From the estimation of the mass balance model, which can also be classified as “black box” model, it is possible to infer the impact of management on the system considered. This study aimed to evaluate water pollution generated by wastewater from a polyculture system of tilapia and shrimp and discuss the management employee and their relation to the quality of the effluent released. It used a pond measuring 1500 m2, average depth 1.6 meters, where 12 cages of 1 m3 populated with tilapia juveniles were installed 33 days after the shrimps’ population. The tilapia juveniles were distributed in densities from 200 to 400 fish per cubic meter, reaching the density of 2.4 fish per square meter within the total pond area. Shrimp post-larvae were released outside the cages within the pond area in a density of 3.3 organisms per square meter. Total density considering fish and shrimps was of 5.7 organisms per square meter in the pond area. Water samples were taken weekly in affluent and effluent of the pond (January-August/2009). The mass balance model was calculated from the difference between the estimated load for the output and input of the pond. The average flow rate was 4.46 L/s. The average loads nitrogen was 0.072 Kg/day (affluent) and 0.179 Kg/day (effluent) and phosphorus 0.0136 Kg/day (affluent) and 0.031 Kg/day (effluent). The mass balance resulted in mean values of 0.11 ± 0.06 Kg/day for total nitrogen and 0.017 ± 0.010 Kg/day for total phosphorus indicating that the system exported nutrients. The use of Best Management Practices (BMP) likes better feed and water management as a way to minimize nutrient export.

Abstract: studies have shown a progressive variation between the childhood and adolescence periods. variables such as age, weight, vitamin/hormone intake, the environment and soccer training may interfere in the knee alignment. objective: a- to compare the knee alignment in soccer and non-soccer practitioners, and b- to determine associations between this alignment and anthropometric and neuromotor variables. methods: the intercondylar (ic) and intermalleolar (im) distances were measured in centimeters in 128 male aged from 14-17 years, soccer practitioners (n=65) and non-practitioners (n=63). the anthropometric variables measured were: body weight and height, whereas the neuromotor variables included agility and speed. results: soccer players revealed a greater degree of genu varum (ic) than non-soccer players in all ages, but just in 14, 17 years-old and total group (all ages together) these differences were statistically significant (p< .05). genu valgum (im) tended to be less remarkable in soccer players than in non-soccer players in all ages; however, significant differences were observed only in 17 years and total group (p< .05). the ic distances in soccer players correlated (p< .05) with agility (r= .-27), weight (r= .-27); while im distances correlated (p< .05) with weight(r=.26). conclusion: soccer players showed more remarkable genu varum than the non-soccer players. there was a significant association between degrees of varus and valgum with body weight and agility. such fact deserves further investigation in order to explain this interesting correlation. present findings support the hypothesis that soccer leads to greater varus and/or this sport naturally selects subjects with a certain degree of varus.

Abstract: the efficiency of the concentric tubes internal-loop airlift reactor depends on the hydrodynamic conditions that affect oxygen transfer to the biofilm. this work studied the effects of the relation between diameters of the tubes and of the carrier (sand) concentration on the global oxygen transfer coefficient (kla). the tests - in 2,6 m high reactors with 250 mm external diameter and 100, 125, 150 and 200 mm internal diameters - were performed with air flow taxes up to 2,500 l.h-1 and sand concentrations up to 150 g.l-1. the kla increased slightly for 30 g.l-1 and decreased for higher concentrations, in accordance with related data for similar conditions. a model for kla in biphasic medium was fitted embracing all the external/internal area relationships tested, based on the reduction of the liquid phase transfer coefficient and the bubble diameter ratio with increasing air flow rates.

Abstract: the use of renewable energy sources, like solar, wind and biomass is rapidly increasing in recent years, with solar radiation being a particularly abundant energy source over northeast brazil. thus, the proper quantitative knowledge of the incoming solar radiation is of great importance for energy generation planning in brazil, serving as basis for developing future projects of photovoltaic power plants and solar energy exploration. this work presents a methodology for mapping the incoming solar radiation at ground level on northeast brazil, using a mesoscale atmospheric model (regional atmospheric modeling system - rams), calibrated and validated using the automatic surface stations network data from the ceará state foundation for meteorology and water resources (funda??o cearense de meteorologia e recursos hídricos- funceme). the results showed that the model presents systematic errors, overestimating surface radiation, but, after a proper statistical corrections, using a relationship between the model-predicted cloud fraction and the observed radiation at ground level and the estimated at the top of the atmosphere, a 0.92 correlation value, with a confidence interval of 13,5 w/m2, is obtained for monthly data. using this methodology, an estimated 215 w/m2 annual average incoming solar radiation over ceará is found (maximum in october: 260 w/m2).

Abstract: This research was carried out with the aim to evaluate the risks to health of the population in the consumption of raw milk sold in Itapetinga City, State of Bahia, in Brazil. Thirty samples obtained from three sale points (10 of each point) were submitted the following analyses: determination of the Most Probable Number (MPN) of 35°C coliforms and 45°C coliforms, research of Escherichia coli, Staphylococcus aureus count (CFU) and research of Salmonella. The experiment was conducted in randomized design with 10 repetitions. There wasn’t significant difference between the three sales points evaluated in the averages of S. aureus, 45°C coliforms and 35°C coliforms. All the samples were contaminated with 45°C coliforms and 35°C coliforms, in numbers that varied from 1,5x103 to 2,4x105 and 1,5x103 to 9,3x104 NMP/mL, respectively. The presence of E.coli was confirmed in four samples. The S. aureus count varied from 2,5x102 to 2x106. Regarding to research of Salmonella, were verified cultures with positive reaction into triple sugar iron and Lysine iron agars, in 93,3% of the samples, suggestive of bacteria belonged to that genus. The results of these analyses indicated that the sold of raw milk poses risks to the health of the population, besides this is an illegal practice in cities that have milk processing plants.
