L. Del Corso - R. Luiselli, Literary Papyri from the Bodleian Library and Other Institutions. Contributions by A. Benaissa, N. Gonis, R. Hatzilambrou, M. Zellmann-Rohrer
No full textThis volume collects 20 Greek and Latin literary papyri, mostly unpublished, which are housed in several collections: some belong to the Bodleian Library, Oxford, others to Institutions scattered all around the world: the Biblioteca Medicea Laurenziana, Florence, the Bibliothèque de Geneve, the Library of Columbia University, New York, the IFAO, Cairo.
The variety of the institutions holding the papyri is matched by the diversity of contents, book formats, and scripts. The texts range from prose to poetry, from erudition to astrology and divination. Moreover, they come from a wide geographical area in the Egyptian chora, and range in date from the early Ptolemaic period to Late Antiquity’.
This collection of texts represents an example of the contribution which the study of papyri offers to the reconstruction of the classical literary heritage
Τὸ Μαρτυρολόγιο τοῦ Ἁγίου Ἰωάννου τοῦ Τραπεζουντίου σὲ ρουμανικὴ διασκευὴ (1643)
No full textThe Martyrologion of Saint Ioannis of Trapezus in a Romanian Adaptation (1643) This paper presents the Romanian adaptation of the Martyrologion of Saint Ioannis of Trapezus, which was composed by Metropolitan of Moldavia Varlaam (1632-1653). The adaptation has particular interest. So why is given information for the author, as well as some issues related to the book that hosts the Martyrologion. Also the causes of his pension, its contents, its differences compared with the text of monk Gregory and the consequences of the adaptations of the Greek Martyrologion prepared then in the Romanian and the Greek territories.
Polynuclear chloromercurate(II) systems in their chloropyridinium salts
No full textThe chloromercurate(II) salts of 2-, 3- and 4-chloropyridine display a variety of anion stoichiometries and structures, including the rare [Hg3Cl10]4− stoichiometry. 2-Chloropyridinium trichloromercurate(II), (I), (C5H5ClN)[HgCl3], monoclinic, P21/n, a = 9.094 (8), b = 18.143 (4), c = 12.902 (3) Å, β = 106.13 (4)° with Z = 8, has the [HgCl3]− stoichiometry, but the anions are infinite chains composed of [HgCl3]−, HgCl2 and Cl− moieties linked by longer Hg...Cl contacts. Hydrogen bonds link the cations to the formal Cl− ions. Tetrakis(3-chloropyridinium) decachlorotrimercurate(II), (II), (C5H5ClN)4[Hg3Cl10], monoclinic, P21/n, a = 7.522 (2), b = 28.046 (3), c = 9.165 (2) Å, β = 105.78 (2)° with Z = 2, has the rare [Hg3Cl10]4− stoichiometry and contains infinite one-dimensional double-stranded {([HgCl4]2−)2 [HgCl2]}
n
anionic chains made up of linear HgCl2 and distorted [HgCl4]2− entities linked together by longer Hg...Cl contacts. The HgCl2 moieties are joined by double [HgCl4]2− bridges. Hydrogen bonds link the cations to the sides of the anionic columns. Tetrakis(4-chloropyridinium) decachlorotrimercurate(II), (III), (C5H5ClN)4[Hg3Cl10], triclinic, P1¯, a = 9.907 (3), b = 13.226 (2), c = 7.282 (2) Å, α = 84.41 (2), β = 74.81 (2), γ = 87.34 (2)° with Z = 1, also has the [Hg3Cl10]4− stoichiometry and the same type of {([HgCl4]2−)2[HgCl2]}
n
anionic chains that were found in compound (II), but the formal HgCl2 and [HgCl4]2− moieties are more discrete with much weaker contacts linking the individual units. Bifurcated hydrogen bonds with the cations cross-link the anionic chains to form an infinite two-dimensional network. Second forms of the 3- and 4-chloropyridinium salts were also obtained. 3-Chloropyridinium trichloromercurate(II), (IV), (C5H5ClN)[HgCl3], monoclinic, P21/c, a = 7.243 (5), b = 22.145 (8), c = 12.320 (3) Å, β = 99.52 (3)° with Z = 8, has the [HgCl3]− stoichiometry, but the anions are infinite chains composed of distorted [Hg2Cl6]2− moieties. Bifurcated hydrogen bonds from the cations cross-link the anionic chains to form infinite two-dimensional layers. Bis(4-chloropyridinium) hexachlorodimercurate(II), (V), (C5H5ClN)2[Hg2Cl6], monoclinic, C2/m, a = 13.447 (3), b = 7.534 (2), c = 9.939 (2) Å, β = 97.48 (2)° with Z = 2, contains highly symmetrical discrete [Hg2Cl6]2−anions. Bifurcated hydrogen bonds from the cations interconnect the anions to form infinite one-dimensional chains.</jats:p
Dose coefficients for liver chemoembolisation procedures using Monte Carlo code
No full textThe aim of the present study is the estimation of radiation burden during liver chemoembolisation procedures. Organ dose and effective dose conversion factors, normalised to dose-area product (DAP), were estimated for chemoembolisation procedures using a Monte Carlo transport code in conjunction with an adult mathematical phantom. Exposure data from 32 patients were used to determine the exposure projections for the simulations. Equivalent organ (HT) and effective (E) doses were estimated using individual DAP values. The organs receiving the highest amount of doses during these exams were lumbar spine, liver and kidneys. The mean effective dose conversion factor was 1.4 Sv Gy-1 m-2. Dose conversion factors can be useful for patientspecific radiation burden during chemoembolisation procedures. © The Author 2016. Published by Oxford University Press. All rights reserved
A propósito de la métrica de las Crestomatías de Heladio de Antínoe y su repercusión en la interpretación de la obra
No full textAccording to Orion (5th century) and Photius (9th century), Chrestomathiae, the work of fourth-century Egyptian author Helladius of Antinoe, included some sections in iambic metre. Modern criticism, however, has assumed this metre for the whole work. This article aims to demonstrate that a literal reading of the sources indicates that they limit the use of iambus to the preface. As for the form of the rest of the work, certain evidences, both indicated by the sources and contained in it, lead us to think that it was written in prose. Finally, taking into account the content of the work and its formal structure, we try to place Helladius and his Chrestomathiae within the history of Greek literature.De acuerdo con Orión (s. V) y Focio (s. IX), la obra del autor egipcio del s. IV Heladio de Antínoe titulada Crestomatías presentaba una composición yámbica en alguna de sus partes. La crítica moderna, sin embargo, ha extendido este tipo de metro a toda la obra. En este artículo intentaremos demostrar que una lectura literal de las fuentes indica que estas circunscriben el uso de los yambos únicamente al prefacio. En cuanto a la forma del resto de la obra, determinados indicios, tanto señalados por las fuentes como contenidos en ella, nos llevan a pensar que estaba redactado en prosa. Finalmente, teniendo en cuenta el contenido de la obra y su estructura formal, intentaremos situar a Heladio y sus Crestomatías dentro de la historia de la literatura griega
