Seismic Assessment of the Lima Cathedral Bell Towers via Kinematic and Nonlinear Static Pushover Analyses

ABSTRACT

The protection of cultural heritage against earthquake induced actions is one of the main challenges the earthquake engineering science and practice are facing. This article presents a seismic assessment study on one of the most ancient colonial buildings present in Peru, the Cathedral of Lima, focusing on its towers. A historical review highlighted how these structures, together with the whole Cathedral, suffered intense damage and partial collapse during previous earthquakes. In order to identify the structure main deficiencies, both linear kinematic analyses and nonlinear static analyses have been performed. Different nonlinear finite element models have been created to evaluate the influence of the adjacent walls. Different load distributions have been compared to evaluate how simplified patterns could provide results close to load distributions taken from a modal analysis of the complex. A simple retrofit strategy, consisting on the introduction of steel ties, has also been studied as a reference. Results show good correlation between kinematic and pushover analyses. The construction, when compared to the requirements of the national code for new buildings, results significantly vulnerable, pointing out the need to accept some structural damage even after seismic retrofit.     

The manufacturing process of 3rd millennium BC bone based incrusted pottery decoration from the Middle Guadiana river basin (Badajoz,Spain)

The aim of this study is to present the manufacturing process developed on 3rd millennium BC white incrusted pottery from the middle Guadiana River basin (Badajoz, Spain), alongside the analytical procedure developed to determine the nature of these incrustations. The analytical procedure developed in this paper will assess the nature of these incrustations as burnt bone and in fewer cases as calcium carbonate, turning upside down the usual tendency for the Iberian Peninsula, where calcium carbonate has been the only kind of incrustation identified up until now. The analytical facilities used are: SEM-EDX, XRF microprobe, XRD and FTIR. The assessment of the nature of the incrustations as burnt bone has been a hazardous task and it has been necessary to develop a procedure using several analytical techniques and reference materials.     

The Composition of the São Brás Copper Hoard in Relation to the Bell Beaker Metallurgy in the South‐western Iberian Peninsula

A large ceramic vessel was discovered at São Brás (southern Portugal) containing a metallic hoard from the Chalcolithic/Early Bronze Age period. These weapons and tools were characterized by microanalytical techniques as being composed of copper with varying arsenic contents (2.2 ± 1.6 wt%) and minor amounts of lead, bismuth and iron. The collection shows a clear association between daggers and copper with a higher arsenic content, which can be explained by the high status of these silvery alloys. Finally, the compositional distribution of the hoard was compared with the metallurgy of the Bell Beaker and non–Bell Beaker communities inhabiting the south‐western Iberian Peninsula.

The Ciempozuelos Necropolis skull: a case of double trepanation?

The focus of this study is the analysis of a trepanation performed on the skull of an adult male from the famous Bell Beaker necropolis of Ciempozuelos (Madrid) excavated at the end of the 19^th century. The unusual characteristics of the pottery and other associated grave goods gave rise to the use of the name ‘Ciempozuelos’ to define the regional Bell Beaker style; this refers to similar finds from other sites on the Meseta of central Spain. Although trepanations from Chalcolithic contexts in the Iberian peninsula are not infrequent, they are unusual in Bell Beaker inhumations. Furthermore, this skull is exceptional not only for the type of trepanation performed, but also for the subsequent cranial deformation apparently resulting from the operation, as well as evidence of a second subsequent trepanation which indicates a very short post‐surgical survival period for the individual.

Shelley’s Jingling Food for Oblivion: Hybridizing High and Low Styles and Forms

ABSTRACT

This essay argues that there was a sense in which Shelley actively approved of “jingling verse.” His poetic energy was sustained by a substratum of popular and tuneful versifying, such as impromptus, bouts-rimés, anagrams, enigmas, ballads, Mother Goose rhymes, proverbs, hymns, and drinking songs. He hybridizes the registers and meters of these humble forms with elevated, sublime, and erudite ones. This hybridization is, arguably, connected to the characteristic coexistence of the direct and clear with the knotty and puzzling in his poetry. After a brief account of Shelley’s submerged youthful reading, noting in passing that Shelley’s lyrics proved amenable during the early twentieth century to recycling as Shelleyesque jingles, the essay illustrates its thesis from unfamiliar fragments in Shelley’s notebooks, such as the late lyric fragment “Time is flying,” and from more familiar matter such as “Dirge for the Year,” “Mont Blanc,” “The Cloud,” “On the Medusa of Leonardo da Vinci,” “The Sensitive Plant,” “Song: to the Men of England,” “Ode to the West Wind,” and Peter Bell the Third.

Andrew Dury's map of the present seat of war,between the Russians,Poles, and Turks (1769)

Abstract

The chance assembling of a number of different impressions of Andrew Dury's Map of the present Seat of War between the Russians, Poles, and Turks (1769) in the British Library led the authors to examine the map's carto‐bibliographical history. Nine states of the map, two of which were sometimes sold with printed paste‐ons, have been identified to date. The two earliest states of the map are now in the State Historical Museum, Moscow. Although both are best described as proof, or pre‐publication, impressions, each bears evidence of intensive use at the highest levels of the Russian army command. Indeed, the circumstances leading to the creation of the map by Andrew Dury and Peter Bell and to a succession of different versions over the three decades or so of intermittent Russian‐Turkish hostilities highlight the interplay of international politics, individual initiative and commercial factors in late eighteenth‐century map production in London.     

The Primacy of Science in Modernity,of Technology in Postmodernity,and of Ideology in the History of Technology

The abrupt reversal of culturally ascribed primacy in the science–technology relationship—namely, from the primacy of science relative to technology prior to circa 1980, to the primacy of technology relative to science since about that date—is proposed as a demarcator of postmodernity from modernity: modernity is when ‘science’ could, and often did, denote technology too; postmodernity is when science is subsumed under technology. In support of that demarcation criterion, I evidence the breadth and strength of modernity’s presupposition of the primacy of science to and for technology by showing its preposterous hold upon social theorists—Marx, Veblen, Dewey—whose principles logically required the reverse, viz. the primacy of practice; upon 19th and 20th century engineers and industrialists, social actors whose practical interests likewise required the reverse; and upon the principal theorizers in the 1970s of the role of science in late 20th century technology and society. The reversal in primacy between science and technology ca 1980 came too unexpectedly, too quickly, and, above all, too unreflectively to have resulted from the weight of evidence or the force of logic. Rather, it was a concomitant of the onset of postmodernity. Oddly, historians of technology have remained almost wholly unacknowledging of postmodernity’s epochal elevation of the cultural standing of the subject of their studies, and, specifically, have ignored technology’s elevation relative to science. This I attribute to the ideological character of that discipline, and, specifically, to its strategy of ignoration of science.     

How was Bell Beaker economy related to Corded Ware and Early Bronze Age lifestyles? Archaeological,botanical and palynological evidence from the Hegau,Western Lake Constance region

Abstract

The Europe wide spread of what has been called the Bell Beaker phenomenon remains an enigma of European prehistory. While most of the recent research stresses the ideological aspects of using Bell Beaker material culture, here we take a regional and economical perspective. We look for the chronological relationships and the economic choices of the Bell Beaker phase and of its closest neighbours in time and space: the Late Neolithic Corded Ware and the Early Bronze Age. We focus on the regional archaeological settlement history and present the hitherto richest European Bell Beaker-associated collection of palaeobotanical macro-remains, together with our high-resolution palynological work on annually laminated lake sediments. These different lines of evidence are tied together by an absolute chronology derived from new radiocarbon accelerated mass spectrometry (AMS) dates (now more than 200) and from the dendrodates from the World Heritage wet preserved pile dwellings. We show the preceding Late Neolithic, the actual Bell Beaker, and the following Early Bronze age economies each relying on different agricultural strategies that focus on distinct parts of the landscape. There is no link obvious between Late Neolithic and Bell Beaker, but there is between Bell Beaker and Early Bronze Age. Related to different modes of production, differences in ideology become visible in food preferences as well as in other parts of the material culture. We conclude that the Bell Beaker economy represents a re-orientation of the mode of production focusing on single, rather small farmsteads which often do not leave a distinct signal in the archaeological record.
