Hydrocarbon Degradation in Caspian Sea Sediment Cores Subjected to Simulated Petroleum Seepage in a Newly Designed Sediment-Oil-Flow-Through System

The microbial community response to petroleum seepage was investigated in a whole round sediment core (16 cm length) collected nearby natural hydrocarbon seepage structures in the Caspian Sea, using a newly developed Sediment-Oil-Flow-Through (SOFT) system. Distinct redox zones established and migrated vertically in the core during the 190 days-long simulated petroleum seepage. Methanogenic pet...

Microbial Community Response to Simulated Petroleum Seepage in Caspian Sea Sediments

Anaerobic microbial hydrocarbon degradation is a major biogeochemical process at marine seeps. Here we studied the response of the microbial community to petroleum seepage simulated for 190 days in a sediment core from the Caspian Sea using a sediment-oil-flow-through (SOFT) system. Untreated (without simulated petroleum seepage) and SOFT sediment microbial communities shared 43% bacterial genu...

Estimation of Friction Coefficient in Sediment Contained Flow through Rockfill

An increase in the flow velocity in flowthrough large porous media and deflection of flow regime from Darcy law causes a nonlinear relationship between hydraulic gradient and pore velocity of media. So many investigations have done previously in such Medias. One of the most important subjects in flowthrough large porous media is relationship between friction coefficient and flow characteristics...

Quantitative analysis of urine sediment using newly designed centrifuge tubes.

We quantified the formed elements of urine sediment using newly designed plastic centrifuge tubes with top and bottom openings and a 0.5 ml sized bottom ball (YZ tube). This design minimizes the adherence of formed elements that occurs on the glass surface of conventional tubes. The numbers of white blood cells (WBC) and red blood cells (RBC) using glass tubes did not differ from those observed...
