ABSTRACTLongitudinal data are common in various sectors where repeated measurements on a dependent variable are collected for all subjects. Missing data pattern are caused when most planned measurements are unavailable for some subjects. The dropout process may cause three missing values mechanism, namely: Missing Completely at Random (MCAR), Missing at Random (MAR), and Missing Not at Random (MNAR). The missing values have influence on quantitative study that can be serious, leading to bias...
This study examined the impact of dumpsite on soil and plant quality in Mpape, Abuja FCT. The study employed both transect and quadrant techniques in collecting soil and plant samples. The soil samples were taken in both rainy and dry season for three months each at the depth of 0-30cm using soil auger. A total of forty-eight soil sample and thirty-two plant samples were collected, totalling eighty samples in and around Mpape Dumpsite and taken to Abuja Environmental Protection Board (A...
Advances in several key communication and information technologies are worth tracking for their impact on interactive health communication and ability to meet .customers' demands. One of these technologies is the inte1net. It is based on this that this research work is cal1'ied out to dete1mine the level at which the internet has been able to improve the delivery of healthcare services in the healthcare delivery system in Nigeria. An explanatory research methodology was adopted in the c...
ABSTRACT Shai Osudoku, a District known as the cradle of Dangme land and Krobo culture, and a predominantly farming area, is experiencing the sprawl phenomenon. Agricultural lands, which serves as the main source of livelihood to majority of the inhabitants in the District, has been encroached by the process of urban sprawl. A major result of this phenomenon is a growing sprawl at the fringes of some of its major towns. This study focuses on assessing the impact of urban sprawl on agricultur...
Glutathione Peroxidase (GPx) family of enzymes plays important roles in the protection of organisms from oxidative damage. GPx converts reduced glutathione (GSH) to oxidized glutathione (GSSG) while reducing lipid hydroperoxides to their corresponding alcohols or free hydrogen peroxide to water. This study was conducted to investigate the possible effects of temperature in vivo on Glutathione peroxidase (GPX) oxidative activity in fish tissues.An adult fully grown cat fish, (the African flath...
Human dietary intake comprises three macronutrients (protein, carbohydrate, and lipid) and a large number of micronutrients (vitamins, minerals, antioxidants, etc.). Good health rest, in part, on an adequate and balanced supply of these components to the human body [1 ]. Supplies and consumption of oils and fats are generally described in terms of seventeen commodity oils, four of 'which are of animal origin and the remainder of which are derived from plants. This description does not i...
Abstract As an aid to the control o f the schistosome host snails, effective bioactive materials namely cassava, cocoyam, and sweet potato (Domeh, 1998), sugarcane and peels, all in their raw and processed states were tested in simulated natural environment experiments. The experiments were conducted using ‘biopots’ traps designed using a pot with few small windows created on the sides to allow easy diffusion o f test materials to reach the water body to attract the snails It was observe...
ABSTRACT Cochlospernum tinctorium A. Rich was investigated for its chemical constituents and its antiplasmodial activities. The chemical constituents of petroleum ether, dichloromethane and ethyl acetate extracts of the rhizome of the plant were successively studied. The in vitro antiplasmodial activities for petroleum ether, dichloromethane, ethyl acetate, ethanol and water extracts as well as the isolated compounds were determined. Three compounds isolated from the dichloromethane extract ...
ABSTRACT Drying, a process for food preservation involves subjecting a food commodity to high temperatures that aid in the removal of moisture thereby making the food shelf stable. The objective of this study was to design a greenhouse type solar dryer that would be used for the drying of cassava and other foods and evaluate the characteristics of the dried products. The rationale behind this study was that open sun drying has been the method of drying over the centuries but it is subjected ...
ABSTRACT The eicosanoids are a group of oxygenated unsaturated 20-carbon chemical compounds produced from arachidonic acid (AA), that mediate almost every step in the inflammatory process naturally. Some of the eicosanoids are anti-inflammatory while others are proinflammatory. Desmodium adscendens, a medicinal plant used by local herbalists to manage asthma, had been shown to be anti-anaphylactic in vivo, and to modulate AA metabolism in vitro. In this work, the anti-inflammatory properties...
ABSTRACT The eating habits, nutrient intakes and nutrition knowledge of one hundred and forty adolescent students from four secondary schools in the central region of Ghana were investigated. Instruments used for the data collection included questionnaires, food records, anthropometric measurements and observations. Data obtained were analysed using a computer and descriptive analysis was used to present the data. Jellife's anthropometric reference data, Kaufman's weight classification and Bo...
ABSTRACT The study sought to demonstrate how credibility claim costs without the consideration of claim frequency and claim severities underlined by different risk profiles underestimate claim costs or premiums charged policyholders by non-life insurance companies. We used secondary data of non-life marine insurers in Ghana, claim histories that range from the period of 2013 to 2018. The claim histories included claim sizes, claim counts and policy counts. Bühlmans-Straub Credibility theory...
Abstract Background: Acute respiratory infections (ARI) remain a leading cause of morbidity, mortality, and economic loss globally. Until recently, human coronaviruses (HCoVs) have been mainly associated with mild upper respiratory tract infections. The 2003 outbreak of severe acute respiratory syndrome coronavirus (SARS-CoV) and cases of Middle East respiratory syndrome coronavirus (MERS-CoV) since 2012, illustrate the potential of coronaviruses to cause severe disease. Thus, it was necess...
ABSTRACT Mole National Park is the largest and oldest national park in Ghana. With a large number of species of birds, mammals and reptiles, the number of tourists in Mole National Park keeps increasing and therefore creating room for human disturbance in diverse ways. Using the total area count method, this study established the species of waterbirds at Mole National Park and determined the seasonal variations in their diversity and abundance in four permanent wetlands from August 2015 to F...
ABSTRACT Data is presented on 2n~numbers of some forty- six (46) species of Tropical Reduviidae collected in Southern Ghana, West Africa. This information is combined with existing data and together analyzed and discussed. It was found that the roccgnised morphological plasticity of Reduviidae extends to the diploid numbers as well. However a level of cytological organization was found to exist within the family. Three autosomal-Chromosome groups: 20A, 24A and 23A are proposed. It has emerged...
