Abstract

At the turn of the twentieth and twenty-first century, the field of Arabic and Islamic studies became enriched by a number of multi-facetted scholarly theories challenging the traditional account on the early centuries of Islam. An author of one of them was the Israeli scholar Yehuda D. Nevo (1932–1992), working in archaeology, epigraphy and historiography. He devoted much of his career to the studying of Arabic rock inscriptions in the Negev desert, as well as to investigating literary and numismatic evidence of nascent Islam. In his theory, the gradual development of the Islamic faith, inspired by Abrahamism with an admixture of Judeo-Christianity, went through a stage of “indeterminate monotheism”. Not earlier than since the end of the second century A.H. one can speak of the formation of the dogmatic pillars of Islam, similar to those we know today. This paper is an attempt to sum up Nevo’s insightful input into the field of modern Islamic & Quranic studies today. Although controversial and unorthodox, many later researchers repeatedly refered to Nevo’s plenty of inspiring theses in their quest for facts on Islamic genesis lost in the maze of time and shifting memory of generations.

Abstract

The paper exemplifies chosen textual variants extant in Qur’an versions in the Islamic world, focusing on printed readings according to Ḥafṣ ʿan ʿĀṣim and Warš ʿan Nāfiʿ, against the historical background of Ibn Muǧāhid’s qirā’āt reform (10th century C.E.). The studied issue is part of and sheds light on a broader problem – the quest after elaborating a critical text edition of the Qur’anic text based on the oldest and best manuscripts. The preliminary conclusion is that neither Ibn Muǧāhid nor the oldest, surviving works by Muslim scholars devoted to the Qur’anic qirā’āt did actually record the factual state of the oral tradition from the 7th century, but that the variants of the oral tradition as codified in the 10th century have their origin only in the late written tradition (probably also only from the 10th century, possibly not much older).

Abstract

The paper presents a neutronic analysis of the battery-type 20 MWth high-temperature gas cooled reactor. The developed reactor model is based on the publicly available data being an ‘early design’ variant of the U-battery. The investigated core is a battery type small modular reactor, graphite moderated, uranium fueled, prismatic, helium cooled high-temperature gas cooled reactor with graphite reflector. The two core alternative designs were investigated. The first has a central reflector and 30×4 prismatic fuel blocks and the second has no central reflector and 37×4 blocks. The SERPENT Monte Carlo reactor physics computer code, with ENDF and JEFF nuclear data libraries, was applied. Several nuclear design static criticality calculations were performed and compared with available reference results. The analysis covered the single assembly models and full core simulations for two geometry models: homogenous and heterogenous (explicit). A sensitivity analysis of the reflector graphite density was performed. An acceptable agreement between calculations and reference design was obtained. All calculations were performed for the fresh core state.
