Для выявления технологических особенностей Жалованной грамоты Петра I были проведены оптико-физические (ИК-рефлектография, микроскопическое исследование с последующей фотофиксацией), а также комплексные физико-химические исследования проб основы, красочных слоев, связующих. Использованы методы микроскопии в отраженном свете, микрохимии, ретгенофлюоресцентного анализа, ИК Фурье спектроскопии, морфологического анализа для определения материалов по волокну. На основании полученных данных была разработана реставрационная программа. На первом этапе выполнен демонтаж грамоты, включающий отделение тканевой обложки со шнурами и печатью от пергаментных листов с текстом. In order to identify the technological features of the Letters patent by Peter I, optical-physical (IR reflectography, microscopic examination and subsequent photo-recording), as well as complex physical and chemical studies of samples of the base, colorful layers, binders were carried out. The methods included microscopy in reflected light, microchemistry, x-ray fluorescence analysis, IR-Fourier spectroscopy, morphological determination of the materials of the certificate and the cover of the fiber. Based on the data obtained, a restoration program was developed. At the first stage of the conservation, the dismantling of the certificate was carried out, including the separation of the fabric cover with cords from parchment sheets with text.

Rostov Region belongs to the highly protected natural territories characterized by the continuous plowing. There territories are the only reserves with the soils preserved in their natural state. However, these areas often lack detailed information about the soils quality and composition. Surveying soils on these territories is crucial for determination of their basic physical and chemical properties. The resulted compilation of soil maps could lay a foundation for creating the Red Book of Soils and the formation of a section in the soil-geographical database of the Russian Federation. Subsequently, such information can be used as a background data for the main types of soils in the region. It will be also valuable during monitoring and justification of conservation measures.
