Arsenic Oxidation Assisted by Carbon-based Catalysts in Dynamic and Continuous Conditions
… on oxidation efficiency. Rapid small-scale continuous column testing method was employed to simulate dynamic and continuous operations. The process residence time, pH and initial arsenic concentration are demonstrated to be the most crucial operational parameters that have significant …

Thermal Analysis Based Design of Hollow Shaft for Improved Cooling of Induction Motors
… temperature of 100℃ under different motor power conditions. Three hollow shaft design cases were studied at steady state conditions to evaluate their heat transfer performance and surface temperature to meet the goals of the study. This includes the design of a counterflow, counterflow with fins, …

The interdependent regulation of photosynthesis and the circadian clock in wheat
… in leaf temperature could be measured in continuous light (Chapter 3). This led to the design of a low-cost leaf temperature measuring device which uses thermocouples directly attached to the surface of leaves to measure temperature. To determine the effect of the circadian clock on …

Production of Bacterial Cellulose Using Low-cost Media
… used in the bioreactors: batch, fed-batch and continuous. The morphology of the BC depended on the growth conditions. Thin sheets were formed in stationary cultures and pellicles were formed in agitated cultures. The scanning electron microscope micrographs showed that BC produced under static …

Hatchdate distributions and growth rates of anchovy (Engraulis encrasicolus) in the Southern Benguela ecosystem
… die one hand. and the prevailing environmental conditions on the other. Sub-samples were chosen proportional to the length-frequency distributions at each stratum or station at each survey. Otoliths of 193 specimens (14-70 mm standard length, SL) from the March survey and 80 specimens (52-114 mm …

Produzione di H2 e CH4 da frazioni biodegradabili di rifiuti urbani e da siero lattiero-caseario
… null H2 production, identification of suitable conditions to harvest specific fermentative bacteria and/or inhibit the H2-consuming biomass is mandatory. Achieving optimal and stable H2 generation while keeping treatment costs low and producing an effluent suitable for further treatment, is …

An investigation into the precipitation of Fe(III) oxyhydroxides in lime neutralization processes
… R) of 3, from the Ca(OH)2 solution. The reaction conditions were such that no gypsum was precipitated. The experiments to investigate the effect of molar ratios were conducted at OH/Fe molar ratios ranging from 3/1 (R = 3), 2.5/1 (R = 2.5) and 2/1 (R = 2) whilst the [Fe(III)] in the feed was kept …
