We present the design and evaluation of a simple, compact and efficient electromagnetic energy harvesting tile that can be used to harness energy from footsteps. The proposed harvester incorporates a translational–rotational origami-inspired coupling mechanism to transform the axial loads exerted by human footsteps into a localized rotation of an electromagnetic generator. The coupling mechanism employs a non-rigid tunable Kresling spring, the restorative behaviour of which is tunable to maximize energy transduction from the applied load to the generator. A computational model is developed to optimize the design parameters of the mechanism, which are then utilized to fabricate a prototype of the energy harvester. The tile is tested under loading conditions that mimic a human step, where it is demonstrated that it is capable of generating 4.18 W of electrical power per step with a surface power density of 2609 μW cm−2. This article is part of the theme issue 'Origami/Kirigami-inspired structures: from fundamentals to applications'. [ABSTRACT FROM AUTHOR]

Tile and Young-Burgess classification systems have been widely used to classify pelvic ring injuries in clinical settings; however, these two systems are rarely mentioned in the literature despite their reproducibility and practical application. The purpose of this study was to assess the interobserver and intraobserver reliability of the Tile and Young-Burgess classification of pelvic ring injuries. Eight hundred seven patients with pelvic fractures who presented to two I-level trauma centres between January 2016 and June 2020 were recruited for this study. The anteroposterior, inlet, and outlet of the pelvis were observed on radiographic images, and CT scans were performed on each patient. The anteroposterior, inlet, and outlet of the pelvis were radiographed at each visit, and CT scans were performed. Four observers were recruited to classify the injury type according to the Young-Burgess and Tile classification systems. Interobserver and intraobserver reliability (kappa coefficient, κ) were applied to assess the reproducibility of the two classification systems. A total of 174 patients (21.56%) could not be classified with the Young-Burgess classification, and all patients could be classified according to the Tile system. The mean κ value of the interobserver reliability was 0.558 (range, 0.444 to 0.653) for the Tile classification, indicating moderate agreement, whereas the mean κ value was 0.637 (range, 0.560 to 0.713), indicating substantial agreement, when the Young-Burgess classification was used. The mean κ value for intraobserver reliability was 0.597 (range, 0.567 to 0.653) for the Tile classification and 0.776 (range, 0.748 to 0.803) for the Young-Burgess classification. More pelvic ring injuries could be classified with the Tile classification than could be classified with the Young-Burgess classification. However, the reproducibility of the Young-Burgess classification was greater than that of the Tile classification. [ABSTRACT FROM AUTHOR]

Raster data represent one of the fundamental data formats utilized in GIS. As the technology used to observe the Earth continues to evolve, the spatial and temporal resolution of raster data is becoming increasingly refined, while the data scale is expanding. One of the key issues in the development of GIS technology is to determine how to make large-scale raster data better to provide computation, visualization, and analysis services in the Internet environment. This paper proposes a decentralized COG-pyramid-based map service method (DCPMS). In comparison to traditional raster data online service technology, such as GIS servers and static tiles, DCPMS employs virtual mapping to reduce data storage costs and combines tile technology with a cloud-native storage scheme to enhance the concurrency of supportable requests. Furthermore, the band calculation process is shifted to the client, thereby effectively resolving the issue of efficient customized band calculation and data rendering in the context of a large-scale raster data online service. The results indicate DCPMS delivers commendable performance. Its decentralized architecture significantly enhances performance in high concurrency scenarios. With a thousand concurrent requests, the response time of DCPMS is reduced by 74% compared to the GIS server. Moreover, this service exhibits considerable strengths in data preprocessing and storage, suggesting a novel pathway for future technical improvement of large-scale raster data map services.

In this study, technical properties of 3 different clays from Doğanhisar/Konya region were determined to investigate their usage potential in glazed porcelain tile production of Yurtbay Seramik Company. For this purpose, mineralogical, chemical, and thermal characterization of the clays was performed using XRD, XRF, and dilatometric analyses. Furthermore, the use of Konya clays instead of Ukrainian clay in the porcelain tile compositions was studied. Ukrainian clay was substituted gradually by Konya clays in different tile body recipes. Samples, having these new compositions, were prepared by uniaxial pressing, and exposing to a firing regime at 1190 °C for 55 min. Fired samples were then characterized based on their dry strength, fired strength, water absorption, color, and firing shrinkage properties. Experimental results proved that the use of Konya clays instead of Ukrainian clay increased the strength of fired bodies. It would be possible to use Konya clays in tile bodies up to 6 wt.% with some modifications in the body compositions and firing regime. [ABSTRACT FROM AUTHOR]

The effect of ZrO 2 and TiO 2 addition in gahnite-based glass-ceramic glazes was investigated by equimolar nucleating agents substituting 5 mol% SiO 2. The effect of this substitution on thermal behavior was studied by means of differential thermal analysis and hot stage microscopy. The sintering behavior of samples changed with the type of nucleating agent added. Compacted samples sintered between 850 and 1200 °C for 2 min at 40°Cmin−1 heating and cooling rate for determining the crystallization sequence with using X-ray diffraction. Prepared glaze samples fired at 1180 °C for 6 min in the industrial roller kiln. Total firing time is 58 min from cold to cold. The effect of nucleating agent additions of gahnite-based glass-ceramic glazes was investigated by X-ray diffraction, scanning electron microscopy, spectrophotometer, and gloss meter. Glaze without nucleating agents shows heterogeneous surface crystallization from the frit surface to the inside with dendritic gahnite growth. With the nucleating agent, volume crystallization was seen with phase separation or seeding effect, which depends on the type of nucleating agent. Glaze with TiO 2 has two different morphology; one region has fine gahnite crystals below 100 nm, and another region has clusters of nano gahnite crystals in flake-like morphology. ZrO 2 provides fine gahnite crystallization, which is smaller than 80 nm. While ZrO 2 added glaze is translucent, the other glazes are opaque due to different crystal sizes. It is observed that nano crystallization has a positive effect on pore swelling behavior due to its high crystal surface area. With the addition of the ZrO 2 and TiO 2 , fine-sized nanocrystalline gahnite based glass-ceramic glazes can be obtained for the first time in industrial fast-firing conditions.

In this study, the focus is directed towards terracotta building materials with "traces," which were disregarded as defective and unworthy of consideration until recently. Samples have been examined through the lens of ichnoarchaeology, revealing that every material unearthed has the potential to provide information about the past, support existing theories, or facilitate novel interpretations. A total of fifty-three samples from two ancient cities were analyzed in this study. The findings of this research support the scholars' thesis that the climatic conditions in Anatolia in the 2nd century AD were similar to those of today. Moreover, it was concluded that the environment surrounding the brick workshop in Aizanoi was markedly more severe compared to that of Perge. The examined traces also enabled certain evaluations concerning social life during the Ancient Period. [ABSTRACT FROM AUTHOR]

Based on Zong's work [26] on translative packing densities of 3-dimensional convex bodies, we present a local method to estimate the density θt(C3) of the densest translative covering of an octahedron. As a consequence we prove that θt(C3) ≥ 1 + 6.6 × 10–8, which is the first non-trivial lower bound for this density. [ABSTRACT FROM AUTHOR]

Fuglede's conjecture states that a subset Ω ⊆ R n with positive and finite Lebesgue measure is a spectral set if and only if it tiles R n by translation. However, this conjecture does not hold in both directions for R n , n ≥ 3 . While the conjecture remains unsolved in R and R 2 , cyclic groups are instrumental in its study within R . This paper introduces a new tool to study spectral sets in cyclic groups and, in particular, proves that Fuglede's conjecture holds in Z p n q r . [ABSTRACT FROM AUTHOR]

In the absence of significant excavations, the roofing materials remain poorly known in the Massif Central. Textual sources, such as iconographic images, partly answer the questions, as do the many surveys, and chance discoveries. These weaknesses encourage precise monitoring of the restoration sites: attic, kidneys of the vaults, reuse. Only a broad survey helps to get a correct idea of these materials and their devices.

The Prairie Pothole Region, which extends from north-central Iowa northward into Canada and westward to Montana, is typified by closed depressions that formed over 10,000 years ago during the most recent glacial retreat. Today, many of these potholes contain artificial drainage to lower the water table, allowing for agricultural production of the land. Even when drained, farmed potholes can become inundated with phosphorus (P) enriched surface waters after large rain events. The goal of this study was to characterize the spatial distribution of soil P in farmed potholes and evaluate a steel media-modified blind inlet as a tool to reduce P export from farmed potholes. Results from the soil sampling indicated that Bray-1 soil test P concentrations are nine times higher near the bottom of the pothole compared to locations outside of the farmed pothole. Steel shavings were evaluated for P sorption in a laboratory flow-through cell evaluation where they removed between 60 and 70% (discrete P), even when cumulative P loading was over 6000 mg kg-1. In a field investigation, a modified blind inlet containing a mixture of steel shavings and pea gravel replaced a Hickenbottom surface intake. The modified blind inlet retained an average of 83% of the influent dissolved reactive P and 62% of the influent total P based on five paired samples. The results from this study demonstrate that farmed potholes contain a significant amount of legacy soil P and that blind inlets containing steel shavings can replace surface intakes and reduce P export from farmed potholes. This research could inform future design and implementation of these P removal structures. [ABSTRACT FROM AUTHOR]

• Comprehensive study of an alleged forgery of a tempera painting on tile with apparently Botticelli features. • Pigments identification – i.e., iron oxide pigments, cinnabar, carbon black, and calcite) - by combined FORS and Raman spectroscopy. • Pigments mapping by SCM algorithm application to the multispectral image cube. • Colorimetric analysis to quantitatively evaluate the cleaning method and provide support for an informed restoration process. In this work, a tempera painting of uncertain attribution from the Uffizi Galleries was studied. The painting, which portraits a man with apparently Botticellian features, was probably created by one of the most skilled forgers of the early 20th century, Umberto Giunti. He used a flat tile as a support, covered with preparatory layers emulating a wall painting. To shed light on the authorship of the painting, it was crucial to investigate its composing materials, as well as the execution technique and the state of conservation. To this end, non-invasive spectroscopic and imaging optical techniques were applied. Specifically, VIS-NIR multispectral reflectography was used to reveal the presence of possible preparatory drawings, pentimenti and overpaintings. Raman and Fibre Optics Reflectance Spectroscopies allowed identifying the pigments used by the artist. Finally, colour variations due to the cleaning procedure were documented in order to provide a support for an informed restoration process. [ABSTRACT FROM AUTHOR]

Mihrabs, which are the most important elements of the interior of religious buildings, are called cells that show the direction of qibla to turn during prayer in mosques and masjids. Mihrabs differ in terms of materials, forms, techniques and ornamental features, considering the period in which they were built and regional characteristics. Especially in Islamic architecture, it is a tradition to decorate the mihrab and the mihrab wall, and it is possible to see different materials such as stone, plaster, tile, brick and wood as decoration elements. The applications of tile decoration on altars, which has an important history, go back to ancient times, and we see examples where different techniques and compositions are used on tiled altars. It is seen that tiles in the underglaze technique produced in Iznik and Kütahya were used extensively in Ottoman architecture. It is understood that these tiles have been preferred especially in the decoration of mihrabs since the 16th century, and similar practices continued in the 17th century. In the 18th century, examples of underglaze tiles produced in the Tekfur Palace workshop can be seen on mihrabs. In the 18th century, known as the Tulip Era, Grand Vizier Nevşehirli Damat İbrahim Pasha wanted to revive Iznik tile making and decided to establish a tile workshop near Tekfur Palace, which is a part of the Blakhernai Palace complex, an old Byzantine structure in the Eyüp district of Istanbul. It is understood from the edicts that the Iznik judge requested the tile masters, materials and plans of the kilns to be sent to work in the workshop for tile production. In the studies, information was given about the Tekfur Palace tile workshop, and the technical, motif and composition features of the tiles were discussed in general terms. No in-depth research has been conducted on the Tekfur Palace-made tiles seen on the mihrabs of Ottoman mosques. Our aim is to examine and evaluate the layout of the tiles produced in Tekfur Palace on the mihrabs and their color, motif and composition features. [ABSTRACT FROM AUTHOR]

The authors present the latest information obtained during the archaeological research of the central mausoleum of the Golden Horde memorial complex, located near the village Lapas of the Astrakhan region. Within the scientific circle, the complex of mausoleums is associated with the burial place of the Juchid khans and representatives of the Golden Horde elite. The article gives a detailed description of the building material and architectural decoration used in the construction of the mausoleum. The analysis of the obtained samples of bricks and tiles allows us to propose their classification and typology based on the use of various materials and manufacturing techniques. The connection with architectural traditions and construction techniques of medieval Khorezm is traced. Based on the preliminary analysis, the prospects for further study of the construction technologies used in the creation of this unique architectural complex are outlined.

Unstable U-shaped sacral fractures and vertical shear Tile C pelvic ring disruptions are characterized by rare lesions occurring in patients with severe trauma. Because the initial damage-control resuscitation primarily aims to stop life-threatening bleeding, emergency treatment often includes an anterior external pelvic fixator. Delayed surgery is mandatory to allow early mobilization, reduce mortality, and improve functional outcomes. Regarding U-shaped sacral fractures, although Roy-Camille type 1 U-shaped sacral fractures can be treated with iliosacral screws, types 2 (posteriorly displaced, equivalent to AO Spine C3) and 3 (anteriorly displaced, equivalent to AO Spine C3) fractures require spinopelvic triangular fixation. Besides, proper reduction of type 2 and some type 3 sacral fractures is mandatory to prevent wound complications. In patients with neurological deficits, the need for sacral laminectomy is left at the discretion of the surgeon, given the indirect decompression already obtained with fracture reduction. Tile C pelvic disruptions with posterior ring injury located lateral to the sacral foramen can be treated with either iliosacral screws or triangular spinopelvic fixation, combined with anterior pelvic fixation. Conversely, Tile C pelvic disruptions with posterior ring injury located at, or medial, to the sacral foramen (Denis zone II or III) induce vertical lumbosacral instability and thus require spinopelvic triangular fixation with anterior pelvic osteosynthesis. Although minimally invasive techniques have been developed, open surgeries are still required for inexperienced operators and in case of major displacement. The complication rate reaches approximately 33.33% of the cases, and complications include hardware malposition, wound infection or dehiscence, hardware prominence, and sometimes hardware failure.

Abstract Micronized zircon (ZrSiO4) is used as an opacifier in the production of engobes, opaque glazes, and floor tile bodies. Elevated price levels incentivize researchers to develop alternative engobe formulations with reduced zircon ratios. In this study, new engobes with low zircon content were developed with varying SiO2-Al2O3 mixtures. The effect of the SiO2/Al2O3 ratio on the performance and opacity of the wall and floor tile engobes was investigated. It has been observed that the amount of zircon in the sample compositions could be reduced up to 40% by optimizing the refractoriness-water absorption balance of the engobe with the SiO2/Al2O3 ratio while keeping the opacity in the preferred levels. The color difference (∆E) value relative to the standard surface was below 1, which is acceptable for visual perception for all the samples. Other measurements such as water absorption and firing shrinkage of the floor tile samples were found to be compatible with the standard composition.

In medieval Alsace, three main types of roofing materials were used in various forms and at the same time: thatch, wood and terracotta. The present contribution aims to provide an overview of the use of each of these materials. The period under consideration, from the 12th to the 16th century, is marked by several major developments, which are by no means linear in chronological and geographical terms: 1o the reappearance in the 12th-13th centuries of terracotta roofing in a landscape that had until then been largely dominated, as far as can be perceived, by thatch and wood roofing; 2o the development of the production of hollow hooked tiles, which became a permanent fixture in towns from the 14th-15th centuries onwards, to the detriment of other roofing materials; 3o a contrario, the continuation in thatched and wooden roofs in rural contexts, village and castles, far beyond the Middle Ages; 4o the appearance and unprecedented development, in the first half of the 16th century, of flat roofing tiles (to the detriment of the old hollow tiles whose production became marginal). The demonstration, based in particular on data from excavations and archaeological studies of the building, but also on the use of written and iconographic sources, will seek to specify the chronological stages of these developments and to determine the reasons for these changes.

Environmental and public health problems have been linked to the accumulation of waste products from a variety of industrial and energy production operations. The way that trash is recycled is where ceramics really stand out. Research is being conducted to determine whether or not “certain wastes and industrial by-products, such as fly ash (FA), rice husk ash (RHA), blast furnace slag (BFS), sludge, glass waste, polished tile waste, eggshell, textiles and others, might be used in the production of ceramics. According to the findings of the research, there is a great possibility for the ceramic sector to use wastes as a substitute for natural raw materials in the production process. Converting waste products into valuable ceramics is an environmentally responsible solution to address problems associated with waste management.

Purpose: The purpose of this study was to analyze the patient/injury characteristics and associated hospital course of patients sustaining traumatic pelvic ring injuries after alpine ski and snowboard accidents at a level one trauma center in the Rocky Mountain region. Methods: Patient/injury characteristics were obtained from patients presenting with pelvic ring injuries after alpine ski (n = 55) and snowboard (n = 9) accidents. Characteristics and outcomes analyzed included mechanism of injury, pelvic ring classification (Young–Burgess and Tile), hospital admission, physical therapy (PT) clearance, ambulation, length of stay, inpatient morphine milligram equivalents (MME), and discharges to rehabilitation facility. Results: Snowboarders were more often younger, male, tobacco/substance users, and more likely to be injured by a fall from height than skiers. There were no differences in injury classification or hospital course outcomes between alpine sports. Most common injuries included lateral compression type 1 (LC1) injuries (37.5%), isolated pubic ramus fractures (31.3%), and isolated iliac wing fractures (15.6%). LC1 injuries were unstable in 50% of cases and associated with increased admissions (proportional difference: 47.5%, CI: 23.8–64.5%, p = 0.0002), longer time to PT clearance (median difference(MD): 1.0 day, CI: 0–2.0, p = 0.03), longer LOS (MD: 2.0, CI: 0–2.0, p = 0.02), and increased inpatient MMEs (MD: 197.9 MME, CI: 30.0–420.0, p = 0.02), as compared to other pelvic ring injuries. Conclusion: The majority of pelvic ring injuries from alpine ski and snowboard accidents were LC1 injuries, half of which were unstable, resulting in longer hospital stays, time to PT clearance/ambulation, and opioid use.

Large-scale environmental problems have been triggered by ceramic tiles from demolished buildings and animal bone waste. Therefore, optimizing their potential for reuse and recycling is an important goal of sustainable solid waste management. The primary objective of this study is to evaluate the feasibility of partial replacement of the fine aggregates in cement mortar with a combination of natural animal bone powder and industrial waste materials which is wall tiles ceramic powder. This study measures thermal and mechanical characteristics. Recycling construction waste is one of many ways to deny waste material from entering landfills and create new eco-friendly material that reduces energy consumption in buildings. Modified mortar cement specimens with 5% up to 25% mixtures were combined using a 1:3 ratio and a 0.5 W/C ratio to see how the ratios would affect the material's properties. The addition of a superplasticizer boosted the cement mortar's workability and compressive strength. The compressive strength, flexural strength, density, and thermal conductivity were evaluated for each mortar mixture ratio. Results showed that compared to regular cement mortar, cement mortar combined with 20% bone and ceramic powder wastes reached the optimal replacement percentage. Compressive strength increased by 54% and flexural strength by about 67%. At the 28-day mark, thermal insulation was lowered by 25%.It is concluded from this study that it is possible to use bone waste as a natural material with ceramic waste as an industrial material to modify the insulation and mechanical properties of cement mortar.

Tile is one of the most important building materials. Tile has the main function as a roof covering. Tile is more often used in the construction of houses. The tile protects the occupants of the house from the hot sun and rain. Selection of the right tile needs to be considered for the comfort of the occupants of the house. In this study, the determining factors in the selection of roof tiles are price, product quality, and product availability. The types of tiles used in this research are ceramic tiles, clay tiles, Alderon tiles, asbestos tiles, zinc tiles, and metal roof tiles. The method used in this study is the multidimensional scaling method. The multidimensional scaling method is one of the multivariate analysis methods used to determine the similarity value based on the proximity seen on the perceptual map. Based on the calculation results, it is determined that the types of tiles that have similarities are ceramic tiles and Alderon tiles with a distance value of 0.2062. Furthermore, the best roof tiles based on respondents' perceptions are Asbestos tiles because the variables of product quality and product availability have advantages

Abstract This study presents archaeometric analyses of glazed tiles produced with the cut-mosaic technique to reveal information about the Anatolian Seljuk period’s architecture and ceramic technology. The Persian Seljuk artists also used the same technique. For this purpose, physical, chemical, thermal, mineralogical, microstructural, and molecular analyses were carried out on the tiles from the Seljuk period unearthed in the Kılıçarslan Square excavation in Konya, the capital of the Anatolian Seljuk State from the twelfth-century to the beginning of the fourteenth-century. SEM, XRD, and Heat Microscopy analyses showed that the Seljuk period tiles were not fired at high temperatures like today’s tiles and were probably fired at temperatures below 1100 °C. WD-XRF analyses revealed that the glazes are classified into two categories, one being alkali varying the content of Na2O + K2O between 13 and 16 wt% (PbO between 0.5 and 2 wt%) and the other being lead-alkali type in which PbO content varies between 13 and 15 wt% and alkali content 10–14 wt%. The cobalt content in the blue color is around 0.2 wt%, and copper content in the turquoise-colored samples varies between 2.9 and 4.4 wt% depending on the lightness and darkness of the color (higher amount for tile 1 and tile 3, which are darker than the others). The brown color is obtained by the presence of MnO (3.3 wt%). Raman analysis showed that the difference in sintering temperature caused the color tone difference in Seljuk period tiles, and glazes were formed in the range of 800–1000 °C depending on the Ip values.

Fuglede's conjecture states that for a subset Ω of a locally compact abelian group G with positive and finite Haar measure, there exists a subset of the dual group of G which is an orthogonal basis of L² (Ω) if and only if it tiles the group by translations. In this paper, we prove a divisibility property for a set in Zp × Zpn. Then, using the divisibility property and equidistribution property, we prove that Fuglede's conjecture holds in the group Zp × Zpn. [ABSTRACT FROM AUTHOR]

Fuglede's conjecture states that for a subset Ω of a locally compact abelian group G with positive and finite Haar measure, there exists a subset of the dual group of G which is an orthogonal basis of L² (Ω) if and only if it tiles the group by translations. In this paper, we prove a divisibility property for a set in Zp × Zpn. Then, using the divisibility property and equidistribution property, we prove that Fuglede's conjecture holds in the group Zp × Zpn. [ABSTRACT FROM AUTHOR]

Roof tile sector in Turkey is continuing to develop every day and traditional production methods are replaced by processes evaluated via R&D studies. Accordingly, bigot and new recipe studies have been conducted at Ece Kiremit production facilities for the identification and elimination of drying cracks during natural drying following the shaping of roof tile products. Bigot Curves were drawn for all raw materials in addition to conducting studies for drawing out their characterizations as well as studies for new recipes for eliminating these faults. Based on the Bigot Curve logic, drying curves were drawn for all samples at 100 °C to identify the moisture release characteristics of roof tile samples as well as their drying shrinkage and curves were provided for shrinkage - moisture based on Bigot. As a result of the experimental studies conducted, three different clays were used in the study including Gülücek Clay, Gülücek Kist and Kınık Kist. It was analyzed that since Gülücek Kist has a lower dry shrinkage compared to the other raw materials and since it completes its dry shrinkage upon releasing a small portion (1,04 %) of its moisture, using it in high amounts in the recipe will lead to drying cracks. In addition, as can be understood from the results of characterization analyses, it was observed to have a greater water retention capacity compared with the other raw materials since it has a structure that includes minerals such as chlorite and clinochlore. A total of 4 different recipes were developed and the ratio of Gülücek Kist was decreased in the recipe. It can be observed for all 4 recipes that drying shrinkages are at a wider interval based on time but that the moisture is released faster. Recipes 3 and 4 were considered to have priority for production trials and it was considered appropriate to conduct production trial with recipe 2 in case any adverse results are obtained.

The new Muslim Turkish states that emerged with Turks' entry into the Islamic field brought their culture to Islamic civilization. Turks reflected their own Islamic perceptions and lives onto the works they produced in the architectural, literary, cultural, and artistic fields. The reason why Persian poetry evolved and moved to a higher point during the Great Seljuk State was that the sultans and high-level bureaucrats were patrons of poems and poets. In the same period, the firing techniques used in tile art were further developed by the masters of the city of Kashan, and the tile products the city produced began to be called kāshī. In the 13th and 14th centuries, quatrains adorned these tiles, which were described as luxury consumer goods of the period. This article examines this period of time where poetry and tile work occurred hand in hand and the importance of the city of Kashan as a tile production center and presents the place and development of quatrains that began developing in the Great Seljuk period with regard to the sultans and society. The article then examines the poems found on various ceramic products belonging to the 13th and 14th centuries, presents their translations, and shares pictures of these tiles in order to identify the poets and form an opinion on the poetry and aesthetic tastes of period.

The Masjed-e Jāme' of Isfahan is one of the largest historic mosques in the Islamic world. It was listed as a World Heritage Site by UNESCO. Due to the arid climate of the region, the building is quite well preserved and presents only localized patterns of alteration. However, due to the risk of biodeteriogenic microorganisms which could be present on these valuable surfaces, this study aimed to isolate the microorganisms associated with the specific deteriorated areas of this monument and determine their deteriorative mechanism. Samples were taken from the deteriorated areas in order to isolate bacteria and fungi. These were tested for their potential to induce biodeterioration via CaCO3 dissolution, pH alteration, and pigment and mineral production. Results revealed that ubiquitous species such as Penicillium spp. and Bacillus spp. were the most abundant microorganisms isolated from the samples, some of which were able to release organic acids and induce CaCO3 dissolution. Very often, the isolated fungi showed a combined biodeteriogenic activity due to solubilization and precipitation of CaCO3. Rarely was CaCO3 solubilization combined with pigment release. These findings are a first step toward providing helpful information to assess the biodeteriogenic potential of colonizing microorganisms and planning a preventive method for the conservation of this monument which has never been studied in terms of biodeterioration risk.

Ceilings, windows, and wall tiles were installed in a 3-story reinforced concrete structure subjected to shake-table tests. Alternative detailing for each type was used to evaluate their impact on seismic performance. The ceiling built using conventional detailing had no catastrophic damage but incurred crushing of plasterboards, creating a gap between the ceiling and the surrounding beams. For sliding windows, damage which could cause injuries was not observed, whereas glass cracking was observed for fixed windows. For tiles, the use of organic adhesive prevented tiles from falling, compared to the use of mortar where tile spalling was observed. [ABSTRACT FROM AUTHOR]

Due to the little variation in defect points, tile block defect detection typically detects subtle defects in large-format images, allowing defective characteristics to be displayed regionally. Traditional convolutional neural network architectures that extract regional features take into account the connection between regional features simply, resulting in the presence of region-specific bias, which makes tile block defect detection still a challenging task. To address this challenge, this paper divides feature information into patches that can represent different regional features. Additionally, the relationship between different patches and tile block defects is studied; as a result, this paper proposes a new attention mechanism called the Cross Patch Attention Module (CPAM). Since the regional performance of patches is consistent with the tile block defect characteristics, CPAM can distinguish various regional features by patches. Then, in order to create reliable one-dimensional patch information, CPAM provides a method to connect patches linearly in two spatial directions. This takes into account the correlation of adjacent patches in various spatial directions. Finally, by extracting the regional characteristics of patches, CPAM can successfully assist the model in distinguishing the importance of different patches. The experimental results demonstrate that CPAM has excellent performance for tile block defect detection, and plugging CPAM into different end-to-end models can have a good gain effect, which can effectively and stably help the model to complete the task of tile block defect detection.

This study presents archaeometric analyses of glazed tiles produced with the cut-mosaic technique to reveal information about the Anatolian Seljuk period's architecture and ceramic technology. The Persian Seljuk artists also used the same technique. For this purpose, physical, chemical, thermal, mineralogical, microstructural, and molecular analyses were carried out on the tiles from the Seljuk period unearthed in the Kılıçarslan Square excavation in Konya, the capital of the Anatolian Seljuk State from the twelfth-century to the beginning of the fourteenth-century. SEM, XRD, and Heat Microscopy analyses showed that the Seljuk period tiles were not fired at high temperatures like today's tiles and were probably fired at temperatures below 1100 °C. WD-XRF analyses revealed that the glazes are classified into two categories, one being alkali varying the content of Na2O + K2O between 13 and 16 wt% (PbO between 0.5 and 2 wt%) and the other being lead-alkali type in which PbO content varies between 13 and 15 wt% and alkali content 10–14 wt%. The cobalt content in the blue color is around 0.2 wt%, and copper content in the turquoise-colored samples varies between 2.9 and 4.4 wt% depending on the lightness and darkness of the color (higher amount for tile 1 and tile 3, which are darker than the others). The brown color is obtained by the presence of MnO (3.3 wt%). Raman analysis showed that the difference in sintering temperature caused the color tone difference in Seljuk period tiles, and glazes were formed in the range of 800–1000 °C depending on the Ip values.

The tile-spectral direction of the discrete Fuglede-conjecture is well-known for cyclic groups of square-free order, initiated by Łaba and Meyerowitz, but the spectral-tile direction is far from being well-understood. The product of at most three primes as the order of the cyclic group was studied intensely in the last couple of years. In this paper we study the case when the order of the cyclic group is the product of four different primes and prove that Fuglede’s conjecture holds in this case. [ABSTRACT FROM AUTHOR]

This paper focuses on developing a strategy to represent a new Fibonacci identity using James abacus. The idea of a Graphical chain with respect to the beta numbers and abacus was established to count the number of ways to tile a James diagram chain inscribed infinite grid. Then, the idea of chain abacus and beta numbers were used to find new identities of Fibonacci numbers.
