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 ...
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. ...
A general introduction about the need for studying forest dwelling primate populations in fragmented landscapes and more specifically in the Soutpansberg is given in Chapter 1. Forests affected by fragmentation are at ...
The main malaria agent, Plasmodium falciparum, exhibits a complex life cycle. The parasite initially develops in a poikilothermic mosquito vector before it is subsequently transmitted to a homeothermic human host. As such, ...
Wild plants have been used since time immemorial by native people all over the world. In many sections of the rural areas, people traditionally harvest wide range of leafy vegetables, roots tubers and fruits from the wild ...
Perovskite-based solar cells (PSC) is the fastest growing solar technology to date since inception in 2009. This technology has invigorated the photovoltaic (PV) community. While it has taken 15-42 years for traditional ...
Stream flow and water temperature regimes are master variables driving river ecosystems, which determine the spatial and temporal dynamics of plant, benthic and other taxonomic groups in streams. Stream flow and water ...
Background: Acute gastroenteritis (AGE) is a major cause of morbidity and mortality in children globally. Several reports have indicated that diarrheal diseases caused by viruses, bacteria and parasites are associated with ...
Short-term load forecasting in South Africa using machine learning and statistical models is discussed in this study. The research is focused on carrying out a comparative analysis in forecasting hourly electricity demand. ...
Wind offers an environmentally sustainable energy resource that has seen increasing global adoption in recent years. However, its intermittent, unstable and stochastic nature hampers its representation among other renewable ...
