Farm Management Practices And Its Contribution To Cocoa Yield In The Asutifi North District Of Ghana

ABSTRACT Cocoa has been the most important cash crop in Ghana, contributing significantly to the country’s GDP and providing a significant source of income for a lot of households. The government, in trying to support the cocoa sector, has implemented several measures to help farmers achieve maximum cocoa output. However, there are still challenges in the sector. This study looked at the management practices adopted by farmers and its impact on cocoa yield in the Asutifi North District of G...

Spatio-Temporal Information And Analysis Of Land Use/Land Cover Changes In The Muni-Pomadze Wetland

ABSTRACT Land use/land cover dynamics in wetland catchments is poorly understood; even though it is an important indicator of wetland ecological health. The study was aimed at detecting and quantifying Land Use/Land Cover (LULC) changes at the Muni-Pomadze Ramsar site in Ghana. The objective was to produce LULC maps for the area, assess the LULC dynamics during a ten year period, and establish statistical relationship between the major LULC changes and biophysical factors that influence human...

Karyotypes Of Some African COREOIDS And THE HIGHER SYSTEMATICS OF Coreoidea (Hemhiptera: Heteroptera)

ABSTRACT C ytological in vestigation s were made on some African Coreiods in the South-Eastern cocoa growing areas of Ghaia. Data is presented on karyotypes of the group. The now known karyotypes of the Coreoidea has been increased from 113 to 140 species by this study. E ffo rt has been ne.de to correlate information from this study with what exists in the litera tu re on morphological and cytotaxonomic studies rela tin g to the higher systematics cf the Coreoidea. Coreidae, Alydidae and Rho...

MODELING POVERTY STATUS OF GHANAIANS: A LOGISTIC REGRESSION APPROACH

ABSTRACT The poor are not evenly distributed within the country and they do not share the same socio-economic and demographic characteristics. It is against this background that analysis of the characteristics that differentiate the poor from the non-poor in Ghana cannot be underestimated. Poverty indicators make it possible to analyze the likely determinants and are, therefore, essential for formulating policy interventions that may contribute directly or indirectly to its alleviation. This ...

Spatio-Temporal Distribution And Insecticide Resistance Status Of Aedes Mosquitoes In Ghana

ABSTRACT Background: The Aedes mosquito is an important vector of arboviruses, which include the Yellow fever virus (YFV), Dengue virus (DENV), and Chikungunya virus (CHIKV). Spatial distribution by their shared vectors is grounded on environmental and demographic factors. Currently, vector control is still the main instrument to reduce or eradicate incidence of arboviruses since there are no effective vaccines for a number of public health important arboviruses. With an upsurge in insecticid...

Modeled Risk Of Radiation Induced Cancers After Prostate Cancer Radiation Treatment

ABSTRACT This study investigates into the second cancer risks to the bladder and rectum during Three-Dimensional Conformal Radiotherapy Treatment (3D-CRT) of prostate cancer compared to the baseline cancer risks in literature. The risk of induced-radiation cancer related with radiation treatment for patients with prostate cancer is of great importance in clinical radiation oncology. Therefore, the dose response relationship to predict radiation-induced secondary cancers was modeled for locali...

Phage - Mediated Transfer Of Genetic Material

ABSTRACT Ten phages were isolated randomly from sewage sources and disposal points on the University of Ghana,Legon campus, purified and characterised as delivery systems for the resistance marker genes, Strr and Benr. The phages were found to have proteins of relative molecular weights ranging from 9,000 - 100,000. Eight phages were found to be morphologically related to the tailed phages. The other two were tailless phages. All the coliphages isolated were morphologically related to the T-e...

Recognition Of Face Images Under Varying Expressions Using Discrete Wavelet Transform And Principal Component Analysis With Singular Value Decomposition

ABSTRACT The face is the most widely used part of the human body for recognition. Automated face recognition is all about transferring an inherent trait in humans into machines by supplying the machine with enough information. Face recognition has gained much attention over the past few decades and it is used in numerous application areas which includes but not limited to information privacy, law enforcement and assess management. The study presents an assessment of the Discrete Wavelet Trans...

Patient Radiation Dose Assessment During Fluoroscopic Procedures: A Survey To Propose Local Diagnostic Reference Levels For Selected Facilities

ABSTRACT The primary aim of this work was to propose local diagnostic reference levels for fluoroscopic examinations in some selected radiological imaging facilities in Ghana. The work also aimed at investigating the distribution levels of patient radiation dose received during fluoroscopic examinations for subsequent improvement of optimization. Prior to the starting of this research a series of quality control tests were performed using the Piranha kit to assess the machine output. The pati...

Assessment Of Nutritional Quality Of Market Samples Of Fruit Drinks In Owerri

ABSTRACT Nutritional quality of market samples of some fruit drinks were assessed through laboratory analysis. The assessment covered the determination of quality parameters of six brands of fruits drinks which include California brands of orange and pineapple drinks, orange and pineapple fruta drinks and 5 – alive orange and pineapple drinks. The assessment indices included the determination of proximate compositions, mineral composition and vitamin composition of the drinks. From the re...

Statistical Modelling Of Factors Affecting Students Academic Performance In The Second Cycle Institutions. A Case Syudy Of Nsawam- Adoagyiri Municipality, Ghana.

ABSTRACT Academic performance is vital in education as it helps in the selection and placement of students from one stage to the other on academic ladder. However, academic performance of students in the second cycle institutions has continually declined over the last decade. In 2014, approximately 28 percent of the students who sat for the WASSCE had grade A1 to C6 in all the core subjects. This study identifies statistically significant factors that influence students’ academic performanc...

Assessment And Evaluation Of Factors Affecting Teledensity, Growth In Nigeria.

ABSTRACT Liberalization of Telecommunication Industry was established in 2001 by the Olusegun Obasanjo administration and since then, it is a common knowledge that Nigeria’s Tele-density have improved. However, it is the researcher’s intention to put this level of improvement in quantifiable terms vis-a-viz certain factors and distribution pattern. This study span for ten years [2001-2011] and four leading telecommunication firms were selected to represent the entire Telecommunication In...

Comparative Analysis Of Statistical Models In Credit Assessment

ABSTRACT With the emergence of the current financial crisis, important advances have been made in credit risk management. Inherent in this management process is the assessment of creditworthiness routine which subsequently leads to a credit granting decision. This study is aimed at developing a statistical model that can be used to ascertain credit assessment and to predict the probability of default of firms seeking credit from a Ghanaian commercial bank. Subsequently, an attempt was made to...

Investigating Titin Splicing In Mouse Muscle

ABSTRACT Titin is a giant protein that is known for its contribution to muscle elasticity and sarcomere assembly in vertebrate striated muscles. There is considerable interest in understanding the expression of the single gene (TTN) that encodes titin because mutations in the coding gene have been implicated in muscular dystrophy. Insights into the regulatory mechanisms involved in titin splicing would contribute to the development of effective treatments for titin associated muscular dystrop...
