Comparing Etymological Characteristics of Plant Naming in Yakut, Even, and Evenk Languages

This article considers issues of language contacts between Yakut, Even, and Evenk people through an analysis of plant vocabulary. We define etymological characteristics of fixed lexical units that denote plant names and present results of a comparative analysis of plant naming in these three languages, with emphasis on lexical parallels and structural types in designating plant names. To our knowledge, this is the first research to undertake a comparative study of plant naming in the Yakut and Tungusic languages (Even and Evenk) with consideration of the methods of their formation. The study is highly relevant because of the unique contribution of plant-world vocabulary in helping to clarify peculiarities of native speakers’ natural environments. Our results show that, based on lexical units with stable semantic meaning, the Evenk language is in the closest position vis-à-vis Yakut. There are 16 names in Yakut of plants and four of common names of herbs that grow on the territory of the Republic of Sakha (Yakutia) and have borrowed names in Evenk and Even. Twenty-eight names have lexical parallels in Evenk (including variations) and two in Even.Cet article se penche sur la question des contacts linguistiques entre les Yakoutes, les Évènes et les Evenkis au moyen de l’analyse du vocabulaire des plantes. Nous définissons les caractéristiques étymologiques d’unités lexicales fixes dénotant les noms de plantes et présentons les résultats de l’analyse comparative de la nomenclature de plantes dans ces trois langues, en mettant l’accent sur les parallèles lexicaux et les types structuraux de la désignation des noms de plantes. À notre connaissance, il s’agit de la première recherche à entreprendre l’étude comparative de la nomenclature botanique en langues yakoute et toungouse (évène et evenki) tout en tenant compte de leurs méthodes de formation. Cette étude est d’une grande pertinence, car l’apport unique du vocabulaire des plantes aide à expliquer les particularités des milieux naturels des locuteurs natifs. Selon nos résultats, fondés sur les unités lexicales dotées de significations sémantiques stables, l’evenki est la langue la plus proche du yakoute. En yakoute, il y a 16 noms de plantes et quatre noms communs d’herbes dans le territoire de la république de Sakha (Yakoutie) dont les noms ont été empruntés à l’evenki et à l’évène. Vingt-huit noms ont des parallèles lexicaux en evenki (variantes y comprises), et deux en évène

The nexus of soil radon and hydrogen dynamics and seismicity of the northern flank of the Kuril-Kamchatka subduction zone

The comparison of kinematics and dynamic parameters of radon and molecular hydrogen concentration in subsoil air on the stations network at the Petropavlovsk-Kamchatsky geodynamic proving ground with seismicity of the northern flank of the Kuril-Kamchatka subduction zone was fulfilled in the period from July till August 2004. On the basis of correlation analysis of the regional seismicity and variations of radon flux density calculated using the data of gas-discharge counters of STS-6 type and SSNTDs it was shown that the radon mass transfer abnormal variations are conditioned by both regional seismicity in total and the subduction zone of proving ground. The azimuths of «geodeformation waves» coming to the registration points are calculated during clearly expressed anomaly beginnings, which coincide with directions to earthquake epicenters taking place at the same time. The geochemical anomalies recorded are presumptively deformative by nature and can be conditioned by processes of «quasi-viscous» flow of the lithosphere during rearrangement of tectonic stress fields of the subduction zone. The short-term (predicted time Τ <14 days) precursor of the earthquakes swarm was revealed in hydrogen dynamics on August, 4-5 (four earthquakes had M≥5.3 and epicentral distance about 130 km from the Paratunka base station)

Design of Pre-Dumping Ring Spin Rotator with a Possibility of Helicity Switching for Polarized Positrons at the ILC

The use of polarized beams enhance the possibility of the precision measurements at the International Linear Collider (ILC). In order to preserve the degree of polarization during beam transport spin rotators are included in the current TDR ILC Lattice. In this report some advantages of using a combined spin rotator/spin flipper are discussed. A few possible lattice designs of spin flipper developed at DESY in 2012 are presented.Comment: Talk presented at the International Workshop on Future Linear Colliders (LCWS15), Whistler, Canada, 2-6 November 201

Revision of Cerinomyces (Dacrymycetes, Basidiomycota) with notes on morphologically and historically related taxa

Publisher Copyright: © 2021 The AuthorsCerinomyces (Dacrymycetes, Basidiomycota) is a genus traditionally defined by corticioid basidiocarps, in contrast to the rest of the class, which is characterized by gelatinous ones. In the traditional circumscription the genus is polyphyletic, and the monotypic family Cerinomycetaceae is paraphyletic. Aiming for a more concise delimitation, we revise Cerinomyces s.l. with a novel phylogeny based on sequences of nrDNA (SSU, ITS, LSU) and protein-coding genes (RPB1, RPB2, TEF1-α). We establish that monophyletic Cerinomyces s.s. is best characterized not by the corticioid morphology, but by a combination of traits: hyphal clamps, predominantly aseptate thin-walled basidiospores, and low content of carotenoid pigments. In our updated definition, Cerinomyces s.s. encompasses five well-supported phylogenetic clades divided into two morphological groups: (i-iii) taxa with arid corticioid basidiocarps, including the generic type C. pallidus; and (iv-v) newly introduced members with gelatinous basidiocarps, like Dacrymyces enatus and D. tortus. The remaining corticioid species of Cerinomyces s.l. are morphologically distinct and belong to the Dacrymycetaceae: our analysis places the carotenoid-rich Cerinomyces canadensis close to Femsjonia, and we transfer the clamps-lacking C. grandinioides group to Dacrymyces. In addition, we address genera related to Cerinomyces s.l. historically and morphologically, such as Ceracea, Dacryonaema and Unilacryma. Overall, we describe twenty-four new species and propose nine new combinations in both Cerinomycetaceae and Dacrymycetaceae.Peer reviewe

«Привлечённый библиотекарь» (embedded librarian): литературный обзор

The article  is based  on  the  methodology of selecting publications for reviewing  proposed  earlier  (see  Scientific  and  Technical  Journal.  2022.  No. 11. Р. 56–82). This methodology enables  to  systematize the  process  of publication selection with the results  cited in the protocol. The “embedded librarianship” concept definition  is based on the activity component. Three subject vectors are high-lighted  in visualization  of the  study  subject  scope,  namely, librarians  in medical environment, librarians  in education, and librarians  involved in scientific research. The conventional embedded librarian’s profile is formulated, with the professional functionality  described  and environment characterized. The specialist’s basic competences are information  literacy and client orientation. Being complemented with  unique  competences,  the  basic  skills  enable   the  embedded  librarians   to transfer  from the  status  of resource-users agent  to  that  of research  group  full-fledged  participant.  The author  suggests her adapted translations of the  concept names.“Embedded  librarianship”  has  substantial  potential  within  the  framework of scientific  research  information  support  in the  form of reviews,  which explains why the reviews are seen  as an informative  source, in particular  for the librarians developing  library programs  with “embedded” information  services.  The concept may be used for organizing services in research  and academic libraries.Представленная   статья  написана  с  применением   предложенной ранее методики подбора публикаций для обзоров (см. «Научные и технические библиотеки». 2022.  № 11.  С. 56–82) Методологический подход  позволил  систематизировать  процесс  отбора  публикаций,  результаты которого приведены в протоколе.

FOXP3, IL2R, CD8A and RORγ gene expression in peripheral blood leukocytes of healthy people and patients with arterial hypertension

Impaired balance of T regulatory and T effector lymphocytes has recently been considered as an important pathogenetic link in arterial hypertension (AH). There are, however, contradictory literature data about contents of these cells in the patients with hypertension, or obtained in experimental animal models of induced hypertension. Most results about changed patterns of immune cells in cardiovascular diseases were obtained by means of flow cytometry. There are also some works on expression of genes encoding surface and cytoplasmic differentiation antigens of immune cells in the patients with cardiovascular pathologies. These results coincide with the data obtained with flow cytometric techniques. Purpose of the present study was to analyze of the levels of gene transcripts encoding differentiation markers of regulatory (FOXP3, IL2R) T cells, effector T subpopulations (T helpers 17 (RORγ), and CD8 lymphocytes (CD8A) in healthy subjects and the patients with arterial hypertension (stages I-II). We examined healthy individuals (40 people, 20 men and 20 women), 27 patients with hypertension who did not receive antihypertensive therapy (14 men and 13 women), 26 hypertensive patients taking β-adrenergic receptor blockers (metoprolol or bisoprolol), including 12 men and 14 women. The relative levels of transcripts in peripheral blood leukocytes were assessed by real-time RT-PCR. It was shown that the transcriptional activity of FOXP3, IL2R, RORγ, and CD8A genes in peripheral blood leukocytes of the diseased people was significantly higher than in healthy individuals (p &lt; 0.01). This finding may indicate an increased number of circulating T regulatory lymphocytes, CD8+ cells and T helpers 17 in hypertensive patients, and activation of T cell immunity in these patients. There were no statistically significant gender differences in FOXP3, IL2R, RORγ and CD8A gene expression in leukocytes, both in the group of healthy people and in hypertensive patients. The patients receiving cardioselective β-adrenergic receptor blockers (metoprolol and bisoprolol) exhibited lower expression of these genes, thus, probably, indicating antiinflammatory and immunomodulatory properties of these drugs

Grain-structure development in heavily cold-rolled alpha-titanium

High-resolution electron back-scatter diffraction (EBSD) analysis was employed to establish mircostructure evolution in heavily cold-rolled alpha-titanium. After thickness reductions of 75% to 96%, significant microstructure and texture changes were documented. The surface area of high-angle grain boundaries was almost tripled, thus giving rise to an ultra-fine microstructure with a mean grain size of 0.6 μm. Moreover, orientation spread around typical ‘split-basal’ rolling texture substantially increased. These effects were suggested to be related to the enhancement of pyramidal 〈c+a〉 slip.

Experimental determination of the adhesive characteristics of the “elementary fiber-epoxy matrix” system

The paper considers the method of testing the elementary fiber-polymer matrix system. Results of determining the following adhesive characteristics are provided: apparent and local adhesive strength, start and end in the adhesive destruction of the fiber-matrix joint under study. Basalt fiber and epoxy matrix based on the epoxy resin and amine hardener are considered as the study objects. Influence of the samples geometric characteristics on their adhesive characteristics is established. The paper shows that at the depth of the elementary fiber emersion in the polymer matrix equal to 200 µm, the scatter of all determined adhesive characteristics is significantly reduced
