Evaluation of Corm, Pseudo stem and Pheromone Traps for The Monitoring of Cosmopolites Sordid us, German (Coleopteran: Curculionidae) In Kade, Ghana.

ABSTRACT Cosmopolites sordid us is a major pest of plantain in most plantain growing regions in the world and causing 34.8% yield loss in Ghana. Info chemicals (pheromones and kairomones) can be a potential monitoring tool for plantain weevil borer Cosmopolites sordidus Germar (Coleoptera: Curculionidae). The adult weevil produces an aggregation pheromone which attracts both males and females and the attractive compound Sordid in has been identified and synthesised for commercial purpose. The...

Hydro geochemical Characterization of the Rocks of the Accra Plains for a Radioactive Waste Repository

Abstract The geological disposal of radioactive waste in well-engineered repositories in stable geological formations has been internationally accepted as a suitable option. The disposal system makes use of both man-made and natural barriers to contain and isolation the radionuclides. Precambrian crystalline rocks are regarded as one of the favorable host rocks for a radioactive waste repository. Hydro geochemical characterization of the rocks of the Accra Plains, located in the south easter...

Evaluation of Safety Parameters for Gharr-1 After Nineteen (19) Years of Operation

ABSTRACT Evaluation of safety parameters of GHARR-1 after nineteen years of operation was performed and are presented herein. This work serves as an input into periodic evaluations of safety parameters. Due to fuel depletion, the excess reactivity for GHARR1 drops to the allowed lower limit of 2.3 mk from 4 mk in about 2 years. Beryllium is added to the top shim tray of the core to compensate for reactivity loss. The addition of beryllium to the top of the core requires evaluations of safety ...

Comparative Study of Energy Dispersive X-ray Spectrum Deconvolution: PyMCA and WinAxil

ABSTRACT A comparative study of spectrum deconvolution and quantitative analysis between PyMCA & WinAxil has been undertaken. Standard spectra of X-ray Kα lines (Ti, Fe, Co, Ni, Cu, Zn, As, Sr & Y) & Lα lines (Ce, Sm, Dy, Ta, W, Hg & U) were fitted with both software; also spectra of three soil samples were fitted with both software. Intensities of the elements of the standard spectra were obtained from the results of the fitting using both software and comparisons were made separately for ...

An Investigation into Impact of Unsprayed Surfaces On Mosquito Behaviour and Malaria Transmission in an Area Undergoing Indoor Residual Spraying in Northern Ghana

ABSTRACT Indoor Residual Spraying (IRS) is one of the malaria vector control tools used in the control of malaria and has helped to reduce malaria transmission in many areas in SubSaharan Africa. This involves spraying the walls of rooms with insecticides so as to kill any mosquito that rest on the insecticide treated walls after feeding. However, recent discussions have been centered on the role unsprayed surfaces such as hanging cloths play in sprayed rooms in malaria transmission. In ...

CHAPTER ONE 1.0 GENERAL INTRODUCTION 1.1 Introduction Grains constitute the most important staple food for the growing population in most parts of the world and are usually stored to provide food reserve and seeds for planting (Niber, 1994). Maize is a very important crop of the world after wheat and rice (Purseglove, 1992). Maize (Zea mays) originated in America, and is now the principal cereal crop in the tropics and sub-tropics (FAO, 1992). In Ghana, maize is the largest staple crop ...

Assessing The Vulnerability of Coastal Communities to The Impacts of Climate Change: A Case Study of the Anloga Community

ABSTRACT In recent years, global warming/climate change has caused many glaciers to melt with the subsequent rising of sea levels. This has put many coastal communities all over the world especially those in developing countries at risk. The vulnerability of these communities to the impacts of climate change depends on many factors including environmental and socio-economic factors. This study sought to assess the vulnerability of coastal communities in Ghana to the impacts of climate ch...

Assessment of Levels of Occupational Exposure to Extremely Low Frequency Electric and Magnetic Fields in Data Centres in Greater Accra Region-Ghana.

ABSTRACT Data centres use a lot of power, consumed by two main usages: power required to run the actual equipment and power required to cool the equipment. Usage of electricity results in the production of electric and magnetic fields (EMF). Even though electricity is useful in human lives, there have been reported cases of adverse health effects from EMF generated from its use. Because the use of electricity is ubiquitous and plays a vital role in society’s economy, the possibility of harm...
