Abstract: Medicinal plants have been used for centuries to treat diseases. Differences in antimicrobial activities may affected by geographical area and other conditions.This study was carried out to screen the phytochemical composition and antimicrobial activities of leaf,friut and root extracts of U.dioca against pathogenic bacteria and fungus. U.dioca is a medicinal plant which belongs to the family Urticaceae.The Leaf,friut and root of this plant were collected. The phytochemical screeni...
Abstract: The study was conducted to assess dairy production practices, milk composition, and microbial quality of smallholder dairy farms in Kombolcha Woreda, East Hararghe Zone, Oromia Region, Ethiopia. The study was undertaken in purposely selected three rural Kebeles of Kombolcha Woreda (Bilisuma, Tula, and Sibilu) where dairy Farmers from each Kebele were also purposely selected. A sample of households with at least one lactating cow was selected for interview using a simple random samp...
Abstract: In Ethiopia, enset is one of the indigenous root crops widely cultivated in the south and south western parts. Particularly in Wonchi district it is a major source of food and cash income for majority of smallholder farmers. Enset processing and its product marketing is left for women regardless of the tediousness of the process. Though, it is considered as female’s work by the community, concrete evidence about the gender role in enset product market chain is not well documented...
Abstract: The production of copper bears both viable product and by product know as slag which is a challenge to dispose and poses a problem to the environment. BCL holds copper slag is seen as waste which is iron - opulent containing heavy metals which can seep into ground water and affect environment. These metal accumulate in millions of tonnes year after year posing as a threat to the environment and need to be managed to avoid them being harmful. This paper explores metallurgical ways o...
Abstract: This thesis focuses on biological shielding calculations for a 10 MeV Rhodotron electron beam accelerator operating in dual mode to produce a 10 MeV primary electron beam and 7.5 MeV secondary X-rays, generated by hitting an optimized tantalum-73 (73Ta) target with the primary electron beam. The first part of this thesis describes the Rhodotron electron accelerator and its oper ating principle. A model is presented for the transverse optics of a TT-100 Rhodotron accelerator. Potent...
Abstract: ABSTRACT. We conducted larval surveys in habitats located in urban Malindi, Kenya, in 2005 and 2006 with the goal of determining the productivity of unused swimming pools in relation to other habitats. Of the 250 habitats sampled, 66 were unused swimming pools, 93 were wells, 60 were drainage troughs, and 31 were miscellaneous areas, such as septic tanks, swamps, concrete tanks, fish ponds, car-track depressions, and drainage ponds. Anopheles gambiae s.l. was the only anophelines s...
Abstract: Context Tungiasis is a neglected tropical skin disease endemic in resource-poor communities. It is caused by the penetration of the female sand flea, Tunga penetrans, into the skin causing immense pain, itching, difficulty walking, sleeping and concentrating on school or work. Infection is associated with living in a house with unsealed earthen house floors. Methods This feasibility study used a community-based co-creation approach to develop and test simple, locally appropriate, a...
Particulate-filled polymer composites are becoming quite attractive because of their low cost and wide application. Nowadays shells of arthropods and mollusks are widely used as reinforced materials due to their availability and impact mechanical properties. This study focused on theproduction and evaluation of impact strength of snail shell reinforced epoxy composite and as well given concrete information and recommendation on usage with respect to appropriate filler concentration an...
In the sense that the materials involved in this project were capital intensive more especially cement, so in carrying out the work one must have to be careful in the selection and collection of materials to be used in the casting of the concrete.The materials used are coarse aggregate (granite) fine aggregate (sand). The coarse aggregates used in this work were collected from Ishiagu while the fine aggregate was collected in front of the carpentry’s workshop on the campus.The test conform ...
Philosophy of the Department The departmental philosophy is in line with the national philosophy of Nigerian educational information technological aspirations, as it is in line with the establishment of universities of technology in the Country. Our philosophy is to develop high manpower needs that would meet the Nigerian ICT aspirations in such areas as business establishments, through web networking, cybercrimes and terrorism overcoming at both local and international scenes, alleviate fra...

After a turbulent year, the market for non-fungible tokens and digital assets in 2023 is expected to see a period of stabilization as regulation increases and enthusiasm cools, putting an end to its "Wild West" attribute. 2023 is poised to see an increasing amount of NFT platforms providing concrete offerings that user and investors can get benefits equally. 2023 will see NFTs as a building block to create a stronger foundation for Web3 to be built upon. 2023 is showing signs of continued str...
ABSTRACT In this work, models for predicting six structural characteristics and cost of sand-quarry dust blocks were developed. Three model equations namely Scheffe’s simplex lattice design (pseudo component), Scheffe’s simplex lattice design (component proportion) and Osadebe’s model were developed for each property. The properties investigated were Compressive strength, Water absorption and Split tensile strength. The others are Static modulus of elasticity, Flexural strength and She...
ABSTRACT Thin-walled box girder bridges are very efficient structural solution for long-span bridges because of their high torsional resistance, stability, economy, and aesthetic appearance. Though, this type of bridge is not common in Nigeria, it is envisaged that they may offer economic advantages in future high way projects in Nigeria. Analytically, however, the box girder bridge is a very complex indeterminate problem. Therefore, the primary objective of this research was to produce a r...
