A Secure Cloud-Based Academic Enterprise Resources Planning (Caerp) Model for Higher Institutions “A Case Study of Kampala International University, Uganda”

ABSTRACT Academic Enterprise Resource Planning (ERP) systems are meant to integrate the separate activities, processes, and functions within a higher institution to help streamline the process and to provide real-time, on-demand information needs. The volume of data produced by academic institutions grows every day. Due to the increasing numbers of staff, students, departments, and programs, this continuous growth requires continuous scaling and improvement of the academic ERP system. Therefo...

Assessment of Levels of Heavy Metals in Water and Colloid Samples from River Oyun

Heavy metals have been a defining parameter concerning water quality. They have constituted a major degree in pollutants levels in the environment. The study was designed to investigate the comparative levels of heavy metals in colloidal and water samples in relation to the activities on the River Oyun and the activities around the sampling location. The samples were analyzed for six metals using Atomic Absorption Spectrophotometry. The results obtained showed that the concentrations of ...

Investigation of The Physicochemical, Microbial and Trace Metals Properties of Selected Packaged Drinking Water Sold in Kansanga, Kampala, Uganda.

ABSTRACT This study aimed at investigating the physicochemical and microbial properties of Packaged Drinking Water, sold in Kansanga, Kampala. Seventy-two samples were selected by systematic random sampling from local stores in the study area. Three types of Packaged Drinking Water samples (bottled, sachet and handtied) were selected. Spring water samples were used as control samples. Titrimetric techniques were used to determine the Chlorides, Alkalinity and the Total Hardness, while Nitroge...

Effect of a Mixture of Allium Cepa and Camellia Sinensis Extracts On Hyperlipidemia Male Wistar Rats

ABSTRACT The burden of hyperlipidemia is on the rise globally especially in many low income countries like Uganda. Management of this metabolic disorder mainly involves dietary and behavioral therapies, which are often met with poor results as they require time and discipline from the patients. The chemotherapeutic options available are expensive, are associated with many side effects and are not readily available to the average citizen. Thus, an alternative effective remedy which is readily ...

Effect of a Mixture of Allium Cepa and Camellia Sinensis Extracts On Hyperlipidemic Male Wistar Rats

ABSTRACT The burden of hyperlipidemia is on the rise globally especially in many low income countries like Uganda. Management of this metabolic disorder mainly involves dietary and behavioral therapies, which are often met with poor results as they require time and discipline from the patients. The chemotherapeutic options available are expensive, are associated with many side effects and are not readily available to the average citizen. Thus, an alternative effective remedy which is readily ...

Population Growth and Youth Unemployment in Uganda (1991-2014)

ABSTRACT This study was motivated by the fact the Uganda has one of the fastest population growth rates in the world accompanied by high unemployment rates thus the study aimed at investigating the relationship between population growth rates and youth unemployment in Uganda (1991 to 2014). The specific objectives of the study were; to find out the long run relationship between the population growth rate and youth unemployment rate in Uganda, to examine the causality between population growth...

APPLICATION OF POLLUTION INDICES FOR THE ASSESSMENT OF HEAVY METALS POLLUTION IN SOILS AROUND ABANDONED ONYEAMA COAL MINE, SOUTHEASTERN, NIGERIA

The primary aim of this study is to indicate the seasonal variations of heavy metals in the soil within the Abandoned Onyeama Coal Mine. To examine the extent of heavy metals pollution, 45 soil samples were collected from different locations inside and outside Abandoned Onyeama Coal Mine during the rainy and dry seasons for one year. The level of toxic metals viz., Pb, Cu, Mn, Zn, Cd, Fe and Cr were analyzed using atomic absorption spectrophotometer. Majority of the samples were below the sta...

Effect of sintering additives on the densification and dielectric properties of Sr0.5Ba0.5Nb2O6 ceramics synthesized by a soft-chemistry method

https://doi.org/10.1016/j.jssc.2022.123564._ Nano-crystalline Sr0.5Ba0.5Nb2O6 powders with addition of LiNbO3 or LiF as sintering additives were prepared by a soft-chemistry synthesis using polyethylene glycol. Calcination at 600 C results in nanocrystalline powders (dcryst. 30 nm) which were sintered between 1000 and 1300 C to ceramic bodies. By addition of 10 and 20 mol % LiNbO3, the sintering temperature was reduced by about 200 K and the activation energy of the initial stage of sintering...

Determining Global Solar Radiation Incident on Tilted Surfaces with Different Tilt Angles at the Department Of Physics Makerere University

ABSTRACT Solar radiation data at horizontal level, tilted surfaces and in the atmosphere is an important feature in solar energy applications such as photovoltaic systems for electricity generation, solar collectors for heating and passive solar devices. This study presents an investigation of the dependence of global solar radiation incident on a tilted surface on some meteorological parameters for different tilt angles based on measured meteorological data of sunshine, relative humidity and...
