Bioethanol Production from Sorghum Grains

Abstract A biofuel is a fuel that produced through contemporary biological processes such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes. It can be derived directly from plants or indirectly from agriculture or industrial waste. Bioethanol is an alcohol made by fermentation, it is produced from sugar or starch crops such as corn, sugar cane or sweet sorghum. Biodiesel and ethanol can be used as fuel for vehicles in its pure form but it is usually u...

Structural and Optical Properties of ZnO Nano-Powder Synthesized by Combustion and Sol-gel Method

Abstract Nowadays, ZnO is considered as the most important chemical compounds due their distinctive properties owing to its wide band gab and large exciton binding energy. It is well known that the structural and the optical properties of ZnO differ by different methods of preparation. Therefore, in this work, ZnO power was prepared by two methods, namely sol-gel and combustion method with the aim of comparison. The obtained samples from both methods were investigated by many techniques for c...

A Design of an Econometric Model for Evaluating the Security in Cloud Computing Environment

ABSTRACT Cloud computing offers an innovative business model for all cloud enterprises to serve IT services with no need to have technical details. The extreme growth of cloud usage increases the probability of threats occurrence, which in turn leads to financial and other losses. So there is a need to use appropriate metrics to assess the failure cost among cloud stakeholders according to their different needs; we propose a measure called “Mean Failure Cost” (MFC) which quantifies the im...

Antimicrobial and Antioxidant Activity of Hibiscus sabdariffa (Roselle) against Selected Microorganisms

Introduction: Prevalence of resistant microbial strains is increasing with time; due to the extensive and indiscriminate use of the broad spectrum antimicrobial drugs that render the current used antimicrobial agents insufficient to control some microbial infections. Objective: The present study was aimed to investigate the antimicrobial and antioxidant potential of methanolic extract of the medicinal plant Hibiscus sabdariffa L. Method: The agar well diffusion technique was used to determin...

A Secure Centralised Web Based Criminal Data Base Management System Case Study: Central Police Station (Cps) Kampala

ABSTRACT The study was to access the role of electronic media in recording and updating criminals across the nation as a whole. Using Central Police Station as a case study, the objectives of the study were to provide ways how the Police could keep/store records of criminals across the country, to identify media programs that enable a police officer to record a criminal into a very secure database management system throughout the entire country. The research was carried out through both theor...

Determination of Gold Concentration in the Gold Ore in Lujinji, Mubende District.

Abstract 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...

Design, Development and Implementation of Court Management System for Uganda Courts

ABSTRACT Two major challenges in legal decision making arise from the high complexity of the cases and from the high level of uncertainty caused by incomplete or missing information. In most cases it is not possible to apply Bayesian probability and legal standards prohibit the application of fastand-frugal heuristics. Based on a connectionist approach to decision making, Simon (2004) argued that decision making in complex decisions is governed by coherence-based reasoning. The underlying par...

A Computerized Students' Records Management System A Case Study of Faculty of Science and Technology Kampala International University Western Campus
