TRANSPORTATION SYSTEM AS A CLIMATE MITIGATION STRATEGY FOR THE GREATER ACCRA METROPOLITAN AREA (GAMA)

ABSTRACT In many cities across the globe, transportation has been a major catalyst for economic growth and for the progress of human societies. However, as an activity that is largely dependent on the combustion of fossil fuels, on-road urban transportation has fast become one of the most important sources of anthropogenic-induced Greenhouse gases (GHGs) which are known to contribute to climate change. The causes and effects as well as adaptation and mitigation strategies for climate change h...

Micro-Finance and Poverty Alleviation of Rural Agricultural Households in the Hohoe Municipality

ABSTRACT Even though great progress has been made towards achieving the Millennium Development Goals by reducing poverty, people continue to live in extreme poverty and more than two thirds of the world poor reside in rural areas. As a result, spatial inequality in development still exists between rural and urban areas due to lack of economic growth and effective policies for rural development. In order to examine microfinance and poverty alleviation in the Hohoe Municipality, the study empl...

PREVALENCE AND RISK FACTORS OF HEARING LOSS AMONG PEDIATRIC PATIENTS AT A TERTIARY TEACHING HOSPITAL IN ACCRA

ABSTRACT Background: Hearing loss is the most frequent hearing deficit in both adult and pediatric populations, affecting more than 250 million people in the world. The consequences of hearing impairment are diverse and include severe impairment, often resulting in a reduced ability to communicate, delay in language acquisition, economic and educational disadvantage, social isolation and stigmatization. However, these consequences can be reduced by early detection together with appropriate au...

QUANTITATIVE EVALUATION OF PRINCIPAL COMPONENT ANALYSIS AND FISHER DISCRIMINANT ANALYSIS TECHNIQUES IN FACE IMAGES

ABSTRACT Face recognition is an attractive field in enhancing both the security and the image retrieval activities in the multimedia world.

Chemical and Nutritional Evaluation of Extruded Complementary Foods from Blends of Fonio (Digitaria Exilis Stapf) and Cowpea (Vigna Unguiculata L. Walp) Flours

Abstract Complementary foods were formulated from fonio and cowpea, indigenous cereal and legume grains respectively. Both fonio and cowpea grains were prepared into flours. Blends of 50:50, 60:40 and 70:30 (w/w) fonio and cowpea flours respectively were prepared. The blends were conditioned to 22% moisture content (dry basis) by adding calculated distilled water and 5% vegetable oil was thoroughly mixed with each blend. The blends were separately extruded using a single screw extruder at 140...

SPECIATION OF INORGANIC ANTIMONY IN POLYETHYLENE TEREPHTHALATE (PET) BOTTLED WATER USING HYDRIDE GENERATION ATOMIC ABSORPTION SPECTROPHOTOMETRY

ABSTRACT Antimony (Sb) is a regulated drinking water contaminant that has been found to leach from polyethylene terephthalate (PET) plastic containers into the waters stored in them. The common inorganic species of antimony in water are Sb(III) and Sb(V), with the former being more toxic and the latter being more soluble. In order to assess the extent to which waters stored in PET bottles are contaminated with inorganic Sb and to further examine the effect of typical storage conditions on mig...

PHENOLIC OXIDASES IN GALL DISEASE OF MILICIA SPECIES

ABSTRACT Milicia regia and M . excelsa are inva.lua.iDle plant species in Ghana for their durable timber. Their numbers are however dwindling. Efforts by the forestry department to establish plantations have been unsuccessful due primarily to attack by Phytolyma species, resulting in gall formation. Phenols and phenolic oxidases appear to be important in the defence mechanisms of some plants as well as in wound healing and regulation of growth in these plants. Thus, they may be natural resist...

INTELLIGENT FIRE DETECTION SYSTEM USING MOBILE WIRELESS NETWORK

ABSTRACT To protect lives and valuables against colossal loss due to fire outbreak In any society, provision of proper safety measures is sine qua non.

Occurence, Civersity and Antimicrobial Susceptibility of Listeria Species From Retail Raw Beef and Goat Meat in Port Harcourt, Nigeria

ABSTRACT Listeriosis has emerged as a disease of public health importance because of its clinical severity, high fatality and challenges to its control including resistance to antibiotics. Outbreaks reported in developing countries including Nigeria were associated with consumption of meat and meat products. However, previous work on Listeria in Nigeria focused on environmental samples. Hence, the need to ascertain the presence of Listeria in meat and their response to antimicrobial agents. ...

Performance Evaluation of Linac Systems: Analysis of a Five Year Quality Assurance QA/QC Data

ABSTRACT The main objective of radiotherapy is to increase therapeutic ratio (ratio of tumor control probability to the normal tissue complication probability) with minimal exposure to the personnel. In order to achieve this, the performance of the LINAC must be optimized toobtain the desired treatment result. The data collected on the equipment must be investigated retrospectively and extensively to assess the actual performance to check if it is functioning within the required standard....

Pore pressure detection and risk assessment of OBL oil field, offshore Niger delta, Nigeria

ABSTRACT The Niger Delta is a prolific petroleum sedimentary basin in the Gulf of Guinea and is posed with a major challenge of overpressure development in many of its fields. Integrated study, utilising 3D seismic data and well logs from four wells, namely; OBL_1, OBL_2, OBL_4 and OBL_5 was carried out in the offshore Niger Delta. The study aims at evaluation of structural influences on pressure development, detection of overpressure zones and consequently examining the risk involved in dril...

THE MOLECULAR CHARACTERISATION OF GIARDIA LAMBLIA IN GHANAIAN CHILDREN

ABSTRACT Diarrhoea is among the six major diseases that causes death among children below age five worldwide. It is also a major cause of morbidity and mortality among children below age five in Ghana. Giardia lamblia is among the major enteropathogen causes of diarrhoea in Ghana. Most studies in Ghana on detecting G. lamblia use microscopy and enzyme linked immunosorbent assay. There is not much data on the molecular epidemiology of Giardiasis in Ghana. This study was conducted to determine ...

ASSESSMENT OF THE CONSUMPTION TRENDS FOR GRASSCUTTER MEAT IN GA- WEST MUNICIPALITY AND DEVELOPMENT OF A THERMAL PROCESS SCHEDULE FOR CANNED MINCED GRASSCUTTTER MEAT

ABSTRACT The objectives of this study were to assess the consumption trends of grasscutter meat among consumers in Ga-West Municipality, to determine the thermal process parameters (cooking time and sterilization temperature, i.e F0 values) of canned minced grasscutter meat, to evaluate consumer acceptability of canned minced grasscutter meat and to assess the quality changes of canned minced grasscutter meat during storage. A cross sectional survey was conducted to establish the consumption ...

ANTIBACTERIAL ACTIVITIES OF THREE MEDICINAL PLANTS ON ORGANISMS ASSOCIATED WITH DENTAL PLAQUE

ABSTRACT The antimicrobial properties of plants have shown promise for development of new drugs which might aid to overcome the increasing challenge of resistance and also the toxicity of the currently available antibiotics. Hence, the aim of the study was to investigate the antibacterial activities of Sida acuta, Anthocleista nobilis, and Zanthozylum leprieurii on clinical isolates of Streptococcus mutans and Streptococcus sanguis and two reference strains: Streptococcus mutans (ATCC 700610)...
