Age and Regional Trends in Groin Hernia Surgery in Japan: An Analysis of Laparoscopic Repair, Outpatient Surgery, and Manual Reduction Using National Database Open Data

Annals of Gastroenterological Surgery, EarlyView.
Using National Database open data from 2014 to 2023, this nationwide study visualizes age‐, sex‐, and region‐specific trends in groin hernia surgery in Japan. Laparoscopic surgery, outpatient surgery, and manual reduction were analyzed to estimate lifetime surgical burden and patterns of emergency‐related healthcare utilization at the population level.

Impact of Distillation Column Design on Potential for the Integration of Mechanical Vapor Recompression

Chemie Ingenieur Technik, EarlyView.
Mechanical vapor recompression integration in distillation is analyzed, focusing on feed preheating and column pressure drop. Binary methanol–water and benzene–toluene separations are studied to identify optimal designs, which are further assessed in a bioethanol vacuum distillation sequence regarding energetic, ecological, and economic performance ...

Investigation of sag behaviour for aluminium conductor steel reinforced considering tensile stress distribution

Royal Society Open Science, 2021
Sag calculation plays an important role in overhead line design. Since the tensile stress of aluminium conductor steel reinforced (ACSR) is required for the sag calculation, an analysis on sag behaviour when considering the tensile stress distribution ...

A study of chevron type plate design on pressure drop and friction factor of brazed plate heat exchanger

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Brazed plate heat exchanger (BPHE) was analyzed using computational fluid dynamics (CFD) simulations by ANSYS Fluent to investigate the chevron‐patterned plates. The influence of geometric parameters, including corrugation pitch, depth, and angle was analyzed.

Thermal analysis of a commercial plate fin heat exchanger with non-uniform inlet flow conditions [PDF]

, 2016
In studies using computational fluid dynamics software, very often a uniform air stream is applied as inlet boundary condition of a heat exchanger. In actual applications, however, the inlet flow conditions are not uniform.
