Seals and stamps, as well as their impressions, have been the objects of forensic identification for many decades, and although there are legal grounds for refusing to use seals by economic entities at present, documents are still certified with seal impressions. Recently, a great number of documents have been received for examination to address the issues as to the time period for document production. The forensic task on establishing the time period for document production is relevant.
Only in the 80-s of the last century research regarding the possibilities of determining the time period for document production by impressions made by seals (stamps) clichés, produced with the help of vulcanizing rubber using movable types or typewriter composition was initiated. Over the past forty years, cliché manufacturing processes and the materials used in this process have significantly changed. At present, clichés produced with the use of new technologies are widespread, namely: laser engraving of rubber made by using photopolymer technology or flash technology. Changes in the technology of making clichés, production of new materials have led to the emergence of features that are formed in the cliché while its using. These features are displayed in the impressions of seals and stamps clichés. The article outlines the characteristic features of seals (stamps )clichés, considers the conditions for the occurrence of features in the process of their use, shows the evolution of their change, outlines the time periods for the existence of features, defines the criteria for attributing features to identically significant temporal features of the cliché. The mentioned temporal features appearing in the cliché of seals and stamps in general (taking into account handles) and in impressions over a certain period of time, allows to determine the time period of applying the impression on a document. In this case, free samples of impressions that have been made over the time period of examination and meet certain requirements should be provided for comparative analysis.
For the categorical conclusion that the impression of a seal (stamp) was made in a specific period of time, it is needed to establish a set of persistent individual features that appeared in the studied impression and its copy over a certain period of time.Визначення періоду часу виготовлення документа є актуальним завданням технічної експертизи документів.

Isotope shifts of the 2-2 transition in B-like ions
Isotope shifts of the 2-2 transition in B-like ions are
evaluated for a wide range of the nuclear charge number: Z=8-92. The
calculations of the relativistic nuclear recoil and nuclear size effects are
performed using a large scale configuration-interaction Dirac-Fock-Sturm
method. The corresponding QED corrections are also taken into account. The
results of the calculations are compared with the theoretical values obtained
with other methods. The accuracy of the isotope shifts of the
2-2 transition in B-like ions is significantly improved.Comment: arXiv admin note: text overlap with arXiv:1410.707
Relativistic calculations of the isotope shifts in highly charged Li-like ions
Relativistic calculations of the isotope shifts of energy levels in highly
charged Li-like ions are performed. The nuclear recoil (mass shift)
contributions are calculated by merging the perturbative and large-scale
configuration-interaction Dirac-Fock-Sturm (CI-DFS) methods. The nuclear size
(field shift) contributions are evaluated by the CI-DFS method including the
electron-correlation, Breit, and QED corrections. The nuclear deformation and
nuclear polarization corrections to the isotope shifts in Li-like neodymium,
thorium, and uranium are also considered. The results of the calculations are
compared with the theoretical values obtained with other methods.Comment: 28 page

The basic ways of manufacturing of the seals and stamps cliche which prints meet now on documents are considered. The seals (stamps) concern them made: 1) by an engraving directly on metal (thuspainting substance is not used, and on a paper the relief print is formed); 2) by vulcanization of rubber with use of type-setting fonts or linotype sets; 3) with use regilon and termoflon; 4) way of vulcanization of rubber from the matrixes received by milling; 5) with use of microporous rubber in the block with a stamp pillow. The resulted ways of manufacturing of the seals cliche are labour-consuming, include many stages and have not received distribution to Ukraine. Today in Ukraine the most widespread are such ways of manufacturing of the seals and stamps cliche: a photopolymeric way; a way of a laser engraving of rubber; manufacturing of the seals and stamps from microporous rubber on flesh-technology. The photopolymeric printing form receive by image copying on a layer of a material which fotopolymerize and forms the image, with the subsequent washing away not polymerizing sites. In a way of a laser engraving of rubber energy is applied to formation of relief images on a cliche powerful, is thin the focused laser beam. Manufacturing of the seals and stamps with flesh-technology use is based on reproduction of the image of a breadboard model on special microporous thermosensitive rubber at its roasting. Microporous rubber becomes impregnated with a stamp paint which by pressing a cliche through an open time is squeezed out on a paper and forms a print. Comparison of manufacturing ways of the seals and stamps cliche allows to draw a conclusion that the photopolymeric way is today the most simple, cheap, fast and accessible.Розглянуто основні способи виготовлення кліше печаток і штампів, відтиски яких зустрічаються сьогодні на документах.

A strange non-local monotone operator arising in the homogenization of a diffusion equatio with dynamic nonlinear boundary conditions on particles of critical size and arbitrary shape
We characterize the homogenization limit of the solution of a Poisson equation in a bounded domain, either periodically perforated or containing a set of asymmetric periodical small particles and on the boundaries of these particles a nonlinear dynamic boundary condition holds involving a Hölder nonlinear [sigma](u). We consider the case in which the diameter of the perforations (or the diameter of particles) is critical in terms of the period of the structure. As in many other cases concerning critical size, a "strange" nonlinear term arises in the homogenized equation. For this case of asymmetric critical particles we prove that the effective equation is a semilinear elliptic equation in which the time arises as a parameter and the nonlinear expression is given in terms of a nonlocal operator H which is monotone and Lipschitz continuous on L2(0;T), independently of the regularity of [sigma]
