This paper explains design decisions forming a foundation of WordBricks — an intelligent computer-assisted language learning environment, recently initiated at our institution. WordBricks is intended to serve as a “virtual language lab” that supports open experiments with natural language constructions. Being based on dependency grammars, this instrument(More)
The nucleotide sequences of nuclear gene EF-1α were determined for 49 species of Lasiocampidae from Eurasia and Africa. Based on these data, the phylogeny of the family was reconstructed using the minimum evolution, maximum parsimony, maximum likelihood, and Bayesian inference methods. The molecular genetic research confirms the monophyly of Malacosominae(More)
In this paper, we briefly describe the limitations of present CALL systems, caused both by technological factors and by the limited agenda of CALL developers, whose design goals tend not to result in software tools for practical everyday language learning activities. We also note the lack of creative new ways of using computers in language education and a(More)
Tryptophan hydroxylase is one of the key enzymes involved in serotonergic metabolism. In many studies, an association between the TpH gene and human mentality, as well as mental disorders was demonstrated. This study was designed to analyze the association between three TpH gene polymorphisms (A218C, T3792A, and (CT) n (CA) n (CT) n ) and endogenous(More)
The nucleotide sequences of mitochondrial genome fragments containing the genes coding for cytochrome oxidase subunit III (COIII) and 12S ribosomal RNA of common European viper and Nikolsky’s viper from various habitats (Saratov, Samara, and Penza oblasts; Chuvash Republic; and the Republic of Mordovia) were determined. According to the sequencing data, all(More)
