Research ArticleOpen accessEvery word in the titleBaseline Concentrations of 11 Elements as a Function of Land uses in Surface Soils of the Katangese Copperbelt Area (D.R. Congo)Martin T. Mpinda, Tresor N. Kisimba, Theodore M. Mwamba et al.The Katangese Copperbelt Area (KCA) located south-eastern of D.R. Congo presents high concentration of Metal Trace Elements (MTE) due to a rich natural geochemical background and intense mining activities. However, the lack of data on specific baseline concentrations makes it difficult to assess and monitor the environmental quality of soils in the region. In this study, 11 MTE were measured … …American Journal of Environmental Sciences, Vol. 17, Issue 6 · 3 Jan 2022 · 7,126 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Basic Elements of Life'sRaffaella Aversa, Victoria Petrescu, Antonio Apicella, Ion Tiberiu PetrescuThe four basic elements of life are: Oxygen, hydrogen, nitrogen and phosphorus. These four elements are found in abundance in both the human body and in animals. There are other elements that compose the human body, but the four we've highlighted participate in all life processes. Besides, these four elements make up ATP chains (molecule), which governs and controls the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 17 Dec 2016 · 121,931 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE EFFECTS OF ORAL ADMINISTRATION OF DIFFERENT DOSES OF HYDROALCOHOLIC EXTRACT OF SILYMARIN ON STATUS OF SERUM TRACE ELEMENTSJ. Sajedianfard, S. Nazifi, H. A. ShamsaeiIn this research, the effect of oral administration of different doses of hydroalcoholic extract of silymarin on the status of trace elements with antioxidant properties (Se, Cu, Zn, Mn and Fe) was studied. Fifty male rats were randomly used in five groups including healthy control group (treated by saline), diabetic control group (treated by saline) and three diabetic groups that … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 3 · 24 Oct 2014 · 6,644 accessesView PDFCite
