The changes occurring in Brazilian agriculture, with the inclusion of agro-industrial activities in your mode of production, must be analyzed to verify the changes in the behavior of territorial dynamics. Through changing the Rural Complex, traditional for the Agroindustrial Complex tightly integrated with trade and industry brought many consequences for the rural population, with regard to employment. Understanding this transformation capitalist the field is needed to analyze the actors involved in this process and the policies adopted for the expansion of sugar and ethanol activity in the State of São Paulo and the consequences for the spatial organization. The expansion of cane production areas were governed by the Institute of Sugar and Alcohol (IAA), the National Alcohol Program (PROÁLCOOL) Development Plan for the West of São Paulo - PRO-WEST and Expansion Program for the production of Canavicultura for production of fuel for the State of São Paulo (PROCANA). The occupation of these agroindustrial facilities in rural spaces contextualized by territorialization of the rural complex, in that sense, understanding these concepts is a key part development in the research. therefore, are concepts of fundamental importance to geographical science, and interpreting their function and construction in rural spaces

O cerrado é o segundo bioma mais representativo do Brasil, correspondendo a 23% do território brasileiro. É considerado um hotspot de biodiversidade, apresentando-se bastante ameaçado. Sua devastação é devido, principalmente, ao avanço das culturas agroindustriais de grande mercado. Sabe-se da importância da polinização para a reprodução de inúmeras espécies vegetais. Neste contexto, as abelhas desempenham um papel fundamental devido à sua dependência e especialização na coleta de recursos florais. Mas, estas também requerem locais propícios à nidificação. Além da destruição do hábitat através da fragmentação, a composição da paisagem que permeia fragmentos de vegetação nativa pode influenciar a diversidade apícola e afetar de forma diferente as espécies de acordo com seu hábito de nidificação e alimentação. É fato que as espécies mais especializadas tornam-se mais vulneráveis às alterações ambientais por apresentarem exigências particulares e pouca plasticidade na obtenção de recursos. A fim de analisar a interação entre diversidade de abelhas e Ecologia da Paisagem, foram selecionados dois levantamentos de fauna apícola (Itirapina – SP e Pirassununga – SP). Para isso foram elaborados mapas de uso e ocupação do solo através do SPRING 5.1.7 e, posteriormente, gerados os índices de Ecologia de Paisagens selecionados para o estudo com o auxilio do aplicativo FRAGSTATS 2.0. As espécies coletadas em ambas as áreas foram separadas em guildas funcionais de forrageamento e nidificação. A área de estudo de Itirapina foi sub-dividida em 13 classes de uso e ocupação da paisagem e a área de estudo de Pirassununga foi sub-dividida em 7 classes, conforme as características presentes em cada área. Entretanto, foi dado destaque às três principais classes de estudo: remanescentes florestais, uso antrópico e água para Itirapina... (Resumo completo, clicar acesso eletrônico abaixo)

Geophysics studies in areas impacted by petroleum derivatives describe abnormalities of both low and high electrical resistivity (the opposite of electrical conductivity), confirmed as contaminant phase by chemical analysis: this contradiction can be explained by degrading processes that naturally occur and create sub products that can change the environment conductivity. Monitoring the variation of the parameters mentioned serves as a comparative basis to the variation in geoelectrical parameters, which identified the correlation between the same contaminant parameters and the difference between their behavior studied apart, as well as its relations with the biodegradation process. The results are applied to the fuel distribution and storage sectors, leading to the diagnosis and monitoring of possible groundwater contamination scenarios, and the knowledge of the area exposure time to the contaminant, besides the better remediation alternative and impacts control. Among some conclusions, the most significant are the decrease in conductivity over time, so as the increase in Eh value in the gasoline contaminated tank, as well as the decrease in the pH value in the second tank with ethanol, which can be attributed to its degradation. Comparing the variations in both tanks, it is evident that Eh, pH and electrical conductivity do not behave temporally in a similar way, although some correlations between Eh and pH can be related.

The cassava wastewater, generated during the cassava processing, is a pollutant and toxic waste. This study compared the efficiency of the cassava wastewater treatment in three batch aerobic systems with a ru1nning time of 24 hours, and aeration stoppage of 12h with 2,500, 6,000 and 10,000 mg COD L-1 . The systems were evaluated for COD, pH, SVI and F/M. The results showed that the reactor with aeration stoppage for 12 hours, with 2,500 mg COD L-1 , presented the best reduction in a process with considerable energy consumption saving compared to traditional continuous systems.

Isolate microorganisms that fermenting xylose to ethanol is a challenge to expand production of biofuels from lignocellulosic materials. For this work was tested fermentation of xylose by yeast strains isolated from grape skins (Vitis spp) in order to ethanol produce. The yeasts were grown in submerged fermentation with xylose as a carbohydrate source. Aliquots were taken every 24 hours to measure cell growth, sugar consumption and ethanol production. The yeast had an production ethanol average of 2.5 g / L and yield (Ye / s) 0.12 g / g, showing that they have the ability to produce ethanol from xylose.

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.
