Carbon Footprint: A Catalyst for Life Cycle Assessment?
Journal ArticleDOI
LCA of soybean meal
Randi Dalgaard,Randi Dalgaard,Jannick Højrup Schmidt,Niels Halberg,Per Christensen,Mikkel Thrane,Walter A. Pengue +6 more
TL;DR: The study clearly shows that consequential LCAs are quite easy to handle, even though it has been necessary to include production of palm oil, rapeseed and spring barley, as these production systems are affected by the soybean oil co-product.
Journal ArticleDOI
Problem-Oriented and Project-Based Learning (POPBL) as an Innovative Learning Strategy for Sustainable Development in Engineering Education.
TL;DR: In order for engineers to be able to handle sustainability-related problems, their education needs to allow for interplay, mix and diversity; aspects that a problem-oriented and project-based learning approach will involve.
Journal ArticleDOI
A comparison of single-lead atrial pacing with dual-chamber pacing in sick sinus syndrome
Jens Cosedis Nielsen,Poul Erik Bloch Thomsen,Søren Højberg,Mogens Møller,Thomas Vesterlund,Dorthe Dalsgaard,Leif Spange Mortensen,Tonny Nielsen,Mogens Asklund,Elsebeth V. Friis,Per Christensen,Erik H. Simonsen,Ulrik H. Eriksen,Jensen G,Jesper Hastrup Svendsen,William D. Toff,Jeff S. Healey,Henning Rud Andersen +17 more
TL;DR: In patients with sick sinus syndrome, there is no statistically significant difference in death from any cause between AAIR pacing andDDDR pacing, and these findings support the routine use of DDDR pacing in these patients.
Journal ArticleDOI
Energy system analysis of marginal electricity supply in consequential LCA
TL;DR: In this article, the authors discussed the environmental consequences of marginal electricity supplies in consequential life cycle assessments (LCA) and examined environmental characteristics by identifying affected activities, i.e. often the marginal technology.
