Distribuição espacial dos incêndios em vegetação registrados pelo 2º Sub-Grupamento do Corpo de Bombeiros de Rio Claro/SP e o tempo atmosférico entre 2009 e 2013

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

Copépodes (Crustacea, Calanoida, Cyclopoida) planctônicos em reservatórios profundos e dendríticos: efeitos do tempo de residência e da idade de formação

Some ecological attributes of planktonic copepods (composition, diversity, abundance and its relations with limnological variables) were compared in two deep and dendritic reservoirs, 470km from each other, with contrasting water retention time (WRT) and ages of construction. Data were grouped from two different studies: samples were collected monthly between March/00 to February/01, on the Salto Caxias Reservoir (Iguaçu River), and tri-monthly between January/00 to October/01, on the Chavantes Reservoir (Paranapanema River). Eight species of Calanoida and six of Cyclopoida were identified in both reservoirs. The highest richness was observed in Salto Caxias (12 taxa) when compared with Chavantes (8 taxa), and six species were exclusive to Salto Caxias and two from Chavantes. Salto Caxias was studied one year after the construction, consequently with higher nutrients values in this period and showed generally high mean values of Copepoda (nauplius, copepodits and adults) than Chavantes, which is 38 years old. Some parameters as transparency, conductivity, turbidity and total nitrogen were significantly related with copepod abundance. New formation and sufficient long WRT could be an important cause for the highest richness of Calanoida and total abundance of individuals in Salto Caxias Reservoir.

Efeito do período pós-parto sobre a taxa de prenhez de vacas de corte submetidas à IATF (Inseminação Artificial em Tempo Fixo)

This work aimed to evaluate the influence of postpartum period (precocious - of 28 to 44 days and late - of 45 to 90 days) on the bovine pregnancy rate using fixed-time AI. For that, 678 cows were divided in two groups: precocious group (G-P, n=151) and late group (G-T, n=527). The animals received CIDR® + 2 mL of estradiol benzoate (BE) in the day zero (D0). After eight days (D8) the dispositive was removed and both groups received 2.5mL PGF2α, concurrent with PGF2α injection, they received either 1.5mL of eCG or temporary calf removal (RTB). In the next day (D9), the cows received 1 mL de BE and 24 hours later, the fixed-time AI was performed with Nelore bovine semen. The calves were returned to their mothers. The pregnancy rate was not different between the groups (p>0.05), G-P=40% and G-T=48%. The results indicate that females with less than 45 days of postpartum are able to hormone protocol of fixed-time IA.

Variação dimensional de tábuas de Eucalyptus grandis durante alguns níveis de tempo e temperatura de termorretificação

The objective of this study was evaluate the effects of retification® temperatures and times on thickness variation from Eucalyptus grandis timber. Boards from logs of 30-year-old Eucalyptus grandis trees, from São Paulo Forest Institute in Santa Barbara, Brazil, were thermally modified at 180ºC for 2.5 hours, at 200ºC for 3.0 hours and 200ºC for 4.0 hours. The results showed that: (1) the thermally modified wood at 200°C by 3.0 to 4.0 hours showed increased thickness between 0.698 mm and 0.874 mm due to the internal cracks, (2) the thermally modified wood at 180°C by 2.5 hours has a decreased from 0,177 mm in thickness and the absences of internal cracks.

Avaliação do tempo de resposta de um controlador de fluxo com DGPS submetido à variação de velocidade de voo em condições de voo simulado em laboratório

The application of pesticides is one of the most important steps in the agricultural production process. The spray volume can directly affect application success, and this parameter is directly dependent on the displacement speed of the sprayer. In conventional systems, the operator has to maintain a constant speed to ensure uniform application along the tracks. In order to improve over application quality and preserve levels of precision for applied doses; the use of electronic flow control systems allows for automatic adjustment of volume applied over the area when there is a change in velocity during application. The objective of this research was to study the response times of a flow controller with DGPS for aerial application subjected to variations of velocity in laboratory simulated flight conditions. For this purpose, a bench test has been developed including software for simulating DGPS signals, which was used to simulate different flight speeds and conditions. The results showed the average response time from the flow controller to a change in velocity to be between 6 and 20 seconds. Variations in total flow and the controller setting had a significant influence on response time with situations where there was interaction between the factors being evaluated. There was a tendency for better response times using a constant setting for the control algorithm other than that specified by the manufacturer. The flow controller presented an average error rates below 2% in all evaluated operating conditions, providing satisfactory accuracy in determining the output of product in different test situations.

Monitoramento do tempo de prensagem e do comportamento da temperatura através da espessura de painéis LVL (Laminated veneer lumber)

The aim of this study was to analyze the behavior of the flow of heat (temperature) through the thickness of panels LVL (Laminated veneer lumber) produced with phenol formaldehyde adhesive, in laboratorial and industrial scales. Experimental program was conducted with five LVL panels (three produced in laboratorial scale and two in industrial scale) with different arrangements of a mix of commercial veneers from tropical pinus from the south region of Sao Paulo State, Brazil, bonded using phenol formaldehyde adhesive. The temperature inside the panels during the pressing process was evaluated using thermocouples type T (cooper-constantan), installed mostly in the center of the glue lines and connected to a data acquisition system. The graphics of temperature as a function of the time showed a gradual increase of temperature up to pre-set values, remaining constant from them. The temperature reached at the center of the panels was adequate to promote the curing of the adhesive. These pre-set values were similar to the minimum values presented by other authors and manufacturers of these adhesives that affirm that temperatures above 100ºC at the center of laminated panels bonded with phenolic adhesives are sufficient to ensure proper cure of the resin. The time necessary for curing of the adhesives confirmed the validity of practical expressions provided by adhesive manufacturers.

Condutividade elétrica de sementes de camomila em resposta ao tempo de embebição e tamanho da amostra

Electrical conductivity has been proposed as a rapid test to evaluate seed vigor; however, few researches have emphasized methodologies to its use in seeds of medicinal plants, such as chamomile. The objective of the research was to evaluate the electrical conductivity of chamomile seeds affected by different imbibition times and sample size. The evaluations consisted of moisture content, germination and vigor (first count of germination) to seed initial characterization. Then, it was evaluated the electrical conductivity, affected by imbibition time (6, 12, 24 e 48 hours) and seed amount per sample (25, 50, 75, 100). The completely randomized design was used with four replications, arranged as a 4 x 4 factorial. Means were compared by the Tukey test at 5% of probability. It was concluded that the electrical conductivity of chamomile seeds is affected by the number of seeds per sample and imbibition time isolately.

Espaço, tempo e contradições: do Banco Nacional de Habitação ao Programa Minha Casa, Minha Vida em Presidente Prudente/SP

The housing issue in Brazil is'nt a recent problem and has been discussed, worked and questioned in the institutional framework, especially with regard to the critical considerations on the topic and urban problems involved. We as milestones in the Brazilian housing policy the National Housing Bank - BNH, 1964, the height of the military regime in Brazil, and the Minha Casa, Minha Vida, in 2009. Both have questions that approach and distance themselves regarding changes in the Brazilian housing policy, where we have the emergence of new forms of knowledge production and housing consumption. Thus we have a number of advances in ways of acquiring social housing, even at different times, it is characterized as capitalist forms of this issue. Thus the spatial process of housing developments arising from these programs reflect the change in space - time that they lay down, turning the urban space of the cities in this case the city of Presidente Prudente / SP

O espaço e o tempo feminino num dia qualquer: Belém 1960

Embora até hoje incipiente, não se pode dizer que o cinema paraense inexista. Alguns filmes realizados têm apresentado esparsas demonstrações, por vezes corajosas, de cineastas conterrâneos esforçados em usar a linguagem das imagens para captar aspectos documentais e/ ou ficcionais da sociedade, em épocas variadas. Libero Luxardo, paulista de Sorocaba, radicado em Belém desde a década de 40, insere-se entre os que já tentaram fazer cinema no Pará. Com uma obra premiada e clássica (Alma do Brasil - A Retirada da Laguna/ Mato Grosso/ 1931), pode ser visto competindo com alguns cineastas da sua época. Introduziu-se no meio paraense através da profissão que abraçara no sul, realizando documentários. Os filmes de ficção vieram depois, mas os dois gêneros usaram como background, a místico-exótica Amazônia. Uma de suas primeiras iniciativas cinematográficas para fixar-se no Pará foi Amanhã Nos Encontraremos, filme inacabado realizado na década de 40. Na segunda Interventoria de Magalhães Barata, o cineasta procurou registrar as benfeitorias governamentais dessa fase populista da política paraense. Entre os dados recolhidos da imprensa deste período, há notícias sobre os projetos a serem desenvolvidos por ele. Um outro dado muito significativo é dado pelo pesquisador Alfredo Wagner sobre a existência, na Região do Arari, de um caboclo que teria sido ator de filmes de Luxardo. A cinebiografia mais recente do cineasta aponta os seguintes filmes: Um Dia Qualquer (1962), Marajó, Barreira do Mar (1964), Um Diamante e Cinco Balas (1966) e Brutos Inocentes (1974). Da fase partidária e política, ressalta-se o documentário O Enterro de Magalhães Barata (1959), entre os inúmeros que realizou ao registrar as obras oficiais do governo baratista. O resgate histórico da passagem de Libero Luxardo pelo Pará está merecendo a atenção do pesquisador de cinema. Por ora, meu interesse em contextualizar sua obra deve-se a um tópico instigativo a ser desenvolvido: qual o olhar de Libero sobre as mulheres paraenses da década de 60 no filme Um Dia Qualquer? O tema pretende recobrir uma fase do cinema paraense, momento em que as mudanças culturais e sociais estão fazendo-se no mundo. Objetiva pensar também, nestes cem anos de cinema, as contribuições a ele dadas pela cultura paraense.
