Aedes aegypti proliferation in stormwater retained in Best Management Practices

The present study aimed to evaluate the risk of Aedes aegypti proliferation in structures used in compensatory techniques for urban drainage (Best Management PracticesBMPs). These drainage structures are utilised to reduce flood peaks due to surface runoff, and they have been used in many countries. However, many of these structures have been designed to keep water surfaces exposed for a certain period of time, depending on the type of project. Exposed water surfaces may become an ideal environment for A. aegypti proliferation in tropical and subtropical areas where the rainy season occurs during the summer. Thus, data regarding the mosquito life cycle, consecutive rainfall pattern and emptying time of these structures were collected. A comparison of these data led to the evaluation of the associated risk of A. aegypti proliferation in BMP structures. The risk of mosquito proliferation ranged from 1.1% to 3.3%, depending on the rainfall pattern, A. aegypti life cycle phase and BMP activity.

Evolução diurna e anual da frequência das coberturas de céu em Botucatu/SP

This work presents an analysis of the pattern variation of the sky conditions in Botucatu/SP. The classification was based on the clarness index KT. It was used in the classification a database of global solar irradiance in the horizontal, measured at Radiometric Station of UNESP in Botucatu (latitude 22.85°S, longitude 48.43°W, altitude 786 m) from 1996 to 2005. We analyzed the variations in frequency, during the photoperiod and over the year, of the sky conditions: I - Cloudy (KT < 0.35); II - party cloudy with dominance for the diffuse (0.35 < 0.55 < KT)) III - party cloudy with dominance for the clear (0.55 < KT < 0.65) and IV - clear (KT > 0.65). The frequency of sky conditions I and II are higher during the rainy season of the year and in hours close to sunrise and sunset. And it is lower during the dry season an in hours near noon, in wich there is a predominance of sky conditions III and IV. The monthly hourly frequency of sky condition I ranged from 46,91% of the photoperiod in January to 25.27% in August. And the frequency monthly daily ranged from nine days in January to three days in August. To the sky condition IV, the frequency monthly hourly ranged from 38.81% of the photoperiod in August to 18.17% im January. And the frequency monthly daily ranged from 17 days in August to three days in January.

Aplicação de doses de vinhaça sob desenvolvimento vegetativo de pastagem degradada e propriedades físicas do solo

The experiment was conducted in the experimental field of the University of GoiásUEG, UNU Ipameri - GO with the objective of evaluating the effect of different doses of vinasse on the vegetative development of degraded pasture and soil physical properties in two seasons. The pasture used in the experiment was in a state of degradation, and had eight years of formation. The experimental design was randomized blocks consisted of eight treatments and four blocks, totaling 32 experimental units. We evaluated the following soil physical properties: density the soil, particle density, total porosity, infiltration velocity, soil water. We also evaluated the following parameters of vegetative development of grassland: green and dry mass of shoots, effective depth of the root system, the grass height. The results were submitted to analysis of variance at 5% significance level and after we performed regression testing. The vinasse promoted significant effect on all parameters related to vegetative development of both grazing during the rainy season as in the dry. In this case, a model that best fit the dataset vegetative pasture was quadratic. It appeared that the vinasse different doses did not cause changes in the physical properties of the soil.
