ABSTRACT Background: Surgical site infections (SSIs) are the most common healthcare-associated infections affecting surgical patients. Such infections are often caused by methicillin-susceptible as well as methicillin-resistant Staphylococcus aureus. Methicillin-resistant Staphylococcus aureus (MRSA) is resistant to the entire class of beta-lactam antimicrobials; which are largely used in clinical medicine. Patients infected with MRSAs therefore have limited therapeutic options, and this ...
ABSTRACT The main source of animal protein is livestock and their products. Livestock plays a crucial role in the economy of most nations. Parasitism is one of the main constraints limiting livestock productions. Control of parasitic diseases communicable from animals to men under natural conditions is very necessary to improve the health status of Ghanaians. The research was aimed at determining different parasites and compares the prevalence of infections at certified and uncertified abatt...
ABSTRACT There have been several reports on the antimicrobial activity of different herbal extracts. Medicinal plants are believed to be the best source for obtaining a variety of drugs. Hibiscus sabdariffa L. is a medicinal plant known for its nutritional delicacy and medicinal properties such as the treatment of diseases like hypertension, coughs, biliousness, boils and wounds. Currently, the main therapy for bacterial infections is the use of synthetic antibiotics. However, the misuse and...
ABSTRACT Samples of oils and fats of different degree of unsaturation namely; shea butter, palm oil and groundnut oil were heated at three different temperatures (150°C, 110°c and 190°C) for 2, 4, 6, 8 and 1 Ohrs using a temperature regulated, lidded-deep frying equipment. The changes in some chemical properties were monitored. These chemical properties include acid value, iodine value, saponification value, peroxide value and volatile content. The total phosphorus contents were also monit...
ABSTRACT This project is concerned with the development and evaluation of an atom-trapping technique for determination of heavy metals in environmental samples. Modified atom-trapping technique using fabricated nickel tube/sample holder (crucible) was employed to increase the sensitivity of a flame atomic absorption spectrometry. Basic performance data for different parameters, such as burner height and the height of the support, were studied. Different designs and ways of placing the atom tr...

ABSTRACT Most experimental situations call for standard designs that can be constructed with many statistical software packages. In some situations, however, standard designs are not appropriate or practicable. Computer-aided designs are experimental designs that are generated based on a particular optimality criterion and are generally optimal only for a specified model. In this work designs are generated for non-standard multifactor experiment using D-optimality criterion. The experiment in...
ABSTRACT Several non-linear models have been proposed by various authors for the analysis of growth data. I n this thesis, three models, viz, Gompertz, Exponential and Polynomial models were used to analyze some forestry data, namely, a tree specie known as Tectona Grandis, collected in the Guinea savanna zone of Nigeria. The three models were compared and using the criteria of low mean square error and high coefficient of determination, it was found that the Gompertz model fits the data best...
ABSTRACT Complexes of 4 - Cyanobenzaldehydecylohexyl acetic acid hydrazone ( 4-CBAH) with M(II) sulphates and acetates have been synthesized (M=Ni, Cu, Co and Zn). The complexes were characterized by elemental analyses, conductance, infrared and electronic spectral studies . . The sulphate ions are in the outer coordination sphere, so also the acetate 10ns. The electronic spectral studies of the isolated complexes indicate an octahedral coordination for Ni2+ and Co2+ complexes while Cu2 + com...
ABSTRACT Nine pesticide residues were detected in soil and water samples from the Waanpu Dam in the Bimbilla District of Ghana at varying mean concentrations using Gas Chromatography. The pesticide residues detected in the soil and water samples were chlorpyrifos, beta-endosulfan, cypermethrin, aldrin, heptachlor, beta-BHC, heptachlor-epoxide, dieldrin, and methoxychlor. The concentration of beta-endosulfan was the highest among all the pesticides detected. It ranged from 0.001 – 0.070 µg...
ABSTRACT Quaternary ammonium compound was synthesized from epoxy and fatty amine reaction. Fourier Transform Infrared(FTIR) spectrometric analysis of the starting materials, and the final product(N-benzyl-N,N-dioctyl-2-hydroxy-3 phenoxypropylammonium chloride) were conducted, and results showed a disappearance of sharp N-H peak of 2o amine, and appearance of broad O-H peak of alcohol in the spectrum of the final product. Mass spectrometric(MS)analysis of the final product was also conducted, ...
ABSTRACT This dissertation presents a systematic and critical study of the fundamenta.lli of soft set theory which includes soft set operations, soft set relations and functions, soft matrices and their properties. In course of studying operations on soft sets, the complementation operation is strengthened, some new results on distributive and absorption properties with respect to various soft set operations are obtained,and soft set operations and their corresponding soft matrix operations a...
ABSTRACT Yersinia enterocolitica and Yersinia pseudotuberculosis are important food and water borne pathogens that has recently emerged world wide. This study was aimed at characterizing the prevalence of Yersinia enterocolitica and Yersinia pseudotuberculosis in human and selected animal populations in Jos and its environment. Three thousand stool samples from human and selected animal species from 5 different locations in Jos and its environs were surveyed over a period of three years. Huma...
ABSTRACT Valerohydroxamic and Isovalerohydroxamic acids were synthesised and recrystallised from ethylacetate. They were characterised by melting point, pka and spectral (IR NMR) studies. Their melting points are 77.78°C and 76.77°C for valerohydroxamic acid and isovalerohydroxamic acid respectively and their pka values at 0.1mol dm-3 at 28°C are 9.50+0.01 and 9.51+0.01 for valerohydroxamic acid and isovalerohydroxamic acid respectively. The IR and NMR (1H and 13C) for both valerohydroxami...
ABSTRACT Studies were carried out on the distribution, characterization, pathogenicity and antibiotic susceptibility of Listeria monocytogenes in Six Local Government Areas of Plateau State, Nigeria. A total of One hundred and fifty (150) experimental samples were taken from each test Local Government Area.
