Noise Data Visualization and Identification Project

This project aims to produce a space and time map of noise levels within a city using data gathered from sensors, with the goal of identifying noise hot spots and quiet zones. It also includes a noise identification module that attempts to classify reported sound data

Effect of the substitution of soybean meal by dehydrated yeast (Saccharomyces cerevisiae) as protein source in diets to weaned piglets on the weight of digestive tract organs and activity of pancreatic enzymes

The effects of the substitution of crude protein (CP) of soybean meal (SBM) by CP of dehydrated yeast Spray dry (DYSD) on the weight and development of the digestive organs and the activities of pancreatic enzymes were evaluated in this research. For this purpose 60 twenty one days old weaned pigs were distributed according to randomized blocks design with a factorial arrangement 5x4 (5 levels of substitution: 0, 25, 50, 75 and 100 % of the SBM crude protein by DYSD crude protein in the diet x 4 periods of time: 0, 4, 8 and 12 days post weaning). The DYSD did not have any influence on daily weight gain, weight of stomach and daily feed intake (DFI), however the intestinal weight increased quadraticaly and the weight of pancreas decreased linearly. The activity of tripsin did not change, on the other hand lipase (measured as activity units/g pancreas) and amylase decreased in a quadratic and linear sequence respectively with de increase of DYSD in the diet. Evaluated the weaning periods, it may be concluded that a decrease in the protein content and the growth rate of pancreas, associated with a low DFI found in the first days of post weaning, they may be the causes of shortening in the synthesis of pancreatic enzymes

Effect of the substitution of soybean meal by dehydrated yeast (Saccharomyces cerevisiae) as a protein source in diets for weanling piglets on the intestinal digestive enzymes

The effects produced by the substitution of the crude protein (CP) of the soybean meal (SBM) by CP of the dehydrated yeast in "spray dry" (DYSD) on the morphology of the small intestine mucosa and the activity of the intestinal digestive enzymes was studied. For this purpose, 60 weaned piglets twenty one days old were distributed according to a design of blocks at random with factorial arrangement 5x4 (5 substitution levels: 0, 25, 50, 75 and 100 % of SBM crude protein by DYSD crude protein in the diet x 4 periods of time: 0, 4, 8 and 12 days after the weaning). The DYSD in the diet only did cause a reduction of the intestinal villi size in the first segment of the small intestine, promote a lineally increase in the activity of the sacarase and maltase, and at the same time the dipeptidases showed a quadratic response

Immediate effects of photobiomodulation therapy combined with a static magnetic field on the subsequent performance: a preliminary randomized crossover triple-blinded placebo-controlled trial

There is evidence about the effects of photobiomodulation therapy (PBMT) alone and combined with a static magnetic field (PBMT-sMF) on skeletal muscle fatigue, physical performance and post-exercise recovery in different types of exercise protocols and sports activity. However, the effects of PBMT-sMF to improve the subsequent performance after a first set of exercises are unknown. Therefore, the aim of this study was to investigate the effects of PBMT-sMF, applied between two sets of exercises, on the subsequent physical performance. A randomized, crossover, triple-blinded (assessors, therapist, and volunteers), placebo-controlled trial was carried out. Healthy non-athlete male volunteers were randomized and treated with a single application of PBMT-sMF and placebo between two sets of an exercise protocol performed on isokinetic dynamometer. The order of interventions was randomized. The primary outcome was fatigue index and the secondary outcomes were total work, peak work, and blood lactate levels. Twelve volunteers were randomized and analyzed to each sequence. PBMT-sMF decreased the fatigue index compared to the placebo PBMT-sMF at second set of the exercise protocol (MD = -6.08, 95% CI -10.49 to -1.68). In addition, PBMT-sMF decreased the blood lactate levels post-intervention, and after the second set of the exercise protocol compared to placebo (p<0.05). There was no difference between PBMT-sMF and placebo in the remaining outcomes tested. Volunteers did not report adverse events. Our results suggest that PBMT-sMF is able to decrease skeletal muscle fatigue, accelerating post-exercise recovery and, consequently, increasing subsequent physical performance when applied between two sets of exercises.publishedVersio
