Abstract Some inequalities involving the q-digamma function are presented. These results are the q-analogues of some recent results.
ABSTRACT This study was undertaken to examine the nature and quantify the magnitude of Genotype by Environment interaction effects on rice (Oryia Sativa L.) grain yield and to determine the most stable and winning genotype (s) in terms of yield stability and performance in two rice producing hubs. The study was conducted at four locations within two rice producing hubs in Northern Ghana on fifteen (15) rice genotypes including a checking genotype GR18 red. A randomized complete block design ...
ABSTRACT The role of weight-for-age babies in the early childhood and its effects on later lives of children cannot be over emphasized. Birth weight according to Murthy (1991) is a key indicator of the incidence of infant mortality and thus, a reflection of the socio-economic development of a country. The main objective is to use statistical models to assess the change in weight of children over time and to investigate whether maternal characteristics such as marital status, educational leve...
ABSTRACT Recent discovery of cutaneous H. ducreyi has complicated the epidemiology of Yaws in endemic countries. Yaws and H. ducreyi ulcers are clinically indistinguishable from each other and some other causes of skin ulcerations. The aim of the study was to isolate and characterize H. ducreyi strains from lesions of children in yaws-endemic areas. Symptomatic patients were first screened with Dual Path Platform (DPP-RDT) Syphilis Screen & Confirm test kit (Chembio, Medford, New York) for ya...
ABSTRACT The water level at a particular time determines the amount of hydro-electrical energy generated by the Akosombo dam. The Akosombo dam serves as the main source of electrical energy in Ghana. This research work sought to estimate and assess the impact of the Bagre Dam as an intervention event on the Akosombo Dam. Daily water level data covering the period 1982 to 2002 which was obtained from the Volta River Authority (V.R.A), Ghana was used in carrying out this study. Empirical resul...
ABSTRACT The study aimed at collecting, characterizing, storing and assessing the ethnobotanical uses of the African rice and its wild relatives collected from the Volta Region of Ghana. It also aimed at detecting the concentrations of mineral elements namely: nitrogen (N), phosphorus (P), potassium (K), iron (Fe), zinc (Zn), copper (Cu), lead (Pb), cadmium (Cd) and arsenic (As) in soils of the different accessions collected. Seven accessions of rice were collected from paddy fields in fourte...
ABSTRACT Crimean-Congo haemorrhagic fever virus (CCHFV) is an arbovirus which belongs to the Crimean-Congo haemorrhagic fever serogroup. It belongs to the viral family, Nairoviridae and genus, Orthonairovirus. Crimean-Congo haemorrhagic fever serogroup and Nairobi sheep disease serogroup both fall under this genus. Viruses from these two serogroups are pathogenic to humans and animals respectively, and therefore have a significant economic impact. Tick species of three genera are known to tra...
ABSTRACT The gametocytocidal effect of antimalarial drugs has become important in malaria research owing to the global quest to eradicate the disease. In Ghana and most parts of Africa, people still depend on herbal medications despite advances in western medicine. However, these drugs lack the necessary scientific assessment. The IC50s of 10 known herbal antimalarial drugs on the Ghanaian market were determined. The development of sexual stages of the Plasmodium falciparum was monitored and...
ABSTRACT Birth weight is one of the key indicators of the health and viability of the newborn infant and a person’s personality. It is desired that birth weight should be in the range of 2.5kg and 4.0kg. Low Birth Weight (LBW) has been defined by the World Health Organisation (WHO) as weight at birth less than 2.5kg. This study considered causal variables of LBW among infants in the Sunyani Municipality and sought to postulate a statistical model for predicting the likelihood of giving bir...
ABSTRACT Regular assessment of weight gain among babies has been a way of assessing their health status and growth. This study assessed the weight gain among babies under different forms of feeding practices for the first nine months after birth. The feeding practices focused on in this study are Exclusive Breastfeeding (EBF), Breastfeeding with water only (BFW), Breastfeeding with any other food including water (BFWO) and Non-Breastfeeding (NBF). Data was obtained from Mampong Babies Home, ...
Abstract Some inequalities involving the (p, q)-digamma function are presented. These results are the (p, q)-analogues of some recent results.
ABSTRACT Extended-spectrum beta-lactamases (ESBLs) are plasmid-mediated enzymes capable of hydrolysing beta-lactams except carbapenems and cephamycins but are inhibited by beta-lactamase inhibitors. Most of these ESBL plasmids also carry genes conferring resistance to several non-beta-lactam antimicrobials. Hence, ESBL-producing isolates limit therapeutic options, contribute to treatment failure, increase morbidity and mortality, prolong hospitalization and increase cost of healthcare. There ...
ABSTRACT Survival analysis has been invaluable in studies involving time to an event. The methods encompassing the idea of Survival Analysis appears to be commended by most researchers particularly in the medicinal, engineering, agricultural and actuarial fields. This paper applied survival methods to promotion data of lecturers in the University of Ghana. The main objective was to identify the factors prominent in facilitating an early promotion of University of Ghana lecturers. The proporti...
ABSTRACT It is known that certain polynomials of degree one, with integer coefficients, admit infinitely many primes. In this thesis, we provide an alternative proof of Dirichlets theorem concerning primes in arithmetic progressions, without applying methods involving Dirichlet characters or the Riemann Zeta function. A more general result concerning multiples of primes in short-intervals is also provided. This thesis also considers problems concerning the existence of odd perfect numbers. T...
ABSTRACT A study was conducted on the growth pattern of the penaeid shrimp, Penaeus notialis, in earthen ponds at the Volta Estuary of Ghana. The ponds were treated with chicken manure at the rate of 0 kg/ha (control), 100 kg/ha, 200 kg/ha, and 300 kg/ha respectively. The culture period was divided into two phases; the first phase covered a period of 90 days and the second phase took 180 days. Growth rates established at the end of the 90 days of culture were 0.04 - 0.13 g/day that resulted...
