Enhancing Farmers' Agricultural Productivity Through Improved Field Management Practices In The Central Highlands Of Kenya

ABSTRACT Farmers in central highlands of Kenya have been experiencing declining crop yields in the recent past. Low water availability caused by low and unreliable rainfall, and poor water harvesting techniques coupled with low soil fertility are key constraints to crop production in these regions. To increase crop yields, and reduce production risks, better use of available rainfall is required. The broad objective of the research was to enhance farmers' agricultural productivity through im...

Prevalence, Susceptibility Patterns And Risk Factors Associated With Staphylococcus Aureus Presence In Marketed Milk And Milk Products Within Nairobi City County, Kenya

ABSTRACT Staphylococcus aureus is a major food-borne pathogen that poses a serious threat to public health. In Kenya, with the continuous water shortage, proper sanitary conditions are not sufficiently met and hence pre-disposing the community to S. aureus infections. One of the difficulties of controlling S. aureus food poisoning is that food can contain a very high population of the bacteria without being noticeably identified. It has been suggested that food-borne diseases represent one of...

Extensions Of The Field Of Rational Numbers Whose Galois Group Is Isomorphic To A Group Of Order Eight

  ABSTRACT The Galois group of a certain type of field extension is a specific group associated with the field extension. The study of field extensions and their relationship to the polynomials that give rise to them via the Galois groups came to be called Galois Theory in honor of Everiste Galois who first discovered them in 1830. In this project we find the extensions of whose Galois group is isomorphic to, , and the quaternion group . In each case we identify the extension, then work ou...

In Vivo Antidiabetic Effects And Safety Of Five Medicinal Plants Traditionally Used To Manage Diabetes Mellitus In Embu County, Kenya

ABSTRACT Diabetes mellitus is a glucose metabolism disorder that has become an issue of public health concern in Kenya today. Conventional drugs used in management of the disease are unaffordable to the general populace and are associated with many undesirable side effects. Locally made herbal extracts are cheap and readily available but proper scientific study has not been conducteed on most medicinal plants to validateK their efficacy and safety.

Evaluating The Occurrence Of Schistosoma Haematobium And Geohelminthes Infection In Residents Of Two Villages In Msambweni District Of Coast Province, Kenya.

ABSTRACT The presence of multiple concurrent infections, or polyparasitism, is quite common in schistosomiasis endemic areas. Msambweni District in the Coast Province of Kenya is highly endemic for Schistosoma haematobium. Previous studies showed an overall prevalence of schistosomiasis in Msambweni District at 40% to 60%. This is a prevalence way above the national prevalence of approximately 23%. There has been continued support by various agencies, including the government and non-governme...

Evaluation Of Passive Immunity To Schistosomiasis In Mice Transfused With Hyper-Immune Baboon Serum

ABSTRACT Schistosomiasis is a tropical disease caused by worms in the genus Schistosoma. It remains one of the most prevalent parasitic infections and has significant economic and public health consequences. Despite having an effective chemotherapeutic drug, praziquantel, there is still need for a vaccine since the immediate manifestations in most people are negligible or indeterminate. Several antigens have been tested as vaccine candidates with largely disappointing results. Both rodents a...

Spatial temporal analysis of the distribution of pediatric tuberculosis patterns in Kenya

ABSTRACT Tuberculosis is a leading cause of mortality and morbidity globally. Kenya is among the 22 high burden countries that contribute 80% of the global burden and is ranked number 15 worldwide while in Africa, it is ranked number five. Among children, it is a top 10 cause of mortality. However children with TB are given low priority in most national health programs and are a neglected group in this epidemic. This is because from a TB control point of view, they rarely transmit the disease...

Derivation Of Cycle Index Formulas Of Semidirect Product Groups

Abstract The concept of the cycle index formulas of a permutation group was discovered in the year 1937. Since then cycle index formulas of several groups have been studied by di_erent scholars. For instance the cycle index of the dihedral group Dn acting on the set of vertices of a regular n􀀀gon is known and has been applied in enumeration of di_erent mathematical structures. In this study the relationship between the cycle index formula of a semidirect product group and the cycle index f...

Bioprospecting For Hypoglycemic Activities And Safety Of Selected Traditionally Used Plants In The Management Of Diabetes Mellitus

ABSTRACT Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar levels that result from defects in insulin secretion, or action, or both. The disorder completely throws the metabolism of dietary carbohydrates, lipids and proteins into disarray. This condition in its fully developed form is characterized by high blood sugar level (hyperglycemia), glycosuria, increased protein breakdown, ketosis and acidosis. Diabetes is a chronic medical condition which can be co...

Effect Of Room Temperarure Storage On The Levels Of Carotenoids, Total Phenolic Content And Antioxidant Activity Of Lycopersicon Esculentum And Citrullus Lanatus

ABSTRACT Noncommunicable diseases (NCDs) such as cardiovascular disease, cancer and chronic respiratory diseases are economically burdening, causing more deaths worldwide than all other causes of death combined. The global burden of these diseases is projected to increase tremendously with an estimated global death of 75 % by 2030. Unhealthy diets, tobacco use, exposure to environmental carcinogens and physical inactivity are documented as the major causes of NCDs. The major contributing fact...

Structure-repellence studies of δ-octalactone analogues and blends against tsetse flies, glossina pallidipes and g. Morsitans morsitans

ABSTRACT Tsetse flies (Glossina spp.) are serious vectors of trypanosome parasite, threatening over 60 million people with Human African Trypanosomosis (sleeping sickness) and 45-50 million cattle with Animal African Trypanosomosis (Nagana) annually in the sub-Saharan Africa. It is estimated that 50,000-100,000 people and 3 million cattle die from trypanosomosis annually. Studies on vaccine development for parasite control have proved unsuccessful due to antigenic variations of the parasite....

Nutrition Knowledge, Attitude, And Practices In Management Of Stage 5 Chronic Kidney Disease By Adult Patients At Kenyatta National Hospital, Kenya

ABSTRACT Stage 5 Chronic Kidney Disease (CKD) is the fifth stage of the quiet stages of Chronic Kidney Disease. Optimal nutrition, medical treatment and management are inevitable in improving the quality of life, reducing morbidity and thus mortality of the patients. While there is no clear data on prevalence and incidence rates in Kenya and most developing countries, Kidney Disease is one of the most serious and currently emerging non-communicable diseases and continues to undermine the heal...

The Effects Of Hydrological Characteristics Of River Nyakomisaro On The Water Supply Of Kisii Municipality, Kenya

ABSTRACT Research was carried to explain the variation in the hydrological characteristics of river Nyakomisaro and its effect on water supply in the Kisii Municipality. The study determined the variability in rainfall and river discharge in the Nyakomisaro sub Catchment, established the relationship between rainfall and streamflow in the sub catchment, examined the extent for which River Nyakomisaro water was used in supplying water to the Kisii Municipality and examined the streamflow mana...

Contamination Levels Of Groundwater, Antimicrobial Resistance Patterns, Plasmid Profiles And Chlorination Efficacy In Ongata Rongai, Kajiado North County, Kenya

ABSTRACT Water contamination is a serious threat to human health especially if the contaminant is from sewage. Ground water is increasingly used as a water source in urban settlements due to limited sources of fresh surface water. This has increased the vulnerability of underground water sources to sewage and waste water contamination and therefore exposing the population to infections by various water borne pathogens such as bacteria, viruses and protozoa. Exposure to these bacteria coupled ...
