In der Kultur des Mittelalters nehmen Körper in ihrer äußeren Zeichenhaftigkeit eine zentrale Stellung ein. Dies gilt insbesondere für deformierte Körper, die aufgrund ihrer auffälligen Andersartigkeit immer wieder Thema wahrnehmungstheoretischer Diskurse werden. Das zeigt sich in zweierlei Hinsicht: Zum einen wird bereits in zeitgenössischen Quellen diskutiert, wie die körperlichen Besonderheiten den inneren Imaginationsapparat der Betrachter stimulieren, zum anderen zeichnen sich körperlich Deformierte zumindest in Kunst und Literatur auffallend häufi g durch gesteigerte Wahrnehmungsfähigkeiten aus. Die körperliche Deformation markiert dabei Grenzüberschreitungen. Sie weist über die Dinge hinaus auf ‚das Andere‘ – gleich ob es sich dabei um ein kulturell Anderes handelt, oder um das ‚Andere‘ der Diesseitigkeit: das Transzendente und Göttliche. Obgleich man für das Hoch- und Spätmittelalter kein einheitliches Körperkonzept annehmen kann, ist auffällig, an wie vielen Schnittpunkten der deformierte Körper ins Zentrum der Wahrnehmung rückt. Diese Vielfalt spiegelt sich auch in den Perspektiven verschiedener Fachdisziplinen, wie z. B. Kunst- und Literaturwissenschaft, Medizingeschichte, Dis/ability Studies oder Theologie in diesem Band, die den Besonderheiten des deformierten Körpers in seinem Verhältnis zur Epistemologie und eben zum "Anderen" gezielt nachspüren.

In this work, different nanocrystalline metals and alloys were investigated by a synchrotron-based in situ XRD mechanical testing technique in order to investigate the dominant deformation mechanisms. All tested samples show a succession and coexistence of several mechanisms, regardless of grain size, loading condition, or sample geometry. However, the relative shares of the individual mechanisms strongly vary and depend on parameters such as grain size, sample purity, and alloy composition.

With a wide spectrum of imaging capabilities, Earth observation offers several opportunities for the geoscience community to map and monitor natural and human-induced Earth hazards from space. The objective of this book is to collect scientific contributions on the development, validation, and implementation of satellite data, processing methods, and applications for mapping and monitoring of geohazards such as slow moving landslides, ground subsidence and uplift, and active and abandoned mining-related ground movements.The book includes research papers published in the Special Issue "Observing Geohazards from Space" of Geosciences, which provides a number of novel case studies demonstrating how Earth observation and remote sensing data can be used to detect and delineate land instability and geological hazards in different environmental contexts and using a range of spatial resolutions and image processing methods.

The proposed existence of the edge and screw dislocation in the 1930s, and the subsequent work showing that dislocation theory could explain the plastic deformation of crystals, represent an important step in developing our understanding of materials into a science. The continued work involved with characterization of dislocations and linking them to a variety of physical properties in both single and poly crystals have made enormous progress over the past 50 years. It is rare to find a technical application involving a material with any crystal structure that is not impacted by dislocations; mechanical properties, massive phase transformations, interphases, crystal growth, electronic properties, the list goes on. In many systems the properties is controlled by the formation of partial dislocations separated by a stacking fault; for example plastic deformation via deformation twinning. And finally, giant strides have been made in characterization and modeling of systems containing dislocations. The Special Issue on “Crystal Dislocations” is intended to provide a unique international forum aimed at covering a broad range of results involving dislocations and their importance on crystal properties and crystal growth. Scientists working in a wide range of disciplines are invited to contribute to this cause.Dr. K. Peter D. Lagerlof, Associate Professor of CeramicsGuest Editor

The high-temperature deformation behavior of oxide dispersion strengthened steels was investigated and correlated to the resulting microstructure using electron microscopy. Viscoplastic constitutive equations were developed from the results to model the deformation behavior.
