Abstract It is well established that the forces between nucleons are transmitted by meson. The quantitative explanation of nuclear forces in terms of meson theory was extremely tentative & in complete but this theory supplies a valuable point of view . it is fairly certain now that the nucleons within nuclear matter are in a state made rather different from their free condition by the proximity of other nucleons charge independence of nuclear forces demand the existence of neutral meson as ...
ABSTRACT Data centres use a lot of power, consumed by two main usages: power required to run the actual equipment and power required to cool the equipment. Usage of electricity results in the production of electric and magnetic fields (EMF). Even though electricity is useful in human lives, there have been reported cases of adverse health effects from EMF generated from its use. Because the use of electricity is ubiquitous and plays a vital role in society’s economy, the possibility of har...
ABSTRACT Beach sands are known host of different heavy minerals, which occur mostly as placer deposits and are of great importance to the electronics, metallurgy, medical, defense, and automobile industries. Typical examples of such heavy minerals are the rare earth-associated minerals (e.g. monazite, bastnaesite, xenotime and euxenite). Some of these rare earth elements-containing ores are known to occur in association with naturally occurring radioactive uranium (U-238) and thorium (Th-232)...
Abstract The petrochemical industry is a major contributor of industrial air pollutants which are known to have dire consequences on human health and the environment, neccesitating research into their dispersion and transport. The objective of the study, therefore, is to simulate the dispersion and transport of pollutants emitted during the processing of crude oil by the Tema Oil Renery in the Greater Accra region of Ghana using the California Pu (CALPUFF) modeling system. This thesis couples...

Abstract A year-long investigation has been carried out on atmospheric particulate matter (APM). Elemental composition,mass concentration, sources contributions and their fingerprints were determined in APM samples collected, in Agbogbloshie scrap market, between May 2010 and April 2011. PM2.5 and PM102.5 size fractions of APM were collected 24-hourly on 47 mm diameter nuclepore filters of pore sizes 0.4 µm and 8 µm respectively, using the Gent sampler. Gravimetric analyses were carried out...

ABSTRACT Ghana is in the process of converting its fuel from Highly Enriched Uranium (HEU) to Lowly Enriched Uranium (LEU) even though the HEU fuel is not fully spent, thus the handling of the irradiated fuel is in the offing. Irradiated fuel consists of radioactive fission and activation products generated in the nuclear fuel which are hazardous to personnel, environment and the public. As a result, the knowledge of the dose rate will aid in safe guarding the process of core conversion. Two ...
