A Digital Concordance of Etruscan, Faliscan, and Early Latin Inscriptions from Etruria
Authors: Burman Annie C. 
Published: May 2023

Abstract
Epigraphic concordances (lists which give corresponding references for two or more epigraphic corpora) are an indispensable resource for any scholar whose work relates to inscriptions. Despite their usefulness, there are inherent issues with conventional concordances of the type found at the back of epigraphic corpora. This article presents a digital concordance for Etruscan, Faliscan and early Latin inscriptions from Etruria. The concordance, which is contained in a CSV file, is downloadable from the repository Zenodo, and allows for both free-text searches and reordering according to each included corpus. The digital format allows for future revision and correction; an email address dedicated to feedback from the scholarly community has been set up. The corpora included in the concordance are chosen to make the concordance a comprehensive resource for both contemporary scholarly use and study of the history of epigraphy.
The Speaker Election in the 118th Congress: A Procedural Review
Authors: Glassman Matt 
Published: May 2023

Abstract
The election of a new Speaker of the House of Representatives for the 118th Congress in January 2023 stretched on for several days and 15 roll call votes—the longest contested Speaker election in modern congressional history. This article proves a two-part analysis of this unusual event. First, it reviews the procedural practice of the House for its organization at the beginning of each Congress. Second, it analyzes the operational and strategic conduct of the election, with an eye not only on the individual Members-elect and party factions operating within it, but also on the role of the non-partisan House officers managing the proceedings.

Characterization of Jordan two-sided centralizers and related maps on triangular rings
Authors: Hosseini Amin , Ali Shakir , Karizaki Mehdi Mohammadzadeh 
Published: May 2023

Abstract
The main goal of this paper is to characterize Jordan two-sided centralizers, Jordan centralizers and related maps on triangular rings without identity. As an application of our main theorem, we characterize Jordan generalized derivations on triangular rings. Precisely, we prove that every Jordan generalized derivation on a triangular ring is a two-sided generalized derivation. As consequences, and apart from proving the other results, many known theorems can be either generalized or deduced.

Published: May 2023

Abstract
Insecticides kill mosquitoes but damage other animals including humans. Eco-friendly metal nanoparticles may be a plant-based pesticide for vector control. Here, the copper nanoparticles (Cu NPs) synthesized from Nepeta catarialeaves have been investigated for their antibacterial and larvicidal properties. Fourier transforms infrared spectroscopy demonstrated that biochemicals reduced and stabilized nanoparticles by shifting peaks from 1,049 to 1,492 cm−1, and ultraviolet–visible spectrometry proved that produced Cu NPs had a peak at 550 nm. Transmission electron microscopic and scanning electron microscope showed that the particles are spherical and 23–29 nm in size. X-ray diffraction analysis shows that Cu NPs are crystalline. At a 100 µg·mL−1 concentration, Cu NPs exhibited a higher percentage of inhibition in the order of Escherichia coli ≫ Enterococcus faecalis ≫ Staphylococcus aureus. The lethal concentration (LC50) of the Cu NPs against the larvae of Aedes aegypti, Anopheles stephensi, and Culex quinquefasciatus was determined to be 60.63, 56.58, and 54.32 µg·mL−1, respectively. This ground-breaking study describes the biological production of Cu NPs utilizing N. cataria leaf extract for the first time. Based on these findings, the bio-synthesized Cu NPs and the aqueous extract of N. cataria may provide a potential alternative method for managing these vector populations.

Authors: Yan Li , Yan Zeyao , Chen Jiang , Chen Zhangjing , Lei Yafang 
Published: May 2023

Abstract
Vanillin is an antifungal and environmentally friendly compound. In this study, vanillin and silica microcapsules (VSM) were microencapsulated using the sol-gel method and then impregnated into wood. Scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDXA) and transmission electron microscopy (TEM) were used to characterize the morphological structure and distribution of VSM in wood. Fourier transform infrared spectroscopy (FTIR) was used to study the intermolecular interactions between VSM and wood. The antifungal performance of the VSM-treated wood was evaluated. The study revealed that VSM had good sustained-release performance and decay resistance. Mass losses of VSM-treated wood after leaching and exposure to Trametes versicolor (L.) Quel. and Gloephyllum trabeum (Pers.) Murrill decreased from mass losses of 20.8 % and 15.9 % of the control group to 9.2 % and 6.4 %, respectively. VSM treatment disrupted the mycelium of T. versicolor and G. trabeum, inhibited their respiratory metabolism, and the ligninase-laccase enzyme activity of T. versicolor. Meanwhile, MOR and MOE of VSM-treated wood were 96.7 MPa and 12.3 GPa which were 28.8 % and 11.5 % higher than the control group, respectively.

N/GaN superlattice. Thermal conductivity reduction is one recent effort to improve thermoelectric device efficiency because a small reduction in thermal conductivity can enhance the figure of merit significantly. Quantum size effect and thermal boundary resistance are responsible for this reduction. The theoretical results demonstrate that the interfacial polarization electric field modifies acoustic phonon properties through elastic moduli and phonon group velocity as a result of the inverse piezoelectric effect. This enhances phonon scattering and thermal boundary resistance. Consequently, the thermal conductivity of the superlattice is reduced. Room temperature thermal conductivity is found to be 2.94 (3.35) W m−1 K−1 for In

IMA J. Appl. Math. 86 2021, 3, 604–630], a novel reconstruction scheme has been developed for the solution of the inclusion problem in the inverse conductivity problem on the basis of a weighted self-guided regularization process generalizing the total variation approach. The present work extends this concept by implementing and investigating its applicability in the two-dimensional elasticity setting. To this end, we employ the framework of the reconstruction of linear and isotropic elastic structures described by their Lamé parameters. Numerical examples of increasingly challenging geometric complexities illustrate the enhanced accuracy and efficiency of the method.

Nihilism Lost and Found: Brassier, Jonas, and Nishitani on Embracing and/or Overcoming Nihilism
Authors: Lehner Andrea , Restrepo Felipe Cuervo 
Published: May 2023

Abstract
This essay confronts Ray Brassier’s vindication of nihilism with other two important but frequently underexamined philosophical attempts to overcome nihilism: Hans Jonas’ and Keiji Nishitani’s. By putting these different takes on nihilism into dialogue, it explores some blind spots in Brassier’s position, as well as some of the practical consequences, for our current planetary situation, of undertaking a radical divorce between the normative and the natural that results from his radical nihilism. The article opts for a more moderate acceptance and eventual self-overcoming of nihilism, according to which, even if natural entities are indifferent to human reasons and meanings, this does not entail that nature is bereft of a human-independent normative dimension. In other words, the essay argues that care must be taken not to confuse criticisms of an anthropocentric conception of reasons and meanings with the belief that meaning is completely absent from the natural world. Thus, the central contention of the article is that, given our current climate and ecological catastrophe, one of the most pressing tasks of contemporary philosophy is to understand normativity in non-anthropocentric ways, so that humans are no longer considered as the only entities that respond to normativity. Such an attitude conceives humans as estranged normative creatures amidst a meaningless, indifferent natural world, toward which they would have no ethical responsibilities. The essay finishes by suggesting ways in which to develop an account that does not fall into this ethical vacuum.
Process intensification using immobilized enzymes
Authors: Bolat Sera , Greifenstein Raphael , Franzreb Matthias , Holtmann Dirk 
Published: May 2023

Abstract
The application potential of enzymes is undoubtedly very high. However, despite the very large number of different enzymes and enzyme activities, the number of industrial enzyme processes is comparatively small. The particular challenge often lies in transferring promising laboratory processes to an industrial scale. Here, the required performance parameters, such as enzyme stability or productivity, must be achieved. On the one hand, this can be achieved by improving the enzymes. On the other hand, the key performance indicators can often only be achieved by using technical systems in the sense of process intensification. In enzymatic processes, immobilization of enzymes is often the means of choice to enable technical processes. The aim of this article is to outline the most important enzyme immobilization methods and to summarize the most important performance indicators of immobilized enzymes. Finally, the different immobilization methods and performance indicators are compared in a case study with unspecific peroxygenase.

Investigation of Measurement Capability for Charpy V-Notch Specimens Using Typical Measurement Practices
Authors: Conley David A. , Pline Timothy R. 
Published: May 2023

Abstract
This paper investigates the capability of laboratories and industrial entities to measure the critical dimensions of the Charpy V-notch specimen, as defined in ASTM E23, Standard Test Methods for Notched Bar Impact Testing of Metallic Materials. Notched impact testing is commonly used to evaluate the impact strength and behavior of metals under impact loads at various temperatures. The ASTM Subcommittee E28.07 on Impact Testing became concerned that measuring the dimensions of the V-notch, which is considered critical to the test results, may be less achievable than is generally assumed. An interlaboratory study (ILS) was conducted with ASTM member entities to evaluate the ability of laboratories with various measurement techniques to accurately measure the critical dimensions. This paper evaluates the results of the ILS, which found that the community of laboratories surveyed could not measure all of the critical dimensions with sufficient accuracy to properly reject unacceptable notches. Conclusions and recommendations are provided to improve laboratory performance and provide guidance that may be issued in a revision to ASTM E23. The authors would like to thank the National Institute of Standards and Technology for providing statistical evaluations of the sample data and for the laboratories who participated in the ILS.
Very High Cycle Fatigue Data Acquisition Using High-Accuracy Ultrasonic Fatigue Testing Equipment
Authors: Schönbauer Bernd M. , Fitzka Michael , Jaskari Matias , Järvenpää Antti , Mayer Herwig 
Published: May 2023

Abstract
Fatigue testing at ultrasonic frequency is a powerful method for rapid generation of high and very high cycle fatigue data. High accuracy of cyclic loading is the basis for reproducible test results, which can be obtained with closed-loop control of vibration amplitude and resonance frequency. Self-heating of test specimens can be suppressed by intermittent (pulse-pause) loading. In the present work, the high-accuracy ultrasonic fatigue testing equipment developed at the University of Natural Resources and Life Science, Vienna (BOKU) is described, and systematic investigations are presented that demonstrate the effects of cycling frequency, specimen size, and intermittent loading. Data obtained with additively manufactured (AMed) austenitic stainless steel 316L at 19 kHz are compared with electromagnetic resonation test results measured at 90 Hz. No influence of cycling frequency on fatigue lifetimes and fatigue limit was found when specimens of comparable size were used for tests at 19 kHz and 90 Hz. In contrast, the use of as-built specimens with smaller testing volume resulted in an increase in cyclic strength, demonstrating a size effect on fatigue properties. Polishing the surfaces of AMed specimens increased the fatigue limit by a factor of two. Furthermore, ultrasonic fatigue tests with intermittent loading and four different pulse lengths as well as continuous cycling were performed. The tests were conducted with wrought aluminum alloy 7075-T651 and with specimens containing small artificial surface defects. Similar lifetimes were measured in all testing series. Moreover, the same fatigue limit is found for all pulse lengths and for continuous cycling. This demonstrates that pulsed loading is a most suitable method to avoid specimen heating at ultrasonic frequency and that there is no influence on measured fatigue properties if ultrasonic loading is appropriately controlled. Measurement artifacts could be identified and avoided by measuring and recording all load amplitudes during ultrasonic fatigue tests.

Published: May 2023

Central Java is one of the provinces with the highest number of positive Covid-19 cases in Indonesia, with 46,903 positive infected cases, with a death rate of 2,110 people (4.49%). During the COVID-19 pandemic, community activities decrease, especially during the fasting month. Their diet has also changed. This study aimed to describe and analyse the relationship between nutritional intake and physical activity on people's sleep quality during the fasting month during the COVID-19 pandemic. The benefit of this research is to provide information on factors related to people's sleep quality, so as to improve public health. The novelty of this research is on aspects of physical activity, and people's sleep quality during the fasting month during the covid-19 pandemic. This research method is observational using a cross-sectional approach. The research was conducted during the fasting month (Ramadan 2021) to find out the nutritional intake, physical activity, and quality of people's sleep while fasting amid the COVID-19 pandemic. This study was attended by 520 respondents who were willing to fill out a questionnaire distributed via Googleform. Respondents in this study were limited to people who live in Central Java. The selection of respondents using the cluster sampling technique and then the snowball method. The questionnaires were the Pittsburgh Sleep Quality Index (PSQI), IPAQ and DQI. The results showed no relationship between physical activity and slept quality during the fasting month (p : 0.402). There is a relationship between food consumption, sleep quality (p: 0.0001), and physical activity (0.007) during the fasting month.
