The determination of sex drawing on the differences in certain dimensions of skeletal bones constitutes one of the main tasks of forensic medicine and osteology.Aim. To develop informative and ...reliable science-based diagnostic criteria for sex determination (as part of personal identification in forensic medicine) on the basis of a number of parameters associated with the scapula, drawing on statistically calculated formulae.Material and methods. The study included 108 corpses of people, who died aged 19 to 99 years in the Central region of Russia in 2016 from cardiovascular diseases, acute poisoning with ethanol and/or drugs, as well as from concomitant mechanical injuries to the body. Morphometric, osteometric and statistical methods of research were employed, along with a mathematical one when using a software package for the statistical analysis of the material.Results. New formulae have been obtained that allow sex to be determined on the basis of individual parameters associated with the scapula.Conclusion. The obtained data will help reliably reduce the number of osteometric studies, shifting focus to the collection of specific material, which will decrease economic and time expenditures on conducting the morphometric studies of bones in general, as well as dramatically increase the evidentiary significance of the examination in criminal proceedings.
The sex identification by the various parameters of the bones is one of the most important tasks of osteology and forensic science.Objectives. To develope evidence-based diagnostic criteria for ...determining a person’s gender in the context of forensic identification of the person using some parameters of the scapula: the length and width of the acromion process.Material and methods. The study material was 108 corpses aged 19 to 99 years old from the central region of Russia examined in 2016. The causes of death were diseases of the cardiovascular system, poisoning with ethanol and/or narcotics, complex mechanical trauma. Morphological, morphometric and osteometric methods were used as well as mathematical using statistical software.Results. New criteria were obtained for the sex identification by certain parameters of the scapula. The use of the established data will make it possible to reasonably reduce the range of osteological examinations in favor of a targeted sampling of material which will reduce the time and economic costs of the morphometric bone examinations as well as increase the evidence-based value of expert’s report in criminal procedure.
The objective of the present study was to develop the diagnostic criteria for the medical criminalistic identification of the age group of the subjects based on the age-specific changes in the ...glenoid cavity of scapula. A total of 108 scapulae were available for the examination; they were obtained from the persons at the age between 19 and 99 years who had died from cardiovascular diseases, acute intoxication with ethanol and/or narcotic drugs, and a combined mechanical injury. The morphological, osteometric, and statistical methods were used. The data obtained made it possible to propose the morphological criteria that might be instrumental in decreasing the number of osteological studies and thereby reducing the financial burden associated with morphological studies of the skeleton. Moreover, they are likely to increase the evidentiary value of the expert conclusions.
This paper describes an intelligent adaptive PID controller design procedure. The controller consists of a discrete time PID and an auto-tuning neural network unit. First system identification with a ...nonlinear autoregressive model (NARX) was performed. This model was then used to train the neural PID tuner. A special MATLAB toolbox "SmatPID Toolbox" was developed to automate the process of controller synthesis. The resulting controller was tested in a laboratory coal-gas furnace control system to track specified air flow rates.
The time minimization problem for a mobile controlled robot under state constraints is studied. A numerical solution method based on the Pontryagin maximum principle is proposed. It is known that the ...problem of controlling the mobile robot, as any motion complying with the unicyclic model, belongs to the class of essentially nonregular problems with respect to state constraints. The solution to this problem using the maximum principle is complicated by the fact that there is no formula for the Lagrange multiplier measure. It is not clear how this measure can be expressed in terms of other extremum values and, therefore, it is not clear how the conditions of the maximum principle can be reduced to the corresponding boundary value problem. To overcome this difficulty, a regularization method for the problem based on
-perturbation is proposed. Results of a numerical experiment that demonstrate the continuity of the measure multiplier are presented.
Histological studies of oral cavity mucosa and salivary glands in subjects with chronic alcoholic intoxication revealed changes at the surface of the tongue and in the glandular tissues. Specific ...features of chronic alcoholic intoxication include acinar and ductal hyperplasia, reduction of the adipose tissue mass in salivary gland stroma, predominance of T-lymphocytes in hard palate minor salivary glands and B-lymphocytes in the stroma of labial minor salivary gland, the absence of plasma cells in the stroma of hard palate minor salivary glands and labial mucosa. Leukoplakia, dysplasia, and hyperplasia of the basal epithelial layer of oral cavity mucosa are considered to be the signs of long-term (over 12 months) alcohol consumption.
The mission of korea superconducting tokamak advanced research (KSTAR) Project is to develop a steady-state-capable advanced superconducting tokamak for establishing a scientic and technological ...basis for an attractive fusion reactor. Because the KSTAR mission includes the achievement of a steady-state-capable operation, the use of superconducting coils is an obvious choice for the magnet system. The KSTAR superconducting magnet system consists of 16 TF (toroidal eld) and 14 PF (poloidal eld) coils. Both of the TF and the PF coil systems use internally cooled cable-in-conduit conductors (CICC). The TF coil system provides a eld of 3.5 T at the plasma center, and the PF coil system is able to provide a ux swing of 17 V-sec. The major achievements in the KSTAR magnet system development include the development of CICC, the development of a full-size TF model coil, the development of a background magnetic eld generation coil system, and the construction of a large-scale superconducting magnet and CICC test facility. The TF and The PF coils are being fabricated for the KSTAR completion in the year 2005. KCI Citation Count: 1
This paper presents the qualitative and quantitative characteristics of the morphological manifestations of mechanical strangulation asphyxia in the hanged subjects aged 50 years and the elder ones. ...In addition, the new diagnostic approaches to the expert confirmation of this condition are proposed.
The generation of a magnetic field by convective flows of a conducting fluid in a rotating plane layer is investigated numerically. The problem is considered in the complete three-dimensional ...nonlinear formulation. The sequence of temporal regimes that ensue as the Taylor number Ta increases from 0 (no rotation) to 2000 (the fluid motion is suppressed by rapid rotation) when the other parameters are fixed is studied. The Ta intervals on which bifurcations occur are found, and the breakdown and onset of symmetries in the attractors that arise is investigated.
Several facilities for electron-beam welding have been developed and fabricated at the Budker Institute of Nuclear Physics of the Russian Academy of Sciences. A prototype of the system designed for ...accurate determination of the welded seam position before the welding process and aiming of the electron beam during the welding process is described. For this purpose, the difference in scattering of electrons (and formation of secondary electrons) by the seam and by the surface of the welded workpiece is used, which allows recording the seam image by scanning with a low-current beam. A block diagram of the prototype and basic algorithms of its operation (both tested and proposed for the future) is given. Results of testing and trial operation of the first prototype of the electron-beam welding facility are considered.
