Adiabatic electron affinities, optimized molecular geometries, and IR-active vibrational frequencies have been predicted for small cyclic hydrocarbon radicals C(n)H(2)(n)(-)(1) (n = 3-6) and their perfluoro counterparts C(n)F(2)(n)(-)(1) (n = 3-6). Total energies and optimized geometries of the radicals and corresponding anions have been obtained using

The aims of this study were to determine energy requirement and global warming potential (GWP) in low and high input wheat production systems in western of Iran. For this purpose, data were collected from 120 wheat farms applying questionnaires via face-to-face interviews. Results showed that total energy input and output were 60,000 and 180,000 MJ ha(-

In this study, the energy and exergy performance of secondary loop systems (2LPs) using HFC-152a and HC-290 was investigated. These 2LPs were compared with a HFC-134a direct expansion system as a baseline system. As compared with the baseline, tested refrigerant charge amount was reduced by 28% for the HFC-152a 2LP and 60% for the HC-290 2LP.
