in this paper, absorption spectra of both solution and films of cyano azobenzene polymer are investigated. the analysis of overlapped absorption spectra of polymer, related to trans and cis isomers, shows that the population of cis isomers is higher than trans isomers. it means that, cyano azobenzene molecules have a folded structure in polymer, in thermal equilibrium. presence of cyano molecul...

this experiment was conducted to evaluate the effects of caffeine and trans-cinnamaldehyde (tc) on growth performance, hematological parameters, stress hormones, immune response, and some blood parameters of broiler chickens. three hundred fifty 1-d-old broiler chicks were randomly assigned to 7 dietary treatments (five pens/ treatment of 10 male broilers each) in a completely randomized design...

trans-fatty acids (tfa) are known as a risk factor for coronary artery diseases. trans-11 vaccenic acid [va; 18:1(n-9)], known as the major trans fatty acid in milk fat, is a positional and geometric isomer of oleic acid and a precursor of conjugated linoleic acid (cla) in human . this study was carried out in order to investigate the effect of cis and trans vaccenic acids on expression of intr...
