据《三国志·魏书》记载,魏明帝死于景初三年,少帝继位后,仍称当年为景初三年,但次年则改称正始元年。"景初四年"的年号实际上并不存在。日本出土的三角缘盘龙镜为东渡的中国工匠在日本制作,因不能及时得知中国魏朝皇帝改年号之事,所以在铜镜的铭文中使用了"景初四年"的年号。  相似文献

This paper investigates directional influences in the distribution of Bronze Age surface pottery in the northern Murghab Delta, Turkmenistan. Drawing upon a continuous dataset of pottery sherd counts obtained by intensive field survey, it examines the degree to which we can make sense of the archaeological processes at work in a heavily obstructed and dynamic landscape. In so doing, it makes use of two analytical methods that have rarely been used in archaeology: a) geostatistical analysis using variograms to investigate directional spatial autocorrelation in recorded sherd counts; and b) angular wavelet analysis in evaluating directional influences in the sherd distributions for particular chronological periods. While some kinds of directional influence can be identified visually, a quantitative approach is particularly useful in deconstructing such patterns. In this particular dataset, distinct but related directional processes can be identified and measured: a) the impact of the complex system of watercourses in the delta on both settlement and post-depositional processes; and b) recovery bias in the observations made during survey.  相似文献

The Järrestad rock carving site in SE Sweden from the Bronze Age is examined as to the orientation of the individual carvings. A very strict orientation with respect to the main stages in the annual rhythm of the Sun is recorded; 60 feet, 61 shoes and a leading dancer all face the sunrise at Winter solstice, 20 ships face the sunset at Winter solstice, 12 feet point to the sunset at Summer solstice, and one serpent wiggles towards the sunrise at Summer solstice. Obviously, the Bronze Age people kept a strict control of the Sun's annual motions. The sunrise at Winter solstice seems to have been especially important.  相似文献

The author got a chance to visit Turkey for investigating the damage of industrial facilities in the 1999 Kocaeli Earthquake which occurred on 17 August 1999 in the Kocaeli province of Turkey.

This report provides a brief investigation obtained through the seismic damage survey, particularly, focused on the damages to industrial facilities. The epicentral area in the Kocaeli province is the most industrial region of Turkey. Severe excitation attacked this region and industrial plants and structures were more or less damaged. Since the author could only visit a few sites, the report mainly describes the damages of two plants; TÜPRA? oil refinery where big fire occurred and TOYOTA-SA car manufacturing factory where no significant damage appeared.  相似文献

Abstract

We present the analyses of plant macroremains from Iritegi, a cave from Northern Iberia with archaeological levels dated from the Chalcolithic to the Iron Age. Wood charcoal assemblages are dominated throughout the sequence by Fraxinus. Other important taxa are Quercus subg. Quercus, followed by Corylus avellana, Fagus sylvatica, Ilex aquifolium, Taxus baccata and Ulmus. Acer, Alnus and Maloideae occur in very low numbers. The high percentages of Fraxinus are possibly result from the selection of ash for fodder. Evidence for the use of crops (Hordeum vulgare, Triticum aestivum/durum) comes only from the Chalcolithic contexts. The identification of acorns in one Chalcolithic hearth shows that roasting of these nuts was taking place maybe to improve taste and to facilitate further processing or to improve storage conditions. The results show that plant food gathering still played a role within the subsistence of farming human groups in the region.  相似文献

A senior Japanese authority on the Russian economy and its energy sector addresses the country's exposure to the so-called Dutch disease, suggesting that Russia did suffer from the potentially ruinous overdependence on oil and gas exports. The author argues, however, that the symptoms of the disease were actually not severe, attributing his interpretation to: (1) drastic decline of noncompetitive domestic manufacturing industries in the 1990s, which prompted a huge inflow of imports in the 2000s, but left competitive manufacturing enterprises in a position to survive; (2) extraordinary oil price increases in the 2000s, which significantly raised household and business incomes, creating augmented demand for products of domestic origin; (3) large differences between Russian and world prices of oil and gas, which functioned as subsidies for domestic manufacturing; and (4) massive intervention in foreign exchange markets by the Central Bank of Russia, which restricted the growth of imports and thus strengthened the surviving domestic manufacturing enterprises.  相似文献

This paper explores the incongruous relationship between bone raw material availability and technological choice at the Early Bronze Age site of Horvat 'Illin Tahtit (HIT) in central Israel. At HIT, the worked bone assemblage is mostly comprised of minimally modified sheep and goat metapodia whose function(s) are enigmatic. Most specimens have longitudinally oriented scraping abrasions on at least one face, and of these, some have bilaterally symmetrical drilled perforations on the distal–posterior face. Furthermore, the distal epiphyseal plates of almost all worked metapodia are unfused, whereas unfused epiphyses are nearly absent from the general faunal assemblage. Worked goat metacarpals are significantly more common than sheep metacarpals or metatarsals of either species, despite the greater abundance of sheep over goat in the general faunal assemblage. This paper proposes that the desire to express specific visible attributes of the bone raw material was the key motivation in choosing unfused goat metacarpals over similar, more abundant choices. The analysis considers material properties such as bone mineral density and natural morphology and concludes that material properties between various choices were equivocal. This result suggests that social meanings attributed to specific animals and specific skeletal elements structured bone raw material procurement decisions.

The Belgammel Ram was found off the coast of Libya in 1964, and examined during 2008–9. The following techniques were used: surface non‐contact digitizing using a laser scanner, reflectance transformation imaging using polynomial texture mapping and hemi‐spherical harmonics, digital photogrammetry with dense surface modelling, structured light optical scanning, and X‐ray fluorescence analysis. For internal structure the ram was examined by X‐radiography and 3‐D X‐ray tomography. Metallurgical composition was studied by micro‐drilling and subjecting the samples to scanning electron microscope X‐ray micro‐analysis, micro X‐ray fluorescence and X‐ray backscatter. The lead isotope composition was analysed. The alloy has average percentage composition Cu = 86.9, Sn = 6.3, Pb = 6.6, and Zn = < 0.10. The Belgammel Ram is probably a Hellenistic‐Roman proembolion from a small military vessel or tesseraria. The archived data are at the Faculty of Engineering and Environment, Engineering Sciences, Material Data Centre, University of Southampton ( muvis@soton.ac.uk ).  相似文献

This article presents a case study of the rise of Pfizer as a leading pharmaceutical company, with a focus on changing relationships between manufacturing technology and R&D between the mid 1940s and the mid 1960s. Pfizer first moved into pharmaceuticals through participation in the US government's penicillin effort during World War II. The company had expertise in deep tank, biological fermentation for the production of chemicals that it adapted to the manufacture of penicillin. Having greatly expanded its biological manufacturing capacity to meet state needs, Pfizer adopted an R&D program to find new microbial antibiotics suited to its manufacturing technology after the war ended. Pfizer's successes in this antibiotic era established the firm as a major pharmaceutical company. In looking to larger commercial markets for drugs, Pfizer, like its competitors, pursued medicines for chronic diseases rather than acute infections. For this pursuit, in the 1950s and 1960s, Pfizer transformed itself into a chemistry‐orientated pharmaceutical firm by reorienting its R&D toward chemistry. This led to a growing divergence between R&D and manufacturing and the eventual replacement of biological manufacturing with chemical manufacturing. The article explores the changing trajectories of R&D and manufacturing at Pfizer, their shifting positions within the firm, and the consequences of these changes and shifts for the firm's strategy and organization.  相似文献

This paper presents the results of three seasons of investigations in the western part of Ja'alan in the southern al‐Sharqyiah Governorate in the Sultanate of Oman. The results highlight the importance of this part of Ja'alan during the Early Bronze Age (EBA), particularly the Hafit period and provide us with important information about the funerary archaeological landscape during this period. The results also reveal important aspects of landscape utilisation and occupation during this time and add to our knowledge of the cultural and economic facets of the earliest Bronze Age societies. The distribution of tombs in the landscape suggests that they were constructed by nomadic or semi‐nomadic pastoral groups that shifted from one location to another in search of grazing for their livestock. The availability and seasonality of natural resources such as water, pasture and game made it necessary for them to mark their tribal territory with their funerary structures.  相似文献
