T1 - Scientific Analysis of Leonardo’s Manuscript with Anatomic Drawings and Notes N2 - In this paper, we discuss the importance of scientifically investigating cultural artefacts in a non-invasive way. Taking as test case Leonardo da Vinci’s Manuscript with anatomic drawings and notes, which is stored in Weimar, we clarify fundamental steps in the chronology of this folio. By means of microscopy, infrared reflectography, UV photography, and X-ray fluorescence analysis, we were able to identify various types of sketching material and several varieties of iron gall ink. For his sketches, Leonardo used two different sketching tools, a lead pencil and a graphite pencil, as well as several types of ink for developing these sketches into drawings. With regard to ink, it is important to observe that there is no difference between the ink Leonardo used for drawing and the ink he used for writing text. Based on the materials analysed, we suggest a chronology for the creation of this unique folio.

Im Unterschied zu vielen anderen Graphischen Kabinetten, die ihre Rembrandt-Bestände bereits erfolgreich publiziert haben, existierte eine solche Gesamtschau in Weimar bisher nicht. Die nun vorliegende Publikation mit 51 Katalognummern umfasst alle, aktuell Rembrandt zugeschriebenen Blätter, alle rembrandtesken Zeichnungen, die ehemals als Werk Rembrandts angesehen wurden, aber auch alle Zeichnungen, die einmal mit Rembrandt und seiner Schule in Verbindung gebracht wurden. Der Titel "Der Bestand der Rembrandt-Zeichnungen in der Klassik Stiftung Weimar - Kritischer Katalog und materialtechnischer Befund" macht deutlich, dass hier neue Wege beschritten wurden. Auch diese Publikation basiert auf Quellen der klassischen Kunstgeschichte, wie etwa bestehende Werkverzeichnisse. Die Befunde werden jedoch mit materialwissenschaftlichen Erkenntnissen erheblich erweitert. Jedes der hier besprochenen Blätter wurde verschiedenen naturwissenschaftlichen Untersuchungen unterzogen, um die Materialität jeder Zeichnung in ihrer Gesamtheit zu bestimmen. Es wird der Versuch unternommen, die Materialität mit der klassischen Stilkritik zu verzahnen, um neue Hinweise auf die Genese, den Gebrauch oder die Funktion der Zeichnung zu erhalten. Nicht jedes naturwissenschaftliche Ergebnis findet sich im Katalogteil, aber alle Hinweise, die zum Verständnis der Materialität der Zeichnung unmittelbar notwendig sind, werden zitiert.

To reduce the cleaning loads and their effect on the odour perception of the occupants, a sensory test in indoor spaces and on building products is necessary in addition to VOC emission measurements of the contaminants. ISO 16000-28 provides the basis for odour assessment of products using a human olfactory panel. Through many years of experience and testing of these methods, it can now be assumed that reproducible odour ratings are available for many products used indoors. An odour measurement is mandatory for the Blue Angel for carpets and is being tested for environmentally friendly resilient floor coverings. Based on the results of an earlier project and new results of the upcoming study, the ISO should be revised and completed. The project investigates the odour and VOC emissions of building products based on natural raw materials. The data generated is used to address several issues, which are briefly explained below. Floor coverings based on linoleum and rubber are included in the Blue Angel eco-label with an odour assessment. The aim of the project is to clarify whether other assessment methods in addition to intensity can provide better information. Positive hedonics have an influence on the intensity assessment. Typically, building products show high intensity with low hedonic values. Results for wood-based products often show high intensity and positive hedonics. Based on these examples, an appropriate odour assessment of wood-based products for the Blue Angel, supported by research results, should be possible. The concept of the odour guide value which is based on odour threshold values was renewed in 2023. This approach will now be compared with the standardised odour measurement (16000-28). This assessment is based on GC/MS measurements and uses odour thresholds analytically when panel-based odour assessment is not possible. For this procedure well defined odour thresholds are necessary T2 - AIRMON 2025 The 11th International Symposium on Modern Principles of Air Monitoring and Biomonitoring.

Volatile organic compounds (VOCs) in indoor air can be determined by using passive samplers that are exposed to the air for a well-defined period of time. This sampling method is often used in environmental surveys, e.g. the German Environmental Survey (GerES). Conclusions about indoor air concentrations can be drawn from substance and adsorption material specific uptake rates. For the assessment of indoor air quality, highly volatile organic compounds may also be substantial, but for many of these substances realistic uptake rates and suitable analytical methods are lacking. A small chamber is used to generate gas atmospheres with constant concentrations of the analytes at 23 °C and 50 % relative humidity. For a large number of compounds, a very small flow of pure liquid VVOCs is introduced into the chamber via a syringe pump and mixed with a constant flow of clean and humidified air. A gas mixture from cylinders is also used for this purpose. Carbograph 5TD has already been proven as a suitable sorption material for active sampling for most of VVOCs. With this procedure up to 55 different VVOCs should be tested in this study. Stable concentrations of gas phase atmospheres of the first group of VVOCs (acetone, 2-butanone, methyl acrylate) were produced for exposure of passive samplers. Comparison of different adsorbent materials showed that Carbograph 5TD was the most suitable for passive sampling of these substances, with higher uptake than Carbopack X and Tenax® TA. Very strong adsorbents are not suitable for this experimental design as it adsorbs larger amounts of water. The effective uptake rates were calculated for the first three VVOCs on Carbograph 5TD tubes and an exposure time of 7 days. The same experiment will be performed for all VVOCs and ideally one material should be the best option for all of them.

A1 - Calvillo, Nelson A1 - Rabin, Ira T1 - Did the Original Scribes Write the Distigmai in Codex Vaticanus B of the Bible (Vat. gr. 1209)? N2 - The fourth-century Greek Bible manuscript Codex Vaticanus B (Vat. gr. 1209) contains pairs of horizontally aligned marginal dots known as distigmai, which correspond to textual variants in other manuscripts. The production of the distigmai has been variously dated to the 4th or 16th centuries. A fourth-century date would prove the early existence of hundreds of textual variants, many of which are otherwise only witnessed by later manuscripts. Near infrared microscope reflectography combined with micro-X-ray fluorescence spectroscopy proved that the distigmai, both those categorized as “apricot” (which are visually similar to the ink of the original main text) and “chocolate” (which are visually similar to the reinking of the main text) were written with ink(s) made from chemically purified vitriol, a process that only became standard in the 16th century. As a result, there is no reasonable chance that the distigmai were written in the fourth century. Horizontal lines that have been hypothesized to function as text-critical obeloi were written in the same ink as the original main text, which differs completely from that of the distigmai. In other words, the distigmai and horizontal lines tested were not produced during the same writing session and are separated by more than 1,000 years, making it impossible for them to have functioned as conjoining text-critical symbols in the 4th century.

This was due partly to the number of newly discovered fragments and to the invention of new instruments and scientific procedures to identify animal skins and produce qualitative means to demonstrate specific preparation reagents and techniques. The invention of various means of analyzing the DNA of organic materials brought about a revolution in archaeology and in conservation. Difficulties in overcoming contamination of archaeological samples resulted in a number of controversies but also produced advances and improvement in the techniques of ancient DNA analysis and interpretation of results.
