Abstract:
Currently, enameled steel products are becoming very popular in construction, since they have a number of valuable properties that noticeably distinguish enameled architectural and construction panels against the background of other facing building materials. Also, extremely urgent is the problem of obtaining glass enamel coatings for architectural and construction panels with high properties. In the work, glass-crystalline enamel coatings in the system R2O–RO–B2O3–Al2O3–SiO2–TiO2–P2O2–F- were studied, the features of their formation on facing steel panels were revealed. The physicochemical and aesthetic-consumer properties of the developed enamel coatings have been investigated. The influence of the chemical composition of titanium-containing glass and the crystallization process on the whiteness index of white coating glass-crystalline enamels and the characteristic color shade was studied using a spectrophotometric method using an RGB color measurement model. This method made it possible to accurately determine the shades of the obtained glass-crystalline enamel coatings for steel.

Abstract:
Sheet steel enamels with mill addition of quartz glass were manufactured successfully in accordance with the ordinary enamel manufacturing technology. The effect of mill addition of quartz glass on thermal shock resistance and acid resistance of enamels was analyzed through XRD and SEM etc. The results show that the thermal shock of the enamel can be increased greatly by mill addition of quartz glass, and there is the rational range of mill addition of quartz glass in order for the enamel to achieve both the superior acid resistance and the excellent thermal shock.

Abstract:
Porcelain enamel is an inorganic-type coating, which is applied to metals or glass for both decorative and functional purposes. This coating is a silica-based solidified glass mass obtained by high-temperature firing (temperature can range between 450 and 1200 °C depending on the substrate). Porcelain enamel coatings differ from ceramic coatings mainly by their glass structure and dilatation coefficient, and from organic paints mainly by the inorganic nature of the matrix and the chemical bond that exists between the coating and the substrate.

The results of an investigation of the chemical and thermal characteristics of glass-ceramic enamels, derived from the Li2O-Na2O-Al2O3-TiO2-SiO2 system obtained by employing the methods of mathematical experiment planning, are presented in this paper. Adequate mathematical models, showing the dependence of the chemical and thermal stability on the chemical composition of enamel systems, after different thermal treatment procedures, were obtained. Based on the testing carried out, it was concluded that in the obtained glass-ceramic enamels the chemical resistance is decreased, but at the same time, the thermal stability is increased, relative to reference coatings.

Abstract:
It is known that enamel coatings with enhanced protective and decorative properties can be fabricated on the basis of boron-silicate glass frits with an increased content of TiO2 in their composition. Opacity and white color of enamel coatings are due to their crystallization at firing temperatures. Titanium glass enamels are not pure white visually, and show yellow and blue shades depending on their chemical composition. The purpose of this work was to establish the influence of basic components on the water resistance and color characteristics of titanium enamel coatings. Our experimental study was focused on the glass frits with the chemical composition described by the generalized formula (76–n–m)SiO2nB2O3mNa2O24MexOy, where MexOy is the total content of TiO2, ZrO2, Al2O3, MgO, СaO, P2O5, and K2O. It was found that the glass frits with the following content of basic components (mol.%): Na2O 12–13, K2O 3, B2O3 10–11, SiO2 49–51 demonstrated the highest water-resistant properties. The color characteristics of titanium enamel coatings prepared on the basis of the mentioned glass frits differ significantly from the reference white light A; the titanium enamel coatings under consideration have a yellow-green tint. The highest deviations of the enamel coating color purity and color tone from a standard of white color were observed when increasing the Na2O content in the glass frits composition at the expense of SiO2. The color of titanium coatings with the highest water resistance has a deviation from the standard of white color within 4–6%.

Abstract:
One of the technologies for obtaining and storing high-quality silage and haylage is the use of silo towers. The authors propose to manufacture silo towers from high-strength and corrosion-resistant steel sheets, coated with glass enamel, which has a lower coefficient of sliding friction than steel and concrete, as well as high resistance to aggressive environments. The aim of the study was to determine the properties of the glass-enamel coating of steel parts for the manufacturing of tower-type storages. A glass-enamel coating from a frit of glass-enamel brand MK-5 was applied to prepared sheets of steel 09G2S using a spray gun. The total thickness of the enameled coating ranged from 200 to 350 nm. Steel sheets were baked at a temperature of 850°C for 30 minutes. The thickness of the enamel coating was determined with an Olympus GX51 microscope. The roughness was determined using a TAYLOR HOBSON Surtronic 25 profilometer. The adhesive properties of the coating were studied using a Positest AT-M adhesive meter. Each test piece was tested twice. The tests were carried out on a sheet of 0.06 m2. The coefficient of sliding friction was determined on an adapted test bench. Laboratory tests with silage mass were carried out according to the developed methodology. Studies of the steel surface with a glass-enamel coating showed that the average thickness of the enameled layer was 690 nm, the roughness was 0.01 μm, and the adhesion was 5.25 MPa. The sliding friction coefficient of sliced plant materials on the enameled steel surface was 0.15, which is 2.6 and 3.2 times lower than that of non-enamelled steel and concrete, respectively. The authors have made conclusions about the possibility of using steel 09G2S in silo towers as a suitable sustitute for steel 65G and the sufficient efficiency of the chosen enameling technology.

Abstract:
Objectives: This research aimed to characterise the physico-chemical interaction of bioactive glass 45S5 (BAG) air-abrasion with human enamel including the controlled and selective removal of substrates and the remineralisation of enamel white spot lesions (WSLs). Materials and methods: The effect of six operating parameters on air-abrasion dynamic cutting efficiency/patterns was assessed using an enamel analogue material (MacorTM) and white light profilometry. Standardised resin composite restorations created within MacorTM blocks, were removed in simulated clinical conditions and scanned using triangulation laser profilometry to investigate the effect of operating parameters on the selective resin composite removal using BAG air-abrasion. The remineralisation of artificial enamel WSLs treated using BAG mixtures were evaluated using Raman micro-spectroscopy, microhardness and scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectrometry (EDX). The physical and optical changes in WSLs pre-conditioned using air-abrasion with BAG-polyacrylic acid (PAA-BAG) powder were detected using non-contact profilometry and optical coherence tomography (OCT). All comparisons were considered statistically significant if p < 0.05. Results: Significant differences in air-abrasion cutting efficiency / pattern were observed according to the tested parameters. BAG air-abrasion removed resin composite more selectively than conventional alumina air-abrasion and the effect of altering the unit’s operating parameters was significant. Enamel WSLs treated with BAG mixtures exhibited a significantly higher Knoop microhardness compared to the negative control. Raman micro-spectroscopy detected significantly higher phosphate content and the SEM images revealed mineral depositions on the surface of treated lesions. Pre-conditioning WSL surfaces with PAA-BAG air-abrasion increased WSL surface area. This pre-treatment increased Knoop microhardness and the mineral content of remineralised WSLs. Conclusions: The ultraconservative clinical applications of BAG air-abrasion can be improved by altering the operating parameters. BAG and PAA-BAG can remineralise enamel WSLs. Pre-conditioning the lesion surface with PAA-BAG air-abrasion modifies the lesion surface physically and consequently enhances remineralisation using BAG 45S5 therapy.

Magister Scientiae Dentium - MSc(Dent)
Introduction: Micro-leakage and enamel demineralization is still a major challenge in dental practice. It can lead to formation of demineralization lesions around and beneath the adhesive–enamel interface (Mali et al., 2006). Enamel demineralization adjacent to orthodontic brackets is one of the risks associated with orthodontic treatment. The prevention of demineralization during orthodontic treatment is therefore essential for aesthetic reasons and to circumvent the onset of caries. Aim: To assess micro-leakage and enamel demineralization around orthodontic direct attachments (brackets) using three different orthodontic cements. Materials and methods: In this in-vitro study, intact (non carious) extracted human premolars were used to compare the micro-leakage and enamel demineralization of three different cements (Fuji Ortho LC, Rely X luting 2 and Transbond XT). The dye penetration technique was used to evaluate micro-leakage on extracted human premolars. Micro-hardness testing was performed on 21 teeth to determine enamel demineralization. Sixty teeth were randomly divided into 3 groups of twenty teeth each. Direct attachments were cemented on each tooth using 3 different cements; Fuji Ortho LC (GC Fuji II LC GC Corporation Tokyo, Japan), (group 1), Rely X luting 2 cement (3M ESPE dental product, USA), (group 2), Transbond XT Light Cure (3M Unitek, Monrovia, Calif), (group 3). After the orthodontic direct attachments were fitted, they were exposed to 500 thermo-cycles between 5°C and 55°C, with a dwell time of 15 seconds in a buffered (pH 7) 1% methylene blue dye solution (Grobler et al, 2007). The specimens were viewed under a stereomicroscope (Nikon, Japan) at magnification of 40 times. Photographs of each specimen were taken with a Leica camera (Leica DFC 290 micro-systems, Germany) fitted onto a stereomicroscope. The ACDsee photo editing programme was used to transfer the photographs to a computer to measure the dye penetration along the enamel–adhesive and adhesive–bracket interfaces, both on the gingival and occlusal edge at × 40 magnification. For the demineralization sample, 21 teeth were divided into 3 groups of seven teeth each, where direct attachments were cemented using each of the 3 cements, group 1, Fuji Ortho LC (GC Fuji II LC GC Corporation Tokyo, Japan); group 2, Rely X luting 2 cement (3M ESPE dental product, USA) and group 3, Transbond XT Light Cure (3M Unitek, Monrovia, Calif). A digital hardness tester with Vickers diamond indenter (Zwick RoellIndentec (ZHV; Indentec UK) was used to measure surface micro-hardness of enamel before and after attaching the brackets. Ten indentations were made on the enamel surface of each tooth before bonding the brackets with a 300g load applied for 15 seconds to establish the baseline hardness value. After de-bonding the brackets, the hardness was measured again in the same area as mentioned above to determine the degree of enamel demineralization (softening). Result: The result showed statistically significantly lower levels of micro-leakage for Transbond XT (P= <0.001). The amount of micro-leakage on the margins was significantly higher in the gingival portion (P <0.05) as compared with the occlusal margin. Enamel micro-hardness tests before bonding using the three different cements showed that the variances are not significantly different (Chi-squared = 3.051, df = 2, p-value = 0.218). However, the micro-hardness tests done after bonding and thermo-cycling was statistically significantly different (Chi-squared = 13.435, df = 2, p-value = 0.001). Clearly, the Transbond XT group had less hardness, implying greater demineralization than the Fuji Ortho LC and Rely X luting 2 groups. Two sample t-tests show that mean value for the Fuji Ortho and Rely X luting 2 were not significantly different from each other (t = -0.636, df = 12, p-value = 0.537). The mean value for Transbond XT differed significantly from both the other two means: Transbond XT vs Fuji Ortho LC (t = 3.249, df = 6.9, p-value = 0.014). Transbond XT vs Rely X luting 2 (t = 3.493, df = 6.8, p-value = 0.011). Conclusions: This study showed that Fuji Ortho LC and Rely X luting 2 show more micro-leakage than Transbond XT. However Transbond XT had significant lower micro-leakage, less hardness (greater demineralization) than the Fuji Ortho LC and Rely X luting 2. This may have been due to the fluoride release which significantly reduces demineralization. Therefore the Fuji Ortho LC and Rely X luting 2 may be recommended for prevention of demineralization during orthodontic treatment.

Abstract:
Enamel demineralisation or white spot lesions (WSLs) is a risk for all patients undergoing fixed appliance orthodontic treatment (FAOT) with no consensus with regards to prevalence, risk factors, prevention and treatment. Slow-release fluoride glass devices (SRFGDs) have been shown to clinically prevent caries without relying on patient’s compliance, therefore their effectiveness in preventing WSLs during FAOT was investigated. An in-vitro exploratory study investigated fluoride (F) and phosphate (PO4) release from different types of powder from SRFGDs incorporated into a composite resin bonding material. Samples were stored in artificial saliva and assessed with ion chromatography for up to six months. Three types of powder showed high F release to maximise caries prevention and low PO4 release to minimise degradation of powder. A questionnaire was emailed to orthodontists’ members of the British Orthodontic Society. For majority of responders the key factors to the problems related to WSLs are clinical examination, photographs, F, oral hygiene, diet and duration of FAOT. A double-blind, randomised clinical study with orthodontic patients randomly allocated to SRFGDs or placebo devices threaded onto the orthodontic wire was conducted. Cross-polarised digital photographs of the maxillary permanent central and lateral incisors and canines were taken for 63 subjects at the start and for 40 subjects at the end of the study. One examiner assessed photographs for presence and severity of WSLs. Majority of volunteers and the smallest number of refusals lived in the most deprived areas according to the Multiple Deprivation Index. Use of SRFGDs would decrease severity by preventing 2.88 times more teeth compared to use of 225 ppm F mouth-rinse once daily and 1,450 ppmF tooth-paste twice daily. Duration of FAOT and increased gingival index at the start of FAOT increased significantly the risk of developing WSLs. SRFGDs were effective in preventing teeth with WSLs during the course of FAOT.

Abstract:
Enamel damage and demineralisation are common complications associated with fixed orthodontic appliances. In particular, the clean-up of adhesive remnants after debonding is a recognised cause of enamel damage. Furthermore, fixed attachments offer retentive areas for accumulation of cariogenic bacteria leading to enamel demineralisation and formation of white spot lesions (WSLs). Bioactive glasses may be used to remove adhesives, preserving the integrity of the enamel surface, while also having the potential to induce enamel remineralisation, although their efficacy in both respects has received little attention. A systematic review evaluating the remineralisation potential of bioactive glasses was first undertaken. No prospective clinical studies were identified; however, a range of in vitro studies with heterogeneous designs were identified, largely providing encouraging results. A series of glasses was prepared with molar compositions similar to 45S5 (SylcTM; proprietary bioactive glass) but with constant fluoride, reduced silica and increased sodium and phosphate contents. These glasses were characterised in several tests and the most promising selected. This was designed with hardness lower than that of enamel and higher than orthodontic adhesives. Its effectiveness in terms of removal of composite- and glass ionomer- based orthodontic adhesives was evaluated against SylcTM and a tungsten carbide (TC) bur. This novel glass was subsequently used for remineralisation of artificially-induced orthodontic WSLs on extracted human teeth. The novel glass propelled via the air-abrasion system selectively removed adhesives without inducing tangible physical enamel damage compared to SylcTM and the conventional TC bur. It also remineralised WSLs with surface roughness and intensity of light backscattering similar to sound enamel. In addition, mineral deposits were detected on remineralised enamel surfaces; these acted as a protective layer on the enamel surface and improved its hardness. This layer was rich in calcium, phosphate, and fluoride; 19F MAS-NMR, confirmed the formation of fluorapatite. This is particularly beneficial since fluorapatite is more chemically stable than hydroxyapatite and has more resistance to acid attack. Hence, a promising bioactive glass has been developed.

Abstract:
Emaillierte Scheiben finden seit sehr langer Zeit ihre Anwendung im Bauwesen als opake Fassadenpaneele in System- oder vorgehängten, hinterlüfteten Fassaden. Mit Mustern in Form von Punkten, Streifen oder Quadraten wird ein teilweiser Sonnen- beziehungsweise Blendschutz realisiert. Ebenso ist seit langem eine festigkeitsmindernde Wirkung einer solchen Bedruckung auf Glasbauteilen bekannt. Die Gründe dafür sind nicht geklärt, und es existieren mehrere Erklärungsversuche, die ihre Belastbarkeit aber noch nicht bewiesen haben. Ebenso beruhen die Normangaben zu bedruckten, vorgespannten Glasprodukten auf empirischen Untersuchungen ohne weitere wissenschaftliche Basis. Daher wird in dieser Arbeit das Ziel verfolgt, eine in der Fachliteratur genannte mögliche Ursache der Festigkeitsminderung genauer zu untersuchen. Neben einer Bewertung der bereits vorhandenen, wenigen Erklärungsversuche wird die in der Literatur geäußerte und auch durch Versuche im Rahmen von Qualitätskontrollen der Glasveredler berechtigte Annahme der Festigkeitsminderung auf Grund geänderter Temperaturverhältnisse während des Abkühlvorgangs durch die Emailleschicht besonders untersucht. Dieser Annahme wird mit spannungsoptischen Messmethoden und in Bruchversuchen nachgegangen. Mit Streulichtmessungen werden mögliche Veränderungen im Eigenspannungsverlauf über die Glasdicke quantitativ ermittelt. Mit Bruchversuchen in einem modifizierten Doppelring-Biegeversuch können dann unter Ansatz der ermittelten Vorspannung im Glas Rückschlüsse auf mögliche strukturelle Veränderungen der Glasoberfläche beziehungsweise größere Defekte geschlossen werden. Mittels numerischer Simulationen des Vorspannprozesses von bedruckten und unbedruckten Scheiben kann auch die Auswirkung verschiedener thermischer Ausdehnungskoeffizienten genauer bestimmt werden. In praktischen Versuchen kann eine solche mögliche Auswirkung nicht untersucht werden, da die Emaille als Überzugsmaterial als handelsübliches Produkt verwendet und nicht frei konfektioniert wird. Daher können nur die thermischen Ausdehnungskoeffizienten im Versuch berücksichtigt werden, die sich im handelsüblichen Produkt einstellen.

Abstract:
Aim: To investigate the use of fluoride glass slow-release devices (FGSRD) for the prevention of dental erosion of human dental enamel in vitro. Methods: Human teeth (permanent and primary) were used for this study. Enamel slabs were randomly allocated to four study groups: Group 1: 24 permanent enamel slabs with FGSRD, Group 2: 24 permanent enamel slabs with placebo non-FGSRD, Group 3: 20 primary enamel slabs with FGSRD, Group 4: 20 primary enamel slabs with placebo non-FGSRD. The glass slow-release devices were randomised into two groups. Test and placebo groups were coded until the end of the study. The enamel slabs were dipped in a citric acid solution for two minutes five times daily for 28 days and brushed twice a day. This was to create the erosive environment for this in vitro study. The slabs were kept in artificial saliva and stored in an incubator at 37°C. The glass slow-release devices (fluoride and non-fluoride) were present in all containers. The surface profile was measured at baseline using surface profilometry and after 14 and 28 days of the cycling regime. Analysis: Simple t-tests were used to compare the permanent and primary teeth groups with 0.05 as the significance level and an ANOVA t-test with a Bonferroni correction to compare: primary and permanent teeth. Daily fluoride release of the FGSRD’s was measured. Results: For enamel of primary teeth, after 14 days 40% less erosion was observed in the F group which decreased to 31% at the end of the study period, i.e., 28 days. This was highly statistically significant (p < 0.001) at both time points. For permanent enamel, no significant differences were observed (p=0.091). Conclusion: FGSRD’s have great potential for protection of primary human enamel against erosive challenge in addition to a number of other uses.

Abstract:
L’art du verre à la Renaissance était marqué par l’influence des maîtres vénitiens, à l’origine d’un certain nombre d’innovations techniques et stylistiques qui connurent un grand succès dans toute l’Europe. En France, Henri II et Catherine de Médicis firent appel à des verriers vénitiens pour établir une verrerie à proximité du château royal de Saint-Germain-en-Laye. Près de trente ans plus tard, une autre équipe de verriers italiens, cette fois-ci originaire du village d’Altare, fondèrent une verrerie au faubourg Saint-Germain-des-Prés. Le développement de l’industrie verrière en Île-de-France du début du règne de Henri II en 1547 à la fin du règne de Henri IV en 1610 est donc étroitement lié à l’arrivée de verriers italiens qui apportèrent leur style et leur savoir-faire. L’histoire verrière de la région ne se limite cependant pas à l’influence italienne. Deux métiers du verre s’organisèrent à Paris à cette époque : celui des patenôtriers d’émail et de verre et celui des marchands verriers. L’étude des hommes et de leurs compétences a constitué un premier axe de recherche. Le second axe choisi a consisté à étudier la commercialisation et la diffusion des produits de verre en Île-de-France et leur contexte d’utilisation. Le verre prit en effet, au XVIe siècle, une place plus importante sur les tables des Parisiens modestes ou fortunés. Les propriétés de ce matériau particulier étaient adaptées à un certain nombre d’usages. Les verres de la Renaissance se divisaient alors entre verres fonctionnels et verres plus prestigieux, collectionnés pour leur valeur esthétique et décorative. Cette thèse transdisciplinaire s’inscrit dans les domaines de l’histoire, de la culture matérielle, de l’histoire de l’art et des techniques et de l’archéologie
The European Renaissance glass art was deeply influenced by the style and the techniques invented by Venetian glassmakers. Those fashionable glass products were in demand in every European country. In France, king Henri II and queen Catherine de Medici established a glasshouse near the royal palace of Saint-Germain-en-Laye and employed Venetian glassmakers. After the death of the glassworkers, a new glasshouse, ruled by Italian glassmakers from Altare was established at the end of the 16th century, in the faubourg Saint-Germain-des-Prés. The development of the glass industry in Île-de-France from 1547 to 1610 is linked to the style and techniques brought by Italian glassmakers. In addition to the Italian influence, two glass-related professions were created at that time in Paris: the glass bead makers and the glass sellers. The study of men and their skills constitutes one approach of the subject. The second one explores the trade, circulation and uses of glass products. They became, in the 16th century, more and more common in both modest and wealthy Parisian interiors and were used for their particular properties (especially suitable for medical use for example). On the other hand, some glass products, more prestigious and fashionable, were collected for their decorative and aesthetic value

Abstract:
Este estudo in situ avaliou em esmalte bovino desmineralizado, submetido ou não a um desafio cariogênico, os efeitos de um cimento de ionômero de vidro de alta viscosidade (CIVav) e de um selante resinoso, comparativamente a um controle (sem selamento). Doze voluntários usaram dispositivos intrabucais palatinos (DIP) contendo 12 blocos de esmalte bovino desmineralizado, fixados dois a dois para simular uma fissura em V, a qual foi selada com um dos materiais: CIVav (Ketac, Molar Easymix), selante resinoso (Delton) ou controle (sem selamento). Metade dos espécimes foi submetida ao acúmulo de biofilme, recebendo oito aplicações diárias de sacarose a 20% para provocar um desafio cariogênico, além de outras três, de solução de dentifrício fluoretado (1 g : 3 mL), enquanto a outra metade não sofreu acúmulo de biofilme, mas também recebeu o dentifrício. Após 14 dias, foram avaliadas as concentrações de flúor no biofilme e no esmalte, bem como o conteúdo mineral (microdureza em secção longitudinal). Os dados obtidos foram analisados estatisticamente ('alfa'= 5%). O teste Friedman ANOVA revelou que a concentração de flúor no biofilme foi estatisticamente maior com o uso do CIVav, em comparação ao selante resinoso e ao controle. A ANOVA e o teste de Tukey constataram que houve maior concentração de flúor no esmalte associado ao CIVav, sobretudo na ausência de desafio cariogênico, enquanto o selante resinoso e controle foram semelhantes. Em relação ao conteúdo mineral, a ANOVA e o teste de Tukey detectaram diferenças entre os grupos na camada mais superficial do esmalte. Com desafio cariogênico, o conteúdo mineral foi sempre maior no esmalte associado ao CIVav do que naquele associado ao selante resinoso, sendo que o controle apresentou resultados intermediários. Sem o desafio cariogênico, houve uma tendência de um maior conteúdo mineral no grupo controle. Os resultados sugerem que o CIVav, aplicado sobre uma superfície desmineralizada e sob desafio cariogênico, demonstrou um potencial cariostático pela sua capacidade de doar flúor à estrutura e ao biofilme dentários, minimizando os efeitos da desmineralização, mas não melhorou a remineralização.
This in situ study evaluated on demineralized bovine enamel, submitted or not to a cariogenic challenge (dental biofilm), the effects of a high viscosity glass ionomer cement (HV-GIC) and a resin sealant in comparison with a control group (without sealing). Twelve volunteers wore a palatal appliance containing 12 blocks of demineralized bovine enamel mounted (2 by 2) to simulate a fissure in a V shape and sealed with: HV-GIC (Ketac? Molar Easymix), resin sealant (Delton) or maintained with no sealing material (control). Half of specimens was submitted to a cariogenic challenge by dripping a 20% sucrose solution 8 times/day besides a fluoride dentifrice solution (1 g : 3 mL) 3 times/day. The others specimens only received a dentifrice solution. After 14 days, the concentration of fluoride in dental biofilm and enamel was evaluated as well as the mineral content (cross-sectional microhardness) of the enamel. The concentration of fluoride in dental biofilm was higher with HV-GIC (Friedman ANOVA, p<0.05) in comparison with resin sealant and control group. The concentration of loosely-bound fluoride on enamel was significant (ANOVA and Tukey test, p< 0.05) specially without a cariogenic challenge for HVGIC, while it was similar for the resin sealant and control group. Concerning the mineral content, ANOVA and Tukey test (p<0.05) detected differences among the groups on the superficial layers of the enamel. Under the dental biofilm influence the mineral content was always higher on the enamel associated with HV-GIC than with resin sealant and the control group presented intermediary results. Without dental biofilm the control group presented a tendency of a higher mineral content. The results suggest that HV-GIC applied on a demineralized surface and under the dental biofilm influence has shown a cariostatic potential by its ability to give fluoride to the dental structure and biofilm reducing the demineralization effects.

Abstract:
Abstract Cavitation and erosion damage to hydroelectric turbines and pumps can be a major problem. The effectiveness of thermal sprayed cavitation-erosion resistant coatings for hydroelectric turbine and pumps was evaluated. The coatings evaluated were applied using High Velocity Oxyfuel (HVOF) and Plasma Spray systems. Hard facing cobalt based alloys were evaluated on coupons in the laboratory. Testing was performed using a cavitating jet erosion apparatus utilizing an operating pressure of 27.6 MPa. The results were compared to welded 308 stainless steel. Cavitation resistant austenitic stainless steel weld alloys were also evaluated. The results showed that the cavitation rate of the austenitic stainless steel weld alloys were as low as one third of the rate of the 308 stainless steel. The cavitation rate of the thermally sprayed hard facing coatings were more than three times higher than the rate of the 308 stainless steel. CERHAB glass enamel coatings containing 7 wt % wollastonite fibers were successful applied by using two combustion spray processes. The applied CERHAB coatings were successfully annealed using field portable heaters and may have application as a seal coat for thermal spray coatings applied in the field.

Abstract:
Thin film heat transfer gauges have been instrumented onto flexible plastic substrates which can be adhesively bonded to plastic or metal models. These new gauges employ standard analysis techniques to yield the heat flux to the model surface and have significant advantages over gauges fired onto machinable glass or those used with metal models coated with enamel. The main advantage is that the construction of the gauges is predictable and uniform, and thus calibration for thickness and geometric properties is not required. The new gauges have been used to measure the heat transfer to an annular turbine nozzle guide vane in the Oxford University Cold Heat Transfer Tunnel. Engine-representative Mach and Reynolds numbers were employed and the free-stream turbulence intensity at NGV inlet was 13%. The vanes were either precooled or preheated to create a range of different thermal boundary conditions. The gauges were mounted on both perspex and aluminium NGVs and the heat transfer coefficient was obtained from the surface temperature history using either a single layer analysis (for perspex) or double layer (for aluminium) analysis. The surface temperature and heat transfer levels were also measured using rough and polished liquid crystals under similar conditions. The measurements have been compared with computational predictions.

Abstract:
Археологические раскопки 2017 г. выявили культурный слой, относящийся практически ко всем этапам развития Мурома. Особенно ярко представлены горизонты XII-XIII вв. и XVI-XVII вв. Характерный ряд столбовых ям указывает на существование в древнерусский период оборонительного сооружения, ограждавшего наземные постройки. Археологический материал этого периода типичен для древнерусских городов. Выделяются две парные бронзовые миндалевидные пришивные накладки, на щитках которых в технике выемчатой эмали изображен процветший крест. Интересны также железное писало и фрагмент стеклянного бокала с росписью золотом и красной краской. Значительная часть материала, собранного в ходе раскопок, принадлежит периоду XVI-XVII вв. и происходит в основном из большой подпольной ямы наземной жилой постройки. Здесь следует отметить фрагменты впервые встреченной в Муроме турецкой керамики с полихромной подглазурной росписью, изготовленной в г. Изник. The archaeological excavations discovered a cultural layer which relates to almost all stages of the development of the Murom. The horizons of the 12th-13th and the 16th-17th centuries are especially emphatically represented. A characteristic row of postholes indicates the existence of a defensive fence in ancient Russian period. Land-type buildings were located inside it. The finds of this period are typical for ancient Russian cities. We can distinguish two bronze almond-shaped sewing badges with the image of a vine cross. The image was made in the technique of champlevé enamel. An also interesting finds are an iron stylus and a fragment of a glass goblet with gold and red ornament. A significant part of the collected material belongs to the period of the 16th-17th centuries and was found mainly in a large cellar pit of a residential building. Fragments of Turkish pottery with polychrome underglaze painting are most interesting. Such ceramics was found in Murom for the first time.

Abstract:
Abstract Experimental measurements have been carried out with the aim of investigating the residual stresses generated during plasma spray deposition of glass composite coatings. The research shows that the behaviour of these materials is fundamentally different from metals and ceramics. The quench stress in the glass composites can be eliminated by plasma-scanning. This is attributed to their low glass transition temperatures, which enable the stresses to be completely relaxed. The work also shows that the addition of alumina as a second phase allows the expansion mismatch between the coating and the steel substrate to be controlled. Control of the second-phase volume-fraction enables the residual stress in the composite coatings to be reduced to zero. Real-time measurements on deflection and temperature show that the dimensions of the substrate, plasma operating conditions and scanning rate have substantial effects on the temperature profiles within the deposits. Keywords: glass composite coatings, thermal stress, plasma spraying.

Abstract:
Heat transfer is extremely important in glass container production since the physical properties of the glass are greatly affected by temperature. The change of glass properties in the production process needs to be closely monitored and controlled to produce high quality containers. The delivery system, which transports glass from feeder to the blank mold of the IS machine, contains the scoop, trough and deflector. It is the first place in the delivery system that molten glass inside feeder is brought into contact with a much colder environment on the delivery equipment. Recent developments in numerical techniques and computing capabilities enable the 3-dimensional free surface simulation of a gob of molten glass in the delivery system. In this study, a finite element method implemented by the computational fluid dynamics package Polyflow from ANSYS is used to track the large free surface deformations of a glass gob during the transport from the feeder to the blank mold. The capability to apply a user defined function allows the effect of varying heat transfer between the contact surface of gob and delivery equipment to be analyzed. A contact algorithm coupled with a Lagrangian remeshing scheme is applied to detect the interface between the molten glass gob and delivery equipment. The heat transfer profile is further studied by using a Fluent model for the equipment and comparing the resultant temperature profiles with measured field data. Better understanding of the delivery system can help manufacturers improve process control and facilitate equipment adjustment to produce containers with consistent loading that leads to increased productivity and reduced defects.

Abstract:
ANSTO has developed a combination of tailored nuclear waste form chemistries coupled with the use of flexible hot-isostatic pressing processing technology to enable the successful incorporation of problematic nuclear wastes into dense, durable monoliths. This combined package also enables the design of waste forms with waste loadings well in excess of those achievable via baseline melting routes using borosilicate glass, as hot-isostatic pressing is not constrained by factors such as glass viscosity, crystallisation and electrical conductivity. In this paper we will discuss some of our experiences with problematic wastes, namely plutonium wastes, sludges and HLW such as the Idaho calcines.

Abstract:
This research project introduced a novel membrane coating strategy to combat biofouling, which is a major problem for the membrane-based treatment of agricultural and municipal wastewaters. The novelty of the strategy is that the membrane coatings have the unique ability to switch reversibly between passive (antifouling) and active (antimicrobial) fouling control mechanisms. This dual-mode approach differs fundamentally from other coating strategies that rely solely on one mode of fouling control. The research project had two complementary objectives: (1) preparation, characterization, and testing of dual-mode polymer nanolayers on planar surfaces and (2) evaluation of these nanolayers as membrane modifiers. The first objective was designed to provide a fundamental understanding of how polymer nanolayer chemistry and structure affect bacterial deposition and to demonstrate the reversibility of chemical switching. The second objective, which focused on membrane development, characterization, and testing, was designed to demonstrate methods for the production of water treatment membranes that couple passive and active biofouling control mechanisms. Both objectives were attained through synergistic collaboration among the three research groups. Using planar silicon and glass surfaces, we demonstrated using infrared spectroscopy that this new polymer coating can switch reversibly between the anti-fouling, zwitterion mode and an anti-microbial, quaternary amine mode. We showed that switching could be done more than 50 times without loss of activity and that the kinetics for switching from a low fouling zwitterion surface to an antimicrobial quaternary amine surface is practical for use. While a low pH was required for switching in the original polymer, we illustrated that by slightly altering the chemistry, it is possible to adjust the pH at which the switching occurs. A method was developed for applying the new zwitterionic surface chemistry onto polyethersulfone (PES) ultrafiltration membranes. Bacteria deposition studies showed that the new chemistry performed better than other common anti-fouling chemistries. Biofilm studies showed that PESultrafiltration membranes coated with the new chemistry accumulated half the biomass volume as unmodified membranes. Biofilm studies also showed that PES membranes coated with the new chemistry in the anti-microbial mode attained higher biofilm mortality than PES membranes coated with a common, non-switchablezwitterionic polymer. Results from our research are expected to improve membrane performance for the purification of wastewaters prior to use in irrigation. Since reduction in flux due to biofouling is one of the largest costs associated with membrane processes in water treatment, using dual-mode nanolayer coatings that switch between passive and active control of biofouling and enable detachment of attached biofoulants would have significant economic and societal impacts. Specifically, this research program developed and tested advanced ultrafiltration membranes for the treatment of wastewaters. Such membranes could find use in membrane bioreactors treating municipal wastewater, a slightly upgraded version of what presently is used in Israel for irrigation. They also may find use for pretreatment of agricultural wastewaters, e.g., rendering facility wastewater, prior to reverse osmosis for desalination. The need to desalinate such impaired waters water for unlimited agricultural use is likely in the near future.
