[Identification of the mode of stab-and-hack wound infliction to the chest based on wound features].

The objective of this study was to obtain morphological characteristics of stab-and-hack wounds inflicted by falling down on the knife blade. A formula is derived based on the results of discrimination analysis that can be used in combination with wound morphological features to differentiate between chest stabbing modes.

[State-of-the-art of mathematical modeling of postmortal thermodynamics for the time of death determination].

Mathematical modeling of postmortal themperature used at present for definition of prescription of the death is shown in the article from a position of theory ofprobablibistic functions. Accuracy of examined techniquies is analized by comparison of modeled temperatures with real, fixed by the authors on a material of 158 expert supervisions. The conclusion about inadmissibility of practical use of some mathematical expressions is made in connection with low accuracy of the mathematical device used in them.

[Using some modern mathematical models of postmortem cooling of the human body for the time of death determination].

Mathematical questions of data errors of modern thermometrical models of postmortem cooling of the human body are considered. The main diagnostic areas used for thermometry are analyzed to minimize these data errors. The authors propose practical recommendations to decrease data errors of determination of prescription of death coming.

[Methodological questions in resolving the problem of determining the time of death].

Presents the modern concept of evaluating the time of death, the philosophy of solving this problem, and approaches to its solution. Analyzes the procedure and choice of correct approach to problem solution from methodological viewpoint and as a problem at the interface of medicine and technology.
