Abstract. In the present work, the procedure of the estimation of the thermal activation parameters from the data of dilatometric measurements and the results of its application to the Zr-Cu-Nb amorphous alloy discussed. The determination of the thermal activation parameters of the processes occurring in materials under known temperature-force conditions can be useful for the identification of the structural mechanisms of phase transformations and the evolution of defect structure. We used the data of dilatometric measurements for evaluating the effective activation energy. This method exhibits some advantages over the conventional one due to the design features of dilatometers. First, it ensures the precise measurement of strains; second, the assigned temperature regime is very precisely maintained both at the stage of heating and upon isothermal holding; third, it ensures a high-speed continuous record of the experimental data. The developed method of evaluating the effective activation energy from the results of dilatometric experiments provides statistically reliable results. The data of the photometric analysis of structure images are in accordance with the results of dilatometric experiments.

Abstract. Amorphous materials give the possibility to observe the phase and structural transformations in sufficiently narrow temperature intervals with the retention of their unchanged chemical composition. The present report is concerned with the results of the study of structure evolution and its dependence on magnetic field upon heating in the Fe-Zr-B amorphous alloy by the method of the photometric analysis of structural images (PHASI). The PHASI method makes it possible to establish the effect of external temperature and magnetic fields on the brightness spectra of the reflection from the surface of the object under study and the distribution of the zones, in which these changes are localized. The established temperature dependence of the energy characteristics of the reflection brightness spectrum in arbitrary units indicates the complex structural transformations caused by heating of the alloy under study. Also it is shown that the magnetic field produces residual structural changes in the alloy in comparison with its initial state.

This article aims to explain why the dialectal identification of the Selkup texts compiled by Nikolaj Grigorovskij in the 19th century is still open. It also provides preliminary results on the isoglosses within the Southern dialectal group and strategies on how to address this problem. In order to advance the research, the first Selkup books of the 19th century (1879) have been converted into a digital annotated corpus of texts. Their analysis has revealed language features which, on the one hand, are accurately verified by Selkup material of the 20th century (on the example of the verb conjugation and the noun declension paradigms and the main Selkup isoglosses identified by Helimski. On the other hand, it has shown that the dialectal phenomena are insufficiently described. The article also gives the combined variant of Grigorovskij’s biography existing as fragments in different sources. Kokkuvõte. Nadežda Fedotova: Esimeste N. P. Grigorovski sölkupi raamatute taust ja teaduslik potentsiaal. Siinse artikli eesmärk on välja selgitada, miks on siiani lahtine 19. sajandil Nikolaj Grigorovski poolt kogutud sölkupi tekstide murdeline määratlus. Ka annab artikkel esmased tulemused isoglosside piiride kohta lõuna-sölkupi murdegrupis ja pakub strateegiaid sellele probleemile lähenemiseks. Uurimisteema arendamiseks on esmalt esimesed 19. sajandi sölkupi raamatud (1879) viidud digitaalse tekstikorpuse kujule. Tekstianalüüs on välja toonud keelelised tunnused, mida ühest küljest kinnitavad ka 20. sajandi sölkupi materjalid (seda verbi pöördeliste ja noomenite käändeliste paradigmade põhjal ning põhiliste sölkupi isoglosside põhjal, mille on välja toonud Helimski 2004). Teisalt aga näitab analüüs, et murdelised nähtused on ebapiisavalt kirjeldatud. Artikkel sisaldab ka erinevates allikates esinevatest fragmentidest kokku kombineeritud varianti Grigorovski bibliograafiast. Аннотация. Надежда Федотова: История и перспектива исследования первых книг на селькупском языке Н. П. Григоровского. Целью статьи является выявление причин, в связи с которыми проблема определения диалектной принадлежности первых селькупских текстов, собранных в XIX веке Николаем Григоровским, остается открытой. В статье даны предварительные варианты изоглосс, позволяющие отличить южную диалектную группу селькупского языка от других диалектных групп. С тем чтобы углубить исследование, первые селькупские книги XIX века (1879) были оцифрованы и преобразованы в аннотированный корпус текстов. Анализ на основе данного корпуса позволил обнаружить языковые явления, которые, с одной стороны, точно совпадают с селькупскими материалами, зафиксированными в XX веке (на примере парадигм спряжения селькупских глаголов и склонения существительных, а также с основными изоглоссами, предложенными Хелимским [Xelimskij 2004]). С другой стороны, они демонстрируют диалектные явления, которые недостаточно подробно описаны в литературе. В статье также предложена наиболее полная версия биографии Григоровского как компиляция из различных источников.
