My Way towards Mastery of the Russian Language and Understanding of the Russian Soul
The article was submitted on 19.01.2014.The article examines the personal comprehension and scholarly research of Russian as a foreign language. Facts of the renowned scholar’s biography are projected onto the vast field of modern Russian studies. The article studies the heuristic methods of analysis and systematization of language material connected with accentology, morphology, functional syntax, cultural linguistics, corpus linguistics, and current linguistic processes. The author describes his own scholarly pursuit and findings, including them into the context of the present, and connecting them with the issues of education, ethics, politics, culture and international contacts.В статье обсуждается проблема личностного постижения и научного исследования русского языка как иностранного. Яркие факты научной биографии известного финского ученого проецируются на обширное поле современной русистики. Обсуждаются связанные с акцентологией, морфологией, функциональным синтаксисом, лингвокультурологией, корпусной лингвистикой, активными языковыми процессами эвристические методы анализа и систематизации языкового материала. Рассуждения автора о собственных научных поисках и обретениях включены в контекст реального времени и переплетаются с проблемами образования, этики, политики, культуры и международных контактов
ALKALINE PEROXIDE BLEACHING OF HOT WATER TREATED WHEAT STRAW
The aim of this study was to evaluate the possibilities for chemical consumption reduction in P-P-Paa-P bleaching (P alkaline peroxide stage, Paa peracetic stage) of hot water treated straw and the effect of the wheat straw variability on the process. Papermaking fibre production from wheat straw using such a process could be implemented on a small scale if chemical consumption was low enough to eliminate the need for chemical recovery. The pulp properties obtained with this process are equal to or even superior to the properties of wheat straw soda pulp. The possibility of enhancing the first peroxide stage with oxygen and pressure was studied. The possibility for substitution of sodium hydroxide partially with sodium carbonate was also investigated. The objective was to achieve International Standardization Organization (ISO) brightness of 75%, with minimal sodium hydroxide consumption, whilst maintaining the pulp properties. The optimization of the peroxide bleaching is challenging if the final brightness target cannot be reduced. Results indicate that up to 25% of the sodium hydroxide could be substituted with sodium carbonate without losing brightness or affecting pulp properties. Another possibility is a mild alkali treatment between the hot water treatment and the bleaching sequence
