This paper studies the influence of ammonia gas on wood color changes in response to an increasing demand for dark colored wood specimens.The darker wood color in ammonia fuming is accomplished through chemical reactions between ammonia gas and wood compounds.We exposed oak, maple, spruce, and larch wood samples to ammonia gas for 16 days.During fu
We present a small-scale pneumo-hydraulic energy storage system (ss-CAES) which can provide frequency support to a power grid, as fast instantaneous reserve.This system is designed to be maintained at rest until called, thus avoiding idling costs.It utilizes a hydraulic drive train which transmits very high Tracking Devices torque directly to the s
Abstract Background Integration and analysis of phenotype data from humans and model organisms is a key challenge in building our understanding of normal biology and pathophysiology.However, the range of phenotypes and anatomical details being captured in clinical and model organism databases presents complex problems when attempting to match Horn
