Thermogravimetric Studies on Condensed Wood Residues in Polyhydric Alcohols Liquefaction
To further clarify reasons for formation of condensed residues during the last stage of wood liquefaction in the medium of polyhydric alcohols and sulfuric acid catalyst, the weight loss behaviors and thermal reaction kinetics of condensed residues were studied by thermogravimetric analysis (TGA). Simultaneously, chemical methods were used to analyze the contents of lignin, cellulose, and holoc...
متن کاملWine secondary aroma: understanding yeast production of higher alcohols
Contribution of yeasts to the sensory attributes of fermented foods and beverages goes far beyond sugar consumption and ethanol and carbon dioxide production. It includes some major by-products of fermentation, like glycerol or acetic acid, and hundreds of aroma-active compounds, including higher alcohols, esters, aldehydes, organic acids, volatile fatty acids or carbonyl compounds, as main con...
متن کاملMetabolic Engineering of Microorganisms for the Production of Higher Alcohols
Due to the increasing concerns about limited fossil resources and environmental problems, there has been much interest in developing biofuels from renewable biomass. Ethanol is currently used as a major biofuel, as it can be easily produced by existing fermentation technology, but it is not the best biofuel due to its low energy density, high vapor pressure, hygroscopy, and incompatibility with...
متن کاملHigher representations on the lattice: perturbative studies
We present analytical results to guide numerical simulations with Wilson fermions in higher representations of the colour group. The ratio of Λ parameters, the additive renormalization of the fermion mass, and the renormalization of fermion bilinears are computed in perturbation theory, including cactus resummation. We recall the chiral Lagrangian for the different patterns of symmetry breaking...
متن کاملPharmacological studies on fatigue. I.
Considerable investigation has been done as to whether or not a particular drug is effective for recovery of an animal after it has become exhausted. Experiments have included screening antifatigue effect on animals, but applications have not been generally established. Effects of drugs on psychological fatigue as seen in man can hardly be inferred from tests on animals. Even physiological effe...
