Groundwater is the main source of drinking water for majority of rural communities worldwide. This essential resource is often contaminated leading to various medical complications in man. Some groundwater have been found ...
The World urban population is increasing rapidly, in a context in which small, intermediate towns and cities have been found to be inadequately prepared to manage such pressures. One area in which cities have been ...
Seasonal variation and long-term change in climate have a direct impact on the form, scale, spatial and temporal effects on maize farming. Adaptation is key to reducing the effects. Several costs accompany the adaptation ...
This study aims to synthesize silica gel-based adsorbents for organic contaminated wastewater treatment using diatomaceous earth as the silica precursor. First, the extraction of silica from diatomaceous earth was optimized ...
Quinolines are well known naturally occurring heterocyclic compounds with nitrogen as a heteroatom. Quinolines are also one of the major classes of naturally occurring compounds and the interest in their chemistry is due ...
BACKGROUND: Child daycare centers (DCCs) host a variety of pathogenic enteric microorganisms which may be found in various areas within the compound. Enteric pathogens are the most common cause of diarrhoea worldwide in ...
The sun is the most important source of renewable energy today. Producing energy from sunlight using cheap, abundant and non-toxic materials is considered a major challenge in the field of solar-electrical energy conversion. ...
Solar irradiance forecasting is essential in renewable energy grids amongst others for back-up programming, operational planning, and short-term power purchases. This research study focuses on forecasting hourly solar ...
The age distribution of a population is one of the most important demographic factors that plays a major role in describing and making projections about the population. Age distribution determine life expectancy, fertility ...
Coupled with irreversible shifts, climate-driven disturbance of ecosystems will probably be the largest impact of climate change on humans. With higher rainfall variability and more intense events, separated by extended ...
Pollination of flowering plants is mostly facilitated by insects. However, there is a global decline in the pollination services caused by invasive alien plants (IAPs), excessive use of pesticides, habitat loss, and ...
The study focuses on the application of hierarchical time series in forecasting electricity demand using South African data. The methods used are top-down, bottom-up and optimal combination. The top-down method is based ...
Glioblastoma multiforme (GBM) is the deadliest brain tumour. GBM is associated with poor prognosis, with its patients having a very short median survival and poor response to chemotherapy. GBM is a World Health Organization ...
Malaria is caused by protozoan parasites of the Plasmodium genus. An estimated 405 000 million deaths due to malaria were reported in 2018. Plasmodium falciparum (P. falciparum) accounts for the deadliest form of the disease ...
Adsorption of Coomassie brilliant blue (CBB G-250) from aqueous solutions on the adsorbents chitosan, alpha cellulose, banana rachis fibre, banana rachis fibre/chitosan composite, alpha cellulose/chitosan composite, and ...
Developing countries are largely characterized by rural-based communities often settled in headwater catchments whose livelihoods are dependent on natural resources available. As the climate changes, hydrological regimes ...
Microplastics have become a major environmental concern globally due to their potential impacts on ecosystem function. They are known to be ubiquitously present, persistent and bio−accumulative, yet ecological impacts of ...
Leaf litter contributes to the functioning of aquatic ecosystems through allochthonous inputs of carbon, nitrogen and other elements. In many freshwater ecosystems, leaf litter inputs are among the most important cross-ecosystem ...
Water availability plays an important role in the habitat requirements of bats. Previous studies have shown that water bodies (both natural and artificial) are used by bats and other animals for drinking water and foraging. ...
Understanding the spatial variability of selected soil fertility indicators could make it possible to optimize the use of agricultural inputs with the reduction of economic and environmental risks. The aim of this study ...
