Technological tools for sustainable development in developing countries: The example of Africa, a review
(Elsevier, 2017-10)Abstract The development of Africa including industrialization such as chemical production, urbanization, agriculture, waste disposal, and electric power generation has a direct and diverse effect on the environment. These ... -
Trace Metal Detection in Aqueous Reservoirs Using Stilbene Intercalated Layered Rare-Earth Hydroxide Tablets
(Hindawi, 2020-03-30)Contamination of aquatic reservoirs with metal ions is a slow gradual process that is not easy to detect. Consequences of the metal ions, especially the ones with high atomic numbers (heavy metals) at high concentrations, ... -
Transpirational water use and its regulation in the mountainous terrain of S. Korea
(American Geophysical Union, 2009)Quantifying water use by forests growing on complex mountainous terrain is difficult and understanding of controls on water use by these forests a challenge. Yet mountains are crucial as water towers and better understanding ... -
Treatment of tea industry wastewater using a combined adsorption and advanced oxidation process
(International Conference on Sustainable Research and Innovation, 2014)Tea, produced from the evergreen plant, Camellia Sinensis, is the most widely consumed beverage in the world after water. Although tea processing has now diversified into various speciality end products such as instant, ... -
Tree growth and water-use in hyper-arid Acacia occurs during the hottest and driest season
(Springer-Verlag GmbH Germany, 2018)Drought-induced tree mortality has been recently increasing and is expected to increase further under warming climate. Conversely, tree species that survive under arid conditions might provide vital information on successful ... -
Two dimensional mathematical models for convective-dispersive flow of pesticides in porous media
(International Journal of Engineering Science and Computing, 2016)The transport of solutes through porous media where chemicals undergo adsorption or change process on the surface of the porous materials has been a subject of research over the years. Use of pesticides has resulted in ... -
Understanding the Long-Lasting Attraction of Malaria Mosquitoes to Odor Baits
(Plos One, 2015-02-23)The use of odor baits for surveillance and control of malaria mosquitoes requires robust dispensing tools. In this study, the residual activity of a synthetic mosquito attractant blend dispensed from nylon or low density ... -
Use of Infinitesimal Transformations in obtaining the Generator of a harmonic fourth order non-linear ordinary differential equation.
(International Journal of Engineering& Scientific Research, 2017-05-05)Lie group Theory is applied to differential equations occurring as mathematical models [4]. This paper seeks to obtain a generator T for a harmonic fourth order non-linear ordinary differential equation using the Lie ... -
The Use of Machine Learning, Density Functional Theory, and Molecular Dynamics Simulations for the Designing and Screening of Efficient Small Molecule Donors for Organic Solar Cells
(International Journal of Quantum Chemistry, 2022-12-05)Indeed, a proper understanding of materials is necessary to get the full benefit from them. For this purpose, multiscale computational modeling is the ultimate need. For machine learning analysis, data is collected from ... -
Use of Semiochemicals for Surveillance and Control of Hematophagous Insects
(Chemoecology, 2020-06-23)Reliance on broad-spectrum insecticides and chemotherapeutic agents to control hematophagous insect vectors, and their related diseases is threatened by increasing insecticide and drug resistance, respectively. Thus, ... -
Using organic wastes as feed substrates for black soldier fly larvae
(Wegeningen Academic Publishers, 2021-08-25)Feeding black soldier fly larvae (BSFL) on locally available organic wastes has the potential of providing an alternative source of protein to fishmeal and soybean used in animal feed formulation. This can also mitigate ... -
Using Self-Regulated Learning to Enhance Mathematics Achievement among Grade 11 Learners in Kenya
(Inderscience Enterprises Ltd., 2022-12-01)The study investigated the effect of self-regulated learning (SRL) on mathematics performance among learners in Kenya. The study employed Solomon four research design. A sample size of 408 grade 11 learners from four schools ... -
Variation in Temperature and Nutrient Source Influence the Growth of Exserohilum Turcicum Mycelia Isolated from Sorghum
(Journal of Scientific and Engineering Research, 2019)Turcicum leaf blight (TLB) caused by the fungus Exserohilum turcicum is a serious threat toproduction of maize and sorghum, since it damages photosynthetic leaves. Growth and development of E.turcicum pathogen is influenced ... -
Volatility Estimation Using European-Logistic Brownian Motion with Jump Diffusion Process
(International Journal of Mathematics And its Applications, 2020)Volatility is the measure of how we are uncertain about the future of stock or asset prices. Black-Scholes model formed the foundation of stock or asset pricing. However, some of its assumptions like constant volatility ... -
Vulnerability of Nyabarongo River Water Abstraction to Climate Change in Rwanda
(International Journal of Environmental Sciences, 2023-02-13)Purpose: Climate change in Rwanda is a great challenge resulting from increased temperature and causing abnormal variability in weather variables and threatening the socio-economic welfare of human beings. Water resources ... -
Water use by a warm-temperate deciduous forest under the influence of the Asian monsoon: contributions of the overstory and understory to forest water use
(Elsevier, 2013)The warm temperate deciduous forests in Asia have a relatively dense understory, hence, it is imperative that we understand the dynamics of transpiration in both the overstory (E O) and understory (E U) of forest stands ... -
Wilson-Theta Algorithm Approach to solution of Dynamic Vibration Equations
(ResearchGate, 2014)In this paper, we examine conservative autonomous dynamic vibration equation, x¨ = − tanh2 x, which is time vibration of the displacement of a structure due to the internal forces, with no damping or external forcing. ...
