The Roman wreck found off Grado, not far from the city of Aquileia in the north Adriatic Sea, was recovered in 1999. The ship carried various kinds of amphoras with processed fish. A lead pipe, inserted in the hull near the keel, is curious evidence which the authors try to explain. The pipe could be connected to a piston‐pump to suck water. A theoretical reconstruction demonstrates how this apparatus could work and that it could be used to feed a tank to allow trading in live fish over a long distance. © 2011 The Authors  相似文献

This article presents a study on welded beam-to-column joints of moment-resisting steel frames. The main features of the joint specimens are summarised, in order to identify key parameters influencing the joint response as well as their low-cycle fatigue endurance. The cyclic behavior and the low-cycle fatigue strength of the connections were initially assessed by cyclic quasi-static testing, carried out at the Technical University of Milan. Analysis of the results has been carried out in order to verify the validity of a linear damage accumulation model combined with a low-cycle fatigue approach based on S-N lines concept. Moreover, a criterion to predict the type of failure and a procedure of appraising the fatigue endurance are presented and their validity proved by the results of variable amplitude tests.  相似文献

Fragments of Roman sewn‐plank boats have been found, during rescue excavations, in the Canale Anfora, an artificial channel used by Roman ships to enter the Roman city of Aquileia. Remains were found in both 1988 and 2005 at the same site. Elements of what were probably two boats are analysed and compared to other finds of Roman sewn boats found along the coast of the Veneto and Friuli Venezia Giulia regions. They are evidence of the use of this technique, instead of the more widespread mortise‐and‐tenon system, in the quite limited area of the Northern Adriatic. These boats were used both for inland and for maritime navigation.  相似文献

This article tackles the issue of literary censorship in Fascist Italy. The first part offers an outline of the organization and the practices with which the regime attempted to control publishers and authors. It tracks the development of Mussolini's Press Office into a fully fledged ministry, examines the introduction of a semi-preventive form of censorship, and looks at the effects of the anti-Semitic laws. The second part concentrates on the literary activities of the novelist, editor and translator, Elio Vittorini. His many encounters with Fascist censorship provide ideal subject matter for a close examination of how censorship affected literary production. It also provides an example of the need to re-address aspects of Italy's literary history during the Fascist period, particularly in relation to questions of coercive and consensual collaboration with the regime.  相似文献

This essay surveys the main reforms carried out by the Habsburg governments in Lombardy and Tuscany from the 1730s to around 1790 in the light of recent historical literature. Venturi's biographical approach to the theme is discussed in the first part of the essay, which then sets out to compare reforming activities in the two states in the fields of the administration of justice, ecclesiastical policy, and public finance. The drive towards centralization and uniformity is identified as the main aspect of the Milan reform movement, to the liberal and humanitarian tendencies of Peter Leopold's government in Tuscany.  相似文献

In the early years of the atomic era, several developing countries attempted to establish a nuclear programme, yet Brazil's case is less well-known. As new documents show, from 1951 Brazil aimed to acquire the nuclear fuel cycle capability in spite of legislation imposed by the United States to limit the emergence of new nuclear powers. This article will analyse the origins of the Brazilian nuclear programme from 1951 to 1955 and will explore its cooperation in the atomic field with international partners.  相似文献

The sequence of earthquakes that has affected Christchurch and Canterbury since September 2010 has caused damage to a great number of buildings of all construction types. Following post-event damage surveys performed between April 2011 and June 2011, an inventory of the stone masonry buildings in Christchurch and surrounding areas was carried out in order to assemble a database containing the characteristic features of the building stock, as a basis for studying the vulnerability factors that might have influenced the seismic performance of the stone masonry building stock during the Canterbury earthquake sequence. The damage suffered by unreinforced stone masonry buildings is reported and different types of observed failures are described using a specific survey procedure currently in use in Italy. The observed performance of seismic retrofit interventions applied to stone masonry buildings is also described, as an understanding of the seismic response of these interventions is of fundamental importance for assessing the utility of such strengthening techniques when applied to unreinforced stone masonry structures.  相似文献
