Abstract The campus of Ashesi University Collage has a unique architecture which creates a relaxing feeling for the people who work there or visit it. Even though this is true for most spaces on campus, there are some spaces on campus which have a few design issues like the confined spaces and the lack of natural light. This has caused a dull effect on the people using these spaces as they use them. The location being examined in this project is a staircase which has a low ceiling and little ...
ABSTRACT To communicate effectively between two people there must be some set of rules, conventions, symbols and grammars agreed upon. This set is know as language.
ABSTRACT The need for a robust and secured access control system, using a suitable algorithm is highly inevitable to forestall daily online, hackers that are responsible in defrauding people of invaluable information and transaction worth billions of dollars in the process.
ABSTRACT Schistosomiasis is one of the prevalent Neglected Tropical Diseases (NTDs) in Cross River State, Nigeria. Its transmission is associated with bathing, swimming and swamp farming especially in endemic communities. Previous studies on prevalence have focused on parasitological detection of infected persons and the effects of environmental and socioeconomic factors on exposure to schistosomiasis. However, spatial variations in the prevalence of the disease in endemic communities have r...
ABSTRACT In a survey of children living in South Western Nigeria . plasma levels of a nti -MSP119 antibodies were not associated with patent parasitemia. Anti -MSP1 ,9 antibody titres correlated positively with age, indicating that development of antibodies to MSP1'9 may depend on long -term exposure to parasites.
Abstract An entry length is always observed before laminar flow is achieved in fluid flowing in a conduit. This depends on the Reynolds number of the flow and the degree of smoothness of the conduit. This work examined this region and the point where laminar flow commences in the context of flow through conduit packed with porous material like beads, of known porosity. Using some theoretical assumptions, it is demonstrated that permeability varies from zero at wall–fluid boundary to maximu...
ABSTRACT Indiscriminate disposal of electronic wastes (e-wastes) in Nigeria is on the increase. The release of hazardous substances from these wastes may have harmful consequences on the environment and public health. In Nigeria, there is dearth of information on environmental contamination and genotoxicity of e-wastes, and the mechanism of genetic damage. This study was designed to investigate the level of contaminants in soil, plant and well water; potential in vivo and in vitro cytogenoto...
ABSTRACT Classification is the process of finding a set of models that distinguish data classes to predict unknown class label in data mining. The class imbalance problem occurs when standard classifiers are majority-biased while the minority class is ignored. Existing classifiers tend to maximise overall prediction accuracy and minimise error at the expense of the minority class. However, research had shown that misclassification cost of the minority class is higher and should not be ignore...
Abstract In many traditional societies, beliefs and taboos influence human behaviour towards the natural environment. Such beliefs and taboos are informal institutions where norms rather than official laws determine land use and nature protection in general and wildlife in particular. The present study on beliefs and taboos of the people of the northern periphery of the Korup National Park is an attempt to reveal how norms influence their relation to the environment. A total of 195 household...
ABSTRACT Many practical seepage and drainage problems can be studied by constructing flow nets for section with a single permeability, however many natural soil deposits are more or less stratified often with horizontal bedding that make horizontal permeability much greater than the vertical.
Abstract This work has investigated the corrosion behavior of low carbon steel subjected to four different modes of iso-thermal heat treatment and then immersed in a neutral buffer corrosive medium containing carbonate and chloride ions.The low carbon steel material was cut into twenty small pieces of length 18±2mm, put in groups of five and subjected to: Annealing, Hardening, Normalizing and tempering, each corresponding to an iso-thermal mode of treatment. The samples were ground and poli...
ABSTRACT In spite of the fact that vehicles and pedestrians constitute important urban traffic, conceptual explanations and investments have focused more on vehicular than pedestrian traffic and activities. This study was carried out to examine pedestrian volumes and patterns of flow, factors influencing decision to walk, and pedestrian level of safety in Ikeja, Lagos. Data on the socio- economic characteristics, landuse and street maps of Ikeja were collected from relevant ministries. Seven...
ABSTRACT The efect of therma-extrusion processing of white yam (Dioscorea rotundata) and bambara nut (Vigna subterranean) on some selected exwe parameters of residence time, throughput and moisture content were investigated in this study. Both yam and bambara nut were processed into meals of 750 pm and 500 pm respectively. Extrusion was carried out following a three variable response surJace methodology using a Box Behnken design. Blend of yam meal and Bambara nut meal at ratio 80:20 respect...
ABSTRACT The immune status of children under 15 years in the Southwestern region of Nigeria against measles virus was determined using the neutralization test with a view to assessing the herd immunity to the virus in these communities. A total of 256 serum samples collected from children were tested by the beta method of neutralization. Forty (15.6%) of these samples were found to be positive at a titre of 1:256, 35 (13.7%) at 1:128, 36(14.1%) at 1:64, 37(14.S0h) at 1:32. 38 (14.8%) at 1:16,...
ABSTRACT Cassava (Manihot esculenta Crantz) peel is one of the solid wastes produced as a consequence of cassava processing. It is low in protein but contains a large amount of carbohydrate, causing an environmental problem with disposal. In order to add-value to this major cassava processing waste and also reduce its resultant environmental pollution, this study investigated the effect of submerged fermentation using Trichoderma viride ATCC 36316 on the protein content and amino acid profile...
