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.

AbstractEnteric infections caused by the gram-negative bacteria enterotoxigenic Escherichia coli (ETEC), Vibrio cholerae, Shigella flexneri, and Salmonella enterica are among the most common and affect billions of people each year. These bacteria control expression of virulence factors using a network of transcriptional regulators, some of which are modulated by small molecules as has been shown for ToxT, an AraC family member from V. cholerae. In ETEC the expression of many types of adhesive pili is dependent upon the AraC family member Rns. We present here the 3 Å crystal structure of Rns and show it closely resembles ToxT. Rns crystallized as a dimer via an interface similar to that observed in other dimeric AraC’s. Furthermore, the structure of Rns revealed the presence of a ligand, decanoic acid, that inhibits its activity in a manner similar to the fatty acid mediated inhibition observed for ToxT and the S. enterica homologue HilD. Together, these results support our hypothesis that fatty acids regulate virulence controlling AraC family members in a common manner across a number of enteric pathogens. Furthermore, for the first time this work identifies a small molecule capable of inhibiting the ETEC Rns regulon, providing a basis for development of therapeutics against this deadly human pathogen.

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.

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.

Bulgarian carabid fauna is relatively well studied but there are still many species and regions in the country lacking enough research. The present paper aims at complementing the data about the distribution of the carabids from the subfamily Trechinae, containing many diverse, interesting and endemic species. Currently, 55 species of Trechini, 118 species of Bembidiini (incl. Tachyina), and 13 species of Pogonini are known in Bulgaria. This study gives new information and new records on 41 Trechinae species and 17 zoogeographical regions and subregions. The material was collected in the period from 1979 to 2020 through different sampling methods. There are 20 species recorded for the first time in different regions. Two species are reported for the second time in the regions where they were currently collected. Seventeen species haven’t been reported for more than 20 years from the Boboshevo-Simitli valley, Sandanski-Petrich valley, Rila Mts., Pirin Mts., and Slavyanka Mts., and are now discovered there again.

This introduction to the edited volume by Brown and Bey summarizes past research on the Preclassic Maya and discusses an explosion of new information from the last fifteen years pushing back the origins of social complexity into the Middle Preclassic. This chapter highlights the fact that this volume brings together important archaeology and research considering the Middle and Late Preclassic periods from both the southern and northern Maya lowlands for the first time. The Late Preclassic was long thought to be the time period by which archaeologists could explain the rise and nature of Classic Maya culture. However, as the fifteen chapters in this volume argue, any discussion of the development of social complexity must be focused on the Middle Preclassic (1000-300 B.C.).

Nickel-Titanium, commonly referred to as Nitinol, is a shape-memory alloy with numerous applications due to its superelastic nature and its ability to revert to a previously defined shape when deformed and then heated past a set transformation temperature. While the crystallography and the overall phenomenology are reasonably well understood, much remains unknown about the deformation and failure mechanisms of these materials. These latter issues are becoming critically important as Nitinol is being increasingly used in medical devices and space applications. The talk will describe the investigation of the deformation and failure of Nitinol using an in-situ optical technique called Digital Image Correlation (DIC). With this technique, full-field quantitative maps of strain localization are obtained for the first time in thin sheets of Nitinol under tension. These experiments provide new information connecting previous observations on the micro- and macro-scale. They show that martensitic transformation initiates before the formation of localized bands, and that the strain inside the bands does not saturate when the bands nucleate. The effect of rolling texture, the validity of the widely used resolved stress transformation criterion, and the role of geometric defects are examined.

Purpose The purpose of the paper is to give a brief description of the new topic introduced for the first time at the EASN Conferences. Design/methodology/approach The topic concerns the heliosphere, the nearest surrounding of the Sun and thus the nearest vicinity of the Earth. The heliosphere is created due to the interaction between the solar wind and the local interstellar medium. Findings This paper does not include any new information about the heliosphere and only introduces a new topic to this journal. It is briefly shown how heliospheric structures are formed, what factors affect a shape of the heliosphere, what measurements are made by Ulysses, Voyager and IBEX space missions (important for the heliosphere modeling) and how obtained data are used to validate theoretical results. Practical implications To categorize the paper under one of these classifications, research paper, viewpoint, technical paper, conceptual paper, case study, literature review or general review, the authors chose a paper type, general review, as the closest category to this paper. However, it is not a purpose of this paper to provide an extensive review of the community efforts to investigate the physical processes in the vicinity of the heliosphere interface. This is mostly a status report. Originality/value As the new topic in this journal, the article introduces in detail only a small number of aspects connected with heliosphere models. Interplanetary and interstellar magnetic field structures are primarily described. Other factors are only mentioned.
