Dystrophic calciphylaxis in panniculitis: features of the clinical picture and diagnosis
Authors: Egorova O. N. , Datsina A. V. , Severinova M. V. 
Published: August 2023

The clinical presentation of lobular panniculitis (PN) associated with calciphylaxis (CP, calcification) can vary widely and may be associated with joint and internal organs involvement, making the diagnosis of the disease difficult.Objective: to evaluate the frequency and significance of CP in patients with PN using long-term prospective follow-up.Material and methods. From 2018 to 2023, at the V.A. Nasonova Research Institute of Rheumatology 217 patients with referral diagnosis "erythema nodosum" or "panniculitis" were examined. In 19.3% of cases (9 men and 33 women aged 37 to 72 years) CP was confirmed with an average disease duration of 56.3±11.2 months. Clinical examination of patients was performed according to the standards recommended by the Russian Association of Rheumatologists. International criteria were used to confirm the diagnosis of systemic lupus erythematosus (SLE), idiopathic inflammatory myopathies (IIM), systemic sclerosis (SS), and lipodermatosclerosis (LDS). In 12 patients with indurations, pathological examination of biopsy specimens of skin and subcutaneous fatty tissue from the area of induration was performed, which allowed confirming the diagnosis of idiopathic lobular PN (ILPN) in 3 cases. Four grades of calcification were distinguished according to the size and depth of the calcifications. In addition, considering the type of radiological changes and clinical manifestations, four subtypes of CP were identified: mousse-like, stone-like, mesh-like and lamellar-like.Results and discussion. In the study group, the ratio of women to men was 3.6:1, and the mean age was 43.8±7.6 years. On clinical examination we determined, in 60% of cases CP predominantly stone-like subtype (71.4%) of first grade (47.6%), which was significantly more frequently located on the upper and/or lower extremities and/or trunk (57.1%; p=0.05). Using clinical, laboratory and instrumental data, we confirmed the development of CP in ILPN (n=3), SLE (n=3), LDS (n=21), IIM (n=5), SS (n=1), and idiopathic CP (n=9) with a mean disease duration of 8.7±2.4 years.An increase in ESR and CRP levels occurred in different diseases, while urinary syndrome was associated with SLE (66.6%) and an increase in creatinine phosphokinase with IIM. Decreased calcium and 25-hydroxyvitamin D levels and increased phosphorus and parathyroid hormone levels were found in many patients studied.Conclusion. In the absence of clear diagnostic criteria for CP in patients with PN, early diagnosis is critical for the development of an effective multidisciplinary treatment plan.

In patients with systemic sclerosis (SSc), interstitial lung disease (ILD) is a factor in the decline of functional capacity up to disability and is also the leading cause of death. Therefore, one of the most important tasks in the treatment of this group of patients is not only to detect involvement of respiratory system, but also to predict the likelihood of its development.Objective: to study the possibility of predicting the development of ILD and advanced ILD in patients with SSc.Material and methods. The study included 79 patients with SSc (mean age 64.4±11.5 years; 94.9% women) from the Registry of myositis, SSc and Mixed Connective Tissue Diseases (РЕМИССиС) who underwent high-resolution computed tomography (HRCT) of the lungs. Classification trees (CTr) were constructed to predict the development of widespread ILD using the CHAID algorithm (exhaustive). All patients were tested for antibodies against Scl-70 (anti-Scl-70), CENP-B (anti-CENP-B), and PmScl (anti-PmScl).Results and discussion. ILD signs according to HRCT were detected in 53 patients. Fibrotic (34.2%) and cellular (15.2%) types of nonspecific interstitial pneumonia were the most common, and common interstitial pneumonia was less frequent (11.4%).The presence of ILD and advanced ILD (involvement of more than 20% of the lung parenchyma) were significantly associated with the detection of any autoantibodies, except anti-centromere antibodies, an increase in pulmonary artery systolic pressure, a decrease in forced vital capacity, diffusing capacity of the lungs, blood oxygen saturation at rest, and all parameters of six-minute walk test (6MWT), and complaints of shortness of breath. In addition, the presence of extensive ILD was also significantly associated with diffuse SSc and with SSc without skin manifestations.In establishing the CTr, it was found that the development of widespread ILD was unlikely in individuals who were able to walk more than 440 m in 6MWT and had neither anti-Scl-70 nor anti-PmScl.Significant associations were also found between the radiological pattern of ILD and the types of disease-specific antibodies.Conclusion. The 6MWT data in conjunction with the results of testing for SSc-specific autoantibodies provide a very accurate prediction of the presence and extent of ILD. It is advisable to include these indicators in the algorithm for screening and monitoring patients with SSc.

Published: August 2023

Objective: to study the course of COVID -19 and post-covid syndrome (PCS) in patients with rheumatoid arthritis (RA).Material and methods. The study included 32 adult patients with a confirmed diagnosis of RA, who met ACR/EULAR criteria. All patients had COVID-19. Material for analysis was obtained by means of a questionnaire developed at the V.A. Nasonova Research Institute of Rheumatology, which patients completed during their interview with the researcher.Results and discussion. The study group consisted mainly of women (n=29, 90%). The mean age of the patients was 50.75±16.48 years. Among the clinical manifestations of COVID-19, weakness/fatigue (90.6%; p<0.0001), fever (71.9%; p=0.0005) and anosmia (62.5%; p=0.045) were significantly more common. Almost half of the patients had dysgeusia (59.4%), increased arthralgia (53.1%), dyspnea on exertion (50%), and cough (46.9%). A significant positive association was found between increased arthralgia during COVID-19 and RA activity (r=0.72; p<0.05). Hospitalisation was required in 37.5% of patients with COVID-19. In 12.5% of cases, COVID-19 progressed with complications. Patients with higher RA activity were more likely to have an increase in arthralgia as a symptom of infection. PCS was registered in 47.8% of patients who underwent COVID-19. Retrospective evaluation of patients with PCS revealed a higher rate of hospitalisation in infectious disease departments and a more severe course of COVID-19. Subsequently, repeated cases of COVID-19 were more common in this group.Conclusion. Risk assessment of PCS development is necessary to appropriately distribute the burden on the health care system and to develop a strategy for prevention, timely diagnosis, and treatment of this syndrome in patients with rheumatic diseases. To achieve this goal, new studies in a larger cohort of patients with RA and rheumatic diseases in general are needed.
Beyond dynasties and binary alternations: a diachronic corpus study of four-way variability in Chinese theme-recipient constructions
Authors: Li Yi , Szmrecsanyi Benedikt , Zhang Weiwei 
Published: August 2023

Abstract
Despite the vast body of literature on the historical development of the theme-recipient alternation (also known as the “dative” alternation) in Chinese, most studies that have been conducted so far are limited to philological recounts of the binary choice between the prepositional dative and the ditransitive dative across dynasties, which usually spanned centuries. Against this backdrop, we conduct a state-of-the-art variationist analysis of the four variants, utilizing a large and richly annotated diachronic dataset based on a corpus of Chinese texts (1300s–1900s). Using conditional inference trees and conditional random forest analysis, we demonstrate that end-weight effects are the most stable linguistic constraint on variation, while definiteness and animacy of the theme constituent tend to be more fluid. Supplementary distinctive collexeme analysis reveals a strong collostructional interplay between verbs and the variants, including changes involving the prototypical verb of GIVING 给gĕi.
Climate-Related Vulnerability Assessment Toward Disaster Risk Reduction: Insight from Pakistan
Authors: Abbas Hafiz Waqar , Guo Xuesong 
Published: August 2023

AbstractGlobally, climate-related disasters (CRDs) have become a common phenomenon in the last few decades, increasing vulnerability and causing disaster mortality. To manage disaster risk, the global Sendai Framework for disaster risk reduction (SFDRR) provides a solid action plan for disaster risk reduction (DRR) considering all the dimensions of vulnerability. However, countries are still less receptive at the local level to adopting the SFDRR. Also, the global research community did not explore vulnerability features based on the Sendai Framework nor integrated such features with the four priorities of SFDRR. Based on the case of Pakistan, this study seeks to bridge the gap through three objectives. The first objective of the study is to identify the vulnerability features cited in the SFDRR. In addition, the research aims to develop a new vulnerability model by integrating SFDRR’s four priorities. As a second objective, it is intended to develop a decision support framework for ranking and evaluating each of the SFDRR priority action areas under local conditions. A third objective is to assess the impact of climate-induced environmental, socioeconomic and political vulnerabilities on climate-driven mortality. To meet these three different objectives, the authors have adopted a multi-method approach by using multi-criteria decision analysis (MCDA) and binary logistic regression method (BLRM). Based on the assessment, the authors suggested some policy implications.

Published: August 2023

Abstract
In this study, Inconel 625 alloy was initially aluminide coated by halide-activated pack cementation at 700 °C for 4 h using fine (40–45 µm) globular and coarse (10–75 µm) ligament aluminum particles. Microstructural features and hardness variation of the coatings along with their oxidation behavior at 1000 °C during 50 h were investigated to reveal the effect of pack characteristics on the properties. Investigations revealed that (i) a homogeneous and continuous coating layer was formed on the surface without internal oxidation, (ii) a thicker coating (∼60 µm) was formed due to the pack consisting of coarse particles, (iii) a higher hardness value (1369 HV0.5) was measured for the coated alloy using fine particles in the pack, and (iv) the coating with coarse powder exhibited higher oxidation resistance during the first 50 h of oxidation test period. Secondly, superalloy was coated at different temperatures (700 and 1000 °C) and times (2 and 4 h) using coarse particles. In this stage, the findings showed that by increasing process temperature and time, the accumulation of aluminum on the superalloy surface increased and the oxidation tendency remained at a lower level in coatings containing thicker layers.
The WG Fractography Online Database – stage of development and planning
Authors: Bettge D. , Schmies L. 
Published: August 2023

Abstract
Since 2013, the AG Fraktographie (Working Group (WG) Fractography) in the DVM/DGM Joint Committee “Elektronenmikroskopie in der Materialforschung” (Electron Microscopy in Materials Research) maintains a fractographic online database (“FractoDB”, [1, 2]) available to interested professionals. When it comes to identifying failure mechanisms and causes of damage, the analysis and evaluation of fracture surfaces and their characteristics constitute important aspects of the failure analysis. Cracks and fractures in real components can only be assessed if well-documented comparative fractures from laboratory tests are available – be it in samples or in comparison components. The WG Fractography therefore gathers image material, systematically carries out laboratory and round robin tests, and analyzes fractures from failure cases. From thus obtained data, datasets are compiled and made available via the database. Currently, a browsable inventory of more than 400 datasets with a total of more than 4500 images is available. It is organized in line with guideline VDI 3822 [3]. Other activities of the WG Fractography represented in the FractoDB include, among others, the development of a fractographic set of symbols [4, 5] and the analysis of fracture characteristics using machine learning [6]. This contribution reports on latest results and plans.
A brief guide to conducting failure analysis on ceramic components
Authors: Harrer W. , Morrell R. , Danzer R. 
Published: August 2023

Abstract
Failure investigations are mainly conducted for the purpose of clarifying the root causes for component failure. Possible aims of these investigations are to analyze the unexpected failure of a component during operation, to improve the material and to assess the quality of a product. Usually, ceramics can be used in similar ways as other structural materials. There are particularities, however, which need to be considered in failure analysis of ceramic components.
This paper will therefore give a brief overview of the types of damage which may occur in ceramic materials, with the focus being on failures occurring at room temperature and medium temperatures (e. g., brittle fracture, contact stresses or stresses caused by rapid temperature changes).

Published: August 2023

Abstract
Cold spray is considered as an emerging technique for preparing wear-resistant metal matrix composite coatings on the surface of various kinds of metallic materials. In this work, a viable strategy of “cold spraying + hot rolling post-treatment” was successfully applied to prepare wear-resistant B4C/6061 Al composite coating on commercially available 6061 Al plates. The results revealed that hot rolling post-treatment results in uniform distribution of B4C particles in the alloy matrix, good inter-splat bonding, and sufficient plasticity in the splats through effective healing of the defects and splat boundaries in the as-sprayed deposit. As a result, the coating/substrate bonding strength in the hot rolled sample increased two-fold when compared with that of the as-sprayed sample. Moreover, hot rolling process resulted in much improved tribological properties of the coating with the wear rate ∼40% of that of the substrate. The obtained results indicated that the idea of combining cold spraying and hot rolling treatment is quite effective for improving the tribological properties of Al alloy plates. Further, this approach seems equally good for repairing/remanufacturing of unserviceable 6061 Al alloy components.

Published: August 2023

Abstract
Single phased white light emitting phosphors are more ideal for fabricating white LEDs due to higher stability and color reproducibility. Herein, we report a new white light emitting phosphor, SrCeO3: xSm3+ (x = 1 wt%, 2 wt%, 3 wt%) from a blue light emitting phosphor, SrCeO3 using an efficient, low energy consuming fuel excess gel combustion technique. From the XRD crystallographic investigation, all the synthesised samples have orthorhombic structure with space group Pnma. A broad absorption band in the UV–visible spectra around 350 nm occurs due to the efficient energy transfer from Ce4+ to Sm3+ ion. PL spectra analysis at UV excitations 280 nm and 406 nm, consist of 4f-Sm3+ transitions 4G5/2-6H5/2, 4G5/2-6H7/2, 4G5/2-6H9/2 and charge transfer band from O2− to Ce4+. The energy transfer between activator ions occurs through dipole–dipole interaction, owing to concentration quenching after 2 wt% Sm3+ and the optimised dopant concentration was 2 wt%. SrCe0.98Sm0.02O3 showed mixed blue-yellow-orange-red emission, owing near white light under both excitations. PL data were utilised to find the color parameters and found high color rendering index (CRI ∼ 84) for optimised sample at 406 nm excitation. SEM analysis reveals that the optimised sample exhibit dense ensembled morphology with well-defined grain boundaries and uniformity with average grain size ∼1.24 μm. Further, the elemental composition was confirmed using EDS analysis. From the digital photographs of samples, it is foreseen that, SrCe0.98Sm0.02O3 pumped using near UV LED chip can be used for commercial white light generation.

Authors: Şimşek Veli 
Published: August 2023

Abstract
Mesoporous materials (MMs) in the Santa Barbara Amorphous (SBA) family can be used as catalysts or support materials (SMs) for catalysts because they have controllable pore structure, thermal and chemical stability, and their surface properties can be modified easily depending on the desired reaction type. Surfactant (Pluronic p123; it is a symmetric triblock copolymer comprising poly and its chemical formula; HO(CH2CH2O)20(CH2CH(CH3)O)70(CH2CH2O)20H), a silica source (such as Tetraethyl orthosilicate: TEOS; SiC8H20O4), and a solvent are used in the synthesis of the SBA family (SBA-15). The SBA-15 was given with the hydrothermal method (HM) a catalyst feature by loading the active substance at a rate of 10, 25 % (cadmium/silica) by mass. Esterification reactions (ERs) were carried out with Cd-SBA-15 (Cd/Si: 10–25 %) catalyst at a feed rate of 1/2 (methanol/acetic acid), in the presence of 0.4 g catalyst, at a reaction temperature of 373 K and for 6–48 h. After 48 h, the catalytic activity (CA) values were obtained as 65 and 68 %, respectively. The re-usability of the catalysts was repeated two times under the same experimental conditions. It was observed that the catalysts maintained their catalytic activity of 73.35 and 68.72 % (3 × 48 h). In addition, the limited effect of catalyst amount on acetic acid conversion was investigated by Response Surface Methodology, and Historical Data Design. Moreover, k
1, k2, equilibrium constant and activation energy values were calculated using the pseudo-homogeneous kinetic model. The physical features of the catalysts were investigated by BET, XRD, FTIR, DRIFT, SEM/EDX, and MAPPING analysis methods.

Le Greenwashing publicitaire…20 ans plus tard
Authors: Vargas Elodie 
Published: August 2023

Cette contribution propose une analyse de l’évolution du Greenwashing dans les publicités pendant les 20 dernières années. Considérant la publicité dans le cadre du texte multimodal, elle montre, d’une part, comment le discours Greenwashing – à l’origine souvent caricatural – a évolué sémiotiquement pour devenir plus subtil et plus indécelable, et, d’autre part, comment de nouveaux acteurs, contraints par les injonctions sociétales dues au changement climatique sont apparus dans le paysage discursif. Le travail à la base de cette contribution repose sur un corpus composé de publicités papier issues de magazines français et allemands sur une période de plus de 32 ans de 1990 à 2022, soit plus de 2231 publicités papier. A celles-ci s’ajoutent des publicités onlines italiennes, américaines et anglaises ainsi que des publicités photographiées en France, en Allemagne et en Italie issues de panneaux Decaux.
