Soil acidity in the humid forest zones of Cameroon is one of the major constraints to agricultural productivity.This study was carried out to assess the rhizobial communities of two acidic soils; with aluminum toxicity (Nkoemvone) and manganese toxicity (Nkolbisson) for their potential to improve soil fertility in Cameroon.These two soils were Trai
Sun et al.(2012) proposed a modified non-hydrostatic model (MNH), in which the left-hand side of the continuity equation is multiplied by a parameter δ (4≤δ≤16 in the article) to suppress high-frequency acoustic waves.They showed that the MNH allows a longer time step than the original non-hydrostatic model (NH).The MNH
Natural selection is widely noted to drive divergence of phenotypic traits.Predation pressure can facilitate morphological divergence, for example the evolution of both cryptic and conspicuous coloration in animals.In this context Dendrobatid frogs have been used to study evolutionary forces inducing diversity in protective coloration.The polytypic
Ag Q10+ TIME RESTORE coated microgroove with extreme large aspect-ratio of 500:1 was fabricated on p-GaN capping layer to investigate the coupling behavior between quantum wells and surface plasmon in highly spatial resolution.Significant photoluminescence enhancement was observed when the distance between Ag film and QWs was reduced from 220 nm to
Background: Oral Lichen Planus is a chronic inflammatory mucosal disease, presenting in various clinical forms.Both antigen-specific and non-specific mechanisms involved in the pathogenesis of OLP.Apoptosis or programmed-cell death is a physiological process essential for the normal development and maintenance of homeostasis in many organisms.Fas i
