Study of Oil from Seeds of (Adansoniadigitata) by GC-M.S

Phytochemical investigation of fruit pulp of Adansonia digitata gave positive reactions for : steroids,terpenes,flavonoids,tannins and glycosides. GC-MS analysis of Adansonia digitataoil was conducted and the identification of the constituents was initially accomplished by comparison with the MS library (NIST) and further confirmed by interpreting of the observed fragmentation pattern.Comparison of the mass spectra with the database on MS library revealed about 90-95% match. The GC-M...

Biochemical Analysis of Synovial Fluid and Serum in Sudanese Cattle

This study was conducted to establish reference values for some biochemical parameters of synovial fluid in Sudanese cattle and to compare them with the corresponding values in serum, also to establish the correlation and regression among serum and synovial fluid parameters. The bulls were selected from the herd of the Animal Production Research Centre- Khartoum North- Hilat kuku, from January 2018 to October 2019. Eleven blood samples and twenty two synovial fluid samples were collecte...

Primary Health Service Distribution in Urban Areas Using GIS

Dealt with the subject of the study through spatial distribution of the governmental health centers, for understanding its relationship with the numbersof population, health outcomes and access, in light of rapid urbanization  worldwide. The crisis in the health sector of Sudan has seen very obvious since the last decade, particularly in Bahri locality. It turns out the requires of appropriate infrastructure because of lack of attention to proper and suitable planning for the distribut...

Oral Candidiasis in Sudanese Cancer Patients Receiving Different of Treatments for different cancer types

This study was done to detect the prevalence of oral Candidiasis among Sudanese cancer patients with different cancer types who received different cancer treatment in Khartoumoncology hospital which formerly was known as Radio and Isotopes Centre of Khartoum (al Zarra Hospital) which recently named Khartoum Oncology Hospital. .A hundred oral swabs were collected from the patients with different age groups ranging from 2 to 83 old, 66@ were males and 34@ were females.The study was carried ...

The formal solution of constrained mechanical system

In this work we discuss the scope of Lagrangian mechanics and constrained systems. We discuss the problem of central force two–bodies and its formal solution. Also we study the rotations and rigid bodies by using Euler’s equations, Lagrangian description and Legender transformations with some examples and applications.

Modeling QSAR, Docking and Grinding Preparation of Some 3.5 Pyrazoline Derivatives, Against AsPC-1 Human Pancreatic Cell Line and U251 Human Glioblastoma Cell Line

The QSAR model were successfully developed to calculate biological activity of 3, 5 di-substituted Pyrazoline derivatives as anticancer agents against AsPC-1 human pancreatic cell line and U251 human glioblastoma cell line, a good correlation models were obtained with R 2 =74.30% and R 2 =75.92% respectively, compounds (5-(4- bromophenyl)-3-(4-nitrophenyl)-4,5-dihydro-1H-pyrazole) and (N, N-dimethyl-4-[3- (4-nitrophenyl)-4,5-dihydro-1H-pyrazol-5-yl] aniline) were found to be the most�...

Evaluation Of Kenya Alpine Dairy Goat (Capra Aegagrus Hircus) Milk Yield, And Its Nutritional And Chemical Composition For Product Development, In Nyeri County

ABSTRACT In Kenya use of exotic dairy goats in breeding programmes for smallholder production systems has become popular, but information on the milk production and nutritional quality is scarce. This research project was done to investigate the milk yield and its nutritional composition of Kenya Alpine dairy goat, Capra aegagrus hircus, for value addition. The initial work constituted assessing the dairy goat feeding practices in the study areas of Mukurweini, Kieni East and Kieni West, whe...

Spectrophotometric Determination of Nitrite content in Cured Meats

The aim of this study was to determine of nitrite ions (NO-2) in some locally produced, processed meats samples. Twenty three samples were obtained from the local markets in Khartoum state. The cured meat samples include Sausages, Martidala, Beef berger, Basterma, Hot dogs and Frankfurters. Nitrite ions were extracted from the samples by hot water. Nitrite content for each sample extract was measured by Uv-Vis spectrophotometry. Three samples showed nil nitrite content. Twenty samples ...

Removal of Heavy Metals from Oil Fields Drilling Mud Wastewater Using Zeolite.

The aim of this research work was to study the potential capability of zeolites and kaolin to remove some, heavy, metals from drilling mud wastewater. Four samples were used, (three zeolites and one kaolin). Two natural zeolites(Stablite and Stellerite)  collected from Al Gadaref state (East Sudan), synthesizedzeolite from fly ash using sodium hydroxide under hydrothermal  conditions. Kaolin sample collected from Elmerkhiat mountain (North-East Omdurman Sudan). X-ray diffraction (XRD) w...

Impacts Of Spatial Extend And Site Location On Calibration Of Urban Growth Models

Abstract During the last decades, cities in sub-saharan Africa have undergone rapid urban growth due to increased population growth and high economic activities. This research explores the impacts of varying modelling settings including spatial extend and its location for the city of Nairobi using a cellular automata (CA) urban growth model (UGM). Our UGM used multi-temporal satellite-based data for classification of urban land-use of 1986, 2000 and 2010, road data, slope data and exclusion ...

Impact of Cooking and Additives on the Chemical and Microbiological Characteristics of Indomie Noodles

The main goal of this study was to determine the effect of cooking and added materials (spices and monosodium glutamate) on the chemical and microbial characteristics of two types of indomie noodles )chicken and vegetable flavoured( . The samples were the products of Sawabash factory (Soba industrial area). The samples were analyzed before and after the cooking at 100o C for 20 minutes. The obtained results of the chemical analysis of vegetable flavoured and chicken flavoured indomie ...

Characterization Of Zn/Au Back Contact To Lowdoped P-Inp

Abstract. The mechanism behind the formation of alloyed ohmic contacts to p-type InP doped in the 1016 cm-3 range has been investigated. Techniques used for - characterising the contacts include the scanning electron microscope (SEM), specific contact resistance measurements, x-ray diffractometry (XRD), energy dispersive x-ray analysis (EDAX) and Auger electron spectroscopy (AES). Both temperature and time of annealing were varied during the study. The results obtained using our annealing pr...

ABSTRACT The Maastrichian-Paleocene sediments in Yuli area me composed of the Gombe Sandstone and the Kerri-Kerri Formation. They cover 400 square kilometres have a thickness of more than 100 metres. Six stratigraphic sections were studied, representing the entire stratigraphic succession of the Gombe Sandstone in the Yuli area, The formation has a thickness of about 30 metres in the studied area. The Gombe Sandstone consists of folded beds of sandstone, siltstone and mudstone. The sandstone ...

Determination Of Total Petroleum Hydrocabon In Sediment From Qua Iboe River Estuary

ABSTRACT The petroleum hydrocarbon composition of sediments from Qua Iboe River Estuary, Ibeno, South-Eastern Nigeria, was studied to determine the levels of these hydrocarbons in the marine environment.
