Hydrogen sulfide is one of the main waste products petrochemical industry; it produced by catalytic hydrodesulfurization processes (HDS) hydrocarbon feedstocks, and a byproduct from sweetening sour natural gas upgrading heavy oils, bitumen, coals [...]
This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...
Recognition of heavy minerals in Oman continental shelf sediments and their application for interpretation of sediments sourc rock is the purpose of this study. Seven core samples of sea sediment and three surface samples from tidal flat area have been examined. Heavy minerals are dense grains, wich are found not only in rocks, but also in different types of sand and sediments. Separation of he...
Hille DM, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-223003 Description This report of a mass in the upper eyelid resulting from long-term complications of heavy liquid tamponade therapy of retinal detachment is a good example of learning from rare cases. Retinal detachments may be repaired by scleral buckling, vitrectomy surgery or by a combination of both techniques. Retinal detachments r...
The task of CO2 decomposition is one the components problem associated with global warming. One promising directions its solution use low-temperature plasma. For these purposes, different types discharges are used. Microwave discharge in liquid hydrocarbons has not been studied before for this problem. This paper presents results a study microwave products Nefras C2 80/120 (petroleum solvent, m...
