Changes in emergency department utilisation in Germany before and during different phases of the Covid-19 pandemic, using data from a national surveillance system up to June 2021
The number of emergency department consultations decreased rapidly during the COVID-19 pandemic, without extensive variation in the distribution of patient characteristics. Smallest changes were observed for the most severe consultations and older age groups, which is especially reassuring regarding concerns of possible long-term complications due to patients avoiding urgent emergency care during the pandemic
Fold, Twist, and Draw – Techniques of Copper Alloy Wire Production from Hellenistic Jebel Khalid
Copper alloy wire fragments were examined using XRF , optical light microscopy and SEM-EDS . The specimens come from archaeological excavations at Jebel Khalid in Syria, dating from the 3rd century BCE (the Hellenistic period) to the Roman period. Our results show that several techniques were employed to make the wires: forging, folding, strip twisting, and possibly ‘strip drawing’. We investigated the morphologies, treatments, and fabrications a…
Are We Prepared for the Next Pandemic? Management, Systematic Evaluation and Lessons Learned from an In-Hospital Covid-19 Vaccination Centre for Healthcare Workers
staff numbers and process time per person were reduced several times during the first vaccination campaign. Lessons concerning appointment scheduling were learned. HCWs vaccinated at the in-hospital centre were satisfied with the process. A longer waiting time between admission and inoculation, perceived dissatisfying accessibility as well as an increased frequency of observed adverse events were linked to a reduced satisfaction. Comparatively su…

Radiocarbon Analysis on the New Aarams 1MV Tandetron
We report here on the radiocarbon performance on the AARAMS HVE 1MV Tandetron. 14 C analysis is carried out in charge state 2+. We have avoided Li interference by appropriate settings of the high-energy electrostatic analyzer and the 30° second high-energy magnet. The 14 C machine background is determined using unprocessed graphite, which yielded 58,650±2032 14 C yr determined as the average and standard deviation of four measurements. Internatio…

High-Current 14C Measurements on an HVE 1MV AMS System
High radiocarbon sample throughput is an increasingly important requirement of accelerator mass spectrometry (AMS) systems, which in turn requires high source output. To accomplish this, HVE AMS systems use a model SO-110B ion source, which can run at outputs of more than 200 μA 12C. It is known that high source output may compromise precision. To quantify this effect, we have tested an HVE 1MV AMS system for the influence of medium (100 μA) and …
