Determination Of Levels Of Some Vitamins In Amaranthus Hypochondriacus And Amaranthus Cruenthus Leaves And Grains From Selected Areas Of Kenya

Vitamin deficiencies are health hazards in some parts of Kenya. These are attributed to inadequate access to vitamin-rich foods occasioned by decline in agricultural production due to unfavourable climatic conditions, low purchasing power due to poverty, over reliance on staple foods and dependence on highly refined foods, which are poor in vitamins. Higher intake of vitamin-rich vegetables and grains can alleviate this problem. Grain amaranth (GA), which is relatively a new crop in Ken...

Farmers’ Perceptions And Adoption Of Micro Catchments For Improved Establishment Of Agroforestry Trees In East Shewa Zone, Ethiopia

ABSTRACTTree planting on farms has both environmental and socioeconomic benefits. The practice of establishing trees and tree plantations is common among rural population in the dry regions of Ethiopia, who depend on livestock, trees and tree products for subsistence. Despite the importance of trees, their survival in these dry areas is low and often challenged by drought and water shortage. To address the water scarcity problem, two micro catchments specifically, micro basins and trenches we...

Sulphate And Chloride Ingress And The Effect In Selected Cements Mortar Prisms Immersed In Sea Water And Leather Industry Effluent

ABSTRACTThe effect of ingress of Cl- and SO42- on compressive strength development and the ionsdiffusivity in selected Ordinary Portland Cement (OPC) was investigated. The aggressivemedia used included sea water (SW) and waste water from leather industry (WLI). Threebrands of commonly used cements of OPC in Kenya were used. Mortar prisms wereprepared for each brand of cement at different water to cement ratio; (w/c) of 0.5, 0.6, 0.65and 0.7 and allowed to cure for 28 days in a highly ...

Study Of Bioavailability Of Trace Elements In Selected Indigenous Foods And Their Potential Use On Management Of Hiv And Aids

ABSTRACTHIV infection increases nutritional demands and vulnerability to malnutrition. Malnutrition worsens the effects of HIV infection by weakening further the body’s immune system, resulting in earlier and faster progression to the end stage of AIDS. Food supplementation especially with essential elements improves nutritional and clinical status of PLWHA and may delay early use of ARVs. Although high levels of essential elements have been recorded in some indigenous foods, translating ph...

Assessment Of Kangemi Sewage Treatment Works Efficiency And The Impact Of The Effluent On Water Quality Of Chania River Nyeri, Kenya

ABSTRACTSewage treatment plants (WTPs) use a combination of physical, chemical and biological processes to reduce the pollutant loads in wastewater. The treated wastewater is then either discharged to surface water or is reused. Successive stages in wastewater treatment plants reduce the quantity of suspended solids, biological contaminants, organic matter content and nutrient constituents in sewage. Changes in the properties of the effluents can occur along the treatment process leading to r...

Genotyping Sorghum Germplasm In Tanzania Using Microsatellite Markers

ABS TRACTMicrosatellite markers are increasingly being used in crop plants to discriminateamong genotypes and as tools in marker-assisted selection. In this study microsatellitemarkers were used to quantify the genetic diversity within as well as among 200accessions sampled from sorghum germplasm collection at Tanzania National genebank germplasm collection of sorghum. Although all methods did not provide similardescription of relationships between accessions, there existed some consistency i...

Establishment Of Woody Savannah Species On Various Mined Substrates: Toward Rehabilitating Self Sustaining Plant Communities At Navachab Gold Mine

ABSTRACTFor many years mining has been a vital component of the development of many countries. Although an important income generator, mining is one of the factors that affect biodiversity and ecosystems.There is an increase in the intensity of environmental damage caused by mining over the years, and thus an increased need to rehabilitate the disturbed ecosystems. The success of any rehabilitation project requires an ecological understanding of natural indigenous vegetation communities. This...

Assessment Of Mistletoe - Host Interactions In A Highland Savanna In Windhoek, Namibia

ABSTRACTMistletoes have detrimental effects in ecosystems where they occur. Mistletoes negatively reduce the growth of the host plants and increase the chance of tree mortality. Apart from tree mortality, infected trees suffer from reduced growth and loss of vigor hence contributing to overall low productivity of hosts and resulting in changes in the structure and function of savanna communities. This study’s aim was to determine and to compare mistletoe - host interactions between the Bota...

Central Bus Terminal Port Harcourt Easy Circulation Flow

ABSTRACT The importance of the public transit system has been growing increasingly in order to achieve smooth traffic in urban areas. One of the most used transit systems is the bus transit system. In this study, the author aims to follow two points focusing on the role of the bus transit system as public transportation. The first point is to review how to treat and to clarify the significance of the bus transit system with exclusive bus-ways in public transportation planning. The ...

Agoa And African Underdevelopment, A Critical Analysis of A Major Contradictions

ABSTRACT The study examines the African Growth and Opportunity Act and African underdevelopment, a critical analysis of major contradictions. The thrust of the research work is to find out if AGOA has spurred the level of investment needed to expand economic activity in the rural agricultural sector. The research work also seeks to examine if AGOA has promoted export diversification with particular reference to the clothing and textile industry and the degree the US trade with SSA count...

Detection Of Viruses And The Spatial And Temporal Spread Patterns Of Viral Diseases Of Cucurbits (Cucurbitaceae Spp.) In The Coastal Savannah Zone Of Ghana

ABSTRACTCucurbits are susceptible to over 35 plant viruses; each of these viruses is capable of causing total crop failure in a poorly managed virus pathosystem. The objectives of this study were to detect the viruses that infect six cucurbit species in the coastal savannah zone of Ghana and to describe the spatial and temporal spread patterns of virus epidemics in zucchini squash (Cucurbita pepo L.) by the use of mathematical and geostatistical models. Cucumber (Cucumis sativus L.), watermel...

Comparative Cost - Benefit Analysis Of Fresh And Seed Okro Production At Kpando In The Volta Region

ABSTRA CT Okro is an important crop in the diet o f many Ghanaians and the economy o f Ghana. Fresh okro contains some amount o f protein, carbohydrates, vitamins A and C w ith traces o f B vitamins, as well as calcium phosphorus and iron. The problems o f removal o f subsidies on agricultural inputs, poor market price o f fresh okro, and nematode problem had resulted in low net income from fresh okro enterprise. Although Ghana has a high potential o f producing both fresh and seed okro...

Phosphorus Adsorption Maxima Of Selected Ghanaian Soils And Their Relationship To Phosphorus Availability

INTRODUCTION An adequate knowledge of the chemical reactions which occur when fertilizer is placed in soils is a pre-requisite to the development of sound fertilizer practices. Without such a knowledge, there is the possibility of applying either too much or too little fertilizer than is necessary with its consequent crop failure. Phosphorus is one of the major nutrient elements required by plants for growth. The role of phosphorus in plant nutrition includes its effect on cell divis...

Climate Shocks, Environmental Degradation And Resource Conflict: Implications For Agricultural Livelihoods And Food Security In Niger Delta Region Of Nigeria

ABSTRACT There is an overwhelming evidence to suggest that environmental change drives conflicts, and that resource depletion and degradation undermine food security and livelihood wellbeing in communities where people are dependent on land and water resources. Therefore, understanding the vulnerability, food security, adaptation and resilience aspects of climate shocks in the context of land degradation and conflicts has immense practical significance particularly in the climateimpacted...
