Timber supply through time - Copenhagen waterfronts under scrutiny.

Dendrochronology is not a new method for attaining high-precision dates for archaeological and historic remains of timber. But the extent to which dendrochronology is utilized to attain detailed precision of the dating of complex wooden structures can suffer from the fact that the method is often applied in commercial archaeology, where the extent of analysis is severely limited by cost constraints. Instead of lamenting the potentially lost levels of detail that might have slipped through over the years, it is hoped that by presenting the potential of high chronological precision, that necessitates extensive sampling of timber and wood remains on archaeological sites, a new future will be promoted, in which new wide-ranging sampling strategies will become a more normal practice in archaeology, in both the research and commercial spheres.

Paediatric dermatology teleconsultations: a survey of healthcare professionals in the UK.

The COVID-19 pandemic catapulted dermatology services into a digital era, with the rapid introduction of teleconsultations. The UK National Health Service operational planning guidance recommends ≥ 25% of consultations are delivered remotely. There is a lack of data regarding the acceptability and effectiveness of paediatric dermatology teleconsultations.

Provenancing 16th and 17th century CE building timbers in Denmark-combining dendroprovenance and Sr isotopic analysis.

Dendrochronology (tree-ring analysis) allows us to precisely date and identify the origin of timber from historic contexts. However, reference datasets to determine the origin can include timber of non-local origin. Therefore, we have applied Sr isotopic on timbers from three buildings in Jutland, Denmark, mostly dating from the late 16th and early 17th centuries CE to improve and refine the provenance identification.

Batavia shipwreck timbers reveal a key to Dutch success in 17th-century world trade.

Ocean-going ships were key to rising maritime economies of the Early Modern period, and understanding how they were built is critical to grasp the challenges faced by shipwrights and merchant seafarers. Shipwreck timbers hold material evidence of the dynamic interplay of wood supplies, craftmanship, and evolving ship designs that helped shape the Early Modern world. Here we present the results of dendroarchaeological research carried out on Batavia's wreck timbers, currently on display at the Western Australian Shipwrecks Museum in Fremantle.

DNA of centuries-old timber can reveal its origin.

Oak wood was highly appreciated and widely used for construction in past centuries. As population sizes expanded in some regions of Europe, local forests were depleted of high-quality timber. Therefore, regions of soaring economies were importing timber initially from the European market and eventually from other continents.

QT dispersion, QT maximum and risk of cardiac death in the Caerphilly Heart Study.

Background: It has been postulated that increased inter-lead differences in QT interval (QT dispersion) and the maximum QT interval (QTmax), in the standard 12-lead electrocardiogram (ECG), may be associated with an increased risk of cardiac death. The aims of this study were to assess the relationship between QT dispersion and QTmax, corrected and uncorrected for heart rate, and the risk of cardiac death.

Design: Nested case-control study within the Caerphilly prospective cohort study.
