Item Antimicrobial activities of Tithonia diversifolia and Kigelia africana against Fusarium oxysporum in tomatoes(Chuka University (Journal of Environmental Sustainability Advancement Research), 2021) Awere, C. A.; Githae, E. W.; Gichumbi, J. M.Fusarium wilt disease caused by the soil-borne fungus Fusarium oxysporum Schlechtthe is a serious threat to tomato production worldwide. Chemical and cultural methods of management used are either ineffective or toxic to the environment. Plant secondary metabolites; therefore, pose a possible alternative because they are environmentally friendly and have minimal effect on non-target organisms. This study screened phytochemical compounds of two plants; Tithonia diversifolia and Kigelia africana and assessed their potency in controlling plant fungal pathogen F. oxysporum, the causative agent of Fusarium wilt disease in tomatoes. Leaf extracts of T. diversifolia and fruit extract of K. africana were used in this study becauses they are readly available and the plnts have been used in the treatment of varius diseases in humanbeings. The plant etract were concentrated in water and screened for phytochemical contents using standard procedures. Concentrations used were 25 g/L, 50 g/L and 100 g/L to sock the disc. Fusarium oxysporum was isolated from infected soil using potato dextrose agar media while the antifungal activity was evaluated by measuring the zone of inhibition against the test organism. In determining the antimicrobial properties of each of the plant extract, a 3×3 randomised complete block design was used, replication was done 3 times. The results showed that the mean inhibitory zones were highest at 100g/l in both plants, although K. africana fruit extract portrayed the higher inhibitory activity compared to Tithonia africana. The effect of the plant extracts and the positive control were statistically significant (pα0.05). This study indicates that K. africana and T. diversifolia possess the antifungal activity and can be used as a broad-spectrum fungicide against F. oxysporum. The effect of the plant extract was statistically significant (p<0.05). The Mean of inhibition ranged from 23.67 to 7.78 mm for Tithonia diversifolia and 23.67 to 11.75 for Kigelia africana. While for the combined extract the The Mean of inhibition ranged from 22.78 to 7.93 . The minimum reduction in sporulation was recorded in the positive control, which was significantly lower than the rest of the treatments.These plant extracts may provide an effective measure for the management of Fusarium wilt of tomatoes that may form an integral part of integrated pest management and become a prospect alternative to conventional fungicides.Item Application of Simplex Lattice Designin Watermelon Production(Chuka University, 2019) Muriithi,Dennis K.This paper discusses the use of Simplex Lattice Design approach to plan the experiment for yield of watermelon with an overall objective of optimizing the multiple responses of watermelon to organic manure. Multiple linear regression models have been adopted to express the output parameters (responses) that are decided by the input process parameters. Poultry manure, cow manure and goat manure were the independent variables to optimizethe response values of interest that includes; watermelon fruit weight, number of fruits of watermelon per plant. Mixture experiments are appropriate to use when a researcher wishes to determine if synergism exists in mixing components which increases productivity. Three-component design presented in this study illustrated how to applymixture designs inagricultural research. Mathematical Model evolved for response showthe effect ofeach input parameter and its interaction with other parameters, depicting the trend of response. From, the equation of fruit weight and number of fruits, it canbe concluded that goat manure has a more important role on watermelon production in the current study. Conclusively, the current study attained the optimal condition of 17.68 ton/Ha, 11.69 ton/Ha and 19.16 ton/Ha of poultry manure, cow manure and goat manure respectively, would guarantee the farmer a maximumyield of22.13kgfruit weightof watermelonper plantand 7.74≈8 Fruitof watermelonper plant. The study exemplified that the development of statistical models for crop production can be useful for predicting and understanding the effects of experimental factors.Item BIOC 313: NUTRITIONAL BIOCHEMISTRY(Chuka University, 2023-12-19) Chuka UniversityItem BIOC 313: NUTRITIONAL BIOCHEMISTRY(Chuka University, 2023-12-19) Chuka UniversityItem BIOC 313: NUTRITIONAL BIOCHEMISTRY(Chuka University, 2023-12-19) Chuka UniversityItem BIOC 313: NUTRITIONAL BIOCHEMISTRY(Chuka University, 2023-12-19) Chuka UniversityItem BMET 110: HUMAN MORPHOLOGY AND DEVELOPMENTAL ANATOMY(Chuka University, 2023-04-20) Chuka UniversityItem BMET 230: MEDICAL AND VETERINARY ENTOMOLOGY(Chuka University, 2023-12-19) Chuka UniversityItem BMET 230: MEDICAL AND VETERINARY ENTOMOLOGY(Chuka University, 2023-12-19) Chuka UniversityItem BMET 444: BIOMEDICAL INSTRUMENTATION(Chuka University, 2023-04-20) Chuka UniversityItem BOTA 131: GENERAL MICROBIOLOGY(Chuka University, 2023-12-19) Chuka UniversityItem Burn-Out as a Psychological Effect of Widow hood in Meru County,Kenya:Comparative Study of Widows and Widowers(Journal of Education and Practice, 2018) Mburugu,Beatrice MWidowhood is a state of losing a spouse through death and has been on the increase in Kenya and all over the world. A spouse’s death is traumatic and affect the widowed persons’ psychological well-being, as they go through the various stages ofbereavement. They maybecome withdrawn, less motivated, become frustrated and isolated which may affect their mental and physical wellbeing when burn-out sets in. There may be adverse effects of widowhood that are psychological since the widowed persons may rate themselves low, have disturbing memories and fatigue after the death of the spouse whom they shared life with. In Meru community, no research has been done on the psychological effects of widowhood yet widowhood is traumatic and a common phenomenon in the community. Therefore, the purpose of this study was to determine thepsychological effects of burn-out by comparing widowed men and women in Meru County Kenya. A literature gap existsinKenya onburn-outof widowed menand womenthus motivatingthe author to come up withsuch a study. Therefore, the objective of this study was to determine burn-out as a psychological effect of widowhood by comparing widowed men and women in Meru County Kenya.Expostfacto’s causal-comparative research design was considered appropriate for the study because of comparison of groups. A sample of 384 widowed persons (192 widows and 192 widowers) in four Districts that were purposively selected making a total of 384 respondents. Data was collected by use of questionnaires which were administered to widowed persons and two Focus Group Discussions for widowed persons were held in each of the four selected Districts; one for the widowers and another for widows. Data analysis was done by use of descriptive and inferential statistics. Inferential statistics included t-test which was used to establish whether differences in burn-out as a psychological effect existed between widowed men and women. Descriptive statistics that included frequencies, means and percentages were also used. The findings revealed variations in the widowed persons’ psychological effect of widowhood where widows showed high levels of burn-out than widowers. From thefindings, it is evident that absence of either of the spouse negatively affects the mental and physical wellbeing of the living spouse especially widows. Counselling programmes of widowed persons in the country are needed to assist and empower themespeciallywidows whoare notallowedtoremarry.Itisthereforerecommendedthatthe Ministry of gender, religious organisations, service providers and other stakeholders should use such programmes to address psychological needs of widowed persons. Finally, the findings mayassist the widowed men and women tocopebetterpsychologicallywiththeirstateofwidowhoodwhichistraumatizingastheyattachmeaninginlife and bring up their families single handedly.Item CDEV 436: FAMILY LAWS AND POLICIES(Chuka University, 2023-12-19) Chuka UniversityItem CDEV 00140: BASISC FUNCTIONS OF MANAGEMENT(2023-04-13) CHUKA UNIVERSITYItem CDEV 0140: BASIC FUNCTIONS OF MANAGEMENT(2023-04-13) CHUKA UNIVERSITYItem CDEV 0141: PRINCIPLES OF DISASTER MANAGEMENT(0023-04-13) CHUKA UNIVERSITYItem CDEV 0205: NETWORKING, LOBBYING AND ADVOCACY(0023-04-11) CHUKA UNIVERSITYItem CDEV 0262: DEVELOPMENT ADMINISTRATION(CHUKA UNIVERSITY, 2023-08-30) CHUKA UNIVERSITYItem CDEV 0270: RURAL ECONOMICS AND AGRICULTURAL EXTENSION(CHUKA UNIVERSITY, 2023-04-13) CHUKA UNIVERSITYItem CDEV 141:HUMAN DEVELOPMENT(0023-04-13) CHUKA UNIVERSITY
