The problem of the arch barrel deformation in railway backfilled arch bridges caused by their typical service loads is analysed.The main attention is paid to vertical or radial displacements of characteristic points of the arch barrel.In the study results of deflection measurements carried out on single and multi-span backfilled arch bridges made o

The Devonian stem-actinoterygian Cheirolepis canadensis is potentially important to understand the evolution of the dermal skeleton of osteichthyans, but the last detailed histological study on this taxon was published more than forty years ago.Here, we present new data about the morphology and the histological structure of scales, fulcra, and fin-

Background.Coil and stent migration is a potentially catastrophic complication in endovascular neurosurgery, which may lead to cerebral thromboembolism.Techniques for removing migrated coil and stent are not well established.Methods and Results.We present three cases in which coil Bronzers or stent migration occurred during endovascular embolizatio

Nutrient-rich, turbid river plumes that are common to large lakes and coastal marine ecosystems have been hypothesized to benefit survival of fish during early life stages by increasing food availability and (or) reducing vulnerability to visual predators.However, evidence that river plumes truly benefit the recruitment process remains meager for b
