ABSTRACT The use of browse tree fodder as supplements to ruminant feeding in the tropics is limited by lack of information on their nutritive potential. A study was carried out to screen eight browse species in Kongwa and Kiteto districts (Acacia mellifera, Acacia senegal, Acacia xanthophloea, Acacia tortilis, Boscia spp., Gliricidia sepium, Leucaena pallida and Melia azedarach) for potential chemical composition, concentration of minerals, and in vitro digestibility potential using chemica...
ABSTRACT Napier stunting (Ns) disease, caused by Rice Yellow Dwarf (RYD) phytoplasma, is a big threat to Napier grass production and food security in Kenya. The disease destroys fodder completely, with a devastating impact on livestock farmers. To control the disease, this study described the four components of Ns-disease pathosystem; phytolasma itself as the causative pathogen, the host plant susceptible to phytoplasma, the insect as a competent vector, and the alternative sources of phytop...
Kenya is endowed with a wealth of natural resources comprising minerals, land, soils, air, forests, wildlife and various other forms of biodiversity. In the recent past, the Country has witnessed increased attention in the exploitation of mineral resources such as titanium, gypsum and gold to just name a few. Exploitation of mineral resources is prone to bio-physical and socioeconomic impacts. Due to regular violent protests by the local population on account of environmental degradation, the...
ABSTRACT The chemical composition of C. lusitanica and E. saligna essential oils was determined and leaf essential oils evaluated for contact and fumigant toxicity, repellence and reproduction inhibition effects against S. cerealella, A. obtectus, S. zeamais and T.castaneum. Bioassays were carried out at temperature of 28±2oC and relative humidity of 65±5% and laid out in CRD with four replicates per treatment. In all bioassays, essential oils were applied at 0.00, 0.05, 0.10, 0.15 and 0.20...
ABSTRACT The University of Ibadan is faced with a persistent challenge of providing adequate students’ housing as a result of explosion in the students’ population in consequence of which the on-and off-campus students’ housing policy was adopted. Existing literature on students’ housing investigated on-campus students’ housing but neglected offcampus students’ housing. This study therefore, conducted a comparative assessment of the on-and off-campus students’ housing in the Un...

ABSTRACT Globally, healthcare systems are experiencing increasing fiscal demographic and consumer pressure. There have been metamorphic changes in the recent past in terms of healthcare delivery. The planning, design and final architectural expression in health care is reflective of the gradual shift in outlook of healthcare institutions from merely treating the sick to a concerted approach to harness healthy living. This has been triggered by globalization, increased expectations of seekers...
ABSTRACT Architectural design is ultimately about the configurations, connections , shapes, and orientations of physical forms. This study seeks to explore the architectural space and then focuses on the "study of effective spatial analysis and integration of functions in large complex buildings". Design begins by generating ideas and transforming them into concrete spatial formations and spaces that are accessible to a wide range of users in large complexes. This study has revealed series o...
ABSTRACT Transportation is an essential need for humanity, be it land, air or sea based. It should devoid of operational handicaps. However, in Lagos State, In-land water based transportation encounters various kinds of impairments ranging from human induced to natural cause. To this end, this study explores the challenges encountering In-land water based transportation system in Lagos state. Adopting survey research design, both secondary and primary data were employed for the study. Second...
ABSTRACT This project work present the alkylating reaction of [Pt2(μ-S)2(PPh3)4] with boronic acid alkylating agents.The reactivity of the metalloligand [Pt2(μ-S)2(PPh3)4] with the boron-functionalized alkylating agents BrCH2(C6H4)B(OR)2 (R = H or C(CH3)2) was investigated by electrospray ionization mass spectrometry (ESI-MS) in real time using the pressurized sample infusion (PSI). The macroscopic reaction of [Pt2(μ-S)2(PPh3)4] with one mole equivalent of alkylating agents BrCH2(C6H4)B{O...
ABSTRACT There are large areas of Nigeria and probably of West Africa that have never been visited or studied by a geologist or geophysicist. Not so in the region surrounding the Benue Trough. This area has repeatedly attracted a lot of attention in the past, and with the advent of plate tectonics the available geological and geophysical data from the region have been interpreted in various ways to suit different tectonic models. No attempt is made here to review the relevant published work o...
Abstract - Igneous intrusives of basic to intermediate (syenilic) compositions in the Lowcr Bcnue Trough had produced contact cffccts which ro.lge from the lowcr albite- cpidotc hornfels to the cordierite hornfels facies on the host sedimentary rocks which vary mainly from pelitic to calcareous pelitic types. Contact effects of low intensity and size were produced by three smaller igneous bodies of basic composition whose thicknesses range from 1 to 3 m. The mineral assemblages of the aureole...
The efficiency of the sewage works depends on the quality and quantity of the influent and the design of the sewage works. Inefficiency of the sewage work has adverse health impact to the aquatic ecosystem. Pollutants can bio-accumulate and bio-magnify in the food chain causing health impact to both human being and wildlife. The main objective ofthis study was to assess the effectiveness of wastewater management system of Njoro industrial sewage works. This study used descriptive resear...
