Improving the rotary kiln-electric furnace process for ferronickel production: Data analytics-based assessment of dust insufflation into the rotary kiln flame

Alexandria Engineering Journal, 2022
Ferronickel contains 60–80 wt% Fe and 40–20 wt% Ni and is a feedstock for manufacturing stainless steel and other ferrous alloys. The primary pyrometallurgical route to produce ferronickel from laterite nickel ores is the Rotary Kiln-Electric Furnace ...

Chinese Guidelines for the Diagnosis and Surgical Treatment of Adult Obstructive Sleep Apnea (2024)

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Obstructive sleep apnea (OSA) is a common chronic disorder characterized by abnormal breathing during sleeping. OSA can damage various organs throughout the body and is burdensome, both socially and economically. Moreover, as OSA has been increasingly studied in recent years, new evidence‐based guidelines for its diagnosis and surgical ...

Endoscope‐Assisted Nipple‐Sparing Mastectomy With Immediate Implant Reconstruction: A Retrospective Study

World Journal of Surgery, EarlyView.
Breast cancer surgery increasingly favors nipple‐sparing and endoscopic techniques to optimize oncological safety, cosmetic outcomes, and patient satisfaction. We aimed to evaluate and compare the clinical efficacy and postoperative safety profiles of endoscope‐assisted and conventional open approaches for nipple‐sparing mastectomy with immediate ...

Carbon dioxide insufflation during withdrawal of the colonoscope improved postprocedure discomfort: A prospective, randomized, controlled trial

Kaohsiung Journal of Medical Sciences, 2012
In colonoscopy, the question of when and how to use carbon dioxide (CO2) insufflation remains uncertain. Inspection for the pathological changes during colonoscopy takes place during the withdrawal of the scope.

Automated control for investigation of the insufflation-ventilation interaction in experimental laparoscopy.

PLoS ONE, 2023
In laparoscopic surgery the abdominal cavity is insufflated with pressurized carbon dioxide gas to create workspace. This pressure is exerted through the diaphragm onto the lungs, competing with ventilation and hampering it.

Exploratory Laparotomy After Routine Cardiac Surgery: Results From 17,000 Patients

World Journal of Surgery, EarlyView.
Exploratory laparotomy is rare after open‐heart surgery, and it was performed for gastrointestinal complications that occurred in the context of other severe postoperative complications. Several factors were associated with the need for exlap, including increasing age, pre‐existing renal and vascular disease, and pre‐ and post‐operative shock. ABSTRACT

Measuring organ shift and deformation for port placement in robot-assisted minimally invasive surgery

Laparoscopic, Endoscopic and Robotic Surgery, 2020
Objective: Port placement is a crucial pre-operative task in robot-assisted minimally invasive surgery. Due to the insufflation process, the abdominal shape is deformed while the internal organs are shifted in position.
