ABSTRACT The development of a linearized thermistor-based thermometer circuit with a thermistor and a diode as the temperature probing elements is here reported. The circuit is effectively that of an op amp based logarithmic amplifier, which takes its input from another inverting op amp circuit having a thermistor in its feedback loop. The performance of the circuit is demonstrated experimentally and has been found to have a linearity error of less than 0.2%. The accuracy analysis of the circ...
ABSTRACT The study sought to find out the effects of Computer-Assisted Instruction on the academic achievement of Senior High School (SHS) students in Plane Geometry in the West Akim Municipality. It specifically investigated whether Computer-Assisted Instruction has any effect on gender as far as the academic achievement of students is concerned. The quasi experimental group design (or the non-equivalent group design) was employed as the research design. Students from two comparable classroo...
ABSTRACT Multiwalled carbon nanotube (MWCNT) has been found to produce structural changes in Calf Thymus-DNA (CT-DNA). The interaction or binding of the multi-walled carbon nanotubes (MWCNT) was investigated in order to discover if it brings about any significant changes of the DNA double helix using CD spectra of the CT-DNA at two concentration levels of MWCNT representing an increasing MWCNT/DNA molar ratio. In addition, spectrophotometric titrations between MWCNT and CTDNA were carried ou...
ABSTRACT Five feeds, designated A, B, C, D and E, were used in the culture of Oreochromis niloticus (L) to evaluate and compare their effects on growth performance, feed conversion ratio (FCR), fish production, survival rate and profitability in commercial tilapia farming in Ghana. Feed A contained only wheat bran and was used as the control; Feeds B, C and E were formulated from wheat bran, fishmeal, maize, palm oil and premix vitamins in varied proportions. Feed D was a commercial fish feed...
ABSTRACT Background: Molluscum contagiosum (MC) infection is caused by a pox virus and the virus is probably passed on by direct skinto-skin contact which may affect any part of the body. There is anecdotal evidence associating facial lesions with HIV-related immunodeficiency. This study was aimed to determine the prevalence and associated risk factors of Molluscum contagiosum infection among PLWHAs attending ART clinic at the University College Hospital, Ibadan, Nigeria. Methods: This is a ...
ABSTRACT Hypertension is a public health challenge due to its high prevalence, and is a major risk factor for cardiovascular diseases. Hypertension is a complex disease resulting from an interaction of genes and environmental factors. Inconsistent association between polymorphisms of the renin angiotensin aldosterone, the atrial natriuretic peptide systems and hypertension has been reported among various ethnic groups, but not for the Efiks and Ibibios in south-south Nigeria. This study was ...
ABSTRACT The global ageing population is increasing in number and in proportion, although at different rates in different parts of the world. Ageing involves biological, psychological, economical and social change throughout the life cycle of an individual. The social status of the aged in a given society reflects the political, economic and traditions ofthat society. In Ghana, family-based support systems for the aged were very effective in the past. However, there are concerns on the effect...
Abstract The aim of this study was to investigate the morphology of Macrotermes bellicosus present on some parts of the University of Ibadan and to determine the effect of the saliva of termites on the strength of termitarium. Termites were collected from 8 termitaria on Parry Road, University of Ibadan and characteristics morphometrics were measured using stage graticules (10mm) on Microscope. Amylase analysis was conducted to determine the activity of the saliva content in the termitarium ...
ABSTRACT There are striking statistics and issues about women, their sexual rights and HIV/AIDS around the globe, in Africa and Ghana. Women’s exposure to the danger of contracting HIV/AIDS is reinforced by their lack of the right to negotiate for safe sex. The study focused on the Krobo and Gurene ethnic groups in Ghana. It sought to assess the gender roles among the Krobo and Gurene people and their implications for HIV/AIDS infection. Also, it identified some of the sociocultural practic...
ABSTRACT Antimicrobial resistance is fast becoming a global concern in both healthcare settings and in the community due to the rapid emergence of multi drug resistant organisms. High proportions of enterobacteria have developed resistance to the commonly prescribed antimicrobial drugs. Comprehensive data upon which to advocate control interventions are scanty. Hence this study determined the Molecular Epidemiology of ESBL producing enterobactericeae from three Tertiary Hospitals in Southern ...
ABSTRACT The essential role of radiotherapy is to ensure detection and treatment of breast cancers using appropriate doses, these seem not to harm patients under review. Unintended detriments in the treatment and the risk of secondary cancers are mostly associated with delivering much higher doses than planned dose. This study focused on using phantoms for the determination, and comparison of planned doses with actual doses delivered to the breast, during radiation treatment. Adelaide phantom...
ABSTRACT This study looked at the challenges facing the Ministry of Education and other stakeholders and efforts being made to address the ICT situation in some schools based in rural areas in the Atwima District of Ghana. The design for the study was a descriptive survey. The sample was made up of 105 people drawn from 6 selected basic schools in the Atwima District of Ashanti Region. The main instrument used for the study was questionnaire. After pilot testing , reliability co-efficients of...
ABSTRACT Despite the fact that a variety of improved traditional African complementary foods have been developed from cereal-legume blends (1,2), the traditional products that are a leading cause of protein-energy malnutrition, still remain the primary weaning foods, especially in rural communities, largely because of the high cost of improved complementary foods, The ingredients for low-cost complementary foods must be derived from dietary staples available and affordable in the region of in...
ABSTRACT Herbal medications are becoming increasingly popular but a most-extraordinary claim by traditional/herbal medical practitioners relates to a Gram-positive bacterium, Staphylococcus, which has been depicted as a deadly sexually transmitted disease that manifest in the form of worms and other symptoms; with contributory roles including infertility, sexual dysfunction and impotency. They further boasted that they are the only ones that possessed the remedy (herbal) for the Staphylococc...
ABSTRACT Thermal conductivity. toughness, cleavability tensile and bending strengths of Khqa senegalensis (Oganwo), Nauclea cliderrichii (Opepe), Triplochiton scleroxylon (Arere), Pycnanarhus angolensis (Akomu), Albizia zygia (Ayunre) grown in Ogun State, Nigeria were investigated to obtain preliminary data on these properties to guide utilization. The thermal conductivity was measured using fully automated unitherrn 6000 Guarded Hot Plate (-170 to 550'~) while the tensile and bending strengt...
