Abstract This work takes a look at different computational algorithms used in solving initial value problems and how these algorithms arc derived from Taylor's series. It also made use of the Euler and Runge-Kutta method to solve initial value problems in order to compare the performance of the two methods.
ABSTRACT This study involved the isolation, purification and characterisation of the bioactive phytochemicals from the ethanolic extract of young twigs and leaves of C. bonduc, the determination of the antimalarial activity of each isolated phytochemical, and the investigation of their in vivo toxicological effects. Further extractions were carried out using petroleum ether, ethyl acetate, butanol and water. Bioassay-guided fractionations of petroleum ether and ethyl acetate fractions were c...
Abstract This project report deals with the class of asymptotically demicontractive mappings in Hilbert spaces. We noted some historical aspects concerning the concept of asymptotically demicontractivity and studied a regularized variant of the Krasnoselskii-Mann iteration scheme, which ensured the strong convergence of the generated sequence towards the least norm element of the set of _xed points of asymptotically demicontractive mapping.
ABSTRACT Detailed field based structural, fracture and paleostress analysis were carried out on Cenomanian to Maastrichtian units forming the Afikpo syncline structure. Three fracture systems were isolated from analysis of fracture orientations and thier field relationships: Pre-folding (JT), Syn-Folding (JS) and Post Folding (JC) fracture systems. Paleostress analysis carried out on these fracture systems using the TENSOR™ software tool (Delvaux & Sperner, 2003) yielded three paleostress ...
ABSTRACT The immunomodulatory properties of methanol extract and fractions of Hoslundia opposita leaf on Delayed-Type Hypersensitivity (DTH), primary and secondary humoral response and in vivo leucocyte mobilization were evaluated. Acute toxicity test of crude extract and phytochemistry study was carried out. The methanol extract (ME) at 200, 400 and 800 mg/kg body weight produced significant (P
ABSTRACT A geophysical investigation involving the electrical resistivity method was carried out at IkoleEkiti of South Western, Nigeria with the main aim of investigating the area for groundwater potential of the regolith aquifer. The objectives are to identify geological structures and aquifers favorable to groundwater accumulation andalso input geoelectric layers parameters into a software to produce maps of the subsurface in order to determine the groundwater potential of the regolit...
ABSTRACT This research study is designed to determine the microbial count of Chicken Droppings and Ground Palm kernel shell in which the chicken droppings is used as inoculum on Ground Palm Kernel Shell at Ratio 2: l in which the inoculum size is half of the Ground Palm Kernel Shell. Pollution of the environment due to oil production can be reduced through this study because is aimed at examining the microorganism responsible for the biodegradation that can be achieved in Palm kernel she...
ABSTRACT This study is aimed at evaluating the proP,hylactic activity of Phy/lanthus amarus and Diodia scandens in synergism on the Swiss albino rats. The two plants were obtained from Federal University Oye-Ekiti and its environs, thoroughly washed with distilled water and air dried at room temperature for two weeks. The air dried plant materials were pulverized into powdery form using house-hold electric blender. Ethyl-acetate extracts of the two plants combined was administered orally in ...
ABSTRACT This study aimed at developing agar extraction protocol from local Gracilaria salicornia species and investigates its physico-chemical characteristics, production cost and application in tissue culture of Pleurotus HK-37. Purposive sampling was used in collection of Gracilaria salicornia during dry (northeast monsoon) period in 2016 at Chwaka bay, Zanzibar, Tanzania. A 33 factorial experimental design was used in the extraction of treated agar whereby three independent variables of ...
Abstract Although magmatism may occur during the earliest stages of continental rifting, its role in strain accommodation remains weakly constrained by largely 2-D studies. We analyze seismicity data from a 13 month, 39-station broadband seismic array to determine the role of magma intrusion on state-of-stress and strain localization, and their along-strike variations. Precise earthquake locations using cluster analyses and a new 3-D velocity model reveal lower crustal earthquakes beneath th...
ABSTRACT This study was carried out to determine the prevalence of malaria parasite among patients with sickle cell trait in Ekiti state. A total of 20 samples were collected from different hospitals and clinics. The samples were collected randomly and sodium metabilsulphite was employed to confirm the sickling trait in the samples and thereafter the malaria parasite kit was used to test for the prevalence of malaria in the samples. Eight (8) persons who tested positive for sickle cell trait...
ABSTRACT This research work presents the optimization of the reaction parameters for the productions of HMF from Tanzanian sugarcane bagasse under pressurized conditions using high pressure reactor. The sugarcane bagasse (25 g) was hydrolyzed at different temperatures, different concentrations of the hydrolyzing acid, and different reaction time. A total of 27 hydrolysis experiments were carried out in a non-stirred SS-304 pressure reactor. The sugarcane bagasse was hydrolyzed using sulphuri...
ABSTRACT The seeds and peels of African star apple (Chrysophyllum albidum) (“udara”) were split, followed by removal of mucilage from the seeds and subsequent cracking of the seed shells, and de-pulping of the peels. The seed cotyledons and peels were blanched at 1000C for 2,4 and 6 mins, wet milled with water in 1: 1.5 ratio, sieved with muslin cloth to obtain the extracts which were pasteurized at 800C for 10mins and stabilized with 0.2, 0.4, 0.6, 0.8 and 1.0 (g/litre) concentrations o...
ABSTRACT An integrated investigation involving electrical resistivity method, Induced polarization method, and triaxial tests were used to investigate an abandoned senate auditorium in university of Nigeria, Nsukka, southeastern Nigeria. This was with a view to determining or imaging the subsurface structure as they may cause instability and led to multiple cracks of the building. The building in the study area is intensively affected by severe cracks. The electrical resistivity and induced ...
