Parameters on silage sorghum
Todos os textos, informa??es e resultados apresentados s?o de inteira responsabilidade dos autores.O Brasil, devido ? sua vasta extens?o territorial, associado ao clima predominantemente tropical, destaca-se no
contexto mundial como uma das grandes pot?ncias para a produ??o animal. Essa caracter?stica do clima ainda
permite a exist?ncia de uma grande diversidade de plantas forrageiras, de elevado potencial de produ??o por
?rea. No entanto, a estacionalidade na produ??o de forragem tem sido apontada como um dos fatores que mais
contribui para a baixa produtividade dos rebanhos. O processo de ensilagem serve como alternativa para suprir a
demanda alimentar no per?odo de estacionalidade. O sorgo, devido a sua boa qualidade qualitativa e quantitativa
segue como uma cultura em potencial para a produ??o de silagem.The Brazil due to its vast size, coupled with the predominantly tropical climate, stands out on the world stage as
one of the great powers for animal production. This characteristic climate still allows for a wide variety of forage
plants, high potential for production per area. However, seasonality in forage production has been identified as
one of the factors that contributes to the low productivity of livestock. The ensiling process is an alternative to
meet the food demand in the seasonality period. The sorghum, due to its good qualitative and quantitative quality
remains as a potential crop to produce silage
Population Genetics of Trypanosoma evansi from Camel in the Sudan
Genetic variation of microsatellite loci is a widely used method for the analysis of population genetic structure of microorganisms. We have investigated genetic variation at 15 microsatellite loci of T. evansi isolated from camels in Sudan and Kenya to evaluate the genetic information partitioned within and between individuals and between sites. We detected a strong signal of isolation by distance across the area sampled. The results also indicate that either, and as expected, T. evansi is purely clonal and structured in small units at very local scales and that there are numerous allelic dropouts in the data, or that this species often sexually recombines without the need of the “normal” definitive host, the tsetse fly or as the recurrent immigration from sexually recombined T. brucei brucei. Though the first hypothesis is the most likely, discriminating between these two incompatible hypotheses will require further studies at much localized scales
Diferenças entre homens e mulheres na qualidade da dieta: estudo de base populacional em Campinas, São Paulo
Study of decays to the final state and evidence for the decay
A study of decays is performed for the first time
using data corresponding to an integrated luminosity of 3.0
collected by the LHCb experiment in collisions at centre-of-mass energies
of and TeV. Evidence for the decay
is reported with a significance of 4.0 standard deviations, resulting in the
measurement of

Measurement of the lifetime
Using a data set corresponding to an integrated luminosity of ,
collected by the LHCb experiment in collisions at centre-of-mass energies
of 7 and 8 TeV, the effective lifetime in the
decay mode, , is measured to be ps. Assuming
conservation, corresponds to the lifetime of the light
mass eigenstate. This is the first measurement of the effective
lifetime in this decay mode.Comment: All figures and tables, along with any supplementary material and
