Traces of the Invisible: How an Alternative Reading of The Sleeping Beauty Fashioned a Bookwork Heightening Awareness of the Role of the Anesthetist.

J Med Humanit 2020 Mar;41(1):41-51

The Royal Society of Sculptors, London, UK.

This article discusses a Leverhulme residency undertaken by the author Julie Brixey-Williams in 2003-4 at the Association of Anaesthetists of Great Britain and Ireland. Notions of medical visibility were explored through practice-led investigations under the umbrella title, Traces of the Invisible, that concentrated on making concrete, visible responses to the hidden or intangible elements of the anesthetist's working life in areas such as sleep, breath, pain and genetic markers. Rosebud is a unique nine-foot concertina bookwork created after reading the entire story of The Sleeping Beauty into an anesthetic machine. Read More

Terahertz Time-Domain Reconstruction of Coating Microstratigraphy on Gilded Surfaces.

Materials (Basel) 2019 Nov 21;12(23). Epub 2019 Nov 21.

Istituto di Fisica Applicata "Nello Carrara", Consiglio Nazionale delle Ricerche, v. M. del Piano 10, 50019 Sesto Fiorentino (FI), Italy.

Here, a systematic study in order to assess the potential of THz time domain reflectometry for measuring the thicknesses of overpaint layers applied on original gilded surfaces was carried out. The work is part of a thorough characterization campaign, which is going on at the Rijksmuseum for addressing the conservation problems of a set of 19th century gilded picture frames on which heavy coatings were applied in previous undocumented restoration interventions. To perform such non-invasive thickness measurements, an analytical protocol based on Gaussian fits of the THz pulse-echo temporal profiles was optimized through the preparation of suitable technical samples and the comparison with direct thickness measurements.

[Pollen morphology of species of genus Senna (Fabales: Fabaceae) in Southeast Ibera, Corrientes, Argentina].

Rev Biol Trop 2014 Jun;62(2):769-82

The system of Ibera lake and marshes in the Province of Corrientes, covers an area of approximately 12 000km2, and is considered one of the most important wetlands in Latin America. Given the wide diversity of tropical communities in this area, it is important to generate new information about the different species of this ecosystem, through pollen morphology, as lake sediments favor the pollen grains conservation. With the aim to promote future research on systematics, vegetation history and melissopalynology of this region, this study attempted to describe the pollen morphology of the well represented genus Senna.

Classification of grass pollen through the quantitative analysis of surface ornamentation and texture.

Proc Biol Sci 2013 Nov 18;280(1770):20131905. Epub 2013 Sep 18.

Department of Plant Biology, University of Illinois, , Urbana, IL 61801, USA, Department of Mathematics, Florida State University, , Tallahassee, FL 32306, USA, Department of Computer Science, University of California, , Irvine, CA 92697, USA.

Taxonomic identification of pollen and spores uses inherently qualitative descriptions of morphology. Consequently, identifications are restricted to categories that can be reliably classified by multiple analysts, resulting in the coarse taxonomic resolution of the pollen and spore record. Grass pollen represents an archetypal example; it is not routinely identified below family level. Read More

Capturing the surface texture and shape of pollen: a comparison of microscopy techniques.

PLoS One 2012 12;7(6):e39129. Epub 2012 Jun 12.

Institute for Genomic Biology, University of Illinois, Urbana, Illinois, United States of America.

Research on the comparative morphology of pollen grains depends crucially on the application of appropriate microscopy techniques. Information on the performance of microscopy techniques can be used to inform that choice. We compared the ability of several microscopy techniques to provide information on the shape and surface texture of three pollen types with differing morphologies. Read More

Novel approach to the microscopic inspection during laser cleaning treatments of artworks.

Anal Bioanal Chem 2012 Feb 9;402(4):1585-91. Epub 2011 Aug 9.

Istituto di Fisica Applicata Nello Carrara, 50019 Florence, Italy.

The present work focuses on the potential of 3D digital microscopy for assessing micro-morphological features during laser cleaning treatments of artworks. This application requires preliminary optimization studies aimed at defining operative irradiation parameters and practicable degree of cleaning, as well as in situ diagnostic assessments during the restoration work. To this goal, we developed and tested a dedicated 3D digital microscope by implementing the "shape-from-focus" technique. Read More

Pollen and anther ontogeny in Cabomba caroliniana (Cabombaceae, Nymphaeales).

Am J Bot 2008 Apr;95(4):399-413

Department of Ecology and Evolutionary Biology, University of Tennessee, Knoxville, Tennessee 37996 USA.

Cabomba is a small water lily genus that is native to the New World. Studies of pollen development and associated changes in the anther yield valuable characters for considering the evolution of reproductive biology in seed plants. Here we characterized the complete ontogenetic sequence for pollen in Cabomba caroliniana. Read More

[Skull and mandible. On Joseph Beuys' "ancient sled." Medical art history observation].

Authors:
H Schulz

Mund Kiefer Gesichtschir 1999 May;3 Suppl 1:S7-11

Institut für Pathologie, Städtische Kliniken Osnabrück.

Few people are aware that Joseph Beuys (1921-1986), one of the most important artists at the end of the twentieth century, studied various aspects of the human skull. Beuys used teeth (especially molars), antlers, and horns as organically differentiated formations of solid substances of the viscerocranium, associating them in a very visual way with the "streaming circulation" principle. In addition, in his early drawings, in particular, Beuys replaced the lower jaw with a sledge. Read More
