Sheila Canby, Deniz Bayazid, Martina Rugiadi (eds.). The Seljuqs and their Successors. Art, Culture and History

Le présent volume rassemble les Actes du colloque organisé à l’occasion de l’exposition Court and Cosmos: The Great Age of the Seljuqs qui s’est tenue au Metropolitan Museum of Art de New York en 2016. L’ouvrage se compose de seize chapitres articulés en six parties. La première partie, « Introduction » (pp. 1-31) regroupe trois chapitres respectivement signés par les trois éditrices, puis Carol Hillenbrand et enfin Robert Hillenbrand (respectivement « Editors’ Introduction », « What is Speci..

Half of the World: The Social Architecture of Safavid Isfahan, 1590-1722. Los Angeles, Mazda, 1999, 206 p.

Ce livre, court mais dense, est le neuvième titre de la prestigieuse collection « Islamic Art and Architecture Series » (A. Daneshvari, R. Hillenbrand, B. O’Kane). Le projet de l’A. n’est pas de refaire une étude sur l’architecture des monuments de la « Moitié du monde » (les travaux de qualité sont nombreux), mais plutôt de montrer par qui et pourquoi ces monuments ont été construits. En dernière instance, son but est de parvenir à une meilleure compréhension de la société locale, du système..

Continuous catalytic decomposition of methane

Water is conserved by employing sequence of reactions whereby 75 percent of methane from Sabatier reaction is decomposed to solid carbon and hydrogen; hydrogen is then separated from residual methane and utilized in usual Sabatier reaction to reduce remaining metabolic carbon dioxide

Dynamic specification of vowels in Hijazi Arabic

\ua9 2024 De Gruyter Mouton. All rights reserved.Research on various languages shows that dynamic approaches to vowel acoustics – in particular Vowel-Inherent Spectral Change (VISC) – can play a vital role in characterising and classifying monophthongal vowels compared with a static model. This study’s aim was to investigate whether dynamic cues also allow for better description and classification of the Hijazi Arabic (HA) vowel system, a phonological system based on both temporal and spectral distinctions. Along with static and dynamic F1 and F2 patterns, we evaluated the extent to which vowel duration, F0, and F3 contribute to increased/decreased discriminability among vowels. Data were collected from 20 native HA speakers (10 females and 10 males) producing eight HA monophthongal vowels in a word list with varied consonantal contexts. Results showed that dynamic cues provide further insights regarding HA vowels that are not normally gleaned from static measures alone. Using discriminant analysis, the dynamic cues (particularly the seven-point model) had relatively higher classification rates, and vowel duration was found to play a significant role as an additional cue. Our results are in line with dynamic approaches and highlight the importance of looking beyond static cues and beyond the first two formants for further insights into the description and classification of vowel systems

Deferoxamine Preventable Hepatocellular Damage, Following Hemorrhagic Shock

To examine the role of iron in mediating hepatocellular damage during reperfusion after hemorrhagic shock, we studied five groups of n=4 or 5 dogs, bled to reduce mean arterial pressure to 35 mmHg (± 5mrnHg) for three hours and subsequently treated 20 minutes prior to reinfusion of shed blood with either 0.9% saline, 5 ml/kg; deferoxamine, 50 μg/kg in 0.9% saline; 6% pentastarch solution, 5 ml/kg; deferoxamine covalently bound to 6% pentastarch, 50 μg/kg; or iron loaded deferoxamine in 0.9% saline. Saturation of iron binding capacity increased during hemorrhagic shock and remained high in all but the def eroxamine pentastarch treated group. Serum iron levels were significantly lower in animals treated with saline or iron loaded deferoxamine. Serum alanine aminotransferase (ALT), a specific marker for hepatocellular injury in the dog, was measured as an indicator of hepatic reperfusion injury. During shock, ALT did not change significantly from the normal in any group. After reperfusion, however, ALT rose sharply in animals reperfused without iron chelators, from a mean baseline value of less than 36 U /L to a post-reperfusion plateau of 5509 ± 2260 U /L at four hours, a pattern suggesting hepatic reperfusion injury. Iron loaded deferoxamine control dogs, also showed a substantial rise in ALT activity to 6287 ± 2134 U/L four hours after reperfusion. However, dogs treated with free deferoxamine showed significantly smaller elevations in ALT to only 655 ± 139 U /L (P \u3c0.05). Histologic evaluation of liver sections showed significantly smaller areas of necrosis in both of the deferoxamine treated groups compared to other groups. These findings suggest that deferoxamine preventable reperfusion injury of the liver, perhaps involving the iron catalyzed Haber-Weiss reaction, may play a role in the pathophysiology of hemorrhagic shock
