Abstract:
... Background: Tethered cut-to-length and cable yarding systems with tethered falling equipment are increasingly used to harvest trees from slopes exceeding 30–60% more safely and at reduced financial cost than less mechanized harvest systems. Existing studies of harvest equipment typically isolate one or two pieces of equipment in a harvest system and often occur on sites with slopes below 50% and t ...

Abstract:
... Fog harvesting has been reckoned to be one of the most facile and economical approaches to alleviating the ever-increasing global water scarcity. Janus membranes, especially metallic ones, outperform other fog collectors in terms of fog harvesting efficiencies, and they are the selection for sustainable water production as passive devices. However, there is a lack of metallic Janus membranes with ...
