Inventories of fallout 210Pb and 137Cs radionuclides in moorland and woodland soils around Edinburgh urban area (UK)
(Elsevier, 2006)Inventories of fallout 210Pb and 137Cs have been measured in moorland and woodland soils around the Edinburgh urban area, using a high purity germanium detector. The 210Pb inventories in moorland soils were relatively ... -
Factors influencing ambient concentrations of 210Pb and 7Be over the city of Edinburgh (55.9°N, 03.2°W)
(Elsevier, 2006)Concentrations of 210Pb and 7Be in air were continuously monitored, using a high-volume air sampler and a high-resolution gamma-ray spectrometer, during the period of July 2002 to June 2003 at the University of Edinburgh ... -
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 ... -
Atmospheric transfer and deposition mechanisms of 210Pb aerosols onto forest Soils
(Springer Verlag, 2009-09)Activities of 210Pb carrier aerosols in an age-graded Sitka spruce conifer, three deciduous (oak, lime and sycamore) foliage and in rain and throughfall samples have been measured during the period of 2001–2002. The 210Pb ... -
Deposition rates of atmospheric particulates determined from 210Pb measurements in soils and air
(HARD Publishing, 2010)Deposition rates of atmospheric particles were determined using previously published 210Pb data in soils and air. The dry deposition velocities for moorland and woodland soils were 2.2±1.8 and 9±2 mm• s-1, respectively. ... -
Assessment of heavy metal pollution in soils along major roadside areas in Botswana
(Academic Journals, 2011-03)Assessment of heavy metal pollutants: Al, Co, Cu, Fe, Pb, Mn, Ni and Zn was conducted along major roadside soils of Botswana, lying between latitudes 18°S to 27°S and longitudes 20°E to 29°E using enrichment factor ratios ... -
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 ... -
Effect of Benzyladenine Plus Gibberellins and Gibberellic Acid on Yield and Yield Components of Cucumber (Cucumis sativus L. cv. ‘tempo’)
(Asian Network for Scientific Information, 2006)Two greenhouse trials were carried out to evaluate the effect of benzyladenine plus gibberellins (GA4+7) and gibberellic acid (GA3) on yield and yield components of cucumber. Gibberellic acid significantly increased leaf ... -
Allelopathic activity of sunflower (Helianthus annuus L.) on growth and nodulation of Bambara Groundnut (Vigna subterranea (L.) Verdc.)
(Asian Network for Scientific Information, 2007)Laboratory and greenhouse experiments were conducted to determine the allelopathic activity of sunflower (Helianthus annuus) on seed germination, seedling growth, flowering and nodulation of bambara groundnut (Vigna ... -
A retrospective study of the prevalence of bovine fasciolosis at major abattoirs in Botswana
(AOSIS, 2016-06-13)A retrospective study covering a period of ten years (2001–2010) was conducted using postmortem meat inspection records of the Department of Veterinary Services in Gaborone to determine the prevalence of bovine fasciolosis ... -
Influence of strain and egg size on the hatchability of indigenous tswana chicken eggs
(International Journal of Livestock Research, 2013-08-29)The objectives of this study were to find the influence of strain and egg size on the hatchability of indigenous Tswana chicken (ITC) eggs. In the first part of the study, a total of 240 eggs were collected from each of ... -
Comparative growth performance of cross-bred (50% Orpington: 25% Australorp: 25% Tswana) and pure-bred tswana chickens under an Intensive Management System
(Academic Journals, 2015)Indigenous Tswana chickens are well-adapted to local environmental conditions but exhibit slow growth rate. Exotic chickens are not well-adapted to local environmental conditions but exhibit rapid growth rate and high egg ... -
Semen characteristics of purebred naked neck tswana and black australorp x naked neck tswana crossbred chickens under an intensive management system in Botswana
(American Journal of Research Communication, 2016)Evaluation of semen quality is very important before selection of breeding cocks used for artificial insemination. The aim of this study was to characterize the semen parameters of Black Australorp x naked neck Tswana ... -
Growth performance of different strains of indigenous Tswana chickens under intensive management system
(Academic Journals, 2012-04-26)Indigenous Tswana chickens are traditionally kept under free range production system and their growth performance under an intensive management system have not been evaluated. The purpose of this study was therefore to ... -
Growth performance of Australorp x Tswana crossbred chickens under an intensive management system
(Asian Network for Scientific Information, 2013)Indigenous Tswana chickens are better adapted to prevailing environmental conditions and diseases than their exotic counterparts. They however exhibit slower growth rate and less mature final weight than their exotic ... -
A critical analysis of disease-associated DNA polymorphisms in the genes of cattle, goat, sheep, and pig
(Springer Verlag, 2008-04)Genetic variations through their effects on gene expression and protein function underlie disease susceptibility in farm animal species. The variations are in the form of single nucleotide polymorphisms, deletions/insertions ... -
A critical analysis of production-associated DNA polymorphisms in the genes of cattle, goat, sheep, and pig
(Springer, 2008-09)Increasing productivity is one of the main objectives in animal production. Traditional breeding methods have led to increased gains in some traits but gains are not easily attainable in traits with low heritabilities. ... -
