In this study, we try to combine traditional archaeozoological biometry, based on outer bone measurements, with stable isotope analyses of bone collagen. Right from the start of archaeozoological research in Central and Western Europe, the important size variability in Roman domestic cattle has puzzled scholars. According to an established view, these differences in bone size are attributed either to the simultaneous presence of different types or even breeds or to the result of crossbreeding of smaller, native, and larger Roman cattle.

Objective: To determine whether a lower serum potassium concentration trigger for supplementation is noninferior to a high-normal trigger.
Design, Setting, And Participants: This open-label, noninferiority, randomized clinical trial was conducted at 23 cardiac surgical centers in the United Kingdom and Germany.
Background: The 7th National Audit Project of the Royal College of Anaesthetists studied peri-operative cardiac arrest because of existing knowledge gaps in this important topic. This applies in particular to cardiology patients receiving anaesthetic care, because numbers, types and complexity of minimally invasive interventional procedures requiring planned and unplanned anaesthesia in the cardiac intervention suite is increasing.
Methods: We analysed collected data to determine the epidemiology, clinical features, management and outcomes of peri-operative cardiac arrest in adult patients receiving anaesthetic care for cardiology procedures.
