This paper designed a Mathematical Model which provides a good description of blood flow regimes via constricted and unconstricted vessels that induces high blood pressure. It also presents a solution which will predict the rates of blood flow and the pressure profiles across the domain.
Utilization of sawmill wood wastes as household energy source in Benin City was investigated. A multistage random sampling technique was used to select 10 wards within the study area. Thirty households were then selected in each ward thus making a total of 300 respondents. The result showed that 67.2 and 14.5% of the respondents use sawmill wood wastes for cooking and for processing of farm produce respectively.
ATM services provided by banks and non financial institution have appeared as the most E - Banking instruments that had become so popular in Nigeria. The belief that ATM is dependably provided by a bank, the transactions and the data being transmitted must be secured. This belief might hold in the past, but at the moment ATMs are now able to use operating systems, such as Microsoft windows and Linux. These operating systems do expose ATM to vulnerability akin to the same kind of problems displayed by conventional computers.
Three african oil seeds of soyabean (Glycine max L. Merill) Beniseed (Sesamu indicum L. ) and melon (Cucumis melo L. ) were evaluated as potential oil seeds in a southern guinea savannah agro-eosystems, using soyabean as a standard reference crop. Experimental techniques included approved Association of Official Analytical Chemist (AOAC1984) for proximate analysis, kjedahl for protein estimate and soxlet extraction using petroleum spirit as a solvent for l content.
Potentiometric Studies on the dissociation constants of amino acids were carried out. The dissociation constants of amino acids were determined using ‘ORIGIN 50’ Program, as an attempt to find an alternative way for determination of the dissociation constants of amino acids, pKa, instead of the conventional calculation methods.
Population dynamics studies reveal the fluctuations in an organism’s population over time, in relation to prevailing climatic conditions; thus providing a fundamental background for evaluating and determining appropriate control strategies for adoption. This study in Bayelsa State, Southern Nigeria has revealed that C. sordidus population experiences a gradual build-up with onset of rains (early March), and attain peaks between May and early November.
Paspalum scrobiculatum and Azonopus compressus were used to study the accumulation and deposition of lead in tissues of roots, rhizomes and leaves, as well as their impact on changes in the anatomy of their tissues. Four (4) kg of air dried soil was measured into Four (4) kg perforated plastic buckets. Waste engine oil was added to Four (4) kg different soil samples to obtain different concentrations on weight basis: 0% (control), 2%, 4%, 7% and 10% v/w oil-in-soil and allowed to stand for seven days before transplanting. The plants were harvested after 8 weeks of transplanting.
Malaria infestation in Nigeria is still worrisome, hence, the need for new antimalarial agents. This study, therefore, investigates the antiplasmodial activity of the ethanolic extract and flavonoid fraction of the stem of P. amarus in the blood, brain, liver and pancreas of Plasmodium berghei (chloroquine sensitive NK65 strain) infested mice.
Knowledge of the chromosome morphology of a species is valuable in detecting chromosomal abnormalities, taxonomy and evolution. Despite this, chromosomal studies on rabbits is scarce in Nigeria. This study presents a description of the chromosome morphology of Oryctolagus cuniculus from Ilorin, Nigeria. Two male and one female samples received intraperitoneally 0.01% colchicine (1ml/100g body weight). The chromosomes were investigated by examining the metaphase chromosome spreads obtained from the bone marrow of the femur and humerus.
The ability of Digitaria horizontalis and Eluesine indica grass species to phytoremediate waste engine oil contaminated soil was investigated. Four (4) kg of air dried soil was measured into four (4) kg perforated plastic buckets. Waste engine oil was added to four (4) kg different soil samples to obtain different concentrations on weight basis: 0 % (control), 2 %, 4 %, 7 % and 10 % v/w oil-in-soil and allowed to stand for seven days before transplanting. At the end of 8 weeks of transplanting, the plants were harvested.
