The determination of the pollutants was made by gas chromatography-mass spectroscopy (GC/MS). According to the results, the sediments are heavily polluted by DDTs and moderately to highly polluted by PCBs and PAHs. A Geographic Information System was used to map and investigate the spatial distribution of these pollutants. The distribution maps show a tendency for the pollutants to accumulate at the entrance of the harbour, from where they most probably diffuse towards the open sea of the Saronikos gulf.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="4814394186ac0fc557a86a0d22e62608" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44516799,"asset_id":24176584,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44516799/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="24176584"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="24176584"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 24176584;

Low cost ECD processing of ternary CuInSe2 and quaternary Cu(In,Ga)Se2 chalcopyrite semiconductor films with crystal quality similar to that of PVD grown films was achieved by as few as possible process steps skipping selenization at elevated temperatures. Chalcopyrite phase formation was confirmed already in as-deposited films. The film quality was further improved by subsequent annealing at 300oC, for 2h, in N2.

It comprises the microscopic structure description of polymers, separation of component phases and determination of chemical elements of additives that we use. For this purpose we have used scanning electronic microscope (SEM) JEOL6380LV equipped with the system of energy dispersion spectroscopy (EDS). The plastic materials were provided by companies operating in the Albanian market. They are used in the fabrication of plastic bags, of packaging materials for transportation of products, and also, as construction materials. So far, we have studied 6 different polyethylene samples, one industrially clean PE sample and 5 other recyclable PE samples. Plastic packaging materials are considered an important source of environmental waste mainly due to their large friction by waste in the waste stream. We used SEM to study the microstructure of our samples. EDX analysis was used to investigate additives in the recyclable materials. Raw material of polyethylene was provided in granular shape which we transformed to plastic pellets with a smooth surface. Pellets were formed using a specific temperature-time plan during molding. Uniform pellets with smooth surfaces were formed when the polymers passed the viscoelastic state, e.g. a temperature of 180 o C, higher than the melting temperature of polyethylene and lower than the temperature that damages many plastic materials and their dyers. Cleaning and drying of the pellet surfaces was a key parameter in order to acquire images of high quality and resolution.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="29b7a1a29b7a8e34e35fe341b61ea007" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44516797,"asset_id":24176580,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44516797/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="24176580"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="24176580"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 24176580;

To understand the observed spectra, laboratory experiments must be performed to compare the spectral features of individual systems under controlled physical and chemical conditions (individual species concentration, temperature, pressure, and electron density). Asteroids are remnants from the materials that first formed the planetesimals and planets, and meteorites are pieces of asteroids on Earth that allow us to measure many of the properties of their parent bodies in detail. However, a fundamental problem exists in linking specific meteorites to their parent bodies (primary matter, asteroids, and comet nuclei). Most meteoroids are also completely desintegrated during the descent through the atmosphere and spectroscopic records remain the only information about their composition. Detailed description and understanding of their spectroscopy and behavior in atmosphere are therefore a challenging scientific problem worth studying. First, our target is a systematization of spectroscopic emission lines for the comparative analysis of meteor spectra. Samples of meteorites have been irradiated using excimer laser. Additionally discharge and LIDB plasma in gas media representing various atmospheres (O 2 , N 2 , Ar, and CO 2 ) have also been characterized.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="d40881eb3a6df17ab3af9a223e2136c8" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":41608206,"asset_id":20873514,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/41608206/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873514"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873514"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873514;

Despite their differences in the methods of treatment for conservation purposes, laser tools are similar and we have chosen to treat them in parallel. Historical books and paper documents have a variety of surface alterations due to dirt encrustation or discoloration from the storage conditions and humidity. Biological deteriorations play an important role too. We currently proceed to the application of laser cleaning and diagnosis of biological stains (such as fungus) from cultural heritage books, identifying best practices and optimum laser parameters (i.e., energy dose). The method is applied to an historical book of the NTUA-Historic Library. The paper surface is cleaned using 355nm pulsed laser with fluence threshold of 0.102J/cm2 with 5Hz repetition rate and 160s exposure. The diagnostic technique available for the characterization of the paper surface is optical microscopy and SEM/EDX analyses. Ancient coins and metallic artworks develop patina or have encrustations from soil and other impurities. Lasers have been used in cleaning old coins and metallic artworks of cultural interest. A number of 18 coins from the 19th and 20th century are cleaned. In the current paper only a silver coin and a copper coin from the 20th century are presented. These coins are cleaned with a Q-Switched Nd:YAG laser with two different wavelengths 213nm and 1064nm. The cleaning performance of these two wavelengths is determined with optical microscopy and SEM/EDX analyses. Surface topography and composition are investigated. The chemical composition of the contamination seems to play an important role in metal deterioration during the cleaning process and therefore precise characterisation is very significant prior to and after cleaning.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873512"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873512"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873512;

Biodentine and ProRoot MTA were prepared and packed into the canal lumen of dentin disks. Twenty specimens of each material were further randomly divided into two groups according to the storage media: group A: materials with saline as storage medium; group B: materials with citric acid buffered at pH 5.4 as storage medium. The sealing ability was evaluated at 1, 3, 6, and 24 h and 1 or 3 months, using a fluid transport model for quantitative analysis of endodontic microleakage. The morphological microstructures of the materials were also evaluated using scanning electron microscopy. During the first 24 h, MTA showed greater fluid transport values than Biodentine in both environments. At the 3-month measurement, when the materials were stored in saline, MTA showed greater ability to prevent fluid movement than Biodentine (p &amp;amp;amp;lt; 0.0001). However, when the materials were stored in an acidic environment, no statistical significant difference was found after 3 months. After storage in saline, both materials showed an uneven crystalline surface with similar hexagonal crystals. The microstructure of Biodentine changed after exposure to citric acid, showing a relatively smooth surface with more spheroidal crystals. The exposure to an acidic environment, within the limits of this study, seems to result in morphological changes of Biodentine in a different manner than MTA. MTA shows good ability to prevent fluid movement over time, in both environments. The ability of Biodentine to prevent fluid movement over time was enhanced in the acidic environment. The findings of the present study could imply that both materials are indicated for use in an acidic environment.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873511"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873511"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873511;

The hollow ovoid in Nakhla is interpreted to be the result of a shock event from a bolide impact that induced circulating hydrothermal fluids with sharp temperature gradients in the subsurface of Mars, which variably altered the parent rock. This seems to be more evident now, with the additional discovery of two phases of phyllosilicate minerals, one of which is an iron-rich chlorite, and the other is probably a mixed-layer phyllosilicate. These phyllosilicates are located in the same thin section of Nakhla, very close to where the ovoid was also found (Chatzitheodoridis et al., 2014).

Only then fully automated interpretation can be performed, also resulting in detailed chemical patterns that can be useful for biosignature interpretation. Currently, biosignature interpretation is performed using a small number of characteristic peaks that are compared with pure, isolated biochemical phases, often assisted by statistical techniques, or by labelling specific molecules. Biochemical phases that have been investigated in the literature include proteins and their aminoacids (Quong et al., 2005), extracellular polymeric substances (de Brouwer et al., 2006), lipid...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="2a8cb8603a3a2a8307d557c93ff3c298" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":41608191,"asset_id":20873505,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/41608191/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873505"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873505"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873505;

The latter indices have a measurable effect on the mechanical properties of aggregates–binder mixtures, e.g. concrete, mortar, bituminous mixtures. In this work, digital methods were developed with the mathematical software Matlab, by applying a statistical method called k-means clustering for the exact separation between background and aggregates to compute the aforementioned properties. The overall code can be ap-plied in real time by analysing quickly a large volume of data with accuracy and significant cost reduction. Currently, only the two dimensions of the grains could be measured. Future work will focus on full three-dimensional measurements by com-paring paired images taken from different angles but also aggregate segmentation in case of touching particles.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5ce229d218944894357fd12ea3a0d2bd" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":42386751,"asset_id":20873504,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/42386751/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873504"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873504"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873504;

Despite their differences in the methods of treatment for conservation purposes, laser tools are similar and we have chosen to treat them in parallel. Historical books and paper documents have a variety of surface alterations due to dirt encrustation or discoloration from the storage conditions and humidity. Biological deteriorations play an important role too. We currently proceed to the application of laser cleaning and diagnosis of biological stains (such as fungus) from cultural heritage books, identifying best practices and optimum laser parameters (i.e., energy dose). The method is applied to an historical book of the NTUA-Historic Library. The paper surface is cleaned using 355nm pulsed laser with fluence threshold of 0.102J/cm2 with 5Hz repetition ...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873503"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873503"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873503; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=20873503]").text(description); $(".js-view-count[data-work-id=20873503]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 20873503; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='20873503']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=20873503]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":20873503,"title":"Use of Lasers for Cleaning of Paper Documents and Coins","internal_url":"https://www.academia.edu/20873503/Use_of_Lasers_for_Cleaning_of_Paper_Documents_and_Coins","owner_id":195104,"coauthors_can_edit":true,"owner":{"id":195104,"first_name":"Elias","middle_initials":null,"last_name":"Chatzitheodoridis","page_name":"EliasChatzitheodoridis","domain_name":"ntua","created_at":"2010-05-31T05:10:45.382-07:00","display_name":"Elias Chatzitheodoridis","url":"https://ntua.academia.edu/EliasChatzitheodoridis"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="20873502"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/20873502/poster_bulgaria_2014_EC2"><img alt="Research paper thumbnail of poster bulgaria 2014 EC2" class="work-thumbnail" src="https://attachments.academia-assets.com/41608192/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/20873502/poster_bulgaria_2014_EC2">poster bulgaria 2014 EC2</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Moving forward in the century of e-books, historical books became significant cultural heritage t...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Moving forward in the century of e-books, historical books became significant cultural heritage treasures, and their preservation an important issue for the conservators. However, the conventional methods for cleaning paper and manuscripts still require being improved and upgraded, by the use of modern technologies, such as lasers and analytical methods for diagnosis. Lasers provide controlled energy, thus being an accurate tool for scientists, while several diagnostic techniques are available for visualizing and analyzing the resulting treatment in microscale. In this study we present the laser cleaning as an effective technique for removing fungi from paper samples and an historic book. Diagnosis of successfully treated areas by optical microscopy reveals no damage to the paper substrate, hence proving that lasers have considerable potential for nondestructive paper conservation.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ea4a5d75b1ae1060eed807f153574a59" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":41608192,"asset_id":20873502,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/41608192/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873502"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873502"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873502;

The determination of the pollutants was made by gas chromatography-mass spectroscopy (GC/MS). According to the results, the sediments are heavily polluted by DDTs and moderately to highly polluted by PCBs and PAHs. A Geographic Information System was used to map and investigate the spatial distribution of these pollutants. The distribution maps show a tendency for the pollutants to accumulate at the entrance of the harbour, from where they most probably diffuse towards the open sea of the Saronikos gulf.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="4814394186ac0fc557a86a0d22e62608" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44516799,"asset_id":24176584,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44516799/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="24176584"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="24176584"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 24176584;

Low cost ECD processing of ternary CuInSe2 and quaternary Cu(In,Ga)Se2 chalcopyrite semiconductor films with crystal quality similar to that of PVD grown films was achieved by as few as possible process steps skipping selenization at elevated temperatures. Chalcopyrite phase formation was confirmed already in as-deposited films. The film quality was further improved by subsequent annealing at 300oC, for 2h, in N2. ZnSe buffer- and ZnO window-layers were processed by CBD and ECD techniques, respectively.

Initially they were identified with the vibration spectroscopy FT-IR and Raman, which marked the presence of additives in recycled samples. As recycling process was used as a micro-pilot system; comprising the melt flow index device and a universal mill grinding. Among mechanical properties that were identified were density, specific gravity, melt flow index, yield strength and elasticity modulus and tensile strength. From the results analysis were observed changes in physical and mechanical properties for polyethylene samples by recycling cycles.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="964779b8916254b669edbb4e6dd67bb4" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44516798,"asset_id":24176582,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44516798/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="24176582"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="24176582"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 24176582;

It comprises the microscopic structure description of polymers, separation of component phases and determination of chemical elements of additives that we use. For this purpose we have used scanning electronic microscope (SEM) JEOL6380LV equipped with the system of energy dispersion spectroscopy (EDS). The plastic materials were provided by companies operating in the Albanian market. They are used in the fabrication of plastic bags, of packaging materials for transportation of products, and also, as construction materials. So far, we have studied 6 different polyethylene samples, one industrially clean PE sample and 5 other recyclable PE samples. Plastic packaging materials are considered an important source of environmental waste mainly due to their large friction by waste in the waste stream. We used SEM to study the microstructure of our samples. EDX analysis was used to investigate additives in the recyclable materials. Raw material of polyethylene was provided in granular shape which we transformed to plastic pellets with a smooth surface. Pellets were formed using a specific temperature-time plan during molding. Uniform pellets with smooth surfaces were formed when the polymers passed the viscoelastic state, e.g. a temperature of 180 o C, higher than the melting temperature of polyethylene and lower than the temperature that damages many plastic materials and their dyers. Cleaning and drying of the pellet surfaces was a key parameter in order to acquire images of high quality and resolution.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="29b7a1a29b7a8e34e35fe341b61ea007" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44516797,"asset_id":24176580,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44516797/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="24176580"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="24176580"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 24176580;

However, a fundamental problem exists in linking specific meteorites to their parent bodies (primary matter, asteroids, and comet nuclei). Most meteoroids are also completely desintegrated during the descent through the atmosphere and spectroscopic records remain the only information about their composition. Detailed description and understanding of their spectroscopy and behavior in atmosphere are therefore a challenging scientific problem worth studying. First, our target is a systematization of spectroscopic emission lines for the comparative analysis of meteor spectra. Samples of meteorites have been irradiated using excimer laser. Additionally discharge and LIDB plasma in gas media representing various atmospheres (O 2 , N 2 , Ar, and CO 2 ) have also been characterized.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="d40881eb3a6df17ab3af9a223e2136c8" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":41608206,"asset_id":20873514,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/41608206/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873514"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873514"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873514;

Despite their differences in the methods of treatment for conservation purposes, laser tools are similar and we have chosen to treat them in parallel. Historical books and paper documents have a variety of surface alterations due to dirt encrustation or discoloration from the storage conditions and humidity. Biological deteriorations play an important role too. We currently proceed to the application of laser cleaning and diagnosis of biological stains (such as fungus) from cultural heritage books, identifying best practices and optimum laser parameters (i.e., energy dose). The method is applied to an historical book of the NTUA-Historic Library. The paper surface is cleaned using 355nm pulsed laser with fluence threshold of 0.102J/cm2 with 5Hz repetition rate and 160s exposure. The diagnostic technique available for the characterization of the paper surface is optical microscopy and SEM/EDX analyses. Ancient coins and metallic artworks develop patina or have encrustations from soil and other impurities. Lasers have been used in cleaning old coins and metallic artworks of cultural interest. A number of 18 coins from the 19th and 20th century are cleaned. In the current paper only a silver coin and a copper coin from the 20th century are presented. These coins are cleaned with a Q-Switched Nd:YAG laser with two different wavelengths 213nm and 1064nm. The cleaning performance of these two wavelengths is determined with optical microscopy and SEM/EDX analyses. Surface topography and composition are investigated. The chemical composition of the contamination seems to play an important role in metal deterioration during the cleaning process and therefore precise characterisation is very significant prior to and after cleaning.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873512"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873512"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873512;

Biodentine and ProRoot MTA were prepared and packed into the canal lumen of dentin disks. Twenty specimens of each material were further randomly divided into two groups according to the storage media: group A: materials with saline as storage medium; group B: materials with citric acid buffered at pH 5.4 as storage medium. The sealing ability was evaluated at 1, 3, 6, and 24 h and 1 or 3 months, using a fluid transport model for quantitative analysis of endodontic microleakage. The morphological microstructures of the materials were also evaluated using scanning electron microscopy. During the first 24 h, MTA showed greater fluid transport values than Biodentine in both environments. At the 3-month measurement, when the materials were stored in saline, MTA showed greater ability to prevent fluid movement than Biodentine (p &amp;amp;amp;lt; 0.0001). However, when the materials were stored in an acidic environment, no statistical significant difference was found after 3 months. After storage in saline, both materials showed an uneven crystalline surface with similar hexagonal crystals. The microstructure of Biodentine changed after exposure to citric acid, showing a relatively smooth surface with more spheroidal crystals. The exposure to an acidic environment, within the limits of this study, seems to result in morphological changes of Biodentine in a different manner than MTA. MTA shows good ability to prevent fluid movement over time, in both environments. The ability of Biodentine to prevent fluid movement over time was enhanced in the acidic environment. The findings of the present study could imply that both materials are indicated for use in an acidic environment.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873511"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873511"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873511;

The hollow ovoid in Nakhla is interpreted to be the result of a shock event from a bolide impact that induced circulating hydrothermal fluids with sharp temperature gradients in the subsurface of Mars, which variably altered the parent rock. This seems to be more evident now, with the additional discovery of two phases of phyllosilicate minerals, one of which is an iron-rich chlorite, and the other is probably a mixed-layer phyllosilicate. These phyllosilicates are located in the same thin section of Nakhla, very close to where the ovoid was also found (Chatzitheodoridis et al., 2014). Chlorite is a very common hydrous, layered silicate mineral on Earth, very similar in nature to micas.

In a previous work we concluded that it is possible to interpret TOF-SIMS mass spectra in detail, however, interpretation requires powerful proprietary software to handle the information (Chatzitheodoridis et al., 2005) and a perfect mass calibration (Antonopoulou-Athera et al., 2011). Only then fully automated interpretation can be performed, also resulting in detailed chemical patterns that can be useful for biosignature interpretation. Currently, biosignature interpretation is performed using a small number of characteristic peaks that are compared with pure, isolated biochemical phases, often assisted by statistical techniques, or by labelling specific molecules. Biochemical phases that have been investigated in the literature include proteins and their aminoacids (Quong et al., 2005), extracellular polymeric substances (de Brouwer et al., 2006), lipid...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="2a8cb8603a3a2a8307d557c93ff3c298" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":41608191,"asset_id":20873505,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/41608191/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873505"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873505"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873505;

The latter indices have a measurable effect on the mechanical properties of aggregates–binder mixtures, e.g. concrete, mortar, bituminous mixtures. In this work, digital methods were developed with the mathematical software Matlab, by applying a statistical method called k-means clustering for the exact separation between background and aggregates to compute the aforementioned properties. The overall code can be ap-plied in real time by analysing quickly a large volume of data with accuracy and significant cost reduction. Currently, only the two dimensions of the grains could be measured. Future work will focus on full three-dimensional measurements by com-paring paired images taken from different angles but also aggregate segmentation in case of touching particles.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5ce229d218944894357fd12ea3a0d2bd" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":42386751,"asset_id":20873504,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/42386751/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873504"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873504"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873504;

Despite their differences in the methods of treatment for conservation purposes, laser tools are similar and we have chosen to treat them in parallel. Historical books and paper documents have a variety of surface alterations due to dirt encrustation or discoloration from the storage conditions and humidity. Biological deteriorations play an important role too. We currently proceed to the application of laser cleaning and diagnosis of biological stains (such as fungus) from cultural heritage books, identifying best practices and optimum laser parameters (i.e., energy dose). The method is applied to an historical book of the NTUA-Historic Library. The paper surface is cleaned using 355nm pulsed laser with fluence threshold of 0.102J/cm2 with 5Hz repetition ...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873503"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873503"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873503; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=20873503]").text(description); $(".js-view-count[data-work-id=20873503]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 20873503; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='20873503']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=20873503]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":20873503,"title":"Use of Lasers for Cleaning of Paper Documents and Coins","internal_url":"https://www.academia.edu/20873503/Use_of_Lasers_for_Cleaning_of_Paper_Documents_and_Coins","owner_id":195104,"coauthors_can_edit":true,"owner":{"id":195104,"first_name":"Elias","middle_initials":null,"last_name":"Chatzitheodoridis","page_name":"EliasChatzitheodoridis","domain_name":"ntua","created_at":"2010-05-31T05:10:45.382-07:00","display_name":"Elias Chatzitheodoridis","url":"https://ntua.academia.edu/EliasChatzitheodoridis"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="20873502"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/20873502/poster_bulgaria_2014_EC2"><img alt="Research paper thumbnail of poster bulgaria 2014 EC2" class="work-thumbnail" src="https://attachments.academia-assets.com/41608192/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/20873502/poster_bulgaria_2014_EC2">poster bulgaria 2014 EC2</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Moving forward in the century of e-books, historical books became significant cultural heritage t...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Moving forward in the century of e-books, historical books became significant cultural heritage treasures, and their preservation an important issue for the conservators. However, the conventional methods for cleaning paper and manuscripts still require being improved and upgraded, by the use of modern technologies, such as lasers and analytical methods for diagnosis. Lasers provide controlled energy, thus being an accurate tool for scientists, while several diagnostic techniques are available for visualizing and analyzing the resulting treatment in microscale. In this study we present the laser cleaning as an effective technique for removing fungi from paper samples and an historic book. Diagnosis of successfully treated areas by optical microscopy reveals no damage to the paper substrate, hence proving that lasers have considerable potential for nondestructive paper conservation.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ea4a5d75b1ae1060eed807f153574a59" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":41608192,"asset_id":20873502,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/41608192/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20873502"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20873502"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20873502;

Microscopic observations on zircons separated from a garnet gneiss revealed a simple zoned structure consisting of a somewhat rounded detrital core and a metamorphic overgrowth rim. Numerous mineral and fluid inclusions were found in the metamorphic rim especially near the interface of the two domains. We carried out a detailed laser µ-Raman spectroscopic study of the inclusions and their zircon host in both domains. Quartz and monazite were identified in the detrital core whereas diamond, albite, phengite, hematite, rutile and CO 2 gas were identified in the rim. Interestingly, albite occurs always in pockets with phengite and diamond whereas the latter two phases can occur independently. We interpret these pockets as precipitates from a melt phase at high pressures. The microdiamonds were probably formed by dissociation of CO2 ; the thus liberated oxygen was combined with iron available from the fluid / melt phase to precipitate hematite. Importantly, there is clear-cut distinction in the Raman spectra of detrital and rim zircon, with the latter being additionally characterised by a broad band at ~1332 cm-1. What is more significant is that by approaching the included diamonds the above band in zircon increases dramatically in intensity. This can either be assigned to carbon occupying interstitial sites in zircon and in all probability reflects a luminescence band or to enhanced carbon solubility in zircon (Shcheka et al., 2006), with the diamonds reflecting sites locally supersaturated in carbon. We favour the former explanation since similar bands, often associated with CO2 peaks, were also observed in inclusions in garnet for which C solubility is negligible.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="52139a3d083e51ed81bd449236a47f0a" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":41528230,"asset_id":20727621,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/41528230/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="20727621"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="20727621"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 20727621;
