ABSTRACT Ebola Virus Disease (EVD) and Lassa fever are infectious viral diseases that are very deadly to mankind. These diseases, when handled lightly can quickly degenerate into deadly epidemics. Accurate and prompt diagnosis, and effective treatment of these infectious diseases is a very critical factor in their prevention and containment. The difficulty in differentiating between EVD and Lassa fever at their initial phase can result in wrong diagnosis which can be catastrophic. An intellig...
ABSTRACT The study examined women's autonomy by fertility behaviour in northern Nigeria using Nigeria Demographic and Health Survey women recode dataset. Analyses were done at three levels, univariate level by means of frequency distribution, bivariate level by using Chi-square test and multivariate level by the use of multinomial logistic regression models. Findings revealed that 7.1 % of women enjoyed autonomy. In all, 63. 7% of women were working and there was a significance relationship ...
Abstract In this work magnesium chromate (MgCr2O4) samples were produced by combustion method. Sample 1 was prepared without adding ammonia hydroxide (pH = 0.96) during synthesis steps whilst sample 2 was prepared with ammonia hydroxide (pH = 8.62). Sample 1 was obtained in 2:10 h whilst sample 2 was produced in 45 min. Effect of pH upon structural properties were investigated by X-rays diffraction (XRD) technique. The results confirm the formation of the cubic spinel structure with average ...
ABSTRACT This study was conducted to evaluate the effect of black cumin (Nigella sativa L.) seeds oil (BCSO) on crude and refined peanut oil stability during frying periods. Crude and refined peanut oil was blended with 5%, 10% and 15% BCSO and commercial antioxidant (CA). The blends were used to fry potato chips for up to 60 min. Black cumin seeds collected from the local market, were analyzed for protein, moisture, fats, fibers and carbohydrates contents then physical properties (colour, r...

Abstract This study focuses on determine of the percent of carboxymethyl cellulose in ice-cream stabilizer which has been used under the number E466 it was determined to be 98.92%. First the percent of sodium chloride determined by Volhard method it was found to be 0.48% then freeflycolate were determined by U.V spectroscopic method the percent was found to be 0.59%. Finally the degree of substitution Ds were determined gravimetrically it was found 0.2. FT-IR spectroscopy also were used to ...
Abstract Nondestructive testing methods are that used widely in industry and technology so to test material and equipment to make sure that they are proper and secure. In this work three samples from steel, carbon steel and aluminum were subjected to same fraction force. The damages produced were tested by ultrasound and magnetic particles. The fraction length obtained by magnetic particle and ultrasound give the same result. Where the length in the aluminum, steel and carbon steel defects ar...
Abstract This study was conducted to treat the Sudanese crude oil from Rawat area southwest of Kosti which has a high wax content of 26.3% by weight and pour point 54°C, in order to remove the wax and to reduce the pour point and enhance the physical and molecular properties of the treated oil using organic solvent de-waxing technology. The physical and molecular properties of crude oil and the oils produced from the treatments were obtained using American Society for Testing and Materials ...
Abstract The objective ofthis study is to characterize and analyse threedifferent samples of polypropylene of which one was collected from Elkherat Factory (Omdurman) and two from Khartoum Petrochemical Company .The flame test of these three samples, gave a blue – yellow colour. The results of melt flow rateof these sampleswere 2.63g/20 min , 2.71gminand 2.99g/20 min, respecvely.The results of melting point were 149 ◌C, 152 ◌c and- 160 ◌c. The results of bulk density were 0...
ABSTRACT Cross-language information retrieval (CLIR), where queries and documents are in different languages, become one of the major topics within the information retrieval community. The important step in CLIR is the translation. This research proposes a term translation disambiguation method based on co-occurrence statistics for translation in Arabic-English CLIR. There are multiple ways to perform query translations: employing machine translation techniques, using parallel corpora or usi...
Abstract This is a case-control study, conducted to determine the effect of cigarettes smoking on urea, creatinine and uric acid levels in Sudanese male cigarette smokers in a period from March to May 2015. Eighty samples were collected from cigarette smokers without diseases that may affect levels of urea, creatinine and uric acid. And fifty nonsmokers people as control were informed about study and informed consent for participation was obtained. 2.5 ml of venous blood was collected ...
ABSTRACT The spatial and temporal variations of fine particulate matter bound trace metals were investigated in three industrial estates namely Ota Industrial Estate (OTE), Ewekoro Community (EWC) and Agbara Industrial Estate (AGE) and one background (Covenant University Farm Ota) in Ogun State. The sampling period was six (6) months covering the wet and dry seasons. One hundred and fifty (150) samples were collected according to standard methods using environtech gravimetric sampler, a...
ABSTRACT This study tackles two concerns of developers of Tourism Information Systems (TIS). First is the need for more dependable recommendation services due to the intangible nature of the tourism product where it is impossible for customers to physically evaluate the services on offer prior to practical experience. Second is the need to manage dynamic user requirements in tourism due to the advent of new technologies such as the semantic web and mobile computing such that etourism systems...
ABSTRACT The University Course Timetabling Problem (UCTP) is a combinatorial optimization problem which involves the placement of events into timeslots and assignment of venues to these events. Different institutions have their peculiar problems; therefore there is a need to get an adequate knowledge of the problem especially in the area of constraints before applying an efficient method that will get a feasible solution in a reasonable amount of time. Several methods have been applied to s...
