Each series of books is dedicated to a research topic in the development of teacher education. From a broad international perspective, it conducts in-depth discussions on hot topics in the fields of teaching, scientific research and professional development of English teachers. It has both rich theoretical knowledge and freshness. The classroom examples of this article aim to provide practical and effective theoretical guidance and practical reference for the education and development of language teachers at home and abroad.
Andy Kirkpatrick is a professor in the Department of Languages and Linguistics at Griffith University in Australia. His main research directions are teaching English as a foreign language, applied linguistics and rhetoric. As an outstanding scholar in the field of world English research, the author has been committed to exploring the key issues in the theory and practice of this field in his successful career for more than 40 years. The research and practice of World English and English as a global lingua franca have emerged in Asia. And communication has had a huge impact. This book brings together a series of impressive representative articles by the author. I believe readers will be inspired by them to explore and study important issues in the world of English.No Full Tex
Semi-transparent central stop in high-resolution X-ray ptychography using Kirkpatrick-Baez focusing
No full textA ptychographic coherent X-ray diffractive imaging (PCDI) experiment has been carried out using 7.9 keV X-rays and Kirkpatrick-Baez focusing mirrors. By introducing a semi-transparent central stop in front of the detector the dynamic range on the detector is increased by about four orders of magnitude. The feasibility of this experimental scheme is demonstrated for PCDI applications with a resolution below 10 nm. The results are compared with reference data and an increase of resolution by a factor of two is obtained, while the deviation of the reconstructed phase map from the reference is below 1%
Focus characterization of the NanoMAX Kirkpatrick–Baez mirror system
No full textThe focusing and coherence properties of the NanoMAX Kirkpatrick–Baez mirror system at the fourth-generation MAX IV synchrotron in Lund have been characterized. The direct measurement of nano-focused X-ray beams is possible by scanning of an X-ray waveguide, serving basically as an ultra-thin slit. In quasi-coherent operation, beam sizes of down to 56 nm (FWHM, horizontal direction) can be achieved. Comparing measured Airy-like fringe patterns with simulations, the degree of coherence |μ| has been quantified as a function of the secondary source aperture (SSA); the coherence is larger than 50% for SSA sizes below 11 µm at hard X-ray energies of 14 keV. For an SSA size of 5 µm, the degree of coherence has been determined to be 87%
Versatility of a hard X-ray Kirkpatrick-Baez focus characterized by ptychography
No full textIn the past decade Kirkpatrick-Baez (KB) mirrors have been established as powerful focusing systems in hard X-ray microscopy applications. Here a ptychographic characterization of the KB focus in the dedicated nano-imaging setup GINIX (Göttingen Instrument for Nano-Imaging with X-rays) at the P10 coherence beamline of the PETRA III synchrotron at HASLYLAB/DESY, Germany, is reported. More specifically, it is shown how aberrations in the KB beam, caused by imperfections in the height profile of the focusing mirrors, can be eliminated using a pinhole as a spatial filter near the focal plane. A combination of different pinhole sizes and illumination conditions of the KB setup makes the prepared optical setup well suited not only for high-resolution ptychographic coherent X-ray diffractive imaging but also for moderate-resolution/large-field-of-view propagation imaging in the divergent KB beam
Organ printing
No full textOrgan printing techniques offer the potential to produce living 3D tissue constructs to repair or replace damaged or diseased human tissues and organs. Using these techniques, spatial variations along multiple axes with high geometric complexity can be obtained.. The level of control offered by these technologies to develop printed tissues will allow tissue engineers to better study factors that modulate tissue formation and function, and provide a valuable tool to study the effect of anatomy on graft performance.\ud

In this chapter we discuss the history behind substrate patterning and cell and organ printing, and the rationale for developing organ printing techniques with respect to limitations of current clinical tissue engineering strategies to effectively repair damaged tissues. We discuss current 2-dimensional and 3-dimesional strategies for assembling cells as well as the necessary support materials such as hydrogels, bioinks and natural and synthetic polymers adopted for organ printing research. Furthermore, given the current state-of-the-art in organ printing technologies, we discuss some of their limitations and provide recommendations for future developments in this rapidly growing field

Sub-5 nm hard x-ray point focusing by a combined Kirkpatrick-Baez mirror and multilayer zone plate
No full textCompound optics such as lens systems can overcome the limitations concerning resolution, efficiency, or aberrations which fabrication constraints would impose on any single optical element. In this work we demonstrate unprecedented sub-5 nm point focusing of hard x-rays, based on the combination of a high gain Kirkpatrick-Baez (KB) mirror system and a high resolution W/Si multilayer zone plate (MZP) for ultra-short focal length f. The pre-focusing allows limiting the MZP radius to below 2 mu m, compatible with the required 5 nm structure width and essentially unlimited aspect ratios, provided by enabling fabrication technology based on pulsed laser deposition (PLD) and focused ion beam (FIB).

Graeme Kirkpatrick, Aesthetic Theory and the Video Game
No full textAesthetic Theory and the Video GameGraeme KirkpatrickNew York: Manchester University Press, 2011. Images, bibliography, index. 247 pp. $25.95 cloth. ISBN: 9780719077180 Graeme Kirkpatrick's study of aesthetic theory and video games seeks to apply aesthetic theory to what some view as a garish, popularized, and mass-produced cultural form. What do video games have to do with aesthetics after all? Kirkpatrick takes this question head on and argues that video games are a"historically specific instance of an aesthetic form," and as such they should be viewed through the lens aesthetics to be understood (p. 1). Over the course of six chapters, Kirkpatrick discusses the newness of what games bring to aesthetics. For the author, the newness of games is a specific way of approaching the text through the body, as a participant rather than as an audience.Drawing on the work of Markku Eskelinen (a founder of gamestudies.org), Kirkpatrick demonstrates the difference between games and stories. As Eskelinen notes, when we are thrown a ball, we do not expect it to tell us stories. This example becomes Kirkpatrick's starting point for an exploration of games as texts that expect us to play along, take part in, and initiate the progress of the experience. He pushes Eskelinen's comments further by asserting that the act of playing can be meaningful without being subjected to interpretation. The act is its own meaning and its own goal.Despite Kirkpatrick's initial claim that play does not have to be interpreted, he does commit interesting and thoughtprovoking acts of interpretation. For instance, in chapter 5, "Meaning in Virtual Worlds," he interprets the structure of video games as a constant revisiting of loss, and he points to how it is described as a joyless pleasure (p. 187). In this discussion, he demonstrates through strong and engaging analysis the connections between game criticism and the cultural criticism of Walter Benjamin and Frederic Jameson.In Kirkpatrick's chapter called "Ludology, Space, and Time," he positions the ludology (the study of games) of Espen Aarseth and Jesper Juul in the context of traditional aesthetic theory. He weaves the loose ends of structuralist game studies into the aesthetic traditions and understandings that the ludologists originally rejected, claiming that game scholarship was independent of them. These original ludologists did this to avoid having games reduced and understood only in the image of the previous, more static texts dominating the field of literature and aesthetics. Yet while this chapter performs the necessary task of positioning ludology in relation to aesthetic theory, it also leaves a lot to future discussio
