Author(s)
Ryo Akasaka, Eric Lemmon
A new fundamental equation of state expressed as a function of the Helmholtz energy is presented for 3,3,3-trifluoroprop-1-ene (R-1243zf). The equation is valid from the triple point temperature (122.35 K) to 430 K at pressures up to 35 MPa. The expected

Impacts of Alfalfa Nutrient Concentrate on Pellet Physical Attributes, Growth Performance, Metabolism and Nutritional Quality of Rainbow Trout, Oncorhynchus mykiss
