Aspects of the Community Ecology of Waterbirds in Mole National Park

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...

Karyotypes of some Tropical Reduviidf and Cytotaxonomy of Reduviidae (Hemiptera : Heteroptera)

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...

Cashew Processing And Quality Indices

ABSTRACT Cashew is made up of the nut attached to the apple (false fruit) both of which have nutritional significance and economic value. Evaluating the changes that occur during growth and maturation as well as processing w ill help to optimize quality. This is what the study involved. Compositional and physical changes were monitored in six cultivars o f cashew (apple and nut). Local cashew trees were selected randomly after flowering. Collection o f samples commenced after fruit set and at...

Extraction, Purification And Partial Characterization of The Sweet Modifying Glycoprotein Miraculin from Richardella Dulcifica.

ABSTRACT In the present study miraculin, a non-nutritive taste modifier from the tropical plant, Richardella dulcifica has been purified to homogeneity. It was extracted from the pulp of the fruits in 0.5M NaCl and purified at ordinary temperatures by a three step chromatographic process namely; Hydrophobic interaction chromatography, (HIC), Ion exchange chromatography, (IEC), and Gel filtration chromatography (GFC) respectively. The relative molecular weight (Mr) of purified miraculin was a...

A Probability Projection of Male and Female Life Expectancy of Inhabitants Living in Ghana. A Case Study of People Living in the Accra Metropolitan Area

ABSTRACT This thesis is an educational piece which deals with methods and decision-making ways of detecting for life expectancy in the sub-Saharan region of Ghana precisely the Accra Metropolitan area. The data was picked from the archives of the district health directorate of Accra Metropolitan area. A secondary data was used the variables of interest includes age, number of deaths and population and this was done by searching for the age data of the given period and matching it to the numb...

Heat Transfer Analysis of A Proposed Fuel Assembly For Supercritical Water Reactors Under Star CCM + CFD Code

ABSTRACT Accurate knowledge and understanding of heat transfer characteristics near and above critical conditions is crucial to the successful design of the SCWR. Many studies, both numerical and experimental assessments have been conducted on bare tubes and simple geometries like annuli. However, heat transfer performance studies of the fuel assemblies for SCWR are scarce. Thus, there is still a lack of understanding of heat transfer performance in the fuel assembly designs for SCWR. Moreov...

Longitudinal Analysis of Cereals Yields in Ghana

ABSTRACT The aim of this study was to investigate cereal crop yields in Ghana. Specifically, this research determines whether there is a significant difference in the yields across the ten regions in Ghana and also finds out the evolution of crop yields among the regions. Data on two major cereal crops (Maize and Rice) produced and consumed in Ghana was attained from Ministry of food and Agriculture (MOFA). Multivariate Analysis of Variance (MANOVA) and Linear Mixed model (LMM) were employed...

Hydrochemistry And Stable Isotope Assessment of Ground Water And Surface Water, Bongo District, Upper East Region Ghana

ABSTRACT The hydrogeochemical data of groundwater and surface water of Vea dam water of the Bongo District in the Upper East Region of Ghana were examined to determine the main factors controlling the groundwater chemistry and the resultant water type formed in order to determine the suitability of the water for different uses. Conventional graphical methods combined with multivariate statistical analysis are the main methods applied to groundwater and surface water hydrochemical and stable ...

On The Geometric View of Pentagram Integrals of Polygons Inscribed in Non degenerate Conics

ABSTRACT The Pentagram map is a well notable integrable system that is dened on the moduli space of polygons. In 2005, Richard Evan Schwartz introduced certain polynomials called pentagram integrals (Monodromy invariants) of the pentagram map and dened certain associated integrals, the analogous rst integrals. Schwartz further studied in 2011 with S. Tabachnikov on how these integrals behave on inscribed polygons. They discovered that the integrals are equal for every given weight of polygon...

Cattle as Potential Reservoir for Parasitic Zoonotic Diseases in the Lower Manya Krobo District in the Eastern Region of Ghana

ABSTRACT The transmission of zoonotic gastrointestinal parasites in cattle is dependent on the availability of intermediate hosts, poor sanitation and principally, the husbandry and management practices of cattle. The research work was aimed at studying cattle as reservoirs for parasitic zoonotic diseases in the Lower Manya Krobo District of southern Ghana. Microscopic examinations were done on stool samples to determine the prevalence and intensity of egg counts among cattle (N = 486) sampl...

Synthesis Of Novel Atimalarial And Antitubercular Isonicotinohydrazides

ABSTRACT Malaria and tuberculosis (TB) though curable and preventable, remain serious public health problems globally, with devastating consequences. Co-infection of these two deadly diseases worsens the situation and particularly makes treatment very difficult. While the current mainstay for malaria treatment, artemisinins, may gradually lose their potency due to the development of resistance by P. falciparum, M. tuberculosis has developed Multi-Drug Resistance (MDR) and Extensive Drug Resis...

Effect Of Chloroquine On The Induction Of Rat Uterine Peroxidase By An Oral Contraceptive

ABSTRACT Uterine peroxidase has been induced in immature female rate with estradiol and anovlar 21. Anovlar 21 is a steroid contraceptive containing 4 mg. norethisterone acetate (a progestin)t and 0.05 mg. ethinyl estradiol (an estrogen) per tablet. Maximum enzyme activity was found to occur 24 hours after oral administration of the contraceptive. The increased peroxidase activity accused by the eonbined steroids was inhibited by the administration of aycloheximide and puromycin (inhibitors o...

Studies On The Screening Of Some Ghanaian Plants For Fungitoxic Activity Against Five Fungal Pathogens

ABSTRACT The effect of the aqueous and methanol extracts of 12 Ghanaian plants belonging to 10 families on some aspects of the physiology of Sclerotium rolfsii, Helminthosporium sp., Aspergillus niger, A. flavus and Fusarium oxysporium were investigated in vitro in either liquid broth or agar medium amended with varying dilutions (undiluted, 1:1 - 1:5 v/v) of the extracts. Comparatively higher fungistasis against Sclerotium rolfsii and Helminthosporium sp. were found in both aqueous and metha...

The Role Of Traditional Birth Attendants In Promoting Maternal And Child Health Delivery In The Central Gonja And Yendi Districts.

ABSTRACT Maternal and Child Health Care (MCH) has been a challenge to government, NonGovernmental Organisations (NGOs,) service providers and beneficiaries in all developing countries. In fact, it is an area on which a lot of government resources are expended to with the ultimate goal of reducing maternal and child mortality. Majority of the people in developing countries live in rural communities, most of whom do not readily access proper health care. It was in the light of this that the stu...

Radiation Preservation Of Smoked Guinea Fowl (Numida Meleagris) Meat For Enhanced Shelf Life

ABSTRACT Guinea fowl “(Numida meleagris) production is the”main basis of livelihood to many Ghanaians with substantial “role in nutrition and food security.”Due to the nutritional quality of guinea fowl meat, it has resulted in processing of the meat into various shelfstable and ready-to-eat” meat “products, such as”smoked, grilled or fried meat. However, the current traditional guinea fowl meat processing methods do not always guarantee a prolonged “shelf life and quality of ...
