A combined laboratory and numerical investigation of the purging of density stabilized basins has been undertaken. The laboratory investigation was carried out in a flume into which a false floor containing a cavity filled with dense fluid was set. The fluid in the cavity was then set into motion and ultimately purged by a fresh water overflow. The experiment was simulated numerically by a dire...

Tissue renewal is a well-known phenomenon by which old and dying-off cells of various tissues of the body are replaced by progeny of local or circulating stem cells (SCs). An interesting question is whether donor SCs are capable to prolong the lifespan of an aging organism by tissue renewal. In this work, we investigated the possible use of bone marrow (BM) SC for lifespan extension. To this pu...

The purpose of this study was to evaluate the photosensitizing dye merocyanine 540 (MC540) as a means for extracorporeal purging of Plasmodium falciparum-infected erythrocytes from human blood. Parasitized red blood cells bound more dye than nonparasitized cells, and exposure to MC540 and light under conditions that are relatively well tolerated by normal erythrocytes and normal pluripotent hem...

Diverticular disease is the most frequent cause of lower gastrointestinal bleeding. Most of the times, bleeding stops without any intervention but in 10-20% of the cases it is necessary to treat the hemorrhage. Several modalities of endoscopic treatment have been described after purging the colon. We present five cases of severe diverticular bleeding treated with injection of epinephrine and he...

During the trial production of marine gas hydrate in former Soviet Union, Canada, North Slope Alaska, South Sea Trough Japan and Shenhu China Sea, problem sand water cannot be avoided. The problems process natural depressurization exploitation have seriously restricted efficiency hydrate. are some main factors that prevent being commercially exploited. Therefore, it is urgent to carry out usefu...

A control oriented dynamic model of the Lean NOx Trap (LNT) behavior has been developed in SIMULINK. The model simulates the trapping and purging phenomena and includes the important parameters which affect the LNT behavior. These include the trap temperature, trapping and purging duration, air fuel ratios and the mass flow rates of the exhaust gases. Engine dynamometer test data have been used...
