Long-term clay raw material selection and use in the region of Classical/Hellenistic to Early Byzantine Sagalassos (SW Turkey)

A provenance study was carried out on coarse ceramics from the Classical/Hellenistic to Mid-Byzantine city of Sagalassos, SW Turkey. The ceramics were sampled from the excavations of the city, and clay raw materials were sampled throughout its ancient territory. Used techniques were optical microscopy and electron microprobe analysis on thin sections, geochemical analysis (fusion ICP/MS and mineralogical analysis (X-ray diffraction). The geochemical/mineralogical diversity in the ceramics is not as wide as for the clay raw materials. It seems that even at the restricted scale of this study, the resources were limited to the area around the ancient site. The differences between the ceramics are likely due to the use of different ophiolitic clay bodies being exploited for their production.     

Hermann Oppenheim's observations about music in aphasia

Hermann Oppenheim was influential in many areas of neurology, but his ideas about music are relatively unknown. In 1888, he published a paper that outlined how the assessment of music skills in patients with aphasia could lead to a better understanding of aphasia and language. Oppenheim conducted the first comprehensive music assessment as part of a neurologic examination and presented the first case series of music in aphasia. His paper was widely cited and had significant influence over the next 30 years. Although largely unrecognized as such, Oppenheim was an important historical figure in the study of music and neurology.     

Neutron tomography for the assessment of consolidant impregnation efficiency in Portuguese glazed tiles (16th and 18th centuries)

Neutron tomography (NT) has been applied to visualize the inner structure of ancient Portuguese glazed tiles undergoing conservation treatments. Neutrons have the advantage of interacting strongly with hydrogen, so NT is able to map hydrogenous compounds with high sensitivity. The present study explores its potential for assessing the distribution of the consolidant Paraloid B-72 inside tiles, to evaluate the efficiency of two different methods of treatment: brushing and immersion in solution. Using a prototype NT setup at the Reactor Português de Investigação (Sacavém, Portugal), each two-dimensional image is obtained from a 90 s exposure, at a thermal neutron flux of 2 × 10⁵ n cm⁻² s⁻¹ at the irradiation site. The neutron beam has a diameter of 5 cm, so fragments with outer dimensions up to 4.8 cm can be inspected. Samples are automatically rotated by an angle of 0.9° between successive images. Images were obtained before and after the application of the consolidant. The results obtained show that: (i) NT is a useful tool for visualization of the inner structure of ancient glazed tiles, and to assess penetration depth of consolidant and its distribution inside the tile; and (ii) brushing with 10% Paraloid^® B-72 in acetone solution appears to be more efficient than immersion. Neutron tomography showed a greater and more uniform retention of resin inside the tile if the brush is used to apply the consolidant, to increase the cohesion of the object.     

SHAPE MEMORY ALLOYS IN SEISMIC RESISTANT DESIGN AND RETROFIT: A CRITICAL REVIEW OF THEIR POTENTIAL AND LIMITATIONS

Shape memory alloys (SMAs) are a class of materials that have unique properties, including Young's modulus-temperature relations, shape memory effects, superelastic effects, and high damping characteristics. These unique properties, which have led to numerous applications in the biomedical and aerospace industries, are currently being evaluated for applications in the area of seismic resistant design and retrofit. This paper provides a critical review of the state-of-the-art in the use of shape memory alloys for applications in seismic resistant design. The paper reviews the general characteristics of shape memory alloys and highlights the factors affecting their properties. A review of current studies show that the superelastic and high-damping characteristics of SMAs result in applications in bridges and buildings that show significant promise. The barriers to the expanded use of SMAs include the high cost, lack of clear understanding of thermo-mechanical processing, dependency of properties on temperature, and difficulty in machining.     

SEISMIC WAVE ATTENUATION FOR VRANCEA EVENTS REVISITED

New aspects of the frequency-dependent attenuation of the seismic waves travelling from Vrancea subcrustal sources toward NW (Transylvanian Basin) and SE (Romanian Plain) are evidenced by the recent experimental data made available by the CALIXTO'99 tomography experiment. The observations validate the previous theoretical computations performed for the assessment, by means of a deterministic approach, of the seismic hazard in Romania. They reveal an essential aspect of the seismic ground motion attenuation that has important implications on the probabilistic assessment of seismic hazard from Vrancea intermediate-depth earthquakes. The attenuation toward NW is shown to be a much stronger frequency-dependent effect than the attenuation toward SE and the seismic hazard computed by the deterministic approach fits satisfactorily well the observed ground motion distribution in the low-frequency band (<1Hz). The apparent contradiction with the historically-based intensity maps arises mainly from a systematic difference in the eigenperiods (type and size) of the buildings in the intra- and extra-Carpathians regions, thus the existing macroseismic data, based on buildings of small dimensions, i.e. with high eigenfrequency (5–10 Hz), can hardly be representative of the real hazard for new and large dimension, tall buildings, with eigenfrequency above 1 Hz.     

Experimental Dynamic Behavior of Free-Standing Multi-Block Structures Under Seismic Loadings

This article describes the dynamical behavior of free-standing block structures under seismic loading. A comprehensive experimental investigation has been carried out to study the rocking response of four single blocks of different geometry and associations of two and three blocks. The blocks, which are large stones of high strength blue granite, were subjected to free vibration, and harmonic and random motions of the base. In total, 379 tests on a shaking table were carried out in order to address the issues of repeatability of the results and stability of the rocking motion response. Significant understanding of the rocking motion mechanism is possible from the high quality experimental data. Extensive experimental measurements allowed to discuss the impulsive forces acting in the blocks and the three-dimensional effects presented in the response.     

Changing places: investigating the cultural terrain of village pubs in south Northamptonshire

The village pub has traditionally held an important ‘place’ in British economy and society and as such is an interesting site for social and cultural analysis. At one level, it is a site with pronounced mythic qualities. Yet on another level, the place of the village pub is highly unstable and contested, with many reportedly facing closure. Adopting an avowedly ‘production-centred’ approach, this paper presents exploratory survey findings from two case study villages in south Northamptonshire. This includes an examination of each pub's input supply network, including links with brewers and other suppliers. The paper attempts to move beyond viewing the village pub simply as a declining rural service and focuses in particular on the ways in which pubs commodify ‘local culture’ as an economic resource. It concludes by introducing the concept of ‘cultural terrain’ and its application to the study of village pubs and rural services more generally.

Changement de décor: examiner le champ culturel des pubs de village dans le sud du Northamptonshire

Le pub de village a conservé depuis longtemps une «place» importante dans l'économie et la société de l'Angleterre. Il est un lieu qui présente un grand intérêt pour analyser les dimensions sociales et culturelles. Le pub de village est d'emblée un lieu ayant acquis d'importantes qualités mythiques, mais occupe à un autre niveau une place très instable et contestée. Selon les informations disponibles, plusieurs auraient déclaré faillite. Partant d'une approche ouvertement «centrée sur la production», cet article présente des conclusions d'une étude de cas exploratoire réalisée sur deux villages dans le sud du Northamptonshire. Il est proposé un examen du réseau d'approvisionnement de chaque pub, y compris les partenariats avec les brasseurs et fournisseurs. L'article tente de dépasser l'idée que le pub de village est un service rural en voie de disparition. Il porte principalement sur les façons dont les pubs commercialise la «culture locale» pour en faire une ressource économique. L'article se termine par un survol de la notion de «champ culturel» et de son application dans la présente étude sur les pubs de village et les services ruraux en général.

Cambiar de lugar: una investigación del terreno cultural de los bares de pueblos en el sur de Northamptonshire

Tradicionalmente el bar de un pueblo ha ocupado un lugar importante en la economía y la sociedad británicas y por eso es un sitio interesante donde hacer análisis social y cultural. A un nivel es un sitio de cualidades míticas pero a otro nivel el lugar del bar del pueblo es muy inestable, ya que muchos corren el peligro de que los cierren. Con un enfoque centrado en la producción, este papel presenta los resultados de estudios preliminares realizados en dos pueblos del sur de Northamptonshire. Incluye un examen de la red de proveedores de cada bar, incluyendo los vínculos con cervecerías y otros proveedores. El papel pretende ir más allá de la idea que hay del bar del pueblo como un servicio rural en declive y se centra en particular en las maneras en que los bares hacen mercancía de ‘la cultura local’ como recurso económico. Concluye por introducir el concepto de ‘terreno cultural’ y la aplicación de ello al estudio de los bares de pueblos y servicios en zonas rurales en general.     

De Bow’s Revolution: The Memory of the American Revolution in the Politics of the Sectional Crisis, 1850–1861

In January 1861 editor James D.B. De Bow advocated the secession of southern states from the union as he proclaimed to his readers that white Southerners “are mainly the descendants of those who fought the battles of the Revolution, and who understand and appreciate the nature and inestimable value of the liberty which it brought.” While editors on both sides of the Sectional Crisis over slavery in the 1850s and 60s claimed to be “custodians of the legacy of 1776” as they used the American Revolution symbolically in their rhetoric. By focusing on De Bow’s Review, a widely read and influential journal during this fight, we can gain a better understanding of the specific terms by which Southerners were encouraged to think of themselves not as rebels but as guardians of “the true American character.”
