Microbial communities in streambed sediments recovering from desiccation.
Climate change affects running waters not only by increasing temperatures but also by increasing discharge variability as more frequent and severe floods and more frequent and longer droughts occur, especially in upper reaches. Mediterranean streams are known to experience droughts, but Central European headwaters are also beginning to be affected. The development of bacterial communities (abun...
متن کاملSimultaneous Ash and Sulphur Removal from Bitumen Using Column Flotation Technique: Experiments, RSM Modeling and Optimization
An efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. The bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. The Box-Behnken Design (BBD) was employed to design the experiments, to ...
متن کاملComparative evaluation of a modified zinc sulfate flotation technique.
A modified zinc sulfate flotation technique using Formalinized fecal specimens (F-ZnSO4) was compared to the Formalin-ether (FE) concentration method for the laboratory diagnosis of intestinal parasites. Many laboratories have difficulty storing, using, and disposing of either and need a procedure for concentrating fecal specimens which does not require ether. Comparative data were obtained for...
متن کاملAsh and sulphur removal from bitumen using column flotation technique: Experimental and response surface methodology modeling
This study investigates removing ash and pyrite sulphur from bitumen by column flotation process. Central composite design (CCD) of response surface methodology (RSM) was applied for modeling and optimization of the percentage of ash and pyrite sulphur removal from bitumen. The effects of five parameters namely the amounts of collector and frother agents, particle size, wash water rate and feed...
