A fatigue driving stress that causes damage is presented and used to predict residual life under variable loading. This a function of the applied cyclic (σ), number loading cycles ( n), failure N). It increases with until strength reached when fracture occurs. By determining equivalent or fraction at current load yields same as previous loads, remaining can be predicted. new model derived expended load, logarithm initial load. The cumulative indicates [Formula: see text] for low-to-high...
To identify potential sources of hookworm infections in a Ghanaian community endemicity that could be targeted to interrupt transmission, we tracked the movements infected and noninfected persons their most frequented locations. Fifty-nine participants (29 positives 30 negatives) wore GPS trackers for 10 consecutive days. Their movement data were captured real time overlaid on grid map. Soil samples collected divided into two parts: one determining physical chemical properties other culture...
Artisanal and Small-Scale Mining (ASM) landscapes form integral part of the Land use land cover (LULC) in developing worlds. However, spatial, spectral, temporal footprints ASM present some challenges for using most freely available optical satellite sensors change analysis. The challenge is even profound tropical West African countries like Ghana where there prolonged cloud cover. Whiles very few studies have used Sentinel-2 data to map analysis landscape, none examined contribution...
Increasing effect of climate change coupled with global warming has necessitated the need for mechanical cooling in buildings to provide indoor thermal comfort. Many countries tropical climates, particularly sub-Saharan Africa, use sandcrete blocks constructing building envelopes which have relatively high conductivity. This leads increased heat transmission through walls resulting electricity consumption using air-conditioners. study focused on opportunity minimizing conductivity by mixing...
This study aimed at evaluating the potential biogas production from four main sources, in terms of volume methane for energy and equivalent avoidable carbon dioxide emissions 2020 through to 2030. It was based on projection common livestock poultry manure, possible landfills, wastewater treatment plants, palm oil mill effluent. paper uses sound reliable methodology estimate these major resources, which could lead significant achievement environmental sustainability via generation emission...
Aquatic invasive weeds affect hydrological, ecological, and socio-economic activities on freshwater ecosystems. On the Lower Volta River (LVR) of Ghana, aquatic have been known to be nuisance fishing, navigation, aquaculture, hydropower production other agricultural practices in area. While information spatial temporal distribution would beneficial improving weed management control measures river, such is very scanty. Also, these are also biomass resources, that can transformed bioenergy....
structural applications in the petrochemical, telecommunication, aerospace, and foodprocessing industries. This is due to their excellent corrosion resistance good mechanical properties, such as toughness, ductility, formability (Bain Griffiths, 1927; Jenkins et al. 1937; Zapffe, 1949). However, austenitic structure, these steels have quite low surface hardness poor wear (Bell, 2002; Fewell al., 2000). To improve diffusion thermochemical treatment techniques carburizing (Agarwal 2007; 2000),...
Compressive residual stresses are often induced by mechanical surface treatment such as shot peening for the purpose of improving fatigue life components. Cyclic relaxation compressive stress, however, reduces benefit. For component design and management purposes it is important to be able assess effect their on life. The problem, that phenomenon stress under cyclic loads not well understood. Furthermore, there technical challenge accurately quantifying during operation. difficulties in...
The mechanism for strength development when unbound soils are reinforced with geogrid is not well understood. Research on reinforcement has tended to focus largely improving the properties of little attention influence soil performance. This study investigated effects plasticity index and gradation lateritic enhancement within a soil-geogrid-reinforced composite pavement. Three samples different were compacted tested in without reinforcement. Reinforcement involved incorporating one two...
Urbanisation in Ghana has been associated with significant effects on the land surface temperature which its impacts natural environment. Conventional literature exhibits that urbanisation have concentrated developed world leaving African terrain unattended to. Hence, knowledge and implications Africa for matter is deficient. This study two-pronged a) examines relationship between coupled spatial patterns (b) urban heat island urban-rural gradient Greater Accra region of Ghana. Landsat...
