Undoped and Sn, Ni-doped nanostructured ZnO thin films were deposited on glass substrates using a successive ionic layer adsorption and reaction (SILAR) method at room temperature. The SILAR deposited zinc oxide films have been rapid photothermal processing (RPP) at various temperatures to study the effect of annealing on the sensing properties. Structural, electrical and sensing properties wer...

On the basis of a statistical analysis of an alignment of the amino acid sequences, a new superfamily of metalloendopeptidases is proposed, consisting of human insulinase, Escherichia coli protease III and mitochondrial processing endopeptidases from Saccharomyces and Neurospora. These enzymes do not contain the 'HEXXH' consensus sequence found in all previously recognized zinc metalloendopepti...

The retroviral integrase (IN) protein is essential for integration of retroviral DNA into the host cell genome. To identify functional domains within the protein and to assess the importance of conserved residues, we performed site-directed mutagenesis of HIV-1 IN and analyzed the mutants in vitro for IN-mediated activities: 3' processing (att site-specific nuclease activity), strand transfer (...

BACKGROUND Several studies witnessed that prenatal zinc deficiency (ZD) predisposes to diverse pregnancy complications. However, scientific evidences on the determinants of prenatal ZD are scanty and inconclusive. The purpose of the present study was to assess the prevalence and determinants of prenatal ZD in Sidama zone, Southern Ethiopia. METHODS A community based, cross-sectional study was...

SYNOPSIS To conserve fresh water resources and comply with environmental regulations, DRDGOLD, a South African gold producer re-treating surface tailings, has transitioned to fully closed circulation system. Consequently, the accumulation of contaminants, as well addition reagents, led changes in composition that have compromised leach performance overall recovery. A two-sample t-test confirmed...
