Evaluating Wagner Oxidation Criteria for Protective Al2O3 Scale Formation in Ni-Based Superalloys
Authors: Wo J. W. X. , Hardy M. C. , Stone H. J. 
Published: June 2023

AbstractAn assessment is made of the Wagner transition criteria for predicting the formation of a continuous Al2O3scale in Ni-based superalloys. Predictions are compared with data from an experimental Ni-based superalloy as well as commercial superalloys for which published data are available. The methodology was generally successful in predicting the transition temperature of the commercial superalloys but underpredicted the transition temperature of the experimental superalloy by approximately 50–100 °C. The difference in the transition temperature of the experimental superalloy to form a continuous Al2O3scale is primarily attributed to a complex oxide subscale that increased the internal volume fraction of oxide and led to reduced oxygen ingress. The sensitivity and limitations of the methodology are discussed, and recommendations are made to refine the methodology to facilitate the interpretation of oxidation behaviour in polycrystalline Ni-based superalloys.

Authors: Preda Alberto , Carbone Federico , Tirandi Amedeo , Montecucco Fabrizio , Liberale Luca 
Published: June 2023

AbstractObesity epidemic reached the dimensions of a real global health crisis with more than one billion people worldwide living with obesity. Multiple obesity-related mechanisms cause structural, functional, humoral, and hemodynamic alterations with cardiovascular (CV) deleterious effects. A correct assessment of the cardiovascular risk in people with obesity is critical for reducing mortality and preserving quality of life. The correct identification of the obesity status remains difficult as recent evidence suggest that different phenotypes of obesity exist, each one associated with different degrees of CV risk. Diagnosis of obesity cannot depend only on anthropometric parameters but should include a precise assessment of the metabolic status. Recently, the World Heart Federation and World Obesity Federation provided an action plan for management of obesity-related CV risk and mortality, stressing for the instauration of comprehensive structured programs encompassing multidisciplinary teams. In this review we aim at providing an updated summary regarding the different obesity phenotypes, their specific effects on CV risk and differences in clinical management.

AbstractWater pollution is referred to as the introduction of exotic species into an ecosystem, which poses serious difficulties for both the environment and human health. As a result, water treatment has garnered a lot of interest in recent studies, particularly for dyes removal. In an effort to synthesize new photocatalysts with the highest potential for removing pollutants, photocatalytic degradation of two types of dyes; aniline blue, and malachite green by newly synthesized Ag(I), Ni(II), and Co(II) complexes photocatalysts has been investigated here. Ag(I), Ni(II), and Co(II) ions were used to interact with the novel imine ligand, HL, which was produced by condensing 3-acetylcoumarin, and sulfadimidine, in order to make the desired complexes. Different spectroscopic methods were used to properly characterize and confirm the structures of all synthesized compounds. The ligand, HL act as anionic tetradentate through the imine group (C=N), lactone carbonyl group (C=O), sulfonamide group (SO2NH), and pyrimidine ring nitrogen. The suggested formula of the synthesized complexes were [Ag2(L)(NO3)(H2O)3], [Co2(L)Cl3(H2O)].2H2O, and [Ni2(L)Cl3(H2O)].2H2O with a tetrahedral structure, and nonelectrolyte nature. Through optical studies and XRD measurements, all investigated compounds have the semiconductor nature and nano sizes. TGA-DTG/DSC techniques were utilized to thermal behavior study as well as assess some thermodynamic and kinetic parameters for all degradation stages. The geometry of the proposed structure of all new synthesized compounds was optimized by density functional theory (DFT) calculations. The BET surface area and the porosity data align well with the excellent photocatalytic performance for [Co2(L)Cl3(H2O)].2H2O complex toward the dyes degradation.

Published: June 2023

AbstractEven though game elements can increase motivation and engagement, they also might distract learners and thereby decrease performance and learning outcomes. In the current study, we investigated the effects of intrinsically integrated game elements on performance and learning outcomes. In a pre-post training study, 85 adult participants were randomly assigned either to the game-based or non-game-based training condition. Participants trained their fraction magnitude understanding with digital number line estimation tasks on five consecutive days (á 15–20 min). The learning outcomes were evaluated using a paper-based number line estimation task. While participants in both the game-based and non-game-based condition improved their fraction magnitude understanding from pretest to posttest, their improvement did not differ significantly. However, during the training, participants in the game-based condition responded more accurately but were slower than those in the non-game-based condition. The current results suggest that game elements might increase participants’ cognitive engagement and change their priorities or strategies (i.e., accuracy over speed) during learning. Nevertheless, better training performance did not lead to superior learning outcomes.

Published: June 2023

AbstractTo achieve a desired microstructure and minimize the thickness variation in rolled foils, researchers must understand the effects of foil fabrication process variables on microstructure evolution. We developed an integrated simulation of deformation and recrystallization that employs the finite element method (FEM) and the kinetic Monte Carlo (KMC) Potts model, respectively, to investigate microstructure evolution during multiple-pass hot rolling and heat treatment in polycrystalline U-10Mo fuel. Scanning electron microscopy and electron backscatter diffraction images of microstructures were directly used as input in FEM calculation of deformation, and the calculated strains were used to determine the driving force of nucleation and growth of recrystallized grains in the Potts model. Grain structures predicted by the Potts model were used to update the grain structure and material properties for FEM. Simulation alternated between FEM and the Potts model to simulate grain structure evolution during multiple rolling and heat treatments. The initial model parameters were determined by benchmarking the recrystallization kinetics against experimental data. Then, the model was applied to predict the grain structure evolution. Results showed that our model can capture the coupling between deformation and recrystallization and can quantitatively reproduce the observed U-10Mo recrystallization and grain growth kinetics. The simulation results demonstrated that the developed model can predict U-10Mo grain structures as a function of initial microstructure and foil fabrication parameters.
‘This is what it is like to be church’: the Church of Sweden’s conditions for work with newly arrived refugees
Authors: Vikdahl Linda , Gunnarsson David , Larsson Sofia 
Published: June 2023

AbstractMany newly arrived refugees suffer from mental health problems due to trauma. Research has shown that social participation after migration, such as taking part in social activities, networks and community work, is important for mental health and well-being. In Sweden, many civil society organisations, such as the Church of Sweden, take great responsibility for the establishment and integration of new arrivals. At the same time, the role of civil society organisations in the welfare society is not obvious, and the place of religious communities is sometimes challenged. Due to today’s growing secular and globalised society, the role of the Church of Sweden has changed. Its power has decreased, and the indications are that this will continue. There are also circumstances that point to the church having to adapt to the norms of secular society to have an impact. As the Church of Sweden fulfils an important function as a provider of welfare services, not least in work with newly arrived refugees, this article studies how the employees of the Church of Sweden feel about their conditions for this work and what guides it. It is based on a qualitative study of 19 interviews with employees in 4 different parishes.

Abstract
Introduction
The oncoplastic conservative surgery was developed as a natural evolution of traditional surgery, attempting to improve the therapeutic and aesthetic outcomes where tumor resection could be followed by not-adequate results. Our primary aim is to evaluate how patient satisfaction and quality-of-life after conservative oncoplastic surgery, using BREAST-Q (BCT Module), change pre- and post-operatively. The secondary aim is to compare patient-reported outcome after oncoplastic or traditional conservative surgery.

Patients and methods
We enrolled 647 patients who underwent traditional conservative surgery or oncoplastic surgery from January 2020 to December 2022. Only 232 women (35.9%) completed the BREAST-Q questionnaire on a web-based platform, at the preoperative phase and 3 months after treatment.

Results
The average score of “Psychosocial well-being” and “Satisfaction with Breasts” 3 months after surgery showed a statistically significant improvement, while the average score for “Physical well-being: Chest” at 3 months showed a worsening compared to the baseline. “Sexual well-being” did not show statistically significant change. A significant difference between the post-operative outcome of oncoplastic surgery and traditional surgery was observed only for Physical well-being (better for traditional surgery).

Conclusions
The study showed significant improvement in patient-reported outcomes 3 months after the surgery, except for physical discomfort that increases especially after oncoplastic surgery. Furthermore, our data, as well as many others, point to the appropriateness of using OCS where there is an effective indication, while the perspective of patients cannot find significant superiority over TCS in any of the areas analyzed.

Effect of Fault Characteristics on Plastic Zones around Parallelly Spaced Two Underground Caverns and Shear Displacement along the Fault Plane
Authors: Prajapati Sandeep Kumar , Verma A. K. 
Published: June 2023

Abstract
One of the most significant challenges of construction of underground large size structures is to determine the effect of the geological discontinuities. Fault is a natural discontinuity which allows significant displacement of the rock mass along the fault plane and increases the plastic zones around the underground structure. For instance, an underground hydropower plant comprising more than two underground caverns and large distance between the underground cavern incurs the higher cost because of connecting tunnels or transfer of electricity from powerhouse cavern to transformer cavern. However, presence of the fault would result in the increase of the plastic zone and shear displacement along the fault. Thus, with regards to the effect of the fault on the stability of the two parallel caverns, in this paper different numerical models were simulated to study the effect of the fault on plastic zone around the cavern group and pillar between the caverns, and shear displacement along the fault plane under different scenarios such as fault location, fault dip angle, fault friction angle and in-situ stress conditions. The results are produced graphically and discussed. These results offer advance guidelines in construction of the two parallel large size caverns.

Abstract
Pookode, the freshwater lake in the Western Ghats, is a well-known tourist place in southern India, and human interference has turned the otherwise serene environment into a polluted one. This paper discusses the geochemical and textural characteristics of the Pookode lake and by determining the sedimentation rate, an attempt is made to predict the useful life of the lake. The predominance of mud fraction and high organic matter content in sediments favour the accumulation of heavy metals as indicated by the different indices. The sedimentation rate was determined using 137Cs dating method and the maximum lifespan of the lake maintaining its hydrological and ecological functions is estimated as ~700 years.

Published: June 2023

Abstract
This study reports continuous measurements of subsurface soil radon as well as environmental parameters for a period of three years. The survey was carried out along the active fault area in the Indo-Myanmar subduction zone in the north-eastern part which lies in the highest seismic zone of India. The wavelet-based decomposition of the environmental parameters was done using discrete wavelet transformation technique. The denoised environmental parameters by discrete wavelet transformation technique was fed as the inputs to the MLR (multiple linear regression) and MLP (multilayer perceptron) models. Residual radon was calculated and correlated with nearby seismic events. Many events of magnitude greater than or equal to 5 have occurred in the investigation area. It was possible to successfully correlate one event with the anomalous variation in soil radon. The correlated event was the only one with the shallow epicentral depth indicating that the investigated area has undergone a shallow rock fracturing due to the stress generated before the occurrence of the seismic event.
Simulation of nuclear magnetic resonance response based on 3D CT images of sandstone core

Published: June 2023

AbstractIn recent years, nuclear magnetic resonance (NMR) logging has become increasingly prevalent in the characterization of rock properties such as porosity, permeability, saturation, and pore size distribution. However, interpreting such properties accurately from NMR logging data is challenging for some reservoirs. In particular, the impact of salinity, viscosity, and saturation on NMR measurements is not always clear, which can lead to inaccuracies in the resulting data interpretation. Properly accounting for these factors is essential in order to obtain accurate and reliable measurements for effective characterization of subsurface formations. This study utilized a random walk technique to simulate the NMR response of homogeneous sandstones using 3D CT images and conducted a sensitivity analysis under various salinity, crude oil viscosity, and water saturation conditions. The results indicate that the T2 relaxation time slightly shifts toward the short relaxation direction as the salinity of the formation water increases. In addition, longer echo intervals result in a more significant forward shift in the T2 value than shorter intervals. Whereas, for crude oil, the T2 relaxation time becomes shorter as its viscosity increases. Furthermore, the effect of echo interval on the forward T2 shift is less pronounced for crude oil than it is for formation water. Under water wet conditions, the T2 spectrum of crude oil exhibits a peak at the volume relaxation position. As the water saturation decreases, the left two peaks in the T2 spectrum shift toward shorter relaxation times. Under oil wet conditions, the T2 spectrum exhibits a complex three-peak structure. The method provides a physical basis for interpreting NMR macroscopic responses, and the simulated NMR responses can help identify fluids in reservoirs.

AbstractObjectiveWith a rise in remote clinical practice related to the COVID-19 pandemic, a novel remote psychotherapy curriculum was presented to psychiatry residents and fellows to address the urgent need to teach trainees how to adapt traditional psychotherapy skills to telepsychiatry settings.MethodsTrainees completed a survey before and after receiving the curriculum to assess remote psychotherapy skills and areas for growth.ResultsEighteen trainees (24% fellows, 77% residents) completed the pre-curriculum survey, and 28 trainees (26% fellows, 74% residents) completed the post-curriculum survey. Thirty-five percent of pre-curriculum participants indicated no experience with remote psychotherapy. Technology (24%) and patient engagement (29%) were identified as the greatest challenges in providing teletherapy pre-curriculum. Content related to patient care (69%) and technology (31%) was of most interest to pre-curriculum participants and identified as most helpful post-curriculum (53% and 26%, respectively). After receiving the curriculum, most trainees planned to make internal, provider-related changes to their remote teletherapy practice.ConclusionsThe remote psychotherapy curriculum was well received by psychiatry trainees who had limited experience with remote clinical practice prior to the pandemic.
Turbine Inlet Valve’s Self-Excited Vibrations Risk the Safe Operation of Hydropower Plants
Authors: Awad Hesham , Parrondo Jorge 
Published: June 2023

Abstract
Purpose
The main function of the turbine inlet valve (TIV) in a hydroelectric power plant is to prevent flow of water to the turbine whenever the turbine is not operating. Usually, the valve responsible for this operation is spherical with annular seals to perform the sealing function. Occasionally, when the valve is set into a closed orientation, the annular seal may not execute its sealing function properly though develop periodic oscillations accompanied by periodic leakage flows. These seal vibrations cause pressure fluctuations in the penstock pipeline, which risks the plant’s reliable and safe operation. Therefore, the primary goal of this research is to present a simplified theoretical model, able to clarify the excitation mechanism of the periodic seal vibration and simulate the plant’s transient behavior. Afterwards, develop some recommendations to enhance the stable operation of the (TIV).

Methods
The system governing equations comprises the water hammer equations to model the water flow through the various pipelines, the vibrating seal equation of motion, and the system boundary conditions.

Results
The dynamic instability of the (TIV) vibrations is more likely to arise at higher input reservoir energy levels and at the first harmonic of the seal oscillation. In addition, modifying the (TIV) by increasing pilot pipeline head losses and reducing its diameter can eliminate the (TIV) vibrations and warrant the plant’s safe operation.

Conclusion
Results revealed that fluid compressibility and acoustic transmission have a decisive effect on the fluid-dynamic forces acting on the seal and the (TIV) stability. In addition, the origin of the (TIV) vibrations is the valve leakage flow through the service seal.
Rescuing the Golgi from heat damages by ATG8: restoration rather than clean-up
Authors: Luo Anni , Liu Jian-Xiang 
Published: June 2023

AbstractHigh temperature stress poses significant adverse effects on crop yield and quality. Yet the molecular mechanisms underlying heat stress tolerance in plants/crops, especially regarding the organellar remodeling and homeostasis, are largely unknown. In a recent study, Zhou et al. reported that autophagy-related 8 (ATG8), a famous regulator involved in autophagy, plays a new role in Golgi restoration upon heat stress. Golgi apparatus is vacuolated following short-term acute heat stress, and ATG8 is translocated to the dilated Golgi membrane and interacts with CLATHRIN LIGHT CHAIN 2 (CLC2) to facilitate Golgi restoration, which is dependent on the ATG conjugation system, but not of the upstream autophagic initiators. These exciting findings broaden the fundamental role of ATG8, and elucidate the organelle-level restoration mechanism of Golgi upon heat stress in plants.
The Non-Fungible Value of Local Associations and its Invisibility to Law
Authors: Cahill Maria 
Published: June 2023

AbstractThis article centers on the idea that there is a non-fungible value inherent in local associations. It uses the work of Paul Kahn to animate what that value might be and to consider why law might not have a clear sightline to it. In Democracy in Our America, Kahn, leaning on Tocqueville’s earlier work, reflects on the nature of volunteerism in local self-government and the value of local associations. Drawing on his experience-based account of the practice of local self-government, I suggest that local associations have a non-fungible value which comes in three dimensions: The dimension of care, the dimension of character, and the dimension of forum vibrancy. In The Cultural Study of Law, meanwhile, Kahn considers what the practice of the rule of law looks like and suggests that law is blind to other possible ways of framing and analyzing events. Building on this perspective, I reflect on how the practice of the rule of law ends up being blind to the value that is intrinsic to the local associations that vivify local communities. Through this lens, we can also understand more fully than has been possible to date why legal codifications of the principle of subsidiarity fail to result in a genuine preference for proximity.
