ABSTRACT This work deals with the multi-faceted impact of gas flaring on a global scale and the different approach employed by researchers to measure gas flared and its resulting emissions. It gives an overview of methods employed by these researchers in the oil and gas industry, academia and governments in attempt to determine ways of measuring and reducing gas flaring and its emission drastically. This approach so far includes analytical studies, numerical studies, modeling, computer simul...
Abstract This thesis consists of three papers on child labour and schooling in Ghana. The first paper examines the correlates of child labour and schooling, as well as the trade-off between work and schooling of children aged 5-17 years with the 2013 Ghana Living Standard Survey data. A bivariate probit model is used since the decisions to participate in schooling and in the labour market are interdependent. The results show that there is a gender gap both in child work and schooling. In par...
Abstract: Biogas is an alternative source of energy that is produced by methanogenic bacteria through the bio-degradation of organic material under anaerobic conditions. In this study, biogas production from co-digestion of the goat manure (GM) and watermelon peels(WMP) in five mix ratios were evaluated under 38ºC using batch fermentation. In all treatments, physico-chemical parameters such as total solid (TS) and volatile solid (VS), organic carbon, and pH were measure before and after dig...
Sorption and desorption of rifampicin was assessed on three different soil. Sorption mechanism was studied in terms of equilibrium and kinetics at different pH. Linear, Freundlich and Langmuir isotherm models were adopted to study the isotherm. The experimental data were best described by pseudo-second order kinetics (R2 = 1.00). It was observed that rifampicin absorbs better on soil with lowest organic carbon content. Sorption was observed to increase with decrease in aqueous pH and increase...
ABSTRACT An important musical type that supports farmers’ activities at Kpandu and its environs, to ensure their welfare and survival through subsistence farming is agblehawo, a term which literally means “farmers’ music”. This study sought to explain why the s4hewo (the youth), of Kpandu up to date, cling to the performance of agblehawo in the face of other varied forms of music to which they are exposed. To explain this socio-musical behaviour of the s4hewo, the conceptual framework...
Abstract The essence of science education is to produce confident, self-employable, scientifically, and technically sound men and women. Unfortunately, the chemistry curriculum appears not to have achieved much of its objectives. These lapses might have been caused by non-availability and usability of chemistry laboratory facilities for teaching organic chemistry. It is against this background that this study examined the extent of availability and usability of chemistry laboratory facilit...
ABSTRACT Investigations were conducted with four pot and two field experiments on the influence of vesicular arbuscular mycorrhiza (VAM), and fertilization on chili pepper, Capsicum annuum var. tatase (Yoruba) in different cropping systems. All experiments were factorial in a randomized complete block design (RCBD) and each treatment was replicated three times. The first two pot experiments carried out in the Department of Botany and Microbiology, University of Ibadan under natural solar il...
ABSTRACT The study area is bounded by latitudes 5027’N and 5034’N, and longitudes 7025’E and 7035’E. It falls within the Northern Niger delta Basin. The aim of this present study is to evaluate the hydrocarbon potentials of the sediments in the area, determine their age and environment of deposition. To achieve this aim, geochemical analysis (TOC and Rock-Eval) and Palynological studies were carried out on fifteen (15) samples. Results from the analysis indicates that the total organi...
ABSTRACT A two –year (2004/2005) field investigation was carried out on the runoff plots at the University of Nigeria Nsukka farm, to monitor the effects of cover management practices on physical properties, runoff and soil loss in Nkpologu sandy loam soil. The management practices were barefallow (BF), cocoyam (CY) sorghum (SG), legume (CP) and grass (PM), under no-till practice. There was no change in soil texture due to treatments. The treatments generally increased soil organic matter c...
Abstract: Biogas is a methane gas produced through anaerobic digestion fermentation of organic matter. The aim of this study was to determine the optimal mix ratio for biogas production from anaerobic digestion of vegetable waste (carrot and cabbage waste) and goat manure. The experiment was batch operated and daily gas yield from the mixture was monitored for 30 days. The parameters measured were total solids (TS), volatile solids (VS), organic carbon, and moisture content. For the experime...
ABSTRACT This research is aimed at developing a Crop Disease Detection and Control Advisory System which assists the farming community. The idea of developing the system came as a way of mitigating the problems affecting the organization that include poor and slow service delivery in FCC shops when assisting farmers or giving advice to farmers. Farmers from remote areas have to travel long distances to get assistance and be advised on how they can cure certain diseases affecting their plants...
Abstract: Dairy farming complements both food and cash crop farming in Kenya. Due to limited land sizes, smallholder dairy farming is popular and dominates the dairy sector in terms of milk production. Low milk production is a major constraint in Tigania East SubCounty despite the fact that the surrounding Sub-Counties produce high amounts of milk. A survey was carried out in Tigania East Sub-County involving 156 smallholder farmers randomly selected across three agro-ecological zones (AEZ1,...
Abstract: Soil Organic carbon (SOC) is vital to the soil’s ecosystem functioning as well as improving soil fertility. Slight variation in C in the soil has significant potential to be either a source of CO2 in the atmosphere or a sink to be stored in the form of soil organic matter. Location-specific information on soil organic carbon (SOC) helps to identify potential sources and sinks of carbon. However, modeling SOC spatiotemporal changes was challenging due to lack of data to represent ...
Abstract: Improvement of the contribution of the untapped huge goat resource of Ethiopia can be achieved through alleviating constraints and adjusting inefficient production practices which requires knowledge about roles of goat, husbandry practices, production constraints, performance under the prevailing condition and available resources. With this understanding, a survey study on goat production systems of mixed crop livestock (MCL) and Agro pastoral (AP) Farming systems in the rural kebe...
Abstract Seasonal rainfall variability, particularly the uncertainty with respect to the direction and extent that variability will assume in a given season, forms the greatest source of risk to crop production in semi-arid areas of Ethiopia. Equipping vulnerable communities, in advance, with the expected date of onset of a cropping season, is crucial for smallholder farmers to better prepare to respond and manage the uncertainties. Therefore, rainfall prediction, particularly development of...
