Concentration and characterization of microalgae proteins from Chlorella pyrenoidosa
(Springer Open, 2016-03-26)
Background: Many methods are available for the concentration of proteins; however, most are not easily scalable due to costs, the need of specialized instruments and skilled workers or are very time-consuming. Three-phase ...
Methane emissions and estimates of ruminal fermentation parameters in beef cattle fed different dietary concentrate levels
Using sorghum silage, the effect of roughage/concentrate ratios was evaluated on nutrient intake, digestibility, ruminal parameters and methane production by beef cattle. Three treatments (0, 30 and 60% of concentrate in ...
Concentrations of Cu, Fe, Mn, and Zn in tropical soils amended with sewage sludge and composted sewage sludge
Sewage sludge may be used as an agricultural fertilizer, but the practice has been criticized because sludge may contain trace elements and pathogens. The aim of this study was to compare the effectiveness of total and ...
Determination of Cu, Ni and Pb in Aqueous Medium by FAAS after Pre-Concentration on 2-Aminothiazole Modified Silica Gel
This work describes the synthesis and characterization of 2-aminothiazole modified silica gel (SiAT), and the results of a study of the adsorption and pre-concentration (in batch and using a flow-injection system coupled ...
Diffusion phenomena of the oxygen and nitrogen in niobium by mechanical spectroscopy
The short-range diffusion phenomenon (Snoek Effect) was investigated by mechanical spectroscopy measurements between 300 K and 650 K, in a polycrystalline niobium sample, containing oxygen and nitrogen, using a torsion ...
Intraspecific allometry of haematological parameters in Basilichthys australis
Allometry of haematological parameters (haematocrit, erythrocyte number, mean cell volume and haemoglobin concentration) of Basilichthys australis, suggested that small individuals and juveniles had larger red blood cells, ...
