Automated Examiner Allocation System For Kenya National Examination Council

ABSTRACT This study about examiner allocation system was conducted at Kenya Examiuation council in Nairobi. It was clearly observed that the current allocation system is time and resource consuming and also not convenient due to repetition of examiner to the same centre they were allocated last season, thus creating the need for a system that will automatically allocate examiners. An administrator receives exams from different centers and forwards them to examiners for marking and then they f...

Maternal Knowledge On Complementary Feeding Practices And Nutritional Status Of Children 6-23 Months Old, Attending Kahawa West Public Health Centre, Nairobi County

ABSTRACT  Worldwide, malnutrition is responsible directly or indirectly for deaths of children under five years. Two thirds of these deaths are associated with inappropriate feeding practices. Interventions that address child malnutrition show that appropriate complementary feeding practices can save up to 6% deaths in under-fives. Attention should therefore be given to decisions taken by the mother during complementary feeding. Thus the purpose of this study was to determine mothers‟ know...

Assessment Of Levels Of Monosodium Glutamate, Aspartame And Sodium Benzoate In Some Chili And Tomato Sauces In Nairobi County, Kenya

ABSTRACT  Food additives are substances that are added to food or animal feeds during processing or storage. They are usually added to preserve or improve the quality of the food or feed. They include antioxidants, preservatives, stabilizers, coloring and flavoring agents. Food additives that are present in sauces include monosodium glutamate (MSG), saccharin, aspartame, sorbic acid and sodium benzoate. Chili and tomato sauces are extensively used by both young and old in processed foods suc...

Removal Of Turbidity, Methylene Blue And Heavy Metals From Contaminated Water Using Pyro-Processed Coconut Shell And Fiber

ABSTRACT Water is essential for all domestic and development activities worldwide. It‟s continues contamination by heavy metals is a major concern to many developing countries, Kenya included as they are non-biodegradable and toxic. This is expected to increase in tandem with the projected population and industrial growth. Therefore, it is important to systematically minimize the percentage concentration of the heavy metal ions in waste water before use or discharge into water bodies. Meth...

Synthesis And Characterization Of Low Oxidation State Cobalt Chelates

ABSTRACT Square planar complexes of cobalt in any of its common oxidation states are rare and attempt to make them either yield tetrahedral or octahedral complexes. The aim of this study was to synthesize and characterize low oxidation state complexes of cobalt using selected chelating ligands including 8-hydroxyquinoline (oxine) and glycine. It was of interest to synthesize cobalt (I) complexes of square planar geometry as these are expected to have the same mode of action as the square pla...

Genetic Engineering Of Banana Using Nonexpressor Of Pathogenesis Related Gene For Resistance To Xanthomonas Wilt And Fusarium Wilt Diseases

ABSTRACT Banana (Musa spp.) is an important fruit and staple food crop globally. It is grown in over 140 countries on more than 11 million hectares, with current production of 145 million metric tons per annum, out of which about 30 % is produced in Africa. However, its production is limited by banana Xanthomonas wilt (BXW) disease caused by bacterium Xanthomonas campestris pathovar musacearum (Xcm) and Fusarium wilt disease (FWD) caused by Fusarium oxysporum subspecies cubense race 1 (Foc)....

Assessment Of Community Awareness, Physicochemical Parameters, Organic Contaminants And Toxic Metals Of Alcoholic Beverages In Muthithi, Murang'a County, Kenya

ABSTRACT Brewing is an ancient industry that dates back 9000 years and to date more than 100 billion liters of beer are consumed annually. In Kenya alcoholic beverages industry is more liberal with the previously referred to as ‘illicit alcoholic beverages’ being legalized in November 2010, by the passing of Alcohol Law (Mututho Law). Production and consumption of some alcoholic beverages has been on increase partly due to high cost of commercial alcoholic drinks. People have died, other...

Phytochemical and in vitro anti-microbial screening of echinops hispidus fresen. And grewia similis k. Schum.

ABSTRACT Antimicrobial resistance is reported to be on the increase due to gene mutations of the disease causing pathogens. It is believed that, new antibiotics with activities and structures different from those in current use could be found through ethnobotanical route. This requires a follow up of promising leads with attempts to isolate and identify the active principles from the medicinal plants. Two Kenyan plants Echinops hispidus Fresen. (Asteraceae) and Grewia similis K. Schum. (Tili...

Gravity Survey For Geothermal Exploration In Menengai Area, Kenya

ABSTRACT Kenya has prominent geographical features such as the Rift valley which gives rise to geothermal reservoirs which can be exploited to produce geothermal energy for power generation and heating; Lake Magadi, Suswa, Eburu, Menengai, Lake Bogoria as well as other areas are considered to have potential for power geothermal energy because of the geothermal manifestations. For above mentioned regions it is known that positive gravity anomalies within the Rift valley proper are superposed ...

Investigation Of The Pyroprocessing And The Optimum Mix Ratio Of Rice Husks, Broken Bricks And Spent Bleaching Earth To Make Pozzolanic Cement

ABSTRACT This thesis reports the results of a study aimed at optimizing pozzolanic activity of a blend of Rice Husks (RH), Spent Bleaching Earth (SBE) and Broken Bricks (BB) to form pozzolana that would have pozzolanic activity comparable to natural pozzolanas. Four ratios of RH, BB, and SBE were burnt in the Fixed Bed Kiln (FBK). The starting ratio had 20 kg of RH, 0 kg of BB and 4 kg of SBE. The amount of BB was increased by 2 kg each to a maximum of 6 kg as the mass of SBE was kept consta...

Loan Management System For The Savings And Credit Cooperative Organization Case Study: Ministry Of Finance And Economic Affairs, Dar-Es Salaam, Tanzania

ABSTRACT This study was conducted to establish and document the implications of developing a computerized Loan Management System for the Savings and Credit Cooperative Organizations in Tanzania, by taking the case of the Ministry of Finance and Economic Affairs Savings and Credit Cooperative Organization. The study particularly sought to improve the availability of information and other services offered by the MoFEA SACCO to be much quicker, reliable and cost-effective following the limitatio...

Design And Construction Of A Microcontroller Based Five Degree Of Freedom Robotic Arm Using Servo Motors

ABSTRACT Integration of robotic arms into working tasks has currently increased magnificently in performing the very repetitive, dangerous or difficult tasks. Typically, a robotic arm is a mechanical arm that is programmable to mimic the behavior of a human arm in terms of how it functions. Computers and microcontrollers have widely been used in the control of robotic arms with the help of sensors, levers, buttons, wireless devices, just to mention but a few. More advanced technology has lat...
