The paper specifies associative text fields, which have been identified as a result of a “nonlinear reading” process of the Tatiana Tolstaya’s narration, which is called “Krug” (“Круг”). Likewise, a quite close bond between associative field ЖИЗНЬ and associative fields: КРУГ, ПУТЬ, is being established. A semantic gestalt of a presented field is being emerged by the process of analyzing associates, which are referring to an associative field ЖИЗНЬ. According to the author’s opinion, the semantic gestalt might be considered as an explication of a specific concept ЖИЗНЬ features. Thus, author makes a conclusion, that a semantic gestalt of an associative text field might have cognitive interpretation.

A study of hydrogen reduction of metallic manganese from iron-manganese ores of colloidal origin has been carried out. The structure of oxides and hydroxides of iron and manganese are typical structures of crystallized dispersed systems with a solid dispersed medium – colloids. The optimal temperature and gas supply rate have been experimentally selected to facilitate the course of an intensive reduction reaction. The reduction of manganese occurs sequentially from higher oxides to S.G.lower ones to pure manganese. Preliminary mechanical activation of the ore on the vibrator contributed to the complete course of the manganese reduction reaction.
