Catalyst Deactivation Simulation Through Carbon Deposition in Carbon Dioxide Reforming over Ni/CaO-Al2O3 Catalyst [PDF]

, 2011
Major problem in CO2 reforming of methane (CORM) process is coke formation which is a carbonaceous residue that can physically cover active sites of a catalyst surface and leads to catalyst deactivation.

Laparoscopic ultrasound eXAmination: Analysis of fellow surgeons learning curve in minimally invasive gynecologic procedures (LUXA study)

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Laparoscopic ultrasound (LUS), performed with an endoscopic ultrasound probe, has shown potential in addressing challenges related to haptic perception and lesion detection in minimally invasive surgery. The aim of the present study was to evaluate the learning curve of gynecologic surgery fellows in achieving competency in LUS image

Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]

, 2002
Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation

Difficult Management of a Double-Lumen Endotracheal Tube and Difficult Ventilation during Robotic Thymectomy with Carbon Dioxide Insufflation

Case Reports in Surgery, 2017
Robotic surgery with carbon dioxide (CO2) insufflation to the thorax is frequently performed to gain a better operative field of view, although its intraoperative complications have not yet been discussed in detail. We treated two patients with difficult

Continuous Respiratory Oscillometry in Pediatric Laparoscopic Surgery—The COMET Study

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Laparoscopic appendectomy is the accepted surgical approach for appendicitis in centers worldwide. Laparoscopic surgery requires the creation of a pneumoperitoneum to facilitate surgical access. Laparoscopic surgery affects the respiratory mechanics of patients under general anesthesia.

Hemodynamic Effects of Prolonged Apneic Oxygenation in Laryngologic Surgery: A Randomized Controlled Pilot Trial

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Limited data exist on cardiocirculatory responses associated with extended periods of apnea during administration of high‐flow nasal oxygen for laryngologic surgery (apneic oxygenation with HFNO, AO‐HFNO). The possibility of hemodynamic compromise in the settings of acute hypercapnia, respiratory acidosis, hyperoxia, and IV ...
