Résumé :
Abstract Organo- and hydrogels have been proposed in the restoration field to treat different types of surfaces. The possibility to retain solvents and to have a controlled and superficial action allowed to use these materials for the removal of very thin layers applied on ancient historical objects, when the under paint layers are particularly delicate and water sensitive. In the last years, an increased attention has been devoted to the proposal of more healthy products to guarantee the safeguard of the operators. Few attention has been devoted to the development of green methods which foresee the use of renewable and biodegradable materials. The aim of this paper is to test a green organo-gel for the cleaning of water sensitive surfaces like varnished egg tempera paintings. The gel has been tested experimented on mock ups varnished with natural and synthetic materials and has been validated on a small portion of a Cimabue painting for the removal of two varnishes applied on two different test areas of the painting.

Résumé :
Abstract Aqueous cleaning of works of art on paper is one of the most important and delicate steps in a conservation process. It allows the removal of inorganic (metals) and organic substances, such as degradation products and other contaminants. These substances are responsible for yellowing, weakening, and loss of mechanical properties of paper. In this article, the cleaning effect of gellan gum was assessed on xuan paper, a traditional Chinese paper different in composition and papermaking technology compared to many Western papers. To assess the effect of gellan gum on xuan paper, its characteristics were studied before and after cleaning utilizing non-invasive and micro-invasive techniques. Results were compared to those obtained when treating Western papers and indicated that gellan gum can be applied effectively for aqueous cleaning of xuan paper.

Résumé :
Abstract The conservation of works of art makes them accessible, and will ensure the transfer of cultural heritage to future generations,. For long term preservation, the development of effective and sustainable conservation materials is of fundamental importance. Although in the past traditional approaches in restoration have used highly effective natural materials for cleaning, modern research has focused on the systematic design of materials and methodologies. For instance, during the nineteenth century conservators reported the use of materials such as vinegar, wine, lemon juice, and today saliva is still used in cleaning applications. Although it is now recognized that these materials contain components that are effective cleaning agents, until recently there has been a lack of systematic studies regarding the control of their structure and reactivity.

Résumé :
In last decades, the safety of both artworks and restorers during cleaning operations, has been the subject of many research works, aimed at the development of gel-systems that confine the solvent action to the very surface thus preventing its absorption into the paint layers and minimizing operators’ exposure. In this research work, a totally sustainable approach has been presented for the cleaning of artworks. In particular new organogels made of bio-compatible components, were evaluated as cleaning tool for the removal of paint varnishes. The gels consist of a polymer derived from renewable bio-materials, poly(-3hydroxybutyrrate), and different green solvents (γ-valerolactone GVL, ethyl lactate EL, dimethyl carbonate DMC). These gels, previously characterized in order to investigate thermal and mechanical properties, were tested for the removal of natural and acrylic varnishes over different binding medium (linseed oil, egg and glue).The gels were first tested on painting mock-ups, not aged and aged, then validated on real paintings. Their cleaning capabilities were compared to methods traditionally employed in restoration (e.g. dimethyl sulfoxide, benzyl alcohol acetone, carbopol-gel). A specific protocol of cleaning evaluation was designed for assessing varnish removal capability, residues releasing and solvent retention by means of Optical Microscope observations of paint cross sections in visible and ultraviolet light, µFTIR-Attenuated Total Reflection surface analyses and Head Space-Solid Phase Micro Extraction coupled with GC-MS analyses. These new totally safe and biodegradable organogels demonstrated good varnish cleaning capabilities that, in conjunction with their easy preparation, use and waste, represent a “green” and safe approach for both paintings and painting restorers.

Dissertação Apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para obtenção do grau de Mestre em Ciências da Conservação, especialização em Pintura
A novel use of ionic liquids as alternative solvents for enzymes in cleaning treatments for the removal of proteinaceous materials from painted or gilded surfaces is presented. The ionic liquids are potentially green solvents to be applied in restoration treatments being also called designer solvents, because of their peculiar properties which can be adjusted by selecting different cationanion combinations. Two ionic liquids were selected: IL1)1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4])and IL2) 1-ethyl-3-methylimidazolium ethylsulfate ([EMIM][EtSO4]). Formulations were prepared with these ionic liquids and two different proteases: one acid (pepsin) and one alkaline (from Aspergillus sojae). Additionally aqueous gel formulations were prepared with these enzymes for reference purpose. A third enzyme provided by the Bromatology Department at the Faculty of Pharmacy from the Porto University was tested only in gel formulation in order to assess its potential use in cleaning treatments. To understand the enzyme activity of these formulations and predict their ability as cleaning agents, analyses were performed with ultraviolet–visible (UV-Vis) spectroscopy and highperformance liquid chromatography (HPLC) prior cleaning; and with matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) after cleaning. These formulations were tested on mock-up samples prepared in accordance with documented and historical sources of artistic techniques of egg tempera and oil painting, and gilding. A non-invasive non-destructive multi-scale analytical protocol was carried out for cleaning effectiveness evaluation and surface characterization before and after treatment. Different surface analytical techniques were adopted to this purpose: stereomicroscopy (SM), optical microscopy (OM) with visible and fluorescence light, atomic force microscopy (AFM), scanning electron microscopy (SEM) and electron dispersive spectroscopy (EDS) and colorimetry (CIE L*a*b* system). The surface analytical protocol proved to be adequate, not only, for monitoring the cleaning process but also for complete characterization of the surface, before and after treatment, including information on the presence of residues and possible surface deterioration. It was also proved that the formulations of enzymes combined with ILs can be used successfully for the removal of proteinaceous material as alternatives to gel formulations. More studies should be conducted to determine the most suitable IL or group of ILs, the main concern should focus on improving aspects such as compatibility with other surface materials, and possible long-term effects of residues after cleaning.

Texte intégral
Résumé :
Using dirt and cleaning as a point of departure, I have examined how categorization and intentionality affects our perception of value. The work is partly performative in its nature where this performativity sets the limelight on the transition between categories: From dirt to craft, from irrational behaviour to art. In the artistic process, I have used coffee rings on table cloths, shoeprints on wallpapers and  the act of mopping as a means of questioning. Through this, I also reveal and question hierarchies in society. The essay discusses and theoretically relates to the artistic work.
Med utgångspunkt i smuts har jag underökt hur kategorisering och intentionalitet påverkar vår uppfattning av värde. Arbetet är delvis performativt till sin natur, där denna performativitet sätter fokus på övergången från en kategori till en annan: Från smuts till konsthantverk, från irrationellt beteende till konst. I den konstnärliga processen har jag använt mig av kafferingar på dukar, skoavtryck på tapeter och moppande av golv som medel för ifrågasättande. PÅ detta vis blottlägger och ifrågasätter jag hierarkier i samhället. I uppsatsen diskuterar jag och relaterar teoretiskt till det konstnärliga arbetet.

D'Alconzo, Nicolo. « Works of art in ancient Greek novels ». Thesis, Swansea University, 2015. https://cronfa.swan.ac.uk/Record/cronfa42452.

Texte intégral
Résumé :
This thesis is a study on the use of works of art in Greek novels, based on the idea that the novelists understood it as one of the main features of their job. I recognise a coherent pattern whereby works of art are closely connected to protagonists and plot, which started already with first-century novels and continued throughout. Chapter One explores rhetorical theory of ekphrasis in order to provide technical information on it as well as to reassess the notion that descriptions of paintings in novels were entirely dependent on rhetoric. Chapter Two starts the analysis of the feature of works of art in the genre by examining Chariton and Xenophon of Ephesus, and by making some considerations on the Ninus romance as well. It shows that works of had a relevant role before the introduction of ekphrasis of paintings, and also that novelists showed a tendency to employ, and innovate on, the ideas of their predecessors. Through close textual analysis of the relevant passages. Chapter Three details how Achilles Tatius composed the ekphraseis of paintings from literary as well as figurative models, and shows how he explored their potential by experimenting on the connection between description and narration. In an appendix, it also examines a possible connection between Achilles Tatius and Lucian. I see Achilles Tatius' descriptions as a prelude to the reflection on the nature of ekphrasis of paintings that can be found in Longus, mostly in the prologue of his novel. Chapter Four is dedicated to this, and connects it to the development of ekphrasis of paintings as an autonomous genre in the third century. Finally, Chapter Five considers Heliodorus as the recipient of this tradition, by looking closely at how he used the story of the birth of his heroine, who is born from a painting, to talk about the birth of his novel. The novelists became progressively aware that art was the expedient through which they could talk about the nature of their work.

Résumé :
This practice-based thesis (comprising of an exegesis, exhibition, performances and their documentation) traces a myriad of cognitive and sub cognitive processes that converge towards a complex practice referred to as 'Aquabatics'. In broad terms, Aquabatics describes the research nexus of occupational diving and contemporary performance. The purpose of this body of research has been to explore underwater performance, behaviour and boarders, in order to both devise new works of live art and to develop new methodologies and approaches to art-making. Aquabatics, as a performance strategy, seeks to critique, contest and explore the liminal natures of human performance, and the role and context of live artists, in contemporary life.

Résumé :
Abstract This paper describes the results of a preliminary investigation of a novel non-contact surface cleaning method for the reclamation of coated cemented carbide cutting tools. Conventional cleaning processes used for cleaning of cutting tools rely either on aqueous methods which are often not very effective, mechanical methods such as grit blasting which can damage the tool cutting edges, or high-temperature chemical stripping methods which significantly reduce the strength and fracture toughness of the tools. In the present work, cobalt-bonded cemented carbide cutting tool inserts coated with titanium carbonitride (TiCN) and alumina (Al2O3) by CVD process were treated by an excimer laser-based technique to effectively remove partially delaminated or poorly bonded coating layers. The goal was to investigate the feasibility of applying a non-contact technique which is environmentally friendly, and is capable of large-scale application and automation. It is postulated that the process works by explosive and thermal shock which essentially delaminate the coating.

Texte intégral
Résumé :
SPM (suspended particulate matters) removal effects of a humidity swing operation where sample air is continuously humidified with heating and dehumidified with cooling were experimentally studied. The experimental results showed that the humidity swing operation reduced SPM ranging from nanometer to micrometer sizes due to multiple phenomena such as suction flow accompanying condensation and thermophoresis, and the total SPM concentration decreased by 80% under the maximum humidity swing condition. The removal mechanisms were theoretically estimated. It was estimated that contributions of the suction and thermophoresis are significant, gravitational sedimentation works above 5 μm size, and the effect of inertial collision is insignificant. Nuclear condensation that markedly changes the SPM size distribution would not be an effective SPM removal effect. The sum of the theoretical estimations is smaller than the experimental result, and study for clarifying the removal mechanisms is necessary. It was also experimentally confirmed that the SPM reduction effects have no dependence on the concentration. The SPM removal experiment in a circulating system was also conducted. With repeatedly applying the humidity swing operation, the SPM concentration for whole size ranges exponentially decreased and converged at certain value. SPM generation by a mechanical pump might occur. With improving the apparatus, this method is expected to become an effective SPM removal method applicable for the SPM from nanometer to micrometer size.

Texte intégral
Résumé :
Abstract Pre-salt oil wells represent huge Flow Assurance challenges for operators both in terms of the complex oil compositions and deep-water conditions. In this paper a field case will be presented with the description of novel wax deposition removal techniques developed case by case to mitigate fouling on production pipelines where a service network is not available. The efficiency of cleaning operations brings not only more stable production but also higher operational efficiency and reduction of emissions per barrel produced. The added challenge of the lack of service network was a constraint specially in terms of keeping acceptable integrity parameters during operations. The methods described on the present article are dynamic operations developed case by case, with the available means, to efficiently clean the production networks. The methods are the so-called diesel soaking, effluent soaking, and gas top-up. All the methods use the shear effect caused by the presence of a viscous fluid and a high velocity gas flow.

Résumé :
Abstract Pre-salt oil wells represent huge Flow Assurance challenges for operators both in terms of the complex oil compositions and deep-water conditions. In this paper a field case will be presented with the description of novel wax deposition removal techniques developed case by case to mitigate fouling on production pipelines where a service network is not available. The efficiency of cleaning operations brings not only more stable production but also higher operational efficiency and reduction of emissions per barrel produced. The added challenge of the lack of service network was a constraint specially in terms of keeping acceptable integrity parameters during operations. The methods described on the present article are dynamic operations developed case by case, with the available means, to efficiently clean the production networks. The methods are the so-called diesel soaking, effluent soaking, and gas top-up. All the methods use the shear effect caused by the presence of a viscous fluid and a high velocity gas flow. The production lines cleaning effectiveness was compared in terms of oil gain, fouling factors reduction, flaring events duration during cleaning operations and improvement of energy efficiency of the plant. The savings with OPEX were also mentioned. Differently from what has been suggested before, it seems that the presence of a high velocity flow is the most important parameters when speaking of cleaning by dynamic methods.

Résumé :
Wall walking robots are designed for different purposes, rescue operations, wall inspections and jobs such as painting and cleaning and fire fighting for tall buildings. These are some cases that these types of robots are extensively used. This paper describes a design of a new serial mechanism for wall climbing job. In deed we are seeking to define a minimum degree of freedom mechanism to be applied in a robot moving vertically on a surface. This mechanism has 5 links, but at any point it works with its 4 links, actually in each cycle of motion the linkage will be interchanged.

Butyrina, Maria, et Valentina Ryvlina. MEDIATIZATION OF ART : VIRTUAL MUSEUM AS MASS MEDIA. Ivan Franko National University of Lviv, février 2021. http://dx.doi.org/10.30970/vjo.2021.49.11075.

Texte intégral
Résumé :
The research is devoted to the study of the phenomenon of mediatization of art on the example of virtual museums. Main objective of the study is to give communication characteristics of the mediatized socio-cultural institutions. The subject of the research is forms, directions and communication features of virtual museums. Methodology. In the process of study, the method of communication analysis, which allowed to identify and characterize the main factors of the museum’s functioning as a communication system, was used. Among them, special emphasis is put on receptive and metalinguistic functions. Results / findings and conclusions. The need to be competitive in the information space determines the gradual transformation of socio-cultural institutions into mass media, which is reflected in the content and forms of dialogue with recipients. When cultural institutions begin to function as media, they take on the features of media structures that create a communication environment localized by the functions of communicators and audience expectations. Museums function in such a way that along with the real art space they form a virtual space, which puts the recipients into the reality of the exhibitions based on the principle of immersion. Mediaization of art on the example of virtual museum institutions allows us to talk about: expanding of the perceptual capabilities of the audience; improvement of the exposition function of mediatized museums with the help of Internet technologies; interactivity of museum expositions; providing broad contextual background knowledge necessary for a deep understanding of the content of works of art; the possibility to have a delayed viewing of works of art; absence of thematic, time and space restrictions; possibility of communication between visitors; a huge target audience. Significance. The study of the mediatized forms of communication between museums and visitors as well as the directions of their transformation into media are certainly of interest to the scientific field of “Social Communications”.

Texte intégral
Résumé :
Although coal has powered the nation for generations and today offers well-paying jobs—often the best opportunities in more rural areas—coal negatively affects human health and the environment at every point in its life cycle: when it is mined, processed, transported, burned, and discarded (Freese, Clemmer, and Nogee 2008). Local communities— often low-income communities and/or communities of color—have for decades borne the brunt of these negative impacts, including air pollution, water pollution, and work- place injuries, illnesses, and fatalities.

Résumé :
This report investigates and develops specifications for using blockchain and distributed organizations to enable decentralized delivery and finance of urban infrastructure. The project explores use cases, including: providing urban greening, street or transit infrastructure; services for street beautification, cleaning and weed or graffiti abatement; potential ways of resource allocation ADU; permitting and land allocation; and homeless housing. It establishes a general process flow for this blockchain architecture, which involves: 1) the creation of blocks (transactions); 2) sending these blocks to nodes (users) on the network for an action (mining) and then validation that that action has taken place; and 3) then adding the block to the blockchain. These processes involve the potential for creating new economic value for cities and neighborhoods through proof-of-work, which can be issued through a token (possibly a graphic non-fungible token), certificate, or possible financial reward. We find that encouraging trading of assets at the local level can enable the creation of value that could be translated into sustainable “mining actions” that could eventually provide the economic backstop and basis for new local investment mechanisms or currencies (e.g., local cryptocurrency). These processes also provide an innovative local, distributed funding mechanism for transportation, housing and other civic infrastructure.

Texte intégral
Résumé :
Atrocity prevention refers to activities to prevent atrocity crimes against civilians. These include genocide, war crimes, crimes against humanity and ethnic cleansing, and can take place in both conflict and non-conflict settings. This points to the need to prioritise and implement atrocity prevention specifically, and not just as part of conflict prevention efforts. Atrocity prevention interventions are broadly of two types: operational (short-term responses) and structural (addressing underlying causes/drivers). These encompass a wide range of approaches including: acting locally (with local actors taking the lead in prevention activities); tackling hate speech, and promoting an independent and strong media; documenting human rights violations, and prosecuting and punishing those responsible (establishing rule of law). The international community should prioritise atrocity prevention, but work in a united manner, take a comprehensive approach, and give the lead to local actors. Atrocity crimes generally develop in a process over time, and risk factors can be identified; these traits make atrocity prevention possible. This rapid review looks at the concept of atrocity prevention, how it is distinct from conflict prevention, the different approaches taken to atrocity prevention, and the lessons learned from these. The review draws on a mixture of academic and grey literature, in particular reports produced by international development organisations such as the United Nations (UN) and USAID. The literature was largely gender-blind (with the exception of conflict-related sexual violence) and disability-blind.
