Investigation of an Egyptian Mummy board by Using Clinical Multi-slice Computed Tomography

A modern approach to the diagnosis of artistic heritage makes use of non-destructive techniques which avoid damage to artworks or signs of interaction with the analytical technique used. For this reason, today, the employment of X-rays to study artistic heritage is quite widespread. Computed tomography (CT) Imaging was first used as specialized medical diagnostic tool in the early 1970s. Today, CT scanners have become more common, and non-destructive three-dimensional imaging has found an increasing number of uses in different areas such as materials research, geology, archaeology, and museum conservation. In this work, a new generation of clinical CT (based on the Dual Energy and multi-slice acquisition principle) is used to investigate an Egyptian wooden mummy board with a total acquisition time of 93.23 seconds and a voxel size of 0.078?×?0.078?×?1.5?mm. The use of two distinct techniques of image post-processing, the two-dimensional multi-planar reconstruction (MPR) and the three-dimensional volume rendering technique (VRT) allowed us to: evaluate the state of conservation of the mummy board, determine how the wooden object was implemented, recognize a nineteenth-century intervention of consolidation, and advance the hypothesis that the wooden planks were reused. In particular, we highlight the use of the cardiovascular and pulmonary filter with VRT reconstruction, which allows a virtual elimination of different parts of the mummy board to investigate those areas otherwise accessible only by removing parts of the board and thus damaging the work.  相似文献   

Power Struggles,Regulation and Responsibility     

Sian Barber 《Media History》2018,24(1):99-114

This article explores the relationship between the British Board of Film Classification (BBFC) and government during the implementation of the Video Recordings Act (VRA). It considers the public Parliamentary debates about the VRA, and places them alongside private correspondence between the Home Office and the BBFC, and internal BBFC material from the recently catalogued James Ferman papers held at the BFI. As well as exploring the introduction of the VRA, this article also aims to briefly consider its implications for the BBFC, how they set about interpreting and implementing its stringent recommendations and how this impacted upon the organisational working practices of the Board. While the VRA was without doubt one of the most significant pieces of legislation within the history of film regulation in Britain, the time is ripe for its reappraisal and with it a re-evaluation of the role played by the BBFC in securing statutory regulatory powers.  相似文献   

论影视翻译中的文化差异处理     

牟丽 《自贡师范高等专科学校学报》2006,21(4):104-106,114

语言和文化是紧密相关的，各民族和国家之间存在着的文化差异必然反映在语言中。这种体现在语言中的文化差异给翻译造成了极大的障碍，因而一直为译者所关注。对于文化差异的处理，在翻译界一直有“归化”和“异化”之争。影视翻译作为文学翻译的一个分支，既与一般文学翻译有共同之处，又有着自身的特性和原则。本文结合影视节目的特点，提出了影视翻译处理文化差异时应遵循的三大原则及相应的翻译手段，并以大量的实例予以说明。  相似文献

从人文心态的演变看中国喜剧电影的发展     

李军辉 《信阳师范学院学报(哲学社会科学版)》2003,23(2):102-105

中国喜剧电影从诞生之日起,就一直摇摆在各种电影类型之间,因为没有合适的“化身份”而步履维艰,究其原因是因为受到了中国特殊的化传统和特定的社会氛围的制约和影响。本试图从人心态的演变来分析中国喜剧电影发展的轨迹和变化的特点。  相似文献   

Measurement of conversion efficiency of soft X-ray from 0.35μm laser-irradiated aluminum planar targets     

Shu-xi Ren  Hong-liang Ma Ph. D.  Rong-qing Yi  Shen-ye Liu 《上海大学学报(英文版)》2006,10(3):224-227

Conversion efficiency of soft X-ray from 0.35 μm pulse laser-irradiated aluminium planar target at laser intensities 10¹³–10¹⁵ W/cm² on the Xingguang-II facility (laser energy 5–90 J, focal spot ⊃ Ф 200 μm full width of half maximun (FWHM) 400–800 ps) was measured. A simple model was given to explain soft X-ray conversion efficiency. In this model, because of the heat conduction from the laser-heated spot, the conversion was very small at lower irradiance limit, while at higher limit it was bounded by the energy lost in blow off plasma. Consequently, at the laser intensity around 2×10¹⁴ W/cm², the X-ray conversion efficiency reaches a maximum.

后现代影视：政治与道德话语的放逐     

曾耀农 《丹东师专学报》2006,8(1):71-73

中国近期影视后现代性强化了世俗愿望的追求，拆解了英雄创业的神话，在放遂各种政治与道德权威话语的同时，破坏了具有历史主义特征的精神模式，使影视更加贴近百姓的感受经验。  相似文献
