ABSTRACT A solar-powered adsorption refrigerator using activated carbon1methanol.pair was designed and fabricated. The refrigerator has three major components: collector,condenser, and evaporator. A 3 mm thick flat glass was used as flat plate collector. The condenser was made of spirally 'coiled copper tube immersed in pool of stagnant water contained in a reinforced concrete tank. The evaporator was fabricated from standard ' 15.6, rnm diameter copper tubing. The activated carbon used as ad...
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 research project, the various nail were subjected to six environments so as to check the effect of the environments on corrosion of the nails. Two sets of nails were used; normal nail and concrete nail. Six of each type while the other not coated. The research was carried out in the physical chemical laboratory of the institute of management and technology. The environments used are acidic solution, alkaline solution, salt solution, boiled water, air medium and lubricating...
ABSTRACT Ghana Research Reactor-1 core is to be converted from Highly Enrich Uranium (HEU) fuel to Low Enriched Uranium (LEU) fuel in the near future; a storage cask will be needed to store the HEU fuel. Notwithstanding the core conversion process, it is also important for the facility to have a storage cask ready when the fuel is finally spent to temporarily store the fuel until permanent storage is provided. Winfrith Improved Multigroup Scheme-Argonne National Laboratory (WIMS-ANL), REactor...

Abstract The purpose of this research is to explore and understand the factors that enable some career women successfully balance both career and family roles. This research adopted an exploratory research approach into finding the contributing factors through online surveys, questionnaires, and interviews. The research revealed that career women in Ghana balance their work and family roles under four main themes; external help, proper planning, maintaining good relationships with supervisors...
ABSTRACT This capstone project idea is to develop a system called FarmConnect—a mobile application platform that connects investors with smallholder farmers who are seeking funding for their farm operations. Such funding will help the farmer operate at full capacity hence increasing the level of food security in Ghana. FarmConnect will be able to provide interested investors with concrete data that will inform their decision to invest in a chosen smallholder farmer. Also, an example farmer ...
ABSTRACT The research examined the integration and participation of the elderly in the socio-economic development of Harare Metropolitan Province (HMP). It targeted religious denominations, industry and commerce, non-governmental organizations, tertiary institutions, state enterprises and parastatals and a local authority. The research identified serious stigmatization of Old Persons (OPs), leading to their ostracism by HMP institutions in particular, and ordinary citizens in general. The les...
1.0 INTRODUCTION Housing which can be defined as collective structures in which mankind is housed and where he carries out his daily economic, social and commercial activities, which encompass man’s immediate physical surrounding services, facilities and all available social amenities. Provision of housing has been a major challenge since the 21st century to all sovereign states across the world. Adequate housing provision has been hindered over the years, by various factors w...
Abstract The teaching of mathematics has been viewed classically at all onsets and specific patterns of work teaching methodologies versus the consequent content analysis have been invaluably developed at various research phases. The study looks critically at mathematics as a subject and its relative relevance within the performance environment and it entrenches the whole concept of the same to further evaluation. Study after study has at all time given us concrete evidence of the concept of ...
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 ...
Christian Ethics is ethics which considers the specific situation, gathers the facts and uses the principles (commands and doctrine) and values to be found in Christianity. In this way, morality is used to describe our principles or convictions about what is right and wrong and our ultimate values. As seen in it, moral philosophy tries to study those principles and values, analyzing them critically and working out how we make decisions. Christian ethics also follow what is called “Applied o...
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...
INTRODUCTION Aquaculture is one of the fastest growing food producing sectors in Agriculture and fish is among the most traded food commodities world-wide accounting for 17 per cent of global intake of animal protein (Food and Agricultural Organization, 2014). Fish is an aquatic and a source of high-quality animal protein that could be harvested from capture or culture fishery (Olele et al., 2008). Fisheries expert needs a medium where they can culture fish in a confined and controlled envi...
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...
