We calculate the transition radiation process ν→νγ at an interface of two media. The neutrinos are taken to be with only standard-model couplings. The medium fulfills the dual purpose of inducing an ...effective neutrino–photon vertex and of modifying the photon dispersion relation. The transition radiation occurs when at least one of those quantities have different values in different media. The neutrino mass is ignored due to its negligible contribution. We present a result for the probability of the transition radiation which is both accurate and analytic. For Eν=1 MeV neutrino crossing polyethylene-vacuum interface the transition radiation probability is about 10−39 and the energy intensity is about 10−34 eV. At the surface of the neutron stars the transition radiation probability may be ∼10−20. Our result is by the three orders of magnitude larger than those of previous calculations.
In this article the work of the Omsk State Medical Academy's department of general surgery is presented. The aim of study was to treat patients with purulent and necrotic wounds of soft tissue by ...using novel hydrodynamical drainaige. In this research 92 patients were taken part, who were inpatient treatment in the department of purulent surgery City Clinical Hospital No 1 named Kabanov A. N. 2010-2013 with purulent and necrotic wounds of soft tissue. Clinical, laboratory, cytological, bacteriological monitoring were conducted over the of wound process during the treatment. Assessment of the reliability of differences between the mean value of clinical indicators was with the calculation of the criterion t--Student, the method chi2 and Criterion Mann-Whitney U. The proposed method of treatment of purulent wound promotes fast the removal of necrotic tissue and pus in the first phase of the wound process that led to more rapid relief of symptoms of intoxication (fever, leukocytosis and common symptoms) at the patients of the basic group. Due to faster removal of necrotic tissue, reduction of common symptoms of intoxication at the patients of the basic group the transition from degenerative and inflammatory type of cystograms to regenerative occurred one or two days before than in the comparison group.
We discuss the transition radiation process \(\nu \to \nu \gamma\) at an interface of two media. The medium fulfills the dual purpose of inducing an effective neutrino-photon vertex and of modifying ...the photon dispersion relation. The transition radiation occurs when at least one of those quantities have different values in different media. We present a result for the probability of the transition radiation which is both accurate and analytic. For \(E_\nu =1\)MeV neutrino crossing polyethylene-vacuum interface the transition radiation probability is about \(10^{-39}\) and the energy intensity (deposition) is about \(10^{-34}\)eV. At the surface of the neutron stars the transition radiation probability may be \(\sim 10^{-20}\). Our result on three orders of magnitude is larger than the results of previous calculations.}

To assess effect of trimetazidine on global and regional systolic and diastolic left ventricular function in patients with combined postinfarction ischemic syndrome.
Patients (n=32) with healed ...myocardial infarction and signs of global systolic (ejection fraction 38,5+/-2,7%) and diastolic (EIA=0,88+/-0,03) left ventricular dysfunction confirmed by Doppler echocardiography.
Regional systolic and diastolic function was assessed by dobutamine stress echocardiography with Doppler tissue imaging before and after 3 months during which the patients received 60 mg/day of trimetazidine.
The segments with hibernating myocardium were found in every patient. These segments along with segments with scars displayed greatest degree of local systolic and diastolic dysfunction and because of their prevalence made significant contribution to the setting of global diastolic dysfunction. Improvement of global diastolic function at rest after trimetazidine was associated with decrease of total number of ischemic segments (from 80 to 67%) especially of those with hibernation (from 61 to 46%).
The hibernating myocardium was most sensitive to metabolic intervention and its presence after myocardial infarction predicted improvement after drug treatment of not only systolic but also diastolic left ventricle dysfunction. Restoration of function of hibernating myocardium turned out to be possible not only after myocardial revascularization but also after medical therapy.
Vegetovascular disorders are obligatory and even leading clinical manifestations of chronic gastrointestinal diseases. Physiotherapy in combination with psychotherapy produce a normalizing effect on ...functional-morphological condition of the gastrointestinal organs, correct alterations in the neuropsychic sphere and autonomic nervous system.
We have investigated two flavor neutrino oscillations in medium with periodic
step electron number density profile. An approximate analytical solution have
been found when the length of the density ...fluctuation is smaller then the
neutrino oscillation length.
We have studied mixing and masses of three left handed Majorana neutrinos in
the model, which assumes exactly degenerate neutrino masses at some "neutrino
unification" scale. Such a simple ...theoretical ansatz naturally leads to
quasidegenerate neutrinos. The neutrino mass splittings induced by
renormalization effects. In the model we found that the parameters of the
neutrino physics (neutrino mass spectrum, mixing angles and CP violation
phases) are strongly intercorrelated to each other. From these correlations we
got strong bounds on the parameters which could be checked in the oscillation
experiments.
