Avaliação do efeito da inclinação e umidade antecedente na qualidade e quantidade das parcelas escoadas, percoladas e armazenadas em telhado verde extensivo

This study investigated the effect of slope and antecedent soil moisture on the water depth stored and percolated on extensive green roofs built in pilot scale. For this purpose, slopes of 10, 20 and 30% were investigated. Moisture was measured before and after each test in order to determine the differential moisture (∆U). The experimental runoff and percolated flow were analyzed by varying moisture and slope. Apparent color and turbidity were measured on runoff and percolated flow for each one of the modules. The results yielded that for the slopes of 10% the smaller values of runoff was obtained (average of 1,01% ± 0,7%). For the others slopes (20% and 30%), the runoffs were around 35% ± 15%. The sum of runoff and percolated water results in 77% (average) for slope of 10% and 80% for 20% and 30%. The slope and moisture have explained 87% of data for retained water and 81% for runoff. For percolated flow the inverse trend was observed. The retained water was 11,6±1,4mm for the module with 10% of slope, around 10,0±1,2 mm for the module with 20% of slope, and about 9,5±1,1 mm for the module with 30%. The results pointed out that both slope and antecedent moisture are crucial for runoff reduction and for material transportation.

Estudo hidrodinâmico quali-quantitativo de uma unidade de flotação por ar dissolvido (FAD): o efeito do dispositivo de coleta de água flotada

The main article aim was to investigate the collecting system of a dissolved air flotation (DAF) unit in pilot scale. Referring to the collecting system position, two options were analyzed: (i) top manifold and (ii) bottom manifold, pipes or plates. Qualitative and quantitative essays were performed, as image and stimulusresponse tests, respectively. The results of the essays standardized were adjusted by N-continuous stirred tank reactors in series and theoretical models of dispersion (low and high). The bottom manifold (plates with orifices) was more appropriate. The results pointed out that the N-continuous stirred tank reactors in series model was more adequate to describe the hydrodynamic behavior of the DAF unit.

Efeito do benzoato de estradiol na recuperação de oócitos, embriões e nos parâmetros hematológicos de cadelas recém acasaladas

We investigated estradiol benzoate effects on oocytes/embryos recovery rate and the influence of this drug on the hematopoietic system. Twenty four bitches were divided in two groups, Group I, 12 females that received a single shot of estradiol benzoate, 0.2 mg/kg intramuscularly, between 2 and 7 days after the date of the last mismating or insemination and, Group II (control), 12 bitches that received 0.2 ml/kg of oily diluent, in corresponding dates. The bitches were ovary-hysterectomized and the uterus/oviduct were isolated and flushed with a PBS, heparin and polyvinyl alcohol solution. Oocytes and embryos were quantified and classified according to their stage of development. Blood counts were performed on M1 (before drug administration), M2 (15 days after drug administration) and M3 (40 days after drug administration). Pearson correlation coefficient was used to analyze the variable retrieval structures, while Fisher exact test was used for the analysis of embryonic viability. ANOVA was used to analyze repeated measurements and Tukey test for hematological parameters. All tests were performed at 5% significance level. The recovery rate of total structures in group I was lower (22.88%) than group II (65.85%). A lower embryo recovery (ratio 3: 52) rate and a greater number of degenerated structures (ratio 11: 1) were observed in group I. Hematological parameters showed significant difference in erythrocytes, hematocrit and hemoglobin concentrations 15 days after drug administration and difference in leukocytes concentration 40 days after using the medication in bitches of group I, however, at the end of the experiment all bitches had blood counts considered normal.
