New craniological data on the anthropology of the Turkic population of the steppe-land in the Middle Irtysh territory in the X–XII centuries

The article investigates a cranial series originating from five burials from the right bank of the Irtysh River. The series characterizes the physical appearance of the Turkic (Kimak-Kipchak) population of the steppe part of the Middle Irtysh territory in the X–XII centuries. Craniological complexes in the group studied are predominantly mixed, having both Caucasoid and Mongoloid traits and their racial affinity can be defined as a subdued variant of a combination of South Siberian racial traits. A comparative analysis demonstrated that the Kimak-Kipchak population of the left bank of the Irtysh River with the apparent predominance of Caucasoid features is significantly different from the right bank group. Thus, the anthropology of the Turkic population was heterogeneous and included elements that varied in the degree in which Mongoloid and Caucasoid racial traits were expressed

Evaluation of Microaccelerations on Board the Mir Station Through Optical Star Sensor.

Abstract: Two methods for determining the Mir orbital station attitude motion through optical star sensor are considered. The first method consists in smoothing measurement data by means of cubic splines, the second one is based on smoothing measurements by solutions of a variational problem for Poisson's kinematic equations. The knowledge of the station attitude motion allows to calculate low frequency component of microacceleration at given on board point. Examples of such calculations are given.Note: Research direction:Theoretical and applied problems of mechanic

Microaccelerations on Board the Mir Orbital Station and Quick Analysis of the Gravitational Sensitivity of Convective Heat/Mass Transfer Processes.

Abstract: This paper presents an analysis of the microacceleration phenomena recorded on board the Russian space station Mir. This analysis is based on acceleration measurements collected in September and October of 1995. Acceleration values were obtained by two methods: SAMS measurements, and by calculations based on attitude telemetry information from the Mir station. These calculations allowed estimating a quasi-steady acceleration component. This component was compared with the results of selection of low-frequency component from SAMS measurements. Both methods gave very similar results in some cases after correction of SAMS data. Data preparation techniques for use in problems of computational hydrodynamics are considered. Examples of computer simulation of thermal convection and quick analysis of gravitational sensitivity of convective processes are described.Note: Research direction:Theoretical and applied problems of mechanic
