The extraction and mass transfer process of soluble solids in Russian olive

In this paper, through the research of mass transfer mechanism of the extraction process of soluble solids (SS) in Russian olive, the kinetic model of concentration change for the SS with the solvent multiple B (mL/g), extraction temperature T (K) and extraction time t (h) during extraction process was established for the first time. Russian olive extract concentration values  (%) can be calculated in...

Short-term responses of shrub layer communities to dry season fires and tree thinning in semi-arid miombo woodlands of north-western Zimbabwe

  Short-term responses of shrub layer communities to dry season fires and tree-thinning were investigated in semi-arid miombo woodlands in North-western Zimbabwe. Fifty-four (54) plots, 50 x 50 m each, were demarcated at three miombo sites. Treatments applied were: no burn, no tree thinning; no burn, thinned; early burn, no thinning; early burn, thinned; late burn, no thinning; late burn, thinned. After three...

Testing of striga resistant composite maize varieties for response to two levels of nitrogen fertilizer up-take

  Trials were carried out using five composite maize varieties in a Striga lutea (Lour) endemic soil of Temidire-Eruwa, Oyo State, Nigeria, in 2004 and 2005. The composite maize varieties were tested under varied fertilizer types, nitrogen (N) concentrations and artificial striga infestation. The objective was to test these striga resistant maize varieties for yield and agronomic performance under the...
