The present study aimed at evaluating the productive performance of Leporinus macrocephalus fed with different levels of inclusion of poultry viscera meal replacing fish meal. The experiment was conducted in a stove located in the Universidade Estadual do Oeste do Paraná during 45 days. We used 200 fish with average initial length of 4.7 ± 0.37 cm and average initial weight of 1.407 ± 0.03 g, distributed in 20 net-cages. The experimental design was randomized with five treatments and five replicates with five levels of replacement of fish meal by poultry viscera meal (0, 25, 50, 75, 100%). The parameters evaluated were the productive performance and the chemical composition of animals. The inclusion of poultry viscera meal in the substitution of fish meal in the feeding of Leporinus macrocephalus can be used without impairing the performance of the animals.

The objective of this work was to evaluate the hematological and parasitological responses of tambacu (Colossoma macropomum x Piaractus mesopotamicus) subjected to catch-and-release stress and to different stocking densities in a catch-and-release system. Two hundred and ten fish with mean initial weight of 785.33±152.02 g and mean total length of 34.43±2.21 cm were maintained in ponds and divided into three groups: without fishing and low density (G1), with fishing and low density (G2), and with fishing and high density (G3). No significant differences were observed between the mean values for hemoglobin concentration, erythrocyte number, differential counting of leukocytes, and glucose. The fish from the G3 group showed higher parasite and thrombocyte numbers, and lower weight gain and hematocrit. The activity of catch-and-release, associated with high stocking density, can disrupt organic balance and animal performance, favoring parasitosis.

Esse trabalho tem por objetivo, mostrar a evolução do sistema de transporte coletivo intermunicipal do Estado de São Paulo. Nesse sentido, partimos do processo de industrialização e nacionalização da indústria automobilística. Procuramos também mostrar a evolução do Departamento de Estradas e Rodagem [DER], no papel de direcionador e gerenciador do sistema. Nesse processo, detalhamos o papel de todos os governos do Estado de São Paulo, na implantação de sistema viário estadual [1950-2006]. Também procuramos demonstrar o surgimento dos principais grupos que monopolizam cada vez mais o setor dos transportes coletivo intermunicipal. Assim, vamos comprovar a tese de que as empresas do transporte coletivo intermunicipal estão utilizando as linhas suburbanas para fazer frente ao grande avanço do transporte clandestino intermunicipal no Estado de São Paulo.

Transport is one the essential services for the development of most economic activities. In the forestry sector, the main transport used to carry wood from the forest to local consumption is road. The transport increases the producing costs of wood and may be responsible of a high percentage in the final price of the wood sold in the industry. To reduce the company’s costs and increase the efficiency of forest production those transport activities must be analyzed and improved. In that context, an economic analysis is the main objective of this work, evaluating three different types of log transport from a sawmill in São Paulo´s Southwest region. For this, a data collection was done to compound the costs and the incomes of timber transport, and that way, to do the economic analyses of each transport. The monitoring activities were done in the second 2013 half-year and the research achieved economic viability results utilizing tools and methods of Economic Engineering

A área de estudo deste trabalho engloba as bacias hidrográficas dos rios Aguapeí e Peixe, localizadas a Oeste do Estado de São Paulo. Estas por sua vez estão vinculadas aos Comitês de Bacias Hidrográficas Aguapeí e Peixe (CBH-AP). Diante da iminência da implementação da política de cobrança pelo uso dos recursos hídricos nessa área, o presente trabalho apresenta em linhas gerais o estudo da vazão específica de forma que os resultados possam contribuir com os órgãos públicos de gestão a fim de que se execute uma gestão mais efetiva dos recursos hídricos. Com base em dados hidrológicos das estações fluviométricas inventariadas através do Sistema Integrado de Gestão de Recursos Hídricos do Estado de São Paulo (SIGRH) e da Agência Nacional de Águas (ANA) nas duas bacias hidrográficas, procedeu-se o estudo da vazão específica. Os resultados desses estudos apontam para uma maior variabilidade da vazão específica média na bacia hidrográfica do rio do Peixe, uma vez que ao longo da série histórica essa bacia apresenta maiores valores de vazão, foi possível também observar as mudanças no comportamento da vazão hidrológica nas duas bacias hidrográficas, ou seja, através dos três períodos hidrológicos identificados foi possível depreender que a vazão específica média em um período se mostra bem distribuída em ambas as bacias hidrográficas, em outro período hidrológico essa distribuição já se apresenta mais desigual. Tais informações possibilitam aos órgãos de gestão um planejamento mais refinado e eficiente

The expansion of the energy matrix is a matter of great importance since the recent problems facing the country in this sector, such as rationing mobilized in 2001. Moreover, there is also concern with global sustainable development. Brazil is producing about 64 million cubic meters of biogas per day, but only a small percentage of this total is harnessed as an energy resource. Compounders are considered potential, for example, landfill energy (LE) and sewage treatment plants (STP), which can be adapted to produce biogas and market them. The work focuses its studies on biogas produced by these small and medium compounders. Are proposed and studied the following alternatives for the utilization of biogas energy: generation and sale of electricity through the installation of a small power station within the landfill, and purification and marketing of gas, whose price will be a consideration on the price of natural gas, taking into account the percentage of methane present in the biogas. Trade ensures that gas plus a destination ecologically appropriate to it, taking advantage of its energy

This study aims to analyze the intermunicipal collective transportation in The State of São Paulo, according to the relation of lines per permittee company of June/2002 and June/2012. We worked on the suburban and road bus lines. After analyzing the data, we seek to know how was the evolution of these lines in the State of São Paulo, the regions in which these lines were more developed and the groups that monopolize increasingly the intermunicipal collective transportation. It was made a list of some variables that enabled a comparison with the road system and we also showed the considerable increase of the suburban lines, which became more common as time goes by to compete against the clandestine transportation

The São Paulo State has as one of its main rivers the Tietê, which is an extremely important source because of its biodiversity, use in navigation and mainly as direct supplier of water for thousands of people in the region. Currently, the biodiversity of marine and freshwater ecosystems has been threatened, primarily by environmental problems resulting from the degradation of ecosystems, an example is the stretch of the Middle Tietê River, where the Barra Bonita dam (SP) focused virtually the whole load organic effluents from the metropolitan region of São Paulo, leading to eutrophication with the loss of water quality. This basin is located in the Peixe’s River, a tributary of the Barra Bonita whose sources are on the slopes of the Cuesta de Botucatu, presenting an altitudinal gradient in a good state of conservation and water quality. From another perspective, the studies related to parasites and other pathogens of aquatic organisms have considerably increased the relevance, especially those hosts with potential for growing and marketing, given the significant increase these activities in Brazil and worldwide. Among the agents responsible for diseases in fish are the myxosporean, which can cause major economic damage, with high mortality ratios. Based on the above, this study evaluated the biodiversity of myxosporean parasites of two species of fish Acestrorhynchus lacustris and Steindachnerina insculpta. During the period January to November 2012, 40 specimens of Acestrorhynchus lacustris and 33 specimens of Steindachnerina insculpta were collected from the Peoxe’s river at four different points. The necropsies were performed and all organs were analyzed looking for myxosporean. Only the species Steindachnerina insculpta had their gills parasitized by two species of the genus Henneguya

Sabe-se que as substâncias presentes na fumaça do cigarro provocam alterações no sistema respiratório, incluindo alterações no transporte mucociliar. Objetivo: Comparar o transporte mucociliar de indivíduos tabagistas e abstênicos, e correlacioná-lo à função pulmonar e a história tabagística. Metodologia: Foram avaliados 65 indivíduos, divididos em 2 grupos, grupo abstênico (G1) e grupo controle (G2). Primeiramente, foi realizada uma entrevista inicial para obtenção de dados pessoais, antropométrico e histórico tabágístico. Após foram avaliados quanto à função pulmonar (espirometria), quantificação do monóxido de carbono no ar exalado (COex) e do transporte mucociliar nasal (tempo de trânsito de sacarina-TTS). Todas as avaliações foram realizadas após um período de doze horas, 7 e 15 e 30 dias de abstinência do cigarro. Método estatístico: A descrição dos resultados foi apresentada como média e desvio padrão. Para comparação dos grupos foi utilizado ANOVA para medidas repetidas, não paramétrico, seguido do teste Volm-hidak. O nível de significância utilizado foi de p<0.05. Resultados: Houve diferença estatística entre o TTS no grupo abstênico a partir de 15 dias em relação ao valor basal. Não houve correlação entre o transporte mucociliar basal e as variáveis. Conclusão: Indivíduos que cessam o hábito tabagístico, após 15 dias de abstinência, já é possível verificar melhora na depuração mucociliar e esta se mantém na faixa de normalidade até o 30º dia

Understanding the linkages between the natural elements is essential for being promoted the land use, occupation and sustainable management of environmental systems. Universal Soil Loss Equation (USLE), as a predictive model of erosion, is important to allowing the prevention of possible environmental impacts which may drastically interfere in natural or anthropic environments, as well as prevent potential financial wastes and even contribute to greater efficiency of agricultural production. This research will be working some USLE parameters, emphasizing topographic factor from Ribeirão Monjolo Grande watershed. Among the factors considered by the USLE, the Topographic Factor interferes directly in the erosive dynamic of a watershed because it involves variables related to hydrological processes that occur on it. In this research, were discussed different methods for obtaining the Topographic Factor (BERTONI e LOMBARDI NETO, 1985; MOORE e BURCH, 1986; DESMET E GOVERS, 1996) in GIS environment. After comparison between the methods, was indicated that best represents the conditions of geometry strand of the study area. Finally, other factors (R, K, C, P) considered by the USLE were obtained. The attainment of these parameters were guided by the use of geotechnologies, especially in Geographic Information Systems (GIS), with the assistance of secondary data and periodic field visits. The results obtained contributed to the understanding of hydrosedimentological dynamic in this area and serve as a viable strategy for studies of soil loss, aiming at developing consistent material for future researches about environmental planning and land management

O transporte mucociliar é um mecanismo de defesa muito importante do trato respiratório, e é por meio deste que agentes agressores são carregados e expelidos. As substâncias presentes na fumaça do cigarro provocam mudanças no sistema respiratório, incluindo no transporte mucociliar. Objetivos: Avaliar o efeito agudo do fumo no transporte mucociliar de indivíduos tabagistas em diferentes momentos e comparar com grupo controle. Métodos: Foram avaliados 20 tabagistas (10 homens; 46 ± 13 anos; 26 ± 22 anos/maço; 19 ± 10 cigarros/dia) em quatro momentos: após 12 horas de abstinência, imediatamente, 20 minutos e 2 horas após fumar. No primeiro momento foram obtidos dados pessoais, história tabágica (anos/maço, cigarros/dia e grau de dependência de nicotina), e após 12 horas em abstinência do tabaco foi realizado o teste de função pulmonar (espirometria), quantificação do monóxido de carbono no ar exalado (COex) e mensuração do tempo de trânsito de sacarina (TTS) ...(Resumo completo, clicar acesso eletrônico abaixo)
