Performance of cyclical and discrete movements executed in Fitts’ task simulated by computer Abstract This study compared the performance of cyclical and discrete movements in Fitts’ task simulated by a computer. Twenty male adults, between 25 and 30 years old, participated as volunteers in the study. The software Discrete Aiming Task (v.2.0) simulated the Fitts’ task, in the discrete and cyclical conditions, and provided the movement time (TM). It was manipulated 4 target widths and 3 distances between the targets to provide index of difficulties (ID) from 1 to 6 bits. The ANOVA TWO WAY, 3 (Conditions) x 6 (ID), with repeated measures in the last factor, compared the TM in the different conditions. Regression analysis verified the relationship between TM x ID. There were no significant differences between the conditions; the virtual environment and the mouse were used to explain such results. All movement conditions showed a straight relationship between TM x ID with R²>0.990. Therefore, Fitts’ law showed to be consistent, independently of the movement strategy performed.

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.
