Organic material decomposition and nutrient dynamics in a mulch system enriched...

The new techniques proposed for agriculture in the Amazon region include rotational fallow systems enriched with leguminous trees and the replacement of biomass burning by mulching. Decomposition and nutrient release from mulch were studied using fine-mesh litterbags with five different leguminous species and the natural fallow vegetation as control. Samples from each treatment were analyzed for total C, N, P, ...

Early sirolimus use with cyclosporine elimination does not induce progressive p...

Proteinuria has been reported in several papers after conversion from calcineurin inhibitors to Sirolimus (SRL), but this complication has not been analyzed in randomized clinical trials using de novo SRL. It is not known whether de novo use of SRL is a risk factor for proteinuria. We analyzed a series of patients included in a big multicenter randomized trial (RMR trial) corresponding to all patients in Spain ...

Migração sísmica 2-D pré-empilhamento em profundidade com operadores de extrapo...

Três métodos de migração 2-D pré-empilhamento em profundidade usando operadores de extrapolação "split-step" foram desenvolvidos e testados em dados sísmicos ordenados em famílias de tiro comum. No primeiro método, chamado de migração "split-step" simultâneo (SS-S), a migração é realizada simultaneamente para as fontes e receptores usando-se operadores de extrapolação do tipo "split-step". Os dados registrados ...
