Changes in Health-related Parameters Associated with Sports Performance Enhancement Drugs.
(Thieme Gruppe, 2022-12-02)
The purpose of this study was to evaluate changes in health-related parameters caused by the administration of anabolic-androgenic steroids and fat-burning drugs during a 6-month competition preparation period. The ...
Smallholder agriculture in African dryland agroecosystems has limited impact on trophic group composition, but affects arthropod provision of ecosystem services.
(Elsevier B.V., 2024-04-01)
Agricultural intensification is a major driver of biodiversity loss, but the majority of studies highlighting these threats come from industrialised agriculture in temperate countries of the global North. However, more ...
On a Class of finite rings
(Taylor & Francis, 2007-06-27)
In [7], Corbas determined all finite rings in which the product of any two zerodivisors is zero, and showed that they are of two types, one of characteristic p and the other of characteristic p2. The purpose of this paper ...
Unit groups of cube radical zero commutative completely primary finite rings
(Hindawi Publishing Corporation, 2005-07)
A completely primary finite ring is a ring R with identity 1 = 0 whose subset of all its zero divisors forms the unique maximal ideal J. Let R be a commutative completely primary finite ring with the unique maximal ideal ...
Cattle dung in aquatic habitats alters mosquito predatory biocontrol dynamics
(Elsevier, 2022-09)
Anthropogenic land use changes influence ecosystem functioning and may alter trophic interactions. Intensification of free–range pastoral farming could promote degradation of aquatic habitats, with nutrient inputs adversely ...
Assessment of γ-radiation levels and associated dose rates from surface soils in the eastern part of Botswana
(INDERSCIENCE Publishers, 2014)
This paper reports the γ-radiation levels of the naturally occurring 40K, 210Pb, 232Th and 226Ra and the anthropogenic 137Cs in the eastern part of Botswana so as to assess their possible dose impact to the members of the ...
Fuzzy Modeling for the Dynamics of Alcohol-Related Health Risks with Changing Behaviors via Cultural Beliefs.
(HINDAWI, 2020-07-13)
In this paper, we propose and analyze a fuzzy model for the health risk challenges associated with alcoholism. The fuzziness gets into the system by assuming uncertainty condition in the measure of influence of the risky ...
Wet deposition of 210Pb aerosols over two areas of contrasting topography
(Institute Of Physics Publishing Ltd, 2006-11-24)
Deposition fluxes of 210Pb on low and moderately high-elevation sites of Edinburgh (Scotland) and mid-Wales, respectively, have been measured. The excess 210Pb fluxes in moorland Edinburgh soils did not vary significantly ...
Correlations between Anthropometric Measurements and Sports Discipline Aptitude.
(MDPI, 2022-06-22)
Background: Sports specialization is required for the advancement of elite-level skills of a competitor. Therefore, this study attempted to assess the applicability of anthropometric measurements for a tailored selection ...
