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

open access: yesBritish 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?

Increasing exhaust temperature to enable after-treatment operation on a two-stage turbo-charged medium speed marine diesel engine [PDF]

open access: yes, 2018
Nitrogen-oxides (NOx) are becoming more and more regulated. In heavy duty, medium speed engines these emission limits are also being reduced steadily: Selective catalytic reduction is a proven technology which allows to reduce NOx emission with very high

Global Reparations within Capitalism: Aspirations and Tensions in Contemporary Movements for Reparatory Justice

open access: yesDevelopment and Change, Volume 55, Issue 4, Page 560-600, July 2024.
ABSTRACT The idea of global reparations has received increasing attention in recent years, not only with respect to legacies of slavery and colonialism, but also to interrelated issues such as climate change, debt crisis, or ongoing financial transfers from the Global South to the Global North. This article, which introduces and sets the Debate for the

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

open access: yesJournal 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

open access: yesFrontiers 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.
