Randomized clinical trial of an enhanced recovery after surgery programme versus conventional care in laparoscopic Roux‐en‐Y gastric bypass surgery

BJS Open, Volume 3, Issue 3, Page 274-281, June 2019., 2019
Patients receiving enhanced recovery after surgery (ERAS) care recover faster after laparoscopic Roux‐en‐Y gastric bypass than patients receiving conventional care. Background Enhanced recovery after surgery (ERAS) programmes have led to a decreased duration of hospital stay in several surgical fields, but have not been fully tested in patients ...

Effect of Abrasive Concentration on Impact Performance of Abrasive Water Jet Crushing Concrete

Shock and Vibration, Volume 2019, Issue 1, 2019., 2019
It has been found that the impact performance of water jets can be changed by its properties, which include pressure, additive, and mode of jet. Thus, an abrasive water jet (AWJ) has been developed as a new method. However, there is little research on the effect of abrasive concentration on the impact performance of abrasive jets.

Sensitivity Studies and Parameters Identification for Noisy 3D Moving AWJM Model

International Journal of Engineering Mathematics, Volume 2016, Issue 1, 2016., 2016
This work focuses on the identification of optimal model parameters related to Abrasive Waterjet Milling (AWJM) process. The evenly movement as well as variations of the jet feed speed was taken into account and studied in terms of 3D time dependent AWJM model. This gives us the opportunity to predict the shape of the milled trench surfaces.
