‘The Reconstruction of the Past is the Task of Historians and not Agents’

State security archives in Eastern Europe are shedding new light on the operative practices of the secret services and their interaction with performance art. Surveillance, tracking, undermining, disruption, writing of reports, and measure plans were different operative methods to be carried out in continuous repetitive processes. This paper argues that, through these repetitive working processes, state security agencies were permanently engaged in different forms of reenactments: of orders, legends, report writing, and inventing measure plans. With this operative reenactment, state security agencies not only tried to track down facts but also created ‘fake facts’ serving their agenda. These `fake-facts` were then again repeated and reenacted by informants endlessly to be `effective` in the surveillance and elimination of performance art.

Operative methods of fixation of the spine. Shamov (Nov. Chir. Archives, 1922)

Currently, surgical methods of spinal fixation in tuberculous spondylitis are quite numerous. Based on a review of the literature and 50 own clinical cases, the author considers the following to be the most appropriate among them.

CONFIDERATION OF NAVIGATION DANGER AT THE CHOICE OF MANOEUVRE OF DIVERGENCE OF SHIP WITH TWO TARGETS

It registers in the publication, that one of major is the problem of providing of safety of navigation, the successful decision of which conduces to the decline of harm of human life and environment. Paid attention, that sailing of maritime vessels in the straitened districts is considerably complicated by the navigation obstacles and intensive navigation, which create pre-conditions for the origin of emergency situations, thus sailing in the straitened districts is characterized by the fleeting change of navigation situation, that requires development of operative methods of estimation of danger of rapprochement and choice of safe maneuver of divergence. The high level of the use on the ship of information technologies determines expedience of computer realization of the developed methods of prevention of collision of vessels. It is specified, that in the conditions of intensive navigation there are the situations of dangerous rapprochement of ship with two targets at presence of navigation danger in the district of maneuvering. The analysis of the last achievements and publications is resulted on the theme of prevention of collisions of vessels and it is shown that at the locally-independent management for this purpose offered method of forming of flexible strategies of divergence, methods of nonlinear integral invariance and theories of optimum discrete processes. Formalization is also produced cooperation of vessels in the situations of dangerous rapprochement and choice of strategy of divergence. Strategy of urgent divergence is considered at rapprochement of vessels on small distances and description of process of divergence of vessels and choice of maneuver of divergence is produced in terms of differential antagonistic game. It is shown that for the decision the problem set in the article it is necessary to choose the course of deviation the nearest to programmatic, and which does not belong to none of three impermissible great number of courses of deviation: with the first target, with the second target and with a navigation danger. The condition of the safe passing by the ship of point danger, which foresees superiority of value of distance of the shortest rapprochement with her above the value of maximum possible distance of rapprochement, is resulted, and his analytical expression which allows to expect scope safe courses of deviation of ship. For estimation of danger of rapprochement of ship with a target equalizations of scopes of region of impermissible parameters of motion of ship are resulted. The situation of rapprochement of ship is considered with two targets and the regions of impermissible values of parameters of motion of ship in relation to each of targets are formed. The condition of dangerous rapprochement is formulated. The example of situation of rapprochement of ship with two targets is represented, when there is a point navigation danger in the district of sailing. The graphic reflection of regions of impermissible values of parameters of motion of ship in relation to each of targets is shown, on which the maximum courses of deviation on navigation limitations are also inflicted by the dotted Судноводіння | Shipping & Navigation ISSN 2306-5761 | 2618-0073 30-2020 100 Національний університет «Одеська морська академія» lines. The optimum courses of deviation by the change of course to the right and to the left are certain.

Treatment of uterine fold back by gluttony

The author considers laparotomy to be the best surgical remedy against backward curvature of the uterus. Prior to her, he advises to try treatment with pessaries, especially in cases where the appendages are healthy and the uterus is mobile, small in size and the disease is not acute. In cases of complications with metritis, perineal rupture, you should first heal them and then apply a pessary. Analyzing the operative methods of retroflexion treatment, the author divides them into the following categories: vaginal surgery, Alexandr's surgery, hystropexia and laparotomy.
