Placówka Bolesława Prusa jako przyczynek do charakterystyki sąsiedzkich stosunków z Niemcami w Kronikach Bolesława Prusa. Rekonesans

The article analyzes the Polish–German relations described by Bolesław Prus in Kroniki (Chronicles). It raises questions about how the author’s personal beliefs determine the construction of his novel characters. The author has avoided the coloured chauvinism of complaints about the in-creasing number of German colonists coming to the cities and provinces. Prus was aware of threats, but also saw the advantages and strengths of German organizations. Observations of neighbours and international relations were used by Prus mainly for comparisons. Prus’s chronicles and letters are a testimony to the sinusoidal variation of the author’s moods: from intoxication with greatness and modernity to emotional depression.

Computer simulations of colloidal gels: how hindered particle rotation affects structure and rheology

The effects of particle roughness and short-ranged non-central forces on colloidal gels are studied using computer simulations in which bonded particles experience a sinusoidal variation in energy as they rotate.

Experiment and Analysis on Rheology Dynamic Characteristics of Soft Soil

The rheologic action of the soft soil could be accelerated by earthquake the dynamic loading, which induces more geotechnical engineering accidents and geologic disasters. The samples of marine deposit soft soil are collected in xiamen, and the rheologic rate, rheologic acceleration and rheologic strain under the dynamic loading of sinusoidal variation are tested and analyzed by using dynamic-triaxial device, and the influences of dynamic loading frequency and breadth to dynamic characteristics of soft soil are contrasted and analyzed. The research results have important academic signification for us to search rheologic dynamic characteristic of soft soil under dynamic loading.

Roll Rotation Cues Influence Roll Tilt Perception Assayed Using a Somatosensory Technique

We investigated how the nervous system processes ambiguous cues from the otolith organs by measuring roll tilt perception elicited by two motion paradigms. In one paradigm (tilt), eight subjects were sinusoidally tilted in roll with the axis of rotation near ear level. Stimulus frequencies ranged from 0.005 to 0.7 Hz, and the peak amplitude of tilt was 20°. During this paradigm, subjects experienced a sinusoidal variation of interaural gravitational force with a peak of 0.34 g. The second motion paradigm (translation) was designed to yield the same sinusoidal variation in interaural force but did not include a roll canal cue. This was achieved by sinusoidally translating the subjects along their interaural axis. For the 0.7-Hz translation trial, the subjects were simply translated from side to side. A centrifuge was used for the 0.005- to 0.5-Hz translation trials; the subjects were rotated in yaw at 250°/s for 5 min before initiating sinusoidal translations yielding an interaural otolith stimulus composed of both centrifugal and radial acceleration. Using a somatosensory task to measure roll tilt perception, we found substantial differences in tilt perception during the two motion paradigms. Because the primary difference between the two motion paradigms was the presence of roll canal cues during roll tilt trials, these perceptual differences suggest that canal cues influence tilt perception. Specifically, rotational cues provided by the semicircular canals help the CNS resolve ambiguous otolith cues during head tilt, yielding more accurate tilt perception.
