Analytical studies of the degradation of cellulose nitrate plastics in museums
This paper discusses a project which is examining the degradation of cellulose nitrate artefacts. Several analytical techniques including Fourier transform infrared (FTIR) spectroscopy and ion chromatography have been used to investigate the degradation processes occurring and the various factors influencing the rate of degradation. Accelerated ageing of cellulose nitrate has...Stewart, R ; Littlejohn, D ; Pethrick, R P ; Quye, Anita ; Tennent, N H

Genetic variation in field voles (Microtus agrestis) from the British Isles: selective sweeps or population bottlenecks?
The Eurasian field vole (Microtus agrestis) comprises three evolutionarily significant units (ESUs). The northern ESU is found at higher latitudes across the western Palaearctic region and includes six, largely allopatric, mitochondrial DNA lineages that were derived from population bottlenecks. One of these lineages is found in southern Britain and nearby...Herman, Jeremy S ; Stojack, Joanna ; Paupério, Joana ; Jaarola, M ; Wojcik, J M …

Silver dirhams from the Storr Rock Viking Hoard
A 10th-century hoard found on the Isle of Skye contained 19 dirhams, silver coins from the Islamic emirates of central Asia. These were not exotic curiosities collected by a Viking traveller, but evidence of trade routes connecting Scotland across vast distances at the turn of the first millennium.Maldonado, Adrián
