Many fire occurrences in vegetation happen annually in the city of Rio Claro, causing material losses, environmental damage and discomfort to population. When identified the source, notes that the higher index is intentional, however, climatic factors such as wind speed, temperature, relative air humidity, rainfall, or even the local relief also affects in the spread and its devastating effects. Scientific studies that would assist the local community in the prevention and repression of them still are scarce. This way, the work has as objective contributes in the understanding of the relationship among the fire occurrences in vegetation registered (recorded) by Fire Department of Rio Claro/SP, and their relationships with the atmospheric time. To achieve this goal was made to build a database related to fires in vegetation during the years 2009-2013, and subsequently correlated with data of precipitation and relative humidity the air, provided by Center for Analysis and Planning Environmental (CEAPLA). The result identified the profile of the fires, the seasons of higher frequency, neighborhoods and districts with the highest number of records and correlate events with climatic factors that act in the ignition, propagation and control of fires in the Municipal district of Rio Claro/SP

This study aimed to generate a database related to the spatial distribution of hives and productivity of regional producers, through the Geographic Information System (GIS) using the Global Positioning System. To build the database of geographical information (GIS) software for processing of geo-referenced information was used. The microregion (4 municipalities and 54 beekeepers) shows concentrations (pockets) of beekeepers and hives in certain locations. Further studies are needed on the characteristics of the local flora for bees to infer about possible saturation of floral resources, since no differences were observed between honey production in apiaries isolated or inserted into the pockets. The GIS proved to be an efficient tool for monitoring the location and origin of regional production, and for planning the distribution of hives and apiaries and so, contribute to a better use of flora and improvement of productivity of the apiaries.

A introdução de espécies exóticas traz severas consequências para o ambiente, sendo a perda de diversidade a mais notável. Espécies exóticas podem competir por recursos com as espécies nativas, podendo assim causar a extinção de muitas espécies. A demografia e o padrão espacial de populações naturais também podem ser afetados pela presença de uma espécie invasora, o que pode levar a significativos efeitos para todo o ecossistema. Este trabalho teve por objetivo investigar o impacto causado na demografia e no padrão de distribuição espacial da palmeira Euterpe edulis pelo pisoteio e herbivoria do javaporco, resultado do cruzamento do Sus scrofa com o Sus scrofa domesticus. Esta palmeira tem especial importância para o ecossistema por ser considerada uma espécie-chave no ambiente, fornecendo alimento para muitas espécies. Foi feita uma parcela de 25 x 50m e contabilizados todos os indivíduos da palmeira presentes. Para avaliar a estrutura demográfica as plantas foram categorizadas em seis estádios de acordo com a altura: plântula, jovem I, jovem II, imaturo I, imaturo II e adulto. Para a distribuição espacial as plantas foram divididas em quatro estádios de acordo com o potencial impacto do javaporco e importância para o recrutamento: plântula, jovem, imaturo e adulto. Os dados foram coletados antes (2008) e depois (2014) da invasão do javaporco em um fragmento de mata estacional semidecídua no interior do Estado de São Paulo. A invasão do javaporco não afetou drasticamente a estrutura demográfica como um todo, mas houve uma redução considerável na proporção de plantas jovens I. Para avaliar os impactos na distribuição espacial usamos uma análise espacial de padrões de pontos univariada (entre plantas dentro de cada estádio) e bivariada (entre plantas de dois estádios). O javaporco não influenciou a distribuição espacial de plantas em cada estádio e nem as relações espaciais entre as plantas...

In order to diversify the global and national energy matrix and reduce harmful impacts on the environment caused by the emission of polluting gases into the atmosphere, the use of clean and renewable energy sources is presented as a good alternative. This work discusses the use of photovoltaic solar energy, a source that presents such characteristics. The photovoltaic system under study is the type distributed connected to the grid, in the residential segment. It is informed of its use in the global and national levels. They are also present their characteristics, electrical and electronic circuits that make up the equipment required for its operation and the design of a system to be installed in a residence

The pharmaceutical industry was consolidated in Brazil in the 1930s, and since then has become increasingly competitive. Therefore the implementation of the Toyota Production System, which aims to lean production, has become common among companies in the segment. The main efficiency indicator currently used is the Overall Equipment Effectiveness (OEE). This paper intends to, using the fuzzy model DEA-BCC, analyze the efficiency of the production lines of a pharmaceutical company in the Paraíba Valley, compare the values obtained by the model with those calculated by the OEE, identify the most sensitive machines to variation in the data input and develop a ranking of effectiveness between the consumer machinery. After the development, it is shown that the accuracy of the relationship between the two methods is approximately 57% and the line considered the most effective by the Toyota Production System is not the same as the one found by this paper

Considering the high competitivity in the market, the application of quantitative methods can assist in analyzing the efficiency of production facilities of areas of export and import processes of the chemical industry sector. In this sense, this work aims to apply the model GPDEA-BCC optimization in order to develop an analysis of the production units of this chemical industry. So, were chosen variables relevant to the process and elaborated a final comparison between the results obtained by the optimization tool and performance indexes provided by the company. These results indicated that some production units should be monitored more carefully because some of them had a low efficiency when analyzed with multi criteria
