Проблема номинации и обозначения в языке и речи: сопоставительный аспект
There is a correlation between the sense of lingual sign (the means of nomination) and the sense of speech sign (the means of designation). The nature of this correlation is in the possibility of using lingual sign for the designation of the referent. It relies on the coincidence of signification and designation features.Между значением языкового знака как средства номинации и значением речевого знака как средства обозначения существует определенная связь. Она заключается в возможности использования языкового знака для речевого обозначения референта и основывается на совпадении сигнификативных и десигнативных признаков
Перевод: фрейм - единица мысли и речи
The peculiarity of this article is the new realizing of a unit of translation concept in the field of translating and interpreting activity. There is an attempt to answer the question: what is to be considered as a unit of translation in general and in the linguistic reason in particular? We introduce our views on the balance between a unit of a thought and a unit of translation when we use the technology of the stereotype interaction. For a translator a unit of a thought as a portion of realized information might be a unit for translation. So, we conclude: a frame of knowledge might be a unit of a thought and a unit of translation simultaneously and consequently.Основная идея статьи - концепция нового понимания единицы перевода в области устной и письменной переводческой деятельности. Осуществляется попытка определить единицу перевода в общем смысловом и лингвистическом смыслах. Технология стереотипных итераций создает баланс речемыслительного процесса. В ситуации переводчика понятая порция информации может быть минимальным объектом перевода. Фрейм как лингвистическое явление одновременно соизмеряет оба аспекта речемыслительного процесса

According to the simulation results, the technological aspects of the use of the composite are given
Correlation of Beam Electron and LED Signal Losses under Irradiation and Long-term Recovery of Lead Tungstate Crystals
Radiation damage in lead tungstate crystals reduces their transparency. The
calibration that relates the amount of light detected in such crystals to
incident energy of photons or electrons is of paramount importance to
maintaining the energy resolution the detection system. We report on tests of
lead tungstate crystals, read out by photomultiplier tubes, exposed to
irradiation by monoenergetic electron or pion beams. The beam electrons
themselves were used to measure the scintillation light output, and a blue
light emitting diode (LED) was used to track variations of crystals
transparency. We report on the correlation of the LED measurement with
radiation damage by the beams and also show that it can accurately monitor the
crystals recovery from such damage.Comment: 9 pages, 6 figures, LaTeX2
Comparison of Radiation Damage in Lead Tungstate Crystals under Pion and Gamma Irradiation
Studies of the radiation hardness of lead tungstate crystals produced by the
Bogoroditsk Techno-Chemical Plant in Russia and the Shanghai Institute of
Ceramics in China have been carried out at IHEP, Protvino. The crystals were
irradiated by a 40-GeV pion beam. After full recovery, the same crystals were
irradiated using a -ray source. The dose rate profiles along
the crystal length were observed to be quite similar. We compare the effects of
the two types of radiation on the crystals light output.Comment: 10 pages, 8 figures, Latex 2e, 28.04.04 - minor grammatical change
LED Monitoring System for the BTeV Lead Tungstate Crystal Calorimeter Prototype
We report on the performance of a monitoring system for a prototype
calorimeter for the BTeV experiment that uses Lead Tungstate crystals coupled
with photomultiplier tubes. The tests were carried out at the 70 GeV
accelerator complex at Protvino, Russia.Comment: 12 pages, 8 figures, LaTeX2e, revised versio
Design and performance of LED calibration system prototype for the lead tungstate crystal calorimeter
A highly stable monitoring system based on blue and red light emitting diodes
coupled to a distribution network comprised of optical fibers has been
developed for an electromagnetic calorimeter that uses lead tungstate crystals
readout with photomultiplier tubes. We report of the system prototype design
and on the results of laboratory tests. Stability better than 0.1% (r.m.s.) has
been achieved during one week of prototype operation.Comment: 10 pages, 6 figures, LaTeX2
Development of a Momentum Determined Electron Beam in the 1 -45 GeV Range
A beam line for electrons with energies in the range of 1 to 45 GeV, low
contamination of hadrons and muons and high intensity up to 10^6 per
accelerator spill at 27 GeV was setup at U70 accelerator in Protvino, Russia. A
beam tagging system based on drift chambers with 160 micron resolution was able
to measure relative electron beam momentum precisely. The resolution sigma_p p
was 0.13% at 45 GeV where multiple scattering is negligible. This test beam
setup provided the possibility to study properties of lead tungstate crystals
(PbWO_4) for the BTeV experiment at Fermilab.Comment: 12 pages, 8 figures; work done by the BTeV Electromagnetic

Search for Solar Axions Produced by Primakoff Conversion Using Resonant Absorption by Tm Nuclei
The search for resonant absorption of the Primakoff solar axions by
Tm nuclei have been performed. Such an absorption should lead to the
excitation of low-lying nuclear energy level: Tm Tm
Tm (8.41 keV). The Si(Li) detector and Tm target
placed inside the low-background setup were used for that purpose. As a result,
a new restriction on the axion-photon coupling and axion mass was obtained:
(90% c.l.). In model
of hadronic axion this restriction corresponds to the upper limit on axion mass
- 191 eV for 90% c.l.Comment: 6 pages, 5 figures, submitted to Physics Letters
Performance of a fine-sampling electromagnetic calorimeter prototype in the energy range from 1 to 19 GeV
The fine-sampling electromagnetic calorimeter prototype has been
experimentally tested using the 1-19 GeV/c tagged beams of negatively charged
particles at the U70 accelerator at IHEP, Protvino. The energy resolution
measured by electrons is Delta{E}/E=2.8%/\sqrt{E} + 1.3%. The position
resolution for electrons is Delta{x}=3.1 + 15.4/sqrt{E} mm in the center of the
cell. The lateral non-uniformity of the prototype energy response to electrons
and MIPs has turned out to be negligible. Obtained experimental results are in
a good agreement with Monte-Carlo simulations.Comment: Article is prepared for pdflatex using the class elsart. 13 pages, 9
