ABSTRACT Let H be a real Hilbert space and K a nonempty, closed and convex subset of H. Let T : K ! K be an asymptotically nonexpansive map with a nonempty xed points set. Let fng1n =1 and ftng1 n=1 be real sequences in (0,1). Let fxng be a sequence generated from an arbitrary x0 2 K by yn = PK[(1 tn)xn]; n 0 xn+1 = (1 n)yn + nTnyn; n 0: where PK : H ! K is the metric projection. Under some appropriate mild conditions on fng1n =1 and ftng1 n=1, we prove that fxng converges strongly ...
ABSTRACT Diabetes mellitus is a metabolic disorder of multiple etiology, characterized by chronic hyperglycemia with disturbances of carbohydrate, fat and protein metabolism resulting from defects in insulin secretion, insulin action or both. It is associated with significant morbidity and mortality due to cardiovascular complications as a result of imbalance in lipid metabolism. Diabetic foot ulcers (DFUs) are estimated to occur in 15% of all patients with diabetes and precede 84% of all dia...
ABSTRACT Pelargonium sidoides is a medicinal plant grown in Kenya for export to Germany where it is used in the manufacture of drugs for lung related diseases. The farm contributes to the well being of the local community by providing permanent employment to for over 80 persons, with 80 percent being women. It also offers free pre-primary education to their children including the ones from the neighbourhood. The broad spectrum of activity against viruses and bacteria may be caused by the coum...
ABSTRACT Cadmium (Cd) is a ubiquitous environmental and industrial pollutantwhose exact toxicity mechanisms still remain elusive. However, cumulative data has implicated bioaccumulation as well as free radical generation in the biochemical and molecular mechanisms of cadmium induced toxicity. Chelation therapy with calcium disodium ethylenediamine tetra acetic acid (CaNa2EDTA), British Anti Lewisite (BAL), meso 2, 3-dimercaptosuccinic acid (DMSA) is so far among the best known treatment again...
ABSTRACT Mozzarella cheese is prepared using milk from various herbivores. Mostly, it is prepared using milk from sheep, cow and goat. However, due to consumers‘ demand for healthier foods, cheese processors have been innovatively preparing unique cheeses. Mozzarella cheese is one of the preferred ingredients for use on pizza. Goat milk is a good source of protein and calcium, possessing unique characteristics with a high proportion of small milk fat globules that contain a higher concentr...
ABSTRACT The effect of combinations of superphosphate and Minjingu phosphate rock (a sparingly water-soluble fertiliser) in the percentage ratios of superphosphate to Minjingu phosphate rock of 10:90, 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, 80:20 and 90:10 was studied in a laboratory incubation experiment. Three acid soils from Rift Valley Province having contrasting chemical properties were used. The treatments consisted of three P sources (superphosphate, Minjingu phosphate rock and m...
ABSTRACT Crucifers form an important component of the livelihood of small-scale farmers in East Africa but diamondback moth (DBM) pest constrains their production. Attempts to control the pest by use of host plant resistance (HPR) have been modest especially in cultivars expressing a whitish appearance (normal wax bloom). Conversely, crucifers characterized by their shiny dark green leaves (Glossy) have shown some resistance to DBM. As a consequence, several seed companies claim resistance a...
ABSTRACT Theconcentrations of lead, nickel, silver, zinc, chromium, copper, vanadium, cobalt, and cadmium were determined in plastic housing of waste television sets produced in some years of 1980’s, 1990’s and 2000’s, and in plastics of waste mobile phones produced in some years of 1990’s and 2000’s, the samples were collected mainly from mobile phone and television repairers at railway in Ogbete main market, Enugu in Enugu state, and the famous computer village inIkeja, Lagos Sta...
ABSTRACT Geomagnetic storms are temporal disturbances of the Earth’s magnetosphere caused by a prolonged southward interplanetary magnetic field and usually coinciding with the arrival of coronal mass ejections (CME). Most geomagnetic storms occur under disturbed condition making it intrinsically uneasy to distinguish one geomagnetic storm from another especially in respect of the solar origin. Thirty four (34) geomagnetic storms occurring between 1997-2012 have been studied whose storm si...
ABSTRACT In this theses, we investigate certain key aspects of mathematical modelling to explain the epidemiology of HIV/AIDS, Tuberculosis, Hepatitis B, Tumour,diabetes and stroke at the workplace and assess the potential benefits of proposed control strategies. The compartmental epidemiological modelling approach was used in the formulation of the models on HIV/AIDS, tuberculosis (TB), Hepatitis B (HBv), Tumour and Diabetes pandemic. In each of the cases, the dynamics of the disease was st...
ABSTRACT Reservoir characterization has taken prominence in hydrocarbon exploration due to its role in proper understanding of the reservoir properties such as lithofacies, and petrophysical parameters, to enhance success in the quantification of the hydrocarbon reserve in place thereby diminishing exploration failures and enhancing successes. This research work is aimed at integrating three-dimensional seismic data and petrophysical log data to characterize reservoirs of interest, map struc...
ABSTRACT Modeling of time series with many observations has been a focus of considerable research both in theoretical and empirical applications over the last three decades. However, the problem of short time series modeling has not so far been adequately studied both in theory and practical applications, despite the fact that many real life situations involve fewer observations leading to short time series. This calls for making use of appropriate estimation techniques in order to come up wi...

ABSTRACT Although molecular toxins and emission of particulates from the thermal degradation of biomass materials such as meat is a complex area of study, it has become necessary to investigate this phenomenon and determine how it affects biological functions and as precursors for cancer, degenerative diseases that stress the respiratory landscape. Accordingly, this study describes the pyrolysis of goat meat in the temperature range 300-525 ˚C. Goat meat sample of 10±0.2 g was heated under...
