Developing Translation Competence in Thermal Power Engineering Students
An engineering graduate today should be able to apply a variety of professional and the so-called deep learning competences including communication and translation competence. The paper gives a review of the notion of translation competence and presents key pre-requisites and creative tasks that enable thermal power engineering students of the National Research Tomsk Polytechnic University, Russia, develop and master translation competence
Features of water chemical composition of oligotrophic and eutrophic bogs in the South of the Tomsk region
On the basis of the actual material the analysis of chemical composition of bog waters in the territory of the South of the Tomsk region is carried out. The data on average concentration of macro and trace components, organic matter, pH of bog waters are obtained. Significant distinctions in a chemical composition of surface water for different types of bogs are revealed. The composition and macrostructure of humic acids by the example of eutrophic bogs is studied
Plecotus microdontus (Mammalia: Vespertilionidae), nova vrsta šišmiša iz Austrije
SPITZENBERGER et al. (2001) reported the existence of more than two different genetic clades within long-eared bats in Austria. A genetic analysis of one specimen from the Dalmatian island of Lastovo (Croatia), close to the locus typicus of Plecotus kolombatovici, and an additional morphological analysis of specimens from some other Dalmatian islands revealed the fact that in contrast to the previous interpretation, clade 2 in SPITZENBERGER et al. (2001) does not represent P. kolombatovici, which is a separate species related to P. austriacus. Clade 2 has to be considered a new species, P. microdontus n. sp., which is the sister group of P. auritus. It is distinguishable in external, skull and teeth characters from other European Plecotus species. It is known from the Alps between Liguria and Slovenia.SPITZENBERGER et al. (2001) su objavili da u Austriji postoji više od dvije genetički različite grupe dugouhih šišmiša. Genetička analiza jednog primjerka šišmiša ove skupine s dalmatinskog otoka Lastova (Hrvatska) koji je neposredno uz locus typicus vrste Plecotus kolombatovici, te dodatna morfološka analiza primjeraka s drugih dalmatinskih otoka, pokazali su suprotno prethodnom objašnjenju da grupa 2 u SPITZENBERGER et al. (2001) ne predstavlja vrstu P. kolombatovici, koja je odijeljena vrsta srodna s P. austriacus. Za navedenu grupu 2 iz tog rada smatramo da predstavlja za znanost novu vrstu, P. microdontus n. sp., koja pripada grupi P. auritus. Ona se od ostalih europskih vrsta roda Plecotus razlikuje u vanjskoj morfologiji, značajkama lubanje i zubiju. Poznata je iz Alpa u području između Ligurije i Slovenije
Morfologija i sekvence mitohondrijske DNK pokazuju da su Plecotus alpinus Kiefer & Veith, 2002 i Plecotus microdontus Spitzenberger, 2002 sinonimi Plecotus macrobullaris Kuzjakin, 1965
Genetic and morphological analyses of long-eared bats from Northern Ossetia and other Caucasian localities revealed that the sister clade of Plecotus auritus discovered in the Eastern Alps (SPITZENBERGER et al., 2001) and described as a new species by Spitzenberger (SPITZENBERGER et al., 2002) (Plecotus microdontus) and by KIEFER & VEITH (2002) (Plecotus alpinus) is conspecific with Plecotus macrobullaris Kuzyakin, 1965, described as a subspecies of P. auritus, from the vicinity of Vladikavkaz. The valid name for this species therefore is Plecotus macrobullaris. P. macrobullaris also occurs in central and eastern Turkey. Morphological as well as genetic analyses differentiate between an eastern and a western group within P. macrobullaris. From a morphological comparison of specimens of P. macrobullaris with the type specimens of Plecotus wardi from Kashmir we conclude that macrobullaris is not conspecific with wardi.Genetske i morfološke analize dugouhih šišmiša iz Sjeverne Osetije i drugih kavkaskih lokaliteta otkrile su da je sestrinska grupa vrste Plecotus auritus, otkrivena u Istočnim Alpama (SPITZENBERGER et al., 2001) i opisana kao nova vrsta od Spitzenberger (SPITZENBERGER et al., 2002) (Plecotus microdontus) i KIEFER & VEITH (2002) (Plecotus alpinus), konspecifična s vrstom Plecotus macrobullaris Kuzyakin, 1965, opisanom kao podvrsta od P. auritus iz blizine Vladikavkaza. Zato je validno ime ove vrste Plecotus macrobullaris. P. macrobullaris se također javlja u središnjoj i istočnoj Turskoj. Morfološke i genetičke analize pokazuju razliku istočne i zapadne grupe unutar P. macrobullaris. Iz morfološke usporedbe primjeraka P. macrobullaris s tipskim primjercima Plecotus wardi iz Kašmira zaključujemo da macrobullaris nije konspecifičan s wardi

The blazar S5 0014+813: a real or apparent monster?
A strong hard X-ray luminosity from a blazar flags the presence of a very
powerful jet. If the jet power is in turn related to the mass accretion rate,
the most luminous hard X-ray blazars should pinpoint the largest accretion
rates, and therefore the largest black hole masses. These ideas are confirmed
by the Swift satellite observations of the blazar S5 0014+813, at the redshift
z=3.366. Swift detected this source with all its three instruments, from the
optical to the hard X-rays. Through the construction of its spectral energy
distribution we are confident that its optical-UV emission is thermal in
origin. Associating it to the emission of a standard optically thick
geometrically thin accretion disk, we find a black hole mass of 40 billion
solar masses, radiating at 40% the Eddington value. The derived mass is among
the largest ever found. Super-Eddington slim disks or thick disks with the
presence of a collimating funnel can in principle reduce the black hole mass
estimate, but tends to produce spectra bluer than observed.Comment: 5 pages, 2 figures, accepted for publication as a letter in MNRAS

Surgical treatment for non-parasitic liver cysts improves quality of life
BACKGROUND&PURPOSE: Liver cysts occur frequently. Most are harmless, however some carry a significant patient burden. Optimizing treatment strategy is complicated as needs differ between patients. The current study assesses the effect of surgery on quality of life (QoL) of patients with non-parasitic liver cysts. METHODS: A retrospective cohort study of all patients who underwent surgery for non-parasitic liver cysts in three major Dutch medical centers from 1993 to 2017. Patient characteristics and surgery related variables were collected from the electronic patient file. QoL was measured before and after surgery using the EORTC QLQ-C30. Summary scores (SumSc) were calculated and compared to reference values of the general population. Multivariate analysis using logistic regression was performed for identifying outcome related factors. Increase of ≥ 10% in SumSc was defined as clinically relevant. MAIN FINDINGS: Eighty-eight of 132 eligible patients (67%) completed two QoL assessments. Respondents demonstrated significant improvement in the global health status, on all 5 functional scales (all p ≤ 0.005), on all 9 symptom scales after surgery (all p < 0.05), and on SumSc (p < 0.001) to levels similar or better than the general population. Patients with complications demonstrated a significant QoL gain (p < 0.05), and reported a similar postoperative status compared to patients without complications (p = 0.74). QoL gain for patients who underwent open and laparoscopic cyst fenestration were similar (p = 0.08). Multivariate analysis of SumSc found mechanical complaints as significant factor for ≥ 10% SumSc increase (OR 0.11, 95% CI (0.02-0.55). CONCLUSIONS: Surgery is a safe and effective strategy to significantly improve QoL in patients with symptomatic liver cysts
The Race Between Stars and Quasars in Reionizing Cosmic Hydrogen
The cosmological background of ionizing radiation has been dominated by
quasars once the Universe aged by ~2 billion years. At earlier times (redshifts
z>3), the observed abundance of bright quasars declined sharply, implying that
cosmic hydrogen was reionized by stars instead. Here, we explain the physical
origin of the transition between the dominance of stars and quasars as a
generic feature of structure formation in the concordance LCDM cosmology. At
early times, the fraction of baryons in galaxies grows faster than the maximum
(Eddington-limited) growth rate possible for quasars. As a result, quasars were
not able to catch up with the rapid early growth of stellar mass in their host
galaxies.Comment: 5 pages, 1 figure, Accepted for publication in JCA
