T1 - A Novel Dry Treatment for Municipal Solid Waste Incineration Bottom Ash for the Reduction of Salts and Potential Toxic Elements N2 - The main obstacle to bottom ash (BA) being used as a recycling aggregate is the content of salts and potential toxic elements (PTEs), concentrated in a layer that coats BA particles. This work presents a dry treatment for the removal of salts and PTEs from BA particles. Two pilotscale abrasion units (with/without the removal of the fine particles) were fed with different BA samples. The performance of the abrasion tests was assessed through the analyses of particle size and moisture, and that of the column leaching tests at solid-to-liquid ratios between 0.3 and 4. The results were: the particle-size distribution of the treated materials was homogeneous (25 wt % had dimensions <6.3 mm) and their moisture halved, as well as the electrical conductivity of the leachates. A significant decrease was observed in the leachates of the treated BA for sulphates (44%), chlorides (26%), and PTEs (53% Cr, 60% Cu and 8% Mo). The statistical analysis revealed good correlations between chloride and sulphate concentrations in the leachates with Ba, Cu, Mo, and Sr, illustrating the consistent behavior of the major and minor components of the layer surrounding BA particles. In conclusion, the tested process could be considered as promising for the improvement of BA valorization.

T1 - Analyzing Immunity in Non-model insects Using De Novo Transcriptomics N2 - With the advent of widely accessible and cost-effective next-generation sequencing technologies, it has become increasingly feasible to study insect immunity on a deep genomic or transcriptomic level. Here we introduce a protocol that is aimed at exploiting transcriptomic data to study immunity in non-model insect organisms. We provide instructions for an entire workflow, starting with successfiil extraction of insect RNA through to bioinformatic guidelines for the effective analysis of mRNA sequencing data. The RNA extraction procedure is based on TRIzol Reagent and a spin-column clean-up Step. The bioinformatic pipeline is intended to help users identify immune genes from de novo transcriptome data and includes guidelines for conducting differential gene expression analyses on transcriptomic data. The immune gene prediction method is based on inferring protein homologs with HMMERand Blastp and talces Advantage ofthe ImmunoDB database, which is a valuable resource for research on insect immune-related genes and gene families. The differential gene expression analysis procedure utilizes the DESeq2 package as imple� mented in R. We hope this protocol will serve as a usefi.il resource for researchers aiming to study immunity in non-model insect species.

T1 - Zerfallen, zerteilt, zerschnitten: die Humboldt Fragmente IX-XII und ihre Rekonstruktion N2 - In Berlin befinden sich Fragmente indigener Bilderhandschriften, die Alexander von Humboldt aus Mexiko mitbrachte. Fast alle stammen sie aus der ehemaligen Sammlung des Italieners Lorenzo Boturini, deren Reste heute über mehrere Länder verstreut sind. Der hohe Fragmentierungsgrad sowie ungeklärte Fragen zur Provenienz und Genese der Bruchstücke machen es schwierig, sie zu rekontextualisieren. Um dies dennoch zu erreichen, kommen einander ergänzende moderne natur- und kulturwissenschaftliche Methoden zum Einsatz. Als Beispiel einer Neuzuordnung werden die Humboldt-Fragmente IX-XII vorgestellt. Dass die vier Bruchstücke verwandt sind, wurde schon lange vermutet, nicht jedoch, dass sie zusammen mit einem nicht mehr vorhandenen Mittelteil ein einziges Dokument gebildet haben. Die Gründe für eine derartige Rekonstruktion werden als Ergebnis der Forschungsarbeiten diskutiert.

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.

T1 - Sizing materials used in Persian manuscripts and their behaviour against the mould fungus Aspergillus flavus N2 - Our earlier study based on historical and scientific analysis showed that Iranians used a considerable range of materials in the sizing process. Unlike many nations who used limited sizing materials to improve the mechanical strength and to smoothen the paper surface, Iranians have used various materials for sizing process from Taimurid (15th century) to Safawid (16th century) and Qajar (19th century) periods. Further to our earlier study on the Sizing Materials used in Persian manuscripts and miniature paintings, scientific analysis was carried out to investigate their behaviour against the mould fungus Aspergillus flavus. In the first stage fourteen different sizing materials that was identified from Persian historical recipes were reconstructed. In the second stage fungicidal property of each sizing samples against Aspergillus flavus fungus were identified that will be presented in this paper.

Entry 19 01 11* describes a waste material containing hazardous substances. It was shown that only the hazardous property HP14 (ecotoxic) is of relevance for the classification. If substances with the hazard statement code (HSC) H400, H410, H411, H412 and H413 are present in incineration bottom ash (IBA) above certain level the waste is classified as hazardous, otherwise it is non-hazardous (in this case 19 01 12). It was further shown that only Cu, Zn and Pb compounds have an impact on the classification using a summation rule: 100xΣ c(H410) + 10xΣ c(H411) + Σ c(H412). Limit value is 25 percent. It is obvious that H410 substances have the highest impact. Therefore, the knowledge of the elemental composition of IBA is not sufficient because the content of distinct chemical compounds (with the respective molecular weight) is needed. When the exact speciation is not known a worst-case approach has to be applied. A practical guideline for the estimation of HP14 was developed based on the definition of 4 substance groups: 1. Metals and alloys, 2. Water-soluble substances, 3. Oxides and carbonates and 4. Substances not soluble in weak acids. In substance group 1 only fine Zn powder has the HSC H410. Water-soluble substances are assumed to be H410 substances. Their concentrations are, however, regularly below the cut-off value of 0.1 %. The amount of substance group 3 is estimated by a selective extraction with maleic acid. According to the worst-case approach it is assumed that CuCO3xCu(OH)2 and ZnO represent the respective Cu and Zn species in IBA because these substances have the highest stochiometric factor. Even with this worst-case approach results from operators of IBA treatment plant showed that the limit value of 25 % is not exceeded. The requirements for utilization of IBA in Germany are defined in the Secondary Building Materials Decree (Ersatzbaustoffverordnung EBV) which was set into force in August 2023. Leaching methods (batch test or column test) with a liquid-to-solid ratio of 2 l/kg are applied. IBA fulfills the requirements for class HMVA-2. Actually, even a classification of IBA as hazardous (i.e 19 01 11*) would not affect utilization but handling and transport.
