    Construction of A Force Pump as a Teaching Aid.
    (Kabale University, 2021) Muhwezi, Abel
    The project was about the construction of a force pump as a teaching aid using locally available materials. The project used materials that included a syringe that acted as a cylinder with a piston having a handle; a bottle of soda that acted as a reservoir, two valves of a bicycle tire, panga, a container with water used as the water source, pipes, and a wooden stand. During the construction of a force pump, A syringe with a piston was assembled with two valves of a bicycle tire. The syringe that acted as a cylinder with a piston and the reservoir was then mounted onto the wooden stand that enabled the force pump to operate properly under the principle of up-stroke and down-stroke. The inlet valve B and the outlet valve A were fixed in a way that during the upstroke, valve B opened and valve A closed, then during the downstroke valve B closed and valve A opened. During the upstroke, the piston drew water through an inlet valve B into the cylinder while on the down stroke, the water was discharged through an outlet valve A into the reservoir thus water was obtained through the spout.

    Stigating Newton's Interpolation and Lagrange Method Compared to Runge Kutt A Method in Solving First Order Differential Equations.
    (Kabale University, 2022) Gumisirlza, Catheline
    This study investigated Newton's Interpolation and Lagrange method as compared to Runge Kuta's method in solving First Order Differential Equations. It follows research questions that include quicker and faster methods of solving first-order differential equations using Newton's interpolation and Lagrange and method of solving first-order equations using Runge-Kutta with increased accuracy comparing Newton's interpolation, and Lagrange. Study results indicate that for instance for y(0.01) in example l a combination of Newton's interpolation and Lagrange gives an absolute error of 0. 00009901. Runge Kutta's second order gives an absolute error of 0.00989951. For y(0.01) a combination of Newton's interpolation and Lagrange gives an absolute error of 0. 000084 as compared to 0. 024613585 absolute error obtained by Runge Kutta second order and the study recommends that the Numerical method used (Runge Kutta) is cumbersome and has a bigger percentage error. I therefore recommend the use of combined Newton's interpolation and Lagrange method to solve . Therefore the combination of Newton's interpolation and Lagrange gives a high accuracy as compared to Runge Kutta's second order. A combination of Newton's interpolation and Lagrange is a simpler method to use since it has less iteration as compared to Runge Kutta's second order.

    A Mathematical Model For The Dynamics of Polio.
    (Kabale University, 2021) Owobusingye, Johnan
    There is a lack of treatment for poliomyelitis and it is only prevented through immunization with live oral polio vaccine (OPV) or/and inactivated polio vaccine (IPV). Poliomyelitis is a very contagious viral infection caused by poliovirus. Children are principally attacked. In this project, we assessed the impact of vaccination in the control of the spread of poliomyelitis via a deterministic SVElR (Susceptible-Vaccinated-Exposed-Infectious-Recovered) model of infectious disease transmission, where vaccinated individuals are also susceptible, although to a lesser degree. Using Lyapunov-Lasalle methods, we proved the global asymptotic stability of the dynamics of the disease whenever Ra < I. Numerical simulations, using poliomyelitis data from Kabale Regional Referral Hospital in Kabale district, have been conducted to approve analytic results and to show the importance of vaccination coverage in the control of disease spread.

    Mathematical Modelling of Cholera Transmission incorporating Media Coverage.
    (Kabale University, 2019) Muhereza, Obed
    Cholera is a gastrointestinal disease caused by a bacterium called Vibrio cholerae. The spread of the disease depends largely on social and environmental factors such as, eating food or drinking water contaminated with feaces from an infected person. Cholera outbreaks, for instance, in Uganda have led to deaths and hospitalization. Since cholera spreads and kills very fast, the effectiveness of control strategies such as vaccination, water chlorination and therapeutic treatment may be enhanced by the use of media alert and awareness campaigns. This aspect has not been considered in existing cholera models. In this study, the impact of media coverage on the spread of cholera was investigated using a mathematical model. The specific objectives of the study were to construct a mathematical model for cholera transmission incorporating media coverage, to analyse the stability of equilibrium points of the model and to evaluate the role of media coverage as a disease control strategy. Positivity and boundedness of solutions was established to ensure that the model was biologically meaningful. The model was thereafter analyzed using the stability theory of differential equations. The basic reproduction number Ra, was derived using the next generation matrix approach. The existence of equilibrium points of the model was determined. The results of stability analysis showed that the disease free equilibrium was locally asymptotically stable when R< 1 while the endemic equilibrium was locally asymptotically stable when R> 1. p which is the efficacy of media coverage has an inverse relationship with the spread of the disease, such that whenever it is high, the disease spread reduces and when it is low, the disease spread increases. This implies that, media alert and awareness campaigns are vital in controlling the spread of cholera. Based on this study, it is recommended that health practitioners embrace the use of efficacious means of media coverage to publicize awareness campaigns of an outbreak and the preventive measures.

    Effect of Supervision on Employee Performance in Uganda: A Case Study of Shuuku Savings Cooperative SACCO in Sheema District.
    (Kabale University, 2019) Ayesiime, Peninah
    This research report was undertaken at Shuuku Savings Cooperative Sacco in Sheema District to establish the effect of Supervision on Employee Performance in Uganda: A Case Study of Shuuku Savings Cooperative Sacco in Sheema District and emphasis was also put on the different objectives namely the effect of supervision on administrators performance in Shuuku SACCO and to analyse the effect of supervision on other employee performance in Shuuku SACCO. The study employed a descriptive research design which employed both quantitative and qualitative research approaches. The study sampled 28 respondents from the target population of 32 who work with Shuuku Sacco in Sheema District. The study employed the questionnaire and the interview guides to collect data from sampled respondents in Shuuku Sacco. The research findings show that Supervision also helps administrators in learning on new ways of how to do things, supervision helps in providing a gap within the employee performance, and therefore after that gap has been realised it will promote learning in the SACCO. Supervision affects the skills of subordinates. On the other hand, poor supervision has an effect on efficiency at work according to the study whereas the majority of the respondents agreed to the idea that there is a relationship between supervision and employee performance. The study therefore recommends that Staff job satisfaction should be the top priority of supervisors. It further recommends that Supervision must be more of ideas sharing and participatory than conventional or control oriented in order to improve on performance.

    Comparison of Variation of Vitamin C Content with Ripening Stages in Fruit Extracts of Solanum Gilo, Solanum Anguivi And Solanum Aculeastrum.
    (Kabale University, 2022) Ayebare, Happiness
    Investigation of change in the amount of vitamin C in S. aculeastrum, S. anguivi, and S. gila as a result of ripening time involved titration of aqueous extracts from green, yellow, and red fruits separately using potassium iodate. The results obtained showed the content of vitamin C in green fruits which varied as follows; aculeastrum: 0.0088M, S.anguivi: 0.0077M, and S. gila: 0.0061M. The yellow fruits had S. aculeastrum: 0.0073M, S. anguivi: 0.0062M, and S. gilo: 0.0046M, and red fruits had S. aculeastrum: 0.0058M, S. anguivi: 0.0047M, and S. glo: 0.0003M. The data revealed a decrease in the concentration of vitamin C in fruits that turned green from yellow to red. In dietary terms, these fruits should be consumed when green because in that form they contain the highest concentration of vitamin C.

    Mathematical Modelling of the Transmission of Malaria.
    (Kabale University, 2019) Atubangire, Felix
    In this report, we present a mathematical model for the transmission of malaria by female anopheles mosquitos. We determine the invariant region in which our model system lies. We clearly show the mechanism by which malaria spreads from one person to another. The model takes in the ordinally differential equations. The basic reproduction number Ro is obtained. A stability analysis of the disease-free equilibrium was carried out for the case where there is no malaria in the population. Sensitivity analysis of the parameters to basic reproduction number. The results show that the basic reproduction number Ro is more sensitive to natural mortality. All working steps are included.

    Effect of Tax Payment on Performance of Small-Scale Businesses in Uganda: A Case Study of Bwambara Sub-County Rukungiri District.
    (Kabale University, 2019) Akampurira, Space
    The study was about the effect of taxes on the performance of small-scale business enterprises in Uganda; A case study of Bwambara Trading Centre in Rukungiri district. A descriptive design and exploratory design were used depending on the characteristics of the study. A sample of 88 respondents was used, and data was collected using a questionnaire directed to the owners of small-scale enterprises in the area. Data was analyzed and summarised using frequencies where percentages were derived for easy interpretation. The findings of the study revealed that taxations promote funding of governments; it also affects the savings and investments of business operators. The study also revealed that taxation also causes some business people to lose jobs, and also makes increments in prices for goods and services in SMEs. The study recommends that the Government through the Ministry of Finance Planning and Economic Development call for workshops, seminars, and radio programs to educate the business community about the different forms of taxes imposed on small-scale businesses. The study revealed that the biggest problem with the tax paid is in fact that the SME community does not understand how the tax is arrived at as well as how it is paid but not because it is too high.

    Variation of Nutrient Content in Different Irish Potato Varieties with Storage Time in Kabale District.
    (Kabale University, 2019) Nshimyimana, Evarist
    This study investigated the variation of Irish potato nutrients with storage time in Kabale municipality, kabale district. Two Irish potato varieties were selected based on common Irish potatoes grown in the area. 20 Irish potatoes from stems of two different varieties were collected from a garden. Four of the fresh Irish potatoes were peeled on arrival in the laboratory immediately. One piece of about 100g was cut from the peeled Irish potatoes and then pounded in the motor, 100ml of water was added to the products to obtain the potato extract. This was filtered the concentration of reducing sugars was determined using Benedict's solution by titration method. The same was done for the remaining 12 Irish potatoes for every two weeks. The concentration of vitamin C in each of the Irish potato extracts was· determined by redox titration of the extracts with standard acidified potassium iodate solution in the presence of potassium iodide using starch indicator. The study found out that the concentration of vitamin C reduced with storage time while the concentration of reducing sugars increased with storage time maybe because, towards germination, starch was being changed to reducing sugars.

    Effect of Temperature on The Concentration of Ascorbic Acid in Three Selected Varieties of Cabbage Sold in Kabale Municipality Kabale District.
    (Kabale University, 2021) Bagambaki, Paul
    Cabbage, a member of the genus Brassica is among the vegetable crops cultivated and eaten by people all around the world because of its nutritional, medicinal, and lucrative purposes. The high prevalence of ascorbic acid deficiency known as scurvy mainly among the children in Kabale municipality called for the investigation of cabbage varieties with a considerable concentration of this acid to cure this kind of deficiency. Therefore, this study aimed at determining: the variety of cabbage with high ascorbic acid concentration among the three commonly eaten and sold varieties of cabbage in Kabale municipality; and the effect of temperature on the concentration of ascorbic acid in these varieties. The concentration of ascorbic acid in the three selected cabbage varieties (red, green, and white) was determined by redox titration of the solutions extracted with a standard solution of potassium iodate in the presence of potassium iodide, hydrochloric acid, and starch indicator. The sample solutions were extracted from the cabbage varieties and the ascorbic acid concentration was analyzed in the raw cabbage samples and samples incubated for fifteen minutes at temperatures of 50 °C, 70 °C, and 100 °C using a water bath. The results obtained from the raw samples of cabbage varieties indicated that the concentration of ascorbic acid was in the order of red > green > white (94.62±0.42, 73.37±0.63, 58.71±1.10 mg/100 ml respectively). The percentage loss in ascorbic acid increased with an increase in temperature i.e., (15.63-19.21 %), (26.83-53.44 %), and (54.89-71.39 %) for 50 °C, 70 °C, and 100 C temperatures respectively. From the findings of this study, it can be concluded that the red cabbage variety is the best source of ascorbic acid among the three varieties of cabbage. Cabbages should be boiled at relatively lower temperatures for them to retain much of the ascorbic acid.

    A Mathematical Model For The Population Dynamics Of Disease Transmiting Vectors in Particular Female Anopheles Mosquitoes.
    (Kabale University, 2019) Turyamusiima, Richard
    In this paper we present a mathematical model of population dynamics of female anopheles mosquitoes. The threshold dynamics of this model is determined and the stability of equilibrium points have been obtained using the jacobian matrix. The mosquito free equilibrium and endemic equilibrium have been determined by setting system of ordinary differential equations to zero. Basic reproduction has been determined using the next generation matrix management analyzed. Hence. we show that if the threshold dynamics quantities are less than unity, the mosquitos' population decreases to zero but if they are greater than unity, mosquitos' population persists.
