Demonstration of ground‐penetrating radar as a useful tool for assessing pocket gopher burrows

Wildlife Society Bulletin, 2013
Ground‐penetrating radar (GPR) is an innovative and non‐invasive method that uses radar to penetrate the ground and develop three‐dimensional digital images of the top several meters of the earth. Ground‐penetrating radar has been used extensively in the

Clean Cut (adaptive, multimodal surgical infection prevention programme) for low‐resource settings: a prospective quality improvement study

BJS (British Journal of Surgery), EarlyView., 2020
Clean Cut is a multimodal, adaptive, checklist‐based infection prevention programme designed to improve compliance with six critical perioperative infection prevention practices. After introducing the programme at five hospitals in Ethiopia, compliance with critical infection prevention standards significantly improved and the relative risk of ...
