[Testing problems regarding narcotic substances in hair analysis]. / O problemakh testirovaniia na narkoticheskie veshchestva po analizu volos.

The authors discuss legal, ethic, and technological problems associated with introduction of drug testing by analysis of hair in Russia. There are sufficiently reliable methods of hair analysis, but lack of legal basis and poor equipment of forensic chemical departments impede the introduction and wide use of these methods in Russia. The authors propose certification of the best equipped departments and render them the legal status of regional centers for tests for narcotics and psychotropic agents.

[The forensic medical assessment of the bone damages to skeletons from a group burial in the environs of Yekaterinburg]. / Sudebno-meditsinskaia otsenka povrezhdenii kostei skeletov iz gruppovogo zakhoroneniia v okrestnostiakh Ekaterinburga.

Results of comprehensive expert evaluation of bone remains found at the place of burial made 80 years ago are presented. Injuries inflicted by gunshots, mechanical, chemical, and other factors are classified. Diagnostic criteria for reconstruction of circumstances of death and burial of the Romanov family and subjects in their attendance are defined.

[The diagnosis of the mechanisms of bone tissue destruction from the surface of the break]. / Diagnostika mekhanizmov razrusheniia kostnoi tkani po poverkhnosti izloma.

Data on bone tissue fractography are summarized and systematized. Possibilities of a microscopic fractography method in analysis of skeletal bone fractures in order to determine conditions of traumatic exposure were shown. Destruction of bone tissue is considered from the point of view of fragile and tough destruction using as a model solid body with crack at the top of which deformations of detachment, lateral and longitudinal shifts are acting. Morphologic features for different types of destruction were singled out. Use of these features may help to determine character and type of deformation at concrete areas of fracture during all destruction process.

[The methodological aspects of establishing the time of death]. / Metodologicheskie aspekty ustanovleniia davnosti nastupleniia smerti.

Methodological analysis of essence of problem concerning postmortem interval estimation is given. The authors present the most promising ways of scientific research on this problem and possibilities of practical use of results of scientific research. The general methods of postmortem interval estimation including wired-in analogy (criterial) method and methods of modelling postmortal processes (mathematical and physical) are analysed. Graph of logical structures of modes of postmortem interval estimation and means of their realization is given.

[Fractography of the long tubular bones of the lower extremities in trauma by blunt objects]. / Fraktografiia dlinnykh trubchatykh kostei nizhnikh konechnostei pri travme tupymi predmetami.

New data on micromorphological signs of fracture of long tubular bones in normal distribution and transformation of deforming forces are presented. Fractographic signs of bone for each destructive stage, signs of repeated trauma are singled out. Interrelationship between bone microstructure and conditions of its destruction is stated.
