Perspectives on Climate Change in Education for Sustainability: Linking Concepts and Skills for a Practical Ecological Transition

open access: yesSustainable Development, EarlyView.
ABSTRACT ‘Hard’ natural sciences have extensively been used to provide evidence that climate change is happening and climate action is needed. If the contribution of our economic activities to disturbing our climate systems is now largely accepted, the way in which we design and operationalise ‘climate action’—how we transition to more sustainable ...

Dynamically distributed district heating for an existing system [PDF]

open access: yes
The study in hand introduces the concept of dynamically distributed district heating. The concept addresses the challenges related to transforming an existing 3rd generation district heating system into a 4th generation system, one area at a time.

Effect of Metal–Metal Distance on the Performance of Dual‐Atom Catalysts for the Oxygen Reduction Reaction: A Density Functional Theory and Micro‐kinetics Study

open access: yesSmall, EarlyView.
Density functional theory calculations and microkinetic modeling were carried out on 108 dual‐atom catalysts with varied metalmetal distances ranging from 2.2 to 3.5 Å. The results reveal that moderate spacing of around 3.0 Å promotes bridging oxygen adsorption and dissociative reduction pathways, weakens the hydroxylhydroperoxyl scaling relationship ...

Towards 4th generation district heating: Prediction of building thermal load for optimal management

open access: yesEnergy, 2019
Abstract One of the requirements for the transition from conventional district heating (DH) systems to 4th generation DH (4GDH) systems is the knowledge of system dynamics. Forecast of thermal request profiles of buildings is crucial to optimize the operating conditions. In fact, when this is available, the thermal load evolution at the plants can be

Influence of Hydrogen Fuel Mixtures on the Oxide Scale Formation of Low‐Carbon Steels in Reheating Furnace Conditions

open access: yessteel research international, EarlyView.
This work illustrates how substituting natural gas with hydrogen as fuel in the reheating furnace will influence the oxide scale formation on the steel surface. Thermogravimetric analysis and characterization techniques are used to investigate oxidation behavior and the formation of oxide phases.

Integration of Flow Temperatures in Unit Commitment Models of Future District Heating Systems

open access: yesEnergies, 2019
The transformation of heat supply structures towards 4th generation district heating (4GDH) involves lower supply temperatures and a shift in technology. In order to assess the economic viability of the respective systems, adequate unit commitment models

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,
