Techno-economic comparison and environmental impact assessment of a hybrid photovoltaic thermal solar system and a thermosiphon solar thermal hot water system with electric back up element, under Windhoek, Namibian conditions
… Energy Institute using measuring instruments coupled to the systems. Both TS-SWH and PVT systems have the same technical make up, but the PVT system has solar PV cells on its collector. The findings of this study are that global radiation plays a major role in the operation of both solar water …

rRNA Promoters as Targets for Transcription Factors: Structural and Functional Studies of PhERI and CarD
… that PhERI interacts with σA4 near the -35 element of all promoters, but blocks the binding of an additional RNA polymerase subunit, the α-CTD, to UP-element DNA sequences. PhERI therefore only inhibits RNA polymerase activity at promoters requiring UP-element activation, most notably the …

Ochrobactrum anthropi: a soil bacterium for the study of Brucella virulence
… the identified virulence genes are putative. Disruption of putative virulence genes and studying the consequent effect on attenuation in cell lines or mouse models is a widely used method. However, in most cases it is not apparent whether the mutated genes encode virulence factors or merely affect …

Control of The Master Virulence Regulatory Gene Atxa In Bacillus Anthracis
… Western blot analysis, the <em>cis</em>-acting elements and <em>trans</em>-acting factors involved in regulation of <em>atxA</em> in <em>B. anthracis </em>strains containing either both virulence plasmids, pXO1 and pXO2, or only one plasmid, pXO1, were studied. This work demonstrates that …
