The Imam-caliph al-Mu‘izz al-Dīn Allāh undertook a series of monetary changes which were to have a monumental impact on all future Fā?imid coinage, would lead to many imitations even after the dynasty had fallen, and create an easily identifiable pattern that attracted medieval merchants and modern collectors. The fact that al-Mu‘izz's coinage went through three stages with slight variations in the wording and layout indicates that he was determined to create a new model for Fā?imid coinage which would distinguish it from the Aghlabid and ‘Abbāsid coinage that preceded and competed with it. In contrast, Sijilmasa coinage was so conservative in layout due to its role in the African trade. 相似文献

During soccer matches, performance decrements have been reported that relate to both physical abilities and technical skills. To investigate the effects of low-frequency electrical stimulation LFES (VeinoplusSport®, Ad Rem Technology, France) administered during half-time recovery on performance alterations during the second half. Twenty-two highly trained young players undertook a soccer-match simulation (SAFT90). During half-time, they were randomly assigned to LFES group or Placebo group. Each half was split into 3 bouts of 12 minutes. Following each bout, maximal strike speed (MSS), sprint test (ST), maximal sprint accelerations (MA) and metabolic power (MP) were determined in both groups. Arterial (AF) and venous flows (VF) were measured at rest and at the end of half-time. LEFS group exhibited beneficial effects on performance compared to the Placebo group with a likely effect for MSS, ST, MA, and a possible effect for MP. AF and VF increased statistically more in LEFS group compared to Placebo group. The use of specific calf-pump LFES during half-time of a youth simulated soccer match attenuated the decrease in performance during the second half compared to Placebo group. This effect is most marked at the beginning of the second half with regards to explosive parameters. 相似文献

This article examines the presentation of Muslim rulers from the early crusading period, 490–540/1097–1146 in six of the main chronicles written during the first half of the seventh/thirteenth century. It discusses the themes, ideas and topoi in each, demonstrating that the historians appear to have been divided into two ‘camps’ over their presentation of these rulers, based on their personal views of the rulers of their time. The article also examines why this division may have occurred, and considers its ramifications for modern scholarship of Arabic historiography, Islamic history and the history of the Crusades, in both the sixth/twelfth and seventh/thirteenth centuries. 相似文献

The purpose of the present study is to analyse the role played by an important female figure in early Shī?ite history. The person in question is Fi[ddot][ddot]a l-Nūbiyya, the servant-girl of Fā ?ima, the Prophet's daughter. After a long period of neglect by scholars, who have focused on what to their mind were figures of greater import, we shall here attempt to describe the role played by Fi[ddot][ddot]a in early Shī?ite history by way of analysing her biography and her close relations with Fā ?ima and members of the latter's family (?Alī, [Hdot]asan and [Hdot]usayn). We shall further describe what has been reported of Fi[ddot][ddot]a's personality, her family, her admiration for the Prophet's family, Qur?ānic verses which supposedly mention her, and the great respect in which she was held by Fā ?ima's family. 相似文献

Zusammenfassung. Traditionelle und deduktive Informationssysteme werden heute immer noch isoliert voneinander modelliert und implementiert.
Für die meisten Benutzer sind jedoch Systeme wichtig, die ihren allt?glichen Informationsbedarf decken und darüber hinaus
deduktive F?higkeiten besitzen. Der bekannte Entity-Relationship-Ansatz zur konzeptionellen Datenmodellierung wird in dieser
Arbeit so erweitert, da? damit solche integrierten Systeme modelliert werden k?nnen. Au?erdem wird eine Klassifizierung ableitbarer
Daten eingeführt, die dem Analytiker Hilfestellung bei der Frage gibt, welche ableitbaren Daten bei der Modellierung berücksichtigt
werden sollen und welche nicht.

Zusammenfassung. Dieser Beitrag enth?lt die wesentlichen konzeptionellen überlegungen zur Entwicklung eines flexiblen Workflow-Management-Systems.
Ausgehend von einer Diskussion m?glicher Modellierungsalternativen wird unter Verwendung objektorientierter Modellierungstechniken
ein Workflow-Meta-Schema entwickelt, das die relevanten Entit?ten klassifiziert und ihre Beziehungen abbildet. Anhand eines
Beispiels werden die getroffenen Entwurfentscheidungen ausführlich begründet. Schlie?lich werden Zust?nde und Zustandsüberg?nge
von Workflow-Instanzen beschrieben, und es wird diskutiert, wie dynamische Ver?nderungen von Workflows zur Laufzeit durchgeführt
werden k?nnen, um laufende Workflows dynamisch an ver?nderte Umweltbedingungen anzupassen.
