Thermophysical characterization of mustard husk (MSH) and MSH char synthesized by the microwave pyrolysis of MSH
Authors: Verma Akanksha , Tripathi Manoj 
Published: May 2023

Abstract
Thermophysical properties are calculated to determine performance parameters comprising specific heat capacity, thermal conductivity, thermal diffusivity and they are directly related to the dynamics of the material at atomic level and for thermal treatment of mustard husk (MSH) and MSH char, they play a vital role. Temperature dependence of thermophysical properties of MSH and MSH char have been investigated within the temperature range between 30 and 110 °C. MSH char is synthesized by the microwave pyrolysis of MSH. Thermogravimetric analysis of MSH and MSH char confirmed that MSH is more thermally stable as compared to MSH char. Moreover, it gave information about the degradation behaviour of MSH and MSH char. Thermophysical properties are measured by thermal analyser, based on the transient hot wire technique which is suitable to measure the thermal conductivity at elevated temperatures. At room temperature, thermal conductivity and thermal diffusivity of MSH are 0.187 W m−1 K−1 and 0.132 mm2 s−1, respectively. Specific heat capacity of MSH and MSH char are found to be almost same (1.349 kJ kg−1 K−1 for MSH and 1.310 kJ kg−1 K−1 for MSH char). Thermal conductivity and thermal diffusivity values are decreasing on increasing the temperature while specific heat capacity is increasing linearly on increasing the temperature. Low thermal conductivity and thermal diffusivity values of MSH imply that the conventional conductive heating is less effective and inefficient for the thermal treatment of MSH.
Estimation in the Presence of Heteroskedasticity of Unknown Form: A Lasso-based Approach
Authors: González-Coya Emilio , Perron Pierre 
Published: May 2023

Abstract
We study the Feasible Generalized Least-Squares (FGLS) estimation of the parameters of a linear regression model in the presence of heteroskedasticity of unknown form in the errors. We suggest a Lasso based procedure to estimate the skedastic function of the residuals. The advantage of using Lasso is that it can handle a large number of potential covariates, yet still yields a parsimonious specification. Using extensive simulation experiments, we show that our suggested procedure always provide some improvements in the precision of the parameter of interest (lower Mean-Squared Errors) when heteroskedasticity is present and is equivalent to OLS when there is none. It also performs better than previously suggested procedures. Since the fitted value of the skedastic function falls short of the true specification, we form confidence intervals using a bias-corrected version of the usual heteroskedasticity-robust covariance matrix estimator. These have the correct size and substantially shorter length than when using OLS. Our method is applicable to both cross-section (with a random sample) and time series models, though here we concentrate on the former.
Editors’ Perceptions and Views on Journal Quality: The Case of Iran’s Editors-in-Chief
Authors: Ghane Mohammad Reza 
Published: May 2023

AbstractThe study aimed to determine the perceptions and views of Iranian editors about the quality of journals, articles, the responsibilities of the editorial team, review and the review process, copyright and intellectual property, consequences of open access (OA), and influential factors in the scientific life cycle of a journal. The study adopted a qualitative approach using interviews. Respondents included 13 editors of journals. Purposive and snowball sampling methods were used for the interview. The results showed that the editor’s main tasks were to supervise the reviewers’ performance, initially control the article, and send it to the reviewers. Participants believed that compliance with professional standards was the main factor influencing the scientific quality of publications. Their understanding of the ethical codes includes impartiality and confidentiality in evaluation and publication. In light of the fact that reviewers often perform superficial reviews, the editors viewed them as poor-quality. They stated that intellectual property is not valued and observed in many cases. Some participants mentioned the negative consequences of open access (OA). However, they think OA bears more positive than adverse outcomes. Observance of these factors is ultimately essential for the survival of a scientific journal.

A chiral inverse Faraday effect mediated by an inversely designed plasmonic antenna
Authors: Mou Ye , Yang Xingyu , Gallas Bruno , Mivelle Mathieu 
Published: May 2023

Abstract
The inverse Faraday effect is a magneto-optical process allowing the magnetization of matter by an optical excitation carrying a non-zero spin of light. This phenomenon was considered until now as symmetric; right or left circular polarizations generate magnetic fields oriented in the direction of light propagation or in the counter-propagating direction. Here, we demonstrate that by manipulating the spin density of light in a plasmonic nanostructure, we generate a chiral inverse Faraday effect, creating a strong magnetic field of 500 mT only for one helicity of the light, the opposite helicity producing this effect only for the mirror structure. This new optical concept opens the way to the generation of magnetic fields with unpolarized light, finding application in the ultrafast manipulation of magnetic domains and processes, such as spin precession, spin currents and waves, magnetic skyrmion or magnetic circular dichroism, with direct applications in data storage and data processing technologies.
Eine römische Villa im Barbaricum, 300 km vom Limes entfernt? Erste Forschungsergebnisse zur „Römischen Station“ bei Buzovycja
Authors: Petrauskas Oleg , Bondar K. , Didenko S. , Avramenko M. 
Published: May 2023

ZusammenfassungIn den Jahren 2020–2021 wurde bei Buzovycja (Ukraine, Černivci Gebiet) ein Fundplatz klar römischen Ursprungs entdeckt. Erste Feldforschungen im Jahr 2020 ließen bereits die Existenz von Gebäuden vermuten, die nach römischer Bautradition errichtet wurden. Auf der Geländeoberfläche zeichneten sich an mehreren Stellen spezifische architektonische Überreste ab. Solche Anhäufungen enthielten neben den üblichen Funden der Černjachiv-Kultur auch Ziegelstein-, Mörtel- und Steinfragmente. Nach den Ergebnissen einer 2021 durchgeführten geomagnetischen Messung wurde für Probegrabungen eine vielversprechende Anomalie im zentralen Teil der Siedlungsstelle ausgewählt. Die Hauptaufgabe dann erfolgten archäologischen Ausgrabungen bestand darin, den architektonischen Typ des Objekts zu bestimmen und diesen zu datieren. Die Ausgrabung brachte einen Gebäudebereich zu Tage, der aus Ziegeln, Steinen und Kalkmörtel errichtet wurde. Die Breite des Gebäudes betrug ca. 9,3 m, die mögliche Länge kann auf ca. 20 m geschätzt werden. Der freigelegte Gebäudeboden befand sich 1,4 m tief unter dem heutigen Oberflächenniveau und bestand aus mit Kalkstein angereichertem wasserdichtem Estrichmörtel.Im Nordteil des Gebäudes konnten auf dem Betonboden drei runde Ziegelsteine entdeckt werden, von denen eine an Ort und Stelle fixiert wurde. Stellenweise fanden sich komplette Ziegelblöcke, die bis zu vier Lagen zählten und mittels Kalkmörtel verbunden waren. Im Gebäude konnten eine Reihe von Funden geborgen werden. Dazu zählte Černjachiv-Keramik, Forlimpopoli-Amphoren, Amphorenständer, Glasperlen, eine Eisenkette und weitere Objekte mehr. Die Analyse der Funde und der Gebäudereste erbrachte, dass das Gebäude in spätrömische Zeit datiert (3.– Mitte 5. Jahrhundert n. Chr.). Die geborgenen Reste der Baukeramik und der Mörtel weisen darauf hin, dass es in römischer Architekturtradition errichtet wurde. Das Vorhandensein rechteckiger und runder Ziegelblöcke in einer Zerstörungsschicht deuten darauf hin, dass das Gebäude ein Hypocaustum hatte. Die sonstigen archäologischen Funde aus der Fundstelle Buzovycja-1 gehören hauptsächlich zur Černjachiv-Kultur. Gedeutet wird der Gesamtbefund nach gegenwärtigem Untersuchungsstand als einheimische Siedlung mit in diesem errichteten Gebäude in römischer Bautradition.

Authors: Gad Yasser H. , Ahmed Nehad A. , El-Nemr Khaled F. 
Published: May 2023

Abstract
In this work, polymeric composite films were fabricated utilizing stable, non-toxic, soluble, low-cost, good mechanical, and biocompatible polymers such as CMC and PVA with the waste of one of the most current fruits consumed worldwide banana peel waste (BP) as a filler. Sequences of carboxymethyl cellulose/polyvinyl alcohol/banana peel (CMC/PVA/BP) composite films with various amounts of BP utilizing eco-friendly technique (electron beam) (EB) irradiation were prepared to eliminate common hazardous organic pollutants such as methylene blue (MB) dye from its solutions. Physical characteristics like; swelling and gel % were examined. The chemical structure, thermal stability, and surface morphology were examined utilizing FT-IR, TGA, DSC, XRD, EDX, and SEM. Additionally, the UV/Vis spectroscopy study was investigated to study the impact of the various parameters such as irradiation, contact time, pH, temperature, adsorbent dosage, and initial concentration on removal efficiency % of MB dye onto the prepared composite films. The adsorption process fitted with the Langmuir model, pseudo-second-order kinetic model, endothermic, favorable, and spontaneous. The adsorption capacity of MB dye onto the CMC/PVA/BP composite film was 19.6 mg/g at the optimum conditions: irradiation dose = 20 kGy, contact time = 120 min, pH = 10, temperature = 25 °C, adsorbent dosage = 0.1 g and initial conc. = 10 mg/L.
Experimental study on the influence of high-frequency vibratory mixing on concrete performance
Authors: Wu Zhao , Rongfang Wang 
Published: May 2023

Abstract
The method and parameter of mixing are crucial to the quality of concrete, and ordinary vibratory mixing is beneficial to the performance of concrete, which has been explored in numerous studies. In order to study the influence of high-frequency vibratory mixing on the performance of concrete more accurately, ordinary concrete C40, C50 steel fiber concrete, and C60 high-strength concrete are selected to make reach experiments in the article. After determining the optimum mixing ratio, the contrast experiment on forced mixing and high-frequency vibratory mixing (which at a given frequency) was operated first, which is for studying the improvement of workability and mechanical properties of concrete by vibratory mixing and then exploring the change of concrete performance under different vibration frequency in slump test, compressive strength test, and freeze–thaw test. The results indicate that compared with forced mixing, the compressive strength and splitting tensile strength of concrete all have been proposed in different ages (3 days, 7 days, and 28 days) with vibratory concrete mixing, and C50 steel fiber concrete has the highest compressive strength improvement rate. There is a deviation in the mechanism of concrete in different ages, which is affected by high-frequency vibration. But in the context of the whole test, high-frequency vibratory mixing is helpful for the working properties, mechanical properties, and durability of the concrete. Within the scope of the frequency values in the test, the best vibration frequency for C40 ordinary concrete is 190 Hz, and in 212 Hz, C50 steel fiber concrete and C60 high-frequency concrete present the best performance.

Published: May 2023

Abstract
This article deals with the oft-debated identification of Moresheth Gath, mentioned in the book of Micah as the prophet’s hometown. Based on comprehensive analysis of texts from the early Christian period, the Amarna archive and the book of Micah, the authors claim for the first time that Moresheth Gath is to be identified with Azekah, the economically and strategically important site in the western Shephelah. »Moresheth Gath« was the old name of the site before becoming part of Judah at the end of the 9th century BCE, when the Judahite rulers renamed it »Azekah«.

Published: May 2023

Abstract
Die Resilienz von Lieferketten gewinnt für produzierende Unternehmen in Zeiten schwerer Störungen durch Krisen massiv an Bedeutung. Die Auswahl von Zulieferern ist ein zentraler Aspekt bei dem Aufbau einer resilienten Lieferkette. Aktuell fehlt jedoch eine ganzheitliche Methode zur Auswahl von Lieferanten unter Berücksichtigung der Resilienz. In diesem Beitrag wird daher ein Forschungsprojekt vorgestellt, das die Entwicklung eines Bewertungsmaßes für die Resilienz im Kontext der Zuliefererauswahl zum Ziel hat. Dabei sollen die vorhandene Resilienz aus der Sicht des Zuliefererunternehmens und die benötigte Resilienz aus der Sicht des auswählenden Unternehmens berücksichtigt werden.
Level of Coordination in der Fabrikplanung
Authors: Schäfer Simon F. , Lenz Lisa , Neuhäuser Thomas 
Published: May 2023

Abstract
Building Information Modeling (BIM) in der Fabrikplanung wird in der Praxis immer häufiger angewendet und aufgrund der positiven Erfahrungen auch in Richtlinien sowie Standardisierungsarbeit weiterentwickelt. Hierbei bildet die Methodik BIM die Brücke zwischen den beiden Fachdomänen Produktionssystems- und Bauplanung sowie der Projektumsetzung. Durch die Integration der digitalen BIM-Modelle entsteht bereits frühzeitig ein ganzheitlich virtuelles Abbild der Fabrik. Die zwischen den Fachdomänen notwendige Koordination während der Modellerstellung und der späteren -pflege ist bislang nicht standardisiert, sondern erfolgt projektspezifisch. Als Beitrag zur systematischen Digitalisierung der Fabrik sowie deren Planung wird in diesem Beitrag die Koordination der BIM-Modelle und die damit verbundene Modellqualität als Level of Coordination in Ergänzung zum Modellfertigstellungsgrad (Level of Development) beschrieben. Dieser Beitrag ist der erste von zwei Teilen.
Developing an Annual Training Program for the Mixed Martial Arts Athlete
Authors: Huldi Francis J. , Cisar Craig J. 
Published: May 2023

ABSTRACT
Mixed martial arts (MMA) is a multidimensional combat sport combining various forms of grappling and striking methodologies. The sport challenges the strength and conditioning professional because of the conflicting metabolic demands, high degree of variability, and a lack of a fixed competitive schedule. The existing literature identifies the need for highly developed neuromuscular qualities and high aerobic and anaerobic capacities. Although previous research has identified the physiological profile of a high-level MMA athlete, there is limited peer-reviewed research identifying the most optimal periodization strategy to improve performance. Furthermore, there seems to be no existing literature investigating the implementation of velocity-based training (VBT). This training methodology uses movement velocity to assign training loads to mitigate fatigue and improve strength and power adaptations. Existing literature on VBT suggests that it is a superior method of assigning training load compared with traditional percentage-based training. Therefore, this article serves to identify the physiological profile of the MMA athlete, outline VBT, and provide a guideline for designing an MMA strength and conditioning program to optimize performance using VBT.
Medium- and time-related effects on hypothermic storage of rat testicular cells

Published: May 2023

Testicular samples obtained for fertility preservation often need to be transported between clinics. This study aimed to mimic this short-term hypothermic storage (4–8°C) and explore the impact of these conditions and the transport medium composition on prepubertal rat testicular tissue samples. Testicular tissue samples obtained from 7 days post-partum rats were transferred to six compositionally different basal culture media and a balanced salt solution, which had been kept at 4–8°C prior to transfer. The samples were preserved for either 12 or 24 h in these hypothermic conditions. The potential effects of the short-term storage were evaluated by assessing the morphology, measuring the testosterone levels by radioimmunoassay and analysing 96 genes with TaqMan Low-Density Arrays. Levels of gene expression related to energy, apoptosis, and angiogenesis pathways were altered after hypothermic storage for 12 and especially 24 h. We observed only minor differences in gene expression profiles for germ and testicular somatic cells and no differences in tissue morphology and testosterone production levels. Short-term hypothermic storage of testicular tissue with a maximum duration of 24 h does not affect the overall expression profile of testicular cell-specific genes; however, in a minor way, it affects the expression of specific cellular genes.

Lay summary
Male fertility depends on the proper functioning of cells which develop into reproductive cells. Due to an increasing number of childhood cancer survivors suffering from treatment-related fertility problems, as well as recent reports showing a dramatic decrease in sperm counts over the last decades, male fertility preservation has become an important research topic. To date, there is no method to restore fertility for men who are not able to produce sperm. One promising method to preserve the potential fertility of these patients is freezing tissue or cells from the testicles for future fertility treatments. A critical phase in freezing testicular tissue or cells is the time between removing the tissue from the testicles and freezing it. To better understand the impact of this phase on the quality of the testicular tissue, we used the testes of rats as a model for our research. We found that cooling testis tissue has only minor effects on the expression of genes that are important for testis function.
Defending Christianity from the ‘rainbow plague’
Authors: Baran Dominika 
Published: May 2023

Building on previous work on the anti-genderism register and moments of enregisterment, and adopting the Discourse-Historical Approach with its notion of topoi as an argumentation device used by right-wing populists, this article examines how the Catholic Church and right-wing politicians and media have mobilised against the alleged threat of ‘LGBT/gender ideology’ in Poland. Based on the analysis of 70 texts including homilies, political speeches, news articles and interviews, the article identifies three content-related topoi that are relayed across various anti-genderist actors. Together, these topoi and their repeated reuptake help to construct a historicised narrative of Poland as the defender of Christianity and of Europe, and to legitimise different actors’ anti-LGBT campaigns as they pursue their particular agendas. The article makes a contribution to exploring the processes through which the globally circulating anti-genderism register operates in a specific local context.
