Résumé :

Modern automotive paints have a complex structure, and modeling their optical properties is a challenge. The inverse problem - the design of the paint composition according to its appearance - is most in demand in practical application. The shortcomings of popular mathematical methods, including previously used by the authors, are analyzed in the paper. A hybrid approach based on deep learning of a neural network and modeling of light propagation in a multilayer paint is proposed. The neural network algorithm solves the problem well for the pigments and paints on which it is trained, but is unstable for new pigments. In this case paint simulation helps to find an acceptable result. The mathematical model here provides only the functional form of the equations in variations, and the values of all functions are obtained by a few measurements which form a pigment library for future use.

Résumé :

Diketopyrrolopyrrole (DPP) is a pigment widely used in modern paints for industrial and artistic applications. Identification of this pigment in paint for art authentication and forensics has previously been accomplished with gas chromatography/mass spectrometry or Laser Raman. Three commercial artist's paints containing DPP were analyzed by x-ray diffraction (XRD). Alpha phase DPP was identified in two of the samples, barite extender the only crystalline component identified in the other sample. In conclusion, XRD analysis of paint samples can identify DPP, as can other organic analyses, but has the advantage of being non-destructive and also identifying the crystal structure. However, the fact that in one sample only extender could be identified does impose some limitations on the analysis of paints.

Résumé :

In this study, we analyzed the rickshaw (Owned by the Daegu Modern History Museum) by measuring each material. The purpose of the study was to identify the materials in modern cultural assets that utilize a variety of materials in a complex way, and establish basic data for preservation and management. Using portable X-ray fluorescence analyzers (P-XRF), species identification, fiber identification, paint film analysis (microscope observation, SEM-EDS, FTIR) on metal, wood, fiber and paint was carried out. Brass, an alloy of Copper, Zinc and Iron, was measured in the metal parts. Further, wooden parts, such as Oak (Quercus acutissima), Japanese Cedar (Cryptomeria japonica), Bamboo (Bambusoideae). Torreya nucifera (Torreya spp.) were identified in the body. Fiber parts consisted mainly of cotton, but some parts were also made of leather. In terms of paint, rickshaws were applied with multiple layers, using cashew (synthetic paint used in place of lacquer). In sum, the rickshaw body part appeared to overlap with layers of fiber, metal (soild), paint, and colored (black, red) layer.

Résumé :

Multilayered automotive paint fragments, which are one of the most complex materials encountered in the forensic science laboratory, provide crucial links in criminal investigations and prosecutions. To determine the origin of these paint fragments, forensic automotive paint examiners have turned to the paint data query (PDQ) database, which allows the forensic examiner to compare the layer sequence and color, texture, and composition of the sample to paint systems of the original equipment manufacturer (OEM). However, modern automotive paints have a thin color coat and this layer on a microscopic fragment is often too thin to obtain accurate chemical and topcoat color information. A search engine has been developed for the infrared (IR) spectral libraries of the PDQ database in an effort to improve discrimination capability and permit quantification of discrimination power for OEM automotive paint comparisons. The similarity of IR spectra of the corresponding layers of various records for original finishes in the PDQ database often results in poor discrimination using commercial library search algorithms. A pattern recognition approach employing pre-filters and a cross-correlation library search algorithm that performs both a forward and backward search has been used to significantly improve the discrimination of IR spectra in the PDQ database and thus improve the accuracy of the search. This improvement permits inter-comparison of OEM automotive paint layer systems using the IR spectra alone. Such information can serve to quantify the discrimination power of the original automotive paint encountered in casework and further efforts to succinctly communicate trace evidence to the courts.

Résumé :

Outdoor sculptures of modern art works are being damaged and deteriorated as they are exposed to the outdoor environment due to the nature of exhibition in the outdoor environment, but secure of basic data through the measures for conservation and advanced researches still remain in the early stage. The surface of “Conversion” which is exhibited in the Busan Cheonmasan Sculpture Park has been exfoliated and deteriorated due to outdoor exhibition for a long time, so systematic conservation and management of works are considered necessary. Prior to the conservation and management, this study conducted observation of cross section, analysis of inorganic components, FT-IR, Raman and Py-GC/Mass analysis to examine the nature and type of paints used for the work through a scientific analysis. As a result of analysis, paints used for the “Conversion” include paint mixed with silvery aluminium powder and white pigment, reddish paint mixed with toluidine red, bluish paint that mixed prussian blue and titanium white and mixture of phthalocyanine blue and titanium white. The result is expected to be used as basic data for selecting materials necessary for conservative treatment of and establishing a plan for conservative treatment of the “Conversion”.

Résumé :

The article presents the results of a study of samples of factory paint and varnish coatings of cars of the "UAZ" and "Volkswagen" model series in accordance with the methods of studying paint and varnish coatings of vehicles in force in the system of forensic departments of the Ministry of Internal Affairs of Russia. When carrying out the study, a set of recommended methods for studying paint and varnish coatings was used - optical microscopy, infrared spectroscopy, electron scanning microscopy with X-ray spectral microanalysis. In the course of the work, the morphological features of the investigated each layer of the studied paint and varnish coatings were determined, and the infrared spectra of these layers were also recorded and interpreted. Based on the analysis of infrared spectra, the qualitative molecular composition of the main components of soils, enamels and varnishes of paint and varnish coatings was determined. Electronic images of cross-sections of paint-and-lacquer coatings of UAZ and Volkswagen vehicles were obtained, as well as X-ray spectra of each layer. The data obtained made it possible to generalize and compare the characteristic features of paint and varnish coatings of each manufacturer. So, for paint and varnish coatings manufactured by Volkswagen, the following characteristics have been determined: the first primers of the samples are made on the basis of a polyester binder containing titanium dioxide in the mineral part, the second primers (fillers) are made on the basis of an acryl-urethane or polyacrylate binder with various modifiers, containing barium sulfate, titanium dioxide and other fillers, the lacquer layers are made on the basis of an acrylic-urethane binder modified with styrene and melamine. The paint and varnish coatings produced by "UAZ" were characterized by the following features: the first primers were made on the basis of an epoxy-ester binder containing various fillers. In the manufacture of the second primers (fillers), an alkyd binder modified with melamine can be used. The available lacquer layers are made on the basis of a polyacrylate binder modified with styrene and melamine. The identified groups of features make it possible to differentiate the paint and varnish coatings of cars of the UAZ and Volkswagen model lines within the framework of the examination of materials, substances and products.

Résumé :

The article shows that techno-genic fillers, based on slag of electrometallurgical production, can be used as fillers for water-dispersion paints, based on polymer composition. For these purposes, it is necessary to modify the slag particles, in order to increase its hydrophobic property. The article examines the effect of the mass of the additive of techno-genic filler, based on the modified slag of the electrometallurgical plant, on the properties of the resulting paint. A water-dispersed acrylic composition, containing stearic acid-modified slag of electric steelmaking production as a filler, has been developed. The composition has high uniformity, is more heat-resistant and water-resistant, a high hiding power and viscosity, and corresponds to modern analogues.

Résumé :

Mat-Eater with Pennants, a rarely exhibited sculpture in Alexander Calder’s oeuvre, was commissioned by The Museum of Modern Art (MoMA) and installed in 1945. To exhibit the large standing mobile in Alexander Calder: Modern from the Start (2021), the derelict sculpture had to be remediated; this initiated a collaborative investigation with conservation scientists, conservators, curators, and the Calder Foundation into the original paint colors hidden beneath layers of repaint. XRF analysis was carried out to elucidate the paints’ composition, followed by sampling for analysis to assess the paint stratigraphy and binders. Scrapings were analyzed by µ-FTIR and Raman spectroscopies; cross sections were examined with optical microscopy and analyzed with SEM-EDS. Analysis differentiated between the original paints, which contain Prussian blue, parachlor red, chrome yellow, and the many layers of overpaint, which contain titanium white, molybdate orange, a variety of β-Naphthol reds, red lead, and ultramarine. A model for Man-Eater, Mobile with 14 Flags, is also part of the museum’s collection, and was first considered as a point of reference for the original colors. Similar analysis, however, indicates that the maquette was painted after the Man-Eater was first installed, therefore is not representative of the original colors. In addition to investigating an early primary palette for Calder’s outdoor sculptures, this study helped develop the plan for the restoration of the original color scheme of Man-Eater.

Résumé :

Art forgeries have existed since antiquity, but with the recent rapidly expanding commercialization of art, the approach to art authentication has demanded increasingly sophisticated detection schemes. So far, the most conclusive criterion in the field of counterfeit detection is the scientific proof of material anachronisms. The establishment of the earliest possible date of realization of a painting, called the terminus post quem, is based on the comparison of materials present in an artwork with information on their earliest date of discovery or production. This approach provides relative age information only and thus may fail in proving a forgery. Radiocarbon (14C) dating is an attractive alternative, as it delivers absolute ages with a definite time frame for the materials used. The method, however, is invasive and in its early days required sampling tens of grams of material. With the advent of accelerator mass spectrometry (AMS) and further development of gas ion sources (GIS), a reduction of sample size down to microgram amounts of carbon became possible, opening the possibility to date individual paint layers in artworks. Here we discuss two microsamples taken from an artwork carrying the date of 1866: a canvas fiber and a paint chip (<200 µg), each delivering a different radiocarbon response. This discrepancy uncovers the specific strategy of the forger: Dating of the organic binder delivers clear evidence of a post-1950 creation on reused canvas. This microscale 14C analysis technique is a powerful method to reveal technically complex forgery cases with hard facts at a minimal sampling impact.

Résumé :

In order to improve the steel structures protection against fire, the intumescent paint method can be applied along with other methods. The intumescent paints layers numbers have to be optimized though. An uniform layer of intumescent paint, foreseen to protect the whole structure, represents both a higher cost and an uneconomical solution. The authors started examination on this problem, by analyzing one of the most recommended steel joints from the earthquake-proof criteria. The conceived and realized original electric furnace allows both a high-accuracy tuning/adjustment of the temperature and a good-stability of its, by means of the original electronic command. In order to perform high-accuracy and full-field monitoring of the displacements, the authors used a modern optical non-contact system, the Video Image Correlation one. The obtained preliminary results are very promising and will be continued in the next period by this international team.

Résumé :

At present, modern ways to protect a varnish coating of cars have become widespread among motorists. Small particles of dirt, dust, winter reagents, minuses of car wash systems, a large number of stones on the road do not have the best effect on car cover. All operational impacts destroy the protective paintwork, after which the steel car body is no longer able to resist the effects of the environment. The body begins to rust and deteriorate. The car eventually loses its appearance, ceases to shine, becomes opaque. Reduction of adverse operational impacts on the paint coating of the car is achieved by modern methods of protection. A wide distribution in the market of automobile cosmetics was produced by protective polishes based on wax or synthetic constituents. It is connected with their small cost and ease of application. The flagship on auto market for the protection of car paint coating is armor plate. This is a protective transparent film with a thickness of approximately 100 microns, providing the maximum degree of protection. Thus, with the help of modern means of protecting paint coating, one can minimize the negative impact of the environment and prolong youth to a car.

Texte intégral

Résumé :

The evolution of damage to building materials has been estimated for the 21stcentury, with a particular focus on aluminum, zinc, copper, plastic, paint, and rubber in urban areas. We set idealized air pollution and climates to represent London and Prague across the period 1950–2100. Environmental parameters were used to estimate future recession, corrosion, and loss of properties through published damage or dose-response functions. The 21stcentury seems to provide a less aggressive environment for stone and metals than recent times. Improvements in air quality are the most relevant drivers for this amelioration. Changes in climate predicted for the 21stcentury do not alter this picture. On the other hand, polymeric materials, plastic, paint, and rubber might show slightly increased rates of degradation, to some extent the result of enhanced oxidant concentrations, but also the possibility of contributions from more solar radiation.

Résumé :

The uses of metal oxide nanoparticles in modern paint and sunscreen formulations are widespread. Through materials characterization and kinetic experiments, it is demonstrated that fresh surface coatings of paint and sunscreen photocatalytically degrade gaseous naphthalene. The primary metal oxides are TiO2 in the form of the rutile phase in paint and as anatase in sunscreen formulations. Other metal oxides present are Al2O3 and ZnO. Several organic fillers that are photochemically active are also present in paint and sunscreen samples but are unidentified. Reaction rate constants increased with increasing air relative humidity, due to the production of surface hydroxyl radical, and decreased with increasing coating thickness, due to mass transfer limitations. Photocatalytic degradation on these freshly generated surfaces is observed to be fast, with naphthalene half-lives shorter than 30 minutes. This work demonstrates that large, semivolatile organic compounds can react photochemically on freshly generated paint- and sunscreen-coated surfaces and may impact air quality in both indoor and outdoor environments.

Résumé :

AbstractScanning electron microscopy backscattered-electron images of paint cross sections show the compositional contrast within the paint system. They not only give valuable information about the pigment composition and layer structure but also about the aging processes in the paint. This article focuses on the reading of backscatter images of lead white-containing samples from traditional oil paintings (17th–19th centuries). In contrast to modern lead white, traditional stack process lead white is characterized by a wide particle size distribution. Changes in particle morphology and distribution are indications of chemical/physical reactivity in the paint. Lead white can be affected by free fatty acids to form lead soaps. The dissolution of lead white can be recognized in the backscatter image by gray (less scattering) peripheries around particles and gray amorphous areas as opposed to the well-defined, highly scattering intact lead white particles. The small particles react away first, while the larger particles/lumps can still be visible. Formed lead soaps appear to migrate or diffuse through the semipermeable paint system. Lead-rich bands around particles, at layer interfaces and in the paint medium, are indications of transport. The presence of lead-containing crystals at the paint surface or inside aggregates furthermore point to the migration and mineralization of lead soaps.

Résumé :

The development of the country is determined by the efficiency of enterprises and organizations, which should simply survive in difficult conditions, and pursue an active strategy of transformation. Innovations in the technology of protective and decorative metal coatings create the necessary level of competition in the domestic paint and varnish coating. Innovative development of the country’s economy is one of the highest priorities of state policy. The strategy of modernization is determined by the consistent transition of the economy to an innovative model of development to solve the problem of strategic support for sustainable and long-term dynamics of innovation processes. However, today there is no necessary level of competition in the domestic innovation market and entrepreneurs are aware of the importance of innovation in creating competitive advantages, as well as an adequate legal framework governing relations in the field of innovation. In addition, the generation of knowledge takes place in the public sphere, the application of this knowledge or the implementation of the obtained scientific and technical results is in the commercial industry. Metal has been and remains the main structural material of the industry – from means of production to consumer products, and the primary consumer properties of the product include its appearance and durability. Rust can kill these qualities in a matter of months and days, so perhaps more important is the quality of the product itself, and the quality of its coating. In this paper, an analysis of modern coating technologies is carried out, the strengths and weaknesses of different coating technologies are identified.

Résumé :

This work presents strategic multi-analytical investigations performed on “Orange Car Crash” by Andy Warhol in order to make a well-informed conservation decision. For determining the type of binding medium used in the artwork, Pyrolysis–Gas Chromatography/Mass Spectrometry (Py–GC/MS) and Thermally Assisted Hydrolysis and Methylation of GC/MS (THM–GC/MS) were employed. The presence of a coating was investigated by Py–GC/MS. Moreover, the comprehension and elucidation of the paint stratigraphy were studied by examining cross-sections of samples taken from both canvases with Optical Microscopy (OM) under reflected visible (Vis) and ultraviolet light (UV) and by Scanning Electron Microscopy with Energy Dispersive X-ray spectroscopy (SEM–EDX). The investigation of possible synthetic organic pigments (SOPs) and extenders was performed by µ-Raman spectroscopy, while micro-Attenuated Total Reflection of Fourier-Transform Attenuated Total Reflection (µ-ATR–FTIR) allowed us to assign each component detected by Py–GC/MS or THM–GC/MS to a specific layer. The data collected from “Orange Car Crash” show mostly the application of acrylic-based paint as well as alkyd with rosin acids-based ink, thus providing fundamental information about the paint stratigraphy and chemical composition of each layer. In addition to the goal of informing an appropriate conservation–restoration strategy, this work represents a rare scientific study of a work by Andy Warhol.

Résumé :

The knowledge of the atmospheric degradation reactions affecting the stability of modern materials is still of current interest. In fact, environmental parameters, such as relative humidity (RH), temperature, and pollutant agents, often fluctuate due to natural or anthropogenic climatic changes. This study focuses on evaluating analytical and statistical strategies to investigate the degradation processes of acrylic and styrene-acrylic paints after exposure to ozone (O3) and RH. A first comparison of FTIR and Py-GC/MS results allowed to obtain qualitative information on the degradation products and the influence of the pigments on the paints’ stability. The combination of these results represents a significant potential for the use of data fusion methods. Specifically, the datasets obtained by FTIR and Py-GC/MS were combined using a low-level data fusion approach and subsequently processed by principal component analysis (PCA). It allowed to evaluate the different chemical impact of the variables for the characterization of unaged and aged samples, understanding which paint is more prone to ozone degradation, and which aging variables most compromise their stability. The advantage of this method consists in simultaneously evaluating all the FTIR and Py-GC/MS variables and describing common degradation patterns. From these combined results, specific information was obtained for further suitable conservation practices for modern and contemporary painted films.

Résumé :

As the improvement of the modern workshop’s demand for cool supply, heating system, how to effectively manage the air-conditioning equipments to satisfy the production skills for air-conditioning system has become an important subject for modern workshop design. This paper comes from the No.1 motorcar company’s project about the automatic air-conditioning system of the car spray-paint workshop. For many reasons, the conventional PID control is difficult to satisfy the car spray-paint production’s strictly demands of the temperature, after a careful research of the object, we utilize the principle of fuzzy PID adaptive control to design a fuzzy PID controller, then put it into the air-conditioning heater’s controlling, through the practice, we find the controller has a good robust property and realized a good control result.

Résumé :

An oil painting by Claude Monet, Port-Goulphar, Belle-Ile 1887 (collection of the Art Gallery of New South Wales), was examined to determine both the identity of the pigments used by the artist in this painting and his technique of mixing colors and laying paint on the canvas. The extremely complex construction of the painting was revealed by optical microscopy, scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDS), and X-ray mapping (XRM) analysis of cross sections of paint flakes excised from damaged regions of Port-Goulphar, Belle-Ile. Nine different pigments were found on the painting. Many of the identified colors were modern pigments that became available only late in the 19th century as a result of scientific advances in pigment chemistry. Although similar colors were available in a natural mineral form, they lacked the vivid color of their manufactured counterparts. The use of these new synthetic metallic oxide colors by Monet accounts for the brilliance of his paintings. In addition, a separation between successive paint layers was observed in some areas of paint chip cross sections, indicating that oil-based paint was applied to paint that had dried, and consequently, Port-Goulphar, Belle-Ile was painted over a long period of time. This observation is contrary to the general perception of Monet's technique of painting freely and quickly.

Résumé :

The growth in the industrial technology and communication sectors has enhanced the usage of electronic gadgets exponentially. Thus, it becomes highly essential to find new solution to utilize or dispose these e-wastes, in order to reduce the e-waste generation. Various reports mentioned that the major component of these e-wastes is their Printed Circuit Boards. Therefore, a new ideology is proposed to use these boards to produce a new coating with good corrosion resistance. At first the boards were separated from the discarded electronic appliances and various electrical elements were separated from these boards. Then the plain circuit boards are pulverized into fine particles and mixed with paint in 3 different proportions ranging from 1:4 to 1:2. The resulting mix was applied over the steel specimen and tested for corrosion resistance. The assessment was done in the aspects of contact angle, weight loss percentage, potentio dynamic polarization technique and electro chemical impedance spectroscopy. From the results it was clear that increase in the addition of printed circuit powder content in the corrosion proof paint coating enhanced the efficiency of the corrosion resistant behaviour 3.5 times than the specimen with uncoated steel specimens. This development of corrosion resistant behaviour of printed circuit powder was attributed from the inertness offered by the presence of silicon dioxides towards the corrosive fluids. Although, the coating of 1:2 proved to be optimum to protect the steel elements from the aggressive corrosion environment, by considering the workability aspects the 1:3 combination was suggested for the innovative development of anti-corrosion paint coating from the e-waste resources. HIGHLIGHTS Life cycles of every electronic wastes end with the hazardous challenging disposals Innovative utilizations of these electronic wastes for the corrosion resistant structural applications were detailed An anti corrosive coating for steel reinforcement was developed from the waste printed circuit boards Coating by printed circuit board powder enhanced 3.5 times more protection from the corrosion GRAPHICAL ABSTRACT

Résumé :

In the minute investigation of old oil canvases, modern art restorers use a technique called rigatino to fill in where flecks of paint are damaged or missing. These fine hatch marks, made with thin paint, signal to later scholars and restorers what constitutes the restorer's work while fully maintaining the distinctiveness and integrity of the original artist's brush strokes. In other words, restorers have devised a straightforward method to indicate the exact positions of evidentiary lacunae and to mark the impositions of their own hand amidst the work of old masters. Unlike the superscripts of footnotes amidst a printed text, rigatino blends with the original picture, though upon close investigation it is always distinct.

Résumé :

Energy conservation is a priority for most of the nation states. Its relevance in modern world energy industry is growing every year. This problem acquires particular importance when a country is characterized by a lack of fuel and energy resources or adverse climatic conditions. The most effective way to reduce heat losses from heat network pipelines to environment is the use of heat insulation. This paper presents the results of application heat-insulating paint on the surface of main pipeline. The infrared thermometry devices (pyrometer and thermal imager) were used to evaluate the energy efficiency of modern high-tech insulation. The thermograms from thermal imager and the readings from pyrometer were analyzed, it was established that the absolute difference in temperatures of an isolated pipeline section and an unpainted section are 5-10 °C. The studies have also shown that when a 250×6 pipeline is coated with a 1 mm thick heat-insulating paint, it will save 126.1 m3 of natural gas per 1 running meter per year. In monetary terms it will be approximately 610 rubles or about $9 (for the first half of 2020). The payback period of this energy-saving measure should not exceed six months. Increasing the thickness of liquid heat insulation layer is not economically feasible. The equivalent fuel economy is approximately 65% when the heat-insulating paint is of 1 mm thickness, and it will increase by only 8% for a thickness of 1.5 mm.

Résumé :

Urban art as a shared expression of street art between artists, citizenship and municipalities has always had an important role in the social life and appearance of modern cities. However, the durability of urban and street artworks is susceptible to the degradation processes that the employed commercial paint formulations undergo once outdoors. These are complex mixtures of compounds, differently sensitive to environmental agents according to their chemical nature. Starting from the colorimetric analysis of murals created in 2010, 2011 and 2018 in Reggio Emilia, Italy, documenting their degradation already after a few months, this study aimed at understanding the stability of the most unstable paints used by the artists in these artworks. A multi-analytical approach evaluated the commercial products under the chemical point of view, after natural and accelerated ageing. Additionally, two manufactured anti-UV varnishes were evaluated for their possible use as coatings. The results pinpointed the weaknesses of the selected paints and highlighted how the application of an anti-UV coating might slightly affect the visual aspect of the artwork, though ensuring a greater resistance to the outdoor conditions due to their minor chemical sensitivity to environmental agents.

Résumé :

Contemporary cinematography reflects the dualism in modern Turkish society. The heart of every inhabitant of Anatolia is dominated by homesickness for his little homeland. This overpowering feeling affects common people migrating in search of work as well as intellectuals for whom Istanbul is a place for their artistic development but not the place of origin. The city and “the rest” have been considered in opposition to each other. The struggle between “the provincial” and “the urban” has even created its own film genre in Turkish cinematography described as “homeland movies”. They paint the portrait of a Turkish middle class intellectual on the horns of a dilemma, the search for a modern identity and a place to belong in a modern world where values are constantly shifting.

Résumé :

A wide range of volatile organic solvents, including aliphatic and aromatic hydrocarbons, alcohols, and ketones, are used in the production of paints, and they comprise more than 30% of the ingredients of paints. The present study was designed to evaluate the occupational exposure to 15 volatile organic compounds (VOCs, including benzene, toluene, ethylbenzene, xylene, styrene, n-hexane, n-heptane, n-nonane, trichloroethylene, tetrachloroethylene, n-butyl acetate, n-octane, n-decane, dichlorofluoromethane, and acetone) in Iranian paint production factories and subsequently, the associated health risks. The samples were collected from the respiratory zone of workers using the NIOSH 1501 method, and their qualitative and quantitative characterization was performed using gas chromatography-mass spectrometry and gas chromatography-flame ionization detector, respectively. The individual concentrations of VOCs ranged from 23.76 ± 0.57 µg m−3 (acetone) to 92489.91 ± 0.65 µg m−3 (m,p-xylene). The predominant compounds were m,p-xylene (up to 92489.91 ± 0.65 µg m−3), ethylbenzene (up to 91188.95 ± 0.34 µg m−3), and toluene (up to 46088.84 ± 0.14 µg m−3). The non-cancer risks of benzene, n-nonane, trichloroethylene, tetrachloroethylene, xylene, and ethylbenzene surpassed the reference value in most of the sectors. In addition, total lifetime risks of cancer were in the range of 1.8 × 10−5–3.85 × 10−3, suggesting that there was a risk of carcinogenesis in all studied sections, mainly due to ethylbenzene and benzene. Considering their high exposure concentrations and their associated non-carcinogenic and carcinogenic risks, biological monitoring of workers and the use of technical and modern engineering control measures are recommended.

Résumé :

The research aim of art creation and presentation is to revitalize traditional glass painting in Indonesia by utilizing plexiglas flexibility as a medium in fine artwork. This is due to the use of glass as a medium is very heavy and easily broken when moved or taken for display. The research method used in the creation of art uses experimental method with the order of exploration stage, design stage, and realization stage. Exploration stage is an exploration activity that explores the source of ideas, including exploring plexiglass materials using various types of water-based and oil-based paints, as well as gravur and grinder techniques to erode the surface. Next is collecting data and references, as well as processing and analyzing data which results are used as the basic for making designs. Design Stage visualizes exploration results into various design alternatives which then the best is chosen and used as references in making works. Realization Stage is the process of manifesting the chosen design into the real work. Research showed that the use of plexiglass material as a medium of traditional glass painting has a very good results, and plexiglas can fully replace glass in terms of aplicable to various paint types, even plexiglas has excellence over ordinary glass that is water-based acrylic paint can be applied better in plexiglas and can fused (compound). Exploration of works visualization using plexiglas as medium has a very good result, as applied to ordinary glass. Exploration of works visualization has a very good result, some works still use traditional motifs and symbols combined with modern motifs and symbols with illustrative, expressionist and pop art style.

AbstractThe formative influence of colonial art education on modern art movements in Africa has not attracted a great deal of scholarly attention. Yet, European art teachers in the Gold Coast challenged colonial prejudice that Africans were incapable of mastering European aesthetic forms. This article analyses the art education provided at the Teacher Training College at Achimota School where pupils learned both to revalue African art forms and to draw and paint in European, representational art styles. Modern artists built on and reshaped what they had learned at Achimota in order to respond to changing social and political conditions. The last section of this article explores the impact of colonial art education on the work of two of the earliest modern artists in Ghana: Kofi Antubam and Vincent Kofi.

Résumé :

This study aims to investigate the chemical stability of some modern paint samples exposed to a new Light Emitting Diode (LED)-lighting system and a halogen lamp by using micro-attenuated total reflectance of Fourier transform infrared spectroscopy (µ-ATR-FTIR), µ-Raman, pyrolysis—gas chromatography/mass spectrometry (Py-GC/MS), and thermally assisted hydrolysis and methylation of GC/MS (THM-GC/MS). Those investigations were performed before and after the exposure of the samples to lightings for 1250, 2400, 3300, and 5000 h. The results obtained with µ-Raman spectroscopy show the high stability of the selected inorganic pigments after the exposure to the lighting systems; while similar to the UV/Vis/NIR results reported in a previous study, µ-ATR-FTIR and THM-GC/MS results evidence greater chemical changes occurring principally on the linseed oil binder-based mock-ups among the acrylic and alkyd-based samples. Moreover, principal component analyses (PCA) and hierarchical cluster analyses (HCA) of THM-GC/MS results highlight that those changes were mostly dependent on the exposure time and on the type of pigment, while being independent of the lighting system used. Finally, semi-quantitative µ-ATR-FTIR results show slight pigment enrichment at the paint surface due to the auto and photo-oxidative degradation of the linseed oil binder.

Microscopy is of vital importance in the real world of the forensic scientist. In today's society, physical evidence is critical to the criminal justice system for the detection, investigation and prosecution of criminal acts. A trail of microscopic fibers led investigators in Atlanta to the conviction of the serial killer, Wayne Williams. Flecks of paint on a hit-run victim, analyzed microscopically, can be compared with the paint on a suspect vehicle to exclude or match it to the crime. The forensic firearms examiner compares the microscopic striations on a bullet to match it to the gun it was fired from. Microscopes are used throughout the modern forensic laboratory. They are essential in searching for evidence. They aid the examiner in identifying and comparing trace evidence. As the scales of justice symbolize forensic science, microscopes symbolize the trace evidence examiner.Because of the variety of physical evidence, forensic scientists use several types of microscopes in their investigations.

His biographers paint an image of an austere presence, reserved manner, shyness, economy of gestures and an impenetrable, impassive face. However, a wry and sarcastic side of Charcot can be demonstrated in several situations, and these examples help to clarify the intricacies of his personality and work style.

Résumé :

This paper deals with the “modern” plaster mortars based on air lime, hydraulic lime, and cement used between the 1950s and 1990s of the last century, taking, as a case study, a historical building of the Cagliari city whose foundations and ground floor are cut into in-situ limestone. Different plaster layers (i.e., arriccio and intonachino, paint), applied on the excavated limestone walls, were collected from cave-room. All samples were analysed by optical and electron (SEM-EDS) microscopy and X-ray diffractometry (XRD) in order to define their microstructures, textures and compositional features. In addition, real and bulk density, water and helium open porosity, water absorption kinetic, and saturation index were measured. By microscopic imaging analyses, the binder/aggregate ratio as vol.% was determined. Results revealed that cement mortars, composed mainly of C-S-H, C-A-H, and C-F-H phases, given their high hydraulicity, low open porosity, and a rigid behaviour, showed a good chemical but not physical–mechanical adherence, as they were often found detached from the substrate and frequently loaded with salt efflorescence. On the contrary, the hydraulic lime-based mortars, characterised by a binder composed of C-S-H and C-A-H phases and calcite derived from the portlandite carbonation, showed a greater affinity with limestone substrate and other plasters. Thus, they are more suitable to be used as a repair mortar, showing a long durability on the time. The thin air lime-based plasters (intonachino) showed a good adhesion to the substrate, exerting their coating function better than the harder, cement-based mortars. Lime-based wall paints have a good chemical adhesion and adaptability to the irregular surface of the substrate, due to low thickness of lime paint layers (<1 mm) that confers an elastic physical behaviour.

Résumé :

Development of modern high-end coatings is a challenge. At this point, the problem of the range and quality of corrosion-resistant materials is one of the most serious in the Russian paint industry. The article deals with some aspects of obtaining anticorrosive materials, applied and operated in adverse conditions. Binder and solvents were selected, were found the optimal working concentration of the film-forming solution, were selected conditions of dispersing. Also was selected anticorrosion pigment, were studied its surface properties, the optimal concentration was chosen.
