Corrosion Behavior and Mechanical Properties of Metallic Materials
No full textGlobally, more than USD 400 million/year is spent on corrosion protection and productivity losses due to corrosion. Corrosion, a process associated with chemical/electrochemical reactions, often has deleterious consequences on mechanical properties, ultimately resulting in the degradation of a material. Metallic components, widely employed in various industries, i.e., oil, gas, marine, nuclear, fuel cells, medicine, and electricity generation, often suffer from severe corrosion, which might be detrimental to service life and even cause serious accidents. Meanwhile, some extreme corrosive environments are also the main restriction on the applications of advanced metallic materials with excellent mechanical properties. Thus, understanding corrosion behavior and its effect on mechanical properties will always be of great practical significance to the development and application of metallic materials. This Special Issue aims to provide a research forum for reporting corrosion behavior andrelated mechanical properties, chemical compositions, and microstructures of metallic materials, in order to address existing corrosion challenges and assist in the development of super corrosion-resistant materials. Topics of interest include, but are not limited to, the topics mentioned above, as long as they enhance our knowledge of corrosion protection

Das Affektregime weiblicher Altersarmut
No full textAltersarmut betrifft in erster Linie Frauen. Sie ist das Ergebnis geschlechtsspezifischer Arbeits- und Lebensverläufe, politischer Versäumnisse und sozialstaatlicher Rückzüge und nicht zuletzt Produkt eines sozialen Sicherungssystems, das einseitig auf Lohnarbeit zentriert ist. Doch was bedeutet es, Armut im Alter zu erleben? Alexandra Rau wirft einen schonungslosen Blick auf die affektive Dimension weiblicher Altersarmut. Ausgehend von ethnografischen Porträts zeigt sie, dass Gefühle wie Scham, Einsamkeit, Angst, Melancholie oder Kränkung keine individuellen Phänomene sind, sondern Ausdruck gesellschaftlicher Ungleichheiten. Gleichzeitig prägen sie die Handlungsmöglichkeiten jener Frauen, deren Leben von prekären Beschäftigungsverhältnissen und Fürsorgeverantwortung bestimmt waren. Die empirische Studie liefert intime Einblicke in die alltäglichen Verstrickungen einer Generation, für die das Versprechen eines finanziell abgesicherten ›wohlverdienten Ruhestands‹ obsolet geworden ist – und macht deutlich: Altersarmut ist auch eine tief emotionale Erfahrung. Eine, die Vereinzelung fördert, politische Mobilisierung erschwert und affektive Zumutungen produziert. In kulturwissenschaftlicher Schärfe entwickelt Rau das Konzept der Affektarbeit weiter und eröffnet damit eine neue Perspektive auf ein drängendes gesellschaftliches Problem. https://creativecommons.org/licenses/by-sa/4.0
Affirmation und Kritik des modernen Zeitregimes bei Friedrich Schiller, Heinrich Heine und Gottfried Keller
No full textSince the eighteenth century, societies have been increasingly orienting the way they think and act around the future. This is not the result of a natural process, but can be attributed to a complex discursive formation: the modern temporal regime. This study outlines the positions toward this key concept of modernity taken by Friedrich Schiller, Heinrich Heine, and Gottfried Keller, which oscillate between affirmation and critique
With a Pure Conscience
No full textOffers new perspectives on freedom of conscience and religious liberty by tracing their origins to the Middle Ages, thereby challenging the common assumption that these core tenets of modernity were products of the EnlightenmentDeeply committed to the formation of a just and sacred society, medieval theologians and canonists developed sophisticated arguments in defense of religious liberty and freedom of conscience. They did so based upon the conviction that each human person possesses an inalienable right to pursue his or her spiritual vocation and to inquire into the truth, provided that such pursuits were not deemed injurious to the commonweal. For this was an age in which all power, whether secular or sacred, was held to be exercised legitimately only insofar as it served the common good. Within these basic parameters there existed a domain of personal freedom guaranteed by natural and divine law that could not be infringed by either secular or ecclesiastical authority. Theologians and canonists did not countenance blind obedience to reigning powers nor did they permit Christians to stand idle in the face of manifest transgressions of sacred tradition, constitutional order, and fundamental human rights. Such foundational principles as the sacred domain of conscience, freedom of intellectual inquiry, dissent from unjust authority, and inalienable personal rights had been carefully developed throughout the later Middle Ages, hence from the twelfth through the fifteenth centuries. Contrary to the popular conception, therefore, the West did not need to wait for the Protestant Reformation, or the Enlightenment, for these values to take hold. In fact, the modern West may owe its greatest debt to the Middle Ages. With a Pure Conscience sheds further light on these matters in a variety of contexts, within and without the medieval university walls, and often amid momentous controversies. This was a robust intellectual culture that revered careful analysis and vigorous disputation in its relentless quest to understand and defend the truth as it could be ascertained through both reason and revelation.With a Pure Conscience: Christian Liberty before the Reformation is available from the Knowledge Unlatched on an open-access basis

Therefore, the traditional and unconventional methods used to detect and assess well integrity are the focus of this issue. In particular, the processing method, calculation standard, and visual analysis of well monitoring data are used in well integrity assessments. Factors may include the reliability of wellbore flow models, effective information extraction from real-time wellbore monitoring data, and coupled evaluation models involving all barrier elements of wellbore integrity. This research can be based on practical experience in the field or through detailed simulations
»Das Natürlichste, was eine Frau haben kann«
No full textDas »Tabuthema« Menstruation ist in den vergangenen Jahren verstärkt zum Gegenstand öffentlicher Auseinandersetzungen und zu einem Symbol feministischer Körperpolitiken geworden. Doch während die Blutung einerseits mit Schlagworten wie Enttabuisierung oder Empowerment belegt wird, prägen gleichzeitig historische Kontinuitäten der Pathologisierung, Naturalisierung und Vergeschlechtlichung ihre gesellschaftlichen Verhandlungen. Sophie Bauer untersucht aktuelle Praktiken rund um die Blutung und entwickelt ausgehend von dieser Analyse das Konzept der Menstrualität. Menstrualität beschreibt dabei einen relationalen, materiell-diskursiven Prozess, der in besonderem Maße durch die Gleichzeitigkeit einer Stabilisierung und Destabilisierung von Kategorien wie Geschlecht und Natur geformt wird. Als zentrales Moment gegenwärtiger Praktiken der Menstrualität identifiziert die Studie eine Logik der Sorge und bringt empirische Beobachtungen mit feministischen Sorgetheorien ins Gespräch. https://creativecommons.org/licenses/by-sa/4.0/deed.d
Accounting for the Self, Locating the Body
No full textKael Reid’s stories, lyrics, and poems delve into the complexities of queer existence, exploring themes of relationality, embodiment, movement, and place. A white settler, lesbian singer-songwriter turned genderqueer researcher and educator, Reid reflects on their life journey from a farm in southwestern eastern Canada to the mountains of western Canada and back. Reid’s narratives cover diverse experiences: a moment of reflection while cooking lunch over a fire in the woods as a youth, sexual assault, watching a lesbian docu-drama, drug abuse, waking up beside a woman for the first time, homophobic violence, an unplanned pregnancy, a past life experience while hiking, singing with a musical companion in a run-down biker bar, finding love, and undergoing gender-affirming top surgery. Through these tales, Reid connects to the more-than human world and captures the essence of being human.Publishe
