    Authors: Luther, Robert;

    Von großen planetaren Einschlägen bis hinunter zu kleinsten Impakten auf Asteroiden laufen ähnliche Prozesse ab, deren Verständnis bedeutsam für zahlreiche darauf aufbauende Fragestellungen ist. In dieser Dissertation liegt der Fokus auf einem Teilaspekt der Kraterbildung – dem Materialauswurf. Kraterauswurfdecken sind typische Merkmale der allermeisten Krater im Sonnensystem. Zwar ist der eigentliche Prozess der zum Auswurf des Materials führt verstanden, aber eine systematische Untersuchung der Abhängigkeit der Auswurfcharakteristika (wie z.B. Geschwindigkeit oder Auswurfwinkel) von Materialeigenschaften ist noch nicht erfolgt. Ebenso fehlt eine systematische Untersuchung des Verhaltens des Auswurfmaterials in einem gasförmigen Medium. In dieser Dissertation greife ich auf numerische Methoden zurück, um Einschlagsprozesse zu simulieren. Das hierfür genutzte und von mir erweiterte Stoßwellensimulationsprogramm iSALE ist in der Fachliteratur etabliert und gut beschrieben. Insbesondere gehe ich auf die vorhandenen Festigkeitsparametrisierungen und das Porositätskompaktionsmodell ein, da sie für die folgenden systematischen Untersuchungen der Auswurfmassen grundlegend sind. Das Porositätskompaktionsmodell wird in einer Studie angewandt, um die Verdichtung von hochporösem Schnee unter Beaufschlagung durch ein Meteoritenfragment zu quantifizieren. In diesem Extremfall wird nahezu kein Material ausgeworfen. Das Festigkeitsmodell zur Beschreibung von Festgestein wird zur Simulation der Kraterbildung in Quarzit und Marmor eingesetzt, um die für die Materialexkavation relevanten Festigkeitsmodelle anhand von Laborvergleichen zu validieren. Eine auffallende Besonderheit des Marmors ist, dass er im Vergleich zu der erwarteten Kratergröße gemäß der einaxialen Druckfestigkeit (UCS) deutlich kleinere Krater aufweist. Der Effekt der dynamischen Verhärtung wird mit dem Festigkeitsmodell angenähert, um die experimentellen Krater nachzustellen. Auf den Materialmodellen aufbauend erfolgt die systematische Untersuchung des Verhaltens der Auswurfmassen, wobei hier erneut Labordaten experimenteller Krater zur Validierung herangezogen werden. Abhängig von verschiedenen Porositäten und Reibungskoeffizienten einer Parametrisierung der Festigkeit als Funktion des Druckes werden die Auswurfcharakteristika beschrieben und genutzt, um materialabhängige Auswurfdecken im Vakuum zu beschreiben. Außerdem werden analytische Skalierungsgesetze angewandt, um die entsprechenden Parameter basierend auf den Modelldaten zu bestimmen. Im folgenden Schritt wird dann die Wechselwirkung von Auswurfmaterial und einer vorhandenen Atmosphäre erläutert. Atmosphärische Effekte beeinflussen die ballistische Reichweite des ausgeworfenen Materials. Diese sind stark größenabhängig und die Reichweite nimmt mit kleiner werdenden Staubkorngrößen ab. In Bezug auf die Kratergröße nimmt die Reichweite ebenfalls ab, wenn die Kratergröße zunimmt. Zur Simulation und Beschreibung dieser Abhängigkeiten wurde ein neues Unterprogramm implementiert, in iSALE integriert und für eine systematische Parameterstudie herangezogen. Die Ergebnisse dieser Studie werden in dieser Arbeit dargestellt. (Deutsch) From large planetary impacts down to the smallest impacts on asteroids, similar processes take place, and understanding them is relevant for numerous further questions. In this thesis, I focus on one of the sub-aspects of crater formation, namely material ejection, as ejecta blankets are typical features of most craters in the solar system. Even though the basic process of ejection is understood, a systematic study on the correlation between ejection characteristics (e.g. ejection speed and angle) and material properties is still missing. Likewise, a systematic study on the behaviour of ejected material in a gaseous medium is lacking. In this thesis, I use a numerical approach to simulate impact processes. The used shock physics code iSALE, to which I added new features, is established in the literature and well described. Specifically, I focus on the strength models and the porosity-compaction model because the following systematic study of material ejection builds upon these models. The porosity-compaction model is applied in a study to quantify the compaction of highly porous snow after being impacted by meteorite fragments. In this end-member scenario, nearly no material is ejected. The strength model that is used for the representation of competent rock is applied to simulate craters in quartzite and marble in order to validate these rheology models, which are highly relevant for simulating excavation flow, against laboratory results. A striking characteristic observed for craters in marble is the smaller crater size compared to the expected crater size based on the uniaxial compressive strength (UCS) of marble. Here, I approximate the dynamic hardening of the marble target with the strength model of competent rock in order to reproduce the observed experimental craters. Based on these material models, I conduct a systematic parameter study on the behaviour of ejected material, which I again validate against laboratory data from experimental craters. Depending on material properties like porosity or the coefficient of friction for a parametrisation of the yield surface as function of pressure, the ejection characteristics are described and applied to derive the ejecta deposit in a vacuum case. In addition, analytical scaling relationships are fitted to the derived model data in order to obtain the corresponding parameters. In a next step, I explore the interaction of ejected material with an atmosphere. Atmospheric effects influence the ballistic range of the ejected material, and these effects are strongly size dependent, such that the range decreases with decreasing dust particle size. Further, relative to the crater size, the range decreases with increasing crater size. For the simulation and description of these correlations, a separate subroutine was written, integrated into iSALE, and applied for a systematic parameter study. The results of this study are presented in this thesis.

    Authors: Dostert, Astrid;

    Die Arbeit bietet die erste umfassende Rekonstruktion der Antikensammlung des französischen Kardinals Melchior de Polignac, beleuchtet ihre Entstehung im zweiten Viertel des 18. Jahrhunderts und untersucht deren zeitgenössische Rezeption in Künstler- und Gelehrtenkreisen. Schwerpunkte der Arbeit gelten dem Aufbau der Sammlung in Rom, ihrer Präsentation in Paris und ihrem Transfer nach Preußen. In einem Katalog werden alle Skulpturen dokumentiert, beschrieben und gedeutet, die im Zuge der Recherche identifiziert werden konnten. Soweit möglich sind alle Bildwerke im Tafelteil abgebildet. Kardinal de Polignac baute die Sammlung größtenteils während seines Aufenthalts in Rom als französischer Botschafter am päpstlichen Stuhl von 1724 bis 1732 auf, konnte sie dann nach Paris transferieren, wo sie in den beiden Hôtels particuliers, zunächst im Hôtel de Sully, dann im Hôtel de Mézières, dem Wohnsitz des Kardinals bis zu dessen Tod 1741, präsentiert wurde. 1742 wurde die Sammlung mit einem Verkaufskatalog auf dem Kunstmarkt angeboten und komplett von Friedrich II. von Preußen erworben. Kardinal de Polignac begeisterte sich für die antike Kunst und Kultur. Insbesondere antiken Skulpturen galt seine Sammelleidenschaft. Beim Aufbau seiner Sammlung profitierte der Kardinal von seinen engen Kontakten zu Gelehrten, Künstlern und Mäzenen. So führte Polignac selbst Grabungen in Rom und Umgebung durch und ließ die fragmentierten Skulpturen von talentierten Bildhauern restaurieren und dokumentieren. Außerdem förderte er die wissenschaftliche Beschäftigung mit den Antiken und stand im Austausch mit Gelehrten, Antiquaren und Sammlern. Unter Friedrich II. wurden in Berlin und Potsdam die rund 300 Objekte, vornehmlich Statuen, Büsten und Reliefs, darunter auch barocke und zeitgenössische Arbeiten, auf die seit 1742 entstehenden Schlossbauten und Gartenanlagen verteilt. Die hierbei leitenden Kriterien und Intentionen des preußischen Königs werden anhand der prominentesten Aufstellungskontexte wie dem Neuen Flügel von Schloss Charlottenburg, dem Schloss Sanssouci und der Bildergalerie sowie dem Antikentempel untersucht. Die vorliegende Rekonstruktion der Sammlung in ihren wechselnden Kontexten verdeutlicht ihre Bedeutung im 18. Jahrhundert und zeigt ihre Sonderstellung in Frankreich, insbesondere im Paris der 1730-er und 1740-er Jahre auf, sowie ihren Einfluss auf die friderizianischen Ausstattungskontexte. Darüber hinaus wird die Ergänzungspraxis der 1. Hälfte des 18. Jahrhunderts, die künstlerische sowie gelehrte Beschäftigung mit den Objekten untersucht und mit den parallel sich entwickelnden Methoden einer künftigen archäologischen Wissenschaft in Beziehung gesetzt. The thesis provides the first comprehensive reconstruction of the Collection of Antiquities of the French Cardinal Melchior de Polignac. It examines its origins in the second quarter of the 18th century and its influence on artists and scholars of the period. The thesis focuses on the collection’s formation in Rome, its presentation in Paris and its subsequent transfer to Prussia. All sculptures identified during research are listed, described and interpreted in the catalogue. If possible, the sculptures are represented in the plates. The reconstruction of the collection with reference to its changing contexts demonstrates the collection’s relevance in the 18th century and shows its singularity in France, especially in Paris during the 1730ies and 1740ies, as well as its influence on Prussian palace and garden decoration during the reign of Frederick II. The text investigates the practice of restoration of ancient sculpture during the first half of the 18th century as well as the artists’ and scholars’ approach to sculptures and antiquities in general taking into consideration the contemporaneous development of archaeology as a discipline.

    Authors: Mostajaboldave, Roxana Golsa;

    1.2 Abstract (Deutsch) 1.2.1 Ziele Trotz zahlreicher Studien die belegen, dass die selektive Kariesexkavation gegenüber der non-selektiven („vollständigen“) Kariesexkavation bei tiefen Läsionen vorteilhaft ist, bevorzugen die meisten Zahnärzte die non-selektive Kariesexkavation. Ein möglicher Grund hierfür könnte die Ablehnung der selektiven Kariesentfernung durch Patienten sein. Das Ziel dieser Studie war es, die Präferenzen von Patienten für eine der beiden Behandlungsmöglichkeiten zu erfragen. Des Weiteren wurde untersucht, welche Fakto-ren Einfluss auf die Entscheidungsfindung von Patienten bezüglich der Kariesexkavati-on haben. 1.2.2 Methoden Zur Erhebung der Daten wurde eine Kombination von qualitativen und quantitativen Vorgehensweisen im Sinne eines Mixed-Methods-Designs gewählt. Im Rahmen der qualitativen Studie wurden zwei Fokusgruppeninterviews durchgeführt. Die Diskussion wurde auf Tonband aufgenommen und anschließend anonymisiert und transkribiert. Die Transkripte wurden mittels Inhaltsanalyse nach Mayring ausgewertet. Die Ergebnisse der qualitativen Erhebung informierte das Design der quantitativen Studie. In dieser wurden 150 Teilnehmer befragt. Die Stichprobenauswahl erfolgte durch die Gelegenheitsstichprobenziehung (convenience sampling) und Klumpenauswahl (snow-ball sampling). Mittels Fallvignetten wurde die Relevanz von Behandlungsmerkmalen hinsichtlich der Präferenzen von Patienten bei der Wahl einer Behandlungsmöglichkeit ermittelt. Das umfasste das Risiko einer Nervschädigung, die Wurzelkanalbehandlung, wiederkehrende Karies, restaurative Komplikationen, Behandlungskosten und ästhetische Konsequenzen. Erfasst wurden außerdem Zahnarzterfahrung, Zahnarztangst, Persönlichkeitsmerkmale und die soziodemographischen Attribute. Mithilfe von Regressionsanalysen wurde der Zusammenhang zwischen den unabhängigen Merkmalen (Alter, Geschlecht, Bildungsstatus, Partnerschaftsstatus, Persönlichkeitsattribute, Zahnarzterfahrung, Ängstlichkeit) und den Behandlungspräferenzen (als abhängiges Merkmal) ermittelt. 1.2.3 Ergebnisse Die Teilnehmer der Fokusgruppen empfanden die vollständige Kariesexkavation als verlässlich, hatten jedoch Angst vor einer Wurzelkanalbehandlung. Die Mehrheit (82,7 %) der Teilnehmer unserer Fallvignettenumfrage bevorzugte die vollständige Kariesexkavation. Bei emotional stabilen Patienten (p < 0,001), jenen mit universitärem Abschluss (p < 0,001), Patienten mit keiner oder nur geringer Zahnarztangst (p = 0,04499), wenig Zahnarztwechseln in der Vergangenheit (p = 0,025) und solchen, die akzeptierten, dass versiegelte kariöse Läsionen voranschreiten könnten (p = 0,002), nahm die Präferenz zur selektiven Kariesentfernung signifikant zu. 1.2.4 Schlussfolgerungen Die Präferenzen der untersuchten Patienten bezüglich der Kariesexkavation wurden durch die Behandlungsattribute, durch soziodemographische Charakteristika, durch Persönlichkeitsmerkmale und durch Zahnarzterfahrungen geprägt. Although there are numerous studies which provide evidence that the selective removal of caries tissue has more advantages over the non-selective removal of caries tissue, the majority of dentists prefer non-selective removal of caries tissue. This could be due to the fact that patients might reject it.The aim of this study was to analyze patients' preferences for selective versus complete excavation, and to identify predictors of this preference. 1.1.2 Methods For the collection of data, we applied a sequential mixed-methods approach. In the first step, we performed semi-structured focus group discussions on two convenience samples. The discussions were recorded on audio. Subsequently the audio was transcribed. For the evaluation of the transcripts, qualitative content analysis was used. The results of the qualitative content analysis were used to design the quantitative study. 150 respondents participated in the quantitative study. For the recruitment of 150 respondents, convenience, snow-ball and deviant-case sampling were performed. By using case-vignettes the relevance of treatment attributes (risks of nerve damage, root-canal treatment, recurrent caries, restorative complications, treatment costs, aesthetic consequences) on patients' treatment preferences was measured. Furthermore, we captured patients' personality and socio-demographic details as well as dental experience and anxiety were recorded. By using regression analysis, the correlation between the predictor variables (age, gender, education, partnership status, personality items, dental experience, anxiety) and treatment preference was evaluated. 1.1.3 Results For the focus group participants, complete excavation was a reliable treatment option. But the majority of them feared endodontic treatment. The majority of the quantitative study participants (82.7%) preferred complete over selective excavation. In patients with an emotionally stable personality (p<0.001), university entrance degree (p<0.001), none or little dental anxiety (p=0.044), few dentist changes in the past (p=0.025), and who accepted that sealed lesions could progress (p<0.002) the preference for selective excavation was increased. 1.1.4 Conclusions Patients' preferences towards caries excavation were shaped by treatment attributes, socio-demographic characteristics, personality and dental experiences.

    Authors: Schwendicke, Falk;

    Das veränderte Verständnis von Karies spiegelt sich auch in einem veränderten Therapiekonzept wider: Statt einer rein symptomatischen Entfernung der kariösen Läsion wird vielmehr versucht, die Zusammensetzung und die metabolische Aktivität des dentalen Biofilms als Ursache der Erkrankung zu kontrollieren. Für tiefe Läsionen wird daher weniger auf eine vollständige Ausräumung des infizierten Dentins abgezielt, die wahrscheinlich durch Exkavation ohnehin nicht erreicht werden kann, sondern auf eine Kontrolle der Aktivität der Läsion. Dabei wird auf das Prinzip der Versiegelung der im Dentin verbleibenden Mikroorganismen zurückgegriffen: Versiegelte Bakterien sind von der Zufuhr mit Kohlenhydraten abgeschnitten, wodurch die Läsion inaktiviert wird. Der klassischen vollständigen Exkavation werden demnach Konzepte gegenübergestellt, die bewusst demineralisiertes bzw. infiziertes Dentin zeitweise oder dauerhaft unter einer Restauration belassen. Da bei letzterem Konzept in der Peripherie der Kavität andere (traditionelle) Exkavationskriterien als in Pulpanähe genutzt werden, wurde in der vorliegenden Arbeit der Begriff der selektiven Kariesexkavation zur Bezeichnung dieser Exkavationsstrategie genutzt. Die Wirksamkeit der selektiven Kariesexkavation und die möglichen positiven Langzeitfolgen sowie das gegenüber alternativen Exkavationsstrategien vorteilhafte Kosten- Wirksamkeits-Verhältnis wurden durch die durchgeführten Studien belegt. Bisher liegen jedoch wenige Studien mit patienten-zentrierten Ergebnissen vor, und vor allem die Umsetzung in der allgemeinzahnärztlichen Praxis ist nicht gegeben. Dafür sind Zweifel an der Arretierbarkeit kavitierter Läsionen und an der Stabilität und Integrität der Restauration verantwortlich, zudem herrscht Unsicherheit über den Umgang mit der röntgenologischen Sichtbarkeit von unter einer Restauration belassenen kariösen Läsionen: Diese könnten von anderen, nicht mit dem Verfahren der selektiven Exkavation vertrauten Zahnärzten als Behandlungsfehler angesehen und unnötigerweise nachbehandelt werden; zudem ist eine Abgrenzung von arretierten und progredienten belassenen Läsionen röntgenologisch nur schwer möglich. Letztlich steht eine Therapie wie die selektive Exkavation, bei der kariöses Dentin aktiv unter einer Restauration belassen wird, in Konflikt mit den Deutschland herrschenden Regulationen, was die Umsetzung in der Praxis zusätzlich behindert. In den durchgeführten Studien konnte gezeigt werden, dass selektiv statt vollständig exkavierte Zähne nicht zwingend mechanisch kompromittiert sind: Weder die Frakturresistenz noch die Integrität der zervikalen Restaurationsränder waren signifikant verschieden zwischen selektiv und vollständig exkavierten Zähnen in vitro. Dementsprechend konnten auch für die Anfälligkeit für Karies am Restaurationsrand und für die Mikroleakage zwischen Zahn und Restauration kein Unterschied zwischen verschieden exkavierten Zähnen gezeigt werden. Warum das belassene demineralisierte, weichere und weniger adhäsionsfreundliche Dentin keine signifikant nachteiligen Effekte auf die besagten Parameter hatte, konnte nicht geklärt werden, und basierend auf dem laborexperimentellen Charakter der Studien sind klinische Schlüsse nur begrenzt möglich. Weiterhin wurde ein Verfahren zur Markierung von bewusst im Rahmen einer selektiven Exkavation belassenen Läsionen entwickelt, dass auf röntgenopake Lösungen auf Zinnchloridbasis zurückgreift. Eine solche Markierung war geeignet, belassene Läsionen röntgenologisch zu maskieren; zudem war in vitro eine Abgrenzung aktiver und inaktiver Läsionen möglich. Die klinische Erprobung und die Klärung möglicher positiver oder nachteiliger Nebenwirkungen stehen aus. Ausgehend von den durchgeführten Studien sollten bereits angestoßene Diskussionsprozesse intensiviert werden, um sowohl emotionale als auch faktische Hürden bei der Umsetzung einer selektiven Exkavation in der zahnärztlichen Praxis abzubauen. Die Ergebnisse der dargestellten Studien sind geeignet, neue Perspektiven für laborexperimentelle und klinische Forschung aufzuzeigen und vorherrschende Therapiekonzepte kritisch gegenüber wissenschaftlicher Evidenz zu prüfen. An evolving understanding of caries is reflected by changing treatment concepts. Controlling the lesion and its activity has replaced mere lesion removal. Sealing caries lesions is increasingly seen as a valid option, with sealed bacteria inactivating due to nutritional deprivation. As a consequence, alternatives to the traditional "complete" removal of carious dentin are available, like stepwise or selective excavation. The latter strategy seals carious dentin beneath the restoration, and seems especially suitable for deep caries lesions, as the risks of pulpal exposures and complications might be reduced compared to the conventional approach. The evidence for this selective excavation is systematically appraised. The cost-effectiveness is assessed and study results extrapolated using economic models. It is assessed how dentists excavate deep lesions in German practices, and barriers of translating the benefits seen in scientific studies into daily practice are identified. Based on this, the fracture resistance and margin integrity of selectively compared with completely excavated teeth are assessed. Last, the diagnostic uncertainy associated with the radiolucency beneath the placed restoration, caused by the remaining demineralized dentin, is addressed.

    Radiocarbon dating of two bone samples from the archaeological excavation of the farm at Ain Wassel (High Tunisian Tell). The analysed material comes from the archaeological excavation at Ain Wassel carried out by the University of Trento (Italy) and the Institut National du Patrimoine of Tunisia, under the joint direction of Mustapha Khanoussi and Mariette de Vos Raaijmakers (1994- 1996). See: http://rusafricum.org/en/thuggasurvey/home/ The samples, a pork (KIA-55574) and a chicken (KIA-55575) bone, come from a fill layer including very mixed heretogeneous material dating to the Byzantine period and adhered to the wall of a ceramic vessel (closed form in common ware). The analysis have been carried out by the The Leibniz Laboratory for Radiometric Dating and Stable Isotope Research (AMS 14C Lab).

    Quantitative analyses of soil and sediment samples are often used to complement stratigraphic interpretations in archaeological and geoscientific research. The outcome of such analyses often is confined to small parts of the examined profiles as only a limited number of samples can be extracted and processed. Recent laboratory studies show that such selectively measured soil and sediment characteristics can be spatially extrapolated using spectral image data, resulting in reliable maps of a variety of parameters. However, on-site usage of this method has not been examined. We therefore explore, whether image data (RGB data and visible and near infrared hyperspectral data), acquired under regular fieldwork conditions during an archaeological excavation, in combination with a sampling strategy that is close to common practice, can be used to produce maps of soil organic matter, hematite, calcite, several weathering indices and grain size characteristics throughout complex archaeological profiles. We examine two profiles from an archaeological trench in Yeha (Tigray, Ethiopia). Our findings show a promising performance of RGB data and its derivative CIELAB as well as hyperspectral data for the prediction of parameters via random forest regression. By including two individual profiles we are able to assess the accuracy and reproducibility of our results, and illustrate the advantages and drawbacks of a higher spectral resolution and the necessary additional effort during fieldwork. The produced maps of the parameters examined allow us to critically reflect on the stratigraphic interpretation and offer a more objective basis for layer delineation in general. Our study therefore promotes more transparent and reproducible documentation for often destructive archaeological fieldwork.

    Objectives To compare the success, survival and costs of selective versus stepwise carious tissue removal (SE/SW) in permanent teeth with deep (>2/3 dentine depth) carious lesions. Design Randomised controlled, unicentre, clustered two-arm superiority trial. Setting Outpatient clinic of a private university in Cairo, Egypt. Participants One hundred and fifteen participants (n=132 teeth), aged 18–47 years, from Cairo, Egypt, were enrolled. Premolars/molars with occlusal/occlusal-proximal deep lesions (radiographically >2/3 dentine), sensible pulps, without spontaneous pain, were included. Interventions Peripheral carious tissue removal to hard dentine was performed. Pulpo-proximally, soft dentine was left. A glass ionomer (GI) restoration was placed. After 3–4 months, teeth were randomly allocated to SE (n=66), with reduction of the GI into a base and no further tissue removal, followed by a composite resin restoration, or SW (n=66), with full removal of the GI, additional excavation until firm dentine pulpo-proximally, followed by a GI-based composite restoration. Mean follow-up was 1 year. Primary and secondary outcome measures Primary outcome was success (absence of endodontic/restorative complications). Secondary outcomes were tooth survival and initial and total treatment costs. Results Zero/five pulp exposures occurred during SE/SW, and seven/five SE/SW teeth required endodontic therapy. Success after 12 months was 89.4% for SE and 84.9% for SW. The estimated mean time free of complications was 23 and 18 months for SE and SW, respectively, without significant differences between SE and SW (p>0.05/Cox). Initial treatment costs were significantly higher for SW (mean (SD): 507.5 (123.4) Egyptian pounds (EGP)) than SE (mean (SD): 456.6 (98.3) EGP), while total costs showed no significant difference (p>0.05). Conclusion Within the limitations of this interim analysis, and considering the depth of these lesions (>2/3 dentine), SE and SW showed similar risk of failure and overall costs after 1 year. Trial registration number PACTR201603001396248.

    The study of prehistoric textile production requires the excavation of sites with exceptional organic preservation. Here, the authors focus on thread production using evidence from two fourth-millennium BC pre-Alpine wetland sites: Arbon-Bleiche 3 in Switzerland and Bad Buchau-Torwiesen II in southern Germany. A comparison of the spindle whorls from these two settlements with a contemporaneous East-Central European dataset suggests that multiple culture-historical groups with distinct technological signatures inhabited Neolithic Central Europe. Furthermore, the spatial distribution of conical spindle whorls within the pre-Alpine settlements suggests the immigration of both people and technology from the east, thereby illuminating the wider themes of mobility and innovation in prehistoric Europe.

    Authors: Luther, Robert;

    Von großen planetaren Einschlägen bis hinunter zu kleinsten Impakten auf Asteroiden laufen ähnliche Prozesse ab, deren Verständnis bedeutsam für zahlreiche darauf aufbauende Fragestellungen ist. In dieser Dissertation liegt der Fokus auf einem Teilaspekt der Kraterbildung – dem Materialauswurf. Kraterauswurfdecken sind typische Merkmale der allermeisten Krater im Sonnensystem. Zwar ist der eigentliche Prozess der zum Auswurf des Materials führt verstanden, aber eine systematische Untersuchung der Abhängigkeit der Auswurfcharakteristika (wie z.B. Geschwindigkeit oder Auswurfwinkel) von Materialeigenschaften ist noch nicht erfolgt. Ebenso fehlt eine systematische Untersuchung des Verhaltens des Auswurfmaterials in einem gasförmigen Medium. In dieser Dissertation greife ich auf numerische Methoden zurück, um Einschlagsprozesse zu simulieren. Das hierfür genutzte und von mir erweiterte Stoßwellensimulationsprogramm iSALE ist in der Fachliteratur etabliert und gut beschrieben. Insbesondere gehe ich auf die vorhandenen Festigkeitsparametrisierungen und das Porositätskompaktionsmodell ein, da sie für die folgenden systematischen Untersuchungen der Auswurfmassen grundlegend sind. Das Porositätskompaktionsmodell wird in einer Studie angewandt, um die Verdichtung von hochporösem Schnee unter Beaufschlagung durch ein Meteoritenfragment zu quantifizieren. In diesem Extremfall wird nahezu kein Material ausgeworfen. Das Festigkeitsmodell zur Beschreibung von Festgestein wird zur Simulation der Kraterbildung in Quarzit und Marmor eingesetzt, um die für die Materialexkavation relevanten Festigkeitsmodelle anhand von Laborvergleichen zu validieren. Eine auffallende Besonderheit des Marmors ist, dass er im Vergleich zu der erwarteten Kratergröße gemäß der einaxialen Druckfestigkeit (UCS) deutlich kleinere Krater aufweist. Der Effekt der dynamischen Verhärtung wird mit dem Festigkeitsmodell angenähert, um die experimentellen Krater nachzustellen. Auf den Materialmodellen aufbauend erfolgt die systematische Untersuchung des Verhaltens der Auswurfmassen, wobei hier erneut Labordaten experimenteller Krater zur Validierung herangezogen werden. Abhängig von verschiedenen Porositäten und Reibungskoeffizienten einer Parametrisierung der Festigkeit als Funktion des Druckes werden die Auswurfcharakteristika beschrieben und genutzt, um materialabhängige Auswurfdecken im Vakuum zu beschreiben. Außerdem werden analytische Skalierungsgesetze angewandt, um die entsprechenden Parameter basierend auf den Modelldaten zu bestimmen. Im folgenden Schritt wird dann die Wechselwirkung von Auswurfmaterial und einer vorhandenen Atmosphäre erläutert. Atmosphärische Effekte beeinflussen die ballistische Reichweite des ausgeworfenen Materials. Diese sind stark größenabhängig und die Reichweite nimmt mit kleiner werdenden Staubkorngrößen ab. In Bezug auf die Kratergröße nimmt die Reichweite ebenfalls ab, wenn die Kratergröße zunimmt. Zur Simulation und Beschreibung dieser Abhängigkeiten wurde ein neues Unterprogramm implementiert, in iSALE integriert und für eine systematische Parameterstudie herangezogen. Die Ergebnisse dieser Studie werden in dieser Arbeit dargestellt. (Deutsch) From large planetary impacts down to the smallest impacts on asteroids, similar processes take place, and understanding them is relevant for numerous further questions. In this thesis, I focus on one of the sub-aspects of crater formation, namely material ejection, as ejecta blankets are typical features of most craters in the solar system. Even though the basic process of ejection is understood, a systematic study on the correlation between ejection characteristics (e.g. ejection speed and angle) and material properties is still missing. Likewise, a systematic study on the behaviour of ejected material in a gaseous medium is lacking. In this thesis, I use a numerical approach to simulate impact processes. The used shock physics code iSALE, to which I added new features, is established in the literature and well described. Specifically, I focus on the strength models and the porosity-compaction model because the following systematic study of material ejection builds upon these models. The porosity-compaction model is applied in a study to quantify the compaction of highly porous snow after being impacted by meteorite fragments. In this end-member scenario, nearly no material is ejected. The strength model that is used for the representation of competent rock is applied to simulate craters in quartzite and marble in order to validate these rheology models, which are highly relevant for simulating excavation flow, against laboratory results. A striking characteristic observed for craters in marble is the smaller crater size compared to the expected crater size based on the uniaxial compressive strength (UCS) of marble. Here, I approximate the dynamic hardening of the marble target with the strength model of competent rock in order to reproduce the observed experimental craters. Based on these material models, I conduct a systematic parameter study on the behaviour of ejected material, which I again validate against laboratory data from experimental craters. Depending on material properties like porosity or the coefficient of friction for a parametrisation of the yield surface as function of pressure, the ejection characteristics are described and applied to derive the ejecta deposit in a vacuum case. In addition, analytical scaling relationships are fitted to the derived model data in order to obtain the corresponding parameters. In a next step, I explore the interaction of ejected material with an atmosphere. Atmospheric effects influence the ballistic range of the ejected material, and these effects are strongly size dependent, such that the range decreases with decreasing dust particle size. Further, relative to the crater size, the range decreases with increasing crater size. For the simulation and description of these correlations, a separate subroutine was written, integrated into iSALE, and applied for a systematic parameter study. The results of this study are presented in this thesis.

    Authors: Dostert, Astrid;

    Die Arbeit bietet die erste umfassende Rekonstruktion der Antikensammlung des französischen Kardinals Melchior de Polignac, beleuchtet ihre Entstehung im zweiten Viertel des 18. Jahrhunderts und untersucht deren zeitgenössische Rezeption in Künstler- und Gelehrtenkreisen. Schwerpunkte der Arbeit gelten dem Aufbau der Sammlung in Rom, ihrer Präsentation in Paris und ihrem Transfer nach Preußen. In einem Katalog werden alle Skulpturen dokumentiert, beschrieben und gedeutet, die im Zuge der Recherche identifiziert werden konnten. Soweit möglich sind alle Bildwerke im Tafelteil abgebildet. Kardinal de Polignac baute die Sammlung größtenteils während seines Aufenthalts in Rom als französischer Botschafter am päpstlichen Stuhl von 1724 bis 1732 auf, konnte sie dann nach Paris transferieren, wo sie in den beiden Hôtels particuliers, zunächst im Hôtel de Sully, dann im Hôtel de Mézières, dem Wohnsitz des Kardinals bis zu dessen Tod 1741, präsentiert wurde. 1742 wurde die Sammlung mit einem Verkaufskatalog auf dem Kunstmarkt angeboten und komplett von Friedrich II. von Preußen erworben. Kardinal de Polignac begeisterte sich für die antike Kunst und Kultur. Insbesondere antiken Skulpturen galt seine Sammelleidenschaft. Beim Aufbau seiner Sammlung profitierte der Kardinal von seinen engen Kontakten zu Gelehrten, Künstlern und Mäzenen. So führte Polignac selbst Grabungen in Rom und Umgebung durch und ließ die fragmentierten Skulpturen von talentierten Bildhauern restaurieren und dokumentieren. Außerdem förderte er die wissenschaftliche Beschäftigung mit den Antiken und stand im Austausch mit Gelehrten, Antiquaren und Sammlern. Unter Friedrich II. wurden in Berlin und Potsdam die rund 300 Objekte, vornehmlich Statuen, Büsten und Reliefs, darunter auch barocke und zeitgenössische Arbeiten, auf die seit 1742 entstehenden Schlossbauten und Gartenanlagen verteilt. Die hierbei leitenden Kriterien und Intentionen des preußischen Königs werden anhand der prominentesten Aufstellungskontexte wie dem Neuen Flügel von Schloss Charlottenburg, dem Schloss Sanssouci und der Bildergalerie sowie dem Antikentempel untersucht. Die vorliegende Rekonstruktion der Sammlung in ihren wechselnden Kontexten verdeutlicht ihre Bedeutung im 18. Jahrhundert und zeigt ihre Sonderstellung in Frankreich, insbesondere im Paris der 1730-er und 1740-er Jahre auf, sowie ihren Einfluss auf die friderizianischen Ausstattungskontexte. Darüber hinaus wird die Ergänzungspraxis der 1. Hälfte des 18. Jahrhunderts, die künstlerische sowie gelehrte Beschäftigung mit den Objekten untersucht und mit den parallel sich entwickelnden Methoden einer künftigen archäologischen Wissenschaft in Beziehung gesetzt. The thesis provides the first comprehensive reconstruction of the Collection of Antiquities of the French Cardinal Melchior de Polignac. It examines its origins in the second quarter of the 18th century and its influence on artists and scholars of the period. The thesis focuses on the collection’s formation in Rome, its presentation in Paris and its subsequent transfer to Prussia. All sculptures identified during research are listed, described and interpreted in the catalogue. If possible, the sculptures are represented in the plates. The reconstruction of the collection with reference to its changing contexts demonstrates the collection’s relevance in the 18th century and shows its singularity in France, especially in Paris during the 1730ies and 1740ies, as well as its influence on Prussian palace and garden decoration during the reign of Frederick II. The text investigates the practice of restoration of ancient sculpture during the first half of the 18th century as well as the artists’ and scholars’ approach to sculptures and antiquities in general taking into consideration the contemporaneous development of archaeology as a discipline.

    1.2 Abstract (Deutsch) 1.2.1 Ziele Trotz zahlreicher Studien die belegen, dass die selektive Kariesexkavation gegenüber der non-selektiven („vollständigen“) Kariesexkavation bei tiefen Läsionen vorteilhaft ist, bevorzugen die meisten Zahnärzte die non-selektive Kariesexkavation. Ein möglicher Grund hierfür könnte die Ablehnung der selektiven Kariesentfernung durch Patienten sein. Das Ziel dieser Studie war es, die Präferenzen von Patienten für eine der beiden Behandlungsmöglichkeiten zu erfragen. Des Weiteren wurde untersucht, welche Fakto-ren Einfluss auf die Entscheidungsfindung von Patienten bezüglich der Kariesexkavati-on haben. 1.2.2 Methoden Zur Erhebung der Daten wurde eine Kombination von qualitativen und quantitativen Vorgehensweisen im Sinne eines Mixed-Methods-Designs gewählt. Im Rahmen der qualitativen Studie wurden zwei Fokusgruppeninterviews durchgeführt. Die Diskussion wurde auf Tonband aufgenommen und anschließend anonymisiert und transkribiert. Die Transkripte wurden mittels Inhaltsanalyse nach Mayring ausgewertet. Die Ergebnisse der qualitativen Erhebung informierte das Design der quantitativen Studie. In dieser wurden 150 Teilnehmer befragt. Die Stichprobenauswahl erfolgte durch die Gelegenheitsstichprobenziehung (convenience sampling) und Klumpenauswahl (snow-ball sampling). Mittels Fallvignetten wurde die Relevanz von Behandlungsmerkmalen hinsichtlich der Präferenzen von Patienten bei der Wahl einer Behandlungsmöglichkeit ermittelt. Das umfasste das Risiko einer Nervschädigung, die Wurzelkanalbehandlung, wiederkehrende Karies, restaurative Komplikationen, Behandlungskosten und ästhetische Konsequenzen. Erfasst wurden außerdem Zahnarzterfahrung, Zahnarztangst, Persönlichkeitsmerkmale und die soziodemographischen Attribute. Mithilfe von Regressionsanalysen wurde der Zusammenhang zwischen den unabhängigen Merkmalen (Alter, Geschlecht, Bildungsstatus, Partnerschaftsstatus, Persönlichkeitsattribute, Zahnarzterfahrung, Ängstlichkeit) und den Behandlungspräferenzen (als abhängiges Merkmal) ermittelt. 1.2.3 Ergebnisse Die Teilnehmer der Fokusgruppen empfanden die vollständige Kariesexkavation als verlässlich, hatten jedoch Angst vor einer Wurzelkanalbehandlung. Die Mehrheit (82,7 %) der Teilnehmer unserer Fallvignettenumfrage bevorzugte die vollständige Kariesexkavation. Bei emotional stabilen Patienten (p < 0,001), jenen mit universitärem Abschluss (p < 0,001), Patienten mit keiner oder nur geringer Zahnarztangst (p = 0,04499), wenig Zahnarztwechseln in der Vergangenheit (p = 0,025) und solchen, die akzeptierten, dass versiegelte kariöse Läsionen voranschreiten könnten (p = 0,002), nahm die Präferenz zur selektiven Kariesentfernung signifikant zu. 1.2.4 Schlussfolgerungen Die Präferenzen der untersuchten Patienten bezüglich der Kariesexkavation wurden durch die Behandlungsattribute, durch soziodemographische Charakteristika, durch Persönlichkeitsmerkmale und durch Zahnarzterfahrungen geprägt. Although there are numerous studies which provide evidence that the selective removal of caries tissue has more advantages over the non-selective removal of caries tissue, the majority of dentists prefer non-selective removal of caries tissue. This could be due to the fact that patients might reject it.The aim of this study was to analyze patients' preferences for selective versus complete excavation, and to identify predictors of this preference. 1.1.2 Methods For the collection of data, we applied a sequential mixed-methods approach. In the first step, we performed semi-structured focus group discussions on two convenience samples. The discussions were recorded on audio. Subsequently the audio was transcribed. For the evaluation of the transcripts, qualitative content analysis was used. The results of the qualitative content analysis were used to design the quantitative study. 150 respondents participated in the quantitative study. For the recruitment of 150 respondents, convenience, snow-ball and deviant-case sampling were performed. By using case-vignettes the relevance of treatment attributes (risks of nerve damage, root-canal treatment, recurrent caries, restorative complications, treatment costs, aesthetic consequences) on patients' treatment preferences was measured. Furthermore, we captured patients' personality and socio-demographic details as well as dental experience and anxiety were recorded. By using regression analysis, the correlation between the predictor variables (age, gender, education, partnership status, personality items, dental experience, anxiety) and treatment preference was evaluated. 1.1.3 Results For the focus group participants, complete excavation was a reliable treatment option. But the majority of them feared endodontic treatment. The majority of the quantitative study participants (82.7%) preferred complete over selective excavation. In patients with an emotionally stable personality (p<0.001), university entrance degree (p<0.001), none or little dental anxiety (p=0.044), few dentist changes in the past (p=0.025), and who accepted that sealed lesions could progress (p<0.002) the preference for selective excavation was increased. 1.1.4 Conclusions Patients' preferences towards caries excavation were shaped by treatment attributes, socio-demographic characteristics, personality and dental experiences.

    Authors: Schwendicke, Falk;

    Das veränderte Verständnis von Karies spiegelt sich auch in einem veränderten Therapiekonzept wider: Statt einer rein symptomatischen Entfernung der kariösen Läsion wird vielmehr versucht, die Zusammensetzung und die metabolische Aktivität des dentalen Biofilms als Ursache der Erkrankung zu kontrollieren. Für tiefe Läsionen wird daher weniger auf eine vollständige Ausräumung des infizierten Dentins abgezielt, die wahrscheinlich durch Exkavation ohnehin nicht erreicht werden kann, sondern auf eine Kontrolle der Aktivität der Läsion. Dabei wird auf das Prinzip der Versiegelung der im Dentin verbleibenden Mikroorganismen zurückgegriffen: Versiegelte Bakterien sind von der Zufuhr mit Kohlenhydraten abgeschnitten, wodurch die Läsion inaktiviert wird. Der klassischen vollständigen Exkavation werden demnach Konzepte gegenübergestellt, die bewusst demineralisiertes bzw. infiziertes Dentin zeitweise oder dauerhaft unter einer Restauration belassen. Da bei letzterem Konzept in der Peripherie der Kavität andere (traditionelle) Exkavationskriterien als in Pulpanähe genutzt werden, wurde in der vorliegenden Arbeit der Begriff der selektiven Kariesexkavation zur Bezeichnung dieser Exkavationsstrategie genutzt. Die Wirksamkeit der selektiven Kariesexkavation und die möglichen positiven Langzeitfolgen sowie das gegenüber alternativen Exkavationsstrategien vorteilhafte Kosten- Wirksamkeits-Verhältnis wurden durch die durchgeführten Studien belegt. Bisher liegen jedoch wenige Studien mit patienten-zentrierten Ergebnissen vor, und vor allem die Umsetzung in der allgemeinzahnärztlichen Praxis ist nicht gegeben. Dafür sind Zweifel an der Arretierbarkeit kavitierter Läsionen und an der Stabilität und Integrität der Restauration verantwortlich, zudem herrscht Unsicherheit über den Umgang mit der röntgenologischen Sichtbarkeit von unter einer Restauration belassenen kariösen Läsionen: Diese könnten von anderen, nicht mit dem Verfahren der selektiven Exkavation vertrauten Zahnärzten als Behandlungsfehler angesehen und unnötigerweise nachbehandelt werden; zudem ist eine Abgrenzung von arretierten und progredienten belassenen Läsionen röntgenologisch nur schwer möglich. Letztlich steht eine Therapie wie die selektive Exkavation, bei der kariöses Dentin aktiv unter einer Restauration belassen wird, in Konflikt mit den Deutschland herrschenden Regulationen, was die Umsetzung in der Praxis zusätzlich behindert. In den durchgeführten Studien konnte gezeigt werden, dass selektiv statt vollständig exkavierte Zähne nicht zwingend mechanisch kompromittiert sind: Weder die Frakturresistenz noch die Integrität der zervikalen Restaurationsränder waren signifikant verschieden zwischen selektiv und vollständig exkavierten Zähnen in vitro. Dementsprechend konnten auch für die Anfälligkeit für Karies am Restaurationsrand und für die Mikroleakage zwischen Zahn und Restauration kein Unterschied zwischen verschieden exkavierten Zähnen gezeigt werden. Warum das belassene demineralisierte, weichere und weniger adhäsionsfreundliche Dentin keine signifikant nachteiligen Effekte auf die besagten Parameter hatte, konnte nicht geklärt werden, und basierend auf dem laborexperimentellen Charakter der Studien sind klinische Schlüsse nur begrenzt möglich. Weiterhin wurde ein Verfahren zur Markierung von bewusst im Rahmen einer selektiven Exkavation belassenen Läsionen entwickelt, dass auf röntgenopake Lösungen auf Zinnchloridbasis zurückgreift. Eine solche Markierung war geeignet, belassene Läsionen röntgenologisch zu maskieren; zudem war in vitro eine Abgrenzung aktiver und inaktiver Läsionen möglich. Die klinische Erprobung und die Klärung möglicher positiver oder nachteiliger Nebenwirkungen stehen aus. Ausgehend von den durchgeführten Studien sollten bereits angestoßene Diskussionsprozesse intensiviert werden, um sowohl emotionale als auch faktische Hürden bei der Umsetzung einer selektiven Exkavation in der zahnärztlichen Praxis abzubauen. Die Ergebnisse der dargestellten Studien sind geeignet, neue Perspektiven für laborexperimentelle und klinische Forschung aufzuzeigen und vorherrschende Therapiekonzepte kritisch gegenüber wissenschaftlicher Evidenz zu prüfen. An evolving understanding of caries is reflected by changing treatment concepts. Controlling the lesion and its activity has replaced mere lesion removal. Sealing caries lesions is increasingly seen as a valid option, with sealed bacteria inactivating due to nutritional deprivation. As a consequence, alternatives to the traditional "complete" removal of carious dentin are available, like stepwise or selective excavation. The latter strategy seals carious dentin beneath the restoration, and seems especially suitable for deep caries lesions, as the risks of pulpal exposures and complications might be reduced compared to the conventional approach. The evidence for this selective excavation is systematically appraised. The cost-effectiveness is assessed and study results extrapolated using economic models. It is assessed how dentists excavate deep lesions in German practices, and barriers of translating the benefits seen in scientific studies into daily practice are identified. Based on this, the fracture resistance and margin integrity of selectively compared with completely excavated teeth are assessed. Last, the diagnostic uncertainy associated with the radiolucency beneath the placed restoration, caused by the remaining demineralized dentin, is addressed.

    Radiocarbon dating of two bone samples from the archaeological excavation of the farm at Ain Wassel (High Tunisian Tell). The analysed material comes from the archaeological excavation at Ain Wassel carried out by the University of Trento (Italy) and the Institut National du Patrimoine of Tunisia, under the joint direction of Mustapha Khanoussi and Mariette de Vos Raaijmakers (1994- 1996). See: http://rusafricum.org/en/thuggasurvey/home/ The samples, a pork (KIA-55574) and a chicken (KIA-55575) bone, come from a fill layer including very mixed heretogeneous material dating to the Byzantine period and adhered to the wall of a ceramic vessel (closed form in common ware). The analysis have been carried out by the The Leibniz Laboratory for Radiometric Dating and Stable Isotope Research (AMS 14C Lab).

    Quantitative analyses of soil and sediment samples are often used to complement stratigraphic interpretations in archaeological and geoscientific research. The outcome of such analyses often is confined to small parts of the examined profiles as only a limited number of samples can be extracted and processed. Recent laboratory studies show that such selectively measured soil and sediment characteristics can be spatially extrapolated using spectral image data, resulting in reliable maps of a variety of parameters. However, on-site usage of this method has not been examined. We therefore explore, whether image data (RGB data and visible and near infrared hyperspectral data), acquired under regular fieldwork conditions during an archaeological excavation, in combination with a sampling strategy that is close to common practice, can be used to produce maps of soil organic matter, hematite, calcite, several weathering indices and grain size characteristics throughout complex archaeological profiles. We examine two profiles from an archaeological trench in Yeha (Tigray, Ethiopia). Our findings show a promising performance of RGB data and its derivative CIELAB as well as hyperspectral data for the prediction of parameters via random forest regression. By including two individual profiles we are able to assess the accuracy and reproducibility of our results, and illustrate the advantages and drawbacks of a higher spectral resolution and the necessary additional effort during fieldwork. The produced maps of the parameters examined allow us to critically reflect on the stratigraphic interpretation and offer a more objective basis for layer delineation in general. Our study therefore promotes more transparent and reproducible documentation for often destructive archaeological fieldwork.

    Objectives To compare the success, survival and costs of selective versus stepwise carious tissue removal (SE/SW) in permanent teeth with deep (>2/3 dentine depth) carious lesions. Design Randomised controlled, unicentre, clustered two-arm superiority trial. Setting Outpatient clinic of a private university in Cairo, Egypt. Participants One hundred and fifteen participants (n=132 teeth), aged 18–47 years, from Cairo, Egypt, were enrolled. Premolars/molars with occlusal/occlusal-proximal deep lesions (radiographically >2/3 dentine), sensible pulps, without spontaneous pain, were included. Interventions Peripheral carious tissue removal to hard dentine was performed. Pulpo-proximally, soft dentine was left. A glass ionomer (GI) restoration was placed. After 3–4 months, teeth were randomly allocated to SE (n=66), with reduction of the GI into a base and no further tissue removal, followed by a composite resin restoration, or SW (n=66), with full removal of the GI, additional excavation until firm dentine pulpo-proximally, followed by a GI-based composite restoration. Mean follow-up was 1 year. Primary and secondary outcome measures Primary outcome was success (absence of endodontic/restorative complications). Secondary outcomes were tooth survival and initial and total treatment costs. Results Zero/five pulp exposures occurred during SE/SW, and seven/five SE/SW teeth required endodontic therapy. Success after 12 months was 89.4% for SE and 84.9% for SW. The estimated mean time free of complications was 23 and 18 months for SE and SW, respectively, without significant differences between SE and SW (p>0.05/Cox). Initial treatment costs were significantly higher for SW (mean (SD): 507.5 (123.4) Egyptian pounds (EGP)) than SE (mean (SD): 456.6 (98.3) EGP), while total costs showed no significant difference (p>0.05). Conclusion Within the limitations of this interim analysis, and considering the depth of these lesions (>2/3 dentine), SE and SW showed similar risk of failure and overall costs after 1 year. Trial registration number PACTR201603001396248.

    The study of prehistoric textile production requires the excavation of sites with exceptional organic preservation. Here, the authors focus on thread production using evidence from two fourth-millennium BC pre-Alpine wetland sites: Arbon-Bleiche 3 in Switzerland and Bad Buchau-Torwiesen II in southern Germany. A comparison of the spindle whorls from these two settlements with a contemporaneous East-Central European dataset suggests that multiple culture-historical groups with distinct technological signatures inhabited Neolithic Central Europe. Furthermore, the spatial distribution of conical spindle whorls within the pre-Alpine settlements suggests the immigration of both people and technology from the east, thereby illuminating the wider themes of mobility and innovation in prehistoric Europe.
