ABSTRACT According to Hackman, Oldham (1976), Evaluation and performance appraisal is the major function of human resource department. A performance appraisal, employee appraisal and performance review are methods by which job performance of an employee is evaluated (generally in terms of quality, quantity, cost and time) typically by corresponding manager or supervisor. This is done through analyzing employees’ recent success and failures, personal strength and weaknesses and suitability f...
ABSTRACT Along with the changes in the world’s technology, Water became the backbone of industrialization and almost all the activities we carry out, rely on Water supply and demands of customers also change as well which has become more demanding and knowledgeable than ever before.”Water is life”. Consumers who consume Water units and Water services today are active and more critical in Water service delivery. This in turn made the management to shift their focus on the clients or cust...
ABSTRACT Registration management system has great impact on the day to day activities in most organization they among others they provide improved data accessibility, data integrity, security of information and so on. To day, the trend in most organization has shifted from the traditional and manual way of storing data to a modern and organized way. Because of the, Our lady seat of Wisdom (OLSW) could not be left behind and it flilly shares the advantages of database systems. Development meth...
ABSTRACT The occurrence of Entamoeba histolytica as a human intestinal parasite is a serious problem especially in developing countries. Entamoeba histolytica frequently infest as a commensal within the human large intestines with no overt clinical manifestations. However, trophozoites can invade the colonic epithelium and produce ulcers and dysentery, a condition known as Amoebiasis. Amoebic infections in Kyuso Zone, Kyuso District are common. The ecological aspects in the area and particula...
ABSTRACT Infant and young child feeding practices have substantial consequences for the growth, development, and survival of infants and children. Children should be exclusively breastfed for the first 6 months of life and thereafter continue to breastfeed for 2 years or longer. Children are vulnerable to malnutrition thus nutrition and health status of the confined children is of interest. The purpose of this study was to establish the feeding practices and the nutritional status of children...
ABSTRACT Rapid urbanization has resulted into substantial increase in quantities of sewage, which is traditionally discharged into the ocean, causing a number of environmental problems including threats to oceanic lives as well as ground water contamination. So far, there is limited data in Kenya regarding the toxic effects of sewage on benthic organisms. The aim of this study was to investigate the biogeochemical effects of sewage pollution on the mollusc Nerita polita by determining its im...
ABSTRACT Plant parasitic nematodes (PPN) are biotic constraints to crop production worldwide resulting in significant yield losses. Management of these nematodes has primarily depended on chemical nematicides; but due to the increased pressure for more economic and environmentally friendly strategies, alternative methods like organic and conventional amendments, have been considered. To test the efficacy of conventional and farmer practice systems against organic farming in the suppression of...
ABSTRACT Diabetes Mellitus is a condition with common elements of hyperglycaemia and glucose intolerance. It is the fourth leading cause of death in high-income countries and evidently epidemic in newly industrialized countries as well as economically developing nations such as Kenya. Type 2 Diabetes is characterized by insulin resistance and relative insulin deficiency. Studies have reported low serum chromium levels in Type 2 diabetics compared to non-diabetic population. Chromium has been...
ABSTRACT Tsetse flies (Glossina sp) are the vector of African trypanosomes, the causative agents of sleeping sickness in man and Nagana in cattle. The insect is strictly hematophagous, taking in significantly high quantities of water during bloodmeals that present a considerable osmotic challenge. This necessitates machinery for eliminating excess water. One potential candidate is a group of membrane channel proteins called aquaporins (AQPs) that are responsible for the movement of water acr...
ABSTRACT Food insecurity remains a major problem in poor households, and its implications worsen in disease states including Human Immunodeficiency Virus (HIV) and AIDS. More than 10 million Kenyans are chronically food insecure and 1.6 million have HIV. A synergistic relationship exists between food insecurity, HIV, and AIDS. Human Immunodeficiency Virus and AIDS cause an imbalance of the four fundamental elements of food security: food access, availability, utilization, and stability. Ther...
ABSTRACT The presence of toxic metals such as lead and Cadmium in the environment has been a source of worry to environmentalists, government agencies and health practitioners. This is mainly due to their health implications since they are non-essential metals. Heavy metals are associated with various soil components in various ways and the various associations can determine the reactivity, mobility and bioavailability of the metals. The primary objective of the present study was to determine...
ABSTRACT The World Health Organization estimated annual global malaria mortality to be at 405,000 deaths in 2018 making malaria one of the most important diseases in the world. In Kenya, malaria control measures have been put up, however, the ongoing climate change and climatic variability is proving to be a great challenge. The aim of this study was to investigate the impact of climatic variability and malaria control interventions on malaria parasite prevalence and vector abundance in west...
ABSTRACT Infectious diseases account for approximately one-half of all deaths in tropical countries. In industrialized nations, despite the progress made in understanding of microbiology and their pathogenic control, incidences of epidemics due to drug resistant micro-organisms and the emergence of hitherto unknown disease causing microbes, pose enormous public health concerns. Thus, there is need to continue the search for appropriate drugs for anti-microbial treatment without much drawback...
ABSTRACT The analysis of cellophane sheet as a phase retarder is reported. Several cellophane sheets were tested for birefringence and compared with a purpose built half wave plate (HWP). A Mach-Zehnder interferometer was used to generate interference patterns when the cellophane sheet was half-way mounted on one arm of the interferometer. Analysis of the interferograms revealed a clear phase shift which was calculated to be 0.98π. The fast axis was determined to be along the length of the c...
ABSTRACT The concept of cycle index was first discovered by Howard Redfield in 1927. The cycle index formulas of various group actions have been computed since then by various authors. The formulas have been used to count graphs in mathematics and chemical compounds in chemistry. Therefore cycle index is a very useful tool in enumeration. It is widely applied in other fields of study like biology and jewelry industry. The cycle index of the symmetric group acting on ordered pairs, triples an...
