Four experiments namely Experiment I (M1 generation/dosage response study), Experiment II (M1 generation/field study), Experiment III (M2 generation) and Experiment IV (M3 generation) were carried out at the University for Development Studies, Tamale, Ghana, from June to July, 2014; August to November 2014; December 2014 to March 2015 and May to July 2015, respectively. Treat...

Petrographic and whole rock geochemistry was carried out on core samples from the Akwaaba Deposit of the Chirano Gold mine. The Akwaaba deposit is one of eleven gold the Sefwi belt and the Kumasi basin, in the Proterozoic terrain of Ghana. The area is made up of metavolcanic rocks intervened by metasedimentary rock. The geochemical data indicate that the rocks are high in SiO2, Al2O3 and low in K, and Rb. The rocks are tholeiitic in nature and plot in the arc field of Nb/TH versus Y...

Most farmers in the Northern Region of Ghana are unaware of other NPK formulations such as NPK 20-10-10, 20-20-20, 17-17-17, 23-10-10 and 23-10-5 but the most commonly used one is NPK 15-15-15. Pot and field experiments were set-up at the University for Development Studies (UDS) in the Guinea Savanna Zone of Ghana from January to April (Dry season) and June to October (Rainy season) respectively, to study the growth and yield response of maize to the application of NPK fertilizer formulations...

In this paper, we present an algorithm for Residue Number System (RNS) implementation of RSA cryptography based on an existing RNS division algorithm. The proposed algorithm and that of the state of the art were written in C++ programming language to compare their efficiency with respect to execution time. Experimental results show that our algorithm can encrypt and decrypt text without loss of inherent information and faster than the state of the art. It also offers firm resistance to Brute-...

The power of social media such as Twitter, Facebook, Instagram, LinkedIn, etc. in our daily lives cannot be underestimated. Governments have been toppled and countries destabilized as a result of sentiments expressed by citizens on social media. In this paper, we show that mining Twitter Follower/Friend network structure and data can be a powerful method to recognize the needs, sentiments, opinions and interests of the citizenry. Hierarchical clustering and Partition around Medoids were used....

Perturbation analysis of Hilbert linear systems arising in applications is reported. This paper shows the impact of error bound in relation to the perturbation of the linear system. The goal is to bound the relative error of A𝒙 = b when both the right-hand side (RHS) vector b and the coefficient matrix A are perturbed slightly and to determine the relevance of small residual vector. We considered a Hilbert system for the conditioning due to its unique sensitivity to perturbation. From our nu...

Background: The study examines the spatial distribution of low birth weight by the ten administrative Regions in Ghana using Area to Point Kriging method. Low birth weight babies, defined by World Health Organization as babies born at term who weigh less than 2.5 kg is an important indicator of reproductive health and general health status of population. The incidence of LBW is quite high in the sub region which has a public health concern. Methods: The study used a data set based on a Multip...

In this paper, we introduce a new two-parameter deformation of the classical Gamma function, which we call a (p,k)-analogue of the Gamma function. We also provide some identities generalizing those satisfied by the classical Gamma function. Furthermore, we establish some inequalities involving this new function.

Tuberculosis (TB) is of great public health concern affecting one third of the world’s population regardless of all the interventions put in place to control it. The objective of this study was to assess the factors that affect TB treatment in the Bole District. A cross sectional descriptive study was conducted with 95 TB patients made up of 25 defaulters and 70 completed treatment TB patients. Structured questionnaire was used to collect data from the study participants. The quanti...

Background: Severe malaria anaemia in the semi-immune individuals in the holo-endemic area has been observed to occur at low parasite density with individual variation in the responses. Thus the following has been thought to be involved: auto-immune-mediated mechanisms of uninfected red blood cell destruction, and host genetic factors to explain the differences in individual responses under the same malaria transmission. In this study, the extent of red blood cell (RBC) destruction in differe...

Background: Malaria anaemia is still a major public health problem and its pathogenesis still unclear. Interestingly, the progression of anaemia is at relatively low parasitaemia with some mortality in the semi-immune individuals in the endemic areas despite adequate erythropoietin (EPO) synthesis. A recent study has shown that treatment with exogenous anti-erythropoietin (anti-EPO) antibodies (Ab) of infected mice gives protection against malaria infection, suggesting an important role for a...

In this paper, a nonlinear Mathematical model is proposed to study the dynamics of HIV/AIDS in a variable size population involving two groups of infective with different behavioral patterns and an infecting AIDS group. Basic Mathematical and epidemiological implications of the model, like the basic reproduction number and its sensitivity indexes with respect to its parameters, are derived. The basic model is modified into an optimal control problem by incorporating three controls, namely; Inf...

Background: Severe anaemia (SA), intravascular haemolysis (IVH) and respiratory distress (RD) are severe forms of Plasmodium falciparum malaria, with RD reported to be of prognostic importance in African children with malarial anaemia. Complement factors have been implicated in the mechanism leading to excess anaemia in acute P. falciparum infection. Methods: The direct Coombs test (DCT) and flow cytometry were used to investigate the mean levels of RBC-bound complement fragments (C3d and C3...

Polytechnics in Ghana are part of the higher institutional network responsible for training high quality multi-skilled units of human capacity relevant to the national need of the Ghana. This paper empirically examines the management, delivery and the challenges of polytechnics in Ghana. A cross-section design was used as well as multi-stage sampling technique. In addition, both qualitative and quantitative methods of data collections and analysis were also used. The study showed that the go...

This paper examines the links between sexual maturation and menstrual management and dropout and attendance among adolescent girls in Ghana using the four northern regions as a case study. It focus was to examine specifically public management of school girl’s sexual maturation and menstrual hygiene practices and how these affect school dropout and attendance. A multi-site survey was conducted using Purposive, simple random, accidental sampling technique to select the respondents and via that...

Early marriage before the age of 18 years in Ghana is a violation of a constitution of Ghana and a number of international human rights conventions. However, for many young girls in the Northern Region, marriage is perceived as a means of securing their future survival and protecting them. Girls are forced into marriage by their families while they are still children either in school or out of school in the hope that marriage will benefit the girls and their families both financially and soci...

The government of Ghana has used many strategies including the Capitation Grant, the School Feeding Programme and recently the distribution of free school uniforms to pupils in basic school to improve enrollment and attendance in basic schools in Ghana. The Capitation Grant and the School Feeding Programme were not directed first at improving enrollment and attendances of pupils in basic schools, but it had unintended positive effects on enrollment and in many cases attendance in the rural c...

Fura is a millet-based spontaneously fermented dumpling produced and consumed in parts of West Africa, particularly Nigeria, Burkina Faso and Ghana. From eight (8) traditional fura production sites in northern Ghana, lactic acid bacteria (LAB) and yeasts were isolated, characterized and identified using genotypic methods. These included (GTG)5-based rep-PCR fingerprinting, sequencing of the 16S rRNA gene, multiplex PCR by means of recA gene sequence comparison and sequencing of D 1/D2 region ...
