Published: May 2023

Abstract
Liquid metals (LMs) exhibit several key characteristics justifying their utilization as coolants and breeders for nuclear fusion reactors and advanced fission reactors. In fusion reactors, the LMs confront an exorbitantly high flow retarding force, due to the magneto-hydro-dynamics (MHD) effect, imposing significant demands on the pumping power and designs of ancillary coolant systems. Corrosion of structural materials leading to activated corrosion products and coolant chemistry control are some of the vital issues common to both fusion and fission reactors employing liquid lead (Pb) and its alloys. To address these concerns, different technological solutions such as flow channel inserts (FCIs) and high temperature compatible corrosion resistant coatings are being investigated to provide a chemical and/or electrical isolation between the LM and structural material for advanced reactors. In this study, three different prototype geometries (circular, square, and 90 deg bend) of steel-insulator-steel sandwich FCIs are fabricated for fusion reactor applications and an extensive characterization of the electrical insulation is performed over an operating temperature range of 100 °C–600 °C. Welding trials and pneumatic pressure tests up to 10 kg/cm2 (g) are performed on the assemblies to validate the electrical and mechanical integrity over typical fusion reactor operational regime. This paper presents detailed fabrication aspects along with quantitative estimations of insulation filling density, electrical insulation performance and, for the first time, a detailed systematic study of insulation degradation resulting from the combined effects of tungsten inert gas (TIG) welding, exposure to pressure and machining operations on these FCIs. The paper also provides critical details derived from the metallurgical examinations and visual observations from the destructive tests executed on the prototypes. Further, from an implementation perspective toward Lead-cooled Fast Reactors (LFRs), a preliminary feasibility assessment of the α-Al2O3/AlPO4 coating is performed through thin film deposition trials on planar and non-planar substrates followed by mechanical characterizations, such as coating thickness, surface roughness, adhesion strength and microhardness. Metallurgical analyses are presented and discussed to assess Pb ingress after 700 h of continuous exposure to molten Pb alloy at 300 °C–400 °C.

Abstract
In the actual operation of pumps, regulating the rotating speed of the pump based on the affinity law through variable speed drives is deemed as a prudent and convenient approach to mitigate energy loss. However, the multistage side channel pump is composed of one centrifugal impeller at the first stage and one or more side channel structures, the applicability of affinity law to this composite structure has not been confirmed. Three schemes with different suction angles of single-stage and one multistage side channel pump were investigated under different rotating speeds through numerical and experimental analysis. The findings elucidated that the single-stage side channel pumps exhibit a proportionate relationship to the affinity law, regardless of how the geometry varies. The numerical work was validated by the comparison between the simulated result and the tested result of the multistage side channel pump under two rotating speeds. Noticeably, the entire performance of the multistage side channel pump conforms to the affinity law, which has the same phenomenon as the single-stage side channel pump. The entropy production causing dissipation of turbulence flows in each stage exhibits a similar tendency as the overall head. As a result, the vortex distribution in average time and transient moment are almost analogous in the impeller of each stage under corresponding flow points. This briefly explains composite structures could be considered as pumps in series regardless of their composition. The outcome of this research could offer a theoretical basis for energy-saving methods of side channel pumps.
Solving Nonlinear Elliptic PDEs in 2D and 3D Using Polyharmonic Splines and Low-Degree of Polynomials
Authors: Rubasinghe Kalani , Yao Guangming , Li Wen , Tsogtgerel Gantumur 
Published: May 2023

In this paper, the improved localized method of approximated particular solutions (ILMAPS) using polyharmonic splines (PHS) together with a low-degree of polynomial basis is used to approximate solutions of various nonlinear elliptic Partial Differential Equations (PDEs). The method is completely meshfree, and it uses a radial basis function (RBF) that has no shape parameters. The discretization process is done through a simple collocation technique on a set of points in the local domain of influence. Resulted system of nonlinear algebraic equations is solved by the Picard method.The performance of the proposed method is tested on various nonlinear elliptical problems, including the Poisson-type problems in 2D and 3D with constant or variable coefficients on rectangular or irregular domains and the Poisson–Boltzmann equation with Dirichlet boundary conditions or mixed boundary conditions. The effect of domain shapes in 2D and 3D, types of boundary conditions, and degrees of PHS, and order of polynomial basis are examined. The performance of the method is compared with other bases such as multiquadrics (MQ) basis functions, and with results reported in the literature (method of particular solutions using polynomials). The numerical experiments suggest that ILMAPS with polyharmonic splines yields considerably superior accuracy than other RBFs as well as other approaches reported in the literature for solving nonlinear elliptic PDEs.
Once Again about the Apocryphal Prayer “7 Angels and 7 Archangels Walked...” in the Vernacular Slavonic Written Tradition
Authors: Todorova Ekaterina 
Published: May 2023

Abstract
The article examines an unpublished apocryphal prayer against “nezhit” and traces the tradition of its origin in South Slavic medieval literature. The prayer begins “7 angels and 7 archangels walked, 7 candles carried, 7 knives sharpened …”. The “nezhit” disease is, generally speaking, a severe headache, which, according to Christian beliefs, develops into an obscure disease associated with the possession of demonic powers. In the apocryphal prayer, there is a repeated semantic dominance of the number 7, aimed at sacralization and an additional guarantee of success in the battle with diseases, since the number 7 is sacred both in pagan beliefs and in Christianity.
Chrysostom and Generation Z: Resilience, Identiy, and Social Justice
Authors: Maddox Tanita Tualla 
Published: May 2023

Abstract
Generation Z (Gen Z) comprises current adolescent culture, bringing with them a generational worldview lens for topics such as: suffering, success, identify formation, and social justice. Gen Z values safety, has a heart for the outcasted, and is forming identity around successes and accomplishments. This article seeks to ground Gen Z with a piece of historical Christian faith and teaching, applying the fourth-century teachings of John Chrysostom to today’s Gen Z. Much like Chrysostom’s audience, Gen Z views suffering and hardship as punitive and to be avoided. Chrysostom’s teaching provides a fuller understanding of suffering, equipping his audience, and today’s Gen Z, with a mode for building resilience through thanksgiving. Chrysostom taught on the importance of charity, which allows Gen Z to engage their generational values for tolerance and acceptance in the Kingdom of God.
A Formal Foundation for Comparative Study of the Late Persianate
Authors: Thompson Levi 
Published: May 2023

Abstract
This article addresses poetic form as a foundation bridging the literary contexts of Arabic and Persian that exists beyond the bounds of Euro-American influence. We find the originally Arabic science of ʿarūḍ, prosody, used in these two contexts to retool premodern poetic form for the modern era. Questions of form encourage us to think about how modernist poets writing in Persian and Arabic approach their poetry as a craft that emerges not out of engagements with Western literature but rather from a shared poetic past. By tracing formal links across Arabic and Persian, this article argues that paying attention to the premodern tradition of prosodic science they share helps us both to understand the early development of modernist poetry in each language and to avoid explanations informed mostly by literary critical frameworks used to study Western literatures.

Published: May 2023

Although transcatheter aortic valve replacement (TAVR) is safe and effective, mortality and bleeding events post procedure are important. The present study investigated the changes in hematologic parameters to evaluate whether they predict mortality or major bleeding. We enrolled 248 consecutive patients (44.8% male; mean age 79.0 ± 6.4 years) undergoing TAVR. In addition to demographic and clinical examination, blood parameters were recorded before TAVR, at discharge, 1 month and 1 year. Hemoglobin levels before TAVR 12.1 ± 1.8 g/dL, 10.8 ± 1.7 g/dL at discharge, 11.7 ± 1.7 g/dL at first month, 11.8 ± 1.4 g/dL at first year (Hemoglobin values compared with pre-TAVR, P < .001, P = .019, P = .047, respectively). Mean platelet volume (MPV) before TAVR 8.72 ± 1.71 fL, 8.16 ± 1.46 fL at discharge, 8.09 ± 1.44 fL at first month, 7.94 ± 1.18 fL at first year (MPV values compared with pre-TAVR, P < .001, P < .001, P < .001, respectively). Other hematologic parameters were also evaluated. Hemoglobin, platelet count, MPV, and red cell distribution width before the procedure, at discharge, and at the first year did not predict mortality and major bleeding in receiver operating characteristic analysis. After multivariate Cox regression analysis, hematologic parameters were not independent predictors of in-hospital mortality, major bleeding, and death at 1 year after TAVR.

Published: May 2023

Introduction: Aminoglycoside antibiotics such as gentamicin are bactericidal and effective against gram negative organisms and act synergistically against gram positive organisms, including S taphylococcus aureus. However, they have serious adverse effects such as nephrotoxicity and ototoxicity. Gentamicin ototoxicity may occur after a single dose and results in decreased vestibular function, which is frequently debilitating and often permanent. Objective: To emphasize the risk of gentamicin ototoxicity and suggest alternative antibiotics in penicillin-allergic patients undergoing surgery. Case Summary: We present a case of a woman with preexisting Meniere’s Disease who received gentamicin 400 mg perioperatively for a sigmoidectomy due to a penicillin allergy listed in the patient’s medical record. The patient developed severe ototoxicity preventing her from working or driving. Physical examination was remarkable for a broad-based gait requiring assistance to walk and bilateral corrective saccades. Vestibular testing revealed high-grade bilateral vestibular loss associated with all semicircular canals, a considerable decline compared to her function 3 years prior. Discussion: Gentamicin is indicated for surgical prophylaxis when a patient has a true allergy to penicillins and cannot receive cephalosporins, though alternatives exist. True allergies include IgE-mediated illness (anaphylaxis, bronchospasm, or urticaria 30-60 minutes after administration) or exfoliative reactions (Stevens-Johnson Syndrome or Toxic Epidermal Necrolysis). The authors encourage more prudent use of gentamicin, especially in patients susceptible for debilitating otologic insults, and offer recommendations for alternative agents prior to using gentamicin.

Objectives: Childhood trauma is common and associated with mental ill health. While high rates of trauma are observed across individual disorders, there is evidence that trauma is associated with an admixture of affective, anxiety and psychotic symptoms in adults. Given that early onset of mental disorder and trauma exposure herald poor outcomes, it is important to examine trauma prevalence rates in youth mental health services and to determine whether this trauma-related clustering is present in help-seeking young people. Methods: We used data from the Transitions Study, a longitudinal investigation of young people attending headspace youth mental health services in Australia between January 2011 and August 2012. Participants were 775 young people aged 12–25. Childhood trauma was assessed using the Childhood Trauma Questionnaire. Multinomial regression was used to assess whether reported childhood trauma was more strongly associated with the co-occurrence of depression, anxiety, mania and psychosis symptoms than with any one in isolation. Results: Approximately 84% of participants reported some form of abuse (emotional: 68%; physical: 32%; sexual: 22%) or neglect (emotional: 65%; physical: 46%). Exposure to multiple trauma types was common. Childhood trauma was significantly associated with each symptom domain. More severe childhood trauma was more strongly associated with the co-occurrence of symptoms than with any one symptom domain in isolation, such that more severely trauma-exposed young people were more likely to experience increased symptom clustering. Conclusions: Childhood trauma is pervasive in youth mental health services and associated with a symptom profile that cuts across traditional diagnostic boundaries.
The complex impact of family caregiver kinship type on the rehabilitation of patients with mental disorders in rural communities of China
Authors: Ji Wu , Xin Sui , Xijin Wang , Xue Qiu , Xu He 
Published: May 2023

Background: In 2009, the Chinese government incorporated severe mental disorders into the central subsidized local health funding project for the effective management, treatment, and reintegration of patients with severe mental disorders from hospitals into the community (Project 686). The conditions that were classified as ‘severe’ by this project included: schizophrenia, schizoaffective disorders, paranoid disorders, bipolar disorders, mental disorders caused by epilepsy, and mental retardation accompanying mental disorders. Patients in rural communities received better care after project implementation, of which 62.91% were farmers. Objective: This paper attempts to investigate the complex impact of Project 686 on the levels of rehabilitation of patients by their families. Methods: The last follow-up visit of the community psychiatrists in city H in 2020 was used as the time point. Finally, 174 samples were used in the analysis model. The type of kinship between family caregivers and patients with mental disorders was operationalized according to the information provided under the ‘primary caregiver’ item within the basic information section of the follow-up form. The software Stata15 was used to perform descriptive statistics, baseline regression model analysis, and a robustness test on the types of kinship identified and patients’ recovery. Results: The types of kinship, current symptoms, and medication use all affected patients’ recovery, were found to have regression coefficients of −0.148, −1.756, and 0.902, respectively. Parents of patients with mental disorders remain in the caregiver category with the largest proportion. Community acceptance of patients is high; current symptoms, medication use, and types of caregiver-patient relationships influence patients’ recovery levels. Conclusions and discussion: Project 686 has solved some of the rehabilitation and living difficulties of patients with mental disorders in rural communities. The types of kinship between family caregivers and patients with mental disorders in rural communities affect patients’ rehabilitation levels. Patients’ current symptoms and medication use can effectively moderate the impact of kinship type on patients’ recovery in terms of complete self-knowledge, productive work, and life and good social relationships. It is necessary for mental illness prevention-treatment organizations to establish supplemental, replacement, and substitution mechanisms for the life and rehabilitation of patients with mental disorders in rural communities. Furthermore, the sense of reward and concern for family caregivers should be actively enhanced, and greater scientific use of the rehabilitation function of the ‘family care + village doctor management’ model should be made.

In the presented study, aluminum metal matrix nanocomposites reinforced with SiC and B4C, with different reinforcement ratios (0–4 wt%), have been prepared using the powder metallurgy method. The main objective of this study is to investigate the effect of different reinforcements and reinforcement amounts on the machinability of metal matrix nanocomposites using different machining processes (WEDM and CNC milling). The surface morphologies of the samples were investigated before and after machining using scanning electron microscopy and chemical analysis of the samples was obtained using EDX and X-ray diffraction. The surface hardness, roughness, and metal removal rate (MRR) before and after machining were examined to investigate the effect of the machining process on the surfaces of the samples. According to the results of the study, the hardness value of the nanocomposite containing 4% B4C by weight (195.6 HB) increased by approximately 90% compared to the hardness value of the pure Al2024 alloy (101.6 HB). After both machining processes, the hardness values of all nanocomposites decreased. In addition, the tensile strength values of the nanocomposites containing 2% B4C and SiC by weight are 392.8 MPa and 377.7 MPa, respectively, while the tensile strength value of the pure Al2024 alloy is 201.7 MPa. After both machining processes, the hardness values of all nanocomposite samples decreased. While the MRR values decreased with the increase in the reinforcement amount of the nanocomposites after machining, the SR values decreased.
Editors in Chief of Public Health Reports, 1878-2022: Men and Women Who Shaped the Discussion of Public Health Practice From 1918 Influenza to COVID-19
Authors: Harada Noelle M. , Kuzmichev Andrey , Dean Hazel D. 
Published: May 2023

Objectives: Public Health Reports ( PHR), the official journal of the Office of the US Surgeon General and US Public Health Service, is the oldest public health journal in the United States. Considering its heritage through the eyes of its past editors in chief (EICs), many of whom have been influential public health figures, can provide a fresh point of view on US public health history, of which the journal has been an integral part. Here, we reconstruct the timeline of past PHR EICs and identify women among them. Methods: We reconstructed the PHR EIC timeline by reviewing the journal’s previous mastheads and its articles describing leadership transitions. For each EIC, we identified dates in office, concurrent job titles, key contributions, and other important developments. Results: PHR had 25 EIC transitions in 109 years of its history, during which a single individual in charge of the journal could be identified. Only 5 identifiable EICs were women, who served as EIC for approximately one-quarter of the journal’s traceable history (28 of 109 years). PHR’s longest-serving EIC was a woman named Marian P. Tebben (1974-1994). Conclusions: PHR history revealed frequent EIC transitions and a low representation of women among its EICs. Mapping the timeline of past EICs of a historic public health journal can yield valuable insights into the workings of US public health, especially in the area of building a research evidence base.

Published: May 2023

Background: Study tours are known to have an important role in enriching the knowledge of students in all fields. Our study aimed to evaluate the experience of a postgraduate and faculty study tour in the field of mental health. Methods: We obtained both quantitative and descriptive feedback from 31 participants who had taken part in the annual study tour conducted in the years 2014–2018 using a specially designed feedback pro forma. Results: All the participants reported overall satisfaction with the tour. Learning was enhanced, and most found the tour relevant to their current field of study. They particularly enjoyed the experience of traveling in a peer group without faculty supervision and learning to make decisions as a group. Their chief concerns were about the continuous travel and the limited time allotted to each center. Conclusions: A well-planned study tour during training helps trainees in the mental health field improve their knowledge, hone practical skills, and learn life lessons; it promotes bonding with peers and fosters self-directed learning and independence. The limitations were the inability to have direct face-to-face interviews with most participants and the study tour centers being limited to a small geographical area.

Published: May 2023

Objective This retrospective study compared two minimally invasive surgical methods for fifth metacarpal neck fractures in adolescents: percutaneous Kirschner wire (K-wire) fixation and elastic stable intramedullary nailing (ESIN). Methods This study involved 42 adolescents aged 11 to 16 years with fifth metacarpal neck fractures treated by either K-wire fixation (n = 20) or ESIN (n = 22). The palmar tilt angle and shortening were compared on radiographs preoperatively and 6 months postoperatively. Total active range of motion (TAM), the visual analogue scale score for pain, and the Disabilities of the Arm, Shoulder and Hand score for upper limb function were recorded at 5 weeks, 3 months, and 6 months postoperatively. Results The mean TAM was significantly greater in the ESIN than K-wire group at all postoperative time points. The mean external fixation time was 2 weeks longer in the K-wire than ESIN group. One patient in the K-wire group developed infection. There was no statistically significant difference between the two groups in other postoperative outcomes. Conclusions ESIN fixation has the advantages of greater stability, better activity, a shorter external fixation time, and a lower infection rate than K-wire fixation in the treatment of fifth metacarpal neck fractures in adolescents.
