Variação da distribuição do diâmetro eritrocitário e do volume corpuscular médio em cães anêmicos

The anisocytosis is a hematologic finding that is routinely evaluated from the mean corpuscular volume (MCV) and erythrocyte morphology in assessment of blood smears. The present study tested the hypothesis that the coefficient of variation of the red cell distribution width (RDW-CV - Red Cell Distribution Width) is a more sensitive parameter in the evaluation of hematologic anisocytosis, considering different levels of anemia in dogs and reticulocytosis. Blood counts of 102 anemic dogs and 353 control dogs made by automated hematology counter. The anemic animals were grouped according to the degree of anemia (mild, moderate and severe) and also as medullary response by manual reticulocyte count (none, weak, moderate and strong). The RDW-CV was different to the animal groups with moderate and severe anemia, which were higher, compared to the control group and mild anemia. The highest average value of RDW-CV (14.45%) occurred in patients with severe anemia. In the control group had higher MCV value that anemic animals , this may be due to a mixed population of erythrocytes in that group of animals. However, there wasn’t difference in MCV between different degrees of anemia and reticulocytosis. Therefore, the RDW is a more sensitive indicator anisocytosis than VCM and its value is directly proportional to the degree of anemia and reticulocytosis; when combined, the sensitivity for detection of anisocytosis in anemic dogs is greater. The use of reference values established by the clinical laboratory itself is mighty important.

Indicadores antropométricos do estado nutricional entre idosas praticantes e não praticantes de exercício físico na zona norte de São José do Rio Preto-SP

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profi le of the elderly who also used walking as a means of getting around.

Força muscular e massa corpórea de ratos Wistar

The use of rats in studies that seek to monitor the effects of physical exercise is fairly common, even in works that make use of overload. However, the correct determination of the training load is critical to success of studies. Thus, with the objective of verifying the correlation of total body mass of the rats with their respective strength, and the correlation of the 1RM test with test repetitions, 40 rats, 90 days old and weighing average 0,49 pounds underwent a program of adaptation to the water and then were subjected to tests to determine the maximal and submaximal loads. After measuring the total body mass and maximal and submaximal strenght, it was possible to observe directly proportional relationship between maximum strenght and total body mass of 0.97 (P ≤ 0.01), being the maximum muscle strength equivalent to 109% of the total body mass. Between muscle strength and mass submaximal muscle strength was also found direct correlation between the variables, allowing to conclude that the submaximal strength test and total body mass are effective tools in determining the training load of rats.

Microinversor integrado ao módulo fotovoltaico para sistemas conectados à rede elétrica utilizando controlador ressonante

This paper shows the modeling and control of a single-phase full-bridge inverter with high-frequency transformer that may be used as part of a two-stage converter with transformerless DC-DC side or as a single-stage converter (simple DC-AC converter) for grid-connected PV applications. The inverter is modeled in order to obtain a small-signal transfer function used to design the P+Resonant current controller. A highfrequency step-up transformer results in reduced voltage switches and better efficiency compared with converters in which the transformer is used on the DC-DC side. Simulations and experimental results with a 200 W prototype are shown. 1

Demanda energética de máquinas agrícolas na implantação da cultura do sorgo forrageiro

Forage sorghum can be grown in areas and environmental conditions dry and warm, where the productivity of other forage plants can often be uneconomical. The soil disturbance can be made only on the lines of planting (direct seeding) or entirely from the area for seeding (conventional tillage), as plowing, harrowing, subsoiling and chiseling (minimum tillage). The displacement speed ideal for planting is one in which the groove is opened and closed without removing the over-ground, allowing the distribution of seed spacing and depth constant. The experiment was conducted in a soil classified as Typic Oxisol at Lageado Experimental Farm, Faculty of Agronomic Sciences, UNESP, Botucatu campus. This study aimed to evaluate the response of sorghum in four forward speeds (3, 5, 6 and 9 km h-1) and four systems of soil management: SD (direct seeding), GP (harrow + sowing), LPG (disc harrow and two light disking + sowing) and CR (scarification and seeding). Data was subjected to analysis of variance in a factorial 4 x 4 and a randomized block design with split plots. The following parameters were determined: average speed, average strength of the drawbar, the average power drawbar, theoretical field capacity of the tractor-equipment, fuel consumption per hour. For the conditions under which the experiment was conducted, it was concluded that the hourly fuel consumption was not influenced by tillage systems and was inversely proportional to the increase of speed work, and that the change of speed in the sowing operation did not provide additional the values of average traction force on the bar of the tractor-planter.
