Screening for indigenous algae and optimisation of algal lipid yields for biodiesel production
The depletion of global energy supplies coupled with an ever increasing need for energy and the effects of global warming have warranted the search for alternate renewable sources of fuel such as biodiesel. First generation ...
Linear electrostatic waves in two-temperature electron–positron plasmas
(Cambridge University Press, 2012-05-04)
Linear electrostatic waves in a magnetized four-component, two- temperature electron–positron plasma are investigated, with the hot species having the Boltzmann density distribution and the dynamics of cooler species ...
Improvement of ethanol production from sugarcane molasses through enhanced nutrient supplementation using Saccharomyces cerevisiae
(Academic Journals, 2012-03)
Saccharomyces cerevisiae as a yeast cream was utilized for alcoholic fermentation using sugar cane molasses. In the present study, fermentation was optimized for urea and yeast hydrolysate (YH) dosage and the combined ...
Nutritional status and dietary intake of adolescent girls in Mandlenkosi High School, Lindelani
Background: Assessing the nutritional status of adolescents could be a catalyst in addressing malnutrition at an early age and at a school level. Objectives: The study was conducted to examine the nutritional status and ...
Analysis of selected organic pollutants in water using various concentration techniques
Among persistent organic pollutants, chlorobenzenes are some of the most frequently encountered compounds in aqueous systems. These compounds can enter the environment via natural and anthropogenic sources, and are ...
Inﬂuence of alkyl group and temperature on thermophysical properties of carboxylic acid and their binary mixtures
(Elsevier B.V., 2014-06-30)
n this work, volumetric, acoustic and refractive index methods have been used to study the interactions between carboxylic acids mixtures as a function of temperature and concentration. The density (r), sound velocity (u), ...
Interaction between high- and low-frequency waves
(Springer Verlag, 2013)
We outline models for the interaction between high- and low-frequency waves that arise in plasma physics and atmosphere/ocean dynamics. The original ideas are embodied in the Zakharov equations, which describe the interaction ...
Investigations of the bioprocess parameters for the production of hemicellulases by Thermomyces lanuginosus strains
The aim of this study was to evaluate T. lanuginosus for the production of hemicellulases, its yield enhancement using mutagenesis and application of a selected xylanase on bagasse pupl to assess the improvement of pulp ...
