MULTIVARIATE ANALYSIS OF FOOD PRICES IN GHANA

ABSTRACT This study is concerned with the evaluation of the price levels of food items in various markets across Ghana. The objective was to determine the main dimensions along which to identify specific markets in which items are high-priced and those that are low-priced. To this end, data on prices in 2008 of fifteen food items in 100 selected markets from all the regions of the country were obtained from the Statistical, Research and Information Directorate of the Ministry of Food and Agri...

COPEPOD ABUNDANCE AND IMPACT OF SELECTED HUMANINDUCED STRESSORS ON CALANOID COPEPOD IN THE COASTAL SEA OF GHANA

ABSTRACT According to the UN, sea surface temperatures (SST) are increasing at alarming rates and the oceans are increasingly polluted by anthropogenic activities. This thesis sought to determine how two pollutants – cadmium (Cd) and pyrene (PY) interacting with sea surface warming affect copepod egg production (EP), mortality and recycling of ingested food through faecal pellet (FP) production. A field study was conducted on transects established on the Western, Central and Eastern Coast T...

FINGERPRINTING OF BLACK POD DISEASE-RESISTANT THEOBROMA CACAO L. ACCESSIONS USING MICROSATELLITE MOLECULAR MARKERS

ABSTRACT Black pod is a disease of Theobroma cacao L. and can cause up to 100% losses in crop yield. Breeding for resistance can reduce or prevent the incidence of the disease. This study was therefore designed to assess black pod disease resistance in 205 accessions of five populations; ‘T’ clones, progenies of ‘T’ clones, Amazonia, Series II hybrids and a control population of susceptible accessions by the leaf disc method and genetic fingerprinting using 13 mTcCIR microsatellite mo...

IN VITRO ANTI LEISHMANIAL ACTIVITY OF SOME SELECTED MEDICINAL PLANTS IN GHANA

ABSTRACT Leishmaniasis is a parasitic infection that affects mostly tropical and sub-tropical regions of the world and caused by diverse pathogens that belong to the genus Leishmania. The pentavalent antimonials developed in 1945 are still first line treatment drugs for both cutaneous and visceral leishmaniasis while amphotericin B is a second line treatment drug. These treatments come with toxic side effects even at effective doses and the lack of vaccine demand the urgent need for new anti ...

PROCESSING OPTIONS FOR FAT CONTENT REDUCTION WHILE MAINTAINING SENSORY CHARACTERISTICS OF KOOSE

ABSTRACT  Consumer preference for low fat content foods is increasing over the years. High fat content in most fried food products is a major factor affecting consumer acceptance of fried products today. Low-fat food products are becoming more popular, due to the health risk associated with the consumption of high fatty foods. Koose is a widely consumed street food in Ghana. It is prepared either by wet or dry milling of soaked and dehulled cowpea seasoned with salt, pepper and onions. ...

ASSESSMENT OF THE IMPACT OF MANGANESE DEPOSIT IN BOTSWANA KGWAKGWE MINE ON THE ENVIRONMENT

ABSTRACT The Kgwakgwe manganese deposit is 4 km southwest of Kanye village (70 km west of Gaborone, Capital City) in Botswana. The manganese deposit is surrounded by about 30 boreholes which supply the entire Kanye population with water, through pipes into each home. Weathering of manganese and other elements from rocks (due to the geology of the area) leach into underground water within the catchment. The study assessed the quality of drinking water from the boreholes and estimated their com...

MOLECULAR CHARACTERIZATION OF GROUP A ROTAVIRUSES DETECTED FROM ASHAIMAN IN THE GREATER ACCRA REGION OF GHANA (2014-2016)

ABSTRACT Group A Rotaviruses (RVAs) are the most important etiological agents of acute gastroenteritis (AGE) in children less than 5 years of age. Mortality resulting from RVA gastroenteritis is higher in developing countries than in developed ones, causing a huge public health burden in global regions like Africa and South East Asia. The aim of this study was to investigate the strains of RVAs causing AGE in children less than 5 years of age in Ashaiman after the introduction of the Rot...

SPATIO-TEMPORAL ANALYSIS OF ROAD TRAFFIC ACCIDENT ON THE ACCRA-TEMA MOTORWAY: CAUSES AND RISK FACTORS

ABSTRACT  Road transport faces a host of challenges with road traffic accidents (RTA) being notable among them and RTAs are well-known for causing most deaths in many countries. The main objective of this study was to analyse the spatio-temporal pattern of RTAs on the Accra-Tema Motorway and the extent to which motor vehicle drivers contribute to accident on the motorway. The Haddon Matrix and the Systems Theories were applied to give a holistic view of RTAs. The cross-sectional research des...

EXTREME VALUE ANALYSIS OF TEMPERATURE AND RAINFALL: CASE STUDY OF SOME SELECTED REGIONS IN GHANA

ABSTRACT  Rainfall and temperature are important climatic factors for crop production and affects humans’ basic needs such as health, shelter, food and water in Ghana. However extreme rainfall causes flooding which can lead to loss of lives, properties among others. Extreme temperature also causes drought, hot and cold spells among others which have adverse implications on human beings and agriculture. It is therefore important to know about occurrences of such extreme events and thei...

ESTIMATION OF GLOBAL SOLAR RADIATION IN SELECTED SYNOPTIC STATIONS IN GHANA

ABSTRACT The global solar radiation potential of eight Synoptic Meteorological Stations in Ghana was reported in this study. Five stations were selected from the Northern belt, mostly made up of Sudan Savanna and Guinea Savanna regions of Ghana and the other three stations were selected from the Middle belt, mainly Deciduous Forest and Coastal Savanna regions of Ghana. AngstromPrescott Sunshine Hour Model was employed to estimate the global solar radiation for these stations. The daily sunshi...

ATTITUDE AND COMPETENCE LEVEL OF BASIC SCHOOL TEACHERS IN THE TEACHING OF ICT IN CAPE COAST METROPOLIS

The use of ICT has impacted to some extent on almost every facet of our daily activities. Students of today grow up with an array of technology, both at home and at school. Educators and governments have also devoted huge resources to the provision of technology in the learning environment. Despite the increase in ICT tools in Ghanaian basic schools, some teachers do not use them in their teaching. The general purpose of the study is to examine the attitude and competence level of basic schoo...

MATERNAL HEALTH AND WOMEN'S RIGHTS IN THE GA DlSTRlCT

ABSTRACT E-r. year at least half a million women die from pregnancy related causes of which., 99% come from developing countries. The root cause of this situation IS due to the fact that the decision-making power women regarding the right to decide on how many children to have and when (whether) to have them, the use of contraceptives and the right to refuse sex with their husbands have been circumcised by socio-economic conditions within which they live. The study data were based on primary ...

DETECTION OF TICK-BORNE RICKETTSIA SPECIES IN TICKS COLLECTED FROM CATTLE IN SOME SELECTED SITES IN GHANA

ABSTRACT  Ticks continue to facilitate the spread of pathogens globally, thereby influencing the health of both humans and animals. Ticks have been documented to infest animals including pets and livestock, transmitting bacterial pathogens including Rickettsia species. It is common to find many Ghanaian households rearing animals, thus increasing the risk of infection. It is therefore important to identify the present tick species and determine their potential to transmit diseases. This...

VALIDITY ASSESSMENTS OF COMPUTERIZED AUDIOMETRY A CASE INVOLVING THE KUDUwave5000 AUDIOMETER AND THE ACEScreening DEVICE

ABSTRACT Background: Technological progress in the construction of personal computers, has offered the possibility of conducting hearing tests with a computer program. Computerized audiometers can be designed for manual, automatic and self-administered hearing testing. Aim: The study investigated the validity of the ACEScreening device as a self-administered hearing screening test and the KUDUWave5000 audiometer as an automated diagnostic audiometer. Methods: The population for this study con...

Petroleum Exploitation or Human Exploitation? An Overview of Niger Delta Oil Producing Communities in Nigeria

This paper examined the impact of petroleum exploitation on the environment of the Niger Delta oil producing communities in Nigeria. This is in furtherance of the understanding that human beings are at the centre of concerns for sustainable development. The paper observed that there was need for the adoption of measures that would provide a reasonable degree of protection of ecological and human environment from the activities of the oil industry in Nigeria.
