The JKR formalism in applications to problems of adhesive contact
No full textThe JKR (Johnson-Kendall-Roberts) problem of adhesive contact between elastic spheres is an example of a mathematically beautiful theory that has many practical applications. However, it would be erroneous to reduce the JKR theory to just the problem of adhesive contact between spheres. Indeed, simultaneously with the presentation of the JKR theory, Kendall (J Phys D Appl Phys 4:1186–1195, 1971) applied the equilibrium theory of adhesion to bodies of other geometries and coatings. It gives a review of applications of the JKR formalism to axisymmetric indenters of various shapes, various elastic materials, different conditions of contact, and elastic structures. These structures include thin and thick elastic layers and atomically thin stretched membranes. The JKR formalism means that an adhesive contact problem may be solved by combining two ideas: (1) the Derjaguin balance energy approach (Derjaguin, Kolloid Z 69:155–164, 1934) and (2) superposition of solutions to two non-adhesive contact problems (the Hertz-type and the Boussinesq-type problems). The JKR formalism may be used if the distance between the free surface of the material and the indenter surface increases rapidly at the periphery of the contact region and the solutions of two contact problems having the same contact area may be superimposed on each other. It is shown that the JKR formalism may be reinforced if one employs the properties of slopes of the force-displacement diagrams of non-adhesive indentation. For the first time, such reinforcements were demonstrated explicitly by the author (Borodich, Adv Appl Mech 47:225–366, 2014). It is argued that the JKR formalism may be applied to an enormous number of adhesive contact problems for various elastic structures

South Ural State University, Chelyabinck, Russian FederationСтатья посвящена искусству исполнения буквиц в старопечатном стиле в рукописных книгах выдающимся книгописцем и художником-знаменщиком Федором Басовым в конце XVI — начале XVII вв. Используя метод элементно-структурного анализа, автор исследует композиционные решения и элементы, выявляя на основе этого заимствованные и авторские принципы Федора в работе над созданием инициалов. Проводится сравнение буквиц, исполненных Федором Басовым, с орнаментикой, выполненной в печатных московских изданиях и рукописных книгах, оформленных братьями художника-знаменщика — Стефаном и Гаврилой
(по прозвищу Иван) Басовыми. Автор устанавливает способы орнаментации украшений и особенности творческого почерка мастера в хронологическом порядке. The article is devoted to the ornamental art of an Early Printed style in Old Russian manuscripts at the last quarter of the 16th — the first third of the 17th centuries case study of the initial letters by Feodor Basov. The author examines the methods of ornamentation and the features of the master’s creation in the chronological order. The authors compare the ornamental initial letters by Feodor Basov, the ornamental initial letters by his brothers Stefan and Gavrila (nicknamed Ivan) Basovs and the ornamental initial letters of the Moscow printed books. The author analyzes compositional
solutions and elements and, on the basis of this, identifies borrowed and author’s principles by Feodor at the creation of initials
The sources of Reforms of Peter I in reforms of the state administration in the government of Feodor III and in the government of regent Sofia
No full textThe article is devoted to an examination of a question of the reform of the state administration in the government of Feodor III and in the government of regent Sofia in the last quarter of XVII century. The author tries to find the parallels between the reforms of the state administration of Peter I and the reforms of the state administration of Feodor III and I and regent Sofia. The author tries to find, what were the reasons of the reforms and the results and significance of this phenomenon

No full textThe draining-drainage systems carried out for eliminating the excessive humidity on agricultural lands were designed
with respect to the exploitation of surfaces on the draining sectors. Since upon the construction and reconstruction of
property rights the orientation of the absorbent drainage lines and drying network was not considered, the plots of land
are either perpendicular on, or parallel to, or even form an acute angle with these absorbent drains and/or drying canals.
The different soil works performed on each individual plot has led, in time, to the formation of ridged strips of variable
widths, level differences and transverse slopes, depending on the width of the plots, on the manner in which they are
used and on the machinery employed for the agricultural works conducted. The land shaping in ridge straps and their
different orientation of to the drain lines and the channel network leads to a non uniform elimination of the water excess
on the drained land. On the arable drained land surfaces with individual parcels orientated along the level curves, the
land shaping in ridge straps produced water stagnation on drains and the accentuation of excessive humidity especially
in spring and raining seasons which lead to the gradual passing of the parcel to a lower category of use, that is
grasslands. Non-ridged plots enjoy better excessive water removal, which enables farmers to perform adequate and
timely spring works and thus have better agricultural productions. The draining-drainage systems carried out for
eliminating the excessive humidity on agricultural lands were designed with respect to the exploitation of surfaces on
