Key elements of sacred landscapes of the Nile Delta were lakes, canals and artificial basins connected to temples, which were built on elevated terrain. In the case of temples of goddesses of an ambivalent, even dangerous, nature, i.e. lioness goddesses and all female deities who could appear as such, the purpose of sacred lakes and canals exceeded their function as a water resource for basic practical and religious needs. Their pleasing coolness was believed to calm the goddess' fiery nature, and during important religious festivals, the barques of the goddesses were rowed on those waters. As archaeological evidence was very rare in the past, the study of those sacred waters was mainly confined to textual sources. Recently applied geoarchaeological methods, however, have changed this situation dramatically: they allow in-depth investigations and reconstructions of these deltaic sacred landscapes. Exploring these newly available data, the paper presented here focuses on the sites of Buto, Sais and Bubastis, by investigating the characteristics of their sacred lakes, canals and marshes with respect to their hydrogeographical and geomorphological context and to their role in ancient Egyptian religion and mythology as well.
Within the ‘market of healing’ of Christian Egypt (here broadly considered as the fourth through twelfth centuries CE), ‘magical’ practitioners represent an elusive yet recurrent category. This article explores the evidence for magical healing from three perspectives – first, literary texts which situate ‘magicians’ in competition with medical and ecclesiastical healing; second, the papyrological evidence of Coptic-language magical texts, which provide evidence for concepts of disease, wellness, and their mediation; and finally confronting the question of how these healing traditions might be understood within the methodologically materialistic framework of academic history, using the concepts of placebo and healing as a performance.
Sacred water canals or lakes, which provided water for all kinds of purification rites and other activities, were very specific and important features of temples in ancient Egypt. In addition to the longer-known textual record, preliminary geoarchaeological surveys have recently provided evidence of a sacred canal at the Temple of Bastet at Bubastis. In order to further explore the location, shape, and course of this canal and to find evidence of the existence of a second waterway, also described by Herodotus, 34 drillings and five 2D geoelectrical measurements were carried out in 2019 and 2020 near the temple. The drillings and 2D ERT surveying revealed loamy to clayey deposits with a thickness of up to five meters, most likely deposited in a very low energy fluvial system (i.e., a canal), allowing the reconstruction of two separate sacred canals both north and south of the Temple of Bastet. In addition to the course of the canals, the width of about 30 m fits Herodotus’ description of the sacred waterways. The presence of numerous artefacts proved the anthropogenic use of the ancient canals, which were presumably connected to the Nile via a tributary or canal located west or northwest of Bubastis.
Geoarchaeological information presented here pertains to a subsidiary Nile channel that once flowed west of the main Sebennitic distributary and discharged its water and sediments at Egypt’s then north-central deltaic coast. Periodical paleoclimatic episodes during the later Middle and Upper Holocene included decreased rainfall and increased aridity that reduced the Nile’s flow levels and thus likely disrupted nautical transport and anthropogenic activity along this channel. Such changes in this deltaic sector, positioned adjacent to the Levantine Basin in the Eastern Mediterranean, can be attributed to climatic shifts triggered as far as the North Atlantic to the west, and African highland source areas of the Egyptian Nile to the south. Of special interest in a study core recovered along the channel are several sediment sequences without anthropogenic material that are interbedded between strata comprising numerous potsherds. The former are interpreted here as markers of increased regional aridity and reduced Nile flow which could have periodically disrupted the regional distribution of goods and nautical activities. Such times occurred ~5000 years B.P., ~4200–4000 years B.P., ~3200–2800 years B.P., ~2300–2200 years B.P., and more recently. Periods comparable to these are also identified by altered proportions of pollen, isotopic and compositional components in different radiocarbon-dated Holocene cores recovered elsewhere in the Nile delta, the Levantine region to the east and north of Egypt, and in the Faiyum depression south of the delta.
Wetlands are one of the most important ecosystems due to their critical services to both humans and the environment. Therefore, wetland mapping and monitoring are essential for their conservation. In this regard, remote sensing offers efficient solutions due to the availability of cost-efficient archived images over different spatial scales. However, a lack of sufficient consistent training samples at different times is a significant limitation of multi-temporal wetland monitoring. In this study, a new training sample migration method was developed to identify unchanged training samples to be used in wetland classification and change analyses over the International Shadegan Wetland (ISW) areas of southwestern Iran. To this end, we first produced the wetland map of a reference year (2020), for which we had training samples, by combining Sentinel-1 and Sentinel-2 images and the Random Forest (RF) classifier in Google Earth Engine (GEE). The Overall Accuracy (OA) and Kappa coefficient (KC) of this reference map were 97.93% and 0.97, respectively. Then, an automatic change detection method was developed to migrate unchanged training samples from the reference year to the target years of 2018, 2019, and 2021. Within the proposed method, three indices of the Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), and the mean Standard Deviation (SD) of the spectral bands, along with two similarity measures of the Euclidean Distance (ED) and Spectral Angle Distance (SAD), were computed for each pair of reference–target years. The optimum threshold for unchanged samples was also derived using a histogram thresholding approach, which led to selecting the samples that were most likely unchanged based on the highest OA and KC for classifying the test dataset. The proposed migration sample method resulted in high OAs of 95.89%, 96.83%, and 97.06% and KCs of 0.95, 0.96, and 0.96 for the target years of 2018, 2019, and 2021, respectively. Finally, the migrated samples were used to generate the wetland map for the target years. Overall, our proposed method showed high potential for wetland mapping and monitoring when no training samples existed for a target year.
Having control over the landscape played an important role in the geography and economy of Egypt from the predynastic period onwards. Especially from the beginning of the Old Kingdom, we have evidence that kings created new places (funerary domains) called (centers) and (Ezbah) for the equipment of the building projects of the royal tomb and the funerary cult of the king, as well as to ensure the eternal life of both kings and individuals. Kings used these localities in order to do so, and they oftentimes expanded the border of an existing nome and created new establishments. Consequently, these establishments were united or divided into new nomes. The paper discusses the geography of Lower Egypt and the associated royal domains in the early Fifth Dynasty based on the new discoveries from the causeway of Sahura at Abusir.

In die Jahrzehnte „um 1200 v. Chr.“ fällt einer der bedeutendsten Einschnitte in der Ur- und Frühgeschichte zwischen Mitteleuropa und der ostmediterranen Welt: Zerstörungen in der Levante werden mit den „Seevölkern“ verbunden, die unter Pharao Ramses III besiegt wurden. Auch auf Zypern und in Kilikien gab es Zerstörungen – ebenfalls durch die „Seevölker“? Das hethitische Großreich brach zusammen, das mykenische Palastsystem endete. Von der mittleren Donau breiteten sich die „Urnenfelderkulturen“ auf dem Balkan, nach West- und Mitteleuropa sowie auf die Apenninhalbinsel aus. Mehrere ihrer Elemente wurden früh auch im Ostmittelmeerraum nachgewiesen, weshalb auf eine „Urnenfelderwanderung“ in die Ägäis und darüber hinaus geschlossen wurde. Dieses Modell ist allerdings nur noch forschungsgeschichtlich relevant. Vielmehr ergibt eine detaillierte, nach Regionen differenzierte Analyse der archäologischen Quellen, daß sich die Ausprägungen der kulturellen Wandlungen zwischen Ägypten und dem südlichen Mitteleuropa zwischen dem 14. und dem 12./11. Jahrhundert v. Chr. deutlich unterschieden und bedeutende Veränderungen in einen größeren Zeitraum fielen als lediglich in die Jahre um 1200 v. Chr. selbst.
The Orphic Hymns consist of a prooemium and 87 hymns addressed to several deities in a late Orphic initiation of sorts. They were composed probably in Asia Minor during the second or third century CE. The bulk of these hymns are made up of divine epithets often linked together in chains of considerable length. The lexicon attempts to give a comprehensive account of the roughly 850 epithets, bringing together the most relevant information scattered in the scholarly literature and adding others from various sources (literary, epigraphic, lexicographic, scholia etc.) in order to provide an overview of their usage and the main details of their models.
To diagnose diseases correctly requires not only trained and skilled personnel, but also cost-intensive and complex equipment. Rapid tests can help with the initial evaluation, but result generation can also take up to several hours, depending on the test system. At this point, novel bioresponsive diagnostic systems are used, responding to the disease related shift of biological processes. They monitor changes in the biological environment and can react to them e.g. with the release of substances. This can be used in drug delivery formulations but can also help to diagnose diseases occurring in the oral cavity and inform patients of their state of health. The tongue is herein used as a 24/7 available detector.
In section I of this work, the foundation for the development of these diagnostic systems was laid. A suitable flavoring agent was found, which is stable, can be coupled to the N-terminus of peptides and has a strongly conceivable taste. For the optimization of the protease-sensitive linker (PSL), an analytical system was established (PICS assay), which determines protease-specific cleavable amino acid sequences. In order to replace the PMMA particles previously required, an acetyl protecting group was introduced N-terminally as it protects peptides and proteins in the human body from degradation by human aminopeptidase. The new synthesized flavor was examined with a NIH cell line for cytotoxicity and with an electronic tongue setup for its bitterness.
Section II deals with the structure of a system which detects severe inflammations in the oral cavity, e.g. PA. The established PICS assay was used to confirm the previously used PSL sequence in its application. Using solid phase peptide synthesis, 3 linkers were synthesized which respond to the elevated MMP concentrations present in inflammation. The resulting peptides were acetylated and coupled with HATU/DIPEA to the modified denatonium. Cutting experiments with MMPs over different concentration and time ranges confirmed the response of the diagnostic sensor to these enzymes. The obtained construct was examined for cell toxicity by WST assay. The masked bitterness of the sensors was confirmed by an electronic tongue setup.
To address non-human proteases (and thereby infections), section III focuses on the establishment of detection system of a cysteine protease SpeB expressed by Streptococcus pyogenes. The in-house expression of SpeB using E. coli cells was established for this purpose. An analysis of the SpeB cleavage sites was performed using a PICS assay setup. Four constructs with different PSL were synthesized analogous to section II. Cleavage experiments with the expressed and purified SpeB showed a response of two constructs to the protease. In addition, a system was established to quantify the concentration of SpeB in human saliva using western blot technique with subsequent quantification.
In section IV a compound was synthesized which can now be coupled to a flavor. The final coupled construct is able to detect present NA activity specifically from influenza A and B. The market for existing influenza diagnostics was explored to determine the need for such a system. A neuraminic acid was modified in positions 4 and 7 and protected in such a way that subsequent coupling via the hydroxy-group in position 2 was selectively possible.
In summary, this results in a diagnostic platform that can be used anywhere, by anyone and at any time. This represents a new dimension in the rapid diagnosis of inflammations and bacterial or viral infections.
Die Palliativmedizin gilt oft als ein vergleichsweise junges Themengebiet, welches in den zurückliegenden Jahrzehnten kontinuierlich an Bedeutung gewinnen konnte. Palliativmedizin ist jedoch keine reine Erfindung des 20. Jahrhunderts. So galt die Versorgung Schwerkranker oder Sterbender bereits viel früher als ärztliche Pflicht. Grundgedanke der Arbeit war es, palliativmedizinische Facetten im ärztlichen Handeln zu Beginn des 19. Jahrhunderts nachzuweisen. Hierzu erfolgte eine beispielhafte Betrachtung der chirurgische Hernien-Therapie des St. Johanns Spitals in Salzburg. Als Grundlage dienten handschriftlich verfasste Krankengeschichten des St. Johanns Spitals aus der ersten Hälfte des 19. Jahrhunderts. Neben der Detektion und einer vergleichenden Darstellung palliativmedizinischer Handlungsweisen gelang mit Hilfe der in ihrer Ausführlichkeit bemerkenswerten Primärquelle eine Darstellung der damaligen chirurgischen Hernientherapie am Salzburger St. Johanns Spital. Ergänzend erfolgt ein Vergleich mit zeitgenössischen Veröffentlichungen zur Thematik der Hernienchirurgie, welche sich zum damaligen Zeitpunkt am Vorabend zur Asepsis bereits in einem Prozess des Umbruchs befand.
Herein described is the discovery of three novel types of dimeric naphthylisoquinoline alkaloids, named mbandakamines, cyclombandakamines, and spirombandakamines. They were found in the leaves of a botanically as yet unidentified, potentially new Ancistrocladus species, collected in the rainforest of the Democratic Republic of the Congo (DRC). Mbandakamines showed an exceptional 6′,1′′-coupling, in the peri-position neighboring one of the outer axes, leading to an extremely high steric hindrance at the central axis, and to U-turn-like molecular shape, which – different from all other dimeric NIQs, whose basic structures are all quite linear – brings three of the four bicyclic ring systems in close proximity to each other. This created an unprecedented follow-up chemistry, involving ring closure reactions, leading to two further, structurally even more intriguing subclasses, the cyclo- and the spirombandakamines, displaying eight stereogenic elements (the highest total number ever found in naphthylisoquinoline alkaloids). The metabolites exhibited pronounced antiplasmodial and antitrypanosomal activities. Likewise reported in this doctoral thesis are the isolation and structural elucidation of naphthylisoquinoline alkaloids from two further potentially new Ancistrocladus species from DRC. Some of these metabolites have shown pronounced antiausterity activities against human pancreatic cancer PANC-1 cells.
