Época de sobressemeadura de gramíneas anuais de inverno e de verão no capim-Tifton 85: produção e composição botânica

The experiment was conducted at UNESP-Jaboticabal during the 2001-2002 winter-spring-summer periods to evaluate the herbage mass, botanical composition, dry matter production of mix pastures, and leaf: sheat-stem ration of Tifton 85 or overseeding with annual winter or summer species. The treatments were: pearl millet (Pennisetum americanum (L.) Leeke) plus bristeal oat (Avena strigosa Schreb); sorghum sudan grass (Sorghum bicolor (L.) Moench x Sorghum sudanense (Piper) Stapf) (SS AG2501 C) plus bristeal oat, overseeded on Tifton 85 area on 06/19/02/04, or 07/02/02, and Tifton 85, conducted in a randomized block design. The AG2501 contributed with a small participation in the botanical composition and the presence of millet in the experiment was not observed. Highest herbage mass at first and second evaluations related to first seeding time was 63% higher compared to the second seeding time. The herbage mass were similar he production in the other evaluations were similar. on the second seeding time, it was observed highest oat species in relation to the first seeding time. The leaf: sheat-stem ration decreased during the experiment due to the pasture botanical composition changes.

Molecular epidemiology of virulent Rhodococcus equi from foals in Brazil: virulence plasmids of 85-kb type I, 87-kb type I, and a new variant, 87-kb type III

We investigated the prevalence of virulent Rhodococcus equi in clinical isolates from 41 foals (19 sporadic and seven endemic cases) in Brazil between 1991 and 2003. of the 41 virulent isolates, six contained an 85-kb type I plasmid, 33 contained an 87-kb type I plasmid, both of which have been found in isolates from the Americas, and the remaining two contained a new variant, which did not display the EcoRI, EcoT221 and BamHI digestion patterns of the 11 representative plasmids already reported (85-kb types I-IV; 87-kb types I and II; 90-kb types I-V). We tentatively designated the new variant as the '87-kb type III' plasmid, because its BamHI digestion pattern is similar to that of the 87-kb type I plasmid. This is the first report of the molecular epidemiology surveillance of virulent R. equi in clinical isolates from Brazilian foals. (C) 2004 Elsevier Ltd. All rights reserved.

Electronic and structural properties of the (10(1)over-bar0) and (11(2)over-bar0) ZnO surfaces

The structural and electronic properties of ZnO (10 (1) over bar0) and (11 (2) over bar0) surfaces were investigated by means of density functional theory applied to periodic calculations at B3LYP level. The stability and relaxation effects for both surfaces were analyzed. The electronic and energy band properties were discussed on the basis of band structure as well as density of states. There is a significant relaxation in the (10 (1) over bar0) as compared to the (11 (2) over bar0) terminated surfaces. The calculated direct gap is 3.09, 2.85, and 3.09 eV for bulk, (10 (1) over bar0), and (11 (2) over bar0) surfaces, respectively. The band structures for both surfaces are very similar.

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.
