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.

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 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.

A population of Xiphinema bolandium from the Baviaanskloof Wilderness Area in the Eastern Cape Province was studied, and the four juvenile stages described and figured for the first time. New distribution records are listed from several localities in the Western Cape Province, mostly from vineyards and peach orchards, as well as from fynbos.

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.

Background and Aims: Inhabitants of the Purépecha Plateau preserve an excellent ancestral knowledge on medicinal plants used for dermatological affections, which has not been documented. An ethnopharmacological survey was carried out in this region to gather information on the use of medicinal plants and herbal preparations for treating dermatological affections, to disseminate the Purépecha indigenous knowledge and identifying promising plants for developing new formulations for cutaneous conditions.Methods: The study was conducted in the 21 municipalities that compose the Purépecha Plateau. A total of 86 local inhabitants (62 women and 24 men) were interviewed. The data were quantitatively analyzed through the determination of the use value, fidelity level and informant consensus factor.Key results: A total of 97 plant species belonging to 47 families were documented for treating 19 dermatological conditions on the Purépecha Plateau. Asteraceae was the leading family among the collected medicinal plants (20.61%), followed by Lamiaceae (13.40%) and Solanaceae (5.15%). The largest number of plants was used for the treatment of cuts (40.20%), skin inflammation (37.11%) and rash (37.11%). The aerial parts were the most commonly used (34.75%). The medicinal plant species with larger use values were Heterotheca inuloides (0.53), Aloe vera (0.37) and Oenothera rosea (0.21). The comparison of results with ethnomedicinal literature worldwide revealed that 8.25% of plants used on the Purépecha Plateau were recorded for the first time for the treatment of dermatological affections.Conclusions: This study provides new information on medicinal plants used on the Purépecha Plateau to treat cutaneous diseases. Future pharmacological and toxicological investigations are required to demonstrate the efficacy and safety of these species for treating dermatological affections.
