The authors dealt with some hazardous elements, i.e. As, Cd, Co, Cr, Cu, Ni, Pb and Zn, contained in sands of the sandboxes localized in playgrounds of seven spas in southern Poland (CEE). The following determinations were made: the total contents of metals, the most mobile metals (water-leachable fraction) and the metals available to plants and organisms (CaCl2- and EDTA-extractable fractions)...

This work investigated the viability of a non-edible oil obtained from raphia africana in production biodiesel using novel heterogeneous catalyst derived turtle shells (Centrochelys sulcata). The study also proposed use acetone as co-solvent to enhance solubility reacting mixtures. were calcined at 900oC for 3hr, impregnated KOH improve its activity and then supported with activated carbon prod...

Background Human leukocyte antigen (HLA) gene is a highly polymorphic region. HLA typing is required to match patients and donors for transplantation; therefore, development of HLA registries is necessary for finding HLA match donors. HLA system is highly informative, and numerous studies have been conducted on HLA allele distribution in different populations. Methods In this study, 100 unrel...
