conclusions trichotillomania may also be seen in preschool-aged children and may be associated with separation anxiety disorder. improper and late treatment can be associated with a worsening of the disorder. case presentation a 4.5-year-old girl without any psychiatric disorders in the family. she was cared for by her mother, and the child had a history of separation anxiety. after detection o...

Experiments on patients with Parkinsonism showed that the damping factor was lowered, so that, a tension stimulus being without supraspinal effect, oscillation occurred.

We consider the phase transition of a string with tension ε1 to a string with a smaller tension ε2. The transition proceeds through quantum tunneling, and we calculate in arbitrary number of dimensions the pre-exponential factor multiplying the leading semiclassical exponential expression for the rate of the process. At ε2 = 0 the found formula for the decay rate also describes a break up of a ...

We consider the phase transition of a string with tension ε1 to a string with a smaller tension ε2 at finite temperature. For sufficiently small temperatures the transition proceeds through thermally catalyzed quantum tunneling, and we calculate in arbitrary number of dimensions the thermal catalysis factor. At ε2 = 0 the found formula for the decay rate also describes a break up of a metastabl...

Rideability, i.e. the ease and comfort with which a horse can be ridden, is considered to be one of the most important traits in riding horses. However, at present rideability is evaluated rather subjectively in breeding horse performance tests. The aim of the present study was to evaluate the role horse behaviour as well as degree and quality of rein tension might play in judges' evaluation of...

Tension is a principal force experienced by skin and serves a critical role in growth and development. Optimal tension application regimens may be an important component for skin tissue engineering and dermatogenesis. In this study, we designed and tested a novel servo-controlled skin-stretching device to apply predetermined tension and waveforms in mice. The effects of static and cyclical stre...

mecum, and the cutting is due to constriction in this ring, and the constriction to a change in surface tension, the work invo ved would require a minimum reduction along the inner surface of the ring of at least 383 dynes per centimeter. The bulk of evidence at hand seems to indicate that the paramecia are divided by the approach of two pseudopods and not by the constriction of a ring. To acco...

Fiber winding tension is an important factor in the molding techniques of composite material which influences the quality of winding product directly, and the tension control is a key technique in fiber winding techniques. This paper introduces a closed-loop tension control system with the programmable logic controller (PLC) with function modules as its control kernel, the alternating current (...
