The coupled volume concert hall and its signature double sloped sound decay aim to partially reconcile the often-competing qualities of clarity and reverberance. A concert hall is conceived with a fixed geometric volume, form, and aperture size. A coupled volume is attached and its materiality is established as variable. Both statistical and geometric relative analyses suggest a highly sensitive relationship between the coupled volume reverberation time and the double-sloped condition.

The scanning transmission electron microscope (STEM) constructed by the authors employs a field emission gun and a 1.15 mm focal length magnetic lens to produce a probe on the specimen. The aperture size is chosen to allow one wavelength of spherical aberration at the edge of the objective aperture. Under these conditions the profile of the focused spot is expected to be similar to an Airy intensity distribution with the first zero at the same point but with a peak intensity 80 per cent of that which would be obtained If the lens had no aberration. This condition is attained when the half angle that the incident beam subtends at the specimen, 𝛂 = (4𝛌/Cs)¼

The article is focused on the analysis of the Zaryadye Concert Hall building in Moscow in terms of the significance of artificial lighting for the creation of the imagery and perception of this facility within the typology of entertainment music-oriented buildings. Through the example of modern places of entertainment, the author reveals a number of formal features (typological attributes), which, being common to buildings of this function, constitute the basis of their image and become obvious due to the realized lighting concept. The interpretation of these attributes in the interaction of architectural planning and lighting concepts in the Zaryadye Concert Hall is traced. In conclusion, the distinctive features of the building under consideration are determined. At the same time, they reflect a new understanding of concert halls as a building type, the changes related to the overall development of architecture, as well as the elements of the individual architectural language.

Background: Graves’ ophthalmopathy (GO), also known as Graves’ orbitopathy or thyroid eye disease, has a potential sight-threatening complications. The activity and severity are important determinants in GO and are implications for treatment. Intravenous Glucocorticoid (GC) was associated with significantly greater efficacy and was better tolerated than oral route in the treatment of patients with moderate to severe and active GO. Intravenous GC has a variation cumulative dose and protocols; meanwhile the optimal treatment is still undefined. The aim of this literature review was to analyze the outcome and safety of different cumulative doses and protocols of intravenous methylprednisolone of patients with moderate to severe and active GO. Methods: The literature search was conducted from Google Scholar and Pubmed for journal articles that were published and related to the use of IVGC in moderate to severe and active GO Results: From the keywords mentioned, titles were screened for eligibility and seventeen articles were found. After being checked for the duplication, the articles were screened based on the abstracts and/or full texts. As many as eight articles met the inclusion criteria, others were excluded. Conclusion: Intravenous GC therapy in moderate to severe and active GO provide effect in reducing CAS, decreasing lid aperture size, decreasing proptosis size, and disappearing diplopia. A protocol uses a low cumulative doses (<5 g) of methylprednisolone weekly for 6 weeks and then halved dose weekly for another 6 weeks are preferred due to higher response in clinical outcome and safety profile.

Ob Großraumbüros, Konzerthallen oder Auditorien – bau- und raumakustische Eigenschaften stellen nicht nur ein wichtiges Qualitätsmerkmal für Gebäude dar, sie bestimmen auch maßgeblich das Wohlgefühl der Nutzer. Wo bisherige Maßnahmen zum Schallschutz mit dem Wunsch nach einer idealen Temperierung von Gebäuden als unvereinbar galten, stellt die Weiss Doppelbodensysteme GmbH, Traditionsunternehmen aus dem schwäbischen Lindach, ein Produkt vor, welches es ermöglicht, beide Kriterien miteinander zu vereinen: Den Akustik-Doppelboden. &nbsp; Summary Whether open-plan offices, concert halls or auditoriums – building and room acoustics not only represent an important quality feature for buildings, they also significantly determine the well-being of the users. Where previous measures for sound insulation were considered incompatible with the desire for an ideal temperature control of buildings, Weiss Doppelbodensysteme GmbH, a traditional company from the Swabian town of Lindach, presents a product that makes it possible to combine both criteria: the acoustic double floor.

What did the Edwardians know about Spain, and what was that knowledge worth? The Edwardians and the Making of a Modern Spanish Obsession draws on a vast store of largely unstudied primary source material to investigate Spain’s place in the turn-of-the-century British popular imagination. Set against a background of unprecedented emotional, economic and industrial investment in Spain, the book traces the extraordinary transformation that took place in British knowledge about the country and its diverse regions, languages and cultures between the tercentenary of the Spanish Armada in 1888 and the outbreak of World War I twenty-six years later. This empirically-grounded cultural and material history reveals how, for almost three decades, Anglo-Spanish connections, their history and culture were more visible, more colourfully represented, and more enthusiastically discussed in Britain’s newspapers, concert halls, council meetings and schoolrooms, than ever before. It shows how the expansion of education, travel, and publishing created unprecedented opportunities for ordinary British people not only to visit the country, but to see the work of Spanish and Spanish-inspired artists and performers in British galleries, theatres and exhibitions. It explores the work of novelists, travel writers, journalists, scholars, artists and performers to argue that the Edwardian knowledge of Spain was more extensive, more complex and more diverse than we have imagined.
