WeChat 2.0. Überlegungen zum kommunikativen Potenzial der Applikation angesichts aktueller Tendenzen von Messenger-Kommunikation
Authors: Szurawitzki Michael 
Published: March 2022

Zusammenfassung
Im Beitrag werden Überlegungen zum kommunikativen Potenzial der chinesischen Messaging-Applikation WeChat angesichts aktueller Tendenzen von Messenger-Kommunikation angestellt. Es werden die wesentlichen funktionalen Änderungen/Ergänzungen gegenüber der ersten Beschreibung im germanistisch-linguistischen Kontext (Szurawitzki 2019b) in den Blick genommen. Nach der Einführung folgt ein Abschnitt zum Forschungsstand, in dem sich auf einschlägige Arbeiten zu WeChat fokussiert wird. In Ergänzung von Szurawitzki (2019b) werden nachfolgend Bemerkungen zu neueren Funktionalitäten von WeChat getätigt, die so bisher in der Germanistischen Linguistik noch nicht beschrieben worden sind, aber mit Blick auf die Fragestellung und das kommunikative Potenzial der Applikation Beachtung finden (müssen). Im Anschluss daran plädiere ich für terminologische Neuerungen im Bereich der Erforschung von Chat- und Messengerkommunikation, da die sich ändernde mediale Umgebung mit noch mehr multimodalen Möglichkeiten existierende Termini zwar nicht obsolet macht, diese Termini aber meines Erachtens die kommunikativen Konstellationen in ihrer Komplexität nicht mehr abdecken. Auf der Basis des bis dahin Gesagten schließt der Beitrag mit einem Abschnitt ab, in dem die Zukunft von WeChat und Messengerkommunikation vor dem Hintergrund von Trends anderer populärer Applikationen wie z. B. Discord, das ursprünglich ein Tool für Gamer:innen war, auch interkulturell reflektiert wird.
Transdisciplinary research methods and complexity theory in applied linguistics: introduction to the special issue
Authors: Hiver Phil , Al-Hoorie Ali H. 
Published: March 2022

AbstractComplexity theory/dynamic systems theory (CDST) has captured the imagination of many in the field of applied linguistics (Larsen-Freeman, Diane & Lynne Cameron. 2008.Complex systems and applied linguistics. Oxford: Oxford University Press; Ortega, Lourdes & Zhao Hong Han (eds.). 2017.Complexity theory and language development: In celebration of Diane Larsen-Freeman. Amsterdam: John Benjamins). As recent syntheses of the growing number of CDST-informed strands of applied linguistics research illustrates, it has emerged as an important influence on applied linguists’ thinking (see Larsen-Freeman, Diane. 2017. Complexity theory: The lessons continue. In Lourdes Ortega & Zhao Hong Han (eds.),Complexity theory and language development: In celebration of Diane Larsen-Freeman, 11–50. Amsterdam: John Benjamins). The fact that CDST has continued to permeate questions throughout the field is to be expected and welcomed.
System mapping simplex spaces: facilitating change in L2 educational contexts from a complexity theory perspective
Authors: Fogal Gary G. 
Published: March 2022

Abstract
The claim that educational contexts are dynamic, complex spaces is hardly a novel one. Yet, to date limited explicit treatment in the literature engages L2 classrooms as such. This paucity is partially explained by methodological concerns with investigating diverse and contextually dense places in ways that capture the richness of these environments. While no single method can mitigate this concern, system mapping can help researchers explore system dynamics through a mapping technique that diagrams system variables through the interpretive lens of relevant stakeholders. Stakeholders engage with variables relative to a guiding statement, question, or objective meaningful to the system’s development or maintenance, thus providing insights into interactions across and beyond the conventional teacher–student interface. System mapping is particularly useful for problem solving and developing in-depth understandings of relations across system components. After describing and expanding on system mapping and its uses in education research, this work moves through a sample study in the L2 writing context to demonstrate its utility.
Cx43 upregulation in HUVECs under stretch via TGF-β1 and cytoskeletal network
Authors: Shi Yumeng , Li Xinbo , Yang Jin 
Published: March 2022

Abstract
Many physiological and pathophysiological processes in cells or tissues are involved in mechanical stretch, which induces the gap junction gene expression and cytokine TGF beta changes. However, the underlying mechanisms of the gap junction gene expression remain unknown. Here, we showed that the mRNA and protein levels of Cx43 in human umbilical vein endothelial cells (HUVECs) were significantly increased after 24 h stretch stimulation, and TGF beta1 (not TGF beta2) expression was also upregulated. Administration of TGF beta1 into HUVECs without stretch also induced upregulation of Cx43 expression. However, SB431542, a specific inhibitor of the TGF beta1 receptor, blocked the Cx43 protein upregulation caused by TGF beta1. Further, the increase of Cx43 protein expression under the stretch condition was partially blocked by SB431542; it was also partially blocked by simultaneous administration of anti-TGF beta1 monoclonal neutralization antibody. Importantly, the upregulation of Cx43 induced by stretch was blocked by the administration of actin and microtubule inhibitors, while NEDD4, a key element in mediating Cx43 protein ubiquitination and degradation, was not changed under the stretch condition. In conclusion, upregulation of Cx43 expression under the 24 h stretch condition is mediated via TGF beta1 receptor signaling pathway, and it also involves the actin and microtubule cytoskeletal network.

Published: March 2022

Abstract
In this article, the Ansys Workbench was used to carry out the finite element analysis of 15 kW wind turbine blades with different damaged positions and different damaged degrees. The results show that the change rate of natural frequency, displacement modes, and strain modes of the blades increased with the increase in the damage degree; the change rate of the natural frequency and displacement modes of the blade decreased with the increase in the speed, while the change rate of the strain modes increased; the change allocation ratio of the displacement modes and strain modes after the damage was more obvious at the damage location than other positions, which can be used to locate the damage position of the blade; the change allocation ratio of strain modes is higher than the change allocation ratio of displacement modes when the damage degree is the same, which means that the recognition effect of the strain modes is more significant than that of the displacement modes.

Published: March 2022

AbstractConcrete is one of the most extensively utilized building materials that can be produced, and has the potential to release a significant quantity of CO2into the environment. In this research, through studying lightweight (LW) concrete, attempts are made to produce environmentally friendly LW concrete with high strength using nanosilica rather than part of the cement and waste glass powder instead of aggregates. Recycled polypropylene fibers are used to increase the concrete’s compressive strength and nonlinear behavior. The use of glass powder was 20, 25, and 30% of the weight of aggregates, the consumption of nanosilica was 1, 2, and 3% of the weight of cement, and the consumption of recycled fibers (FORTA Ferro-Green) was 0.5, 1, and 1.5% of the weight of cement. Leca is also utilized as a LW aggregate. According to 7- and 28-day experimentation results and field emission scanning electron microscope analysis, the best sample had 1.5% fiber, 3% nanosilica, and 25% waste glass powder, and had a compressive and tensile strengths of roughly 1.7 and 1.6 times, respectively, those of the control specimen after 28 days. Also, using 3% nanosilica instead of cement can reduce greenhouse gas emissions by about 3%.
The surface modification effect on the interfacial properties of glass fiber-reinforced epoxy: A molecular dynamics study
Authors: Deng Jiangang , Song You , Lan Zhenbo , Xu Zhuolin , Chen Yanming , Yang Bing , Hao Huali 
Published: March 2022

Abstract
In this work, the effect of common functional groups, namely hydroxyl, formyl, carboxyl, and amine groups on the interfacial behavior of surface-modified glass fiber-reinforced epoxy is investigated at molecular scale. The interfacial properties of the epoxy/silica coated with different functional group systems are quantified by performing pulling test using the steered molecular dynamics simulations. It is found that the system with hydroxyl groups has a relatively lower interfacial interaction, exhibiting an adhesive failure mode. When partial hydroxyl groups are replaced by carboxyl, amine, and formyl groups, respectively, the interfacial interactions are increased and these systems exhibit a cohesive failure mode where failure happens in the epoxy close to interface. A relatively higher force is required for the adhesive debonding, while more energy can be dissipated for the cohesive debonding. Because the increased interfacial interactions can prevent the mobility of polymer chains, and delay the propagation of micropores in the matrix, leading to the epoxy matrix with a high ability of energy absorption. Our work provides an insight into how functional groups affect the interface debonding behavior of glass fiber-reinforced epoxy, offering a guideline for control of the interfacial properties of such composites through surface modification techniques.
Molecular dynamics study of deformation mechanism of interfacial microzone of Cu/Al2Cu/Al composites under tension
Authors: Chen Yao , Wang Aiqin , Guo Zishuo , Xie Jingpei 
Published: March 2022

Abstract
The micromechanical behavior of an Al/Al2Cu/Cu multilayer with characteristic crystal orientation during uniaxial tensile deformation was investigated by molecular dynamics. The simulation results showed that under tensile loading, the dislocation nucleates at the Cu/Al2Cu heterogeneous interface and moves toward the Cu layer along the {111} crystal plane. The deformation mechanism is intralayer confinement slip. As the dislocations proliferated, interactions between them occurred; resulting in the formation of insertion stacking faults and deformation twins in the Cu and Al layers. However, no dislocation lines were generated in the Al2Cu layer during tensile deformation. As the load increased, the stress concentration at the Al2Cu/Al interface led to the fracture of the complex. In addition, the microplastic deformation mechanism and mechanical properties of Al/Al2Cu/Cu composites at different temperatures and strain rates were significantly different. These results revealed the microdeformation mechanism of laminated composites containing brittle phases.
Development of monazite glass-ceramic wasteforms for the immobilisation of pyroprocessing wastes

Published: March 2022

AbstractPyrochemical reprocessing is a potential route for the reprocessing of fuels from next-generation reactors. Lanthanide fission products may be separated from the reprocessing salt by a number of methods; however, salts may be entrained in the resultant product. This work demonstrates conceptual monazite glass-ceramic wasteforms based on the quarternary (100−x)(10Na2O–36Fe2O3–54P2O5)–xLa2O3 (x = 5, 10, 15), with La2O3 as a surrogate for the lanthanide oxide waste stream. Samples were produced by the melting of La2O3 with a sodium-iron-phosphate glass frit and characterised by XRD and SEM–EDX. The monazite phase was successfully formed at all waste loadings with clear segregation of La to the crystalline phase; however, high La2O3 loading (>10 mol%) was found to destabilise the glass system resulting in gross crystallisation. These initial results indicate that monazite glass-ceramics are promising wasteforms for this waste stream.

Published: March 2022

Heart failure (HF) remains a serious problem in Russian and world health care due to the growing morbidity and mortality from complications of heart failure, despite the development and implementation of programs for the early detection and treatment of heart failure in asymptomatic patients. Currently, a large number of new biological markers have been studied that could serve as a laboratory tool for diagnosing and predicting the course of heart failure, but only brain natriuretic peptides have found application in real clinical practice. Renalase is a recently discovered cytokine that is synthesized by the kidneys and released into the blood. To date, seven subtypes of renalase have been found, each of which plays a different physiological role in the human body. Renalase is usually positioned as a signaling molecule that activates cytoprotective intracellular signals, leading to a decrease in blood pressure and protection of the heart muscle. The concentration of renalase freely circulating in the bloodstream of an adult is approximately 3–5 ng / ml. Currently, the level of renalase is determined by the enzyme immunoassay with a detection range of 3.12 to 200 ng / ml, while the minimum detectable concentration of the marker is less than 1.38 ng / ml. The presence of missense polymorphism of renalase is associated with myocardial dysfunction. Data from animal and human studies have shown that renalase plays a key role in the metabolism of catecholamines and in cardioprotective processes. Studies have shown the contribution of renalase to the occurrence of cardiovascular diseases: ischemic heart disease, arterial hypertension, diabetes mellitus, and aortic stenosis. Moreover, detailed protocols of multicenter prospective studies have demonstrated that functional polymorphism of the renalase gene was associated with myocardial hypertrophy in patients with aortic stenosis, hypertension, metabolic syndrome, unstable angina pectoris and stable forms of coronary artery disease, as well as in patients receiving renal replacement therapy. Based on these data and further studies, renalase has been proposed as a predictive biomarker of ischemia in patients with coronary microvascular dysfunction, as well as a predictor of clinically significant progression of chronic kidney disease in patients with cardiovascular diseases.Our review presents data on the role of renalase in heart failure. Further study of the structure and function of renalase, as well as future clinical studies, will allow determining the diagnostic, prognostic and, possibly, therapeutic significance of this biological marker in HF and other cardiovascular diseases.

The level of prevalence and risk factors of strabismus among children and adolescents, depending on the type of settlements in the Ganja-Gazakh economic district (Azerbaijan)
Authors: Abdiyeva Yazgyul 
Published: March 2022

BACKGROUND: Strabismus as a pathological condition complicating the visual function and affecting the behavioral functions of children is often in the center of attention of numerous studies. The presence of regional differences in the strabismus prevalence makes this problem a relevant to study issue in the regions of Azerbaijan.
AIM: To assess the prevalence rate of strabismus among children depending on the settlement type.
MATERIALS AND METHODS: A prospective observation of a sample of children aged 519 years was carried out; the sample size was determined taking into account the size of the margin of sampling error less than 5%. 300 children at the age 59, 1014, 1519 years (150 boys and 150 girls) in a large town (Ganja) and rural settlements of Ganja-Gazakh region (2700 children in total) have been observed. In all children, an ophthalmologic examination was performed by specialists of the mobile team of the National Ophthalmological Center named after academician Z. Aliyeva.
RESULTS: Strabismus was found in children aged 5-19 years in 4.6 0.7% of cases in a large town and in 2.7 0.5% of cases in rural settlements. Significant differences of prevalence rate of strabismus by age and gender were not confirmed.
CONCLUSIONS: In the region, the incidence of strabismus among children aged 519 years was 3.8 0.4%. In a large town, the risk of strabismus among children is high. In children with strabismus, refractive errors and perinatal conditions (prematurity) are often found.
