The restoration of monuments is of great interest, leading to more architecturally significant designs. Many promising approaches to building design foster a symbiosis of the old and the new. The ...paper examines the compromises between the structural and physical properties of a historic building intended for renovation, which has already undergone several renovations. Due to the limited optimization possibilities at specific levels of the renovation project, diagnostics were used during the examination of proposals. Part of the diagnostics involves measuring thermal conditions, as well as temperatures on the internal and external surfaces of the building envelopes. The study demonstrates how the properties of the outer shell affect thermal insulation and suggests methods for architects, planners and preservationists to preserve the structural forms of the facade. The goal was to show that, despite the absence of a new thermal insulation layer on the outside of the building, the standard requirements are not violated. On the inner surface of the envelope walls, the temperature does not drop below the critical value for mould growth. Additionally, there are examples of modifications to the original details and their shape after the restoration of this building.
This Editorial celebrates the 70th anniversary of the European Journal of Histochemistry since its foundation as Rivista di Istochimica Normale e Patologica, and introduces a Special Collection of ...selected articles on the application of the histochemical approach for investigating cell biological features and processes in animals and plants, and under diseased conditions. The year 2024 is a special one for histochemists, as 100 years ago J.W. Robert Feulgen and H. Rossenbeck introduced the histochemical procedure for the specific stoichiometric staining of DNA in histological samples: to commemorate this influential publication, three papers in the present issue are devoted to the application of the Feulgen reaction at light and electron microscopy, and in cytometry.

Since the 60s of last century Fractional Calculus exhibited a remarkable progress and presently it is recognized to be an important topic in the scientific arena. This survey analyzes and measures ...the evolution that occurred during the last five decades in the light of books, journals and conferences dedicated to the theory and applications of this mathematical tool, dealing with operations of integration and differentiation of arbitrary (fractional) order and their generalizations.
In the last decades fractional calculus (FC) became an area of intensive research and development. This paper goes back and recalls important pioneers that started to apply FC to scientific and ...engineering problems during the nineteenth and twentieth centuries. Those we present are, in alphabetical order: Niels Abel, Kenneth and Robert Cole, Andrew Gemant, Andrey N. Gerasimov, Oliver Heaviside, Paul Lévy, Rashid Sh. Nigmatullin, Yuri N. Rabotnov, George Scott Blair.
Over the past two decades, monarch butterfly populations have been declining. This decline has been partly attributed to the extensive loss of breeding habitat through the reduction of common ...milkweed (Asclepias syriaca, the larval host plant) through herbicides. While the decline of milkweed has been well documented in the US, less is known about its decline in Canada. To take a first step in quantifying its potential decline, we compared roadside milkweed abundance at sites around Ottawa, Ontario, Canada in 2018, to a county-wide estimate of milkweed abundance in 1943 and 1944. We also evaluated the effect of roadside characteristics on milkweed abundance at these sites. Current milkweed density in the Ottawa region is 33–86% lower than it was 75 years ago. We found milkweed at 67% of our 100 sites and found less milkweed at sites with a higher number of lanes in the road adjacent to the roadside. Interestingly, mowing indices were not significant predictors of milkweed abundance. Here we document the first quantitative evidence for milkweed decline over the past 75 years in Canada, which has likely contributed to the decline of breeding monarchs in Canada.
"This lucid and comprehensive collection of essays by an international group of scholars constitutes a photo-historical survey of select photographers who embraced National Socialism during the Third ...Reich. These photographers developed and implemented physiognomic and ethnographic photography, and, through a Selbstgleichschaltung (a self-co-ordination with the regime), continued to practice as photographers throughout the twelve years of the Third Reich. The volume explores, through photographic reproductions and accompanying analysis, diverse aspects of photography during the Third Reich, ranging from the influence of Modernism, the qualitative effect of propaganda photography, and the utilisation of technology such as colour film, to the photograph as ideological metaphor. With an emphasis on the idealised representation of the German body and the role of physiognomy within this representation, the book examines how select photographers created and developed a visual myth of the ‘master race’ and its antitheses under the auspices of the Nationalist Socialist state. Photography in the Third Reich approaches its historical source photographs as material culture, examining their production, construction and proliferation. This detailed and informative text will be a valuable resource not only to historians studying the Third Reich, but to scholars and students of film, history of art, politics, media studies, cultural studies and holocaust studies."
Sometimes it is said that white is not a color but “the sum of all colors.” Surely this confusion comes from considering colors only those that appear in the spectrum. If these were the only colors, ...then magenta would neither be a color, nor do brown and other colors that do not have a specific wavelength, but are produced by a mixture of different wavelengths. Contradictorily, white often appears as “the absence of color.” When pigments are used on canvas or paper, white is the surface that remains unpigmented, unpainted, “uncoloured.” The same confusion often occurs with regard to black. Black is said to be “the sum of all colors” when a blackish stain is obtained from the mixture of various pigments. And black is said to be the “absence of color” when all light radiation is removed. The aim of this article is to argue that black and white are also colors, and so are grays. Because color is a visual sensation (product of the interaction of luminous radiation with pigmented objects and observers). “Pigment” and “color” are not synonymous; “light radiation” and “color” are not synonymous either. And just as we have red, green, blue, or yellow visual sensations, we also have visual sensations of white, black, or gray. This argument is supported by a survey where lay people and experts are asked about this issue, and by a bibliographical research that looks into texts and color order systems developed by theorists since the ancient times to nowadays.
In this paper a masonry baroque church by Antonio Galli Bibiena in Villa Pasquali is analyzed using a multidisciplinary approach. The importance of this monument is due to the prestige of its ...architect and to the peculiar system of masonry perforated vaults, which is an unicum in architectural history. Nevertheless, until now this church has not been studied, but historical data and significant crack patterns have pointed out its high vulnerability. The first step related to the knowledge of the building consists of the historical record of archival documents, which allow for the identification of the vulnerable elements. An accurate geometric survey is carried out with Terrestrial Laser Scanning in order to detect the complex three-dimensional geometry of the structure and crack patterns. Finally, a three-dimensional finite element model of the entire structure is developed and a comparison between the numerical results and the damage survey is performed.
The seminar ‘Critical Approaches to the Modern and Contemporary Anglophone Romance Novel (From A Room with a View to Fifty Shades of Grey)’ was held at the Department of English of University of ...Basel in the Winter term of 2020. Articulated over fourteen weeks, the seminar introduces the students to the romance genre, following the development of the Anglophone romance novel from the beginning of the last century to the contemporary period. The syllabus is designed around a parallel exploration of primary texts alongside critical studies. The main goal is familiarizing students with the definitions, development, and cultural significance of popular romance fiction, educating them on the waves of scholarship on romance fiction, and exploring and problematizing the complex relationship between popular literature and literary scholarship. I share this report with the main intent of offering a platform for debate and the additional one of preserving and celebrating a truly unique and satisfying experience, professionally as well as personally. This report is also meant as a token of my gratitude to all the students who have attended both seminars and have, through their efforts and contributions, and despite the restrictions due to the pandemic, concurred to their success.
