Molecular Dynamics simulations (MD) of a double walled carbon nanotube (DWNT) motor, consisting of two coaxial carbon nanotubes are performed, where the inner tube behaves as a ”shaft” and the outer one as a ”sleeve” [1]. Brenner potential [2] is used for the intratube interactions along with Nordlunds long range interaction term [3] to account for the intertube interactions. Unit positive and ...

IMPLICATIONS Two patients experienced partial upper airway obstruction while breathing spontaneously with the ProSeal laryngeal mask airway. This resulted in esophageal aspiration of air through the drain tube.

The purpose of this study was to make public our results using endoscopic microsurgery in herniated cervical discs. This technique allows us to avoid complications due to conventional exposure, as is the case in traditional approaches. This study was carried out from January 1991 to January 1998. One hundred and seventy-one patients should have undergone traditional surgery for 296 herniated ce...

Achalasia is a relatively rare medical condition that is classically not associated with obesity. The surgical treatment of a simultaneous occurrence of these two diseases requires careful consideration, and only a few reports can be found in the literature combining a Heller myotomy with gastric bypass, duodenal switch, or gastric banding. We report the case of a 69-year-old female patient wit...

A 47-year-old woman developed a large area of anastomotic dehiscence (●" Fig.1a) 3months after sleeve gastrectomy for obesity. A 15-cm fully covered self-expanding metal stent (SEMS) was deployed to cover the anastomotic leak, as a bridge to surgery. This was anchored to the esophageal wall byendosuture (●" Fig.1b). Thepatient presented again 6 weeks later with distal SEMSmigration through the ...

U.S. Army Engineer Waterways Experiment Station (WES) investigators have designed, fabricated, and demonstrated a cone penetrometer sensor for subsurface in situ field screening based on LIBS. The LIBS probe (patent pending) presented here is one of a suite of contaminant and geophysical probes developed by the WES Site Characterization and Analysis Penetrometer System (SCAPS) program. The LIBS...
