Abstract. In this survey we present studies on mortar mixes added with oxblood, which was a commonly found local waste material, with a wide application and long history of use; a precise recipe of lime–pozzolan mortar with blood addition from a 19th-century Italian manual was chosen, and model samples were prepared accordingly, with the aim of better understanding the chemical, mineralogical and physical characteristics of such compositions, starting with a blank reference specimen. The specimens were analysed by means of scanning electron microscopy, infrared spectroscopy, thermal analysis and X-ray diffraction, and the results suggested that amorphous calcium carbonate could be formed in the specimens with oxblood addition. These preliminary results allow a better understanding of historical building practices, measuring effects induced by organic additives on mortar microstructure, as well as an evaluation of new performances obtained in mortar mixes. Moreover, this paper intends to propose a full multi-discipline approach to bridge the history of architecture and building materials to conservation science.

The argumentation of previous studies demonstrated the historical evolution of the materials in architecture and the position of the materials in the design process. The purpose is to recognize the role of materials in architectural design, and the materials are a core element of the design process. This paper is about the way materials can be used to create personality and character of the design. The research finds two overlapping roles for materials which are providing technical functionality and building personality. Thus building materials were one of the major factors for new innovation forms through the history of architecture. Keywords: Building Materials, Architectural Design, Technical Functionality, Aesthetic Attributes.

Sacred wooden architecture in Poland is a huge and still unrecognised research problem. It covers a number of issues of interdisciplinary character: from the properties of building materials and carpentry techniques, through constructionand architectural-spatial solutions, to cultural and natural conditions. Hence, the best way to study this problem is interdisciplinary research. The necessity of cooperation of representatives of various scientific disciplines became the basis for creating a team to study the wooden church of St Michael the Archangel in Domachowo, so far dated to 1568. As researchers representing various disciplines (including archaeology, history, art history, history of architecture, architecture, architectural conservation), we cite sources and research that allow us to formulate a thesis that the past of the Domachowo church dates back to the 14th century. Moreover, we present the research and methodological problems inscribed in the aforementioned church building, understood as a whole. Such a multifaceted approach allows us to redefine the current knowledge about the church in Domachowo.

This chapter shifts perspective from the history of architectural acoustics (as a branch of physics) to the history of architecture and practices of listening from around 1780 to 1830. In this period, operas, concerts, and spoken theater pieces, traditionally performed in the same venue, were increasingly regarded as separate genres, each related to a specific sonic reverberation time. As this chapter illustrates using acoustic data from major venues, this separation corresponded with ever-diverging concepts of acoustic design and the acoustic properties of new buildings. The shift occurred, first, because of the emergence of a bourgeois theater and music culture and, second, due to a fundamental epistemic shift in acoustic theory when sound reflection began to be thought of as a phenomenon related to energy, time, and building materials. The audience was conceived of as a group of genre-specific listening experts who paid attention to sound dying away over time.

Abstract An archaeological cellar has been excavated under the Basilica of Our Lady in Tongeren, as part of an extensive restoration and revitalization campaign that started in 1999, Figure 1. The cellar will enable to descend to the early Roman history of the site under and surrounding the basilica. The excavation and construction of the archaeological cellar were finished in 2007. After that the air-conditioning system and the accessibility of the cellar were installed In successive phases. At present, the integration of the archaeological cellar under the basilica with the archaeological field around the basilica is under construction. Building in the large cellar under the complete church without endangering the stability of the building was a complex construction work, as explained further in the paper. The project was realized in successive phases, to enable continuous use of the church for services as well as its accessibility as pilgrimage site. After the construction of the cellar, the focus shifted to the conservation of the archaeological remains in view of the future (touristic) exploitation of the cellar. In view of that, climate control in the cellar is crucial. The foundation footings and walls have been covered underground during centuries, and are now suddenly exposed to an inside environment with higher temperatures and lower humidity. The climate control measures during the construction works are presented, as well as the performance of the final permanent climate control installation. The specific consolidation and conservation works on the foundation masonries are profoundly discussed.

AbstractX-ray topography provides a non-destructive method of mapping point-by-point variations in orientation and reflecting power within crystals. The discovery, made by several workers independently, that in nearly perfect crystals it was possible to detect individual dislocations by X-ray diffraction contrast started an epoch of rapid exploitation of X-ray topography as a new, general method for assessing crystal perfection. Another discovery, that of X-ray Pendellösung, led to important theoretical developments in X-ray diffraction theory and to a new and precise method for measuring structure factors on an absolute scale. Other highlights picked out for mention are studies of Frank-Read dislocation sources, the discovery of long dislocation helices and lines of coaxial dislocation loops in aluminium, of internal magnetic domain structures in Fe-3 wt.% Si, and of stacking faults in silicon and natural diamonds.

Der Vortrag schlägt vor, nicht mehr den Menschen als letzte Referenz und vertrauten Maßstab der Architektur zu setzen, sondern Architekturen als Mediensysteme zu denken. Eine noch ungeschriebene Mediengeschichte der Architektur sollte daher auch und gerade in historischer Absicht nach formalen Entsprechungen zwischen Techniken des Entwerfens und solchen der Bauten suchen, in denen Praxis und Produkt zusammenfallen. </br></br>The paper proposes the consideration of architecture(s) as a media system, instead of imposing man as its ultimate reference and known measure. A media history of architecture – which remains to be written – should therefore search for formal correspondences between techniques of drafting and those of buildings, in which practice and product coincide.

Jojoba is a widely used medicinal plant that is cultivated worldwide. Its seeds and oil have a long history of use in folklore to treat various ailments, such as skin and scalp disorders, superficial wounds, sore throat, obesity, and cancer; for improvement of liver functions, enhancement of immunity, and promotion of hair growth. Extensive studies on Jojoba oil showed a wide range of pharmacological applications, including antioxidant, anti-acne and antipsoriasis, anti-inflammatory, antifungal, antipyretic, analgesic, antimicrobial, and anti-hyperglycemia activities. In addition, Jojoba oil is widely used in the pharmaceutical industry, especially in cosmetics for topical, transdermal, and parenteral preparations. Jojoba oil also holds value in the industry as an anti-rodent, insecticides, lubricant, surfactant, and a source for the production of bioenergy. Jojoba oil is considered among the top-ranked oils due to its wax, which constitutes about 98% (mainly wax esters, few free fatty acids, alcohols, and hydrocarbons). In addition, sterols and vitamins with few triglyceride esters, flavonoids, phenolic and cyanogenic compounds are also present. The present review represents an updated literature survey about the chemical composition of jojoba oil, its physical properties, pharmacological activities, pharmaceutical and industrial applications, and toxicity.

In this paper, we explore the historical background and the semantic underpinnings of a central, if marginally treated, metaphor of enlightenment and transmission in Chan discourse, “silent accord” 默契. It features centrally in Essentials of the Transmission of Mind 傳心法要, a text that gathers the teachings of Chan master Huangbo Xiyun (d. ca. 850), a major Tang dynasty figure. “Silent accord” is related to the concept of mind-to-mind transmission, which lies at the very core of Chan Buddhist self-understanding. However, Chan historiography has shown that this self-understanding was partially a product of the Song dynasty lineage records, historically retroactive syncretic constructs produced by monks and literati as efforts towards doctrinal and political recognition and orthodoxy. There are thus lacunae in the history of Chan thought opened up by the retrospective fictions of Song dynasty, and a lack of reliable, dateable documents from the preceding Tang dynasty era, possibly fraught with later additions. We situate the metaphor “silent accord” in the history of Chan thought by searching for its origins, mapping its functions in Chan literature, arguing for its influence and thereby its role in helping to bridge the 9th century gap.

AbstractRuins are a statement on the building materials used and the construction method employed. Casa Ippolito, now in ruins, is typical of 17th-century Maltese aristocratic country residences. It represents an illustration of secondary or anthropogenic geodiversity. This paper scrutinises these ruins as a primary source in reconstructing the building’s architecture. The methodology involved on-site geographical surveying, including visual inspection and non-invasive tests, a geological survey of the local lithostratigraphy, and examination of notarial deeds and secondary sources to support findings about the building’s history as read from its ruins. An unmanned aerial vehicle was used to digitally record the parlous state of the architectural structure and karsten tubes were used to quantify the surface porosity of the limestone. The results are expressed from four perspectives. The anatomy of Casa Ippolito, as revealed in its ruins, provides a cross-section of its building history and shows two distinct phases in its construction. The tissue of Casa Ippolito—the building elements and materials—speaks of the knowledge of raw materials and their properties among the builders who worked on both phases. The architectural history of Casa Ippolito reveals how it supported its inhabitants’ wellbeing in terms of shelter, water and food. Finally, the ruins in their present state bring to the fore the site’s potential for cultural tourism. This case study aims to show that such ruins are not just geocultural remains of historical built fabric. They are open wounds in the built structure; they underpin the anatomy of the building and support insights into its former dynamics. Ruins offer an essay in material culture and building physics. Architectural ruins of masonry structures are anthropogenic discourse rendered in stone which facilitate not only the reconstruction of spaces but also places for human users; they are a statement on the wellbeing of humanity throughout history.
