ABSTRACT Euphorbia L. is a genus of the family Euphorbiaceae. Some of the species are culturally, economically and medicinally valuable. The taxonomy of the genus was re-evaluated using classical and experimental approaches to unravel the complex inter-relationships and problems of identification existing within the genus. Herbarium studies, natural population sampling, ecological observation, experimental cultivation, morphological and anatomical characterization were some of the study appr...
Background of study Polycyclic aromatic hydrocarbons
Abstract Responses to structured questionnaires administered to farmers and housewives in southwestern part of Nigeria revealed that 39 plant species were in use for various purposes in the expressed belief that they possessed bioactive properties.
Abstract The volume of information resources potentially available in the globe is massive; hence it becomes necessary to examine available information resources for academics research activity in the academia. This study, therefore, examined the perception of academics on availability of information resources for research productivity in federal universities in Nigeria. Descriptive survey research design was adopted. The Multistage sampling technique was used to select 1,057 academic staff ...
Abstract This study was carried out to determine the serum auto-antibody levels as primary markers and immunological correlates
Abstract This thesis discusses the development, design, fabrication and testing of spectrally selective beamsplitting absorption filters which can decouple quantum and thermal convertors to improve conversion of the total solar spectrum to useful energy.

ABSTRACT Titanium dioxide or titania (TiO2) being one of the most promising semiconductors for many photoelectrochemical applications, its utilization remains typically confined to ultraviolet (UV) light absorption because of its wide band gap (3.2 eV for anatase and 3.0 eV for rutile), where by UV only accounts for 4-6% of the solar radiation. There is a need to shift the absorption threshold of the UV-region response of TiO2 into the visible region (accounts for ~45% of the total energy of...
ABSTRACT Juttadinteria albata is a leaf succulent plant species endemic to the southern Namib in the Succulent Karoo in Sendelingsdrif near the Orange River. The proposed strip mining for diamonds at NAMDEB‟s new Sendelingsdrif mine may contribute to the loss of up to 39% of J. albata population. This may increase the risks of extinction for J. albata and species which may be interacting with it. The aim of the study was to investigate the biology of J. albata for ecological restoration po...

Abstract The progression of HIV infection to AIDS and then to death can be considered as a Markovan stochastic process. Disease progression can be broken down into a finite number of intermediate states, based on CD4 counts. The four states of the Markov process of HIV/AIDS progression are commonly defined as: S1: CD4 count > 500 cells/microlitre of blood; S2: 350 < CD4 count ≤ 500 cells/microlitre of blood; S3: 200 < CD4 count ≤ 350 cells/microlitre of blood; S4: CD4 count ≤ 200 cells...
ABSTRACT The aim of this study was to determine the physicochemical, nutrients, predominant microflora mainly looking at lactic acid bacteria and spoilage bacteria in Oshikundu samples collected from Omusati, Oshana, Ohangwena and Oshikoto regions. Oshikundu is brewed from pearl millet (Pennisetum glaucum L. R.Br.,) meal locally known as Mahangu, malted sorghum (Sorghum bicolor L. Moench), bran and water. Oshikundu pH ranged between 3.33 ± 0.127 in Oshana region and 3.60 ± 0.014 in Oshikot...
