Design, Construction and Assessment of an Improved Hybrid Charcoal-LPG Cookstove

ABSTRACT Globally three (3) billion people use inefficient cook stoves and fuels and the smoke emitted from these cook stoves leads to 4.3 million deaths per year. In Ghana, 70% of households use traditional cook stoves and solid fuels whose emissions lead to 17,000 deaths every year with 50% of them being children under five (5) years of age. Whilst the negative health impacts of the emissions generated by these cook stoves is increasingly being recognized, there are limited varieties of imp...

Quality Evaluation Of Artisanally Produced Honey Sold On Ghanaian Markets

ABSTRACT Honey is the most commercialized bee product in Ghana. It is utilized by all age groups and religious bodies with increasing demand. However, the production, packaging and handling has been associated with unsanitary and unhygienic practices with scanty documented information on production practices. Most of the artisanal honey are also mainly retailed in places where environmental conditions and handling practices do not meet fundamental food hygiene standards. This study sought to ...

Evaluation Of Some Nutraceutical Properties Of Lesser Known Functional Foods In Ghana

ABSTRACT Functional foods are foods that possess other health benefits apart from their regular nutritional benefits. A functional food may contain nutraceutical properties, which have components, responsible for curing or preventing a disease or disorder. There are several indigenous foods in Ghana that have been purported to possess functional properties. The claim to functionality of some of these indigenous foods are based on folklore but the scientific backing to these claims may not be ...

Comparative Study Of The Prevalence Of Hearing Loss Among Hepatitis B Virus Infected Patients And Uninfected Volunteers: A Case Study

ABSTRACT Background: Worldwide the hepatitis B virus (HBV) infection is considered a major public health concern, infecting about two billion people. Annually, the disease accounts for about one million deaths. The prevalence of the disease is considered high in Africa, affecting about 8% of the population in West Africa and between 5 to 7% in Southern, Eastern, and Central Africa. Ghana has a high prevalence rate of 12.3% with most infected persons seeking medical attention at the terminal s...

Modelling Rates Of Inflation In Ghana: An Application Of Autoregressive Conditional Heteroscedastic (Arch) Type Models

ABSTRACT The research is based on financial time series modelling with special application to modelling inflation data for Ghana. In particular the theory of time series is explored and applied to the inflation data spanning from January 1965 to December 2012 which were obtained from the Ghana Statistical Service. Three Autoregressive Conditional Heteroscedastic (ARCH) family type models (traditional ARCH, Generalized ARCH (GARCH), and the Exponential GARCH (EGARCH)) models were fitted to the...

Quasiconvex Functions On Time Scales And Applications

ABSTRACT  In this thesis, the notion of quasiconvex functions on time scales and some properties are established. The subdifferential for quasiconvex function on time scales is presented as well as some properties regarding quasiconvex function. Some Jensen’s inequalities for quasiconvex functions on time scales are also given with some applications. The study again proves that Jensen’s inequality holds for quasiconcave monetary utility function in conjunction with convex, concave, quasi...

Temporal Modelling Of Currency In Circulation In Ghana

ABSTRACT  The Currency in Circulation is the outstanding amount of notes and COIns circulated in the economy and are the most liquid monetary aggregate. In this study, data on monthly Currency in Circulation obtained from the Bank of Ghana database was modelled using both SARIMA model and Regression model with ARIMA errors. The results revealed that ARIMA (0, 1, 1)(0, 1, 1)12 model was the best SARIMA model for the Currency in Circulation. This model has the least AIC of -372.16, AICc of -37...

Stakeholders Participation As A Determinant Of Effective Implementation Of Land Use Plans In Tamale Metropolis In Northern Region Of Ghana

ABSTRACT  The study focused on the assessment of stakeholders participation as a determinant for effective land use plans implementation in the Tamale Metropolis of Northern Region of Ghana. Primary data was then collected from households and institutions and analyzed. The study revealed that those factors such as leadership qualities, transparency, resources availability and centralization of decisions affect successful stakeholders’ participation in implementation of land use plans. The ...

Application Of Linear Programming To Media Selection Planning: A Case Study Of Mobile Telecommunication Network (Mtn)

ABSTRACT Generally this research used Linear Programming techniques to investigate the budgetary allocation of MTN Company for effective media selection planning. The problem was formulated as a linear programming technique by using the available data obtained from the company and other media sources. Mathematical software which embodied the simplex algorithm techniques such as Quantitative Manager for Business version 3.2 and Linear Programming Solver version 5.2.2 were used to solve the res...

Comparative Analysis Of Sarima And Setar Models In Predicting Pneumonia Cases In The Northern Region Of Ghana

ABSTRACT  Acute respiratory infection (ARI) range, in spectrum, from mild colds and coughs to life threatening pneumonias. ARI particularly pneumonia is the major cause of morbidity and mortality among young children under five in developing countries with Ghana not an exception. In this study, we compared the linear SARIMA Model and the nonlinear two regime SETAR Model in predicting pneumonia cases in northern region of Ghana. Data on monthly pneumonia cases obtained from the Tamale Teachin...

The Application Of Queuing Theory To Customer Service At Selected Branches Of The Standard Chartered Bank Ghana Limited

ABSTRACT This thesis investigates the Application of Queuing theory to customer services at selected branches of the Standard Chartered Bank in Accra. The problem investigated was to determine among other things whether the customer service points of the bank functions well without bottlenecks or undue delays. That is this thesis intends to investigate, (a) If the bank current system of operation at the customer service points is satisfactory. (b) If not what changes are required to improve t...

Photocatalytic Degradation Of Organic Dyes Using Zinc Oxide Nanoparticles.

ABSTRACT Nanocrystalline zinc oxide particles were synthesized via sol-gel method using zinc acetate as precursor. Calcination temperature was varied to determine its effect on particle size. The resultant samples were subjected to X-ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), UVvisible and Scanning Electron Microscopy (SEM) characterization techniques. X-ray diffraction results showed nanocrystalline wurtzite ZnO particles with crystallite size ranging from 16 nm to 30 nm resp...

Survival Analysis Of Male And Female Hiv/Aids Patients In Northern Region - A Kaplan & Meier Approach

ABSTRACT   Acquired Immune deficiency Syndrome (AIDS) is a disease caused by a virus known as Human Immunodeficiency virus (HIV). This virus attacks a person's immune system (white blood cells) and as such weakens the immune system and making the person vulnerable to opportunistic diseases e.g. tuberculosis, diarrhoea, to mention a few.  HIV was first diagnosed more than twenty years ago and up to now there is no known cure for the disease. The rate at which HIV is spreading in sub-Sahara ...

Misclassification Cost Sensitive Learning For Predicting Gonorrhea Infection Status In Ghana

ABSTRACT Gonorrhea, which is one of the most frequently reported sexually transmitted infection is caused by a bacterium called Neisseria gonorrhoeae. This disease can causes a serious public health problem worldwide, with about 88 million new infections occurring each year. Failure to treat this disease can result into pelvic inflammatory disease (PID), chronic pain and also damage the female reproductive organ. In males it can lead to reduced fertility and sterility. In developing countries...

Investigating Factors Influencing Variation In P. Falciparum Invasion Phenotyping Assays

ABSTRACT Malaria caused by P. falciparum, is the most life-threatening human parasitic disease, claiming over 400,000 deaths from about 200 million cases in 2017. Despite the yet unsuccessful efforts in the quest for an effective malaria vaccine, antigens expressed in the erythrocytic stage of P. falciparum represent highly promising vaccine candidates given their natural exposure to the immune system. Understanding the mechanism of erythrocyte invasion by P. falciparum mainly during active c...
