Aeschylus' Scholia in ms. Ath. Iber. 209: Two Examples
No full textAmong the scholia to Aeschylus’ Persae preserved by the ms. Ath. Iber. 209 (12th–14th century), the one to v. 14 takes over a glossographic exegesis of the words ἱππότης and ἱππηλάτης as φυγάς, using it for an ἱππεύς which probably left the interpreters uncertain of the difference between ἄγγελος and ἱππεύς. The scholium on vv. 869–871 recalls two passages of Eustathius’ commentary to the Iliad, with a clear simplification; it belongs to a section, in the ms., which offers mostly scholia belonging to the A-family, which, according to Smith, derive from a lost commentary by Tzetzes, who, in turn, would have recalled Eustathius’ commentary to the Iliad. Nevertheless, a thorough analysis of this particular case shows that the situation is more complex. Finally, in this scholium we find the fragment of an anonymous author, which could be tragic, and, in particular, Euripidean
Pig Eye Cornea Transplantation from Maslahah Ath-Thufi's Perspective
No full textIslamic Law prohibit pork, while corneas from pig eyes can be used as a substitute for human corneas that are blind due to corneal abnormalities by transplanting corneas from either human corneas or corneas from pig eyes. Pig corneas have close genetic and anatomical similarities to human corneas so that rejection of the transplanted organ tissue is minimal.Transplantation of pig corneas as a replacement for human corneas does not yet have a clear law in the Al-Quran and Al-Hadith, so the law needs to be established, in this case the author approaches the law from the perspective of Maslahah from Najamuddin Ath-Thufi who states that Maslahah is a shariah proposition ' strongest where Allah Ta'aala prioritizes maintaining the benefit of His servants as a gift from Allah.This article is a descriptive study where the author only takes and processes data sourced from literature related to the research topic with the tentative conclusion that transplantation of pig corneas as a replacement for human corneas is permitted for the benefit of humans if it is necessary to overcome blindness so that they can see again
Mechanistic Complexity of Asymmetric Transfer Hydrogenation with Simple Mn-Diamine Catalysts
No full textThe catalytic asymmetric transfer hydrogenation (ATH) of ketones is a powerful methodology for the practical and efficient installation of chiral centers. Herein, we describe the synthesis, characterization, and catalytic application of a series of manganese complexes bearing simple chiral diamine ligands. We performed an extensive experimental and computational mechanistic study and present the first detailed experimental kinetic study of Mn-catalyzed ATH. We demonstrate that conventional mechanistic approaches toward catalyst optimization fail and how apparently different precatalysts lead to identical intermediates and thus catalytic performance. Ultimately, the Mn-N,N complexes under study enable quantitative ATH of acetophenones to the corresponding chiral alcohols with 75-87% ee.</p
The Syrian unification and the Nūr ad-Dīn jihād in Ibn al-Athīr\'s chronicle, Kitāb al-Kāmil fi l-ta\'rīkh
No full textEm nossa dissertação, estudamos o excerto da crônica Kitāb al-Kāmil fi l-ta\'rīkh, de Ibn al-Athīr, que relata os anos de governo de Nūr ad-Dīn. Nossa pesquisa é dividida em três partes. Na primeira, apresentamos o autor e sua obra, a origem e a composição da crônica, além do debate historiográfico sobre a obra. Na segunda, abordamos os gêneros retóricos da Retórica de Aristóteles e a aplicação de dois destes gêneros, epidítico e deliberativo, na composição do discurso de Ibn al-Athīr. Na terceira, realizamos uma síntese das definições de jihād tanto no Alcorão quanto nos tratados jurídicos muçulmanos e mostramos como o nosso autor se apropria deles para legitimar as ações de Nūr ad-Dīn e construir, por meio de seu discurso, a figura do biografado como um exemplo de governante.In our dissertation, we study the extract of Ibn al-Athīr\'s chronicle, Kitāb al-Kāmil fi l-ta\'rīkh, reporting the years of Nūr ad-Dīn\'s governmet. Our research is divided into three parts. The first presents the author and his work, the chronicles origin and the composition, besides presenting the historiographical debate on the work. The second approachs the rhetoric genres of Aristotles Rhetoric and the use of two of these genres, epideictic and deliberative, at the construction of Ibn al-Athīr\'s discourse. The third discusses the definitions of jihād both at Coran and at muslims juridical treatises, indicating how our author uses them to legitimate Nūr ad-Dīn\'s action in order to elaborate him, through his discourse, as an example of ruler
Ibn Jarir Al-Thabari's Interpretation of the Word “Hurun In” in the Qur'an with a Linguistic Approach
No full textHurun 'in is a beauty that Allah promises to his servants as a pleasure for those who fear him. One of the pleasures that Allah promises to his servants, a companion in heaven, is the pure white angels with black eyeballs and beautiful eyes. A figure who has a beautiful nature and character that is always awake from goodness and beauty. The purpose of this study was to search for a broader meaning of the meaning of hurun 'in. In this study, the author uses the research method of tafsir maudhu'i by collecting verses in the Qur'an that have the same meaning. And then the author discusses with the tahlili method which refers to the book of tafsir ath-Tahabari by Abu Ja'far Muhammad bin Jarir Ath-Thabari. The results of this research in the view of Abu Ja'far Ath-Thabari the author found several meanings of hurun 'in his tafseer in interpreting the verses of hurun 'in
Testing the randomness in the sky-distribution of gamma-ray bursts
No full textWe have studied the complete randomness of the angular distribution of gamma-ray bursts (GRBs) detected by the Burst and Transient Source Experiment (BATSE). Because GRBs seem to be a mixture of objects of different physical nature, we divided the BATSE sample into five subsamples (short1, short2, intermediate, long1, long2) based on their durations and peak fluxes, and we studied the angular distributions separately. We used three methods, Voronoi tesselation, minimal spanning tree and multifractal spectra, to search for non-randomness in the subsamples. To investigate the eventual non-randomness in the subsamples, we defined 13 test variables (nine from the Voronoi tesselation, three from the minimal spanning tree and one from the multifractal spectrum). Assuming that the point patterns obtained from the BATSE subsamples are fully random, we made Monte Carlo simulations taking into account the BATSE's sky-exposure function. The Monte Carlo simulations enabled us to test the null hypothesis (i.e. that the angular distributions are fully random). We tested the randomness using a binomial test and by introducing squared Euclidean distances in the parameter space of the test variables. We concluded that the short1 and short2 groups deviate significantly (99.90 and 99.98 per cent, respectively) from the full randomness in the distribution of the squared Euclidean distances; however, this is not the case for the long samples. For the intermediate group, the squared Euclidean distances also give a significant deviation (98.51 per cent)
A generalization of the incidence energy and the laplacian-energy-like invariant
No full textFor a graph G and a real number a, the graph invariant s? (G) is the sum of the ath powers of the signless Laplacian eigenvalues and ?? (G) is the sum of the ath powers of the Laplacian eigenvalues of G. In this study, for appropriate vales of alpha, we give some bounds for the generalized versions of incidence energy and of the Laplacian-energy-like invariant of graphs. © 2018 University of Kragujevac, Faculty of Science.

The manuscript tradition of Procopius' Wars, Books V-VIII : reconstruction of family y in the light of a new extant manuscript (Athos, Lavra H-73)
No full textThis present thesis examines the manuscript tradition of the family y of Procopius' Wars
Books VNIII, in the light of a hitherto unknown extant manuscript (Ath), Athos, Lavra
codex H-73 (728). It comprises an introduction and four sections (1-4). The introduction
gives information on the author and his works concentrating on his major historical work,
the Wars.
This is followed by Section 1 containing an analytical codicological and
palaeological description of codex Ath. As the codex does not contain a colophon, a
possible thirteenth/fourteenth century dating is based on palaeographical and
codicological evidence.
Section 2 examines the position of the codex in the stemma codicum, proposed by
the latest editor of the text, Jacob Haury (1905-12). A collation of the text with the
principal manuscripts (K and L) of the two families, z and y, shows that Ath belongs to the
y family. A further collation of Ath with all other extant manuscripts of this family,
illustrates the importance of Ath in the tradition of the text.
Section 3 gives a description and updated information of all manuscripts of family
y, before the relation is examined and the stemma codicum is reconstructed on the basis of
a series of propositions.
The thesis concludes with Section 4, which places the production of Ath and other
manuscripts, containing Procopius' works and other early Byzantine historiographical
texts, in the general context of the intellectual milieu of the Palaeologan period
Cardiovascular disease risk in middle-aged ultra-endurance athletes
No full text2018 Fall.Includes bibliographical references.Background: It is widely accepted that aerobic exercise has the ability to reduce cardiovascular disease (CVD) risk. However, recent studies suggest that volumes of exercise that greatly exceed physical activity guidelines may be damaging to the heart. Currently, it is unclear if individuals who train for ultra-endurance races are at an elevated risk of developing CVD compared to those that perform lower amounts of physical activity. Purpose: To use traditional and novel measures of CVD risk to determine if individuals that train for ultra-endurance races have a greater CVD risk compared to participants that engage in recreational physical activity. Methods: We studied two groups of healthy, middle-aged adults (40-65 y); Control (CON, n=18) subjects included individuals who were meeting current physical activity guidelines and the athletes (ATH, n=25) had been training for ultra-endurance events for 10 years. We used cardiac computed tomography (CT) to calculate coronary artery calcium scores (CACS) and magnetic resonance imaging (MRI) to assess for myocardial fibrosis (MF). Vascular function was evaluated using carotid-femoral pulse wave velocity (cfPWA) and flow-mediated dilation (FMD). 10-Year coronary heart disease (CHD) risk was also determined using a risk score calculator. Results: CACS > 0 was observed in 2 CON and 8 ATH; however, the presence of CAC was not significantly different between groups (P>0.05). Additionally, no participants in CON or ATH had MF. CON had higher cfPWV compared to ATH (6.9±0.2 vs 6.2±0.2 m/s, P0.05). Furthermore, there were no group differences in CHD risk (CON; 1.6±0.3 vs ATH; 2.4±0.6 %, P>0.05). Conclusion: ATH training for ultra-endurance races are not at a greater risk of experiencing a cardiac event than individuals that meeting current physical activity guidelines
