ABSTRACT The sun provides an abundant and clean source of energy. However the supply of this energy is periodic following yearly and diurnal cycles, intermittent, unpredictable and it is diffused. Its density is low compared to the energy flux densities found in convectional fossil energy sources like coal or oil. There have been attempts to produce solar thermal power using parabolic trough technology as was demonstrated by Luz Company which built a solar electricity generating station with ...
ABSTRACT In Kenya, most water utilities have been publicly owned and managed. These utility firms have thus been getting financial support from the government in form of subsidies in addition to the revenue they generate internally. However there has been low level of investment in peri-urban areas by both public and private players creating an investment opportunity. Nevertheless this opportunity is not taken up by small scale water investors hence water scarcity. Many people in these areas ...
Abstract A qualitative study, framed within a hermeneutic phenomenological stance, was undertaken to explore and describe the essence of the meaning of help in mathematics from the perspective of high school students. Participants were drawn from seven high schools located in the eastern and mid-eastern regions of Tanzania Mainland. The participants were asked to recall and describe a moment when they either sought or gave help in mathematics. Data were gathered through in-depth interviews an...
ABSTRACT Continued food insecurity is a major global concern especially in Africa and Kenya in particular. The threats of the desert locust and the novel Corona Virus (Covid-19) pandemic have further accelerated this challenge. Despite her vast productive land, Kenya has been importing staple food particularly maize while her citizens have been pleading with the government to provide food especially maize flour. The youth on the other hand, cannot adequately employ the agricultural skills dev...
ABSTRACT Antisocial behaviour is a major challenge in secondary schools in Kenya. It is linked with delinquent behaviour such as truancy, drug abuse and bullying. These behaviours are related to negative interactions with parents, teachers and peers. The individual lives in constant conflict which results in ultimate long time consequences like failing examinations, frustrations and failure in life. The aim of this study was to investigate the contributions of microsystems to antisocial behav...
ABSTRACT The objective of this study is to expound and amplify the thesis that "Even Nothing is something". The thesis itself is one of the far-reaching consequences of Heidegger's phenomenological ontology. Ontology, for Heidegger, is the science of the Being of entities. The task proper to ontology is the exhibition of the general structures of the world. Phenomenology is the method of exhibiting entities as they are without preconceptions. The outstanding phenomenon of phenomenological tho...
ABSTRACT The study assessed the role performance of local government councils in agricultural development in south-east Nigeria. Specifically, the study was designed to: ascertain role expectations of LGCs agriculture departments as perceived by LG agriculture/veterinary department staff and farmers, determine agricultural role achievements of LGCs as perceived by LG staff and farmers, ascertain LGs’ funding for agriculture from 2007 to 2011, identify linkages that exist between farmers, LG...
ABSTRACT Robert Nozick’s Entitlement Theory consists of three principles of justice in Acquisition, in Transfer and in Rectification. The entitlement theory of Nozick entails that a person is entitled to a holding if he followed the principle of acquisition, transfer and rectification. Raising the issue of equitable distribution and individual appropriation, Nozick’s entitlement theory of individual right and private property right defends free market and absolute private property right. ...
ABSTRACT Contemporary societies have become bedevilled by environmental problems like drastic climatic change, health problems, and the loss of land, habitats, and wildlife. In most places these problems are a direct consequence of man‘s exploitation of nature. Since it is arguable that attitudes influence action, the hitherto unquestioning dependence on anthropocentrism as a guide to the man–nature relationship may be blamed for these environmental crises. The realization that there was ...
ABSTRACT Ayn Rand advanced and propagated the view that rational selfishness should be pursued at all cost instead of altruism, that the individual should be allowed by all to live as he or she pleases. The only duty of government, according to her, is to make sure that nobody takes away the freedom of the individual. This research work is aimed at evaluating this moral theory of Rand called objectivist ethics, to determine it’s strength and weakness and implications on man and society espe...
ABSTRACT The work centres on the study of Mikhail Bakunin’s concept of Power and Authority. Power and Authority are so central in the organisation of any society. No society can thrive in a situation where nobody is in control. Philosophers all through the ages have advocated for one form of power and Authority or another. In this work, Mikhail Bakunin presents his own concept of power and authority that will enable the society to attain the end or purpose of its existence. Bakunin is seen ...
ABSTRACT The gold standard for pulmonary tuberculosis (PTB) diagnosis is either isolation of Mycobacterium tuberculosis (Mtb) by culture or detection of Mtb-specific nucleic acids by molecular methods. However, apart from laboratory infrastructure, culture take longer time to get results, while molecular methods are expensive and require a lot of human expertise. Despite its limitation of lower specificity and sensitivity, Acid Fast Bacilli (AFB) microscopy smear remains the most widely used ...
ABSTRACT Tea (Camellia sinensis) is a major cash crop in Kenya that suffers economic losses due to Brevipalpus phoenicis and Oligonychus coffeae infestations during droughts. Pesticides use on tea is prohibited and pests control is through cultural and agronomic practices. Resistance/susceptibility of imported and new cultivars to mites is unknown. Plants release overhead volatile organic compounds (OVOCs) that attract or repel insect pests. Some tea cultivars are preferred while others are r...
ABSTRACT This is a study of the syntax and morphology of argument licensing in Lutsotso, a dialect of Luluhyia language. Luluhyia is an agglutinating language and therefore its morphology is relevant to syntactic derivation. Morphological processes determine the number of arguments of the verb while syntax determines the distribution of the arguments in the sentence. As such, there is interplay between morphology and syntax. Lutsotso verbs have derivational morphemes that cause valence change...
ABSTRACT Stuttering is a speech disorder characterized by repetitions, prolongations, interjections, hesitations and blocks. The prevalence rate of persons who stutter (PWS) in the World is 1%. Kenya with an estimated 440,000 PWS, of which 16,606 live in Kakamega County. Results from a baseline survey carried in Western Kenya counties between 2010 and 2013 found that Kakamega had 138 Learners Who Stutter (LWS), Vihiga 84, Bungoma 33, and Busia 10. In Kakamega, learners were enrolled in 20 sch...
