sources of raw materials, lower operating costs of industries and would promote the development of new food products, since they are our main sources of protein, fat, fiber, functional compounds, vitamins and minerals salts. This paper presents alternatives for the use of pumpkin seeds (Cucurbita sp), which are often underutilized or discarded. It also demonstrates the bioactive and anti-nutritional compounds and their health effects.

Biological Hydrogen production from environmental sample in tropical countries

The hydrogen gas is regarded as clean and renewable energy source, since it generates only water during combustion when used as fuel. It shows 2.75 times more energy content than any hydrocarbon and it can be converted into electrical, mechanical energy or heat. Inoculum sources have been successfully tested for hydrogen biological production in temperate climate countries as sludge treatment plants sewage, sludge treatment plant wastewater, landfill sample, among others. However, hydrogen biologic production with inoculum from environmental samples such as sediment reservoirs, especially in tropical countries like Brazil, is rarely investigated. Reservoirs and fresh water lake sediment may contain conditions for the survival of a wide variety of microorganisms which use different carbon sources mainly glucose and xylose, in the fermentation. Glucose is an easily biodegradable, present in most of the industrial effluents and can be obtained abundantly from agricultural wastes. A wide variety of wastewater resulting from agriculture, industry and pulp and paper processed from wood may contain xylose in its constitution. Such effluent contains glucose and xylose concentrations of about 2 g/L. In this sense, this work verified hydrogen biological production in anaerobic batch reactor (1L), at 37 ° C, initial pH 5.5, headspace with N2 (100%), Del Nery medium, vitamins and peptone (1 g/L), fed separately with glucose (2g/L) and xylose (2 g/L). The inoculum was taken from environmental sample (sediment reservoir Itupararanga - Ibiúna - SP-Brazil). It was previously purified in serial dilutions at H2 generation (10-5, 10-7, 10-10), and heat treated (90º C - 10 min) later to inhibited the H2 consumers. The maximum H2 generations obtained in both tests were observed at 552 h, as described below. At the reactors fed with glucose and xylose were observed, respectively, 9.1 and 8.6 mmol H2/L, biomass growth (0.2 and 0.2 nm); consumption of sugar concentrations 53.6% (1.1 glucose g/L) and 90.5% (1.8 xylose g/L); acetic acid generation (124.7 mg/L and 82.7 mg/L), butyric acid (134.0 mg/L and 230.4 mg/L) and there wasn’t methane generation in the reactors. Microscopic analysis of biomass in anaerobic reactors showed the predominance of Gram positive rods and rods with endospores, whose morphology is characteristic of H2-generating bacteria, in both tests. These species were selected from the natural environment. In DGGE analysis performed difference were observed between populations from inoculum and in tests. This analysis confirmed that some species of bacteria were selected which remained under the conditions imposed on the experiment. The efficiency of the pre-treatment of inoculum and the imposition of pH 5.5 inhibited methane-producing microorganisms and the consumers of H2. Therefore, the experimental conditions imposed allowed the attainment of bacterial consortium of producer H2 taken from an environmental sample with concentration of xylose and glucose similar to the ones of the industrial effluents.
