Summary Sex determination of a sufficient certainty is possible using measurements (length and breadth) obtained by X-rays of the human sternum. Body height may be determined by X-rays of the human sternum if a wide dispersion is given. The given relations and formulae are valid only when measuring the sterna of adults.

Summary Measurements of the ethanol flow from the blood into the gastro-intestinal tract revealed an exponential characteristic. The rates of transport were proportional to the differences in concentration. The constants of the exsorption were equal to those of the insorption. The constants of the exsorption were 0.033 min−1 for the stomach, 0.071 min−1 for the small, and 0.019 mm−1 for the large intestine.

The application of the rectal temperature time of death nomogram at the scene of death by 11 authors from 6 lego-medical institutes resulted in a standard deviation of the differences between nomographic and real death time of ± 1.3 h in 46 cases (group I) with met requirements and clearly defined points of contact, nevertheless, including 9 cases with a more progressive cooling (0.5 > Q ≥ 0.2). In cases with a real death time of more than 4 h (N= 26) the standard deviation was ± 1.0 hours corresponding to permissible variation of 95% of ± 2.0 hours. Consequently, the permissible variation of 95% was much smaller than that suggested by the nomogram. The nomographic death time interval did not agree with the real one in 5 cases out of additional 30 cases with recognizably unsure points of contact (group II). Die Anwendung des Rektaltemperatur-Todeszeit-Nomogrammverfahrens am Leichenfundort durch 11 Autoren aus 6 rechtsmedizinischen Instituten ergab in der Fallgruppe I mit erfüllten Voraussetzungen und sicher eingrenzbaren Anknüpfungspunkten (N= 46) eine Standardabweichung der Differenzen zwischen realer und nomographisch bestimmter Todeszeit von ± 1,3 Std; im Kollektiv befanden sich 9 Fälle mit fortgeschrittener Abkühlung (0,5 > Q ≥ 0,2). In den Fällen mit enner Todeszeit von mehr als 4 Std (N= 26) betrug die Standardabweichung ± 1,0 Std, entsprechend 95%-Toleranzgrenzen von ± 2,0 Std. Die 95%-Toleranzgrenzen waren somit enger als auf dem Nomogramm angegeben. An weiteren 30 Fällen mit erkennbar nur unsicheren Anknüpfungspunkten bzw. nicht erfüllten Voraussetzungen (Fallgruppe II) bestand in 5 Fällen keine Überein-stimmung zwischen berechnetem und ermitteltem Zeitbereich des Todeseintritts.

Twenty-one blocks consisting of 20% gelatin were fired at using firearms of the long rifle caliber .22 and .357 Magnum. The frontal area of these blocks was prepared with textile coverings marked with technetium 99m. Two gunshot series of each type were fired at summer, interseasonal, and winter clothing, using different ammunition. The radioactivity of the bombarded blocks was measured by single photon emission computed tomography (SPECT). The results of these gun shot series were presented graphically and compared. Initially (at 2 cm depth), high radioactivity is always detected, which among other things is caused by the defilement of the bullet's surface when shot through the textile covering marked by technetium. The higher radioactivity in the middle and deeper block areas is the result of fiber infiltration. Accordingly, there are greater fiber accumulations in the middle and deeper areas of the path of the bullet. This is the case mainly in thinner clothing (summer). Heavier clothing (autumn, winter) presents a greater obstacle for bullets with greater impact as well. Here, only projectiles having a lesser tendency to deform, as well as a high impact, transport a considerable proportion of textile fibers into the deeper parts of the blocks.

Three car accidents are described in which microtrace analysis was of special significance in the clarification of the seating positions. In all three cases the occupants were under the influence of alcohol. In each case the accident occurred at night and without witnesses. The pattern of injuries in two cases was non-specific. In the first case, no fiber traces were visible to the naked eye; in the other two the fibers were recognizable to the naked eye after close examination. In all three cases, the seating position was ascertained by means of fiber trace analysis.
