Different refrigerants on high and low
WebIn this paper, the results of heat capacity measurements performed on the polycrystalline Tb1-xErxNi2 intermetallic compounds with x = 0.25, 0.5 and 0.75 are presented. The Debye temperatures and lattice contributions as well as the magnetic part of the heat capacity were determined and analyzed. The heat capacity measurements reveal that the substitution … WebAn important issue that has received little attention to date is how different types of work activities may interplay to influence workday energy, a critical resource for individuals’ performance at work. Integrating the notion of workday design with event system theory, we examine two prominent types of work activities for knowledge workers—meetings and …
