The paper reports on the recent forum RU-EVAL ‒ a new initiative for evaluation of Russian NLP resources, methods and toolkits. It started in 2010 with evaluation of morphological parsers, and the second event RU-EVAL 2012 (2011-2012) focused on syntactic parsing. Eight participating IT companies and academic institutions submitted their results for corpus parsing. We discuss the results of thi...

the paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. this experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. th...

Trivalent and hexavalent chromium continuous biosorption was studied using residual brewer Saccharomyces cerevisiae immobilized in volcanic rock. The columns used in the process had a diameter of 4.5 cm and a length of 140 cm, working at an inlet flow rate of 15 mL/min. Breakthrough curves were used to study the yeast biosorption behavior in the process. The saturation time (ts) was 21 and 45 h...

Nine samples collected from the Upper Cretaceous Second White Speckled Shale Formation at Highwood River outcrop in southern Alberta were geochemically characterized for their oil contents, physical states, and chemical compositions. Cold extraction was performed on 8–10 mm 2–5 chips sequentially to obtain first second extractable organic matter (EOM-1 EOM-2), while Soxhlet powder previously ex...

Marine organic-rich shale is widely distributed in the Upper Ordovician Wufeng Formation (WF-F) and Silurian Longmaxi (LMX-F), making it an important target for gas exploration development. In order to clarify paleoenvironment evolution characteristics effect of depositional environment on organic matter (OM) accumulation marine Formations, a series geochemical petrological experiments were car...

Late Carboniferous to early Permian organic-rich sedimentary successions of late-orogenic continental basins from the northeastern Massif Central (France) coincide with both Variscan mountain dismantling and acme long-lasting Paleozoic Ice Age. Here, we investigate carbon nitrogen cycles in newly dated Decize–La Machine Autun during these geodynamic climate upheavals. The organic matter has bee...
