The course of thermal behavior of a fresh bituminous high-volatile coal during carbonization and pyrolysis was compared to that of this coal thawed after storage.The research was carried out using the following techniques: X-raying, thermogravimetry/Fourier transform-infrared spectroscopy (TG/FT-IR), extraction, Diffuse Reflectance Infrared Fourier
Polymer networks based on cyclodextrin and polyethylene glycol were prepared through polyaddition crosslinking using isophorone diisocyanate.The envisaged material properties are the hydrophilic character, specific to PEG and cyclodextrins, and the capacity to encapsulate guest molecules in the cyclodextrin T Disc cavity through physical interactio
Bump-type foil bearings have demonstrated excellent performance in service experiences in recent 30 years.Due to their special structures, the performance prediction models must couple the air pressure with the elastic deflection of the compliant foil structure.The solution of air pressure has been well settled in the hydrodynamic lubrication theor
Durags For modeling the interpretation process of NL sentences we use the mechanisms implying semantic networks that assure syntactic - semantic text interpretation (SSI), including an understanding axiomatic model, interpretation model and denotation model to represent the result of SSI.These models estimate the correctness and the consistency of
The censorship process during the New Economic Crewneck Policy Period was rather unbalanced due to the human factor.Up until 1928, certain stages of censoring the manuscript that started with initial reading and resulted in the approving mark on the typographical card, could be omitted, as the case of Saratov author L.A.Slovokhotov illustrates.The
