The calculation of dynamic ecological footprint on the basis of the dynamic input-output model [PDF]

open access: yes, 2010
The Leontief input-output model is widely used to determine the ecological footprint of consumption in a region or a country. It is able to capture spillover environmental effects along the supply change, thus its popularity is increasing in ecology ...

Compact and Broadband Edge Coupler Based on Multi-Stage Silicon Nitride Tapers

open access: yesIEEE Photonics Journal, 2020
We have proposed and experimentally realized an ultra-compact and broadband silicon nitride edge-coupler that enables high coupling efficiency. The proposed coupler was realized by concatenating short tapers in four stages, whose angles were designed to ...

Outside-In Anterior Cruciate Ligament Revision With Lateral Tenodesis and High-Strength Suture Augmentation Is Easy to Perform With the Iliotibial Band

open access: yesArthroscopy Techniques, 2021
We describe a technique for revision anterior cruciate ligament (ACL) surgery using a 15-cm strip of the iliotibial band as a graft and the gracilis tendon if available. An internal brace is added to augment the graft.

Use of inadequate data and methodological errors lead to a dramatic overestimation of the water footprint of Jatropha curcas [PDF]

open access: yes, 2009
In their recent article, Gerbens-Leenes et al. (1) calculated the water footprint (WF, the amount of water required to produce 1 GJ of energy) of several bioenergy crops. One of the most remarkable findings of this study was the very high water footprint

Spudcan Reinstallation Close to Natural Footprints Considering Strength Reduction: Insights from Single-Factor and Orthogonal Experiments

open access: yesApplied Sciences
In offshore jack-up operations, it is common to reinstall spudcans close to existing footprints, which could result in asymmetric soil distribution and potential instability risks. This study investigates the mechanical behavior and stability of spudcans
