Jurassic to Lower Cretaceous tectonostratigraphy of the German Central Graben, southern North Sea

The Central Graben is a Mesozoic sedimentary basin that is significantly influenced by rift and salt tectonics. Its southern part is located in the German and Dutch sectors of the North Sea. Even though studies exist on the tectonic and stratigraphic development of the Danish and Dutch Central Graben, the German Central Graben as an important link is less investigated. We aim to fill this gap and to investigate the sedimentary development from the Latest Triassic to the Early Cretaceous, the relative influence of salt and rift tectonics on subsidence and how our results fit into the existing studies of the Danish and Dutch Central Graben. Knowledge of the development of the graben and its sedimentation is critical for any possible economic use like hydrocarbon exploitation or carbon capture and storage. Therefore, we mapped nine laterally traceable horizons on 2D and 3D reflection seismic data from the Lower Jurassic to the Lower Cretaceous within the German Central Graben and adjacent Danish Salt Dome Province as well as the northern Dutch Central Graben. These horizons include the base horizons of four tectonostratigraphic mega-sequences of the southern Central Graben adopted from the current Dutch tectonostratigraphic concept. Based on the mapping results, we constructed subsidence, thickness and erosion maps of the tectonostratigraphic mega-sequences and their subdivisions. The tectonostratigraphic mega-sequences were then correlated with well logs to determine the lithology. The results show that the structural and stratigraphic architecture of the German Central Graben was consecutively dominated by either subsidence controlled by rifting, salt tectonics or by thermal uplift and subsidence. We suggest that the German Central Graben is divided by a large strike-slip fault zone, the Mid Central Graben Transverse Zone, into a northern part that geologically rather belongs to the Danish and a southern part that rather belongs to the Dutch Central Graben. We discuss how this division and the tectonics influenced the regional lithology

Migration von /sw vom AFS ins DCE/DFS

/sw ist eine verteilte Softwarebereitstellung mit dem Ziel, jedem Benutzer Software zentral zur Verfügung zu stellen, ohne daß er sich darum kümmern muß, woher er seine Software bekommt. Für eine Außenstehenden ergibt sich somit das Bild eines großen Softwarepools, aus dem er sich fertig installierte Software für seine Plattform herunterladen kann. Voraussetzung dafür ist, daß ein Benuzter an seiner Workstation über AFS (Andrew File System), DFS (Distributed File System) oder ftp verfügt. Zur Zeit werden vom /sw für 18 verschiedenen Unix-Plattformen 594 Programme in 1024 verschiedenen Installationen angeboten. Die meisten Architekturen vom /sw liegen im AFS, bis auf die Architekturen DEC ALPHA, IRIX 4.0 und Linux, die im NFS liegen. In Zukunft wird es für die gesamte /sw Software nur noch eine Quelle geben, das DFS. Mit der Migration von /sw aus dem AFS ins DFS entfällt dann die Trennung von /sw in einen AFS-Teil und einem NFS-Teil und damit auch der AFS/NFS-Translators, der recht unstabil läuft. Die gesamte Software von /sw wurde aus dem AFS bzw. NFS ins DFS migriert, so daß für alle vom /sw unterstützten Architekturen nur noch eine Quelle zur Verfügung steht, die Stuttgarter DCE-Zelle. Jeder AFS-Klient hat über den AFS/DFS-Translator Zugriff auf /sw und für die NFS-Klienten wird das /sw-Fi-lesystem exportiert, so daß jeder NFS-Klient die Möglichkeit hat das DFS-Filesystem /sw zu mounten. Eine Workstation kann sowohl AFS- als auch DCE/DFS-Klient sein

The Incidence, Survival, and HPV Impact of Second Primary Cancer following Primary Oropharyngeal Squamous Cell Carcinoma: A 20-Year Retrospective and Population-Based Study

Second primary cancer (SPC) is the second most common cause of death among patients diagnosed with head and neck cancer. This study examined the risk of SPC following oropharyngeal squamous cell carcinoma (OPSCC) and the impact of human papillomavirus (HPV) on survival following SPC. The study was a population-based, retrospective study including all patients diagnosed with OPSCC in eastern Denmark from 2000–2020 who received curative intended treatment. The incidence rate ratio (IRR), age-adjusted incidence rates (AAIR), and hazard ratios (HR) were calculated. A total of 2584 patients with primary OPSCC were included (median follow-up time: 3.1 years), with 317 patients (12.3%) diagnosed with SPC. The risk of SPC was approximately five times the occurrence of cancer in the general population (IRR: 4.96). The median time to SPC after a primary OPSCC was 2.0 years (interquartile range (IQR) = 0.6–4.2 years). HPV-positive (HPV+) patients had a significantly longer median time to SPC, and a significant better survival compared to HPV-negative (HPV-) patients. SPC was most frequently found in lungs, head, and neck (LHN) for HPV- OPSCC patients and lungs followed by gender-specific (prostate, ovaries, or endometrium) for HPV+ OPSCC. There was a significant difference between the two groups when distributed between “within” or “outside” LHN. Patients with SPC outside LHN had a significant better overall survival. This knowledge should be considered during post-treatment surveillance and might guide targeted imaging
