Optimizing the Solution Annealing of Additively Manufactured AlSi10Mg
Authors: Strauß L. , Lübbecke S. , Löwisch G. 
Published: October 2023

AbstractLaser-based powder bed fusion of metals exhibit process-induced anisotropy and residual stresses, making post-manufacturing heat treatment occasionally beneficial. For AlSi10Mg, a T6 heat treatment (solution annealing, quenching, artificial aging) is recommended. Nevertheless, mechanical strength decreases as (1) the eutectic Si network dissolves, (2) the amount of dissolved Si in the Al grains decreases, and (3) the size of the silicon particles and aluminum crystals increases during solution annealing. This changes the mechanical characteristics directly or by influencing the formation of precipitation during the aging process. The success of solution annealing is affected by the annealing duration and the part’s temperature at the moment of quenching. Short annealing durations dissolve a sufficient amount of Si and Mg in the Al matrix. Therefore, both the annealing temperature’s holding duration and the heating process significantly impact the resulting microstructure. In this study, samples of different shape and size where subjected to a T6 heat treatment with different solution annealing temperatures and durations. The influence on mechanical properties after quenching and aging was investigated by hardness and tensile tests. Maximum strength is achieved by quenching promptly upon reaching the solution annealing temperature, while longer durations reduce strength as explained by the Larson-Miller parameter.

Abstract
In this article, we used a novel semi-analytical approach, named the optimal auxiliary function method (OAFM), to solve integro-differential equations (IDEs). The OAFM includes an auxiliary function and convergence control parameters, which expedite the convergence of the method. To apply the proposed method, some assumptions regarding small or large parameters in the problem are necessary. We present numerical outcomes acquired via the OAFM alongside those obtained from other numerical techniques in tables. Furthermore, we demonstrate the efficacy and ease of implementing the proposed method for various IDEs using 2D graphs.
An experimental investigation of the interaction of narrators’ and protagonists’ perspectival prominence in narrative texts

Published: October 2023

AbstractIn this paper, we present the results of an experiment investigating the effect of different narrative situations on the availability of locally prominent protagonists as anchor for Free Indirect Discourse (FID). We created items in three conditions: condition A featured a neutral third-person narrator, condition B a homodiegetic first-person narrator and condition C a prominent, evaluative third-person narrator. Participants read several short text segments all ending with FID and were asked to rate the acceptability of the FID sentence. The results revealed that condition B received significantly lower ratings than the other two conditions, whereas there was no significant difference between conditions A and C. An additional study, in which participants had to choose if the thought expressed by FID belonged to the narrator or the protagonist, showed that there was a strong tendency to choose the protagonist as perspectival center in all three conditions. The results from Exp. 1 prove that while the presence of a homodiegetic first-person narrator strongly constrains a locally prominent protagonist’s availability as anchor for FID, it is not similarly affected by the presence of a globally prominent third-person narrator. This further confirms that narrative texts possess an inherent potential for multiperspectivity.

Context. Due to the need for practical implementation of the theoretical provisions of the proposed method of the wireless transmission of the commands for controlling a moving object in conditions of intentional interference.
Objective of the work is a practical verification of the possibility of using a phase-pulse modulation of the linear-frequencymodulated signal for transmission a control commands through physical modeling using microcontrollers.
Method. Analytical calculations of the change in time of the voltage at the input and output of the device for optimal processing of the linear frequency-modulated signal were carried out exclusively using the computing capabilities of the microcontroller. The graphs of changes in time of the relevant parameters were built with the help of Excel using the data output to the monitor of the serial port of the Arduino IDE software environment. A digital oscilloscope with a USB host was used to monitor the operation of a wireless modem to transmit control commands to a moving object.
Results. Analytical calculations and physical modeling using a modern microcontroller proved the operability of the lowfrequency part the wireless remote control modem with using phase-pulse modulation of the linear frequency-modulated signal.
Conclusions. The possibility of using phase-pulse modulation of the linear-frequency modulated signal for the transmission of control commands is considered. This method of transmitting the information component, unlike the existing methods, does not require changing the parameters of the linear frequency modulated signal. The use in the receiver of optimal processing of a linearfrequency-modulated signal of sufficiently big base will allow of the wireless transmission of the commands for controlling a moving object in conditions of the intentional interference. The use of modern microcontrollers made it possible to conduct a practical test of the functionality of the low-frequency part the wireless remote control modem with phase-pulse modulation of the linear-frequency modulated signal through physical modeling.
STUDY OF THE LIV VERTEBRAL BODY LOAD DURING DYNAMIC SIMULATION OF MOVEMENTS IN THE LUMBAR SPINE USING MUSCULOSKELETAL MODELS AFTER POSTERIOR BISEGMENTAL SPINE FUSION PERFORMANCE
Authors: Barkov Oleksandr , Malyk Roman , Karpinska Olena 
Published: October 2023

One of the risk factors for complications in the spinal motion segments of the thoracic and lumbar regions, as well as in the adjacent segments with spinal fusion ones, is changes in the sagittal vertebral-pelvic balance. Purpose. To determine the effect of muscle changes that occur during the performance of two-segment LIV–SI spinal fusion on the load of adjacent motion segments. Material and methods. The spinal fusion of two spinal motion segments of the lumbar spine was simulated at the LIV–LV and LV–SI levels at different angles of segment fixation in the OpenSim programme. Five models were analysed: 1 (basic) — without changes; 2 — changes in the points of attachment and muscle strength; 3 — normo-lordotic fixation; 4 — hypolordotic; 5 —hyperlordotic. The load on the zone of interest was measured as the magnitude of the projection of the force vector depending on the angle of inclination of the torso as a percentage of the body weight. Results. Simulation of the above configurations of the instrumental spinal fusion (intact, normo-lordotic, hyperlordotic, hypolordotic positions due to a change in the angle of the LIV–SI spinal fusion) showed that the load force of the adjacent segments when bent forward depended on the angle of the instrumental spinal fusion performed. Conclusions. As a result of study of the kinematic model of the lumbar spine using bisegmental spinal fusion of LIV–SI, it was proved that the load force of the adjacent segments when bent forward depended on the angle of the instrumental spinal fusion performed. It was determined that the upper adjacent vertebra of the fixation zone had a relatively insignificant increase in load in the case of fixation in the hyperlordotic position; in the hypolordotic position, the load on the upper segment led to an increase in loads on the upper adjacent segment, and in the hypolordic position, it led to a slight decrease compared to the normo-lordotic fixation. According to the results of the study, minimal muscle damage is expected during the surgical intervention, so the reliability of the model is closer to minimally invasive surgery. The developed kinematic models can be useful in the planning of the transpedicular fixation surgery to prevent complications.
Unilateral continuous subclinical paroxysmal activity: an unusual finding in a patient with recurrent absence status
Authors: Velizarova Reana , Genton Pierre 
Published: October 2023

ABSTRACTWe report a patient with a history of rare generalised tonic‐clonic seizures and recurrent absence status who was diagnosed with a rare variant of idiopathic generalised epilepsy and absence status epilepsy. No other pathology was identified and MRI was normal. During a follow‐up of 17 years, we recorded a single unilateral continuous, strictly subclinical, paroxysmal activity which lasted for at least several hours. No control was observed under treatment with phenobarbital, lamotrigine and topiramate. Absence status was aggravated with carbamazepine and generalised tonic‐clonic seizures were not controlled with ethosuximide. Total seizure control was only possible with sodium valproate, which caused weight gain, and the patient has remained seizure‐free for the past 10 years under 1,000 mg/d valproate and 200 mg/d topiramate. The recorded unilateral, long‐lasting, subclinical spike‐and‐wave discharge is quite unusual for idiopathic generalised epilepsy and, in our opinion, occupies a transitional position between generalised and focal activity.

Published: October 2023

Abstract
Repeating large earthquakes (M ≥ 7), waveforms for which are nearly identical, have been identified only on the Mexican subduction thrust near Acapulco. These earthquakes occurred on 1962 (Ms 7.0) and 2021 (Ms 7.0, Mw 7.0). Here, we report on two more sequences of three repeating large earthquakes each in eastern and western Oaxaca, Mexico. The repeating earthquakes in eastern Oaxaca occurred on 23 March 1928 (Ms 7.5), 1965 (Ms 7.6, Mw 7.5), and 2020 (Ms 7.4, Mw 7.4), and in western Oaxaca on 4 August 1928 (Ms 7.4), 1968 (Ms 7.2, Mw 7.3), and 2018 (Ms 7.2, Mw 7.2). Galitzin seismograms of the earthquakes in each sequence at DeBilt, The Netherlands or at Strasbourg, France are strikingly similar for at least 2600 s after the P-wave arrival. Similarity of waveforms of earthquakes in each sequence and tests with seismograms of events locations for which are accurately known suggest that their source areas were less than 10–20 km of each other. Moment-rate functions of these events are remarkably simple. We also document quasi-repeating earthquakes in central Oaxaca on 17 June 1928 (Ms 7.6) and 29 November 1978 (Ms 7.6, Mw 7.6). Such events have similar locations with large overlap in primary slip but are not identical. Recently, Michoacán–Colima earthquakes of 1973 (Ms 7.5, Mw 7.6) and 2022 (Ms 7.6, Mw 7.6) were reported as quasi-repeaters. Repeating or quasi-repeating large earthquakes imply that they are known for all the other events in the sequence if we know the location and gross source parameters of one of them. This permits the estimation of recurrence periods and the delineation of seismic gaps with greater confidence. Repeating and quasi-repeating large earthquakes in Oaxaca, an unique observation, shed new light on seismic hazard of the region, provide further support for the characteristic earthquake model, and reveal remarkably persistent behavior of ruptures through multiple earthquake cycles.

In deze bijdrage en in mijn huidige onderzoek focus ik op de verstaanbaarheid van het Nederlands zoals gesproken door Tsjechische sprekers. Doel is om na te gaan in hoeverre moedertaalsprekers dit “Tsjechisch Nederlands” van A2-, B2- en C1-sprekers verstaan.
Het ERK en de beoordelingscriteria van het CNaVT stellen bepaalde eisen aan het niveau van het Nederlands en kunnen gedeeltelijk als uitgangspunt worden toegepast voor de beoordeling van de uitspraakverwerving. In deze bijdrage neem ik de verstaanbaarheid van het “Tsjechisch Nederlands” van A2-sprekers onder de loep. k maak gebruik van een opname van 53 seconden waarin een A2-spreker een tekst voorleest. De opname liet ik door moedertaalsprekers, docenten NT2 en NVT beoordelen op verstaanbaarheid. Ik wilde nagaan hoe deze opname van een doorsnee spreker van het niveau A2 globaal verstaanbaar is. Ik richtte me tevens op de beoordeling van enkele specifieke aspecten, namelijk: de realisatie van de klemtoon, de intonatie, sjwa en enkele afzonderlijke klanken die uit eerder contrastief onderzoek als knelpunten voor Tsjechische moedertaalsprekers naar voren kwamen. Aan de hand van de beoordeling door de moedertaalsprekers inventariseerde ik vervolgens met dit onderzoek de probleempunten in de uitspraak van A2-sprekers.

Authors: Matuzkova O. P. , Kovalenko O. V. 
Published: October 2023

The article focuses on dynamic language-culture correlation in the context of modern linguoculturology. This linguocultural research is a version of cultural studies which places language at its heart. At an everyday, human and scientific level linguocultural interests, pursuits and problems have never been more important. The subject matter of this article is therefore crucially topical and reflects the current demand of modern linguistics for new and profound research in this sphere. The topicality is also determined by the linguoculturology evolution into integrative interdisciplinary field of modern humanitarian knowledge in which perspectives from different disciplines can be selectively drawn on to examine the relations of culture, mind and language. The research focuses on dynamic, synergetic mutual interaction of language, culture and mentality reflected in the academic concept and viewed in theoretical aspect. It also defines linguoculture as a key concept of XXI century linguoculturology. Our study relies substantially on the application of linguistic descriptive methodology and devices. The main aim of the work is to describe the complex mechanism of two fundamental categories synergy. The objective determined the tasks of the research: to clarify and describe continuous dynamic complex process of language and culture correlation through linguoculturilogy perspective and define the much disputed key terms –“linguoculturology”,’linguoculture” and “the language of culture”. The research claims that language and culture realationship is characterized by two-sided parity, mutual influence and dependence, inseparable integrity and coherence.
THE FORMATION OF ORTHOGRAPHIC NORM IN GERMAN LANGUAGE

Published: October 2023

The article is about the formation of orthographic norm in German language since the XVII century up to the present time. The stages of the formation of German orthographic norm are examined with the description of the main characteristics of each of them. On the basis of the research works of prominent Ukrainian and foreign linguists and conference documents related to the formation and codification of a definite orthographic norm in German (Standarddeutsch) from the XVII century up to the present day, a certain simplification of certain spelling rules in modern German and more consistent adherence to the etymological principle of spelling have been revealed. The aim of this paper is to describe the processes of orthographic norm formation in the German language. The object of the research is orthographic peculiarities of the German written language in XVII–XIX centuries. The subject of the research is orthographic changes in the German language in the XVII–XIX centuries. The research is based on the works of prominent Ukrainian and foreign linguists and conference documents related to the formation and codification of a universally accepted orthographic norm in the German language. The conducted research has revealed the ways in which the orthographic norm in the German language has developed. Undoubtedly, all the authors of the various orthographic reforms were motivated to improve German spelling in order to meet the cultural objectives of the German language at every stage of its development. However, only time will show how much the new rules will ease the task of using the German language in writing. In our opinion, the authors of the latest reform avoided radical reforms, which explains, for example, the preservation of capitalization of nouns in German. The results of the study can be useful in lectures on the History of the German Language, Historical Phonetics of the German Language, as well as in teaching and learning a practical course of German.
