Published: April 2023

Abstract
A thorough comparative analysis was conducted between pure epoxy and a novel epoxy composite that included bentonite and WO3 nanoparticles in varying ratios. This study examined five distinct novel epoxy samples (E00, EB0, EBW1, EBW2, and EBW3) to assess their radiation shielding efficiency (RSE), taking into account the addition of bentonite and WO3 nanoparticles. Furthermore, the study compared the RSE of pure epoxy with that of the novel epoxy composite. To evaluate the radiation shielding ability of the studied epoxy samples, a few radiation shielding parameters such as linear attenuation coefficient (LAC), mass attenuation coefficient (MAC), mean free path (MFP), RSE, and transition factor (I/I
0) were calculated. The RSE values of the epoxy samples were E00 (63.41%), EB0 (87.17%), EBW1 (98.26%), EBW2 (99.82%), and EBW3 (99.99%) at an energy of 0.06 MeV with 4 cm thickness. With the increase in the incident energy, the half-value layer and MFP values were increased, whereas the LAC and MAC values decreased. In conclusion, it can be stated that the sample EBW3 is more suitable among the five epoxy samples studied for attenuating the incident photon energy from 0.06 to 1.33 MeV. Noteworthily, the obtained results demonstrate that the addition of WO3 nanoparticles enhances the shielding ability of epoxy when compared to the addition of the same amount of bentonite.

Abstract
With the acceleration of power grid modernization, the scale of power grid is expanding. Running operations are becoming increasingly complex. There is a great demand for the analysis and calculation of the operation status of the power grid, line transformation design, fault analysis and treatment, etc. At the same time, with the construction of modern power grids and the continuous development of the power industry, the security problems of power systems have become increasingly prominent. This paper introduced the background of the power data service platform and then conducted academic research and summary on the research and development and design of power data service platform and multidimensional power data service platform. Then it was summarized with the analysis of international journals of emerging power systems. After establishing the algorithm model, the spark platform algorithm framework various algorithms were proposed to provide a theoretical basis for the R&D (research and development) and design of the multidimensional power data service platform. Then it analyzed the factors related to the R&D and design of power data service platform. At the end of the article, the simulation experiment was carried out, and the experiment was summarized and discussed. The experimental results showed that the average value of the neural network on the three criteria is 78.03 %. Therefore, the stability rate, accuracy rate, and recall rate of such algorithms as neural network are excellent in the research and development and design of power data service platform.
Effect of vacancies on the damping attenuation of Mn–Cu–Al–0∼3Sn alloys at room temperature

Published: April 2023

Abstract
Mn–Cu alloys are metal materials, which can be used to reduce vibration and noise from machines. With their inner damping mechanism, the alloys show an excellent damping capacity. However, previous reports show that the damping capacity of the alloys often attenuates after placing at room temperature (RT) for a long time. In the present study, the as-cast Mn–Cu–Al–0∼3 wt% Sn alloys were held at RT for 18 months. Their crystallization morphology was observed using backscattered electron (BSE) technology. The phase distribution was characterized using electron backscatter diffraction (EBSD). Their phase structure was analyzed by using X-ray diffraction (XRD). Their starting martensite transformation temperature (Ms) and damping capacity were measured by using an inverted torsion pendulum device. It is observed for the first time that the FCT phases mainly form in the dendrites. With vacancies diffusing towards boundaries of phases and twins, the boundaries are pinned and the Ms point declines. Hence, the damping capacity attenuates within 18 months. Moreover, the addition of Sn can weaken the decline trend of Ms point and consequently the IF value of the Sn-contained Mn–Cu alloys attenuates less than that of the none-Sn alloy. This research could help us to understand how to cope with the damping attenuation of the Mn–Cu alloys.
The new

ne: an incipient restandardization process in contemporary Italian
Authors: Miola Emanuele 
Published: April 2023

Abstract
The paper deals with an ongoing change in the clitic paradigm of contemporary Italian, namely the incipient overextension of functions of the clitic ne.
In the standard variety ne can only stand for prepositional phrases consisting of di + [noun phrase] and da + [noun phrase], such as those found in genitival, partitive, and locative constructions or in passive ‘by’-phrases. In contemporary Italian, on the other hand, ne is increasingly appearing as a substitute of a + [noun phrase] when used as the second argument of intransitive bivalent verbs, such as accennare (a) ‘to mention’, appassionarsi
(a) ‘to get passionate (about)’, and sopravvivere (a) ‘to survive’. The latter use has not received much attention in the literature.
This overextension is observed in a number of verbs, drawing on data from four corpora of written and spoken Italian, and is discussed as an incipient change from above, originating in formal registers of Italian and moving downwards into the neo-standard and (albeit rarely) colloquial varieties.
The change seems to have been triggered and favored by the fact that the standard variants for that slot of the paradigm, namely locative vi and ci, are avoided because they are considered too obsolete or low-prestige respectively, and also by the fact that these clitics, when combined with others, especially in pronominal verbs, might be judged agrammatical by some speakers.

Abstract
Zahlreiche Simulationsanwendungen unterstützen heutzutage Produktionsplaner und Supply-Chain-Manager bei der Planung und Verbesserungen von Prozessen. Die Transparenz von Statusänderungen und die Kommunikation kurzfristig aufkommender Ereignisse über die Grenzen des eigenen Unternehmens hinaus, werden von gängigen Simulationsanwendungen nicht abgedeckt und passende Maßnahmen zu spät ergriffen. Im Rahmen des Forschungsprojekts Catena-X wird das Konzept eines Simulationsmanagers „Online Steuerung und Simulation“ (OSim) entwickelt. Dieser ermöglicht die Verknüpfung von Simulationsergebnissen auf überbetrieblicher Supply-Chain-Ebene, um ein ganzheitliches Bild über die Einflüsse von verschiedenen Störungsszenarien auf die eigene Produktion zu bieten.

Published: April 2023

Abstract
Der Cyberspace ist ein ständig wachsendes und modernisiertes Umfeld, das angesichts der Interkonnektivität Chancen für die digitale Transformation bietet. Aus der Integration der physischen Umgebung mit der virtuellen Welt entstehen jedoch auch Herausforderungen, die im Ökosystem der Industrie 4.0 gelöst werden müssen. So führen Konnektivität, Virtualisierung und Digitalisierung sowie Charakteristika des Engineerings (E4.0) zu Herausforderungen in Bezug auf die Cybersicherheit in einem Ökosystem, das Cyber-physische Systeme (CPS) und Digitale Zwillinge (DZ) integriert. Die Verwendung digitaler Geräte durch Konnektivität im Product Lifecycle Management (PLM) kann die Angriffsfläche für Cyber-Attacken erhöhen. Daher soll in diesem Beitrag ein Ansatz für die wichtigsten Cybersicherheitsrisiken vorgestellt werden, die durch die Integration von I4.0-Technologien in Produktionsumgebungen entstehen können. Zudem wird ein spezifischer Fahrplan für die PLM-Cybersicherheit vorgestellt und Beiträge zur Cybersicherheit im DZ erörtert.

Published: April 2023

Abstract
Disruptive Ereignisse und bahnbrechende Innovationen können Unternehmen im Kern gefährden. Flexibilität und Wandlungsfähigkeit sind in diesen Fällen nicht ausreichend, um adäquat auf extreme äußere Veränderungen reagieren zu können. Unternehmen müssen sich in diesen Fällen über vorgedachte Korridore hinaus verändern und sich somit agil verhalten. Dieser Beitrag macht einen Vorschlag für eine strukturierte Definition des Agilitätsbegriffs aus Sicht der Fabrikplanung. Hierzu werden aus aus Anforderungen der Wertschöpfung jene vier Agilitätsbefähiger abgeleitet, die die Gestaltung agiler Produktionsnetzwerke ermöglichen. Dabei zeigt sich die Konzeptionierung von Standortrollen als geeigneter Lösungsansatz zur Entwicklung resilienter Produktionsnetzwerke.

Abstract
Um sich in einem schnelllebigen und globalen Markt nachhaltig wettbewerbsfähig aufzustellen, bedarf es innovativer Ansätze, Produkte sichtbar zu machen. Vorreiter wie Apple oder Microsoft stehen mit ihren Marketingstrategien und der Präsentation ihrer Produkte für eine neue Denkweise. Doch wie kann ein klein- oder mittelständiges Unternehmen (KMU) mit solchen Strategien konkurrieren und sich und die eigenen Produkte am Markt erfolgreich platzieren? Der vorliegende Beitrag zeigt auf, wie ein Markteinführungskonzept mithilfe des Design-Thinking-Ansatzes auf Basis der Kundenbedürfnisse modular und skalierbar ausgestaltet werden kann, um auf die jeweiligen Anforderungen des einzuführenden Produktes adaptierbar zu sein.

Published: April 2023

Abstract
KI-Anwendungen versprechen produzierenden Unternehmen zahlreiche Möglichkeiten zur Effektivitäts- und Effizienzsteigerung. Studien zeigen, dass bislang nur eine Minderheit KI-basierte Assistenzsysteme im eigenen Betrieb einsetzt. Ein Grund liegt darin, dass es den Unternehmen schwerfällt, Potenziale strukturiert zu ermitteln und Risiken realistisch abzuschätzen. Der Beitrag präsentiert einen niederschwelligen und partizipativen Ansatz, mit dem ein potenzieller KI-Anwendungsfall identifiziert, spezifiziert und gemeinsam mit betroffenen Stakeholdern hinsichtlich seiner Nutzenpotenziale bewertet werden kann. Das Vorgehensmodell wurde im Rahmen eines Forschungsprojekts entwickelt und in Zusammenarbeit mit produzierenden Anwendungsunternehmen unterschiedlicher Größe pilothaft umgesetzt.
Paraventricular thalamus dynamically modulates aversive memory via tuning prefrontal inhibitory circuitry

Published: April 2023

The impact of stress on the formation and expression of memory is well-studied, especially on the contributions of stress hormones. But how stress affects brain circuitry dynamically to modulate memory is far less understood. Here, we used male C57BL6/J mice in an auditory fear conditioning as a model system to examine this question and focused on the impact of stress on dorsomedial prefrontal cortex (dmPFC) neurons which play an important role in probabilistic fear memory. We found that paraventricular thalamus (PVT) neurons are robustly activated by acute restraining stress. Elevated PVT activity during probabilistic fear memory expression increases spiking in the dmPFC somatostatin neurons which in turn suppresses spiking of dmPFC parvalbumin (PV) neurons, and reverts the usual low fear responses associated with probabilistic fear memory to high fear. This dynamic and reversible modulation allows the original memory to be preserved and modulated during memory expression. In contrast, elevated PVT activity during fear conditioning impairs synaptic modifications in the dmPFC PV-neurons and abolishes the formation of probabilistic fear memory. Thus, PVT functions as a stress sensor to modulate the formation and expression of aversive memory by tuning inhibitory functions in the prefrontal circuitry.Significance Statement:The impact of stress on cognitive functions, such as memory and executive functions, are well-documented especially on the impact by stress hormone. However, the contributions of brain circuitry are far less understood. Here we show that a circuitry-based mechanism can dynamically modulate memory formation and expression, namely, higher stress-induced activity in paraventricular thalamus impairs the formation and expression of probabilistic fear memory by elevating the activity of somatostatin-neurons to suppress spiking in dorsomedial prefrontal parvalbumin neurons. This stress impact on memory via dynamic tuning of prefrontal inhibition preserves the formed memory but enables a dynamic expression of memory. These findings have implications for better stress coping strategies as well as treatment options including better drug targets/mechanisms.

The book analytically compares the postconflict scenario in Colombia after the peace agreement in 2016 with the postconflict experiences in Rwanda by the end of the last century and the context of international cooperation and intervention in post-conflict Guatemala. In these cases, Transnationalism (focused on UN actions) is explicit in international cooperation for multidimensional and multifunctional reconstruction of these societies.
The Connotation in Medieval Appositional Groups
Authors: Zbróg Piotr 
Published: April 2023

Connotation as a syntactic mechanism of announcing a specific component in a sentence occurs or not in appositional groups. Based on the test for the non-ellipticity (or ellipticity) of the utterance, it can be determined whether the opposition base or the apposition itself is connoted (the sentence is then incomplete) or not (after the ellipse of the component, the sentence is still complete). Old Polish appositional groups of the type James and John, sons of Zebedee; Bolesław, priest and heir; chapter „Ut noxius” were reviewed in this article. They have been recorded from all monuments of the Polish language and constitute a representative collection of constructions of this type at that time. As a result of the analysis, it was found that in some types of expressions, the base was connoted (Mary, rose lights) or apposition (You, Lord). There were also groups with an unconnoted base (Piotr mayor from Koźmin) and an unconnoted apposition (stone, margarita). On this basis, the typology of the analyzed groups was established, distinguishing groups with unconnoted base and apposition, with connoted base and apposition, with unconnoted base and connoted apposition, and with connoted base and unconnoted apposition.
Powrót do tradycji w architekturze wnętrz około 1910 roku na przykładzie twórczości Henryka Uziembły
Authors: Wójcik Agata 
Published: April 2023

Niniejszy tekst jest prezentacją wnętrz świeckich zaprojektowanych przez Henryka Uziembłę w dwóch pierwszych dekadach XX wieku. Takie projekty, jak salon muzyczny w sanatorium Dłuskich w Kościelisku, wnętrza kinoteatru Uciecha w Krakowie, teatru Bagatela w Krakowie, hotelu Krakowskiego we Lwowie i inne, zostały wpisane w nurt w projektowaniu wnętrz, który możemy nazwać „spojrzeniem wstecz”. Trend ten widoczny był zwłaszcza w projektowaniu wnętrz we Francji i Austrii. Cechował się łączeniem różnych inspiracji, m.in. stylu Ludwika XVI, klasycyzmu, empiru, orientu, sztuki ludowej. Pozwalał na swobodę twórczą, eksperymentowanie z kolorami, formami, stylami. Charakteryzowały go intensywne i kontrastowo użyte kolory zastosowane zarówno w dekoracji ścian, mebli, jak i ich tapicerki. Nurt ten umożliwiał nadawanie miejscu atmosfery podkreślającej jego funkcję lub odwołującej się do przeszłości tego miejsca.
Od szafy wielofunkcyjnej do Cepelii – powojenne projekty mebli Władysława Sowickiego z lat 1945–1954
Authors: Wereszczyńska Agata 
Published: April 2023

Celem artykułu jest omówienie i prezentacja powojennych projektów mebli Władysława Sowickiego, które powstały w latach 1945–1954. Standaryzacja wnętrz mieszkalnych w omawianym okresie zmusiła projektantów do zmiany podejścia do projektowania wyposażenia powierzchni normatywnych. Zaczęto odchodzić od mebli gabarytowych na rzecz mebli mniejszych, węższych, często wielofunkcyjnych czy segmentowych, które pasowałyby do skali nowych, małych mieszkań. W tym czasie Sowicki podjął współpracę z Biurem Nadzoru Estetyki Produkcji, później z Instytutem Wzornictwa Przemysłowego, oraz z Cepelią. W ramach tej współpracy powstały projekty mebli zgodnych z obowiązującymi wówczas trendami projektowymi – lekkie, ekonomiczne, funkcjonalne, wykorzystujące nowoczesne surowce. Sowicki projektował popularne w tamtym czasie meble wielofunkcyjne, meble gięte, ze sklejki, tapicerowane fotele uszaki – wszystkie o nowoczesnych, „nerkowatych” liniach charakterystycznych dla wzornictwa lat 50. i 60. Odrębną grupę stanowią projekty mebli wykonywane na zlecenie Cepelii, które cechuje zmodernizowana ludowość nawiązująca do „ekskluzywnego rustykalizmu” wnętrz inspirowanych tradycyjnym rzemiosłem.
Przyjęta na potrzeby artykułu metoda badawcza obejmowała kwerendę biblioteczną, analizę materiału archiwalnego pozostającego w posiadaniu rodziny Władysława Sowickiego, a także przegląd literatury naukowej. Wszystkie omawiane w artykule projekty mebli autorstwa Władysława Sowickiego pozostają w posiadaniu rodziny artysty.

El cannabis es la droga ilegal más consumida en España con un consumo que se concentra principalmente en la adolescencia y primeros años de la edad adulta. Los objetivos de este estudio fueron estimar la prevalencia de consumo de cannabis, de trastorno por consumo de cannabis (CUD) y de consumo dependiente (CD) en la población gallega ≥16 años y caracterizar a los consumidores y a los consumidores dependientes. Los datos proceden de dos estudios transversales del Sistema de Información sobre Conductas de Riesgo realizados en 2017 (n = 7.841) y 2018 (n = 7.853). Se utilizó el test de adicción al cannabis (CAST) para identificar a los consumidores con CUD y/o CD. Se estimaron prevalencias y se ajustaron modelos de regresión para identificar variables asociadas al consumo y CD de cannabis. El 2,7% (IC 95%: 2,5-3,0) de la población gallega ≥16 años consumía cannabis en el momento de la encuesta (2017-2018), siendo esta prevalencia del 9% en el grupo de 16-24 años. La prevalencia disminuye con la edad y es superior en hombres en todos los grupos etarios. La prevalencia de CUD en los consumidores fue del 69,5% (IC 95% 61,1-78,1) y de CD del 49,2% (IC 95% 44,6 -53,9). Consumir tabaco es el mayor determinante para ser consumidor de cannabis [OR = 19,8 (IC 95% 13,8-28,4)] y consumir diariamente cannabis para ser consumidor dependiente [OR = 5,5 (IC 95% 3,2-9,5)]. El consumo de cannabis entre la población gallega es bajo, aunque entre los jóvenes de 16-24 años, que son los que muestran más probabilidad de CD, la prevalencia es elevada. Las medidas de prevención deben dirigirse especialmente a la población más joven de 16 años para frenar su consumo y el desarrollo de consecuencias como el CUD y el CD.
Substitution of higher-strength beers with zero-alcohol beers: Interrupted time series analyses of Spanish household purchase data, 2017-2022
Authors: Anderson Peter , Kokole Daša 
Published: April 2023

In its action plan (2022-2030) to reduce the harmful use of alcohol, WHO calls on economic operators to “substitute, whenever possible, higher-alcohol products with no-alcohol and lower-alcohol products in their overall product portfolios, with the goal of decreasing the overall levels of alcohol consumption in populations and consumer groups”. This paper investigates substitution within beer brands at the level of the consumer, based on Spanish household purchase data using interrupted time series analysis. For households (n = 1791, 9.1% of all households) that newly bought at least one of eleven branded zero-alcohol beers (responsible for over three-quarters of all zero-alcohol beer purchased), the associated purchases of all grams of alcohol after the first purchase of zero-alcohol beer were reduced by 5.5%, largely due to substituting every one litre of higher strength beer (ABV > 3.5%) with 0.75 litres of same-branded zero-alcohol beer (ABV = 0.0%). For households (n = 337, 1.8% of all households) that had never previously purchased a same-branded higher-strength beer, but newly purchasing a same-branded zero-alcohol beer, the associated purchases of all grams of alcohol after the first purchase of zero-alcohol beer were reduced by 14%; this reduction was largely due to such households’ decreasing their associated purchases of wines and spirits. Thus, at the level of the consumer, based on Spanish household purchase data of branded zero-alcohol beers, the evidence behind WHO’s call for substitution appears to be substantiated.
