For the first time, five species of fungi of various systematic groups have been noted on the Microbiota decussata in the collection of the Botanical Garden Institute. Some of them were found in Russia for the first time, but are not rare. These findings, in our opinion, clearly demonstrate the poor study of microbiota consorts and the lack of information about substrates and distribution of saprotrophic and pathogenic fungi in Russia.

A manuscript memoir of Hugh Miller (1802–1856), geologist, writer and newspaper editor, is attributed to his son Hugh Miller FGS (1850–1896). It is published here, apparently for the first time. It was written sometime in 1881–1896, more probably 1882–1895. Its intended place of publication is discussed. It is an interesting contribution to Miller biography, written by a family member and providing some new information and anecdotes.

It opens new vista of CN in homogeneous catalysis and offers a successful example of polymeric catalysts in bridging gaps of homo/heterogeneous catalysis.

A case of sooty bark disease and Cytospora poplar canker in the Canton of Geneva In summer 2014, a case of sooty bark disease caused by Cryptostroma corticale on an individual field maple (Acer campestre) and two cases of poplar canker due to Cytospora chrysosperma on Populus x euramericana were identified genetically for the first time on the territory of the Canton of Geneva. In both cases, the trees presented signs of very advanced dieback, accompanied by specific symptoms such as bark peeling and sooty plaques for the maple, and loose twisted bark layers and black colouring of the wood in structural branches of the poplars. Sampling was carried out in the symptomatic areas and components of the fungal flora were isolated in pure cultures in order to identify any pathogenic fungi. The molecular analysis of the rDNA internal transcribed spacer (ITS) sequences made it possible to identify precisely all pure isolates obtained. The results showed a majority presence of C. corticale in the maple tree, and of C. chrysosperma in the two poplars. Both these fungi are little known in Switzerland and Europe, and their presence is maybe associated with changes in the climate.

AbstractOwing to its simple preparation and high oxygen content, nitroformate [−C(NO2)3, NF] is an extremely attractive oxidant component for propellants and explosives. However, the poor thermostability of NF-based derivatives has been an unconquerable barrier for more than 150 years, thus hindering its application. In this study, the first example of a nitrogen-rich hydrogen-bonded organic framework (HOF-NF) is designed and constructed through self-assembly in energetic materials, in which NF anions are trapped in pores of the resulting framework via the dual force of ionic and hydrogen bonds from the strengthened framework. These factors lead to the decomposition temperature of the resulting HOF-NF moiety being 200 °C, which exceeds the challenge of thermal stability over 180 °C for the first time among NF-based compounds. A large number of NF-based compounds with high stabilities and excellent properties can be designed and synthesized on the basis of this work.

First Time

We have applied the 45° reflectometry for the first time to study exciton-polaritons in quantum wells. The 45° reflectometry is a new polarization-modulation technique, which is based on the measurement of the difference [Formula: see text] between the p-polarization reflectivity (Rp) and the squared s-polarization reflectivity [Formula: see text] at an angle of incidence of 45°. We show that [Formula: see text] spectra may provide qualitatively new information on the exciton-polariton modes in a quantum well. These optical spectra turn out to be very sensitive to the zeros of the dielectric function along the quantum-well growth direction and, therefore, allow to identify the resonances associated with the Z exciton-polariton mode. We demonstrate that 45° reflectometry could be a powerful tool for studying Z exciton-polariton modes in near-surface quantum wells, which are difficult to observe in simple spectra of reflectivity Rp

The Russian Language

The aim of the study was to develop linguistic and methodological theoretical aspects of training the skill of paraphrasing, which constitutes an important element of reading literacy. To this end, the authors reviewed research and educational publications in the field of teaching the Russian language and conducted a pedagogical experiment to analyse pedagogical processes. Interrelation between the infosphere and axiosphere of Russian language lessons within the pedagogical discourse involves the division of didactic texts into informational and axiological, including modern linguistic and ethnographic texts that manifest Russian cultural concepts in the new information age. It is shown that various aspects of teaching paraphrasing and interpretation techniques on the basis of informational texts have already been elucidated quite efficiently. However, formation of the axiological component of reading literacy (teaching to paraphrase on the basis of linguo-ethnographic texts) has been undertaken within the framework of the present study for the first time. These issues should be considered comprehensively, in the context of language and values-based development of a personality.

Information on the karyotypes of Turkish species of Cerambycidae is scanty. Our study contributes to the knowledge of the karyological data (chromosomal number and mechanism of sex determination) of five Turkish longicorn beetles; karyotypes of four taxa, one endemic, are described for the first time and for the remaining one, Purpuricenus budensis (Götz, 1783), the previously published chromosome count is confirmed. The chromosome number of Purpuricenus desfontainii inhumeralis Pic, 1891 and Purpuricenus budensis (Götz, 1783) (Cerambycinae, Trachyderini) was found to be 2n = 28 (13 + Xyp); Clytus rhamni Germar, 1817 and Plagionotus floralis (Pallas, 1773) (Cerambycinae, Clytini) 2n = 20 (9 + Xyp); and the endemic Dorcadion triste phrygicum Peks, 1993 (Lamiinae, Dorcadionini) 2n = 24 (11 + Xyp). In view of the paucity of data available until now, our study is important for both to improve the poor karyological knowledge of Turkish Cerambycidae and to provide an incentive for other researchers.

There is a review of floral studies of the water bodies in Minsk Region and National Park “Belovezhskaya Pushcha”. 75 new locations of 20 rare aquatic and riverside plant species coming at the water and 1 hybrid were found. 7 of these species are listed in the Red Book of the Republic of Belarus, 5 species are included into the category of Least Concern and Data Deficient. Potamogeton berchtoldii Fieber, Utricularia minor L., Potamogeton acutifolius Link, P. nodosus Poir., Salvinia natans (L.) All. are reported for the first time from National Park «Belovezhskaya Pushcha». The spreading of Berula erecta (Huds.) Coville on the territory of National Park is considered in detail. New locations of Nuphar pumila (Timm) DC., Ranunculus kauffmannii Clerc., Najas major All., Berula erecta, Glyceria lithuanica (Gorski) Gorski, Conioselinum tatari­ cum Hoffm. in Minsk Region, which were not included in 4th edition of the Red Book, have been described. A brief description of habitat environmental conditions is given for the revealed species of aquatic plants, and their phytocoenotic confinement is also pointed out. New information on the locations of protected aquatic plant species should be used to monitor their populations and prepare the documents of protection.
