TY - CHAP A1 - Ghigo, Tea A1 - Torallas, S. T1 - Between Literary and Documentary Practices: The Montserrat Codex Miscellaneus (Inv. Nos. 126‐178, 292, 338) and the Material Investigation of Its Inks N2 - The Montserrat Codex Miscellaneus (TM 59453/LDAB 552) has been the subject of numerous studies since the publication of ist first text by its owner, father Ramon Roca-Puig. Scholars have dealt with the content of its texts, as well as interrogated its origin and materiality. It is a fourth-century papyrus single quire codex, which contains texts in both Latin and Greek. It has been argued that it belonged to the Bodmer library, connected to a Pachomian library in the Thebaid. In this paper we want to contribute to the material study of the codex by presenting the first results of an archaeometric analysis performed upon the inks. The Analysis was carried out within the framework of the ‘PAThs’ project based at Sapienza University of Rome, and executed with the close cooperation of DVCTVS, a team of scholars who curate the Roca-Puig collection. The results obtained have not only cast light on the history of production of the codex, but also, and perhaps most importantly, point out that a meaningful interpretation of the analytical data is only possible through an interdisciplinary collaboration between the humanities and the natural sciences.

T1 - EI‐GEO environmental impact of geosynthetics in aquatic systems N2 - EI‐GEO is a multinational research project (Germany, Latvia, Russia) funded under the ERA.Net RUS Plus Call 2017. Aim of the project is the investigation whether geosynthetics in hydraulic engineering applications could be a source of microplastics (MPs) and other contaminants to the aquatic environment causing negative effects to aquatic organisms. Whereas the behavior of geosynthetics in landfill engineering is well studied and documented since decades, little is known on application in applications such as coastal protection or ballast layers for wind energy plants. However, due to the rapid expansion of offshore wind energy, rising water levels and more extreme weather conditions as a result of climate change more and more hydraulic engineering projects will be realized in the future. Applied methods are artificial ageing of geosynthetics in environmental simulation chambers, storage of samples under environmental condition for comparison with laboratory simulation, sample characterization by microscopic methods and ecotoxicological testing of water in contact with geosynthetics. In parallel a case study at the Baltic Sea shore at Kaliningrad Oblast (Russia) will be performed. The aim of study is to estimate the level of pollution of the beaches by geosynthetic debris and identify the possible sources.

Standardized leaching tests are used to measure the extent of mobilization. It is known that fresh bottom ash displays elevated concentrations of various heavy metals such as lead or zinc due to the formation of hydroxo complexes as a result of high pH values of 12 and above. Storage of BA is accompanied by ageing processes, mainly the reaction of CaO and Ca(OH)2 with CO2 leading to lower pH values in contact with water around 11. Usually heavy metals concentrations are minimum at these conditions. Knowledge of the long-term leaching behavior of potentially harmful substances is crucial for the assessment of the environmental compatibility of reusing municipal solid-waste incineration bottom ash (MSWI BA) in construction, i.e., as a road base layer. BA fractions obtained from wet-processing aiming at the improvement of environmental quality were used to investigate the mobility of relevant substances. Eluates from laboratory-scaled leaching procedures (column percolation and lysimeters) were analyzed to learn about the long-term release of substances. Unsaturated conditions and artificial rainwater were used in the lysimeter tests to simulate field conditions. In addition, batch test eluates were generated at usual liquid-to-solid ratios (L/S) for compliance testing purposes. A variety of cations and anions was measured in the eluates. The wet treatment reduces the leaching of chloride and particularly sulfate by more than 60%. The release of typical contaminants for the treated MSWI BA such as the heavy metals Cu and Cr was well below 1% in the conducted leaching tests. An increase in the Sb concentration was observed in the lysimeter experiments starting at L/S 0.75 L/kg and in the column experiment at L/S 4 L/kg is assumed to be related to decreasing concentrations of Ca and thus to the dissolution of sparingly soluble calcium antimonate. The same leaching mechanism applies with V, but the concentration levels observed are less critical regarding relevant limit values. However, on the long term the behavior of Sb could be problematic for the application of MSWI BA as secondary building material.

These results can be set in a historical context and help to confirm art historical interpretations. Proofs of certain pigments can be used for dating purposes and may reveal if the artist used not only local but also imported materials. A pilot study of two Chinese reverse glass paintings from the late 19th (Yingying and Hongniang) and early 20th centuries (The Archer) was performed using a multi-analytical approach including X-ray fluorescence (XRF), diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and Raman spectroscopy. This approach allowed the identification of the pigments and the classification of the binding media. The results reveal a combined use of traditional Chinese and imported European materials. Several pigments like cinnabar, lead white, orpiment, carbon black and copper-arsenic green (probably emerald green) were found in both paintings; red lead, artificial ultramarine blue, Prussian blue and ochre appear in at least one of the paintings. The proof of limewash (calcite and small amounts of portlandite) as a backing layer in “Yingying and Hongniang” indicates that clamshell white was also used for reverse glass paintings. Drying oil was classified as a binding media in most areas of both paintings. However, the orange background of The Archer yielded prominent bands of both proteinaceous and fatty binder.

T1 - Uninvited and welcomed guests in museums – biological management of clothes moths and woodworms N2 - In museums and historic houses clothes, moths (Tineola bisselliella, Tinea pellionella) and the furniture beetle (Anobium punctatum) are the most economically important pests on textiles or wooden artifacts, respectively. Their management is essential to protect cultural ethnological heritage and natural history collections for future generations. Pest management strategies have changed over time. Today, intensive knowledge on pest biology and overall material science are key cornerstones in IPM concepts - also for the Museum environment. The important first steps for sustainable pest management are risk assessment, early pest detection and identification of pathways of infestation. These steps are followed by physical and biological means of control, which have lately gained more importance than applying biocides. Several potentially effective biological enemies of clothes moths and woodworm have been known for a long time, but their promotion for pest control in Museums and historic houses is just beginning. This short review summarizes current concepts of pest life cycle interruption by applying good quarantine and very specific biological measures. The lessons learned from recent faunistic surveys, life-history studies as well as behavioral observations of parasitoids and predators of clothes moths and woodworm may supplement the pest management tool box. The need for further research in this field is addressed.

T1 - High-Throughput Cultivation for the Selective Isolation of Acidobacteria From Termite Nests N2 - Microbial communities in the immediate environment of socialized invertebrates can help to suppress pathogens, in part by synthesizing bioactive natural products. Here we characterized the core microbiomes of three termite species (genus Coptotermes) and their nest material to gain more insight into the diversity of termite-associated bacteria. Sampling a healthy termite colony over time implicated a consolidated and highly stable microbiome, pointing toward the fact that beneficial bacterial phyla play a major role in termite fitness. In contrast, there was a significant shift in the composition of the core microbiome in one nest during a fungal infection, affecting the abundance of wellcharacterized Streptomyces species (phylum Actinobacteria) as well as less-studied bacterial phyla such as Acidobacteria. High-throughput cultivation in microplates was implemented to isolate and identify these less-studied bacterial phylogenetic group. Amplicon sequencing confirmed that our method maintained the bacterial diversity of the environmental samples, enabling the isolation of novel Acidobacteriaceae and expanding the list of cultivated species to include two strains that may define new species within the genera Terracidiphilus and Acidobacterium.

T1 - The compatible solute ectoine: protection mechanisms, strain development, and industrial production N2 - Bacteria, Archaea, and Eukarya can adapt to saline environments by accumulating compatible solutes in order to maintain an osmotic equilibrium. Compatible solutes are of diverse chemical structure (sugars, polyols, amino acid derivatives) and are beneficial for bacterial cells not only as osmoregulatory solutes but also as protectants of proteins by mitigating detrimental effects of freezing, drying, and high temperatures. The aspartate derivative ectoine is a widespread compatible solute in Bacteria and possesses additional protective properties compared with other compatible solutes and stabilizes even whole cells against stresses such as ultraviolet radiation or cytotoxins. Here, it is our intention to go beyond a simple description of effects, but to depict the molecular interaction of ectoine with biomolecules, such as proteins, membranes, and DNA and explain the underlying principles. The stabilizing properties of ectoine attracted industry, which saw the potential to market ectoine as a novel active component in health care products and cosmetics. In joint efforts of industry and research, a large-scale fermentation procedure has been developed with the halophilic bacterium Halomonas elongata used as a producer strain. The development and application of ectoine-excreting mutants from H. elongata (“leaky” mutants) allow for the annual production of ectoine on a scale of tons. The details of the strain development and fermentation processes will be introduced.

T1 - Termite resistance of pine wood treated with nano metal fluorides N2 - Fluorides are well-known as wood preservatives. One of the limitations of fluoride-based wood preservatives is their high leachability. Alternative to current fluoride salts such as NaF used in wood protection are low water-soluble fluorides. However, impregnation of low water-soluble fluorides into wood poses a challenge. To address this challenge, low water-soluble fluorides like calcium fluoride (CaF2) and magnesium fluoride (MgF2) were synthesized as nanoparticles via the fluorolytic sol−gel synthesis and then impregnated into wood specimens. In this study, the toxicity of nano metal fluorides was assessed by termite mortality, mass loss and visual analysis of treated specimens after eight weeks of exposure to termites, Coptotermes formosanus. Nano metal fluorides with sol concentrations of 0.5 M and higher were found to be effective against termites resulting in 100% termite mortality and significantly inhibited termite feeding. Among the formulations tested, the least damage was found for specimens treated with combinations of CaF2 and MgF2 with an average mass loss less than 1% and visual rating of “1”. These results demonstrate the efficacy of low water-soluble nano metal fluorides to protect wood from termite attack.

In diesem Projekt wurde das Messverfahren und der Prüfwert für die Partikelemission aus Bürogeräten (siehe Vergabegrundlage DE-UZ 205, Anhang S-M) validiert und weiterentwickelt. Dies geschah erstens durch Auswertung der Qualität der im Zuge der Antragsbearbeitung für das Umweltzeichen beim RAL vorgelegten Prüfberichte der zugelassenen Prüfinstitute und - basierend darauf - durch Erarbeitung von technisch-methodischen Veränderungsvorschlägen für die Prüfung der chemischen Emissionen, inklusive der Partikelemissionen. Zweitens wurde zur Beurteilung der Veränderung der Emissionen aktueller gegenüber älteren Geräte-generationen ein nicht repräsentativer Pool von table-top-Laserdruckern aufgebaut und die chemischen Emissionen wurden gemäß DE-UZ-205, Anhang S-M gemessen. Ergänzend wurde eine quantitative chemische Analyse der anorganischen Feststoffe - insbesondere der Metalle - in den emittierten Aerosolen vorgenommen die Feststoffgehalte um 2 Massen-% ergaben. Diese Ergebnisse wurden gemeinsam mit neueren wissenschaftlichen Untersuchungen zur gesundheitlichen Bewertung der Emissionen aus Laserdruckern ausgewertet, es besteht kein Handlungsbedarf hinsichtlich einer Veränderung von Prüfkriterien und Prüfwerten. Drittens wurde untersucht und bestätigt, dass mit dem Ziel eines zukünftigen Umweltzeichens das Emissionsverhalten Kunststoff verarbeitender 3D-FDM-Drucker und/oder die darin verarbeiteten Verbrauchsmaterialien (Filamente) mit dem für Laserdrucker entwickelten Mess- und Prüfschema charakterisiert und quantifiziert werden können.

PerFluSan möchte einen entscheidenden Beitrag zur Lösung dieses Problems leisten, indem hier neue PFAS-Sanierungs­verfahren für Böden und Wässer, sowie innovative analytische Methoden zum PFAS-Nachweis entwickelt werden. Die lang­fristige Vision ist es, PerFluSan zu einer nationalen Anlauf­stelle der PFAS-Thematik auszubauen, die mit Hilfe der Synergien zwischen den PerFluSan-Akteuren alle Aspekte der Problematik ganz­heitlich, nachhaltig und effektiv adressiert.

The sustainable protection of people and the environment from this group of substances is an important task for the future. However, available PFAS removal and remediation processes are expensive and often inadequate. PerFluSan would like to make a relevant contribution to solve this problem by developing new PFAS remediation methods for soils and water, as well as innovative analytical methods for PFAS detection. The long-term vision is to develop PerFluSan into a national contact point for the PFAS topic, which uses synergies between the PerFluSan actors to address all aspects of the problem holistically, sustainably and effectively.

An interfacial pH of 9.61 at −0.9 V vs. SCE using state of the art iridium oxide microelectrode was found to be the critical pH for the precipitation of magnesium hydroxide. Calcareous deposits with a double-layer structure comprising an inner-brucite layer and an outer-aragonite layer were found to form at potentials between −1.0 V and −1.2 V vs. SCE. Furthermore, the facilitation of hydrogen permeation into steel induced by the formation of calcareous deposits was verified using the Devanathan-Stachurski electrochemical test. The mechanism of calcareous deposits facilitates hydrogen permeation into steel is related to its inhibition on hydrogen recombination and escape processes.

New active ingredients, newer formulations, and novel wood-based materials including physically- and chemically-modified wood, together with increasing concerns over environmental impacts of wood preservatives, urgently demand a major revision of EN 275 “Wood preservatives – Determination of the Protective Effectiveness against Marine Borers”, dated from 1992. This IRG document reports on the technical work in CEN TC 38 regarding the revision of this standard. A Task Group within WG 24 of CEN TC 38 was formed consisting of experts from different field of competence (e.g. wood preservatives industry, wood scientists, marine biologists, archaeologists and cultural heritage conservators). Starting by e-mail correspondence in 2014, and continuing with four physical meetings (Berlin 2x, Florence, Venice) with experts from Germany, Italy, Sweden, and UK were held so far. Significant items for revision in EN 275 were identified as: number of replicates, duration of the test, dimension of specimens, number of test sites, number of reference species, reference material including reference preservative, re-immersion of specimens after non-destructive periodical evaluation for longer periods of time vs higher number of replicates for successive destructive examinations without re-immersion, utilization of X- ray apparatus and specific software to ease evaluation, etc. Furthermore, the task group is working on a standardized lab test for time-saving evaluation of different wood qualities for their potential to resist attack by limnorids. The suitability of this lab test will be determined by round robin tests as soon as safe face-to-face collaboration permits. The outcome will be published as a CEN TR (Technical Report) document, with a view to eventual adoption within the revised standard.

Ziel des Vorhabens war es, durch die Auswertung vorhandener und durchzuführender Untersuchungen eine Einstufung von Bodenmaterialien (jährlich fallen weit über 100 Mio. Tonnen davon an) für bestimmte Verwertungswege vornehmen zu können. Es sollte herausgefunden werden, ob Veränderungen hinsichtlich des Verwertungspotentials nachgewiesen werden können. Basis für die Durchführung und Bewertung waren die neuen Regelungen (hier insbesondere die Untersuchung mit einem Wasser/Feststoffverhältnis von 2:1, neue nationale und europäische Elutions- und Untersuchungsverfahren) der novellierten BBodSchV. Der Fokus lag dabei auf den polyzyklischen aromatischen Kohlenwasserstoffen (PAK) sowie ausgewählte anorganische Stoffe (Schwermetalle und Anionen) unter der Berücksichtigung unterschiedlicher Bodenmaterialien zur Verwertung. Dabei handelte es sich um: - Böden aus urban geprägten Gebieten, - Oberböden aus dem Straßenrandbereich in Form von Bankettschälgut, - Baggergut aus Gewässern mit Verdacht auf eine Kontamination, - Bergematerial (Mischung von Abraum- und Bodenmaterial), - Auenböden mit vermuteten Verunreinigungen aus Industrie und Gewerbe. Anhand der vorgelegten Ergebnisse kann nun eine Versachlichung der Diskussion um Ressorcenschutz vs. Schadlosigkeit der Verwertung erfolgen. Sie zeigen für die untersuchten Stoffe, dass bei einer Einführung der §§ 6-8 Novelle BBodSchV mit einer Erhöhung der Verwertungsquote für Bodenmaterial gerechnet werden kann. Eine Erhöhung des Deponievolumens ist somit nicht zu befürchten. Neben den ermittelten Daten konnten Grundlagen für die Überarbeitung verschiedener DIN-Normen für Bodenuntersuchungen erarbeitet werden.

T1 - La invencíon del Sacromonte: How and Why Scholars Debated about the Lead Books of Granada for Two Hundred Years N2 - At the end of the sixteenth century, a number of relics and artefacts were discovered in Granada, Spain. They included what became known as the Lead Books of the Sacromonte, twenty-one written artefacts made of circular lead leaves engraved in archaic Arabic characters. The authorship was attributed to some Arab disciples of St James the Greater considered to be the first evangelisers of the Iberian Peninsula. The texts, the materiality and the circumstances of the discoveries fuelled a debate surrounding their authenticity that lasted more than two centuries, a debate so fierce and controversial that not even papal condemnation in 1682 was able to stop it. Soon after the discoveries were made public, scholars highlighted the many contradictions and errors of a historical, linguistic and theological nature present in the texts, identifying members of the local Morisco community as possible forgers. This article focuses on how the scholarly community of the sixteenth and seventeenth centuries handled these findings and looks at the methods employed by the scholars to evaluate the authenticity of the artefacts. It will also look at how the particular interests of the various authorities involved influenced the acceptance or dismissal of relevant academic results.

When exposed to the environment, PFASs slowly get mobilized by natural water resources, leading to contamination of large areas of soil and natural water sources. While PFASs contamination of drinking water has been investigated intensively, perfluoralkyl contamination of soils has been rarely examined as of yet. At the same time, an increasing amount of PFASs contamination sites are being discovered worldwide, calling for a sophisticated strategy towards analytical characterization. Since the number of known PFASs already exceeds 4700, the established sum parameters like extractable organic fluorine (EOF) and adsorbable organic fluorine (AOF) are key elements to fully survey the impact of exposure. Simultaneously, innovative soil remediation strategies are required to contain environmental destruction and to minimize further spreading of contaminants. Addressing these challenges requires suitable analytical devices that are capable of mobilizing PFASs in the solid as well as in the liquid phase. The use of combustion ion chromatography (CIC) enables analysis of both immobile and volatile PFASs and allows the detection of both total fluorine (TF) and EOF or AOF of a given soil or aqueous sample. Based on preliminary results, the clean-up of a PFAS contaminated solid matrix is monitored via EOF detection over time. Additionally, we demonstrate the pH dependency of hydrogen fluoride absorption on active carbon (AC) and found a simple organic additive to be an effective fluoride scavenger. The presented findings can be contributive with regard to future AOF/EOF sum parameter development and application.
