Production of sheep grazing on nitrogen-fertilized tifton 85 grass in continuous stocking

Biomass and forage volume density and the performance and stocking rate of sheep on pastures with nitrogen-fertilized Tifton 85 and subjected to a continuous stocking system were evaluated. Four doses of nitrogen (0, 100, 200, and 400 kg ha-1 year), arranged in an experimental design with randomized blocks and four replications, were analyzed. Sixteen paddocks and Santa Inês sheep were used as test animals, coupled to crossbreed Santa Inês sheep as regulating animal stocking. Nitrogen-fertilized Tifton 85 pastures increased the amount of forage biomass and volume density which affected stocking rate and weight gain of sheep in continuous grazing. When pastures with Tifton 85 were administered in variable load continuous stocking, with grass kept at 15 cm, nitrogen fertilization up to 400 kg ha-1 year is recommended.

Estudo clínico comparativo entre sutura convencional e vaporização a laser de dióxido de carbono (CO2) em pele de ratos

The proposal of this study was to compare a wound healing between conventional suture and vaporization with CO2 laser in rats skin. ln such case 24 rats were utilized, making two longitudinal incisions in dorsum by scalpel. ln the left side incision the wound was sutured with nylon thread. ln the right side incision the wound were close by approach and vaporized with C02 laser, defocusing, 8 watts in continuous mode. The wound healing was followed by clinical photographic taking at the times: immediately after the procedure, 24 hours, 3, 7, 14, and 21 days. The results showed an early delay of reparation in healing vaporized in comparison with the sutured one, however occurred 21 days both repair tissue showed the same clinical characteristic. This results suggested that the C02 laser can be used by eventual substitute of suture.

Impacto de tempestade geomagnética na ionosfera e no posicionamento com GNSS: estudo de caso para 20 de novembro de 2003 na região brasileira

The goal of this paper is to analyze the influence of the intense geomagnetic storms in the ionosphere and GNSS (GPS) positioning. It was analyzed the effects of intense geomagnetic storm of November 20th 2003 using GPS data from RBMC (Brazilian Network for Continuous Monitoring) located in different sites in the Brazilian region and ionosphere global maps. While analyzing the results, it can be observed an increase in the electron density of the ionosphere in the regions near to the geomagnetic equator in the afternoon on the day of the storm. In the period after the sunset of the storm day, there is an increase in the density of free electrons and ionospheric irregularities in regions furthest from the geomagnetic equator, when compared to geomagnetically quiet days. When the positioning point is analyzed, it is observed high discrepancies values in planimetry and altimetry at the same position for periods of changes that occurred in the ionosphere, especially for the GPS stations located furthest from the geomagnetic equator in the period after the sunset Sun.
