This research is of importance in the field of medicine. There is an application in magnetic hyperthermia which is used to shrink tumors in the treatment of cancer. In addition to this, the externally applied magnetic field is also used to reduce/diminish blood flow in the region of stenosis and hence it is used in the treatment of hy...

Food Consumption Patterns, Nutrient Intakes, Nutritional Status And School Attendance Among Children From Hiv/Aids Affected Households In Kiambu Municipality

ABSTRACT HIV/AIDS has orphaned millions of children worldwide and left many more with ill parents. Sub Saharan Africa is the worst hit. Kenya has an estimated one million orphaned and vulnerable children due to HIV/AIDS. Apart from illness and death of parents, children may be more vulnerable to poverty, face increased risk of malnutrition and miss out on education. The objective of this study was to assess food consumption patterns, nutrient intakes, nutritional status and school attendance...

An Analysis Of The Determinants Of Fertility In Matuga Division, Matuga Sub-County, Kwale County, Kenya

ABSTRACT The world total fertility rate has dropped from 4.95 births per woman to 2.36 births per woman in the last 50 years. In developing countries the total fertility rate has dropped from 6.0 births per woman in the 1960s to 2.9 births per woman in 2005 and was expected to have dropped even further in 2015. Kenya‟s fertility has declined from 7.8 births per woman in 1979 to 4.6 births per woman in 2009 (KNBS, 2010). Despite the general drop in fertility, there are differentials where s...

Thermo – Chemical Characteristics Of Potential Gasifier Fuels In Selected Regions Of The Lake Victoria Basin

ABSTRACT Gasification technology has failed to take off in a number of developing countries including East Africa despitebeing the most efficient way of converting biomass into energy. All countries in the Lake Victoria Basin (LVB) depend mostly on hydroelectric power for provision of modern energy. While hydropower is sensitive to climate change, gasification technology has a high potential for reducing biomass energy consumption while increasing access to electricity and clean cooking faci...

Simulation Of Cosmic Ray Muon Charge Ratio At Energies Up To 10 TeV Using Epos LHC

ABSTRACT Cosmic ray muons are produced by the interaction of primary particles with nuclei in the upper parts of the atmosphere. The charge ratio of cosmic ray muons is the ratio of the number of positive muons to negative muons. It gives valuable information on the hadronic interaction processes in the atmosphere such as the mass of the primary particle. The value of the cosmic ray muon charge ratio has been measured by several experiments to be 12766±0.0032 (the CMS detector), 1.374 ± 0....

Combining Ability Of Inbred Lines Of Maize (Zea Mays L.) And Stability Of Respective Single Crosses In Kiambu And Embu Counties Of Kenya.

ABSTRACT Despite the fact that virtually all households in Kenya grow maize over 60% of them are net maize buyers because they do not produce enough for their consumption. Kenya‘s current food supply situation and outlook give cause for serious concern. Maize is the main staple food averaging over 80% of total cereals (rice, wheat, millet and sorghum) in Kenya. Maize stocks are estimated to be depleted at all levels throughout the country. According to strategic grain bank report on food s...
