This article examines the kambārī vessel now housed at the Museum of the Frankincense Land, Salalah, Oman, built for display in 1980. This sewn‐plank boat type, used for fishing and lightering in Dhofar, is discussed in the context of other similar vessels in Oman, South Yemen, and Somalia. As one of only five known surviving kambaris, a detailed account of this vessel's construction is given accompanied by an accurate pictoral record.  相似文献

The Turban has been worn by Muslims since the early period of Islamic history. This paper examines the significance of the turban in Twelver Shi‘ism. It argues that the turban and its color have been used to enhance the social and religious status of the descendants (sayyids) of the Prophet Muhammad. The paper also discusses the importance attached to the method of tying the turban and demonstrates how social pressure forced scholars to abandon a practice established by the Prophet and Imams. It will also argue that the method of trying the turban was used as an ideological tool among Shi‘i scholars.  相似文献

This paper argues for a rediscovery and reassessment of the contributions that humanistic approaches can make to critical and radical geographies. Based on an exploration of the archives of Anne Buttimer (1938–2017) and drawing upon Paulo Freire's notion of conscientização (awareness of oppression accompanied by direct action for liberation), a concept that inspired the International Dialogue Project (1977–1988), I explore Buttimer's engagement with radical geographers and geographies. My main argument is that Buttimer's notions of “dialogue” and “catalysis”, which she put into practice through international and multilingual networking, should be viewed as theory‐praxes in a relational and Freirean sense. In extending and putting critically in communication literature on radical pedagogies, transnational feminism and the “limits to dialogue”, this paper discusses Buttimer's unpublished correspondence with geographers such as David Harvey, William Bunge, Myrna Breitbart, Milton Santos and others, and her engagement with radical geographical traditions like anarchism, repositioning “humanism” vis‐à‐vis the fields of critical and radical geography.  相似文献

Sir Jack Goody has been exploring the changing dynamics of East/West relations in numerous brilliant works. The key question concerns the dominance of the West since the eighteenth century. Are there features unique to the West which lead to its superiority both in arms and in culture? Or, were the last 200 years a mere passing moment in the “longue durée”? The history of the Ottomans from the thirteenth to the twentieth century provides a good background for Goody’s critical arguments. They turn out to be an unexpectedly tough adversary in the First World War, and yet the Empire fails. Does the Ottoman experience and the Turkish transformation provide new insights for the role of Islam in politics? Are there lessons to be learnt in the conduct of military operations against radical Islamic groups concerning the need for good, responsible and, above all, just governance?  相似文献

Geologic carbon capture and storage (CCS) is an option for reducing CO2 emissions, but leakage to the surface is a risk factor. Natural CO2 reservoirs that erupt from abandoned oil and gas holes leak to the surface as spectacular cold geysers in the Colorado Plateau, United States. A better understanding of the mechanisms of CO2‐driven cold‐water geysers will provide valuable insight about the potential modes of leakage from engineered CCS sites. A notable example of a CO2‐driven cold‐water geyser is Crystal Geyser in central Utah. We investigated the fluid mechanics of this regularly erupting geyser by instrumenting its conduit with sensors and measuring pressure and temperature every 20 sec over a period of 17 days. Analyses of these measurements suggest that the timescale of a single‐eruption cycle is composed of four successive eruption types with two recharge periods ranging from 30 to 40 h. Current eruption patterns exhibit a bimodal distribution, but these patterns evolved during past 80 years. The field observation suggests that the geyser's eruptions are regular and predictable and reflect pressure and temperature changes resulting from Joule–Thomson cooling and endothermic CO2 exsolution. The eruption interval between multiple small‐scale eruptions is a direct indicator of the subsequent large‐scale eruption.  相似文献

A gas geochemical precursor anomaly was identified prior to the October 2008 Nový Kostel (Czech Republic) earthquake swarm with a peak magnitude ML of 3.8. This anomaly was observed as a deviation of CO2 concentrations from the long‐term annual CO2 concentration trend in the gas extracted from the scree at the Nový Kostel and Old?i?ská gas monitoring stations, which are directly above the Plesná valley‐Po?átky and Mariánské Lázně fault systems. Both sites are located within the major focal zone of the NW Bohemian swarm earthquake region at the northern edge of the Cheb Basin. A decrease in CO2 concentration started at Nový Kostel in September 2008, 17 days before the swarm, opposite to the usually increasing annual trend in the autumn period, and ended with a nearly coseismic drop immediately prior to the onset of the first swarm. The CO2 concentrations at Old?i?ská, deviating from the annual trend, did not further increase after August 2008. The calculated horizontal strain field, based on the data of two permanent Global Navigation Satellite Systems stations, proved there was horizontal compression in this period. The increasing compression along the Plesná valley‐Po?átky and Mariánské Lázně fault systems during the stress build‐up reduced the fault permeability prior to this earthquake swarm as indicated by the decrease in CO2 concentration. The 17‐day duration of the earthquake precursor at Nový Kostel and about 65 days at Old?i?ská lie within the range of the precursor times that are hypothesized worldwide for an ML = 3.8 earthquake. The nature of earthquake precursors and their origin are discussed, for example, as an indication of changed fault permeability by stress build‐up in the case of the Nový Kostel swarm earthquake precursor or as fault opening in other cases.  相似文献

This study investigates the Wangfu Depression of the Songliao Basin, China, as a natural analogue site for Fe migration (bleaching) and mineralization (formation of iron concretions) caused by reducing CO2‐bearing fluids that leak along fractures after carbon capture, utilization, and storage. We also examined the origin of fracture‐filling calcite veins, the properties of self‐sealing fluids, the influence of fluids on the compositions of mudstone and established a bleaching model for the study area. Our results show that iron concretions are the oxidative products of precursor minerals (pyrite and siderite) during uplift and are linked to H2S and CO2 present in early stage fluids. The precipitation of calcite veins is the result of CO2 degassing and is related to CO2, CH4, and minor heavy hydrocarbons in the main bleaching fluids. In our model, fluids preferentially enter high‐permeability fracture systems and result in the bleaching of surrounding rocks and precipitation of calcite veins. The infilling of calcite veins significantly decreases the permeability of fractures and forces the fluids to slowly enter and bleach the mudstone rocks. The Fe2+ released during bleaching migrates to elsewhere with the solutions or is reprecipitated in the calcite veins and iron concretions. The formation of calcite veins reduces the fracture space and effectively prevents fluid flow. The fluids have an insignificant effect on minerals within the mudstone. In terms of the chemistry of the mudstone, only the contents of Fe2O3, U, and Mo change significantly, with the content of U increasing in the mudstone and the contents of Fe2O3 and Mo decreasing during bleaching.  相似文献

ABSTRACT

Konstantin Mihailovi?, a Serb born in Novo Brdo, was taken by the Ottomans and became a janissary in Mehmet II’s army. After he returned to the Christian side, he penned a report on Ottoman governance, religion, military structures and tactics. It explained by organisational advantages, fairness to subjects of all faiths coupled with deceit vis-à-vis enemies, divisions within Christendom, and providential history’s retributive measures, why the ‘heathen’ had the upper hand. But the author, Konstantin, remained discreet. Autobiographical details on his years as a janissary are scarce. He had risen high in the Ottoman system. While conveying his expertise about the enemy to Christian courts was his key to a further career, he also had to conceal that he had been an important member of the janissary corps, and probably had converted to Islam. The first imperative, sharing expertise, complicated the second, self-silencing, and made it impossible to dissimulate fully.  相似文献

Knowledge about human subsistence and the role of animal economy in the Islamic period of south‐east Arabia is still sketchy. The analysis of faunal remains from the coastal fort at Luluyyah (Sharjah, UAE), dated to the late thirteenth and early fourteenth century CE, provides some information. People depended on marine resources and domestic animals, a trait observable in the region since the Neolithic. Livestock breeding was not particularly developed. Judging by the distribution of their skeletal remains, the animals were slaughtered at the fort, implying that they either lived there or reached it alive.  相似文献

The aim of this study was to determine the process–structure–property relationships between the pre‐ and post‐CO2 injection pore network geometry and the intrinsic permeability tensor for samples of core from low‐permeability Lower Triassic Sherwood Sandstone, UK. Samples were characterised using SEM‐EDS, XRD, MIP, XRCT and a triaxial permeability cell both before and after a three‐month continuous‐flow experiment using acidic CO2‐rich saline fluid. The change in flow properties was compared to those predicted by pore‐scale numerical modelling using an implicit finite volume solution to the Navier–Stokes equations. Mass loss and increased secondary porosity appeared to occur primarily due to dissolution of intergranular cements and K‐feldspar grains, with some associated loss of clay, carbonate and mudstone clasts. This resulted in a bulk porosity increase from 18 to 25% and caused a reduction in mean diameter of mineral grains with an increase in apparent pore wall roughness, where the fractal dimension, Df, increased from 1.68 to 1.84. All significant dissolution mass loss occurred in pores above c. 100 μm mean diameter. Relative dilation of post‐treatment pore area appeared to increase in relation to initial pore area, suggesting that the rate of dissolution mass loss had a positive relationship with fluid flow velocity; that is, critical flow pathways are preferentially widened. Variation in packing density within sedimentary planes (occurring at cm‐scale along the ‐z plane) caused the intrinsic permeability tensor to vary by more than a factor of ten. The bulk permeability tensor is anisotropic having almost equal value in ‐z and ‐y planes but with a 68% higher value in the ‐x plane (parallel to sedimentary bedding planes) for the pretreated sample, reducing to only 30% higher for the post‐treated sample. The intrinsic permeability of the post‐treatment sample increased by one order of magnitude and showed very close agreement between the modelled and experimental results.  相似文献

Alevis, the largest religious minority of Turkey, also living in Europe and the Balkans, are distinguished from both Sunnis and Shi?ites by their latitudinarian attitude toward Islamic Law. Conceptualizing this feature as “heterodoxy,” earlier Turkish scholarship sought the roots of Alevi religiosity in Turkish traditions which traced back to Central Asia, on the one hand, and in medieval Anatolian Sufi orders such as the Yasawi, Bektashi, Qalandari, and Wafa?i, on the other. A new line of scholarship has critiqued the earlier conceptualization of Alevis as “heterodox” as well as the assumption of Central Asian connections. In the meantime, the new scholarship too has focused on medieval Anatolian Sufi orders, especially the Bektashi and Wafa?i, as the fountainhead of Alevi tradition. Critically engaging with both scholarships, this paper argues that it was the Safavid-Qizilbash movement in Anatolia, Azerbaijan, and Iran rather than medieval Sufi orders, that gave birth to Alevi religiosity.  相似文献

Human skeletal remains from the Neolithic sites BHS18 in the interior of the Sharjah Emirate and the Neolithic shell midden UAQ2 (Umm al‐Quwain) on the coast of the Persian Gulf (United Arab Emirates, UAE) were analysed for their isotope ratios of strontium (87Sr/86Sr) and oxygen (18O/16O). The results are not in agreement with earlier assumptions about a Neolithic nomadism between inland regions and the south‐eastern coast of the Persian Gulf. Existing evidence of nomadic movements of the people from BHS18 most possibly refers to transhumance within the mountains in the hinterland. The strontium isotope measurements on human skeletons from UAQ2 on the contrary indicate uninterrupted residence of this population on the coast. Nevertheless, evidence was found of individual mobility between inland regions and the coast.  相似文献

The city of Sumhuram (300 BC–AD 500) is the most important pre‐Islamic settlement in Dhofar, southern Oman. Since the time of its discovery it was evident that its commercial vocation placed it within a complex system of exchange between India and the Mediterranean. Sumhuram was a key site of the kingdom of Hadramawt, built in a place that was geographically strategic to control the most important Indian Ocean trade routes. The importance of the site made the bead assemblage exceptionally rich in materials, technologies used in the production, and provenance. The study of the relationship between materials and shapes, necessary for the creation of a specific typology, has revealed a number of trends. These, in connection with the reference stratigraphy have, in some cases, enabled the identification of differences on a chronological basis. Furthermore, it is possible to detect different uses of materials in different areas of the city. The variety of imported products (raw materials and products) once again underlines the importance of this city‐port in the international maritime trade and its strong connections with India.  相似文献

The lifecycle of a Nabataean and Roman community shrine at Humayma, Jordan reflects the evolving values of the town's inhabitants from the first to the third century CE. This paper reviews the evidence for the shrine's appearance and significance over this period, as well as the nature of the cult practised there. Beginning its existence as a Nabataean shrine, whose design incorporated the rising sun and the town's primary peak, the building was damaged when the Romans converted Nabataea into Provincia Arabia. The Roman garrison initially dismantled the shrine to build their fort, but a few decades later the shrine was restored with a centrally placed Nabataean betyl and legionary altar symbolising harmony between the garrison and the town. The garrison's god, Jupiter‐Ammon‐Serapis, and possibly Isis, were now worshipped alongside the town's Nabataean deity. This shrine stressing military‐civilian harmony was later deliberately damaged, most likely during Zenobia's revolt.  相似文献

We report the first well‐documented case of a South Island site where Mayor Island obsidian is not the dominant source represented. At the Pūrākaunui site (I44/21), located in coastal Otago, we find that most obsidians come from the Taupo Volcanic Zone, including sources near Lake Taupo (52%) and Rotorua (27.7 %). A small proportion of the collection comes from Mayor Island (10.8%) and the Coromandel Peninsula (9.5%) obsidian. The results point to early effects of regionalisation in source exploitation on the South Island.  相似文献

Two Portuguese naus from Vasco da Gama's second voyage to India, left behind to disrupt maritime trade between India and the Red Sea, were wrecked in May 1503 off the north‐eastern coast of Al Hallaniyah Island, Oman. The ships, Esmeralda and São Pedro, had been commanded by da Gama's maternal uncles, Vicente and Brás Sodré, respectively. A detailed study and scientific analysis of an artefact assemblage recovered during archaeological excavations conducted in Al Hallaniyah in 2013 and 2014 confirms the location of an early 16th‐century Portuguese wreck‐site, initially discovered in 1998. Esmeralda is proposed as the probable source of the remaining, un‐salved wreckage.  相似文献

A unique leaded‐gunmetal disc decorated with iconic Portuguese markings was recovered in 2014 during archaeological excavations at the Sodré shipwreck site in Al Hallaniyah, Oman. Initially the identity and function of the disc was unknown, although it did possess characteristics suggesting it could be an astrolabe. Laser imaging of the disc post conservation revealed regular scale marks on the limb of its upper right quadrant. Accurate digital measurements of the marks show them to be graded at close to 5‐degree intervals, thus confirming the identity of the disc as a mariner's astrolabe and the earliest known example discovered to date.  相似文献

“Muslims” and “Dungeons & Dragons” are rarely discussed in the same sentence. However, one of the earliest fantasy role‐playing games, which left a lasting impact on the industry, was the brainchild of Muhammad Abd al‐Rahman (Phillip) Barker (1929‐2012), a professor of South Asian Studies, an expert in Native American languages, and an American convert to Islam. Like Tolkien, Barker created an enormous fantasy world; however, unlike Tolkien, his world was redolent with Native American and South Asian cultural and religious influences. Through this world, he shared with his fans a nuanced understanding of non‐Western societies, cultures, and beliefs – the facets of the human experience that truly constitute multiculturalism. While fictional religion in role‐playing games has been feared and condemned, fictional religion (and occultism) plays a pivotal role in Barker's work; an exploration of his approach towards fictional religion also sheds more light on the question of why fantasy role‐playing games came across as competitors towards religion. Barker's fantasy world brought people of diverse backgrounds together in a beautiful demonstration of how fantasy and science fiction can bring about intercultural and interreligious tolerance in an otherwise intolerant world. Given the centrality of games such as Dungeons & Dragons to American popular culture, an exploration of Barker's legacy can also be seen in the light of the study of the history and contributions of Muslims in America.  相似文献
