For the last 60 years, varnishes of ancient musical instruments, particularly stringed instruments of the violin family dating 17th and 18th centuries, have been analysed to establish their chemical composition and multi-layered structure. The objective was to rediscover the technology for making the varnish of esteemed Italian violins and to reconstitute it. This paper reviews the physico-chemical studies published on such varnishes and also focuses on a research project carried out since 2002 at the Musée de la musique in Paris. It aims to apply in a comprehensive way different non-destructive or micro destructive methods (Py-GC/MS, IR microscopy, SEM/EDX, EDXRF, synchrotron radiation-based techniques, …) to the study of a large and representative number of ancient varnished musical instruments from a museum collection.  相似文献

The paper tries to convey the idea that choosing a winner among a group of nominees or short-listed candidates may hurt those who bestow prizes, those who are selected, as well as those who base their own choices on the ranking. We base our observations on examples of contests (movies, literature, and music) in which winners often turn out not to be better than nominees. Our suggestion is therefore to select, say five candidates, and not to rank them, but reward all nominees equally.  相似文献

This paper presents a deformative and structural study of the Guarneri ‘del Gesù’ violin (1743) known as the ‘Cannone’. A structural assessment is fundamental to understanding the violin's compatibility with its residual function of musical instrument. The tuning of the instrument to a modern playing pitch during concerts could, in fact, cause stress resulting in plastic deformations of its structure. In order to understand the stress level to which the violin is subjected when tuned, several tests were performed. The forces acting on the bridge were measured, the geometry of the un-strung and of the tuned violin were acquired with a tri-dimensional scanner, the violin deformation was assessed by means of the computed surface deviation mesh and by measuring the deformation in selected lines, several sections of the violin were cut from the digital model and stress exerted on the sections was computed. The stress exerted on the neck, scroll and body were found to be very limited. More significant, albeit at a low level, was the stress exerted under the bridge between the sound holes. Mechanical stress exerted after tuning was found to be safe for the violin, if applied for a limited amount of time. This does not mean that the violin can be played freely, because the real strength of the material used in the violin is not known and mechanical stress during a concert must be added to time (viscous behaviour), moisture content variation (mechano-sorptive behaviour) and hygro-thermal stress, thus worsening the condition. The method presented here could be applied to compute the level of stress of any violin.  相似文献

In a parallel study, it has been shown by comparison of successive TV-holography campaigns that murals in the convent of Müstair (Switzerland) have progressively detached from their substrate over a time interval of 5 years (J Cult Herit 2009). Here, we focus on the dynamics of the ongoing detachment processes. In order to regularly measure small surface displacements in situ over a long duration of several years, a new method that we call Mirror Micrometry (MM) has been designed and implemented. This method monitors the reflection of a light beam by a mirror that is mounted to the surface of interest for the duration of the experiment. The mirror is designed to rotate about a pivot as small displacements in the detaching surface occur, thus deflecting the reflected light beam. Measurements over more than three years in the Convent Church and in the Holy Cross Chapel reveal various types of surface displacement perpendicular to the wall surface. These are correlated with relative humidity (RH) changes in the room climate. Reversible short-term variations of approximately ±5–10 μm occur with periods of one to several weeks and relate primarily to weather changes. Reversible long-term variations of ±5–10 μm correspond to averaged seasonal humidity changes. Irregular and irreversible movements in increments of 20–30 μm record very localised progressive detachment steps. A semi-quantitative correlation of approximately 1 μm surface displacement per 1% RH change is calculated. Based on the fact that nearby measuring points can simultaneously move in opposite directions, a geometric model is drawn to explain deformation by hygric swelling and shrinking of different shapes of detached layers.  相似文献

To assess the possible effects of mechanical loading on the conservation of historical wooden musical instruments, a research project was carried out on the violin Guarneri “del Gesù” (1743), known as the “Cannone”. This paper refers to the results obtained by studying the deformations to which a violin is subjected after being tuned, with special attention to the viscous and mechano-sorptive behaviour (as in a concert environment for example). The amount of viscoelastic creep was quantified under normal tuning conditions, and the mechano-sorptive creep was quantified using a dead mass resulting in 55% of the elastic deformation obtained after tuning. The viscoelastic and mechano-sorptive deformations were clearly observed. These deformations were completely recovered once the violin was unloaded, demonstrating that this violin structure is appropriately dimensioned for the applied stresses.  相似文献

The present work was one of the first attempts to analyze the conservation status of two ferrotypes, ancient photographic plates realized on a support made of iron. The photographic material was constituted of collodion as binder for the photosensitive silver halides grains. The two ferrotypes studied belonged to a private collection of a family from Durham, UK, and were made at the end of the 19th century. The analytical techniques used for the morphological and physicochemical characterization were noninvasive. The surface morphology was studied by means of optical microscopy (OM) and environmental scanning electron microscopy (ESEM) coupled with an energy dispersive X-rays (EDX) system for the elemental analysis. These techniques, together with microreflectance Fourier transform infrared spectroscopy (μ-FTIR) and contact angle, allowed to obtain information on both the chemical – elemental – composition of the materials constituting the ferrotypes, and the conservation status of these photographic plates. The study showed that the physicochemical diagnostics allowed to characterize the two ferrotypes that, despite their similar age and provenance, showed different conservation status, surface properties, and elemental composition.  相似文献

This article analyses the economic dimension of a set of activities groupedunder the heading, Culture and Leisure Industry, from three complementaryperspectives: national (Spain), sectoral and regional. Particular emphasis isplaced on determining the value added generated by this industry and itscontribution to the Gross Domestic Product – 4.5% – as wellas showing its level of employment both in absolute terms and as a percentageof the number of employees in the economy – 7.8%. This is apioneer project; studies in this field on either a national or internationalscale are scarce. The study demonstrates that the cultural sector is aproductive activity generating wealth in Spain. However, a high degree ofheterogeneity is found at both the sectoral and regional levels. Economicactivity is led by Performing, Musical and Audiovisual Arts (mainlyTelevision) and Publishing and Printing, which jointly account for about70% of sales and gross value added, and it is concentrated in similarproportions in developed regions specialized in service industries, Madrid andCatalonia, where most culture and leisure activities are available.  相似文献

The oil painting “La Medusa” executed by Caravaggio at the end of the XVI century on a wooden shield, was investigated by integrated physical–chemical and analytical methodologies in order to obtain scientific data capable of elucidating the state of conservation and the painting technique. Optical (OM) and electronic (SEM-EDS) microscopy, micro-FT-IR spectroscopy, gas chromatography–mass spectrometry (GC–MS) and pyrolysis GC–MS were applied on two microfragments and some organic samples obtained by solvent extraction using the swab cleaning technique. The obtained results indicated that Caravaggio probably reused an old shield as a previous gypsum preparation layer has been detected under the original painting layers. He used white lead, natural earths, verdigris and lead–tin yellow type I mixed with drying oils to paint. The considerable amount of amorphous particles of copper chlorides found in the green pigment verdigris suggests that it could have been produced according to the ancient recipe of verde salsum described by Theophilus. Mordant gilding has been identified on the upper part of the shield that can be related to an abandoned experiment to give the painting a mirror-like reflecting effect. Three different varnishes layers have been detected above the painted surface. The original and restoration varnishes have been identified and they contain a mixture of drying oil, mastic and turpentine and some beeswax. Cleaning tests, performed with different organic solvents, suggest the use of isopropyl alcohol as cleaning agent because it is less efficient in comparison to others solvents; thus it ensures a careful and controlled removal of the varnishes.  相似文献

The award of the 1915 Nobel Prize in physics jointly to William Henry Bragg and his elder son, William Lawrence Bragg – `for their services in the analysis of crystal structure by means of Röntgen rays' – seems to have been largely uncontroversial at the time, butthere are a number of questions that surround the award and the events that followed it that deserve exploration. This paper attempts to address these questions.  相似文献

The binding media of the polychromy of Qin Shihuang's Terracotta Army   总被引：2，自引：0，他引：2  
The “Terracotta Army” is a worldwide known archaeological finding in China. It is a part of the burial complex of the emperor Qin Shihuangdi (259–210 BC), which is still under excavation and study. The fact that the sculptures, chariots and weapons of the First Chinese Emperor's Terracotta Army were originally all painted in bright colours is still not widely known. The chemical characterisation of the paint medium was performed through an analytical procedure based on GC-MS. The proteinaceous binder was identified for the first time through a desalting procedure used in proteomics. The identification of egg as a paint binder is extremely interesting in terms of the historical significance of the work of art itself and important in terms of the method of conservation. Moreover it represents one of the first steps towards an understanding of the painting technique used on ancient sculptures in China, of which – despite their fame – nothing is yet known.  相似文献

The coming of new Information CommunicationTechnologies (ICTs) has prompted muchcontroversy in higher education. Scholars andadministrators have been excited by thepotential – perhaps the threat – of the`virtual' university. But whilst much has beenwritten about `virtual higher education', lesshas been said about the actual `work' involved.Drawing upon insights from the sociology oftechnology, this paper reports on the attemptsof one university to reconcile ideas about`virtuality' with the more established networksand infrastructures of traditional universitylife. This research is based upon aparticipant-observation study carried out inthe UK.  相似文献

Along the Umbria-Marche stretch of the Flaminia Consular Road (220 B.C.) several archaeological finds of the most important monumental works, are well preserved. The stones, employed to build many bridges, substructions and sewerages, are represented by carbonatic breccias whose geological environment of formation and source areas had never been established. On the basis of mineralogical, petrographic and micropalaeontological analyses, two groups of these lithotypes employed in Roman age were distinguished: “monogenic carbonatic breccias” only constituted by clasts of the Maiolica Unit (Late Jurassic – Early Cretaceous) and “polygenic carbonatic breccias” made of fragments (in different proportions) of Calcare Massiccio (Early Jurassic), Corniola (Early Jurassic), Maiolica (Late Jurassic – Early Cretaceous) and Scaglia Rossa (Late Cretaceous – Early Paleogene) Units. The possible source areas of the breccias are compatible with stratified slope-waste to scarp-base deposits of periglacial origin belonging to the Upper Pleistocene. In particular, among the seven investigated areas, we pointed out the most probable provenances (Monte Faeto-Colle, Costacciaro, Scirca, Foci, Secchiano) along the flanks of the Apennine Mesozoic chain of the Umbria and Marche regions. Although the Romans could have exploited the whole thickness of some outcrops (now disappeared) of these carbonatic lithotypes at the deepest part of the valleys, we have constrained a local provenance of the breccias so commonly used in the monumental works of the Flaminia.  相似文献

The economic literature on the Eurovision Song Contest (ESC) establishes empirical evidence for culturally biased voting, more precisely also biases based on geographical closeness, political relations, ethnical and linguistic affinity. The Bundesvision Song Contest (BSC), a similar contest with principally the same rules but organized on the national level in Germany, offers a unique opportunity to compare international voting bias patterns to national voting bias patterns. Thus, this paper presents an innovative analysis by comparatively analyzing the ESC’s historical data from 1998 to 2014 and the BSC’s data from its beginning in 2005 until 2014 with the same econometric methodology. Our results show that voting biases do not only matter in international contests but also occur in similarly organized national contests with roughly similar magnitude and quality—despite the cultural background of participants and voters being much more homogenous.  相似文献

This paper investigates the compensation of Court musicians in the late 16thcentury, a period of transitionfrom a medieval feudal system to a market economy. Using data from theTyrolian archives, the paper demonstratesthat one cannot measure the socio-economic status of Court musicians in theHousehold of Archduke Ferdinand IIin Innsbruck only by their wages, but that one must also take intoconsideration all of the financial, material, andnon-material incentives that a Court might provide in the late 16th century.The incentives provided byArchduke Ferdinand's Court in Tyrol constitute a patronage system that isrepresentative of other Courts at the time.  相似文献

Audiences choose to see films using information from previous films. A stochastic consumer choice process based on this assumption generates a particular distribution of financially successful films among film types. Movie stars can be used to mark these successful film types. Thus, their star power originates not only from box-office appeal but also from marking power. Evidence of 960 top 20 films released in the United States and Canada between 1940–1955 and 1960–1995 is consistent with this model.  相似文献
