Corpos intrusivos básicos na coluna sedimentar Permo-Carbonífera no vale do rio Corumbataí

As rochas intrusivas básicas associadas a Formação Serra Geral na porção sul do município de Rio Claro e norte de Piracicaba configuram geometrias na forma de diques e soleiras. Estes corpos estão associados à uma parte da Bacia Sedimentar do Paraná que foi deformada por eventos tectônico que resultaram em trends preferencias NW-SE, condicionando a estratigrafia, a intrusão e geometria dos corpos de diabásio e formação da estrutura domática do alto de Pitanga. Os corpos intrusivos tem em sua maioria a forma de soleiras e em menor quantidade a forma de diques. A compreensão destes corpos é importante para o entendimento da estratigrafia da área conhecida como domo de Pitanga na região de Rio e Piracicaba

As técnicas de agricultura tradicional em combinação com propostas e práticas de sistemas agroflorestais: consensos possíveis ao desenvolvimento sustentável da Reserva de Desenvolvimento Sustentável Quilombos de Barra do Turvo, Vale do Ribeira (SP)

O presente estudo teve como objetivo analisar questões sociais e econômicas do cotidiano de quatro comunidades quilombola (Cedro, Pedra Preta, Ribeirão Grande e Terra Seca) residentes da Reserva de Desenvolvimento Sustentável Quilombos de Barra do Turvo (Vale do Ribeira/SP), e levantar o debate acerca da questão da luta pelo reconhecimento da posse da terra frente à saída dos mais jovens da comunidade para as grandes cidades. Através dos dados coletados por meio de levantamento bibliográfico a respeito do tema e entrevistas semiestruturadas com representantes das famílias das quatro comunidades, foi possível discorrer a respeito da problemática da saída dos jovens, que afeta diretamente o futuro dessas comunidades tradicionais, bem como a sugestão de alternativas que visando geração de renda para essas famílias e a inserção e o futuro estabelecimento desses jovens no cotidiano das comunidades. Os resultados deste trabalho mostram que esses quilombolas, bem como seus antepassados, formam comunidades essencialmente rurais e agrícolas, com dinâmica fortemente ligada ao meio natural circundante. Quanto às suas práticas agrícolas, as famílias se dividem em dois grupos: os praticantes da agricultura tradicional, também chamada de “coivara”, e a agroecologia, com Sistemas Agroflorestais bem estabelecidos, onde os agricultores são organizados através de uma cooperativa agroflorestal. Essa divisão agrícola, como mostrado na pesquisa, tem reflexo direto na organização social e econômica das comunidades, bem como no processo de preservação do patrimônio cultural desses grupos. A pesquisa apontou ainda para um grande êxodo dos indivíduos mais jovens das quatro comunidades rumo aos grandes centros urbanos, pela falta de interesse destes na cultural local, ou pela busca por empregos regulares, levantando o questionamento sobre a preservação da cultura e do território quilombola de Barra do Turvo

Avaliação da qualidade da atenção ao parto nos colegiados de gestão regional Cuesta Botucatu e Vale do Jurumirim

The humanization of childbirth implies the understanding of this event as an important experience, and requires the redefinition of human relationships from the review of the assistance project, the understanding of pregnant women condition and human rights. To evaluate child birth assistance using a score that was developed by Botucatu Cuesta Regional Management and Jurumirim Valley Collegiates. This is an epidemiological, descriptive study that is inserted in the field of evaluation of services, programs or health projects. The data has been obtained by direct observation of deliveries, emphasizing the humane care. Results: Approximately one third of the women gave birth in a tertiary hospital (34.1%) and it was their first babies (33%).24.8% of the women received prenatal care in high-risk services. 67.1% of the births were normal, and 84.7% had no companions in the delivery room. In 47.1% of the cases the delivery was performed by obstetrician who used anesthesia in 44.7% and episiotomy in 48.2% of the deliveries. More than half of the newborns were attended by the pediatrician in the delivery room and had a delivery graph completed. Although the present study shows that 67.1% of the births were normal, caesarean rate can be considered excessive, as the WHO points out that c-sections above 15% are unlikely to be justifiable. It is important to emphasize that the Ministry of Health has to have a commitment with all women to promote safe motherhood, even in cases when the pregnancy involves a risk for both the mother and the fetus. It is noteworthy that the created score allowed us to assess variables related to the humanization of childbirth and only average and quite similar situations among the three services were evidenced. We hope that with this study, managers and professionals that work in this area can be subsidized in order to offer effective humane assistance and quality service in the delivery

Determinação da temperatura para inativação da urease em amostras de casca e farelo de soja

s not degraded in the rumen but destroy ureasis. Soybean meal is one of the protein ingredients commonly used in formulations of animal feeds. In the diets of monogastric bran has high protein content provided by a greater separation of soybean hulls. For the ruminant protein value of the meal is lower with the inclusion of soybean hulls to reduce the level of protein. With the increased consumption of meal high protein, due to increases in production of pigs and poultry in recent years, increasing the availability of soybean hulls on the market, this is because soybean hulls is little understood in the feeding of monogastric . In this context, the main objective of this study was to determine the times and temperatures needed to ensure the effective inactivation of ureasis present in the bran and soybean hulls. According to the assessments, to make the determination of temperatures and times required for the inactivation of ureasis present in the bran and soybean hulls are 170 º C and 25 minutes for soybean meal and 140 ° C 10 minutes for soybean hulls, respectively

Aplicação do ciclo rankine orgânico alimentado termicamente pela queima da casca do arroz e resíduos de madeira

With the growing world energy demand mainly from developing countries like Brazil, Russia, India and China, the search for efficient sources of energy becomes a challenge for the coming years. Among the most widely used alternative sources, biomass is the one that grows in a more pronounced way. This study will assess the real possibility of having it as a heat source in an Organic Rankine Cycle, which employ heat transfer fluids as working fluids instead of water. From a regional data collection in agricultural production and their potential rice production and the resulting husk was defined as more appropriate. The availability of husks together with an amount of eucalyptus wood, provided by a company in the region on a monthly basis, were analyzed, and the low participation of the wood was discarded by the thermal contribution of little significance. Based on this, it was established the calorific value of fuel for thermodynamic calculations and the cycle to be used. It was then carried out the choice of working fluid from the literature and their availability in the library of software used for the simulations, the Engineering Equation Solver - ESS. The fluid most appropriate for the burning of biomass, Octamethyltrisiloxane (OMTS), was not included in the software and so the R227ea and R134a were selected. After the initial parameters modeling definition, as condensing temperature, efficiency and live steam conditions, the simulations were performed, and only the R227ea remained within the feasible thermodynamic and technological ranges. With this fluid the turbine power output was 265.7 [kW] for a scenario of 24 hours/day burning, 800.3 [kW] to biomass burning for 8 hours/day and 2134 [kW] for burning only 3 hours/day. The thermal efficiency of the cycle remained in the range of 6%, and for plants operating with the most... (Complete Abstract click eletronic access below)

Territorialização da empresa Vale S. A: populações atingidas e conflitos sócio-espaciais

The projects of the company Vale SA territorialization triggers a series of territorial determinations on local populations. This process denotes a situation of sociospatial conflicts between the affected people and the company, which occur in the material and symbolical scope. In the expansion of these conflicts is established the International Articulation of those Affected by Vale and the “Movimento de Soberania Popular Frente a Mineração” (MAM) which aims to promote communication and unification of the struggles between different social movements and populations on confrontation with the company. This project aims to examine how these conflicts are established in projects relating to mining operations in Brazil. The development starts from a mapping of the investments in the sector, identifying the major determinations territorial, the forms of organization of resistance, identifying who are the groups in conflict

Preparação e caracterização da casca de banana prata particulada para aplicação com reforço em compósito de matriz de PEAD

The waste, exaggerated and incorrect disposal of biomass are common practices in modern times where everything is disposable. However the growing concern with the nature and the environment compel man to give nobler destinations for these products through sustainability and recycling of waste. Banana peel is a residual biomass, which is not consumed. It generates tons of waste per week in São Paulo city. This trash is disposed in dumps and landfills, which could be reduced by using it as reinforcement in natural composites. The high density polyethylene (HDPE) is a polymer derived from the ethylene polymerization and is easily recycled. Which makes it a sustainable material. In the present work characteristics of the natural composite composed with banana peel and high-density polyethylene were studied. It was noted that removing the lignin present in the banana peel, the fiber introduces a significant improvement in thermal resistance. The preparation of composite was made with a ratio of 5% and 10% of reinforcement in comparison with polymeric matrix mass. Composites were thermally, mechanically and microscopically characterized. The addition of fiber in the polymer increased the mechanical strength of the composite. The fiber surface treatment with distilled water removed the amorphous material present in the fibers, improving significantly thermal stability and increasing crystallinity of the celullose. The addition of 5% fiber in mass to the polymer increased significantly the tensile strength and elasticity modulus for the composite. With 10% of fiber addiction there were also an improvement when compared with pure HDPE, but when compared with 5% composite the mechanical properties are slightly lower. This may be due to the fiber particle size, which are small and eventually become a hub of tension ... (Complete abstract click electronic access below)

Política e Ritual: a faina missionária beneditina entre os Makuxi no vale do Rio Branco

This paper deals with a reconstruction of the Benedictine missionary work in the Rio Branco valley (1909-1947), referenced to the relations established between the monks from the Monastery of São Bento do Rio de Janeiro and Macushi, people of Carib linguistic affiliation in the Guiana region. Such reconstitution reveals the tone of relations between the Indians and missionaries on the ritual production, seeking to interpret its possible meanings.

Memória ambiental, cultural e turismo no vale histórico do Rio Paraíba do Sul: design de uma pesquisa

This text is aimed at disseminating cultural and environmental wealth of a region little known of major tour operators - which is strongly marked by historical traditions, in a bucolic rural still and by the hospitality of its residents. The Historic Valley of Rio Paraíba do Sul, although located in the Rio - Sao Paulo road lives in the shadow of the remarkable progress of the industrial cities in the main Valley. This paper presents results of research that deepened the knowledge of this region, with notable findings from the standpoint of culture and tourism, regional and national history. Isolated by considerable geographical barriers, this region has two aspects: the rebirth of nature after the decline of coffee plantations, with ecological sanctuaries that can now point toward environmental sustainability, and the formation of a culture with two historical times - refinement inherited from the barons coffee, paradoxically linked to the rustic countryside and modernity derived of its proximity to major centers. The results presented here are part of exploratory research, but were presented at different events, emphasizing the baroque character of practices derived from these two historical times and tourist potential related to the “cultura tropeira” and to hospitality that marks this countryside.
