Natural Radioactivity Levels In Rocks And Sand From Tyaa River In Mwingi, Kitui County

ABSTRACT The variability of background radiation from primordial radionuclides has led to the exposure of human beings to radiation doses of different ranges. Prompt or delayed harmful effects as a result of radiation exposure have been reported in areas with enhanced levels of radioactivity. The residents of Kitui County near Tyaa River and the surrounding regions heavily mine sand and rocks from its riverine for construction purposes despite the scanty information on the potential harm in c...

Effectiveness Of Teaching Þÿ P R E P A R A T I O N S O N S T U D E N T S Achievement, Attitude, Motivation And Classroom Interactions In Mathematics In Public Secondary Schools, Makueni Distr

ABSTRACT As more and more Kenyans attach great value to education, there is need to look at use of instructional products on academic performance of students. Enough evidence abounds to show that students have problems in understanding concepts and skills, which are not systematically presented in mathematics. This study was designed to investigate the instructional potential of instructional plans in the teaching and learning of vectors in mathematics. The study adopted the Solomon Four-grou...

Influence Of Human Resource Management Practices On Growth Of Sacco Societies In South Rift Region

ABSTRACT Human Resource Management (HRM) practices will continually attract the attention of researchers in pursuit of better ways to counter the emerging challenges that can undermine the growth of the organizations. The research will be carried out to examine the influence of human resource management practices on the growth of Savings and Credit cooperative societies (Sacco societies) in South Rift Region. The study will examine the relationship among the factor variables which are; select...

Application Of Markov Chain Model In Transition Of Girls In Public Secondary Schools; A Case Study Of Kisumu West Sub-County, Kenya

ABSTRACT Transition is a very important factor in determining success of a student in secondary school. It forms a basis for implementing poverty reduction strategy by the government through acquisition of basic literal skills to increase opportunities for employment. Girls have not had an efficient transition from form one to the next form in secondary schools because of choices of secondary school types they enroll in. This research uses a Markov chain model to compare and predict the perce...

Selected Physiological And Growth Response Of Four Soy Beanvarieties To Aluminium Chloride Stress

ABSTRACT Soy bean v arieties commonly gro wn in Kenya`s acidic soils that contain aluminium are SB 97, SB 19, SB 20 and SB 123. Soy bean grains have high protein content, vitamins and used to manufacture industrial products. Aluminium toxicity affect growth and physiology of plant growth . The effects of aluminium chloride solution on plant growth, uptake of mineral nutrients and di stribution in vegetative parts of soy beans are still not fully understood. The objective of this study was to ...

Research and Development of a mobile voice over IP application which is hosted by open source software running on inexpensive backend servers

ABSTRACT Voice over IP has been driven by the convergence of voice and data on a single transport medium. This means cheaper service usage fees for the user if the offering is costed properly. But for a service provider there is still an increase in expenditure, solely related to spending on infrastructure such as call servers, phones and gateways. This study is aimed at analysing a different strategy of deploying VoIP, by starting at a lower base, meaning hosting the VoIP application on ine...

Application Of Markov Chain Model In Career Progression Of University Academic Staff:A Case Study Of The Moi University - Eldoret, Kenya.

ABSTRACT The use of Mathematical models for manpower planning has increased in recent times for better manpower planning quantitatively both in public and private sectors. In respect of organizational management, numerous previous studies have applied Markov chain models in describing title or level promotions, demotions, recruitment, withdrawals, or changes of different career development paths to confirm the actual manpower needs of an organization or predict the future manpower needs. The ...

Effect Of Concentration Of Reactants And Deposition Temperature On The Optical Properties Of Iron-Doped Cadmium Stannate Thin Films Deposited On Glass Substrates By Spray Pyrolysis

ABSTRACT Thin films (TFs) have numerous applications in the modern technological world, ranging from energy production in TF solar cells/ photovoltaic (PV) cells to liquid crystal displays (LCDs) in television screens and in smartphone touch screens as transparent conducting oxides (TCOs). The most commonly used TCO material is indium tin oxide (ITO). However, ITO has two main drawbacks. Firstly, indium is expensive and secondly, it is rare. These drawbacks call for relatively cheaper compoun...

Evaluation Of Point-Of-Care Test For Early Infant Diagnosis And Viral Load Monitoring Of Hiv-1 Infection In Western Kenya

ABSTRACT In developing countries with disproportionately high burden of HIV-1 (HIV) infections, access to early infant diagnosis (EID) and viral load (VL) HIV nucleic acid testing is limited by the prohibitive infrastructural costs of centralized testing laboratories. To increase access to HIVEID and VL monitoring, development of robust and low cost point of care (POC) technologies is a priority of current HIV diagnostic research. In Kenya, a number of POC technologies are being evaluated for...

A Delayed Vaccination Model For Rotavirus.

ABSTRACT Rotavirus is the most common cause of severe gastroenteritis infection in infants and young children, occurring even with very high standard of hygiene. The disease spreads by contact with infected faeces and might also be transmitted through faecally-contaminated: food, water and respiratory droplets. Rota teq and Rotarix are the two licensed oral vaccine intervention for rotavirus. However, it takes time for the development of vaccineinduced immunity to complete, hence the need to ...

The Influence Of Blood Meal On Susceptibility To Pyrethroids In Anopheles Gambiae From Bungoma, Western Kenya

ABSTRACT Malaria continues to be an important disease in the tropics posing a major obstacle to sustainable development. Malaria control is dependent on pyrethroid insecticides yet resistance to these insecticides in the malaria vector Anopheles gambiae is receiving increasing attention because it threatens the sustainability of malaria vector control programs targeted at indoor resting mosquitoes in Western Kenya. Common mechanism of resistance reported to these insecticides is target site i...

Mathematical Modelling Of Hiv/Aids Co-Infection With Tuberculosis And Pneumonia Incorporating Protection

ABSTRACT The synergistic relationship between HIV/AIDS and respiratory infections, such as tu- berculosis(TB) and pneumonia not only results in high mortality rates but is also a source of economic burden borne by many nations in the sub-saharan Africa. The search for a cure or vaccine for HIV/AIDS has yielded no conclusive results so far. Treatment fail- ure and lack of adherence to treatment schedule which results in the evolution of drug resistant strains of diseases are challenges to grap...

An assessment of the environmental impacts associated with urban agriculture. A case of gweru, zimbabwe

Abstract The study assessed the environmental impacts associated with urban agriculture in selected residential areas of Gweru Urban. Qualitative research methods were prominently utilised throughout the research and were complimented by quantitative methods. Questionnaires, structured interviews and direct observations were used in soliciting significant information relevant to the study objectives. Self-administration of questionnaires was done to 35 household units which were selected thr...

Taxonomic Studies Of Lippia Javanica (Burm F.) Spreng. (Verbenaceae) Complex In East Africa Using Morphological And Molecular Characters And Evaluation Of Its Pesticidal Efficacy On Aphids

Abstract Lippia javanica (Burm. F.) Spreng occurs naturally in eastern, central and southern Africa. It has widely been used as herbal tea, for ethnomedicinal applications and as a botanical pesticide. Lippia javanica species exhibit great morphological and chemical variations which are notable across a number of natural populations. Differences in morphological taxonomy on important characters such as peduncle length and number of inflorescence per axil have been reported which has led to th...
