The genus Alchemilla (Rosaceae) in the Republic of Mordovia flora
Authors: Chkalov Andrey V. , Pismarkina Elena V. , Silaeva Tatyana B. 
Published: June 2024

In the flora of the republic, 41 Alchemilla species have been registered. Of the previously noted species, the presence of A. devestiens, A. glaucescens, and A. heptagona in the region is not confirmed by herbarium collections. The species A. atrifolia, previously listed for the republic but included in the most recent synopses only as a synonym of A. lindbergiana, is considered by us as a separate species. Previous works of co-authors have supplemented the Alchemilla list of the Mordovia flora with such species as Alchemilla argutiserrata, A. barbulata, A. cheirochlora, A. homoeophylla, A. kemlensis, A. longipes, A. mininzonii, A. psiloneura, A. pustynensis, A. schmakovii, A. sibirica, A. tichomirovii, A. vorotnikovii, and A. zimoenkensis. Here, two species are recorded for the first time for the republic – A. hians and A. prasina. The presence of A. litwinowii in Mordovia, which was previously noted exclusively on the basis of collections attributed subsequently to the newly described species A. tichomirovii, has also been confirmed. An original key, comprising all species of the genus registered in the middle part of the Volga River basin, has been compiled.
Tracking Bodies Motions on the Lunar Surface: Apollo XVI Footage, a case of study.
Authors: Simon Andrea , Michelotti Alessio 
Published: June 2024

This manuscript introduces a robust analytical method to trace and analyze the movement of bodies shot during the Apollo XVI mission on the lunar surface. By employing both 2D and 3D analysis techniques, we aim to provide a detailed comparison of the observed kinematic events against theoretical models.
The paper extends a previous work focused on the kinematics of lunar dust utilizing footage from the “Grand Prix” sequence of the Apollo XVI mission "Ballistic motion of dust particles in the Lunar Roving Vehicle dust trails" published in 2012 on the American Journal of Physics by Mihaly Horanyi and Hsiang-Wen Hsu:
https://www.researchgate.net/publication/258468670 [
Ann. 1 –
Ann. 2].
The objective is to validate lunar environmental models and enhance the understanding of motion dynamics on the lunar surface. This comprehensive analysis reconstructs the image production chain and the photographic and television transmission technology used during the Apollo 16 mission and indicates the good practices to follow for the correct digital transposition of the various types of film produced.
Not only does it reassess existing data but also introduces new methodologies in order to interpret the lunar surface motions of bodies captured during Apollo missions.

Abstract
In this work we investigate the influence of closed (“C”) or open (“O”) extrusion degassing, and low (5 MPa – “L”) or high (90 MPa – “H”) holding pressure during injection molding on the properties of wood-plastic composite (WPC) based on high-density polyethylene (HDPE) flakes compatibilized with 5 wt% maleic anhydride-modified polyethylene (MAPE), 5 wt% lubricant (Struktol® TPW 113), and 40 wt% cashew nutshell powder (CNSP). Two reference compounds were extruded with closed degassing and injected at 90 MPa of holding pressure: (1) HDPE flakes extruded with 5 wt% MAPE and 5 wt% Struktol® TPW 113 (HDPEad_C-H) and (2) HDPE flakes previously melt mixed in an internal mixer with 5 wt% CNSL (HDPEr/5CNSL) and then extruded with the same additive content (HDPEad/5CNSL_C-H). At 90 MPa holding pressure, the extract content of WPC slightly increased and CNSL acted as a lubricant and poor plasticizing agent, reducing the crystallinity and density of the additivated matrix (HDPEad_C-H), increasing the flow rate without significantly changing the tensile strength. On the other hand, low holding pressure (5 MPa) favored the volatilization and expansion of the residual CNSL in the WPC, which acted as a blowing agent improving filling of the mold cavity and avoiding sink marks. Sample extruded with open degassing (atmospheric pressure) did not significantly change the extract content, but favored CNSL diffusion from particles to matrix, which subsequently during injection molding led to its entrapment at the interface, resulting in low adhesion, especially at high holding pressure that hinders CNSL expansion and vaporization. These findings contribute to understand the role of residual CNSL of CNSP in WPC properties and thus, to strengthen the plastics recycling chain and reduce carbon footprint.
Depth of intact vascular plexus – visualized with optical coherence tomography – correlates to burn depth in thoracic thermic injuries in children

Published: June 2024

Abstract

Objectives
Deep thermal injuries are among the most serious injuries in childhood, often resulting in scarring and functional impairment. However, accurate assessment of burn depth by clinical judgment is challenging. Optical coherence tomography (OCT) provides structural images of the skin and can detect blood flow within the papillary plexus. In this study, we determined the depth of the capillary network in healthy and thermally injured skin and compared it with clinical assessment.

Methods
In 25 children between 7 months and 15 years of age (mean age 3.5 years (SD±4.14)) with thermal injuries of the ventral thoracic wall, we determined the depth of the capillary network using OCT. Measurements were performed on healthy skin and at the center of the thermal injury (16 grade IIa, 9 grade IIb). Comparisons were made between healthy skin and thermal injury.

Results
The capillary network of the papillary plexus in healthy skin was detected at 0.33 mm (SD±0.06) from the surface. In grade IIb injuries, the depth of the capillary network was 0.36 mm (SD±0.06) and in grade IIa injuries 0.23 mm (SD±0.04) (Mann–Whitney U test: p<0.001). The overall prediction accuracy is 84 %.

Conclusions
OCT can reliably detect and differentiate the depth of the capillary network in both healthy and burned skin. In clinical IIa wounds, the capillary network appears more superficial due to the loss of the epidermis, but it is still present in the upper layer, indicating a good prognosis for spontaneous healing. In clinical grade IIb wounds, the papillary plexus was visualized deeper, which is a sign of impaired blood flow.
Biased interrogatives in Camuno
Authors: Fiorini Matteo 
Published: June 2024

Abstract
This article discusses the properties of interrogative structures biased in the set of their possible answers by the particle po in Camuno. In declarative structures, po signals that according to the speaker, a proposition p is surprisingly controversial in the utterance world w. In interrogative structures, the same particle identifies the only subset of

〚

p
〛

f

[\kern-2pt[ {p]\kern-2pt] }^{f}

, the set of focus alternatives to p, that can satisfy the existential presupposition introduced by the question. However, po additionally signals that such a subset is non-factual, i.e., controversial, in w. A characterization of po as an element operating on sets of alternatives offers an important tool to investigate the numerous pragmatic readings conveyed by po and account for the restrictions in its distribution. The semantic properties of the po-interrogatives can, in fact, capture the mirative and counterfactual readings also attested in cognate forms in neighboring varieties. Thus, this analysis represents an important step in exploring a possible unified account.
Come lavorava Lucano? Su possibili varianti d’autore nel Bellum civile
Authors: Russotti Ambra 
Published: June 2024

Abstract
That authorial variants survive in the transmission of the works of Lucan is a hypothesis legitimated by some objective data, yet the problem has been given very little attention in research since the important discussion by Fraenkel (1926). The present paper offers an analysis of the question that starts from the cases already identified and discussed by Fraenkel, adding some examples newly identified here. In particular, the goal is not to discuss single cases evaluated separately, but rather to examine the distribution of suspected variants in coherent macro-systems, the shared ratio of which could offer a plausible way of establishing an authorial intervention. In their turn, the systems of variants proposed and discussed here allow us to advance hypotheses about Lucan’s compositional method.
Conflicting modalities in feature film: from contrapuntal editing to internal diegetic sound
Authors: Oja Martin 
Published: June 2024

Abstract
This article approaches sensory modalities as semiotically active factors and organizing principles in meaning-making. The focus will be on the special case where modalities mismatch in film – i.e., the soundtrack and visuals present contradictory meanings. The conflict can be characterized by the concept of synthesis that emerges in theories of Eisenstein, Barthes, Jakobson, Lotman, and cognitivists. The artistic functions of such synthesis will be discussed with the help of examples from selected feature films. In the first place, conflicting modalities are inspected in the light of Juri Lotmanʼs theory of two incompatible, but still complementary languages that make up a mechanism for generating new information. In addition, the prospects of evaluating modality conflicts will be touched upon, dismissing synchrony and redundancy as the scale parameters, but acknowledging Lotmanʼs model of space as a primary modeling system that is capable of representing semantic conflicts.
Combining formal and functional approaches to variation in (morpho)syntax: Introduction to the special issue
Authors: Strobel Thomas 
Published: June 2024

AbstractThis special issue examines the question of how both formal(ist) and functional(ist) accounts or elements of theorizing can contribute to the explanation of (morpho)syntactic variation. Are formal and functional approaches really irreconcilable with each other, as often seems to be taken for granted by their respective advocates? It will be argued instead that they are rather complementary and that both can make a valuable contribution to explaining linguistic variation, in synchronic as well as diachronic respects. The integration of ways of looking at a certain phenomenon or problem from the respective other camp is proven to provide a significant added value and should not be excluded. The volume focuses on several Germanic languages and dialects, more specifically on German, Dutch, and Swedish varieties. It unites different formal and functional perspectives and, not least, it considers also semantic and phonological factors. The models covered include different versions of generative grammar, information-based morphology, construction grammar/construction morphology, natural morphology, and sociolinguistics.
On the asymmetry of wh-doubling in varieties of German and Dutch

Published: June 2024

Abstract
This paper combines experimental, theoretical and quantitative approaches to syntactic microvariation. The empirical goal is to clarify the situation with respect to wh-doubling (also: wh-copying) in varieties of German and Dutch. With a large-scale survey in the German and Dutch language areas we sought to establish which speakers allow wh-doubling, which speakers allow right-complexity, i.e., configurations in which the lower copy of the wh-dependency is more complex that the higher one, and which speakers allow left-complexity, i.e., the reverse, with a more complex higher copy. We also wanted to know whether there are associations between these properties, to identify groups of speakers and dialects. We found three types of grammars: (i) a grammar that allows both wh-doubling and right- and left-complexity, (ii) a grammar that allows wh-doubling and has a strong preference for right-complexity over left-complexity, and (iii) a grammar that does not allow any wh-doubling configuration. This shows that there is a clear limit to variation in this domain. Grammars with a preference for left-complexity do not exist. We then point out the consequences of these findings for the copy theory of movement, and for analyses that enrich this theory with the option of partial deletion.
Exploring structural and optical properties of shock wave-loaded polycrystalline picric acid: implications for molecular engineering applications
Authors: Vijayan Muthuvel , Aswathppa Sivakumar , Kumar Raju Suresh , Haribabu Arul , Sathiyadhas Amalapushpam Martin Britto Dhas 
Published: June 2024

Abstract
The shock wave impact on hydrogen-bonded organic materials’ structural properties and their responses with respect to their associated functional properties is one of the most prevalent research topics because of the possible emergence of unusual functional properties. Presently, we intend to examine the structural response of the poly-crystalline picric acid samples under shocked conditions. The crystallographic structural responses and the linear optical properties of the test samples have been examined by powder XRD analysis, ultra-violet diffused reflectance spectroscopy (UV-DRS) and Raman spectroscopy, respectively. Under shocked conditions, a considerable modification in the diffraction peak positions and their intensity changes could be witnessed. Notably, linear optical transmittance profiles show remarkable changes according to the number of applied shock pulses, such that the 150-shocked sample has the highest optical transmittance of 53.9 % at 350 nm, whereas the control sample has an optical transmittance of 6.6 %. The Raman spectrum shows the vibrational groups of material that are stable in shocked conditions with similar intensity changes. Based on the obtained XRD, UV-DRS and Raman results, shock wave-induced picric acid samples have remarkably improved characteristics of optical transmittance, which is highly favorable for non-linear optical applications.
Ukrainian book influencers of thematic telegram channels from the perspective of influencer marketing
Authors: Simashova Anastasiia 
Published: June 2024

The article examines the peculiarities of the functioning of author's book blogs in the Ukrainian segment of Telegram. The author argues that writing reviews by readers on a social network has long been a much larger phenomenon than reader promotion of books, but is an expression of the global phenomenon of online influencer marketing. It is proposed to adopt the term "book influencer" as a generally accepted international term for book influencers. The study analyses Ukrainian author's book blogs on Telegram and identifies 17 most popular ones by the number of subscribers. The article focuses on the peculiarities of bloggers' public identity, in particular, in the selection of content and the use of labelling for posts. It is proved that the main characteristic of the public identity of book influencers is reading as a lifestyle. Some of the latest strategies for engaging the audience are described, in particular, the activation of subscribers using the military-patriotic theme.
It is found that book bloggers do not act on the basis of anonymity, but are interested in developing their own brand and creating social capital. posting posts on a commercial basis, and cooperation with publishers is not always on a barter basis. It has been found that most of the blogs we analysed have labelled advertising (11 out of 17), however, only a few bloggers openly state the terms of advertising.
It is noted that in addition to the marketing function, book telegram channels have a value-oriented function for their audience. It is determined that book influencers are now defending the Ukrainian book and Ukrainian book publishing, and condemning Russian literature as part of the identity of the aggressor country in the Russian-Ukrainian war.

Published: June 2024

AbstractPurposeThe present study compares the efficacy of refractive surgery using third-generation and sixth-generation laser vision correction procedures in terms of postoperative visual acuity. The goal of the authors was to determine whether advances in laser technology had improved patients' uncorrected visual acuity, as measured at six-month follow-ups.Materials/MethodsResults were reported from one of Europe's leading laser eye clinics, which has performed an outstandingly high number of treatments (over 100,000). The results of the clinic's first 10,000 treatments and most recent 10,000 treatments were evaluated.ResultsThe analysis was performed by treated dioptric range and age group. The raw six-month visual acuity results show a statistically significant improvement over the last 10,000 interventions. The treatments resulted in significant improvements in all groups compared to the previous technology. With the new devices, visual acuity increased to above 1.0 in young myopes. The best results were seen in patients between 18 and 45 years of age, in the dioptric range between −1.0 D and −6.0 D.ConclusionsIt can be concluded that advances in technology improved refractive outcomes in all patient groups. This conclusion has excellent reliability and predictability due to the particularly high number of cases.

Published: June 2024

Transverse length related malocclusions are common in orthodontic clinics. They can be as simple as posterior crossbite or as severe as Class III malocclusion, where the jaw is asymmetrical. Cases of lateral malocclusion range from simple alveolar problems to complex problems such as bone asymmetries that occur after adolescence and lead to temporomandibular joint disorder (TMD). This is a review article to discuss types of transverse malocclusions and most latest innovations in diagnosis and treatment planning. Many methods of diagnosis and correcting maxillary transverse discrepancies have been discussed. Orthodontists should know about the drawbacks of each method.
