Analyses of LULC dynamics in a socio-ecological system of the Bale Mountains Eco Region of Southeast Ethiopia.
(Springer Science and Business Media Deutschland GmbH, 2024-06-21)
Analysis of land use and land cover (LULC) change and its drivers and impacts in the biodiversity hotspot of Bale Mountain’s socio-ecological system is crucial for formulating plausible policies and strategies that can ...
Wind dispersed tree species have greater maximum height.
(John Wiley and Sons Inc, 2024-06-14)
Aim: We test the hypothesis that wind dispersal is more common among emergent tree species given that being tall increases the likelihood of effective seed dispersal. Location: Americas, Africa and the Asia-Pacific. Time ...
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 ...
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 ...
The effects of vaccination and treatment on the spread of HIV/AIDS
(World Scientific Publishing, 2004)
This study investigates the effects of vaccination and treatment on the spread of HIV/AIDS. The objectives are (i) to derive conditions for the success of vaccination and treatment programs and (ii) to derive threshold ...
Significance of antiviral therapy and CTL-mediated immune response in containing hepatitis B and C virus infection.
(Elsevier B. V., 2021-01-12)
Viral infections remain a major cause of deaths globally. Here, we focus on Hepatitis B and C viruses (HBV and HCV) infection dynamics in the liver and blood cells, taking into account non-cytotoxic and cytotoxic mediated ...
Evaluation of three breeding cycles for seedling weight of switchgrass, big bluestem, and indiangrass.
(Crop Science Society of America, 2014-07-01)
A modified form of restricted, recurrent phenotypic selection was used to select for seedling shoot weight in switchgrass (Panicum virgatum L.), big bluestem (Andropogon gerardii Vitman), and indiangrass [Sorghastrum nutans ...
Modeling salmonellosis transmission dynamics in humans and dairy cattle with optimal controls.
(Elsevier Inc., 2025-02)
In this paper, we develop a mathematical model to examine the transmission dynamics and control analysis of salmonellosis in humans and dairy cattle. The model considers three time-dependent controls (improving hygiene, ...
Assessment of heavy metal enrichment and degree of contamination around the copper-nickel mine in the Selebi Phikwe Region, Eastern Botswana
(Horizon Research Publishing Cooperation, 2013)
This paper focuses on heavy metal (Co, Cu, Fe, Pb, Mn, Ni and Zn) enrichment and degree of contamination in the soils windward of the Selebi Phikwe copper and nickel mine (eastern Botswana). Pollution by these metals was ...
