Activated carbons of resorcinol-formaldehyde aerogels (AC-RFA) were prepared and mixed with multiwall carbon nanotubes (MWCNTs) with various ratios.Samples were characterized by different techniques.The novelty of the study is in evaluating the effect of uniformity of carbon nanocomposites on their performance for the adsorption of CH4 and CO2 gase
NifA protein activates transcription of nitrogen fixation operons by the alternative sigma54 holoenzyme form of RNA polymerase.This protein binds Kitchen Knife to a well-defined upstream activator sequence (UAS) located at the -200/-100 position of nif promoters with the consensus motif TGT-N10-ACA.NifA of Azospirillum brasilense was purified in th
Background: The endemic vector-borne diseases transmitted by tsetse and ticks impose heavy burdens on the livestock keepers in Africa.Applying deltamethrin to the belly, legs, and ears of cattle offers a possibility of mitigating these losses at a cost affordable to livestock keepers.Although studies have quantified the impacts of individual diseas
ABSTRACT The Orinoco region, is the one with the largest area for forest development.Nonetheless, some of its soils are acid and characterized by low fertility levels, which has considerably limited plantation productivity.Therefore, this study aimed at assessing the effects of soil fertilizing and liming by using phosphorus and potassium on 34-mon
