The central issues discussed in this new collected work in the highly successful ancient textiles series are the relationships between fiber resources and availability on the one hand and the ways those resources were exploited to produce textiles on the other. Technological and economic practices - for example, the strategies by which raw materials were acquired and prepared - in the production of textiles play a major role in the papers collected here. Contributions investigate the beginnings of wool use in western Asia and southeastern Europe. The importance of wool in considerations of early textiles is due to at least two factors. First, both wild as well as some domesticated sheep are characterized by a hairy rather than a woolly coat. This raises the question of when and where woolly sheep emerged, a question that has not up to now been resolvable by genetic or other biological analyses. Second, wool as a fiber has played a major role both economically and socially in both western Asian and European societies from as early as the 3rd millennium BCE in Mesopotamia, and it continues to do so, in different ways, up to the modern day. Despite the importance of wool as a fiber resource contributors demonstrate clearly that its development and use can only be properly addressed in the context of a consideration of other fibers, both plant and animal. Only within a framework that takes into account historically and regionally variable strategies of procurement, processing, and the products of different types of fibers is it possible to gain real insights into the changing roles played by fibers and textiles in the lives of people in different places and times in the past. With relatively rare, albeit sometimes spectacular exceptions, archaeological contexts offer only poor conditions of preservation for textiles. As a result, archaeologists are dependent on indirect or proxy indicators such as textile tools (e.g., loom weights, spindle whorls) and the analysis of faunal remains to explore a range of such proxies and methods by which they may be analyzed and evaluated in order to contribute to an understanding of fiber and textile production and use in the past.

The Handbook of Natural Fibres, Second Edition, Volume One: Types, Properties and Factors Affecting Breeding and Cultivation covers every aspect of natural fibers, their breeding, cultivation, processing and applications. This volume features fundamental discussions of each fiber, covering different stages of breeding and cultivation. Natural fibrous resources, both lignocellulosic and protein ones, are renewable, biodegradable, and nontoxic, making them an important source of sustainable textile solutions. A broad range of natural fibers are covered in this book, including cotton, jute, kenaf, flax, hemp, sisal, ramie, curaua, pineapple, bamboo, coir, sheep wool, and more. - Provides detailed instructions for how to carry out the latest scientific methods for identifying natural fibers - Explains properties of natural fibers that will be of interest to readers in growth fields like biocomposites and nanofibers - Includes a rare overview of emerging natural fibers and their uses, along with sources of further information

This thoroughly researched book analyses the role of industrial research in DSM's transformations.

Multi-scale modelling of composites is a very relevant topic in composites science. This is illustrated by the numerous sessions in the recent European and International Conferences on Composite Materials, but also by the fast developments in multi-scale modelling software tools, developed by large industrial players such as Siemens (Virtual Material Characterization toolkit and MultiMechanics virtual testing software), MSC/e-Xstream (Digimat software), Simulia (micromechanics plug-in in Abaqus), HyperSizer (Multi-scale design of composites), Altair (Altair Multiscale Designer) This book is intended to be an ideal reference on the latest advances in multi-scale modelling of fibre-reinforced polymer composites, that is accessible for both (young) researchers and end users of modelling software. We target three main groups: This book aims at a complete introduction and overview of the state-of-the-art in multi-scale modelling of composites in three axes: • ranging from prediction of homogenized elastic properties to nonlinear material behaviour • ranging from geometrical models for random packing of unidirectional fibres over meso-scale geometries for textile composites to orientation tensors for short fibre composites • ranging from damage modelling of unidirectionally reinforced composites over textile composites to short fibre-reinforced composites The book covers the three most important scales in multi-scale modelling of composites: (i) micro-scale, (ii) meso-scale and (iii) macro-scale. The nano-scale and related atomistic and molecular modelling approaches are deliberately excluded, since the book wants to focus on continuum mechanics and there are already a lot of dedicated books about polymer nanocomposites. A strong focus is put on physics-based damage modelling, in the sense that the chapters devote attention to modelling the different damage mechanisms (matrix cracking, fibre/matrix debonding, delamination, fibre fracture,...) in such a way that the underlying physics of the initiation and growth of these damage modes is respected. The book also gives room to not only discuss the finite element based approaches for multi-scale modelling, but also much faster methods that are popular in industrial software, such as Mean Field Homogenization methods (based on Mori-Tanaka and Eshelby solutions) and variational methods (shear lag theory and more advanced theories). Since the book targets a wide audience, the focus is put on the most common numerical approaches that are used in multi-scale modelling. Very specialized numerical methods like peridynamics modelling, Material Point Method, eXtended Finite Element Method (XFEM), isogeometric analysis, SPH (Smoothed Particle Hydrodynamics),... are excluded. Outline of the book The book is divided in three large parts, well balanced with each a similar number of chapters:

The motion and deformation of rocks are processes of fundamental importance in shaping the Earth, from outer crustal layers to the deep mantle. Reconstructions of the evolution of the Earth therefore require detailed knowledge of the geometry of deformation structures and their relative timing, of the motions leading to deformation structures and of the mechanisms governing these motions. This volume contains a collection of 22 papers on field, experimental and theoretical studies that add to our knowledge of these processes.
