Hydrogeological Characteristics Of Aquifers In The Greater Accra Region

The economic importance of groundwater in the Greater Accra Region cannot be overemphasized, since supply from boreholes and wells continues to be the most dependable alternative sources of water for most rural and urban communities in the region. Three different consolidated hard rocks underlie the region making it difficult to produce volumes of groundwater for supplies. Demand for portable water has led to the drilling of large numbers of boreholes. This study stat...

Evaluation Of The Potential Of Adding Tiger Nut Milk And Soy Milk Into Cheese Making

ABSTRACT The purpose of this study was to evaluate the potential of incorporating tiger nut milk and soy milk in cheese making. In all 16 different formulations were prepared from tiger nut milk, soy milk and cow milk. Texture analysis, colour evaluation and chemical analysis were carried out on all the 16 cheese samples. Two parameters were measured (firmness and fracturability). Protein, fat, moisture content and pH were determined with respect to the chemical analysis. For the c...

Studies On Damage By Prostephanus Tr Unca Tus(Jhorn) (Coleoptera: Bostrichidae) And Araecerus Fascicula Tus Pe G E E R ) (Coleoptera: Anthribidae) To Dried Yam Chips

In West Africa, especially Nigeria, Benin Republic, Togo and Ghana, dried yam chips constitute an important food material. The recent introduction of the larger grain borer into Africa and its devastating effect on cassava chips necessitated a study of the biology and damage caused by Prostephanus truncatus (Horn) (Coleoptera: Bostrichidea) and Araecerus fasciculatus (Degeer) (Coleoptera: Anthribidea) on dried yam chips in Ghana. Three yam varieties were investigated ...

Profiling of Some Amoxicillin Drugs in Ghana Using Nuclear Magnetic Resonance Spectroscopy

The prevalence of counterfeit drugs is seen as a problem faced in both developed and developing countries where Ghana is not an exception. Antibiotics are amongst the most counterfeit drugs in developing countries. What is less understood is that there are inadequate and ineffective quality control procedures in monitoring of drugs manufactured and imported into the country. This research work is aimed at contributing towards the development of routine analytical proc...

Understanding the Kerala Floods of 2018: Role of Mixed Rossby-Gravity Waves

Kerala, the south-west coastal state of India, was ravaged by a series of floods during the South-West Monsoon of 2018, as a consequence of severely anomalous rainfall trends. Although, there were many studies about the hydrogeological factors which aggravated the floods in Kerala, no attempt was made to delve into the physics which actually resulted in anomalous precipitation during the year. This study intends to document the dynamical phenomenon which caused the Kerala Floods of 2018. The ...

Role Of Government And Community In Landslide Risk And Vulnerability Reduction: A Case Study Of Gakenke District, Rwanda

ABSTRACTThe frequency and the severity of landslides have increased in recent times globally, with serious implications for human lives and property, as well as national economies. In many disaster response initiatives, community-based disaster management approach is adopted as a quick solution to emergency response. This study was carried out in Gakenke District in the Northern Province of Rwanda, which is highly prone to landslide disasters. It investigated the role of government and local ...

Africa Within Global Smart Cities: What Do We Know And How To Proceed?

Abstract Increasing globalization, unprecedented urbanisation, environmental consciousness and technology development has redirected global cities' focus towards strategic and smart solutions to solve issues changing city dynamics through a smart city agenda, African cities included. The smart city agenda has been globally debated via varying perspectives but most of the concept's ideology has been limited to the diffusion of technology; excluding social, human, economic, environmental c...

Mainstreaming Climate Change Adaptation Into National Development Process: The Role Of The Legislature.

ABSTRACTClimate change mainstreaming undoubtedly remains the most cost effective and surest way of adapting and building resilience to climate change. Knowledge of Parliamentarians as a stakeholder and one of the highest initiators of laws and policies on climate change cannot be ignored in the climate change discourse. Inadequate knowledge and information among parliamentarians on climate change mainstreaming has a negative influence on political will and support for climate change activitie...

A Search For Indigenous Parasitoids For The Control Of The Larger Grain Borer, Prostephanus Truncatus (Horn) (Coleoptera: Bostrichidae)

ABSTRACTThis study was conducted to identify indigenous parasitoids for the control of the larger grainborer, Prostephanus truncatus (Horn) (Coleoptera : Bostrichidae). A search was conducted atvarious market stores in the Greater Accra and Volta Regions to collect and identify parasitoidsassociated with stored product pests. Anisopteromalus calandrae (Howard)(Hymenoptera : Pteromalidae) and Dinarmus basalis (Rondani) (Hymenoptera : Pteromalidae)associated respectively with Sitophilus zeamais...

Climate Variability And Cocoa Production: The Implications Of Micro-Adaptation Measures On Cocoa Farmers’ Income

ABSTRACT Climate change is having severe impacts on agricultural production and food security, with yields from rain-fed agriculture in developing countries projected to halve by 2020. One crop vulnerable to the effect of climate variability and change is cocoa (Theobroma cacao). Though there are extensive studies on how the cocoa sector can adapt to the adverse effects of climate variability and change, little empirical research has been carried out on the consequences of micro-ada...

Lived Experiences Of Female Basic School Dropouts: A Social Capital Perspective

ABSTRACT The undesirable impact of female school dropout has attracted attention from governments, stakeholders, national as well as multinational institutions to look at the phenomenon from various perspectives. This study was conducted to gain insight into the causes of basic school dropout behaviour among females in the Narhman community, Accra, within a social capital framework. A cross sectional design with a qualitative approach was used to interview eighteen respondents usin...

Study of Heat Transfer in Circular Tubes with Supercritical Fluid by the STAR-CCM+ CFD Code

ABSTRACTSupercritical Cooled-Water Reactor (SCWR) which is planned to be deployed by 2030derives its concept from Light Water Reactors (Boiling Water Reactor (BWR), PressurizedWater Reactor (PWR) and Fossil Fired Coal Plant but with a simpler design. Due to thestrong variations of density at supercritical pressure, the SCWR is likely to inherit some ofthe issues related to the LWR’s in terms of heat transfer (e.g. thermal crisis). This researchwas undertaken in order to better understand th...

Finite Element Assessment of Precast Concrete Slab Using Ansys Structural

ABSTRACT Concrete is used widely in all types of construction. In particular, it is the first choice material for the construction of various industries, due to its affordability, durability, heat resistance, strength, etc. Based on this, understanding the response of concrete structural components for all types of loading is crucial to the development of an overall safe and efficient structure. Various methods have been used to study the response of concrete structural components to v...

Comparative Evaluation Of Sandstones Properties In Parts Of The Anambra Basin, Southeastern Nigeria

ABSTRACT The evaluation of sandstone properties in parts of the Anambra Basin was undertaken to identify the spatial distribution of textural, petrophysical and mineralogical properties of sandstone bodies in the area in order to assess their potentials to host hydrocarbons. Sandstone units from Nkporo Formation, Mamu Formation, Ajali Sandstone and Umuna Sandstone were subjected to textural analysis using sediment granulometry, thin-section petrography and geochemical analysis. Following...

Control Of Prostephanus Trunca Tvs (Horn) (Coleoptera: Bostrichidae) Through The Treatment Of Wood Used For The Construction Of Maize Storage Barns

ABSTRACT The ability of the Larger Grain Borer (LGB), Prostephanus truncatus (Horn ). to bore and survive for several weeks in various wood materials led many pest control specialists to conclude that the quick and early build up of the pest in stores results from residual populations from previous infestation that survived in the wooden store structure. The relative susceptibility to P. truncatus infestation of five wood species: stems of borassus/fan palm (Borassus aethiopium (War...
