ABSTRACT Cashless economy has ushered in the cashless banking framework across different countries of the world and this is made possible by the advances in information technology. Electronic cash is a term becoming more acceptable as the world makes a shift towards a cashless society. This research work presents the development of a mobile payment system which implements cashless economy. The main aim of this development is to reduce some cash-related crimes in our society such as: robberie...
ABSTRACT The roots of Dennettia tripetala and Milicia excelsa were analyzed for the presence of phytochemicals. Five different solvents, which include methanol, ethanol, ethyl acetate, butanol and water, were used for the extraction of the phytochemicals.The root of Dennettia tripetala contained alkaloids, terpenoids, flavonoids, saponins, phenols, steroids and glycosides in varying degrees of abundance in the different solvents with tannins not detected in all the solvents. Milicia excelsa...
ABSTRACT. Waste disposal and groundwater quality studies were carried out in the Jimeta- Yola area. The area lies between latitudes 9'1 1'N to 9'20'~a nd longitudes 12'23'~t o 12'33'~a~nd covers an areal extent of about 305km2. Groundwater quality monitoring was carried out through the collection of water samples from hand-dug wells, boreholes and leachates beneath refuse dumps. These samples were analyzed chemically and bacteriologically using atomic absorption spectrophotometer (AAS), DW201...
ABSTRACT Tandem amidation catalyzed synthesis of linear diazaphenoxazine carboxamide derivatives is reported. This was achieved by the reaction of 2-amino-3-hydroxypyridine and 2,3,5-trichloropyridine in aqueous basic medium which gave 3-chloro-1,9-diazaphenoxazine as white solid crystals. 3-Chloro-1,9-diazaphenoxazine was then subjected to Buchwald-Hartwig amidation coupling reaction with various amides namely formamide, phthalamide, 4- nitrobenzamide, benzamide and acetamide via water prom...
Abstract A systematic approach for assessing critical performance indicators can be achieved through the implementation of a quality assurance (QA) program. The objective of this study was to evaluate the quality control of x-ray mammography machine in two centers, namely: during the period from October to December 2017. The test results were done by quality control tools and image quality tools. Series of tests(specific radiation output, output variation with kVp, output variation with mAs,...
Abstract Project Based Learning (PBL) is about giving students a real projects and asking them to come up with solutions to it as an academic task. Studies pointed out some problems associated to PBL approach, such as social loafing, that is when some students hide themselves behind active students, doing less or no works within the team and put the effort on other team members. Another problem is unfair assessment which result in giving all the students the same marks in spite of their effor...

ABSTRACT An integrated geological, geoelectrical and hydrogeochemical investigations were carried out in Eha-amufu to determine the extent and the distribution of saline zone. Hydrochemical characteristic of the groundwater in Eha-amufu was investigated. Eha-amufu area is underlain by Nkporo Formation and Awgu Formation. Both are of low permeability Formation. Twenty seven (27) Vertical Electrical Sounding (VES) were occupied at different locations within the study area, employing the Schl...
Abstract Currently climate change represents the focus attention of the global world and how to reducing greenhouse gas emission, which led to use other energy source, especially renewable energy source, Tidal power it is a renewable and clean source of energy, can represent a solution of the many environmental pollutants resulting from use another energy source, besides this source exposed to exhaustible as a result of intensive use. Tidal power is unconventional sources of energy which is ...
Abstract Back ground: Glucose is key to keeping the mechanisms of the body in top working order. Along with fats, glucose is one of the body's preferred sources of fuel. Glucose levels that are unhealthy or out of control can have permanent and serious effects. Objective: To measure blood glucose level storage in different anticoagulants at room temperature. Methodology: The study was conducted in Khartoum state from the period of March to September 2020. Including 60 healthy volunteers age ...
ABSTRACT Ximenia Americana is considered one of medicinal plant which are widely used especially in West of Sudan. This plant has been studied in this research, which is collected from Nuba Mountains and Babanusa. In part I of the present study, crude extracts of different parts of plant was investigated for their biological activity. Preliminary investigations were carried out to select the plant extracts of the highest activity for further investigation. The extracts were screened for phyt...
Abstract Diagnosing cardiac diseases by using an advanced statistical classifying model is vitally important for cardiac diseases which are viewed as serious diseases which can put an end to a patient’s life, therefore, early diagnosis should be done through classification and to differentiate among the cardiac patients and non-cardiac ones based on the factors that can cause the cardiac diseases by using technologies such as logistic regression and discriminative analysis. This study aime...
ABSTRACT Despite the successes of commercial cloud service e-marketplaces, opportunities still exist to improve user experience as these e-marketplaces do not yet enable dynamic composition of atomic services to satisfy complex user requirements. More so, the platforms employ keyword-based search mechanisms that only allow the selection of atomic services. The elicitation mechanisms do not consider user’s QoS requirements, nor support the elicitation of these requirements in ways akin to s...
ABSTRACT Mathematical models describing the variations in the plasma glucose and insulin levels over time in an insulin - dependent diabetic person (IDD patient) were formulated. We showed that these models can correctly describe these variations when we solved them sirnuttaneously by andytical approach rather than the normal numerical approach employed for solving non-linear differential equations. The effect of the various parameters involved in the model were tested and it was shown ...
