This study experimentally investigates the effect of multi-walled carbon nanotubes (MWNT’s), as a reinforcing material, on the physical properties of heavy-weight oil well cements. A candidate well is selected and the properties of the cement slurry used in a problematic section of the well are tested in the laboratory. Carbon nanotubes (CNT’s) are added as fibers to the cement slurry and the i...

  SUMMARY Otitis media with effusion is disease of children that accumulate steril fluid in the middle ear. Chronic form of disease called when the fluid remained for 12 weeks in the middle ear, that is, important cause of mild hearing loss in the school age and behavior disorder and difficult in the learning. In this study 71 patients that admitted and treated with surgical (Adenoidectomy a...

Rapid fluid administration is often required for resuscitation when patients are admitted in emergency department with hypovolemic shock or excessive blood loss. Various methods have been described earlier to increase the fluid administration speed. Larger vein size, larger bore cannula, height of fluid, pressure over fluid bottle etc. are some of methods described in such situations.We here de...

We show that the fluid loss ratio in a fluid queue with finite buffer and constant link capacity is always a jointly convex function of and . This generalizes prior work [6] which shows convexity of the trade-off for large number of i.i.d. multiplexed sources, using the large deviations rate function as approximation for fluid loss. Our approach also leads to a simpler proof of the prior result...

PURPOSE To evaluate the effect of power, vacuum, and flow rate on endothelial cell loss after phacoemulsification. SETTING Labbafinejad Medical Center Medical Center, Tehran, Iran. METHODS In a prospective randomized clinical trial, phacoemulsification was performed in 2 groups (high vacuum and low vacuum) with 3+ nuclear sclerosis. The stop-and-chop technique was used with the Sovereign ma...

This study measured fluid balance during a 90-min preseason training session in the first team squad (24 players) of an English Premier League football team. Sweat loss was assessed from changes in body mass after correction for ingested fluids and urine passed. Sweat composition was measured by collection from patches attached to the skin at 4 sites. The weather was warm (24-29 degrees C), wit...

Lumbar epidural analgesia is frequently employed to provide pain relief for women during labor. Anesthesia providers use various methods to identify the epidural space. Some providers use air, some use fluid, and others use a combination of air and fluid during the loss of resistance technique. Loss of resistance to air has been speculated to result in a lesser quality of analgesia compared wit...
