A large portion of life cycle transportation impacts occur during vehicle operation, and key improvement strategies include increasing powertrain efficiency, electrification, lightweighting vehicles by reducing their mass. The potential energy benefits are large, given that 29.5 EJ was used in all modes U.S. 2016, roughly half the spent wheeled majority aircraft is to move We collect review previous work on lightweighting, identify parameters affecting environmental performance (e.g., mode,...

Long-term anticoagulation prevents recurrent thrombosis in patients with idiopathic deep venous or pulmonary embolism, but a risk of clinically important so-called major bleeding. Physician- and patient-based decisions on the optimal duration therapy are sensitive to bleeding risk. The Outpatient Bleeding Risk Index potentially provides means calculating potential using easily elicited clinical findings, but, our knowledge, authors index have provided only published validation it. We sought...

This paper highlights results from a collaborative life-cycle design project between the University of Michigan, US Environment Protection Agency and United Solar Systems Corporation. Energy analysis is critical planning tool for photovoltaic (PV) modules. A set model equations evaluating energy performance PV systems other electricity-generating are presented. The total life-cycle, encompassing material production, manufacturing assembly, use end-of-life management, was investigated. Three...

Students were free choose their topics, search for select from source materials, write up present findings in own way. The participants 11‐ 12‐year‐old pupils an open‐concept school Aberdeen, Scotland. Data took the form of fieldnotes, photocopies booklets texts, structured, unstructured, debriefing interviews, audio videotapes....

Abstract Electrification of delivery vehicles will play an important role in decarbonizing the transportation sector. As electricity‐generating technologies vary regionally and temporally, where electric are deployed when they charged determine greenhouse gas (GHG) emissions cost consequences vehicle electrification. We couple a charging model with dataset that provides hourly projections marginal electricity factors across 134 balancing areas United States. calculate over 10‐year service...

This study fills a gap in additive manufacturing life cycle assessments to improve decision-making plastic product manufacturing. assessment investigated cradle-to-gate energy consumption and greenhouse gas (GHG) emissions of multi jet fusion (MJF) three-dimensional (3D) printing technology across production quantities ranging up 100 000 parts. Results for MJF 3D site were 25% lower than the median reported value selective laser sintering. Modeled GHG part unit process increased linearly at...

Electrification of delivery fleets has emerged as an important opportunity to reduce the transportation sector's environmental impact, including reducing greenhouse gas (GHG) emissions. When, where, and how vehicles are charged, however, impact reduction potential. Not only does carbon intensity grid vary across time space, but charging decisions also influence battery degradation rates, resulting in more or less frequent replacement. Here, we propose a model that accounts for spatial...

Summary This article presents an algorithm to aid practitioners in determining the most appropriate method estimate carbon dioxide emissions from electricity load. Applications include sustainability assessments of products, processes, energy efficiency improvements, changes generation infrastructure, and demand. Currently, there is no consensus on methods for calculating greenhouse gas resulting specific loads. Previous research revealed significant differences when different were used, a...
