The purpose of the present study was to analyze the visual control of braking a bicycle when the cyclist is surprised by an obstacle in his way. According to Lee (1976), visually controlled braking based on time to collision information utilizes the optic variables tau and its first derivative in time, tau-dot, to initiating the braking action and regulating its intensity. Seven young adults performed a bicycle braking task in curvilinear trajectory under distinct velocity (high, medium, and low) and uncertainty (certainty and uncertainty) conditions. Results showed that, independently of velocity and uncertainty levels, participants utilized tau and tau-dot to initiating and regulating the braking action, avoiding collision with the obstacle. Cognitive, attentional, and other psychological factors resulting from both increased velocity and uncertainty were not capable of altering the use of time to collision information, corroborating the tested hypothesis

A new family of direct current (DC) to DC converters based on a zero current switching pulse width modulated (ZCS-PWM) soft commutation cell is presented. This ZCS-PWM cell is consists of two transistors, two diodes, two inductors and one capacitor; and provides zero voltage turn-on to the diodes, a zero-current turn-on and a zero-current zero-voltage turn-off to the transistors. In addition, a new commutation cell in a new ZCS-PWM boost rectifier is developed, obtaining a structure with power factor near the unity, high efficiency at wide load range and low total harmonic distortion in the input current.

Currently, responsible ownership of pets has been widely discussed. In the past, they were brought to our society and it is our duty nowadays to establish this relationship between man and animal. This study aimed at evaluating the level of knowledge of elderly dog owners about responsible ownership with emphasis on control of canine visceral leishmaniasis and at the same time make them aware of the precautions to be taken. An individual questionnaire on the subject was applied to 68 elderly people. They all belong to Nossa Senhora Aparecida Village, located on the suburb of Araçatuba-SP. Along with the interview, veterinary students advised them on the control of canine visceral leishmaniasis, the importance of sterilization in cats and dogs and the responsible ownership, with distribution of informative leaflets. Fecal samples from dogs were collected by the owners and they were sent to the Laboratory of Parasitology and Parasitic Diseases at Odontology Faculty at Araçatuba UNESP to be processed through the Willis-Mollay technique. Anthelmintic were acquired in the project and donated for the treatment of animals tested positive. 56.25% (63/112) out of the total number of dogs examined were females, aged between one and ten years. Only 32.14% (36/112) had access to the streets, 90.18% (101/112) were not castrated and 58% (65/112) were mixed breed (SRD). Among the owners, 88.24% (60/68) did not know what zoonosis is and 14.71% (10/68) were not aware what leishmaniasis is. Regarding the researched animals, 62.50% (70/112) had ectoparasites (fleas and ticks). It was also observed that 67.86% (76/112) of dogs had been dewormed, but in 59.82% (36/112) of cases, the intervals between these processes were irregular. For females, 85.71% (54/63) had no prevention heat and it was noted that 19.51% (8 / 41) had already given birth, had dystocia. With these data we can confirm the lack of information by these elderly and the need to establish community awareness and continued programs.

In this study, we compared the production cost of summer corn growing in soils treated with industrial fertilizer with those grown treated with sewage sludge. Corn was cultivated on reduced tillage treatment during 2002/2003 in an Oxisol area of 0.0625 hec. The field trial with industrial fertilizer was conducted following related guidelines for the state of Sao Paulo. The application of sewage sludge to the soil was at the rate of 10 t.ha-1. Calculations were based on market prices for the abovementioned years. In addition to lower environmental impact, results indicate economic cost advantages associated with the use of sewage sludge.
