Análise sazonal e espacial da precipitação pluvial na bacia hidrográfica do rio Ivaí, Paraná

Climate variability and therefore the rainfall is often cited today, in times to speak of "global change", "global warming", "anthropogenic disasters," among other terms related to climate issues, which may cause floods and disasters that affect entire regions. In this sense, the seasonal rainfall and its extremes in the basin of Ivaí river, which has a drainage area of approximately 36 000 km2, covering a length of 680 km, located in the State of Paraná between coordinates 22 º 54'S 25 ° 44'S and 55 44'W to 52 º 42'W, were analyzed. Influence of rainfall for the man occupation is undeniably important, not less important is the role that this issue poses to the climate abiotic and biotic environment, because the dynamic relations between the fauna and flora is directly related to the availability of water in system (in this case, rain). The methodological procedures used during the research focused on statistical analysis of rainfall series daily, monthly and yearly, provided by the Superintendence of Water Resources Development and Environmental Protection Agency - SUDERHSA, an agency linked to the government of Parana. The analysis period chosen was from 1975 to 2005, with 38 stations for data collection, distributed evenly across the search area. The standard rainfall in the basin is explained mainly by convective processes in the summer (wet season) and front system causing more homogeneous rainfall over the basin (dry season). What is well marked is the occurrence of maximum rainfall in the years 1983 and 1997 (El Niño) and minimal in the years 1977, 1985 and 1988 (La Niña). Finally, although the study area have undergone a significant change in your landscape for over thirty years, this study indicates no significant interference in rainfall.

Relacionamento e coordenação da cadeia produtiva da mandioca no Noroeste do Paraná

The production of starch and cassava starch (Manihot esculenta) if has shown to an important business for the region the northwest of the Paraná, generating income and job for a significant agricultural producers. The production of the region is processed for industries at private capital and cooperatives of producers. The study involving agricultural producers and one of the most important cooperatives of the region (C-Vale) objectified to evaluate the relationships between cooperative and producers, and the mechanisms of coordination of the productive chain. The results had disclosed that the relationships are not harmonious, generating opportunism situations, high costs of transaction and diffidence in the operations between producers and cooperative. Also if it perceived a difficulty of coordination of the productive chain, due to lack of integration between the partners, what it affects the competitiveness and the efficiency of the sector.

Petrologia e geoquímica das rochas graníticas do maciço do Capão Bonito, SP

The granitic massif Capão Bonito is located in the southwest of the State of São Paulo and is associated with Neoproterozoic evolution of Central Mantiqueira Province. Its rocks outcrop along the edge of the Paraná Basin in a body with elongated shape whose major axis has a general NE-SW, covering an area of approximately 110km2. Occurs in intrusive epimetamorphic rocks of Votuverava Formation, Acungui Group and granitic rocks of the Três Córregos Complex and their placement is related to a brittle tectonics of NE-SW direction shear zones. In metasediments, when preserved from deformational features imposed by mylonitic deformation, preserve up textures and mineralogy of contact metamorphism with development of mineral in albite-epidote and hornblende hornfels facies. The Massif Capão Bonito consists of red syenogranites, holo-leucocratic with biotite and rare hornblende, medium to coarse inequigranulars and isotropic lightly mylonitic and / or cataclastic in marginal regions. Commercially are called Vermelho Capão Bonito and for export as Ruby Red Granite. Rocks belonging to the calcium-alkaline high potassium to shoshonitic series or the series subalkaline potassic and metaluminous to peraluminous character. The magmatism is compatible with granite type A, tardi-orogenic to anorogenic of intraplate environment, from the crust material with lower melting emplacement associated with correlated transtensive structure to shear zones in an extensional environment at the end of collisional event of Orogênese Ribeira. Metamorphism occurred in the region in the greenschist facies, low to medium, generating quartzites, phyllites, schists, and calcium-silicate metabasics

Análises energética e econômica da produção de leitões de produtores familiares do Oeste do Paraná

The present study aimed to analyze indicators of energy efficiency and economic production of piglets from family farmers in Paraná. We sought to determine possible differences in energy efficiencies and economic producers who manufactured rations on their property and those who bought rations Cooperative. The sample was obtained by accessibility (six producers who manufactured and six who bought rations) and not probabilistic, and the raw data were transformed into energy and economic units, and processed in electronic spreadsheets. The two production systems of piglets in the nursery phase, family farming, showed negative energy balance, with energy inputs higher than outputs. The two systems of rearing piglets showed no differences in energy efficiency, ie, they were not self-sufficient and needed to import energy sources from other systems. The indicators of economic efficiency of producers who buy rations as those who produce them in their properties were less than unity. Thus, most producers did not generate enough revenue to pay the costs in the short term and lost money.

Análise econômica da eficiência da produção de cana-de-açúcar de fornecedores do Estado do Paraná

The sugarcane industry has been important in the Brazilian economy since the colonial period. The search for alternative energy sources has gained more prominence, by offering a product generating clean energy. With the opening of the Brazilian economy, the sector has undergone transformations operating in a free market environment requiring greater efficiency and competitiveness of those involved in order to stay in business. This scenario is producer/supplier independent, and social aspects related to their stay in the market. Although its share in sugarcane production is smaller than the plant itself, it is still considerable having reached around 20% to 25% in 2008 by employing labor, also production factors had an important economic impact in the regions where they operate. Therefore, this study aimed to estimate the economic efficiency and production of independent sugarcane producers in the state of Paraná through the DEA model. The Data envelopment analysis (DEA) is a nonparametric technique that, using linear programming constructs production borders from production units that employ similar technological processes to transform inputs into outputs.The results showed that of the total surveyed, 13.56% had maximum efficiency (an efficiency score equal to 1). The average efficiency under variable returns to scale (BCC-DEA) was 0.71024. One can thus conclude that for the majority of the samples collected, it might be better use of available resources to the in order to obtain the economic efficiency of the production process.
