On polarization of strange baryons in reactions p + p -> p + Lambda^0 + K^+ and p + p -> p + Sigma^0 + K^+ near thresholds

Polarization properties of strange baryons produced in pp reactions, p + p -> p + Lambda^0 + K^+ and p + p -> p + Sigma^0 + K^$, near thresholds of the final states (p Lambda^0 K^+) and (p Sigma^0 K^+) are analysed relative to polarizations of colliding protons. The cross sections for pp reactions are calculated within the effective Lagrangian approach accounting for strong pp rescattering in the initial state of colliding protons with a dominant contribution of the one-pion exchange and strong final-state interaction of daughter hadrons (Eur. Phys. J. A 9, 425 (2000)).Comment: 11 pages, latex, no figure

Tvorba hadrona u fazi kvark-gluon plazme ultrarelativističih sudara teških iona

We describe the quark gluon plasma (QGP) as a thermalized quark–gluon system, the thermalized QGP phase of QCD. The hadronization of the thermalized QGP phase is given in a way resembling a coalescence model with correlated quarks and antiquarks. The input parameters of the approach are the spatial volumes of the hadronization. We introduce three dimensionless parameters, CM, CB and CB¯ , related to the spatial volumes of the production of low-lying mesons (M), baryons (B) and antibaryons (B). We show that at the temperature ¯ T = 175MeV our predictions for the ratios of multiplicities agree well with the presently available set of hadron ratios measured for various experiments given by the NA44, NA49, NA50 and WA97 Collaborations on Pb+Pb collisions at 158 GeV/nucleon, the NA35 Collaboration on S+S collisions and the NA38 Collaboration on O+U and S+U collisions at 200 GeV/nucleon.Opisujemo kvark-gluon plazmu (QGP) kao ravnotežni sustav kvarkova i gluona, tj. termaliziranu QGP fazu kvantne kromodinamike. Hadronizacija ravnotežne QGP faze opisuje se slično modelu skupljanja s koreliranim kvarkovima i antikvarkovima. Ulazni parametri ovog pristupa su prostorni volumeni hadronizacije. Uvodimo tri bezdimenzijska parametra, CM, CB i CB¯ , vezanih s prostornim volumenima tvorbe lakih mezona (M), bariona (B) i antibariona (B). Pokazujemo da su na temperaturi ¯ T = 175MeV naša predviđanja za omjere višestrukosti u skladu s poznatim skupom omjera hadrona određenim mjerenjima Pb + Pb sudara u eksperimentima NA44, NA49, NA50 i WA97 na 158 GeV/nukleon, NA35 suradnje za S + S sudare i NA38 suradnje za O + U i S + U sudare na 200 GeV/nukleon

Yakut Language in Modern Education System of Republic of Sakha (Yakutia): Actors, Debates, New Challenges

The issues of the Yakut language functioning — the native language of the majority of the Arctic zone of the Republic of Sakha (Yakutia) inhabitants — in the field of education are considered. The authors proceed from the fact that, being one of the key areas (along with such regulated areas of communication as the sphere of official office work, the media, science, etc.) necessary for the preservation and sustainable development of the language, the education sector is able to reflect the current language situation in the region, identify risks and threats to the existence of a particular language. The relevance of the study is due to the fact that we are on the eve of the International Decade of Indigenous Languages (2022—2032), proclaimed by the UN General Assembly. The results of a comparative analysis of the status of the Yakut language de jure and de facto based on the analysis of relevant legislative acts and the results of surveys among residents of Yakutia in 2021 are presented. It is concluded that the analysis carried out makes it possible to judge the negative dynamics, which manifests itself in a moderate but continuous decrease in linguistic competence among native speakers of the languages of the peoples of the Russian Federation. It is noted that this situation at the present stage is noticeable only to experts and philologists, but it poses a certain threat to the existence of the language in the long term

Genes of pathogenicity of Enterococcus bacteria isolated from the vaginal biotope of women with chronic endometritis and reproductive disorders

The microflora of the vagina plays an important role and should be regarded as a kind of ecological system that reacts to any changes in the state of the woman's body. Clinically expressed genital infections are etiologically associated with opportunistic microorganisms. In the pathogenesis of dysbiosis, an important role is played not only by quantitative and qualitative changes in microflora, but also by the "pathogenic potential" of microorganisms. The aim of the work was to reveal genes of pathogenicity in strains of Enterococci of the vaginal biotope of women of the studied groups. The study involved 102 women with reproductive disorders. The main group - women with chronic endometritis (CE), (n = 63), mean age - 31.0 ± 5.3. The diagnosis of chronic endometritis was made on the basis of morphological signs of histological examination of vacuum suction biopsy. The comparison group consisted of 39 women, representative by age; in this group the diagnosis was not confirmed by the results of the histological study of the endometrium. It has been established that enterococcal strains isolated only in women with reproductive disorders and chronic endometritis are a reservoir of genetic determinants of pathogenicity factors (efaA and asa1 (12.5 %) and sprE (37.5 %))
