Halloysite Nanotubes for Cleaning, Consolidation and Protection
2017
Herein, we report our recent research concerning the development of halloysite based protocols for cleaning, consolidation and protection purposes. Surface modification of halloysite cavity by anionic surfactants was explored to fabricate inorganic micelles able to solubilize hydrophobic contaminants. Hybrid dispersions based on halloysite and ecocompatible polymers were tested as consolidants for paper and waterlogged archaeological woods. Encapsulation of deacidifying and flame retardant agents within the halloysite lumen was conducted with aim to obtain nanofiller with a long-term protection ability. The results prove the suitability and versatility of halloysite nanotubes, which are per…
Nanoclays for Conservation
2019
Within the conservation of artworks materials, this chapter describes innovative strategies based on clay nanoparticles that are promising for protective coating, surface cleaning, and consolidation. We present the preparation of polymer/montmorillonite nanocomposites, which are revealed as efficient protective coatings for highly porous stones, marbles, and bread-made artifacts. Anticorrosive films for metal substrates have been obtained by polymer filling with laponite and halloysite nanotubes (HNTs) containing corrosion inhibitors into their lumen. The dispersion of hydrophobically modified HNTs into chitosan matrix drives to fabricate biofilms with surface cleaning capacity. Rust stains…
Restoration of a polymateric sculpture of the immaculate conception
2016
This study focuses on the intervention methodologies applied on a polymateric polychrome sculpture of the Immaculate Conception (18th century), located inside the chapel of the Oratorio dei Falegnami in Palermo. The peculiarity of this artefact is the employment of two different supports, upon which both the ground and paint layers are laid: a wooden one, carved and prepared, for the execution of the anatomical parts, and a textile one, sewn, pinned on and stiffened with glue, for the garments. The damage found was mainly attributed to: reaction of the artwork’s materials to the environment, lack of ordinary maintenance, and previous interventions. On the textile support, cleaning was hinde…
Consolidation Comes with Practice: On Ending a Prime Exploratory Journey in the Digital and Public Humanities
2021
With this second issue of magazén’s 2021 volume we are drawing towards the end of a research journey, which involved dozens of international scholars mutually pondering what kind of methodological consolidation was in sight for the wider and heterogeneous field of digital and public humanities after more than two decades in the making.
Of Consolidation and Canons in a Heterogeneous Field Called Digital and Public Humanities
2021
Introduction to magazén issue 2.1 (2021) on "Consolidation" of models, methods and practices in the field of Digital and Public Humanities.
HOW DO FISCAL CONSOLIDATION AND FISCAL STIMULI IMPACT ON THE SYNCHRONIZATION OF BUSINESS CYCLES?
2017
Using quarterly data for a panel of advanced economies, we show that synchronized fiscal consolidation (stimulus) programmes in different countries make their business cycles more closely linked. We also find: (i) some evidence of decoupling when an inflation targeting regime is unilaterally adopted; (ii) an increase in business cycle synchronization when countries fix their exchange rates and become members of a monetary union; (iii) a positive effect of bilateral trade on the synchronization of business cycles. Global factors, such as a rise in global risk aversion and uncertainty and a reversal of nonstandard expansionary monetary policy, can also reduce the degree of co-movement of busi…
Fiscal consolidation and income distribution
2016
This working paper attempts to shed light on distributional effects of recent fiscal consolidation policies, mainly through the channel of in-kind public transfers. We look at the distribution of income in 16 EU countries during the recent global financial and economic crisis, and the subsequent period of fiscal consolidation. Experiences in terms of the depth of the recession and the policies implemented to deal with vary greatly across EU countries. We illustrate this diversity, and show how the crisis has accentuated the differences among EU countries, both in income levels and in inequality. The effects of the public sector on household income distribution have traditionally been measur…
Consolidation by Game-Playing: a Gamesmanship Inquiry into Forestry Industry
2006
If one takes a flight in Finland from the country’s capital, Helsinki, for instance, north to Rovaniemi, the ‘Gateway to Lapland’, the scenery below consists typically of lakes, rivers and marshland, but most of all of forests. Wood in all its forms has been for centuries the core of the national character as well as the locomotive of business in Finland. Over the years the Finns have come to understand that the forest sector is perhaps the strongest guarantor of the Finnish economy and identity. The old saying ‘Finland earns its living from its forests’ can even be interpreted to mean ‘what is good for the forest sector is good for Finland’. Lilja, Tainio and Rasanen (1991a) encapsulated t…
Influence of pre-existing microstructure on mechanical properties of marine ice during compression experiments
2014
AbstractMarine ice is an important component of ice shelves in Antarctica. It accretes in substantial amounts at weak points and below ice shelves. It is likely to exhibit peculiar rheological properties, which are crucial to understanding its potential role in stabilizing ice-shelf flow. Due to its location and consolidation processes, marine ice can present a variety of textures which are likely to influence its rheological properties. We present a new dataset of unconfined uniaxial compression experiments on folded marine ice samples that have been cut at various angles to the folds. Texture and fabric analyses are described ‘before’ and ‘after’ the deformation experiment. It is shown th…
Up with ecology, down with economy? : The consolidation of the idea of climate change mitigation in the global public sphere
2018
Building on theories of valuation and evaluation, we develop an analytical framework that outlines six elements of the process of consolidation of an idea in the public sphere. We then use the framework to analyse the process of consolidation of the idea of climate change mitigation between 1997 and 2013, focusing on the interplay between ecological and economic evaluations. Our content analysis of 1274 articles in leading newspapers in five countries around the globe shows that (1) ecological arguments increase over time, (2) economic arguments decrease over time, (3) the visibility of environmental nongovernmental organizations as carriers of ecological ideas increases over time, (4) the …
