Tortoiseshell or Polymer? Spectroscopic Analysis to Redefine a Purported Tortoiseshell Box with Gold Decorations as a Plastic Box with Brass

The study and preservation of museum collections requires complete knowledge and understanding of constituent materials that can be natural, synthetic, or semi-synthetic polymers. In former times, objects were incorporated in museum collections and classified solely by their appearance. New studies, prompted by severe degradation processes or conservation-restoration actions, help shed light on the materiality of objects that can contradict the original information or assumptions. The selected case study presented here is of a box dating from the beginning of the 20th century that belongs to the Portuguese National Ancient Art Museum. Museum curators classified it as a tortoiseshell box decorated with gold applications solely on the basis of visual inspection and the information provided by the donor. This box has visible signs of degradation with white veils, initially assumed to be the result of biological degradation of a proteinaceous matrix. This paper presents the methodological rationale behind this study and proposes a totally non-invasive methodology for the identification of polymeric materials in museum artifacts. The analysis of surface leachates using 1H and 13C nuclear magnetic resonance (NMR) complemented by in situ attenuated total reflection infrared spectroscopy (ATR FT-IR) allowed for full characterization of the object s substratum. The NMR technique unequivocally identified a great number of additives and ATR FT-IR provided information about the polymer structure and while also confirming the presence of additives. The pressure applied during ATR FT-IR spectroscopy did not cause any physical change in the structure of the material at the level of the surface (e.g., color, texture, brightness, etc.). In this study, variable pressure scanning electron microscopy (VP-SEM-EDS) was also used to obtain the elemental composition of the metallic decorations. Additionally, microbiologic and enzymatic assays were performed in order to identify the possible biofilm composition and understand the role of microorganisms in the biodeterioration process. Using these methodologies, the box was correctly identified as being made of cellulose acetate plastic with brass decorations and the white film was identified as being composed mainly of polymer exudates, namely sulphonamides and triphenyl phosphate.

Price linkages in the copper futures, primary, and scrap markets

This study investigates how markets for different levels of copper purity are interrelated by testing the long-run price linkage and causalities among the copper futures, primary, copper scrap, and brass scrap markets. It is expected that copper markets that deal with high purity levels, such as the futures, primary, and copper scrap markets, have a long-run relationship. However, brass scrap markets where copper with a lower purity is traded may not have a price linkage with other copper markets. The results reveal that a long-run relationship holds between the futures, primary, and copper scrap markets but the brass scrap market does not have a long-run relationship with the other markets. From the short-run and long-run causality tests, we determine that the futures market plays an important role in transmitting price information to other copper markets while such information flow is not found for the brass scrap market.

The story of … the military jacket

Fashion and war don’t seem an obvious pairing, but the military jacket is a fashion staple. It may take the form of a double-breasted dress uniform with brass buttons and epaulettes, trimmed in rock star braid, or it may be a khaki combat jacket, worn with Doc Martens and a scowl. Here I explore how these two forms of the military jacket were frogmarched into fashion...

Mechanism of improvement in oil spreadability of aluminium alloy-graphite particle composites

The spreadability of SAE-30 oil on Al-12 Si base (LM-13) alloy containing dispersed graphite particles about 50 μm average size in its matrix is found to be greater than on either LM-13 with no graphite or brass. It is also found that the spreadability on LM-13 base alloys increase with increasing volume of graphite dispersion in the matrix of these alloys. Further increases in the spreadability of oil on machined LM-13-graphite particle composite test surfaces occur if these are rubbed initially against control discs of either LM-13 or grey cast iron. The formation of a triboinduced graphite-rich layer, confirmed by esca, appears to be responsible for the improved oil spreadability on the rubbed test surfaces of LM-13 base alloys as compared to the as-machined test surfaces prior to rubbing. The triboinduced layer of graphite is apparently responsible for the observed reduction in the friction, wear and seizing tendency of triboelements made from aluminium alloy-graphite particle composites.

Thermal gap conductance at low contact pressures (<1 MPa): Effect of gold plating and plating thickness

Thermal contact conductance (TCC) measurements are made on bare and gold plated (<= 0.5 mu m) oxygen free high conductivity (OFHC) Cu and brass contacts in vacuum, nitrogen, and argon environments. It is observed that the TCC in gaseous environment is significantly higher than that in vacuum due to the enhanced thermal gap conductance. It is found that for a given contact load and gas pressure, the thermal gap conductance for bare OFHC Cu contacts is higher than that for gold plated contacts. It is due to the difference in the molecular weights of copper and gold, which influences the exchange of kinetic energy between the gas molecules and contact surfaces. Furthermore, the gap conductance is found to increase with increasing thickness of gold plating. Topography measurements and scanning electron microscopy (SEM) analysis of contact surfaces revealed that surfaces become smoother with increasing gold plating thickness, thus resulting in smaller gaps and consequently higher gap conductance.

Ühis- ning erijooni Soome ja Eesti Kaitseliitude puhkpillimuusikas aastatel 1925-1934.

This study focuses on the similarities and differences between the Estonian Defence League and the Finnish Civil Guard brass bands during the period 1925-1934. By 1934 this paramilitary volunteer state defence organisation had reached stability in its development, such that social, cultural and patriotic education of the people - with the help of brass band music among other means- had acquired a significant role, in addition to prioritised military and sports activities. The study begins with introductory paragraphs I and II, which describes the founding of the organisations, their participation in the Wars of Independence and their subsequent peace time activities as well as their representation in the media at the time. The thesis also briefly introduces military music in Finland and Estonia, as well as describes the influence of military music on the Defence League brass bands. The period under review includes the global economic crisis, which undoubtedly concerned the Defence League/Civil Guard and the Lapua and War of Independence movements, which greatly affected the apolitical principles of the organisations. The main emphasis of the thesis is the Defence League/Civil Guard brass band`s musical activities in two counties - Etelä-Pohjanmaa and Pärnumaa, while also including a general overview of the Estonian Defence League brass bands´ activities. One of the most important benefits of the thesis is its introduction of the brass band repertoire in use at the time, which was played by both professional and as well as amateur orchestras the latter of which also included the brass bands of the Defence League/Civil Guard and the Fire Services. Brass band music held a secondary, yet significant position in the Defence League/Civil Guard, where the orchestra as a musical grouping was obliged to perform not only at inner-organisational and national celebrations but also at any event requiring brass band music, such as song festivals, singing days, and other local cultural events. The professional preparation of the band conductors at the beginning of the period under review was not well specialised, but the training of the Defence League/Civil Defence brass band conductors was carried out regularly in both republic according to the opportunities and dedicated training programmes available. The musicians of the Defence League/Civil Defence brass bands were at the same time members of the military organisations as well as amateur musicians, which placed upon them extra demands - they were under close public supervision in all situations. Based on the principle of chronology it appeared that both Finnish and Estonian respective organisations´ brass bands used the gradually improving economic situation for purchasing musical instruments, obtaining repertoire and training musicians/conductors. Despite the fact that brass band music in the Defence League/Civil Guard was considered an amateur activity and a hobby, the more far-reaching objective of the organisation was to resemble the Defence Forces´ orchestras as closely as possible in all aspects. The Defence League/Civil Guard brass band music definitely had a significant influence on forming, developing and enriching music life in both republics. The reviewed nine-year period introduced the musical activities of the Defence League/Civil Guard against the background of the everyday life of the organisation and the need for brass band music and its continuity in the voluntary state defence institutions of both republics.

Evolution of and preconditions for generation of corrugations on a plane surface in rolling contact

A hard roller under normal load is driven by the flat surface of a soft disc. Corrugations are generated on the disc when certain surface morphological, load, speed and mechanical property-oriented conditions are met. The evolutionary process of corrugation generation and the preconditions necessary for it are investigated morphologically and mechanically for four disc materials: mild steel, brass, PTFE and PMMA.

Microstructure and texture evolution during accumulative roll bonding of aluminium alloys AA2219/AA5086 composite laminates

Accumulative roll bonding of two aluminium alloys, AA2219 and AA5086 was carried out up to 8 passes. During the course of ARB, the deformation inhomogeneity between the two alloy layers results in interfacial instability after the 4th pass, necking of the AA5086 layers after the 6th pass and fracture along the necked regions after the 7th and 8th pass. The EBSD analysis shows deformation bands along the interfaces after 8 passes of ARB. The ARB-processed materials predominantly show characteristic deformation texture components. The weak texture after the 2nd pass results from the combination of a weakly-textured starting AA2219 layer and a strongly-textured starting AA5086 layer. A strong deformation texture forms due to the high imposed strain after a higher number of ARB passes. Subgrain formation and related shear banding induces copper/S components in the case of the small elongated grains, while planar slip leads to the formation of brass component in the large elongated grains.

Development of microstructure and texture in Copper during warm accumulative roll bonding

The evolution of microstructure and texture gradient in warm Accumulative Roll Bonded Cu-Cu multilayer has been studied. Grain size distribution is multimodal and exhibits variation from middle to surface layer. Evolution of texture is largely influenced by shear, in addition to rolling deformation. This leads to the formation of a texture comprising of high fraction of Brass and rolling direction-rotated cube components. Partial recrystallization was observed. Deformed and recrystallized grains were separated using a partition scheme based on grain orientation spread and textures were analyzed for both the partition. Retention of deformation texture components in recrystallized grains suggests the mechanism of recrystallization as continuous recrystallization. Shear deformation plays an important role in grain refinement through continuous recrystallization. (C) 2012 Elsevier Inc. All rights reserved.
