This study aimed to evaluate the quantity and fuel moisture content material deposited in planting of Tectona grandis Linn.F with 20 years in the municipality of Sinop - MT. In the study area were installed five plots of 1 m2 within which collected up all the material above ground. The collected material was separated and weighed according to their type (green or dry) and class (leaf, miscellaneous, and branches 7, 6 cm). 100 g were taken. material from each plot to determine the moisture content in the laboratory after drying in an oven at 75 ° C for 48 hours. The experimental design was completely randomized in a factorial 2x7 (Type X Class) in 5 repetitions, significant means were compared by Tukey at 5% probability. Found 23.2 t ha-1 of dry combustible material in the area. There was no green material because the light conditions caused the tops of planting. There was a significant difference in the amount of combustible material in each class. Classes leaves and miscellany excelled presenting 8.37 Mg ha-1 and 10.29 t ha-1, respectively. Due to the climatic conditions of the season collects a 65.82% moisture content of the material was found.

Hábitos alimentares de universitários apresentam-se na maioria das vezes inadequados, caracterizado pelo baixo consumo de frutas e verduras e alta ingestão de alimentos ricos em gorduras e açúcares. Dessa forma, este grupo apresenta um maior risco de contrair doenças crônicas não transmissíveis (DCNT). Diante disso, o propósito deste estudo foi avaliar os hábitos alimentares de estudantes universitários da UFS. Foram entrevistados, , 718 universitários dos cursos das áreas de exatas (300), humanas (180) e saúde (238), O instrumento utilizado para coleta de dados foi uma adaptação do questionário do Ministério da Saúde, além do da auto-referição do peso e da estatura. Os resultados mostraram que a maioria (69,6%) dos universitários encontrava-se eutróficos e 17,9% com excesso de peso (principalmente entre os homens, p

Incubation of sclareol with Rhizopus stolonifer affords in high yield a mixture of triols with 18-hydroxy-sclareol as the main component.

The spatial dynamics of criminal activities has been recently studied through statistical physics methods; however, models and results have been focusing on local scales (city level) and much less is known about these patterns at larger scales, e.g. at a country level. Here we report on a characterization of the spatial dynamics of the homicide crimes along the Brazilian territory using data from all cities in a period of more than thirty years. Our results show that the spatial correlation function in the per capita homicides decays exponentially with the distance between cities and that the characteristic correlation length displays an acute increasing trend in the latest years. We also investigate the formation of spatial clusters of cities via a percolation-like analysis, where clustering of cities and a phase-transition–like behavior describing the size of the largest cluster as a function of a homicide threshold are observed. This transition-like behavior presents evolutive features characterized by an increasing in the homicide threshold (where the transitions occur) and by a decreasing in the transition magnitudes (length of the jumps in the cluster size). We believe that our work sheds new light on the spatial patterns of criminal activities at large scales, which may contribute for better political decisions and resources allocation as well as opens new possibilities for modeling criminal activities by setting up fundamental empirical patterns at large scales.

In the present study, we investigate patterns in the postural sway that characterize the static balance in human beings. To measure the postural sway, sixteen healthy young subjects performed quiet stance tasks providing the center-of-pressure (COP) trajectories. From these trajectories, we obtained the COP velocities. We verified that the velocity distributions exhibit non-normal behavior and can be approximated by generalized Gaussians with fat tails. We also discuss possible implications of modeling COP velocity by using generalized Fokker-Planck equations related to Tsallis statistics and Richardson anomalous diffusion. [ABSTRACT FROM AUTHOR]
