Book Description
Green Sands is Kirk's chronicle of her life in the desert, told with exceptional candor and detail. Local Bedouins, foreign farm workers and their families, Saudi royalty, assorted Westerners, and fellow Americans share their desert world with Kirk. Her sincere curiosity, empathy, and warmth toward these new friends make her story entertaining as well as enlightening. There is a freshness to Kirk's perspective that puts the reader squarely in her shoes as she struggles to assimilate a culture so alien to her own and to embrace an adventure that few have the chance to experience. Martha Kirk shows her pioneering Texas spirit in the pages of Green Sands as she gamely kills camel spiders in the house, bravely risks imprisonment while driving the farm's pickup truck, and lovingly shares meals with Bedouin women and their children.

Book Description
The metal casting, uses large amounts of natural resources, energy and metals as well as generates significant amounts of gases and solid wastes, which have an essential influence on the natural environment and work conditions in casting houses. The condition of the further development is the adjustment to the strategy of the sustainable development.This book examines potential solutions to the economic, ecological, and occupational hazards generated by the foundry industry. It focuses on emissions of chemical compounds during the preparation and formation of molding sands, molds pouring with molten metal, molds cooling and castings knocking out. It also addresses the effects of the spent molding sands reclamation process and the influence of spent sands on the environment during their storage. Establishing the most sustainable techniques for limiting the negative impact of foundry processes on the environment is explored in detail. The book will be valuable to academics and industry professionals alike. Describes the mechanisms of hardening and thermal destruction of individual binders in moulding and core sands; Assesses the influence of moulding and core sands technology on the environment; Discusses state of the art moulding and core sand technology.

Book Description
The first edition appeared fourteen years ago. Since then there have been significant advances in our science that warrant an updating and revision of Sand and Sandstone. The main framework of the first edition has been retained so that the reader can begin with the mineralogy and textural properties of sands and sandstones, progress through their organization and classification and their study as a body of rock, to consideration of their origin-prove nance, transportation, deposition, and lithification-and finally to their place in the stratigraphic column and the basin. The last decade has seen the rise of facies analysis based on a closer look at the stratigraphic record and the recognition of characteristic bed ding sequences that are the signatures of some geologic process-such as a prograding shallow-water delta or the migration of a point bar on an alluvial floodplain. The environment of sand deposition is more closely determined by its place in such depositional systems than by criteria based on textural characteristics-the "fingerprint" approach. Our revi sion reflects this change in thinking. As in the geological sciences as a whole, the concept of plate tectonics has required a rethinking of our older ideas about the origin and accumu lation of sediments-especially the nature of the sedimentary basins.
