In thermally enhanced recovery processes like cyclic steam stimulation (CSS) or steam assisted gravity drainage (SAGD), continuous steam injection entails changes in pore fluid, pore pressure and temperature in the rock reservoir, that are most often unconsolidated or weakly consolidated sandstones. This in turn increases or decreases the effective stresses and changes the elastic properties of...

Cryotherapy is a common treatment modality after orthopedic surgery procedures. Single institutional randomized clinical trials have evaluated the efficacy of cryotherapy after arthroscopically-assisted anterior cruciate ligament (ACL) reconstruction. Most of these studies were, however, underpowered to detect clinically relevant outcomes differences. This meta-analysis assessed the combined sc...

We report the results of our experience using video-assisted thoracoscopic surgery (VATS) to treat primary spontaneous pneumothorax (PSP) from January 1992 until December 1994 in a multicentered co-operative study. A total of 132 patients (110 males and 22 females, aged 13-38 yrs, mean age 26 yrs) were treated by VATS to deal with the PSP that they presented with. A standard VATS technique was ...

Abstract Background The optimal type of operative drainage following pancreaticoduodenectomy (PD) remains unclear. Our objective is to investigate risk associated with closed techniques (passive [gravity] vs. suction) after PD. Methods We assessed utilized in patients undergoing PD the ACS-NSQIP pancreas-targeted database from 2016 2018. Using multivariable logistic regression adjust for charac...

SAGD (Steam Assisted Gravity Drainage) is used in Canadian fields where there are interlayers that impede steam chamber development and thus production. Many experiments have been conducted on the effect of oil recovery. However, swelling characteristics under different conditions, as well possible clay mineral transformation particle migration particles at high temperatures, rarely studied. In...

BACKGROUND Pulmonary visceral subpleural hematoma is rare. We report visceral subpleural hematoma of the left diaphragmatic surface following left upper division segmentectomy. This very rare case was difficult to distinguish from thoracic abscess. CASE PRESENTATION A 68-year-old man with hypertension had undergone video-assisted thoracoscopic left upper division segmentectomy for suspected l...
