title: [Specific regular features of trace formation depending on the properties of the trace-receptive surface and the height of blood droplet fall].
abstract: The objective of the present work was to study the morphological characteristics of blood stains resulting from the static fall of blood droplets onto a sloping stain-receptive surface depending on its properties and the height of fall. The blood droplets were allowed to fall down from a specially designed device onto the sloping surfaces at an angle of 45 degrees from the height varying from 5 to 200 cm. The receptive surfaces had different absorbing capacity (non-absorbing, moderately absorbing, and well-absorbing surfaces). The analysis of the blood stains thus obtained showed that they differed in the size, shape, and morphological features depending on the height of fall of the droplets, the absorbing properties of the trace-receptive surfaces, and the angle of incidence of blood droplets. The results of the study can be used to improve the quality of forensic medical expertise of the surfaces soiled with blood stains.
