The paper presents a study of chapel typology on the example of Novosibirsk and Tomsk regions. The analysis of existing chapels includes their architectural style, attachment to other buildings, roofing, the number of domes, construction materials, functional purpose and temperature conditions. Based on the analysis, the existing typological table of chapels is revised and amended. Studies show that despite the strong influence of the traditional approach to Orthodox architecture, innovative small churches are being built.

Abstract The Syriac poetry of the 11th–14th centuries (so-called Syriac Renaissance) was studied very purely until quite recently. One of the reasons for such indifference is a traditional approach of the scholars, who treated this poetry as a secondary one, because of a strong influence of the Islamic literature. In this article, it is argued that the authors of this period were trying to connect their own poetical traditions with the achievements of the Persian and Arabic poetry. As the result, they created new original forms that need to be carefully examined. One of the creators of this new style was probably Bar ʿEbrōyō (1226–1286), a famous West-Syrian philosopher and scientist. His esthetic approach was developed by his East-Syrian contemporary Khāmīs bar Qardaḥē of Arbela, who used sophisticated rhythmic and rhyme schemes to achieve a stronger expressive effect. The article discusses one of his poems that demonstrates his outstanding skills as a poet experimentalist in both rhythm and rhyming.

The structure and phase composition of chromium-alloy coatings consisting of the following phases are investigated in the work: when boron doping the coating on brass C68700 consists of phases: Cu3Al, CuB, CuZn2 and zones of solid solution Cr, Al, B in copper; during titanium doping Cu3Al and CuAl phases in the transition zone: phases CuTi and CuTi2 When tested on A572 steels, in conditions of sliding friction, the best wear resistance among the considered protective coatings are doped with titanium and boron. Their wear resistance is 1,8 – 2,1 times higher than that of coatings obtained under isothermal conditions. Under non-stationary temperature conditions, the microhardness reaches the following values: when doped with boron H100 = 16500 – 17500 MPa, when doped with silicon H100 = 13500 – 14500 MPa, when doped with titanium H100 = 15000 – 16000 MPa. The obtained results correlate with the indicators of wear resistance. A comparative analysis of the corrosion resistance of protective coatings obtained under non-stationary temperature conditions and isothermal conditions shows that they have a weight loss of 1.7–2.1 times less. It was found that when tested in a 30% aqueous solution of sulfuric acid, all protective coatings have good stability. Thus, when doped with boron, the weight loss is 15,2 g/m2, при when doped with silicon - 10,8 g/m2,  and when doped with titanium - – 9,9 g/m2.

Tribal community and their association with nature is deeply rooted. The primitive tribes in India and the world are settled around forests or islands and use their products for their livelihood. The style of architecture, art, culture, beliefs, socio-economic framework is guided by the local environment. As the primitive tribe remain secluded from the urban development and advancement, their beliefs and practices are limited and are based on real time experiences. The availability of resources around the community shapes the type of architectural and cultural practices of the tribe. The forest provides ample resources like wood, fodder, mud, straw, etc. which serves as construction materials, fuel, and source of livelihood for the ethnic community. The article throws light on the influence of forests and its resourceson the vernacular architectural style, the settlement pattern, dwelling units, construction technology and, materials which ultimately responds to the local climate, art, culture, socio-economic framework, and beliefs of the people.

The analysis of the modern approach to the choice of technological processes of production of heavy concrete products and its weaknesses were shown. It is proved that the technological process as an object is a weekly structured system due to the large degree of uncertainty associated with the human factor. It is established that development of new assortment approach to the choice of technological process of the production of construction materials differing in alleged accounting of functional purpose and service conditions of building constructions in a real estate object can be one version of the solution of this problem. The concept of the choice of optimum technological processes of production of construction materials distinctive in alleged accounting of functional purpose and service conditions of building constructions of real estate objects is developed. The technologies of mathematical statement and the solution of problems of optimization of technological processes of production of the range of construction materials differing in increase in degree of structure of system liaisons with external subsystems on the basis of standard mechanisms of the subject focused accounting of functional purpose and service conditions of building constructions and also standard algorithms of search of optimal solutions for defined the range are developed. Assessment of efficiency of assortment approach to a problem of optimization of technological processes of production of the range of construction materials including comparison of the characteristics of material received as a result of use of modern approach, assortment approach in the set parameters of management and assortment approach with expansion of a set of essential alternatives of technological process of production of the range of construction materials is executed. This assessment has shown that more perspective alternatives on qualitative content of characteristics of material are outside area of normative requirements and need justification.

Bartolomeo Ammannati [Ammanati] (b. 1511–d. 1592) was a prominent sculptor and architect working in Florence in the mid- to late 16th century. He is considered a key figure of the Italian Mannerist period. One of many artists working in the wake of Michelangelo Buonarroti, Ammannati began as a pupil of Baccio Bandinelli before working under Jacopo Sansovino and Giovanni Angelo Montorsoli. Ammannati developed a style that drew on the dynamic compositions of Michelangelo but one that was tempered with a sense of restraint and an ability to engage bold classical forms and details. In the 1530s and 1540s, Ammannati worked on significant projects, such as Sansovino’s Biblioteca Marciana in Venice and Montorsoli’s tomb for the poet Jacopo Sannazaro installed in Naples. However, he encountered a frustrating setback when his tomb for the soldier Mario Nari in SS. Annunziata in Florence was criticized and taken down amidst religious objections. Between 1544 and 1548, Ammannati created remarkable sculptural and architectural ensembles in Padua for humanist and antiquarian Marco Mantua Benavides, including a triumphal arch, statues of Jupiter and Apollo and a colossus of Hercules, whose towering twenty-nine-foot figure was reproduced on a print by Enea Vico and Antonio Lafreri (1553). Ammannati’s tomb for Benavides in the Church of the Eremitani is celebrated for its sculptural and architectural balance, illustrating his take on Michelangelo’s unfinished wall tombs in the Medici Chapel. In 1550, Ammannati married Laura Battiferra of Urbino, an accomplished poet and a prominent figure in the devotional culture of Counter-Reformation Italy. He traveled to Rome where he undertook important commissions related to the papal family, including tombs for the Del Monte in S. Pietro in Montorio and portions of Julius III’s Villa Giulia, on which he collaborated with Giorgio Vasari and Jacopo Vignola. Ammannati’s elegant and whimsical Nymphaeum for the Villa Giulia showcases his developing architectural style. In 1555, Ammannati returned to Florence to serve under Duke Cosimo I de’ Medici, where his service to this family would mark the height of his career and see the full maturity of his style. His works exemplify Mannerism at its height, from the artfully elongated bronzes of the Neptune Fountain to the playful rustication of the Palazzo Pitti courtyard. His numerous fountains present splendid and witty tableaux, and his bronze Ops for the Studiolo of Francesco de’ Medici stands out for its grace and refinement. As architect and engineer, he was responsible for landmarks such as the Ponte Santa Trinità and the Column of Justice, and he oversaw construction materials for the Cathedral and the Uffizi. In his later years, Ammannati took on architectural projects outside of Florence and he grew increasingly dedicated to the Jesuit order and the concerns of the Counter Reformation, even condemning the display of nudity in his own work in 1582. He and Laura left their possessions to the Jesuits and helped with the reconstruction of the church of S. Giovannino in Florence, funding a chapel where they were buried.

Abstract The studied limestone is a well known Portuguese natural stone that occurs in Valverde – Alcanede region, located in the Maciço Calcário Estremenho (centre of Portugal). This stone is used in several exterior and interior applications such as paving, cladding, masonry and decorations. Slabs made of the studied limestone were installed in ventilated facade with a “kerf” anchoring system in a building located in Valencia (Spain). After approximately five years, signs of degradation were detected on the facades through changes in color, cracks and fissures that caused instability and collapse on several slabs. Limestone slabs comprise irregular patterns due to rock cutting across stylolites. These features represent ideal paths for fluid circulation through the slab and can be identify as vulnerability zones for exterior applications. Experimental procedure included several laboratory analyses in order to study clays and the iron oxide contents. Microscopic petrography, XRD and SEM observations were important to identify the interaction of the clay material in stylolites and fossil contours. Results show the importance of establishing standard methods for selecting stone on cladding applications. From the results, it is possible to understand that clay minerals have a strong influence on the mechanical performance of this stone. Among other important remarks, results show the importance of the development of standard procedures that acknowledge the structure and mineral composition before setting these natural products as construction materials. Proper stone selection was found important to avoid facade degradation, and hence contribute to prevent accidents and promote user safety as well as economic impacts.

It is well known that strain fields can have a strong influence on the details of HREM images. This, for example, can cause problems in the analysis of edge-on interfaces between lattice mismatched materials. An interesting alternative to conventional HREM imaging has recently been advanced by Pennycook and co-workers where the intensity variation in the annular dark field (ADF) detector is monitored as a STEM probe is scanned across the specimen. It is believed that the observed atomic-resolution contrast is correlated with the intensity of the STEM probe at the atomic sites and the way in which this varies as the probe moves from cell to cell. As well as providing a directly interpretable high-resolution image, there are reasons for believing that ADF-STEM images may be less suseptible to strain than conventional HREM. This is because HREM images arise from the interference of several diffracted beams, each of which is governed by all the excited Bloch waves in the crystal.

Pt/Co multilayers displaying perpendicular (out-of-plane) magnetic anisotropy and 100% perpendicular remanent magnetization are strong candidates as magnetic media for the next generation of magneto-optic recording devices. The magnetic coercivity, Hc, and uniaxial anisotropy energy, Ku, are two important materials parameters, among others, in the quest to achieving higher recording densities with acceptable signal to noise ratios (SNR). The relationship between Ku and Hc in these films is not a simple one since features such as grain boundaries, for example, can have a strong influence on Hc but affect Ku only in a secondary manner. In this regard grain boundary separation provides a way to minimize the grain-to-grain magnetic coupling which is known to result in larger coercivities and improved SNR as has been discussed extensively in the literature for conventional longitudinal recording media.We present here results from the deposition of two Pt/Co/Tb multilayers (A and B) which show significant differences in their coercive fields.

Background: Suicide prevention is a major challenge for penal institutions in many countries. The traditional approach relies on the expertise of health professionals and is supplemented by the intervention of other professionals and the inmates themselves. New methods of suicide prevention based on peer support have been developed in recent years. Peer prevention programs rely on the ability of inmates to identify suicide risk. Aims: This study examines perceived suicide risk among inmates and explores possible explanations. Method: 54 inmates and 17 professionals working in prisons responded to a questionnaire. Results: The peer prevention program was found to change inmates’ expectations of support in the event of a suicide crisis. The study also found that the inmates involved in the program tended to underestimate the risk of suicide. The perception of the prevention program and the level of self-consciousness were found to account for the underestimation of suicide risk. Conclusions: Support for inmates involved in suicide prevention programs must take into account their isolation in prison. The training provided to inmates must also consider the biases affecting the assessment of risk.
