Authors: Both Maximilian , Müller Jochen , Diedrich Christian 
Published: November 2021

Zusammenfassung
Systeme im Bereich Industrie 4.0 sollen interoperabel miteinander agieren können. Damit dies automatisiert realisiert werden kann, müssen sie semantisch interoperabel sein. Hierfür fokussiert der aktuelle Industrie 4.0 Forschungsansatz einen semantisch homogenen Sprachraum. In diesem Paper wird eine Methode vorgestellt, die diesen Ansatz um heterogene Semantik erweitert. Die Abbildung unbekannter Vokabulare auf eine Zielontologie ermöglicht die Interaktionen heterogener Verwaltungsschalen. Basis der Abbildung sind Methoden aus dem Bereich Natural Language Processing. Hierzu werden auf ISO Standards vortrainierte language models und sentence embeddings kombiniert. Dies führt zu einer vielversprechenden Genauigkeit bei dem erstellten Evaluationsdatensatz, welcher unterschiedliche Semantiken für Identifikation- und Design-Teilmodelle des Projektes Pumpe 4.0 enthält.
An approach to adhesive bond characterisation using guided acoustic waves in multi-layered plates

Published: November 2021

Abstract
An approach for the non-destructive characterisation of adhesive bonds using guided ultrasonic waves is presented. Pulsed laser radiation is used to thermoacoustically excite broadband ultrasonic waves in a multi-layered sample, consisting of a metal plate adhesively joined to a polymeric layer using synthetic resin. The resulting signals are received by a purpose-built piezoelectric transducer. Varying the distance between excitation and detection yields spatio-temporal measurement data, from which the dispersive properties of the propagating waves can be inferred using a two-dimensional Fourier transform, assuming the plates to act as coupled waveguides. Coupled multi-layered waveguides show an effect referred to as mode repulsion, where the distance between certain modes in the frequency-wavenumber domain is assumed to be a measure of coupling strength. Measurements at different stages of curing of the adhesive layer are performed and evaluated. A comparison of the results shows changes in the dispersive properties, namely an increased modal bandwidth for the fully cured sample as well as an increased modal distance.
Jet characteristics of CO2–O2 mixed injection using a dual-parameter oxygen lance nozzle for different smelting periods

Published: November 2021

Abstract
The jet performance of an oxygen lance nozzle influences the smelting rhythm, smelting index, and energy consumption of a converter. Due to the complexity of the process of converter smelting, the changing temperature and gas composition in the converter significantly impact the jet characteristics of the oxygen lance nozzle in the smelting process; however, research on the change law of jet characteristics in different smelting periods is limited. In this study, we used Ansys Fluent 17.0, which is commercially available fluid simulation software, to simulate the variation of jet characteristics of a mixed injection comprising 6% CO2 and 94% O2; the mixed injection was tested using a dual-parameter oxygen lance nozzle in the early, middle, and late stages of smelting. The results show that the increase of CO concentration and ambient temperature in the converter lead to a decrease in the attenuation rate of jet velocity, improved independence of multiple jets, and an increase in the impact area of jets on the molten pool. Thus, when designing and employing oxygen lance nozzles, the influence of ambient temperature and furnace gas composition on jet characteristics must be considered.
Effect of Gd addition on non-isothermal and isothermal crystallisation of Cu–Zr–Al bulk metallic glass

Published: November 2021

Abstract
The crystallisation kinetics of (Cu46Zr46Al8)100–xGdx (x = 0, 2 and 4 at.%) bulk metallic glasses in non-isothermal and isothermal conditions were studied by differential scanning calorimetry and X-ray diffraction. X-ray diffraction analysis shows that the crystallisation product Cu10Zr7 changes to Cu10Zr7 and Cu2Gd in the presence of Gd in non-isothermal and isothermal conditions. Crystallisation activation energy was calculated using the Kissinger and Ozawa methods in non-isothermal conditions and using the Arrhenius model in isothermal conditions. The results show that Gd addition triggers an increase in the energy barrier during crystallisation. The Johnson–Mehl–Avrami model was employed to analyse the crystallisation kinetics in the isothermal condition. The Avrami exponent, n, for Cu46Zr46Al8 is more than 2.5, which demonstrates that the crystallisation is mainly governed by diffusion-controlled three-dimensional growth with increasing nucleation rate. Comparably, n for (Cu46Zr46Al8)98Gd2 and (Cu46Zr46Al8)96Gd4 is 1.5 < n < 2.5, which suggests that the crystallisation is mainly determined by diffusion-controlled three-dimensional growth with decreasing nucleation rate.
Eine moralische Ökonomie der Steuern?
Authors: Renault Rachel 
Published: November 2021

Abstract
This article analyses the conflicts over imperial taxation in 17th-18th century Germany at local level. As imperial taxes have been mostly studied for the 16th century and usually from the perspective of Vienna, observing them from below gives a completely different perspective. One can observe, in particular, very strong and long-lasting conflicts between subjects and territorial princes. The article defends the idea that taxation conflicts are not only due to the size of the tax burden, but also linked to social and political considerations. They provide an excellent vantage point for analysing the Empire from below and the popular politics that emerged within the imperial body politic.
Steuerzahlverhalten quantifizieren
Authors: Schönhärl Korinna 
Published: November 2021

Abstract
From the 1880s scientists developed methods to measure (dishonest) tax payment behaviour. The first part of this article provides an overview of these methods and their development. The second part enquires into the function of measuring methods in the societal discourse about (honest) tax payments. The tax morale research of Günter Schmölders, carried out in the 1950s and 1960s, is then examined as a case study. The focus of interest is on the political advice that Schmölders gave, as based on his empirical results, and on the ideal image of the citizen and society which underlay the scientific method.

Published: November 2021

Abstract
The assessment of a ship's ability to withstand environmental loads is very crucial. This research focuses on the strength assessment of 600 TEU container ship hulls against hydrostatic and hydrodynamic loads using finite element-based software. Parameter changes in the material types, hull thickness, and ship drafts were performed to compare the structural responses using deformation, strain, and von Mises stress criteria. All of the materials tested were acceptable, where the ASTM A131 Grade AH36 and ASTM A131 Grade AH32 materials have the lowest deformation values and strains. The simulation results regarding plate thickness variation, deformation, strain, and von Mises stress values were smaller as the thickness of the ship structure increased. Moreover, from the draft variation, the structural response due to environmental load was better as the draft of the ship increased.
Guaranteed upper bounds for the velocity error of pressure-robust Stokes discretisations
Authors: Lederer Philip L. , Merdon Christian 
Published: November 2021

Abstract
This paper aims to improve guaranteed error control for the Stokes problem with a focus on pressure-robustness, i.e., for discretisations that compute a discrete velocity that is independent of the exact pressure. A Prager–Synge type result relates the velocity errors of divergence-free primal and perfectly equilibrated dual mixed methods for the velocity stress. The first main result of the paper is a framework with relaxed constraints on the primal and dual method. This enables to use a recently developed mass conserving mixed stress discretisation for the design of equilibrated fluxes and to obtain pressure-independent guaranteed upper bounds for any pressure-robust (not necessarily divergence-free) primal discretisation. The second main result is a provably efficient local design of the equilibrated fluxes with comparably low numerical costs. Numerical examples verify the theoretical findings and show that efficiency indices of our novel guaranteed upper bounds are close to one.
Examples in the detection of heavy metal ions based on surface-enhanced Raman scattering spectroscopy

Published: November 2021

Abstract
Heavy metals have been widely applied in industry, agriculture, and other fields because of their outstanding physics and chemistry properties. However, heavy metal pollution is inevitable in the process of mass production and emission. Heavy metal ions will cause irreversible harm to the human body and other organisms due to their nondegradable nature even at low concentrations of exposure and ingestion. Therefore, it is of great significance for human health and ecological environment to develop high accuracy and sensitivity as well as stable techniques for detecting heavy metal ions. In recent years, surface-enhanced Raman scattering (SERS) spectroscopy has been regarded as a promising new technique for the determination of trace heavy metal ions on account of its special fingerprint identification capability, high sensitivity, rapid detection ability, and simple operation. This review summarized in detail the basic principles and strategies for detecting mercury ions, copper ions, arsenic ions, zinc ions, cadmium ions, lead ions, and chromium (VI) ions as well as the current challenges and future trends for the determination of heavy metal ions based on SERS technology.
Herd immunity levels and multi-strain influenza epidemics in Russia: a modelling study
Authors: Leonenko Vasiliy N. 
Published: November 2021

AbstractIn the present paper, we consider a compartmental epidemic model which simulates the co-circulation of three influenza strains, A(H1N1)pdm09, A(H3N2), and B, in a population with the history of exposure to these virus strains. A strain-specific incidence data for the model input was generated using long-term weekly ARI incidence and virologic testing data. The algorithm for model calibration was developed as a combination of simulated annealing and BFGS optimization methods. Two simulations were carried out, assuming the absence and the presence of protected individuals in the population, with 2017– 2018 and 2018–2019 epidemic seasons in Moscow as a case study. It was shown that strain-specific immune levels defined by virologic studies might be used in the model to obtain plausible incidence curves. However, different output parameter values, such as fractions of individuals exposed to particular virus strain in the previous epidemic season, can correspond to similar incidence trajectories, which complicates the assessment of herd immunity levels based on the model calibration. The results of the study will be used in the research of the interplay between the immunity formation dynamics and the circulation of influenza strains in Russian cities.

Published: November 2021

Abstract
Three cobalt-calixarene coordination frameworks, namely, {[Co4Cl(H4TC4AS)]4(HPO3)8}4− (CIAC-253), {[Co4Cl(H4TC4AS)]4(PO4)8}12− (CIAC-254) and {[Co4Cl(H4TC4AS)]3(Ph-PO3)6}3− (CIAC-255) were obtained by solvothermal reaction of a cobalt salt, sodium p-sulfonatothiacalix[4]arene (Na4H4TC4AS) and phosphate, phosphite and phosphonate ligands. In CIAC-253 and CIAC-254, the shuttlecock-like Co4Cl-(TC4AS) secondary building units (SBUs) are bridged by HPO3
2− or PO4
3− anions into two quadrilateral frameworks while in CIAC-255, the Co4Cl-(TC4AS) SBUs are linked into a triangular framework by phenylphosphonate anions. The supramolecular interactions between the phenyl groups of phosphonate and TC4AS play a crucial role in the formation of the triangle. Magnetic measurements revealed that all the cobalt(II) centers exhibit antiferromagnetic interactions.
Mulheres, História e Literatura
Authors: Franzini Letícia , Laks Daniel 
Published: November 2021

A metaficção historiográfica, como tratado por Linda Hutcheon (1991) em Poética do pós-modernismo, é o tipo de produção mais utilizada no âmbito pós-moderno, trazendo a mescla entre história e ficção, retomando o passado de maneira irônica e não nostálgica. Assim, observa-se uma escrita marcada pela presença da interface literatura e história, que contempla tanto a estratégia pós-moderna quanto a estratégia pós-colonial de produção. Ademais, é comum às obras de ambos, a representação do individuo subalterno, ou como coloca Linda Hutcheon, do ex-cêntrico. Pensando nisso, o artigo que se segue, visa analisar duas obras angolanas escritas por Pepetela, A geração da utopia (1992) e Se o passado não tivesse asas (2016), a partir das questões relacionadas ao pós-moderno e ao pós-colonial, observando a interface entre o literário ou o ficcional e a história, e a representação do subalterno, nesse caso a figura feminina.
Masculinidades negras no espelho
Authors: Silva Luciana de Mesquita , Santos Roberta da Silva Calixto dos , Nascimento Yago Eloi do 
Published: November 2021

Em tempos recentes, a literatura negra de autoria feminina tem ganhado proeminência social e se mostrado uma referência quando se trata de questionar as estruturas hegemônicas brancas, patriarcais e LGBTQIfóbicas tanto no campo literário, por meio de diferentes temáticas, perspectivas e estilos, quanto na sociedade como um todo. Dentre as diversas questões que ganham evidência nessas escritas está a construção de masculinidades negras. Neste artigo, analisamos dois contos de Cristiane Sobral publicados na obra Espelhos, miradouros, dialéticas da percepção (2011): “Afrodisíaco” e “Memórias”. Nosso objetivo é verificar de que forma estes contribuem para debates contra-hegemônicos ao desestabilizarem visões estereotipadas sobre corpos masculinos negros, a partir de temas como estigmatização e objetificação, afeto, paternidade e ancestralidade, além de trazerem uma renovação para o conjunto de produções de contos de autoria feminina no Brasil.
Dois poemas da concreta Maria do Carmo Ferreira
Authors: Bomfim Monalisa Medrado 
Published: November 2021

O presente trabalho analisou dois poemas de Maria do Carmo Ferreira: As parcas e De mim pra mins, com o objetivo de fornecer a poeta o reconhecimento histórico que cabe a ela, ao lado dos concretos, como alguém que não deixa a dever nem em referências poéticas, tampouco em articulação crítica. Para isso, levantou-se o fato de a poeta já ter publicado junto aos concretos na revista Invenção 5 e admitiu-se que a sua criação poética continua carregada de aspectos caros à poesia concreta. Para demonstrar que a poeta tinha consciência dos cercos que à invisibilizaram e que era por meio de sua poética que buscava transcendê-los, os poemas foram lidos a luz dos textos da Mística feminina, de Betty Friedan, que busca delinear o que é o feminino e como ele é perigoso para as mulheres. Assim, se Maria do Carmo pretendeu comer o mundo com seus poemas, aqui, dar-se-á garfo e faca a ela.
A infância na obra de Monique Revillion
Authors: Munari Ana Cláudia , Beilke Kelin Camila 
Published: November 2021

Neste trabalho trazemos alguns elementos que exemplificam os modos como a infância é representada nos livros Teresa, que esperava as uvas e O Deus dos insetos, que compõem a obra de Monique Revillion. Para tal, fazemos alguns apontamentos acerca dos conceitos de infância e memória, nos contextos social e literário. A memória, aqui, nos interessa a partir da ideia de um narrador adulto que relata um acontecimento da infância. A partir dessa perspectiva, selecionamos os contos que tratam desse tema e analisamos aqueles que trazem personagens crianças e suas ações. O viés de análise parte de um conhecimento sobre o corpus, que mostrou a relação íntima entre a infância e a violência como o subtema mais recorrente nas narrativas. A partir dessa leitura e desses exemplos, o trabalho deixa ver a diversidade de vivências apresentadas pelas infâncias na obra de Monique Revillion, bem como algumas implicações dessa relação entre infância e violência, caracterizando o que entendemos como uma “não infância”.
The rainbow shamrock
Authors: Cognard Gaëtan 
Published: November 2021

Abstract
This article focuses on article 28 (right to education), article 29 (goals of education) and article 30 (children from minority or indigenous groups) of the United Nations Convention on the Rights of the Child (UNCRC) and their implementation in the several national policies of Western Europe, especially the UK and Ireland, and to a lesser extent, France. The present research looked more particularly into the situation of children from two communities: Gypsy, Roma and Travellers (referred to as GRT) and Irish Travellers. Although they are from different backgrounds, the analysis proved relevant because of the bridges that exist between their cultures and lifestyles, and because of their minority status within larger dominant communities, placing their children in the frontline of the UNCRC battle. The text of the UNCRC itself was a starting point. The research was mainly based on a series of reports from governments, from organizations such as the Traveller Movement, on articles from newspapers, and testimonies from GRT children and Irish Travellers. The results showed that the implementation of articles 28 to 30 of the UNCRC was being by and large slowly carried out by the countries under study. Yet, national disparities were evident. Also, their national policies revealed different contexts. Ireland seemed to be paving the way for the inclusion of minorities within the educational system.
Multi-physics evaluation of carbonate-rich source rocks from high-resolution images
Authors: Eichmann Shannon L. , Sengupta Mita , Kotb Abdelrahman 
Published: November 2021

AbstractIn unconventional reservoirs, the pore space is hosted by a heterogeneous matrix with various minerals and organic components. This heterogeneity complicates petrophysical interpretation during hydrocarbon exploration. A digital rock physics study of thermal and electrical conductivity was conducted using high-resolution focused ion beam scanning electron microscopy images of carbonate-rich source rocks. Finite-volume simulation results are discussed in context of the sample heterogeneity and anisotropy and supported by comparisons to empirical equations and effective medium theory. The results show how the presence of organic matter, pyrite, and pore constrictions impacts application of empirical equations and simplified models to unconventional reservoirs.Graphic abstract
Experimental Study on Seepage and Fracture Characteristics of Cemented Rock Samples under Triaxial Stress
Authors: Li Chong , He Sifeng 
Published: November 2021

Abstract
To study the seepage and fracture characteristics of cemented rock strata, a series of triaxial seepage tests on cemented rock samples under different confining pressures and water pressures were carried out in this study. The triaxial strength, elastic modulus, volume strain, and the permeability of the cemented rock samples were analyzed by the seepage unit connection probability model and Kozeny-Carman model. Based on test results, the stress state of cemented rock samples was divided into four stages: nonlinear compaction stage, linear elastic stage, stress yield stage, and failure and postfailure stage. The triaxial strength of the cemented rock samples gradually increased with the increase of confining pressure but decreased with the increase of water pressure. The elastic modulus of the cemented rock sample increased with the increase of confining pressure but decreased with the increase of water pressure. Besides, the volume strain of the cemented rock sample was analyzed, and the volume strain change of the cemented rock sample was also classified into three stages: the increasing stage of crack volume strain, the stable stage of crack volume strain, and the decreasing stage of crack volume strain. Based on the results of triaxial seepage tests, the evolution of permeability was divided into the declining stage, increasing stage, and redescend stage. Through the seepage unit connection probability model and Kozeny-Carman model, the evolution of crack volume was obtained, and the evolution of crack volume with axial strain was also classified into three stages: the original pore closure stage, crack network expansion stage, and crack network closure stage. The permeability evolution and the crack volume evolution were also compared. The comparison results suggest that three stages of crack volume evolution are all ahead of three stages of permeability evolution, verifying that the crack propagation induces the formation of seepage channels in cemented rock samples. This research will provide a valuable reference for the study of instability and water inrush mechanism in cemented rock strata.

Authors: Wu Dan , Xi Cai-Fen , Zhang Ling , Xu Peng , Chen Zhi 
Published: November 2021

Abstract
Background

Nausea and vomiting is relatively frequent after painless digestive endoscopy. It not only occurs after surgery, but may also occur after painless digestive endoscopy. Here we study the characteristics and main risk factors associated with nausea and vomiting after painless digestive endoscopy.
Methods

A retrospective analysis of 1336 patients who had undergone painless digestive endoscopy in our hospital from January 2020 to May 2020 was performed. The incidence and timing of nausea and vomiting was examined, and the risk factors of nausea and vomiting of painless digestive endoscopy were analyzed.
Results

57 cases had nausea or vomiting (4.3% of 1336 cases, female to male ratio 3.38:1, average age 49.49 ± 13.30 years). 55 cases had nausea (4.1%) and 39 cases had vomiting (2.9%). Nausea and vomiting mostly occur within 6 hours after painless digestive endoscopy. In one-way analysis of variance, female, weight less than 60kg, diazoxide dose exceeding 2.5 mg, history of motion sickness, and history of smoke had significant correlation with nausea and vomiting, while female (OR=3.640, P=0.001), weight less than 60kg (OR 0.942, P=0.001), diazoxide dose exceeding 2.5 mg (OR=2.074, P=0.000) were independent risk factors of nausea and vomiting after painless digestive endoscopy by logistic regression analysis.
Conclusions

In our patients, female, weight less than 60kg and the dosage of diazoxide more than 2.5mg are the main risk factors of nausea and vomiting after painless digestive endoscopy. This study suggests that the dose of diazoxide no more than 2.5mg may reduce the occurrence of nausea and vomiting after painless digestive endoscopy.
