With contributions from leading researchers in the field, and including recent breakthrough work, this collection of recent results on near wall turbulence includes theory, new experiments, DNS, and modeling with RANS, LES and Low Order Dynamical Systems.

This book will consist of a coherent collection of recent results on near wall turbulence including theory, new experiments, DNS, and modeling with RANS, LES and Low Order Dynamical Systems.

The aim of this Advanced Research Workshop was to bring together Physicists, Applied Mathematicians and Fluid Dynamicists, including very specially experimentalists, to review the available knowledge on the global structural aspects of turbulent flows, with an especial emphasis on open systems, and to try to reach a consensus on their possible relationship to recent advances in the understanding of the behaviour of low dimensional dynamical systems and amplitude equations. A lot has been learned during recent years on the non-equilibrium behaviour of low dimen sional dynamical systems, including some fluid flows (Rayleigh-Benard, Taylor-Couette, etc. ). These are mostly closed flows and many of the global structural features of the low dimensional systems have been observed in them, including chaotic behaviour, period doubling, intermit tency, etc. . It has also been shown that some of these flows are intrinsically low dimensional, which accounts for much of the observed similarities. Open flows seem to be different, and experimental observations point to an intrinsic high dimensionality. However, some of the tran sitional features of the low dimensional systems have been observed in them, specially in the intermittent behaviour of subcritical flows (pipes, channels, boundary layers with suction, etc. ), and in the large scale geometry of coherent structures of free shear flows (mixing layers, jets and wakes).

Nanopollutants are nanoparticles that have escaped into the environment and can include engineered nanoparticles as well as nanoparticles that are products of degradation (e.g. nanoplastics) or other processes. As many of these particles are only recently developed or described there is still a lot to learn about where they come from, where they end up and what risks they pose to health and the environment. Offering a wide overview of the most recent research on these emerging contaminants, from the investigation of their sources and fate to the analytical developments for their detection and analysis, this book gives the reader a full picture of the global research on engineered and natural nanoparticles in the environment. Taking a forward-looking perspective with chapters on new nanopollutants, regulatory direction and occurrence in different environmental compartments, this book is a great resource for anyone working in environmental chemistry, nanoscience or environmental regulation.

The Archaeology of 'Underdog Sites' in the Douro Valley brings together the best presentations from the eighth and ninth meetings of Archaeology of the Douro Valley, held in Avila and Astorga (Spain), respectively in 2018 and 2019. However, instead of a simple collection of articles, the aim of this publication is to show the importance of projects that have been left in the background despite obtaining interesting archaeological data about the occupation of this valley and its evolution. Moreover, we must take into account that many of these projects support new activity in a rural territory that is increasingly neglected politically and economically. Hence the use of the term 'underdog', defined as a person or group of people with less power or money than the rest of society. Overall, the volume provides a general and interdisciplinary view of the different types of occupation in the territory of the Douro Valley. The chapters are divided into four sections, three of them chronological: Prehistory and Protohistory; Antiquity and Late Antiquity; and the medieval and modern ages. The last section is thematic and includes diachronic studies, museology, and the archaeology of mining. Therefore, the present volume is a medium to showcase the latest research carried out in this important territory and to contribute to knowledge of its history, updating the archaeological state of the art in the valley and presenting results that may be used in the most diverse types of comparative studies.
