The quest to boost dietary protein production from readily available and affordable sources is ever increasing in developing countries. The indigenous edible Pleurotus species (oyster mushrooms), which grow naturally on wood wastes, are potential protein supplements. However, little information is available on the usage of selected tropical trees for optimum mushroom cultivation. Therefore, this research was designed to investigate the growth and yield of oyster mushrooms on sawdust of s...
ABSTRACT The Akosombo dam is Ghana‟s main source of energy. Considering the current increase in the demand for electricity in the country, where an increase in demand implies more pressure on the dam, it is therefore very important to investigate the tail behaviour of the water levels of the dam. This is necessary because the level of water in the dam determines the amount of electricity generated. The study investigated this problem using Univariate Extreme Value Theory. Both the Generaliz...
ABSTRACT BACKGROUND: Hearing loss makes a large contribution to the global burden of disease, which substantially adversely affect social and economic development in communities and countries. Due to this, WHO therefore promotes surveys and gathers data for measuring the burden of deafness and hearing impairment. At KBTH, data on the prevalence of hearing impairment is lacking. There is therefore the need for accurate prevalence studies to be carried out in Ghana to enable health organization...
Conventional protein ingredients are expensive, thus necessitating the use of alternative sources of the nutrient. Feather Meal (FM) is high in Crude Protein (CP) but poorly digested by monogastric animals due to the presence of keratin. Poultry requires exogenous enzymes to break it down to its constituent amino acids. Information on digestibility of CP of FM in broilers is scanty. Therefore, ileal CP digestibility of FM supplemented with protease in broiler chickens was investigated. ...
Unsustainable forest land use practices have resulted in land degradation in the northern part of Nigeria leading to low crop yield. Agroforestry is a viable option for reversing dwindling crop yields through proper soil management practices. There is notably no sufficient published information on the contributions of agroforestry to food production in Katsina State. The practices of agroforestry and its potential to slow down the pace of soil degradation and boost food production in Ka...
Nigeria has a population estimated at about 183.5 million people with an average annual growth rate of about 2.75% {United Nations Environment Programme (UNEP, 2012). In order to adequately cater for this population, there is the need to diversify the economy from its perennial mono-economic status depending mostly on crude oil to multi-economic structure with the development of more sectors especially the industrial and agricultural sectors. Industrial revolution in Nigeria has been gra...
Life depends on the Earth's thin layer of soil. This natural body supports plant life in varying degrees of efficiency depending on its productivity potential and nutrient status. Without soil, there would be no plants without plants, there would be no food; and without food animals could not survive. Thus, soil is the beginning of the soil-plant-animal food chaim
The level of Cd, Co, Cu, Mn, Ni, Pb and Zn in fish and sediments of Rivers within the Kaduna South Jndustrial Zone were determined by flame atomic absorption spectrophotometry. The HN03 - I-1202 digestion .. .. system was used to digest the fish sample far trace m etals determination. Tire HN03 - H202 digestion method gave good recoveries which vCiries within 80-95% for Cd, 85-97% for Co, 81-99% for Cu, 79-97% for Mn, 81-93% for Ni, 87- 98% for Pb Clnd 77 - 98% for Zn in a fish smnple. T...
The toxicities of single antibiotics: ciprofloxacin, azithromycin, sulfathiazole and amoxicillin and their quaternary mixtures in different ratios were examined on three organisms Staphylococcus aureus, Bacillus cereus and Micrococcus luteus all isolated from Nworie River from three different points including the point of effluent discharge of a hospital. Toxicity of antibiotics and mixtures was assessed using inhibition of total dehydrogenase assay method. Result obtained from the study...
Studies on toxicological and sedative effects of Datura innoxia plant parts (leaf, seed, stem, pod and root) on Clarias gariepinus fingerlings were conducted under laboratory conditions using the static bioassays and continuous aeration. The aim was to develop an effective anaesthetic from an indigenous plant material that will be available at low cost to aquaculturists and which would be non-toxic to the fish and consumers. The active ingredients and their compositions in the plant par...
The word is not interested in the storm you encountered but did you bring the ship in? It's is not the time a man spends in planning, it's the faith and confidence he put in his planning that really counts. Investigation has revealed that the economic base of Nigeria base on the crude oil. Hence there is every need to take a critical look into the production pattern of this product as to ascertain the trend direction to enable us understand the progressive or regressive direction of th...
This research work describes a study that used measles disease data collected through Knoema health surveillance system to evaluate univariate time series method namely; autoregressive integrated moving average (ARIMA). The data obtained from 1980 to 2016 were used as modeling data and forecasting samples, respectively. The performances were evaluated based on three metrics: mean absolute error (MAE), mean absolute percentage error (MAPE), and mean square error (MSE). A low normalized BI...
This research is about time series analysis and number of babies at birth in Abuja, between 2000-2017 using a monthly data. The box-Jenkin auto regressive integrated moving average (ARIMA) model was estimated and the best fitted model is ARIMA 1,1,1 with Bayesian information criteria (BIC) of 7.580, R2 of 0.402 and with P-values of the perimeters of the model less than 0. 05. The model was further validated with L-Jung Box text with residual been white noise. The mode was use to obtain ...
The thesis examined the socio-economic and environmental challenges of the emerging slums settlements in the Federal Capital City, Phase II Abuj a (the study area). The study identified the failure of the authorities to provide adequate, safe and affordable housing and basic services for the teeming population of the study area as a fundamental factor responsible for the emergence and development of slums in the study area. The study assessed the socio-economic characteristics of resident...
The involvement of Listeria monocytogenes in bacterial meningitis and spontaneous abortion in some towns in northern Nigeria was investigated. Three hundred cerebrospinalfluid (CSF) samples, 300 blood and 300 placenta swab samples were collected from meningitis and spontaneous abortion patients in the study area of Bauchi, Jos and Kano. Three hundred nono (a fermented milk product) samples were also collected from milk hawkers at various locations in the study areas. The samples were in...
