Apesar de pouco explorado, a prática de atividade física promove redução da Pressão Intraocular (PIO). O objetivo foi verificar o efeito de diferentes tipos de exercício na PIO. Quinze voluntários foram submetidos a 3 sessões de 30min de exercícios resistidos (3 x 8 repetições a 80%1RM), aeróbio contínuo (60% da Frequência Cardíaca de Reserva [FCR]), aeróbio intervalado (2min a 50% alternando com 1min a 80% da FCR). PIO foi mensurada antes (M1), durante (M2-15min), imediatamente após a sessão (M3) e na recuperação (5min [R1] e 10min [R2]). Como procedimento estatístico foi utilizado ANOVA. Houve redução da PIO nas 3 sessões de exercício (M2 e M3). Na recuperação, PIO permaneceu reduzida após 5min (R1) em todos os modelos. Porém, aos 10min (R2) estava menor que M1 apenas na sessão de exercício intervalado. Os resultados sugerem que o exercício intervalado é mais efetivo que o contínuo e resistido na redução da PIO.

Estudos sugerem que a atividade física promove redução e contribui no controle da Pressão Intraocular (PIO). O objetivo foi verificar o efeito de diferentes exercícios na PIO. Quinze voluntários foram submetidos a 3 sessões de 30min de exercícios resistidos (3 x 8 repetições a 80%1RM), aeróbio contínuo (60% da Frequência Cardíaca de Reserva [FCR]), aeróbio intervalado (2min a 50% alternando com 1min a 80% da FCR). PIO foi mensurada antes (M1), durante (M2-15min), imediatamente após a sessão (M3) e na recuperação (5min [R1] e 10min [R2]). Adotou-se ANOVA para tratamento estatístico. Houve redução significativa da PIO nas 3 sessões de exercício (M2 e M3). Na recuperação, PIO permaneceu reduzida após 5min (R1) em todos os modelos. Porém, aos 10min (R2) estava menor que M1 apenas na sessão de exercício intervalado. Os resultados sugerem que o exercício intervalado pode ser mais efetivo que o contínuo e resistido na diminuição da PIO.

The aim of this study was to investigate the performance of an experimental rainwater treatment system for non-potable uses. Without the first-flush discharge it was expected to control the quality of captured rainwater and to minimize the rainwater by-pass caused by the first-flush strategy. A full-scale direct filtration unit was operated and a solution of natural corn starch was used as the primary coagulant. The color, turbidity e coliform efficiencies of the unit was analyzed based on filtration loads and the net water production was estimated. The results pointed out turbidity removal up to 70.8% and color removal up to 61.0%. The backwash of the filtering system was completed in 3 minutes at the rate of 1,440 m3/m2day with consumption of treated water from 0.5% to 2.2%, based on the potentially harvesting.

This study aims to clinically and macroscopically evaluate the adjuvant therapy with platelet-rich plasma in the form of eyedrops or clot, for corneal ulcers in dogs treated at the Veterinary Ophthalmology Service. We analyzed 20 eyes diagnosed with ulcerative keratitis, divided into two experimental groups. The eyedrop group (GC) was composed of eyes treated topically with eyedrops of autologous plateletrich plasma (PRP), and the clot group (GT) was composed of eyes treated with a platelet-rich clot and covered with a third eyelid for retention of the clot. The groups were evaluated by clinical and macroscopic analysis and by the analysis of epithelial defect reduction, at different times, at three, five, ten, 15 and 30 days, except for the third day in GT. The coverage of the third eyelid was removed on the fifth day. In both groups the inflammation signs reduced, there was an improvement in ocular sensibility and proper repair of epithelial defect. All GT eyes and 70% GC eyes showed complete healing on the fifth day, the remainder of GC completed healing on the tenth day. PRP in the form of eyedrops and clot is an excellent adjuvant therapy to be instituted in the clinical treatment for corneal ulcer in dogs, because it decreases the inflammatory signs and the ocular pain and it potentially assists in healing epithelial defects.

Agricultural mechanization improved the efficiency of field operations by providing an increase in crop production. The intensified mechanization, however, has led to higher energy use mainly in the area of fuel consumption. The objective of this study was to compare the fuel consumption of tractors using two different tire pressures for two different types of soil during tillage with irrigated cotton in semi-arid regions. These tests were performed at the Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona with a Case 4x2 TDA 88kW equipped with an autopilot system. The results showed lower fuel consumption using a tire pressure of 124 kPa on sandy clay loan soil.

Currently, the efficiency in field operations and the increased productivity of crops is only possible with the use of agricultural machinery and equipment. This intensification of mechanized activities in agriculture, however, led to higher energy costs on farms mainly in the fuel consumption of agricultural tractors. The objective was to compare the fuel consumption of a tractor on tillage operations for irrigated cotton in semi-arid region varying two tire inflation pressures. The tests were conducted in Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona using a 4x2 TDA Case tractor equipped with a 88kw autopilot system. The results showed lower values in the hourly fuel consumption by using the minimum tire inflation pressure of 124 kPa for all tillage equipment used.
