Development of granular-medium-based energy management system for automotive bumper applications
Automotive bumpers are installed primarily to minimize damage and harm to both the automobile and passengers during minor and low speed collisions. The efficacy of the current bumper systems lies in absorbing the impact ...
Markers of hydration status in a 3-day trail running event
(Lippincott, Williams & Wilkins, 2013)
Objective: To examine the relationships between changes in static prestage and poststage measures of commonly used hematological and urinary markers of hydration status and body mass (BM) in participants in a 3-day trail ...
Reuse of cured epoxy as a reinforcement in an epoxy composite
This article discusses the reuse of a thermoset-based epoxy polymer. In this method, cured epoxy polymer is ground to powder of particle size ranging from 1 to 30 μm. The ground epoxy is then filled in an epoxy polymer to ...
