In this study, we elucidate the reaction kinetics for simultaneous hydrodeoxygenation of xylitol to 1,2-dideoxypentitol and 1,2,5-pentanetriol over a ReOx-Pd/CeO2 (2.0 weight% Re, 0.30 Pd) catalyst. The was determined be zero-order with respect xylitol. activation energy elucidated through an Arrhenius relationship as well non-Arrhenius kinetics. investigated at 150–170 °C constant H2 pressure ...
abstract translation has become a cultural act which plays a significant role in human life. with the emergence of functional translation theories, and skopos theory in particular, translation has been considered as a purposeful, interpersonal and intercultural activity which is produced for particular recipients and directed by a specific purpose. this purpose determines the translatio...
Color is an important qualitative factor in tomato products such as tomato paste which is affected by heat processing. The main goal of this study was to evaluate the degradation kinetics of tomato paste color during heat processing by Arrhenius equation and modeling of these changes by response surface methodology (RSM). Considering this purpose, tomato paste was processed at three temperature...
ABSTRACT This paper examines the astronomical theory of ice ages James Croll (1821–1890), its influence on contemporaries John Tyndall, Charles Lyell, and Darwin, subsequent development climate change science, giving special attention to work Svante Arrhenius, Nils Ekholm, G. S. Callendar (for carbon dioxide theory), Milutin Milanković theory). Croll's insight that orbital elements triggered fe...
