This study is done to investigate the quality of water in Sodri in North of Kordfan and to see the effect of traditional mining on it’ s quality. Three samples of groundwater were collected according to standards methods:- One sample from the hafir and two samples from the wells. Samples were analyzed for physical and chemical parameters. A number of analytical techniques were used. Atomic Absorption Spectroscopy was used for quantification of elements namely iron, zinc, manganese an...
Abstract The environmental impact of traditional Gold mining activity has become a concern. The concern is due to the methods that are used in the extraction of the Gold from its co-metals, particularly the use of the Mercury. The purpose of the study to identify the impact of the traditional gold mining in Elcrow in Abo Hamad district. This research was undertaken to determine the concentration of toxic heavy metals that have been used to extract gold such as Mercury or has been released du...
Samples of Anogeissus leiocarpus gum were randomly collected as natural exudates from different locations of the Sudan gum belt. The physicochemical properties of composite samples studied were moisture content, ash, nitrogen, protein, specific rotation, relative viscosity, refractive index, density, also UV electromagnetic radiation, metals ions, pH, uronic acid, reducing sugars and infrared spectra. Analysis of variant of results showed insignificant dif ferences (p < 0.05) in all pro...
At the present work a simple, precise, accurate and economical reverse phase HPLC with UV detector method, was developed and validated for the simultaneous determination of acetaminophen and orphenadrine citrate in pharmaceutical formulations. better separation was achieved using cyanide column (250mm × 4.6mm, 5μm), maintained at 25 ͦC. The mobile phase was composed of (tri ethyl amine aqueous, methanol and acetonitrile) in the ratio of 50:20:30 (v/v/v), adjusted at pH 3.8 by ortho ...
Abstract In this research two types of activated carbon (AC) were prepared from Sudanese Nabag shells. The first one of AC was prepared by pregnating the shells with sulphuric acid before carbonization. The second type of AC was prepared without chemical treatment. The percentage yield of the products were calculated and found to be 32.31% for the AC treated with acid and 24.88 % for AC prepared without chemical treatment. The functional groups for the two carbons were determined by FT-IR te...
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...
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 This study aimed at developing agar extraction protocol from local Gracilaria salicornia species and investigates its physico-chemical characteristics, production cost and application in tissue culture of Pleurotus HK-37. Purposive sampling was used in collection of Gracilaria salicornia during dry (northeast monsoon) period in 2016 at Chwaka bay, Zanzibar, Tanzania. A 33 factorial experimental design was used in the extraction of treated agar whereby three independent variables of ...
ABSTRACT This research work presents the optimization of the reaction parameters for the productions of HMF from Tanzanian sugarcane bagasse under pressurized conditions using high pressure reactor. The sugarcane bagasse (25 g) was hydrolyzed at different temperatures, different concentrations of the hydrolyzing acid, and different reaction time. A total of 27 hydrolysis experiments were carried out in a non-stirred SS-304 pressure reactor. The sugarcane bagasse was hydrolyzed using sulphuri...

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...
