Endogenous retroviruses (ERVs), eukaryotic transposable elements, exist as proviruses in vertebrates including primates and contribute to genomic changes during the evolution of their host genomes. Many studies about ERVs have focused on the elements residing in the human genome but only a few studies have focused on the elements which exist in non-human primate genomes. In this study, we ident...

Abstract Background Artisanal gold mining has been one of the major contributors to soil pollution. These types have potential environmental implications and varying degrees health risk due agricultural product cultivation. The contamination level Pb in soils under cultivation by maize spinach from mines Abare, Dareta Bagega Anka local government Zamfara state was examined. Three levels depths ...

Abstract Voltage instability is a serious phenomenon that can occur in power system because of critical or stressed conditions. To prevent voltage collapse caused by such instability, accurate prediction necessary for planning and operation. This paper proposes novel index ( NCPI ) to assess the stability conditions lines. The effectiveness applicability proposed are investigated on IEEE 30-bus...

Let R be a ring and let I 6= R be an ideal of R. Then I is said to be a completely prime ideal of R if R/I is a domain and is said to be completely semiprime if R/I is a reduced ring. In this paper, we introduce a new class of rings known as completely prime ideal rings. We say that a ring R is a completely prime ideal ring (CPI-ring) if every prime ideal of R is completely prime. We say that a...

Heavy metal (HM) contamination and accumulation is a serious problem around the world due to the toxicity, abundant sources, non-biodegradable properties, and accumulative behaviour of HMs. The degree of soil HM contamination in China, especially in the Yangtze River Delta, is prominent. In this study, 1822 pairs of soil and crop samples at corresponding locations were collected from the southe...

The importance of sustainable development has been widely recognized by people, society, governments, and the business world. Green information technology (IT) has therefore become one of the latest considerations to improve the environmental sustainability of a business. Yet, as important as this term is, it is being used in so many different ways that it might lose meaning altogether. It is i...

The use and implementation of public open street Closed Circuit Television (CCTV) surveillance systems in Central Business Districts (CBDs) in South Africa solely for the purpose of crime control (reducing street crime) or crime prevention (deterrence) has in South Africa been a relatively new intervention within the broader context of crime prevention programmes. One of the drawbacks to its im...
