Verificação da eficiência do modelo de Mohler na resposta do comportamento de vigas mistas de madeira e concreto

The aim of this research study was to evaluate the structural behaviour of the wood and concrete composite system for bridge decks with emphasis on the metal shear connectors. Experimental tests were performed on composite specimens and wood and concrete beams with a metallic connector system in an X position, using CS100900-type screws. All specimens and beams were submitted to static loads until failure in order to obtain the strength and stiffness of the connection system. The experimental results for the stiffness of the beams were compared with the analytical results obtained through the Mohler model, presenting good equivalence for service loads. The experimental results obtained demonstrate that the most significant damage in composite systems occurred in the connectors' areas.

Seleção de famílias e progênies de irmãos completos de cana-de-açúcar para atributos tecnológicos e de produção pelo método de REML/BLUP

The objective of this study was to assess families and highlight the superior progenies of sugarcane originating from 38 biparental crosses for the following attributes: tons of cane per hectare (TCH), tons of biomass per hectare (TBIOH), brix (% cane juice), fiber content, purity, pol and total recoverable sugar (TRS). The data were analyzed by mixed model REML / BLUP in the REML (Restricted Maximum Likelihood) allowed us to estimate genetic parameters and BLUP (best linear unbiased prediction) to predict the additive and genotypic values. The best family for the attributes TCH and TBIOH was 41, whose parents are cultivars IACSP022019 x CTC9. In individual selection for TCH, the plant number 3 of Block 2, the crossing 78, showed the best results. To TBIOH the plant number 33, Block 1, family 41, showed the best results. Families 40, 41, 43, 68, 69, 79, 91, 92 and 147, were higher for the variables brix, pol, purity, and ATR, where as 85 families, 147, 148, 149, 161, 163, 177, 178, 179, and 183 were higher for fiber. The family 147 whose parents are IACSP042286 x IACSP963055, showed three progenies ranked among the top ten for both brix, and for fiber, which identifies the combination as a potential source of progenies for bioenergy production.

Reporting social behaviours of mixed-species troops formed by Callithrix jacchus and Callithrix penicillata (Primate, Callitrichidae)

In New World primates, mixed-species troops have been reported. Here, we analysed the performance of affiliative and agonistic behaviours of Callithrix jacchus and Callithrix penicillata living in mixed groups. For this purpose, we recorded the interaction of the individuals from two groups located in Bauru city, in the state of Sao Paulo (Brazil). Our data show that in both groups, affiliative behaviours appeared more frequently than agonistic ones. We concluded that there is cohesion inside the mixed-species troops observed. We suggest that a deeper knowledge about the social behaviour of mixed-species troop species certainly may be useful in projects linked with the management of the impact caused by them.

Distribution, composition and seasonality of aquatic birds in the Nhecolandia sub-region of South Pantanal, Brazil

Despite remarkable significance of Pantanal for the conservation of aquatic birds, the status of their populations, the spatiotemporal patterns of distribution and habitat use and structure of communities are little known. Thus, we studied three aquatic environments (Negro river, bays and salines) from 2007 to 2009 in the Nhecolandia Pantanal to verify the distribution and composition of aquatic birds and also if there is significant seasonal influence on these aspects. We adopted the transect method (288 hours of sampling) and recorded 135 species (7.834 individuals). The Negro river showed the highest diversity, while the salines the lowest. The similarity of aquatic bird communities was higher between bays and salines, followed by Negro river and bays and lower between salines and Negro river. The equidistribution is more variable in the salines and more stable in the Negro river. The environments strongly differ from each other in aquatic bird composition in space (habitat use and distribution) and time (seasonal water fluctuations). The diversity of bird community in the dry season varies significantly in the salines, followed by the bays and more stable in the Negro river. The Negro river, regardless of large annual amplitude of flow, is more seasonally stable since its riparian vegetation is continuous (not isolated) and constant. These aspects provide better conditions to stay all year, contributing to decrease the seasonal nomadic tendencies of aquatic birds. Finally, all these data provide strong arguments to the preservation of all phytophysiognomies in the Nhecolandia sub-region of Pantanal, but with special attention to the salines widely used by many flocks of aquatic birds (mainly in the dry season) and migrant and/or rare species restricted to this habitat.

Resposta crônica e aguda da glicemia a um protocolo de treinamento misto para melhora da saúde de diabéticos tipo 2

The objective of the research was to evaluate the effect of a training program of physical exercises mixed (aerobic / anaerobic conditioning circuit-break with active), including exercises, walking, weight training and Swiss ball, caused about possible changes in their metabolic system, as changes acute and chronic, individuals bearers of DM2. The methodology used is a model of experimented design of pretest and post-test applied to the group. The blood glucose levels were analyzed in fasting pre-test and post-test, and capillary glycemia in three periods of physical exercise: pre, during and post training, and the statistical processing done by the use of Statistical Software for PC-For SPSS ® Windows ®, V. 12.0 .. With the result has been a drop in the values significant glucometers between 6 weeks of training, with a negative delta average of 68 mg / dl. Furthermore, similar results were also found variations in the daily glycemic between the moments before and after the training session acute. Thus we find that, regardless of the biological mechanism responsible, the program mixed aerobic and anaerobic conditioning circuit-break with active was effective in reducing and controlling chronic and acute glycemic of subjects type 2 diabetic.

Efeitos do treinamento misto na promoção da saúde e sua interferência no perfil lipidêmico em indivíduos diabéticos tipo 2

Diabetes is a chronic disease that currently affects 171 million individuals approximately worldwide, with projection to reach 366 million people in 2030, increasing the prevalence of 2.8% in 2000 to 4.4%. The dyslipidemia is certainly one of the associated metabolic alterations most important, if we consider the main cause of death in Diabetes - the cardiovascular disease (CVD). One of the prevention and help factors in the Diabetes treatment and in the fall of associated complications is the physical exercise, which contributes to a better life quality to the diabetic. The main objective of the work was to evaluate the effect of a mixed physical exercises training program (aerobic/anaerobic with pause-active), including walking exercises, weightlifting and swiss ball, about possible changes in the blood lipid profile of adult individuals type 2 diabetics. The methodology used an experimental model of pre-test and post-test applied to the group. The data were first analyzed in a descriptive way for the normalization and the elaboration of averages and sample diversions. The sample was subdivided in two moments, being one pre and other post then weeks of training. After these procedures, the results of the values of the lipidic profile and glycemia were compared between the pairs pre and post training (test T Student, pair data), non-parametric. With the study, we can conclude that in despite of the low uptake of participants in the search, for reasons already cited, and the great age difference between them, the found results were partially satisfactory, because we achieved significant changes only in the glycemic variables, but we suggest future studies in the molds here proposed.
