From Angiosomal to Bi‐Angiosomal and Extra‐Angiosomal Pedicled Perforator Flaps: Optimizing the Use of Local Tissues in Abdominal Wall Reconstruction

Microsurgery, Volume 44, Issue 6, September 2024.
ABSTRACT Introduction The use of free‐style and propeller perforator‐based flaps has been popularized for the reconstruction of moderate size defects in the trunk and extremities, while their application in the field of abdominal reconstruction is seldom reported. The purpose of this report is to describe the authors experience with the use of pedicled

Fail to plan, plan to fail. Are education policies in England helping teachers to deliver on the promise of democracy?

British Educational Research Journal, Volume 50, Issue 4, Page 1831-1856, August 2024.
Abstract This paper examines three questions: (1) (How) Is democracy promoted in secondary schools in England? (2) How is the promotion of democracy understood in education and teacher education policy? and (3) To what extent does existing education policy benefit the promotion of democracy in schools in England?

Effect of an Exhaust Heat Exchanger with Inserts on the Performance of Thermoelectric Generators

Journal of Engineering, Volume 2024, Issue 1, 2024.
A thermoelectric generator is used as a waste heat recovery system for generating electric power. The thermoelectric generator system consists of an exhaust heat exchanger, a thermoelectric module, and a water heat exchanger. The aim of the current work is to explore different types of inserts used in the test section of the exhaust heat exchanger and ...

Review of Some Methods for Improving Transient Response in Automotive Diesel Engines through Various Turbocharging Configurations

Frontiers in Mechanical Engineering, 2016
Turbocharged diesel engines suffer from poor drivability, mostly at low loads and speeds, leading also to overshoot in exhaust emissions (primarily PM/soot and NOx) during the transient operation after a speed or load increase.
