Spatial palindromes/palindromic spaces: spatial devices in Vitruvius, Mallarmé, Polieri, Perec and Libeskind

This thesis explores non-linear geometric texts and narratives in literature and architecture and the experience of space that is facilitated by them. The research focuses on the palindrome because it is a non-linear mathematical/geometrical device that is found both in literature and architecture. In language, the palindrome is expressed in the geometrical arrangement of words, letters or concepts in the text or the narrative; and, in architecture, as mirrored symmetries or palindromic proportions, measurements and distributions of elements in drawings and buildings. The primary aim of the thesis is to explore the spatial qualities of palindromes, and the experience of those qualities not only in text but also in architecture. This dissertation thus consists of two parts: the first examines Spatial Palindromes in terms of the spatial structures of selected texts and considers their relation to architecture; and the second examines Palindromic Spaces in terms of the spatial experiences created by and through palindromes in text and architecture. The first part, Spatial Palindromes, constructs an original history of the spatial qualities of palindromes by looking at the theory guiding the use of non-linear devices in texts and architecture. This history moves from the use of palindromes in the work of classical figures and scholars (Orpheus, Pythagoras and Vitruvius), to the Medieval and Renaissance practice of mnemonics (Frances Yates, Mary Carruthers), to early twentieth-century structural linguistics (Ferdinand de Saussure) and the group OuLiPo (Raymond Queneau, Franyois Le Lionnais) and, finally, to late twentieth-century post-structural linguistics (Jean Baudrillard.) The thesis argues that palindromes create spatial experiences both in texts and architecture. For this reason the second part, Palindromic Spaces, studies the nature of spatial experience in the fictions and designs of Stephane Mallarme, Jacques Polieri, Georges Perec, and Daniel Libeskind. According to Baudrillard the poetic space, hidden or revealed by the anagram and palindrome, is where the solid structure of language is "exterminated." This act of extermination, or the poetic space that palindrome reveals in language, opens up perception, memory and recollection to a spatial experience "that incorporates the recession of outcomes ad infinitum;" a self-generated, self-consumed or self-reflective conception of history and space that this thesis aims to explore in architecture

REFRACTIVE-INDEX OF CRYSTALS FROM TRANSMISSION AND REFLECTION MEASUREMENTS - MGO IN THE FAR-INFRARED REGION

In principle, the real n and imaginary k parts of the complex refractive index of a crystal can be determined by measuring, when possible, its transmission and reflection spectra. We show that it is possible to derive the frequency dependence of n and k in a simple way by using exact expressions for the interference-free transmittance and reflectance to describe low-resolution data. We also derive n and k data starting from one high-resolution spectrum. As an example, we have measured the room-temperature transmittance and reflectance of MgO in the far-infrared region. Reliable n and k data are then obtained in the frequency region 50-250 cm-1

Extramammary Paget’s Disease of the Vulva: Report of Two Cases

Extramammary Paget’s disease is a rare condition, affecting 6.5% of all patients with Paget’s disease. The most common extramammary site is the vulvar area. Although diagnosis in some patients is difficult to set, early diagnosis is of high importance in order to detect the irreversible progression of the lesion early and prevent distant metastasis. An 89-year-old female and a 69-year-old female presented within three months with an eczematous lesion with leukoplakia in the vulva. The incisional biopsy of the skin revealed extramammary Paget’s disease. Both patients underwent a surgical wide local excision of the lesion and the specimens were sent for histopathological examination. Extramammary Paget’s disease has a high potential for distant malignancies and local recurrence, dictating that surgical excision is the most efficient treatment. The rareness of the condition and the diagnostic difficulties underline the need for early skin biopsy, which is the most efficient diagnostic tool

Management of low rectal gastrointestinal stromal tumor with neoadjuvant therapy and transanal excision: a rare case report and review of the literature

Christopher Kosmidis,1,2 Konstantinos Sapalidis,1 Alexandros Tsakalidis,1 Stefanos Atmatzidis,1 Nikolaos Michalopoulos,1 Georgios Koimtzis,1 Georgia Karayannopoulou,3 Sofia Lypiridou,3 Nikolaos Varsamis,2 Georgios Kouklakis,2 Sofia Baka,2 Paul Zarogoulidis,1 Isaac Kesisoglou1 1Third Department of Surgery, AHEPA University Hospital, Aristotle University of Thessaloniki, Thessaloniki, Greece; 2Department of Oncology, Interbalkan Medical Center, Thessaloniki, Greece; 3Department of Pathology, Aristotle University of Thessaloniki, Thessaloniki, Greece Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. However, rectal GISTs represent only 5% of this category. We report a case of a rectal GIST treated with local excision after neoadjuvant therapy. Case presentation: A 41-year-old male patient presented with anal bleeding. Colonoscopy revealed a mass located 5 cm from the anal verge. Histological examination showed a GIST with immunohistochemical positivity for CD117 and CD34. Transanal local excision was performed after neoadjuvant therapy. Conclusion: Neoadjuvant immunotherapy for GISTs with unfavorable localization may facilitate local excision and avoid complications of more demanding operations. Keywords: gastrointestinal stromal tumor, rectal, neoadjuvant therapy, transanal excisio
