Neurydynamic Features Of Young People With Different Duration Of Vestibular Illusion

The article deals with neurodynamic features in persons with different duration of vestibular illusion of rotation. The review of the literature concludes that the time of arbitrary reactions is ensured by a high level of integrative activity of nerve formations. Also, data on the effect of rotation test on the indicators of vestibulo-sensory reactions of young fighters-all-rounders and on the sensorimotor reactivity and success of flight training are given. The study of sensorimotor reactions revealed that the longest latency periods were in the people with very long vestibular illusion against rotation. Based on the obtained results, it was concluded, that the features of neurodynamic processes in persons with long duration of vestibular illusion of rotation, in the conditions of excitement of the vestibular analyzer, occur to a greater extent by increasing the duration of motor reactions and increasing the time of the reflex respons

The Size of the EU Public Domain

This paper reports results from a large recent study of the public domain in the European Union. Based on a combination of catalogue and survey data our figures for the number of items (and works) in the public domain extend across a variety of media and provide one of the first quantitative estimates of the `size' of the public domain in any jurisdiction

The Value of the EU Public Domain

This paper reports results from a large recent study of the public domain in the European Union. Based on a combination of catalogue, commercial and survey data we present detailed figures both on the prices (and price differences) of in copyright and public domain material and on the usage of that material. Combined with the estimates for the size of the EU public domain presented in the companion paper Pollock and Stepan (2009) our results allow us to provide the first quantitative estimate for the `value' of the public domain (i.e. welfare gains from its existence) in any jurisdiction

A Non-Heme Iron Photocatalyst for Light-Driven Aerobic Oxidation of Methanol

Non-heme (L)FeIIIand (L)FeIII-O-FeIII(L) complexes (L=1,1-di(pyridin-2-yl)-N,N-bis(pyridin-2-ylmethyl)ethan-1-amine) underwent reduction under irradiation to the FeIIstate with concomitant oxidation of methanol to methanal, without the need for a secondary photosensitizer. Spectroscopic and DFT studies support a mechanism in which irradiation results in charge-transfer excitation of a FeIII-μ-O-FeIIIcomplex to generate [(L)FeIV=O]2+(observed transiently during irradiation in acetonitrile), and an equivalent of (L)FeII. Under aerobic conditions, irradiation accelerates reoxidation from the FeIIto the FeIIIstate with O2, thus closing the cycle of methanol oxidation to methanal

Surface Quality of a Work Material Influence on Vibrations in a Cutting Process

The problem of stability in the machining processes is an important task. It is strictly connected with the final quality of a product. In this paper we consider vibrations of a tool-workpiece system in a straight turning process induced by random disturbances and their effect on a product surface. Basing on experimentally obtained system parameters we have done the simulations using one degree of freedom model. The noise has been introduced to the model by the Langevin equation. We have also analyzed the product surface shape and its dependence on the level of noise.Comment: 12 pages, PDF of figures can be obtained from http://archimedes.pol.lublin.pl/~raf/graf/fpic.pd

Generation of GeV protons from 1 PW laser interaction with near critical density targets

The propagation of ultra intense laser pulses through matter is connected with the generation of strong moving magnetic fields in the propagation channel as well as the formation of a thin ion filament along the axis of the channel. Upon exiting the plasma the magnetic field displaces the electrons at the back of the target, generating a quasistatic electric field that accelerates and collimates ions from the filament. Two-dimensional Particle-in-Cell simulations show that a 1 PW laser pulse tightly focused on a near-critical density target is able to accelerate protons up to an energy of 1.3 GeV. Scaling laws and optimal conditions for proton acceleration are established considering the energy depletion of the laser pulse.Comment: 26 pages, 8 figure
