Abstract
A 6.9 magnitude earthquake hit Menyuan County, Haibei Prefecture, Qinghai Province, at 01:45 PM Beijing time on January 8, 2022 (17:45 PM GMT time on January 7, 2022). To explore the magnitude of the earthquake deformation and the affected area, this work combined optical remote sensing interpretation, interferometric synthetic aperture radar (InSAR) coseismic deformation extraction, and field surveys for research and analysis. Relying on the high-resolution Earth observation system of the Qinghai Remote Sensing Center for Natural Resources, high-resolution GF1D, GF2, and TRIPLESAT optical remote sensing images were acquired immediately after the earthquake. The airborne triangulation encryption method was used to carry out orthographic correction, fusion, and mosaic processing of digital orthophoto map (DOM) and digital surface model (DSM) images, and first-hand optical remote sensing images of the disaster areas were obtained. Based on differential InSAR (D-InSAR), small baseline subset InSAR (SBAS-InSAR) and lifting rail fusion methods, the coseismic deformation field and deformation rate of the lifting rail direction were obtained by using Sentinel-1A data processing before and after the earthquake. Combined with optical interpretation, InSAR deformation, and field investigation, the results show that the deformation trend of the line of sight (LOS) images to the north and south of the ascending and descending orbits show an obvious opposite trend. The surface shape variables are −50 to 45 cm and −65 to 72 cm, respectively, and the deformation rate before the earthquake reached 25 cm/year. The deformation field characteristics show that the earthquake was mainly due to thrust, and the coseismic deformation field fractured along the WNW‒ESE direction with a length of approximately 33 km. The areas affected by 10 mm, 20 cm, and 50 cm deformation magnitudes in the whole earthquake area were 975.14, 321.10, and 38.55 km2, respectively. Within 20 km, there were two main affected townships, namely, Sujitan Township and Huangcheng Mongolian Township. Within 50 km, there were four main affected towns and townships, namely, Sujitan Township, Mongolian Township of the Imperial city, Qingshizui town, and Haomen town.

Abstract
Graphene oxide (GO) and reduced graphene oxide (rGO) nanoparticles were synthesized using 40 mL of lemon juice extract as a reducing agent. The synthesized nanoparticles were characterized using various analytical techniques, including UV–visible spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. The results confirmed the successful synthesis of GO and rGO nanoparticles with varied sizes and shapes. The synthesized nanoparticles were tested for their antimicrobial activity against a range of bacterial and fungal strains, including Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Candida albicans, Fusarium oxysporum, and Aspergillus flavus. Multiple concentrations of GO and rGO nanoparticles were tested, and it was observed that 100 µg·mL−1 of both GO and rGO showed the highest inhibitory effect against bacterial and produced zones of inhibition of 17.66 mm, 18.67 mm, and 17.88 for E. coli, S. aureus, K. pneumoniae and 20.33, 22.45, and 21.34 mm for C. albicans, F. oxysporum, and A. flavus. Comparatively, GO performed well as compared to rGO regarding antimicrobial activity. The synthesized nanoparticles exhibited significant antimicrobial activity against various bacterial and fungal strains and have the potential to be developed as novel antimicrobial agents.

Published: February 2024

Abstract
For several years, the significance of gaseous energy sources (e. g. liquified natural gas and hydrogen) has been increasing worldwide due to environmental and climate policy requirements. Storage and transportation of the liquids occur under cryogenic conditions. This results in specific requirements for the mechanical properties of the materials used at cryogenic temperatures. Nowadays, cold-tough, high-nickel austenites and martensitic steels of type X8Ni9 are used for such purposes. While austenitic materials offer good processing properties, they are not attractive due to their comparatively low strength and high costs. Welding martensitic steel with commonly used nickel-based additives significantly impacts processing quality and process automation due to high magnetic remanence. Additionally, the increased requirements for the storage of liquid hydrogen regarding low-temperature toughness push the conventional low-temperature materials to their limits. A potential solution to the identified challenges can be achieved by using medium- and high-manganese austenitic steels. Within the scope of this work, the medium-manganese steel X2CrMnNiN1775 (1.4371) is investigated as an economical substitute for the conventionally used materials in cryogenic applications. Considering the relevant qualification requirements for welded joints and welding additives, submerged arc welded joints are investigated and their applicability under cryogenic operating temperatures is demonstrated.
Automorphic word maps and the Amit–Ashurst conjecture
Authors: Kishnani Harish , Kulshrestha Amit 
Published: February 2024

Abstract
In this article, we address the Amit–Ashurst conjecture on lower bounds of a probability distribution associated to a word on a finite nilpotent group.
We obtain an extension of a result of [R. D. Camina, A. Iñiguez and A. Thillaisundaram, Word problems for finite nilpotent groups, Arch. Math. (Basel)
115 (2020), 6, 599–609] by providing improved bounds for the case of finite nilpotent groups of class 2 for words in an arbitrary number of variables, and also settle the conjecture in some cases.
We achieve this by obtaining words that are identically distributed on a group to a given word.
In doing so, we also obtain an improvement of a result of [A. Iñiguez and J. Sangroniz, Words and characters in finite 𝑝-groups, J. Algebra
485 (2017), 230–246] using elementary techniques.
Scaling factors for CANDU reactor waste: how reliable are they?
Authors: Greening Frank R. 
Published: February 2024

Abstract
This paper presents the results of a study of the use of the scaling factor method for the determination of the activities of the difficult to measure radionuclides – H-3, C-14, Ni-63, Sr-90, Pu-239/240 and Pu-214 – observed in CANDU radioactive waste. Twenty-six smear samples collected in the vault of Bruce Unit 1 during its refurbishment in the period 2009 to 2012 are used as surrogates for radioactive waste packages generated by the operation, maintenance, refurbishment and decommissioning of a CANDU reactor. A detailed analysis of the data presented in this paper shows that: (i) the activities of H-3 and C-14 cannot be reliably determined by the scaling factor method, and (ii) the activities of Ni-63, Sr-90, Pu-239/240 and Pu-214 estimated by the scaling factor method are typically in agreement with the measured activities to within only an order of magnitude of their true values. It is recommended that activities of CANDU rad-waste samples derived by the scaling factor method should be reported to only one significant figure to better reflect the limited precision and accuracy of this method.
(Integrations-)Chancen durch Kompetenzerwerb im Sportverein – eine Perspektive auf ehrenamtliches Engagement von Menschen mit Migrationshintergrund
Authors: Olmesdahl Kim , Haut Jan , Müller Lasse , Heim Christopher 
Published: February 2024

Zusammenfassung
Ehrenamtliches Engagement im Sportverein bietet viele Lern- und Entwicklungschancen. So kann es auch die (Sozial-)Integration von Menschen mit Migrationshintergrund (MmMH) unterstützten. Diese sind allerdings in ehrenamtlichen Positionen seit Jahren unterrepräsentiert. Der vorliegende Beitrag analysiert mit Bezug auf die zugrunde liegenden Lernprozesse, welche Entwicklungs- und Integrationspotentiale für MmMH im ehrenamtlichen Engagement gesehen und von den Engagierten angestrebt werden. Die leitfadengestützten Interviews (N=10) sowie die Gruppendiskussion (N=5) weisen zwar auf Bedingungen hin, die den Weg ins Ehrenamt für MmMH erschweren und die besagte Unterrepräsentanz begründen. Sie bestätigen aber auch, dass im ehrenamtlichen Engagement viele alltagsrelevante Kompetenzen erworben werden können. Sportvereine könnten diesen Mehrwert proaktiver kommunizieren, um mehr MmMH den Zugang zum Ehrenamt und zu den damit verbundenen Möglichkeiten des Kompetenzgewinns zu eröffnen.
Finite element based dynamic analysis of a porous exponentially graded shaft system subjected to thermal gradients

Published: February 2024

Abstract
In modern applications, demand for the rotor shafts made of FGM has increased in aerospace, gas turbine and turbo jet engines due to its improved dynamic characteristics at elevated temperatures. The dynamic vibration response of a functionally graded Jeffcott rotor-bearing system with induced porosities has been studied for non-uniform porosity distributions. The functionally graded (FG) shaft’s radial direction exhibits continuous variation in the material qualities. The FG rotor’s cross-sectional material properties have been graded using the exponential law. The temperature gradients have been considered to be varied across the cross-section based on exponential temperature distribution. For the first time, using the FE method, it has been possible to study the impact of induced porosities on the free vibration frequencies and steady-state vibration responses of the functionally graded rotor-bearing system. This has led to the development of a two-node porous functionally graded rotor element with uneven porosity distributions using the Timoshenko beam theory. It has been observed that the free vibration frequencies and the FG rotor-bearing system critical speeds are affected by increased porosity and thermal gradients. The frequency responses demonstrate that as temperature gradient and volume fraction of porosity rise, the FG rotor-bearing system’s critical speeds shift to the left.

Published: February 2024

Abstract
Ca3Ru3Zn13 was synthesized from the elements in a tantalum tube in a muffle furnace. The sample was annealed to 1123 K followed by slow cooling to enhance crystal growth. Ca3Ru3Zn13 was characterized through a Guinier powder pattern. The structure was refined from single crystal X-ray diffractometer data: new type, Pbcn, a = 522.92(5), b = 1792.72(14), c = 2789.6(2) pm, wR2 = 0.0590, 3451 F
2 values, 177 variables. One can describe the Ca3Ru3Zn13 structure by a stacking of closest packed layers of compositions Ca6Zn10, Ca6Zn12 and Ru6Zn15. The calcium atoms have high coordination numbers: Ca1@Zn13Ru3Ca2, Ca2@Zn15Ru4Ca, Ca3@Zn15Ru4Ca and Ca4@Zn15Ru4Ca. The shortest interatomic distances occur between the ruthenium and zinc atoms (255–273 pm). The Ru1@Zn8, Ru2@Zn10 and Ru3@Zn8 polyhedra condense via common edges to the [Ru3Zn13] substructure which hosts the calcium atoms. The zinc substructure consists of 15 crystallographically independent zinc sites with a broader range of Zn–Zn distances (255–307 pm).

Abstract
The immune biological response systems and inflammation can be triggered by a number of things such as pathogens, damaged cells and toxic substances. In ethnomedicine, leaves of Lemon basil (Ocimum basilicum citriodorum) have been used for their health benefits. This study examines the anti-inflammatory properties of lemon basil stalks. In a GC/MS study, 24 plant-based bioactive compounds were identified. Comparing the activities in 24 compounds with the largest negative binding energy values helped us determine which compound was most active. It can be seen that only two compounds (Campstool and stigmasterol) with the highest binding energies interact with the 2QVD protein; consequently, the compound with the highest binding energy has superior anti-inflammatory activity. In quantum mechanics, electron energy difference between lowest-unoccupied molecular orbitals (LUMO) and highest-occupied molecular orbitals (HOMO) is described by the quantum-mechanical method, electronegativity (χ), electron affinity (A), global hardness (η), global softness (σ) and ionization potential (I) estimated from the optimized structure. Higher energy molecules are more reactive than other substances reported in this study.
„Vitis mystica”. Aspektychrystologii afektywnej traktatu o Męce Pańskiej św. Bonawentury
Authors: Kośla Romuald Henryk 
Published: February 2024

Based on the analysis of some aspects of the mystery of Christ contained by the Seraphic Doctor in the work of “Vitis Mystica”, it is possible to determine the profile of the Christological discourse. It is clearly mystagogical and mystical, revealing a typically experiential, and therefore affective formula. Divine realities, such as: the incarnation, the passion, the cross or the Sacred Heart of Jesus, are for Bonaventure a kind of „prisons” of love, they are above all open spaces through which God does not let himself be known, but rather met. According to his practical way of understanding all theology, Jesus Christ as Verbum Incarnatum et Crucifixum is and should be the center of man’s spiritual life.

Authors: Dziedzic Jan 
Published: February 2024

Universities of the third age have become very popular in Poland and in the world. As institutions dealing with lifelong learning, they have the appropriate competencies to ensure that the various needs of seniors are met. U3A, established at UPJPII in Kraków in 2011, is one of such programs, dynamically operating in Poland. It is aimed not only at increasing the level of general knowledge but also at the religious formation of the students. The university has a religious profile and implements a pastoral and educational program, that includes lectures and workshops in the field of the Bible and anthropology, ethics, theology, philosophy and history of the Church, as well as an educational and cultural program (religious tourism, theatre arts), that is meant as a form of creative support for seniors. Plenary lectures and seminar workshops are complemented with the offer of additional educational and developmental classes. They include foreign language learning, computer courses, tourism, sports and cultural activities. Thanks to our U3A, many elderly people have improved their self-esteem and sense of dignity. They have also learned how to overcome problems related to old age and barriers preventing them from full participation in social and parish life.
From Benign to Malignant: The Arrival of Pituitary Neuroendocrine Tumors (PitNETs)
Authors: Meagher Timothy 
Published: February 2024

Pituitary adenomas were recently reclassified as “neuroendocrine tumors,” and are now considered to be cancers. The evolution and justification for this change are described.
Critical illness policies, which currently provide coverage of pituitary adenomas under the “Benign Brain Tumor” provision must now be modified to reflect this new taxonomy. This change also prompts questions about the use of the words ‘benign’ and ‘tumor’ in critical illness policies.
Contribution of Cold Versus Climate Change to Mortality in London, UK, 1976–2019
Authors: Hajat Shakoor , Gampe David , Petrou Giorgos 
Published: February 2024

Objectives. To quantify past reductions in cold-related mortality attributable to anthropogenic climate change. Methods. We performed a daily time-series regression analysis employing distributed lag nonlinear models of 1 203 981 deaths in Greater London, United Kingdom, in winter months (November–March) during 1976 to 2019. We made attribution assessment by comparing differential cold-related mortality impacts associated with observed temperatures to those using counterfactual temperatures representing no climate change. Results. Over the past decade, the average number of cold days (below 8 °C) per year was 120 in the observed series and 158 in the counterfactual series. Since 1976, we estimate 447 (95% confidence interval = 330, 559) annual cold-related all-cause deaths have been avoided because of milder temperatures associated with climate change. Annually, 241 cardiovascular and 73 respiratory disease deaths have been avoided. Conclusions. Anthropogenic climate change made some contribution to reducing previous cold-related deaths in London; however, cold remains an important public health risk factor. Public Health Implications. Better adaptation to both heat and cold should be promoted in public health measures to protect against climate change. In England, this has been addressed by the development of a new year-round Adverse Weather and Health Plan. ( Am J Public Health. 2024;114(4):398–402. https://doi.org/10.2105/AJPH.2023.307552 )

Published: February 2024

This study investigates the difference between the utility of general higher education (GHE) and Islamic higher education (IHE), students' enrolment intention, and their correlation. Data were collected using questionnaires. The participants of this study were 753 students in South Kalimantan, Indonesia. Researchers used convenience and snowballing sampling techniques. Data analysis used the Wilcoxon Signed Rank Test and Spearman's correlation. This study proves that the level of utility and all its factors (economic and non-economic benefit, probability of success, and cost) differ significantly between GHE and IHE (Sig<0.05). Moreover, it was found that all factors correlate with enrolment intention (Sig<0.05). However, correlation coefficients indicate that the cost of GHE and IHE is the factor with the weakest correlation (p=0,139 and p=0.084) with enrolment intention. The strongest correlation with enrolment intention is the utility of GHE and IHE (p=0,597 and p=0.579) and the possibility of success in GHE and IHE(p=0,614 and p=0.530). This study offers practical recommendations for higher education institutions and suggests future research.
