How Uncertain is the Emergence of Knowledge Related to the United Nations Sustainable Development Goals? An Analysis of Scientific Knowledge Diversification at Utrecht University

open access: yesSustainable Development, EarlyView.
ABSTRACT The study of synergies and trade‐offs among the Sustainable Development Goals (SDGs) has captured growing scientific interest. However, how scientific knowledge addressing multiple SDGs emerges and contributes to improving synergies and addressing trade‐offs remains unclear.

Analysis of Stirling engine’s performance in recovering waste heat from wood pellet, coconut husk and bagasse

open access: yesJournal of Thermal Science and Technology
In recent years, industrial boilers that generate power from biomass have drawn a lot of attention. Nevertheless, a sizable portion of thermal energy is frequently lost to the environment as flue gas throughout the process.

Design analysis methods for Stirling engines [PDF]

open access: yesJournal of Energy in Southern Africa, 2008
Worldwide attempts are being made to increase the use of our renewable energy sources as well as to use our current fossil fuel energy sources more effi-ciently. Waste heat recovery forms a substantial part of the latter and is the focus of this project.

Labour's Commitment to 1.5 Million New Homes: Housing Delivery as an Orchestrator‐Intermediary Challenge

open access: yesThe Political Quarterly, EarlyView.
Abstract In the UK, the new Labour government has linked the intention to deliver more homes to reform of the planning system, which is seen as a key barrier. Two assumptions inform this reform. First, the system is sound, but there are problems with its administration.
