ABSTRACT The antibiotic susceptibility pattern of aerobic mesophilic bacteria isolated from kunu samples sold in Ile-lfe, Osun State, Nigeria was studied following standard microbiological methods. Seven ready-to-drink kunu samples were purchased from different hawkers at Ile Ife. The samples were transported immediately in ice bucket to the laboratory for analysis. The aerobic mesophilic bacteria associated with kunu samples were isolated, labeled and identified by phenotypic and biochemica...
Abstract In this research we studied Fourier transform and Fourier Analysis. We first introduced an analytical formulation using Hilbert space. We utilized the principle of uniform boundedness and the open mapping theorem to establish the convergence of Fourier series and the existence of Fourier transform. Here the geometry of Hilbert space has been involved. Then we applied Fourier transform to Engineering problems, these include Motion group, Robotics, Statistical mechanics, Mass de...

Abstract This study was aimed to assessment of grid alignment for radiology departments in Khartoum state. A total of 15 x-ray units in radiology departments in Khartoum state were tested by grid alignment test tool and the optical density for radiographic film was read by transition densitometer. In this study the final result showed that the percentage of grid misalignment for x-ray machines (66.7%) greater than the grid alignment x-ray machines (33.3%). The final assessment of grid misali...

This study performed in Modern Medical Center , the study showed amount of average effective dose (1.26756002 mSv ± 0.2 mSv ) and it's n...
ABSTRACT The main goal of this study was to develop aready-to-serve gluten free vegetables based infant food product with high nutritional value, high physicochemical, microbial and organoleptic characteristics in order to contribute in solving the problem of children malnutrition in Sudan. The results obtained in this study indicated that the developed vegetables based infant food product was found with high levels of available carbohydrates (68.32%), total sugars (12.75%) and protein (6.7%...
Abstract Some of the mechanical properties of polymer, such as tensile test, creep and swelling, were studied for two types of tire rubber at different concentrations of black carbon(70% ,30%) respectively. In the tensile test, the elasticity modulus was calculated and found that it was 7.836 MN/m2. Also in the study of creep, the time-dependent creep modulus and the creep compliance were calculated. Then the swelling behavior was introduced using three chemical solutions, namely methane, ace...
Abstract 57Fe Mössbauer spectroscopy is one of the most powerful tools that used in studying magnetic properties of materials. This work aims to investigate the magnetic properties of MgxSrxMnxCo1-3xFe2O4 (x = 0, 0.1, 0.2, 0.3 and 0.33) nanoparticles annealed at 500 ˚C. The aim extends to study the magnetic properties of BaFe2O4 sample as a function of different measuring temperatures. The results showed that magnetic hyperfine fields of the annealed samples were larger compared to as-prep...
Abstract This study was carried out to estimate acrylamide content in some Sudanese foods including Rugag (thin sheets of baked wheat flour), homemade biscuit with ammonium bicarbonate and homemade biscuit without ammonium bicarbonate. Rugag was prepared according to the traditional method employed in Sudanese house hold. Prepared from 72% extraction wheat flour, sugar, milk powder, vanilla, corn flour, salt, and baking powder, baked in thin sheet on hot steel plate at 170 ˚C for 40 seconds...
Abstract Phytochemical screening of the stem bark of Zingiber officiale revealed the presence of tannins,flavonoids and alkaloids. The bark of this species was macerated with 95% ethanol. A silica gel column developed with chloroform:methanol(3:2;v:v) gave apure flavonoid compound I. The structure of this isolate was elucidated using UV and IR data and The following partial structure was proposed:
Abstract A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. In this thesis three types of thin films of silicon dioxide were prepared then doped using three different samples Iodine, Coumarin500 and Rhodamine B. The preparation was done under Electrical Deposition Techniques (E D T) (Spin Coating) using power supply mating 2 Volts and current of 0.03A, at room temperature. The optical properties such as absorption and abs...
Abstracts: The mammography is examination of x – ray to early detection of the breast cancer. However the delectability of micro calcifications is required high quality image. Thus evaluation of image quality is important. The main objective of this study was to evaluate image quality for full field digital mammography at omer sawey hospital Khartoum state - Sudan. The tests that were performed in this study include: Contrast to noise ratio and spatial resolution. Contrast to noise ratio wa...
ABSTRACT The main objective of this study was to assess patient dose during x-ray examination of skull and thoraco-lumbar in Red Sea state Hospitals. The dose received by 146 adult patients was measured using CALDOSE software by entering the parameters: focus to detector distance FDD, mAs , KVP. The result of the study showed that the mean of ESAK were found to be (0.79 ± 0.30) for skull and (0.37 ± 0.2) for thoraco-lumbar. The INAK were found to be (0.52 ± 0.14) for thoracic lumbar and (...
ABSTRACT A field experiment and quality was conducted on a silty loam soil located at Demonstration Farm of the College of Agricultural Studies, Sudan University of Science and Technology at Shambat, Sudan, during two growing summer and winter seasons of 2011/2012 to study the effect of bio-fertilizers on growth, yield of two hybrids of sunflower. The effect of bio-fertilizers on the soil were also determined. The bio-fertilizer levels were (Zero, 06.25, 12.5, 18.75 and 25.00 L/Ha) correspon...
Abstract Space weather has been a task of research in modern fields of science; therefore, our recent technology is certainly influenced by impact of space weather particularly in satellites, spaceborne systems. Moreover, space weather has impacts on ground based technology such as electric power system, pipeline, and railways. Space weather variations can cause geomagnetically induced currents penetrate conducting structures of the transformers and cause: half-cycle saturation, increase the ...
