Statistical Thermodynamics Of High Tctwo Band Superconductivity In Mgb2.

ABSTRACTThermodynamic properties of the multiband high critical temperature superconductors havebeen describedpreviously with simple standard BCS expressions corresponding to and  bands,but the microscopic mechanisms that allow superconductivity to persist at high temperaturesremain unknown. Studies on two band superconductors have previously been described throughone band model; this approach has not adequately addressed cases of inter-band scattering forsuperconductors at high temperature...

Internet of Things Based Greenhouse

ABSTRACT The purpose of this study was to develop a system that can help farmers and garden enthusiasts to manage their greenhouses by the use of a network of sensors connected together and controlled by a central hub. This complies with the world vision of connecting as much devices together as possible that has been dubbed the Internet of Things phenomenon. The system makes use of sensors that a controlled by a central controller that sends the data to a server that streams the data t...

The system targets higher learning institutions, i.e universities and colleges.I have implemented the following modules/sub-systems: student portal, finance system, library system, i-voting system and m-voting system, HR system, employee porta...

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

ABSTRACTThe 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 ca...

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

ABSTRACTAs more and more Kenyans attach great value to education, there is need to look at useof instructional products on academic performance of students. Enough evidenceabounds to show that students have problems in understanding concepts and skills,which are not systematically presented in mathematics. This study was designed toinvestigate the instructional potential of instructional plans in the teaching and learningof vectors in mathematics.The study adopted the Solomon Four-group quasi...

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

ABSTRACTHuman 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; selecti...

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

ABSTRACTTransition is a very important factor in determining success of a student in secondaryschool. It forms a basis for implementing poverty reduction strategy by the governmentthrough acquisition of basic literal skills to increase opportunities for employment. Girlshave not had an efficient transition from form one to the next form in secondary schoolsbecause of choices of secondary school types they enroll in. This research uses a Markovchain model to compare and predict the percentage ...

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

ABSTRACTSoy beanv 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 tomanufacture industrial products. Aluminium toxicity affect growth and physiology of plantgrowth . The effects of aluminium chloride solution on plant growth, uptake of mineral nutrientsand di stribution in vegetative parts of soy beans are still not fully understood. The objective ofthis study was to investi...

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...

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

ABSTRACTThe use of Mathematical models for manpower planning has increased in recent times forbetter manpower planning quantitatively both in public and private sectors. In respectof organizational management, numerous previous studies have applied Markov chainmodels in describing title or level promotions, demotions, recruitment, withdrawals, orchanges of different career development paths to confirm the actual manpower needs ofan organization or predict the future manpower needs. The moveme...

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

ABSTRACTThin 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 compound...

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

ABSTRACTIn 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.

ABSTRACTRotavirus is the most common cause of severe gastroenteritis infection in infants andyoung children, occurring even with very high standard of hygiene. The disease spreads bycontact with infected faeces and might also be transmitted through faecally-contaminated:food, water and respiratory droplets. Rota teq and Rotarix are the two licensed oralvaccine intervention for rotavirus. However, it takes time for the development of vaccineinducedimmunity to complete, hence the need to invest...

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

ABSTRACTMalaria 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 in...

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

ABSTRACTThe 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 sourceof economic burden borne by many nations in the sub-saharan Africa. The search for acure 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 drugresistant strains of diseases are challenges to grapple wi...
