    The effects of online retailing on business success; a case study of Nakumatt Holdings Supermarket
    (Kampala International University, College of Economics and Management, 2010-07) Raduk, Alex O.
    The study was to establish the role of Online retailing on the success of a business enterprise. The study was conducted at Nakumatt Holding supermarket in Kenya. It was guided by the following objectives; to find out the perception and nature of online retailing, to determine the feasibility of online retailing. To determine the target market group of customers that will opt for online buying and finally to determine the obstacles of online retailing. The study went furthers to examine which customer profile would be attracted to shopping online. The data was obtained from primary data sources such as: interviews, questionnaires, telephone surveys, fieldwork and observation. The data was also obtained from secondary data such as newspaper articles, magazines, journals, published books and internet. According to the findings the study there was conclusive evidence that electronic retailing would not be very successful if introduced in Kenya at the moment. This is because there are many constraints that will hinder the growth of online retailing. The predominant problem is the lack of inaccessible avenue (lack of accessibility to the credit card facilities) with majority of the respondents citing this as the main constrain to online retailing transactions. However, both individuals and business firms see the viability and future potential of online retailing as certain. The study recommended that international development organizations should study the potential impact of online retailing on emerging economies a.nd the least developed countries in an effort to assist in the economic development process of those nations. The study went further to suggest areas of further studies. The areas identified are as shown below. Computer purchases, credit cad usage, proliferation of computers in Kenya especially the urban areas. The relationship between the informal sector and the digital economy needs to be further examined. This could be an important area of policy research.

    The effectiveness of moringa oleifera coagulant in the treatment of drinking water
    (Kampala International University, College of Engineering and Applied Sciences, 2017-09) Makoona, Zubairi
    This research study aimed at assessing the effectiveness of Moringa oleifera coagulant in the treatment of safer, cleaner, adequate and cheaper drinking water for all Ugandans. Water samples from Lake Victoria and hand dug wells both found in Ggaba were treated using Moringa oleifera and Alum coagulant in different sets according to ISO 9308 1-1 and Association of Official Analytical Chemist (AOAC) jar test procedures. Then pH, turbidity, conductivity and total coliform levels of water samples before and after treatment with 5Omg/L, 75mg/L and 1 OOmg/L of Moringa coagulant in the first set were measured and compared with that treated using 5Omg!L, 75mg/L and 1 OOmgIL of alum coagulants in the second set. Control experiments (water without both coagulants) were included in the first set and their water parameters were also determined. Efficient turbidity reduction was observed at 75mg/L concentrations of Moringa for lake and well water from an initial value of 126. 12NTU to 3.65NTU and 98.84NTU to 3.45NTU respectively. Alum concentration of lOOmgIL reduced turbidity to 1 .92NTU for Lake Victoria water and 2.83NTU for well water samples. Conductivity gradually increased for both coagulants with increasing concentrations but ranged within the WHO standards for the drinking water. Moringa concentrations did not influence pH of water. The pH values were observed to range between 7.61 to 7.06 for lake water and 6.88 to 6.58 for well water, however, alum concentrations reduced pH drastically. Bacterial removal of 76.47% and 86.67% was observed for 75mgIL of Moringa oleifera concentration for lake and well water samples respectively whereas alum coagulant of 75mg/L concentration recorded 52.94% and 66.67% bacterial removal for lake and well water samples Findings from this study indicate that Moringa oleifera coagulant at optimum dosage of 75mg/L can be a potentially viable substitute to alum as a coagulant in the treatment of the drinking water.

    Estimation of sucrose loss due to inversion process as a result of multiple effect evaporation
    (Kampala International University, School of Engineering and Applied Sciences, 2017-09) Muwanika, Ibrahim
    A major aim of this research project has been to quantify industrial sucrose losses due to inversion in multiple effect evaporators. This paper discusses new insights gained from this project on sucrose losses in sugarcane juices and syrups at high temperatures during different evaporation and clarification processes. In general, for the factory most sucrose inversion losses occurred in the pre-evaporators and were more of a function of temperature, pH and retention time (R.). Sucrose inversion only occurred in later evaporator bodies when scale had built up. Increasing the factory target pH of the clarified juice (Ci) or final evaporator syrup (FES) systematically reduced losses of sucrose and a target FES pH of 6.5 - 6.8 (equivalent to a target CJ pH of 7.0-7.2) is recommended; however, scaling effects can override pH effects.

    Assessment of selected pollution indices of domestic wastewater discharge from kira town council, Wakiso.
    (Kampala International University,School of Engineering and Applied Sciences, 2017-09) Waiswa, Herbert
    This study focuses on the temporal monitoring and analysis of wastewater from Kira Town Council. The distribution of the chemical constituents major and minor is determined and compared with National Environment Management Authority (NEMA) Standards of wastewater discharge on land and into water bodies. The obtained results indicated that most of collected wastewater samples exceeded the acceptable limits set by standards used for most parameters determined. The wastewater parameters tested for included the following; BOD, COD and the major chemical pollutants nitrogen as animoniacal nitrogen and organic nitrogen, phosphorus. The majority of waterborne microorganisms that cause human disease E coli was also tested for in this research. The research used both qualitative and quantitative methods of data collection. The major objective was to generate information, which could subsequently be applied by stakeholders to improve management and protection of the environment, and improve the health of Kira community. Majority of the people in Kira discharge their wastewater into drainage channels, on open ground indiscriminately. Only a small fraction use septic tanks and soak pits. Poor drainage and odors were some of the many problems resulting from mismanagement of wastewater.

    Determination of gold concentration in the gold ore in Lujinji, Mubende district:
    (Kampala International University, School of Engineering and Applied Science, 2017-10) Karungi Fiona
    This study is aimed at determining the concentration of gold in the gold ore in lujinjimubende district. Currently investing in gold mining is taken as a riskyinvestmentbecause people are not sure of the concentration of gold in lujinji and also the depth where gold concentration is high. The results of this research gave the concentration of gold in lujinji and also the depth of high concentration from the surface, which eased the mining activity by extracting gold at a known height and also determine whether lujinji as a mining area qualifies for commercial mining. Samples were collected from different shafls at different heights in meters, they were taken to geological survey and mines Entebbe for size reduction to fine particles and finally they were taken to Makerere University in the department of geology for sample preparation and analysis. The concentration of gold at different heights was analyzed and it was found out that gold is present in the lujinji and proved to be more concentrated at 200m and therefore arrange of 1 OOm to 500m can be considered. Further studies need to be carried out to determine the levels and concentration of gold in other gold areas and also on other metals like silver, lead, which was not covered in this study and also lujinji as an area qualifies for commercial mining according to the price of gold on the world market.

    Effect of flocculant on scale formation in evaporators
    (Kampala International University, School of Engineering and Applied Science, 2017-10) Wamuke Nickson, Nasila
    Scale formation has become a big burden to sugar manufacturing industries especially in evaporators, this is because of the characteristics of cane juice which is allowed in evaporators. Evaporators are used to evaporate as much water as possible from the juice using exhaust steam from the power house as the heating medium so as to concentrate the juice which is called syrup (that is the juice leaving the evaporator) and the juice entering the evaporator is termed as clear juice. Scale normally deposits inside the calandria tubes of the evaporators and this is brought by the constituents which are contained in the cane juice these include; insoluble solids, non-sugars, sulphates, gums, waxes which are the major sources scaling in the evaporators. The effect of scaling is to reduce the convective heat transfer between the tubes and the juice which in turn reduces the capacity of the evaporators hence reducing the efficiency of the evaporators. Therefore, this report focused on the immediate remedy of how to either stop or reduce scale formation in the calandria tubes of the evaporator so that evaporator efficiency is improved. Results show that the quantity (concentration) of flocculant used in the clarifier before allowing juice to enter into evaporators this flocculant attracts insoluble solids forming heavy flocs which settle down the clarifier and allowing only clear juice to enter the evaporator.
