Detrital nutrient content determines growth rate and elemental composition of bromeliad-dwelling insects
Seasonal patterns of organic matter stoichiometry along a mountain catchment
Organic matter (OM) nutrient content is expected to change as OM is transported from upstream forested reaches downstream to open land, and these changes could depend on seasonal patterns. The aim of this study was to ...
Ilustração da influência da razão de aquecimento nos resultados de termogravimetria
(Sociedade Brasileira de Química, 2000-02-01)
The effects of the heating rate on a TG curve of a sample have been widely discussed in the literature. This paper shows the influence of heating rate (beta) in thermogravimetry results when stoichiometry determinations ...
Assembly stoichiometry of bacterial selenocysteine synthase and SelC (tRNAsec)
(Elsevier BVAmsterdam, 2013-04)
In bacteria selenocysteyl-tRNAsec (SelC) is synthesized by selenocysteine synthase (SelA). Here we show by fluorescence anisotropy binding assays and electron microscopical symmetry analysis that the SelA-tRNAsec binding ...
Introduction to a Virtual Special Issue on ecological stoichiometry and global change
(Wiley Blackwell Publishing, Inc, 2012-11)
The determination of the stoichiometry of the mixed complex of vanadium with hydrogen peroxide and with 4-(2-Pyridilazo) Resorcinol
(Sociedade Brasileira de Química, 2000)
N and S concentration and stoichiometry in soybean during vegetative growth: Dynamics of indices for diagnosing the S status
(Elsevier Science, 2016-11)
Information regarding the pattern of sulphur (S) accumulation in shoots is scarce for field crops and few comprehensive analysis were performed on N:S stoichiometry. Particularly, the need to study the patterns of uptake, ...
Biodegradation of bisphenol A and its metabolic intermediates by activated sludge: Stoichiometry and kinetics analysis
Bisphenol A (BPA) has been described as a estrogenic compound. However, it is used in the production of polycarbonate, epoxy resins and other plastics. Mixed microbial cultures, such as activated sludge, have been proposed ...
