Comparative Study of Mathematical Models for Ghana’s Gold Production

Sigmoid functions were used to approximate the cumulative gold production in Ghana. The functions examined were the logistic, Gompertz, Gaussian, Probit and the Hill, which were then used to predict into the future. Although all the five approximated models gave a good estimation of the reality, the Gompertz function was identified to give the best approximation of the observed trend of gold production in Ghana. The model was selected based on its high proportion of variance explained (R2 = 0.9402) as well as having the least value in terms of error (RMSE) and information loss (AIC). The model suggested that gold production could escalate to a level of 7040813 Oz in the future. It also showed that, industrial scale production of gold should be possible even after the year 2050 provided the current upward trend of gold production in Ghana continues. Keywords: Sigmoid, Logistic, Gompertz, Gaussian, Probit, Hill, Gol

Evaluation of the effectiveness of Eladi Keram for the treatment of acne vulgaris: a randomised controlled pilot study

Introduction: Acne is a multifactorial and common skin disease which can significantly affect the quality of life of sufferers. In this study, a topical herbal preparation traditionally used in Ayurvedic medicine was evaluated as a treatment for individuals with acne on their shoulders and backs. Methods: Study participants were randomly assigned either to treatment (Eladi Keram) or vehicle control (coconut oil) groups under double blind conditions and instructed on its daily home application. Standardised lesion counting and acne grading were conducted in accordance with US Food and Drug Administration guidelines and with reference to the Leeds Acne Grading Technique. Participants were assessed for severity of the condition at commencement and on day 28 of treatment. Results: The treatment group showed improvements of 42% (p < 0.005) on the Investigators Global Assessment scale, a 60% (p < 0.05) reduction in inflammatory lesions, a 59% (p < 0.05) reduction in non-inflammatory lesions, and a 59% (p < 0.005) reduction in combined lesion count. The control group showed no statistically significant changes for these criteria. Conclusion: This study is the first reported clinical evaluation of Eladi Keram as a treatment for acne and findings suggest that it could be effective in reducing inflammatory and non-inflammatory lesions, warranting further investigation by means of a larger scale clinical trial

Electronic vs. Print Resources: A Survey of Perception, Usage and Preferences Among Central University Undergraduate Students

The study adopted a cross-sectional survey approach to examine the perception, usage and preferences of electronic and print resources among University Students. The study sought to determine the knowledge of students on electronic library resources, their value for electronic and print resources, ascertain the perceived usefulness, perceived ease of use, and intended use these resources. Results from the study indicated that majority 134(57.0%) of the respondents always preferred print resources format for their academic work while 101(43%) occasionally preferred the electronic resource format for academic work. The findings of the study are critical to the implementation of policies and procedures geared toward sensitizing students, faculty and other stakeholders to the benefits of increasing students’ knowledge and use of electronic library resources. The study is envisaged to aid in strategic planning and investments pertaining to these resources and provide recommendations to improve knowledge and use of these resources within university

Effect of Soil Amendment on the Functional and Pasting Properties of False Horn Plantain Flour

There is growing public perception that fruits from fertilized plantain plants have their organoleptic qualities reduced during food preparations. Such perception has the potential consequence of lowering production levels of the commodity in Ghana. To ascertain the veracity of this perception, a study was conducted between July 2012 and March 2015 to determine the effects of different rates of poultry manure, cocoa pod husk and NPK as soil amendments on nutritional composition, physical characteristics and functional properties of plantain pulp flour. The experimental design was a Randomized Complete Block with three replications. Flours from plantain with amended soils recorded moisture contents (8.41 % to 12.08%) which were within the acceptable levels for flours. The flour with the lowest moisture content was produced from plantain with CPH amendment (8.41%). The protein content of false horn plantain flour was however low (3.39 % to 5.27%).The plantain flour starch was not influenced by any of the soil amendments. On the other hand, flour produced from plantain with NPK+PM amendment had low bulk density and low water absorption capacity. Similarly, the false horn plantain flour had lower swelling power values compared to other flours.Flours from plantain with CPH amendment had lower oil absorption capacity. Flour from plantain with PM amendment was more likely to cook faster than the flour from the plantain with the other amendments. Flours from plantain with NPK+CPH amendment would form a more stable paste because of its lower breakdown value. In conclusion, the plantain flours were comparable to known food flours and therefore could be applicable as thickening agents and also find usefulness in fufu powder preparation and baking

Safe use of NSAIDs and RAS-inhibitors at Agogo Presbyterian Hospital, Ghana

Background: Preventable adverse events of medication are an important cause of hospital admissions in the developed world, in which non-steroidal anti-inflammatory drugs (NSAIDs) and renin angiotensin system (RAS-) inhibitors are frequently involved. NSAIDs and RAS-inhibitors are also often used in Ghana. The purpose of this study is to assess whether biochemical monitoring in patients on RAS inhibitors, and co-administration of gastro protective agents (GPAs) in patients on NSAIDs, is done properly in Ghana.Material and methods: Two retrospective cross-sectional studies were carried out at the Agogo Presbyterian Hospital, Ghana, in 2013. In 114 out-and inpatients who are on NSAIDs, the risk for gastrointestinal side effects and the frequency of co-administration of GPAs were determined. In 301 outpatients who are on RAS-inhibitors, the risk for renal dysfunction and the frequency of biochemical monitoring were determined. Fisher’s exact test was used to determine the statistical strength.Results: Co-administration of GPAs was done in 1.8% of patients on NSAIDs. Serum creatinine and potassium monitoring within one month after initiation of treatment with RAS-inhibitors were performed in 6.3% and 3.7%, respectively. Risk factors were neither associated with prescription of a GPA in patients on NSAIDs (p=0.134), nor in performing biochemical monitoring in patients on RAS-inhibitors (p=0.219 for creatinine, p=0.062 for potassium).Conclusions: Biochemical monitoring in patients on RAS-inhibitors and use of GPAs in patients on NSAIDs is poorly performed at the Agogo Presbyterian Hospital in Ghana. Improving the already existing Ghanaian guidelines, especially those for RAS-inhibitors, and encouraging their widespread use among prescribers should be pursued.Keywords: Ghana, Non-Steroidal Anti-Inflammatory Agents, Anti-Ulcer Agents, Angiotensin-Converting Enzyme Inhibitors, Angiotensin Receptor Antagonists, Drug monitorin

Alternative low-cost latrine option for rural and peri-urban communities

The aim of the study was to develop a low-cost latrine that is suitable for use in the rural and peri-urban areas. The study assessed the key capital cost components of three commonly used on-site latrine technologies in Ghana (Ventilated Improved Pit, Traditional pour flush toilet, and Biofil toilet) which was used as basics for the design of a new low-cost latrine option. The study was conducted using field survey and field test. The results of the study revealed that, majority of latrine installation cost comes from pit lining, followed by pit excavation, cover slab, with pipe materials bearing the least cost. It was also found that installing the newly developed toilet technology saves 64 %, 62% and 83% of the cost of the Pour Flush toilet, VIP and Biofil toilet respectively

Regional Integration of Equity Markets in Sub-Saharan Africa

Equity markets in developing and emerging economies have grown in number and importance as a result of financial market globalisation. However, their role in economic growth and development is enhanced if nascent markets are integrated with well-established ones. Market integration, measured by the transmission of returns volatility, is identified across a sample of SSA countries, using a unique dataset. Evidence for potential integration between financial markets in Sub-Saharan Africa (SSA) is found. Spillovers are found across markets, some unidirectional and others bi-directional. However, continued illiquidity and incomplete institutions indicate that an integrated financial community remains premature, and considerable regulatory reform and harmonisation will be necessary for this to succeed

WASH infrastructure and menstrual hygiene management in basic schools: a study in Kumasi, Ghana

Understanding the role of Water, Sanitation and Hygiene (WASH) services on menstrual hygiene behaviors and practices and ultimately on school absenteeism is important to inform policy and practice. This study focused on how the schools’ WASH infrastructure affects Menstrual Hygiene Management. The study was based on data from seven schools in the Weweso circuit, Kumasi-Ghana collected through Focus Group Discussions, key informant interviews and observation of water, sanitation and hygiene (WASH) facilities in the selected schools. Public schools (government managed) did not have adequate provision for menstrual hygiene management and the private schools (individually owned) had better WASH infrastructure/services that provide a better environment for menstrual hygiene management compared to the public schools. The poor WASH infrastructure in basic schools constrain school girls from maintaining good menstrual hygiene practices. The study recommends education on menstrual hygiene management and the incorporation of adequate consideration for menstrual hygiene management infrastructure in basic schools (primary school)
