There is a crucial need in Nigeria to enhance the development of wind technology in order to boost our energy supply. Adequate knowledge about the wind speed distribution becomes very essential in the establishment of Wind Energy Conversion Systems (WECS). Weibull Probability Density Function (PDF) with two parameters is widely accepted and is commonly used for modelling, characterizing and predicting wind resource and wind power, as well as assessing optimum performance of WECS. Therefore, i...
Sorption and desorption of rifampicin was assessed on three different soil. Sorption mechanism was studied in terms of equilibrium and kinetics at different pH. Linear, Freundlich and Langmuir isotherm models were adopted to study the isotherm. The experimental data were best described by pseudo-second order kinetics (R2 = 1.00). It was observed that rifampicin absorbs better on soil with lowest organic carbon content. Sorption was observed to increase with decrease in aqueous pH and increase...
The continent of Africa has recorded impressive economic growth for over two decades. Factors identified as contributing to this growth include commercial oil deposits, inflation control, government liberalization and privatization policies, foreign direct investment, private sector investment in industries such as construction and service sectors, and a strong agricultural production. The continent is likely to continue enjoying strong economic growth if these resources are well managed. Afr...
ABSTRACT The neuromuscular junction (NMJ) is a unique, specialized chemical synapse that plays a crucial role in transmitting and amplifying information from spinal motor neurons to skeletal muscles. NMJ complexity ensures closely intertwined interactions between numerous synaptic vesicles, signaling molecules, ion channels, motor neurons, glia, and muscle fibers, making it difficult to dissect the underlying mechanisms and factors affecting neuro-degeneration and muscle loss. Muscle fiber...
ABSTRACT The increasing demand for road transport in Nigeria and the huge Government investment on roads have generated the need to encourage road maintenance and sustainability. This project work covers the importance of managing information and the importance of keeping past records for the Federal Road Maintenance Agency (FERMA) and how to improve on it. And it also cover the following areas: work monitoring process file, staff information file, road and bridge maintenance file, amount spe...
ABSTRACT Ivermectin (IVM), a dihydro derivative of avermectin (AVM), originating solely from the fermentation products of Streptomyces avermitilis had an immeasurably beneficial impact in improving the lives and welfare of billions of people worldwide. Originally introduced as a veterinary drug, it was quickly discovered to be ideal in combating two of the world’s most devastating and disfiguring diseases; onchocerciasis and lymphatic filariasis (LF) which has plagued the world’s poor ...
ABSTRACT Tungiasis is an ecto-parasitic disease of humans and animals caused by the burrowing of gravid female fleas of the genus ‘Tunga’. Of the known species of Tunga fleas, Tunga penetrans and Tunga trimamillata are parasites of humans besides other warm blooded mammals, most of which are peri-domestic. The host of the others is limited to a few genera of wild mammals. The burrowed female flea rapidly expands its body size, causing immense itching, inflammation, pain and debilitation. ...
Pension, being regular payments made to retirees or their beneficiaries after retiring from active service, needs efficient and effective management because of the funds involved as the living standard of the retirees and their dependants rest on it after retirement. In attempt to maximize the wealth of pension contributors, the investors may end up losing the pension fund assets because higher returns on investment go hand in hand with higher risk of loss of invested contributions/savings. T...
Abstract: This research has helped us to ascend from the initial two exploratory studies to a more advanced general conclusion and theory that tea leaves (Camellia sinensis) has a great potential for Pb(ii) and Zn uptake, as such, a more suitable Low-cost adsorbent for the effective removal of Pb (II) and Zn from industrial effluents waste water than tea fibre. This is coined from the results of the different biosorption studies carried out as a function of contact time, initial metal...
Parkinson’s disease is a degenerative neurological disease, which is characterized by the preferential death of dopaminergic neurons in the Substantia Nigra. Current drug treatments are aimed primarily for the treatment of symptoms to improve the quality of life. Therefore, there is a need to find out new therapeutic strategies that not only provide relief but also halt or reverse the neuronal damage hampering PD progression, thus this research therefore aimed at investigating the impact o...
The calabash (Cresentia cujete) fruit was studied for its proximate and mineral composition as well as its phytochemical constituents. The sugar content, energy content, protein, nitrogen, crude fibre, moisture content, sucrose, fructose, galactose and energy content are quite reasonably high (viz: 1.13%, 8.35%, 1.34%, 4.28%, 84.92%, 59.86%, 25.09%, 18.24% and 88.69%). The pH of the fruit falls within the acidic range (4.8) and the mean value recorded for the electrical conductivity...
Delonix regia popularly known as the flamboyant plant because of its onyx attractive color has been generally cultivated in the tropics. Although it was widely cultivated in the 19th century, yet the native habitat of the flamboyant tree was unknown until the 1930s, when it was retraced to native growing in the wild in Madagascar. The uses of Delonix regia as binders in drugs, adhesives, stabilizers, etc. have been some of its numerous applications in the field of science and biomedicine and ...
ABSTRACT Laboratory experiments were conducted to evaluate the effects of deltamethrin dust as a protectant of maize against Sitophilus zeamais under ambient laboratory conditions of 27 ± 3°C and 70 ± 5% relative humidity. Four sets of fifty grams of disinfested maize grains were measured into jars in four replicates. Each replicate was infested with ten 0-7days old adult S.zeamais. Each set of three replicates were treated separately with 0.25g, 0.187g and 0.125g of deltamethrin while th...
The mathematical equations and concepts we learned in schools can actually be summed up to be relevant in the prediction, estimation and understanding of certain real world situations or problems that surrounds us. Some examples could be, How can we predict the break of a new infectious disease affecting the country Nigeria? How can reduction in the import of items into the country Nigeria affect the long term economy of the country Nigeria? How can we apply certain mathematical concept in ...
ABSTRACT The place of adequate nutrition in the live of the young especially in the recently weaned cannot be overemphasized. The abrupt change in diet, leading to possible immune system weakness and disease conditions, is a focal point in the care of the young. This project examined serum globulin and bilirubin levels in weanling rats whose feed was supplemented with Emilia sonchifolia leaf extract.Present investigation were carried out on the effect of ethanolic extract of Emilia Sonchifo...
