Abstract —The use of Information and Communication Technologies (ICTs) in teaching and learning has brought new teaching and learning experience to both teachers and students in many countries. Tanzania has made several efforts to achieve this but little has been done to determine the readiness of our schools and teachers in terms of ICT infrastructure and possession of other gadgets to help in the integration of ICT in education. This study aimed at looking into the readiness of Secondary ...
ABSTRACT Student Information Management System (SIMS) provides a simple interface for maintenance of student information. It can be used by educational institutes or colleges to maintain the records of students easily. A number of problems associated with student academic record management include improper course registration, late release of students' results, inaccuracy due to manual and tedious calculation and retrieval difficulties/inefficiency. In most cases the data generated by ac...
ABSTRACT The continuous advances in today’s digital universe and integration of computing into virtually every facet of human life are no doubt making the concept of Big Data a ubiquitous paradigm for deploying novel technologies/applications hitherto not practicable by conventional methods. Big Data, a general term for the massive amount of digital data being generated from different sources, extremely large, structured/unstructured too complex for analysis through conventional relational...
The main goal of this study is to extract natural flavour from mint and orange peels by distillation production in sudan and its utilization in improving the biscuit product flavour. The flavours were extracted by steam and water distillation. It was conducted to determine the physico chemical propereties of flavour and it’ s effect on different added levels (1,2,and 3 ml) on the sensory evaluation of the final product. The proximate analysis for both flavoured biscuits ,with orange ...
ABSTRACT Student and computer interaction becomes more salient where visual-auditory hardware and materials are required in classroom environment which are used for formal education. For instance, as a substitute of having classes during sessions, students learn mostly outside the class, by reading, watching videos and listening to podcasts or other audio format. Adaptive flipped classroom model is a learning and teaching approach that inverts the traditional classroom, in other words activi...
ABSTRACT Malaria is one of the world’s most common and serious diseases causing death up to about three million people each year. Its most severe occurrence is caused by the protozoan Plasmodium falciparum. Reports have shown that the resistance of the parasite to existing drugs is increasing. Therefore, there is a huge and urgent need to discover and validate new drug or vaccine targets to enable the development of new treatments for malaria. The ability to discover these drug or vaccine ...
Sonchus oleraceus (moleita) from the family Asteracae was investigated for its radical scavenging activity. The whole herb was firstly extracted with dicloromethane to remove as much of chlorophyll and other colouring pigments. The plant residue was extracted with methanol. The methanol extract was tested for its antioxidative contents. The methanolic extract showed 88% radical scavenging activity against DPPH(1,1-Diphenyl-2-picyl hydrazyl) a reagent used to test compound for their abil...
In this study 15 soil samples were collected from Dallanj town where dividing the town into five parts (E, C, S, N and W) using GPS .Three samples were taken from each part. 500 grams of soil sample was weighed and closed in plastic containers for four weeks so as to have secular equilibrium for uranium. Our goal of this study was estimate Investigation of Radionuclides Soil Samples from South of Kordufan state (Western Sudan). Natural radioactivity concentrations in soil samples were m...
Viral hepatitis is an inflammation of the liver due to viral infections and there are groups of viruses that affect the liver of which hepatitis B and C viruses are the causative agents of sever form of liver disease with high rate of mortality. Laboratory waste handlers who undergo collection, transportation, and disposal of laboratory wastes in the National laboratory for public health are at risk of exposure to acquire those infections which transmit mainly as a result of contaminate...
Diabetes Mellitus result from insufficiency of insulin secretion or concomitant resistance to the metabolic action of insulin on target tissue, then hyperglycemia as developed. Alpha amylase is enzyme which hydrolyses starch molecules to give smaller polymers composed of glucose unit which cause increase blood glucose. Therefore analytical, case control and hospital base study conduct in Ahmed Qasum hospital in Bahri in Khartoum state (Sudan) during the period from March to Jun 2015 toc...
Abstract Malaria is one of the planet's deadliest diseases and one of the leading causes of sickness and death in the developing world. Africa has suffered and is still suffering from the adverse socio-economic effects of malaria; It is intimately connected with poverty. Judged as both a root cause and a consequence of poverty, it is most intractable for the poorest countries in the world. According to GSK’s (GlaxoSmithKline) Corporate Responsibility Report 2007, it affects the health and...
ABSTRACT This chapter provides solutions for increasing the efficiency of data transfer in modern computer network applications and computing network environments based on the TCP/IP protocol suite. In this work, an imitation model and simulation was used as the basic method in the research. A simulation model was developed for designing and analyzing the computer networks based on TCP/IP protocols suite which fully allows the exact features in realizing the protocols and their impact on inc...
Abstract This work takes a look at different computational algorithms used in solving initial value problems and how these algorithms arc derived from Taylor's series. It also made use of the Euler and Runge-Kutta method to solve initial value problems in order to compare the performance of the two methods.
ABSTRACT This study involved the isolation, purification and characterisation of the bioactive phytochemicals from the ethanolic extract of young twigs and leaves of C. bonduc, the determination of the antimalarial activity of each isolated phytochemical, and the investigation of their in vivo toxicological effects. Further extractions were carried out using petroleum ether, ethyl acetate, butanol and water. Bioassay-guided fractionations of petroleum ether and ethyl acetate fractions were c...
