Download or read book City of Quartz written by Mike Davis and published by Verso Books. This book was released on 2006-09-17 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of the visionary social history of Los Angeles is “as central to the L.A. canon as anything that . . . Joan Didion wrote in the seventies” (New Yorker) No metropolis has been more loved or more hated. To its official boosters, “Los Angeles brings it all together.” To detractors, L.A. is a sunlit mortuary where “you can rot without feeling it.” To Mike Davis, the author of this fiercely elegant and wide- ranging work of social history, Los Angeles is both utopia and dystopia, a place where the last Joshua trees are being plowed under to make room for model communities in the desert, where the rich have hired their own police to fend off street gangs, as well as armed Beirut militias. In City of Quartz, Davis reconstructs L.A.’s shadow history and dissects its ethereal economy. He tells us who has the power and how they hold on to it. He gives us a city of Dickensian extremes, Pynchonesque conspiracies, and a desperation straight out of Nathaniel West—a city in which we may glimpse our own future mirrored with terrifying clarity. In this new edition, Davis provides a dazzling update on the city’s current status.

Download or read book Quartz Cementation in Sandstones written by R. Worden and published by John Wiley & Sons. This book was released on 2009-09-18 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quartz is the major porosity-reducing cement in many sandstonesequences. Therefore, Quartz cements represent a key source ofpetrographic and geochemical information about diagenetic history.They are also the major determinant of sandstone reservoirquality. While the ultimate goal of research in this area is to makerobust predictions about the amount and distribution of quartzcements in a wide variety of depositional and burial settings,there are nevertheless large areas of the subject that are poorlyunderstood and remain the subject of controversy. The aim of this Volume, which is based partly on paperssubmitted to a 1996 workshop in Belfast, and partly on invitedcontributions, is to bring together some of the main strands ofresearch into quartz cements and provide a focus for debate anddirection for future research. This book will be welcomed by sedimentologists, petrographersand geochemists involved in sandstone digenesis, as well as bypetroleum geologists seeking a deeper understanding of the factorsinfluencing reservoir porosity and permeability. Contributors from 11 countries and 4 continents. Represents the benchmark in quartz cement research.

Download or read book Recent advances in the marketing impurity characterization and purification of quartz written by Yongping Xie and published by OAE Publishing Inc.. This book was released on 2023-11-29 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its stable physical and chemical properties and its abundance in nature, quartz is widely employed in industrial and high-tech applications. However, the presence of diverse types and states of impurities in quartz ores from different geological formations poses a challenge in the process of purifying high-purity quartz, leading to wastage of raw materials and escalated costs. This study presents the socio-economic applications of quartz, scrutinizes the formation and separation mechanisms of impurities in quartz ores from a mineralogical perspective, examines the obstacles faced in quartz purification, explains the current state of development, and provides a technical summary of quartz purification. The analysis reveals that lattice impurity elements and various types of inclusion impurities are the principal factors affecting the purity of quartz. Various green separation techniques are applied based on the composition of the quartz minerals and the state of the impurities. Standard practices may involve physical pre-treatment such as scrubbing, ultrasonic crushing, and electromagnetic pulse cracking, followed by rough cleaning through color separation, superconducting high gradient magnetic separation, and flotation, and chemical pre-treatment (high-temperature or microwave roasting with chloride doping, and ammonium sulfate thermal crushing combined with water quenching to remove gas-liquid inclusions from quartz minerals). Finally, finishing processes such as fluorine-free and catalytic hot-pressure acid leaching or microbiological purification treatment with filamentous or Aspergillus fungi are used to obtain high-purity silica sand with an anticipated purity of about 99.99%.
Download or read book Understanding Quartz Crystals and Oscillators written by Ramon M. Cerda and published by Artech House. This book was released on 2014-05-01 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quartz, unique in its chemical, electrical, mechanical, and thermal properties, is used as a frequency control element in applications where stability of frequency is an absolute necessity. Without crystal controlled transmission, radio and television would not be possible in their present form. The quartz crystals allow the individual channels in communication systems to be spaced closer together to make better use of one of most precious resources -- wireless bandwidth. This book describes the characteristics of the art of crystal oscillator design, including how to specify and select crystal oscillators. While presenting various varieties of crystal oscillators, this resource also provides you with useful MathCad and Genesys simulations.
