Download or read book Pulp Bleaching Today written by Hans Ulrich Suess and published by Walter de Gruyter. This book was released on 2010-04-23 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the most effective application of chemicals in bleaching. It starts with a brief overview of the history of bleaching and then focuses on recent developments. The ban of chlorine from bleaching pulp has shifted bleaching to environmentally sound procedures. Elementary Chlorine Free bleaching (ECF bleaching) and Totally Chlorine Free bleaching (TCF bleaching) are explained. The potential of different bleaching chemicals is exemplified in detail with a special focus on what to do and what to avoid. Very recent knowledge about the sources of yellowing is utilized to explain the ideal strategy for the removal of chromophores and their precursors. Emphasis is placed on applicable bleaching, in clear contrast to sophisticated, complicated or simply expensive pseudo modern bleaching. The target of this book is to explain the potential and the limitations of different chemicals and to demonstrate the necessity of comprehensive solutions for an environmentally sound use of the raw material wood, of chemicals, and of water in the production of pulp with top quality and yield. This book should educate students in the art of bleaching, assist mill personal in their continuous effort for process optimization, help research and technology managers to successfully select their targets, and be on hand as reference of the most recent bleaching technology.

Download or read book Environmentally Benign Approaches for Pulp Bleaching written by Pratima Bajpai and published by Elsevier. This book was released on 2012-05-30 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pulp and paper production has increased globally and will continue to increase in the near future. Approximately 155 million tons of wood pulp is produced worldwide and about 260 million is projected for 2010. To cope with the increasing demand, an increase in production and improved environmental performance is needed as the industry is under constant pressure to reduce environmental emissions to air and water. This book gives updated information on environmentally benign approaches for pulp bleaching, which can help solve the problems associated with conventional bleaching technologies. Main focus is on the environmentally-friendly technologies that can help solve some of the problems associated with conventional bleaching technologies Information given is up-to-date, authoritative, and cites the experiences of many mills and pertinent research, which is of interest to those working in the industry or intending to do so Covers in great depth all the aspects of various bleaching processes including environmental issues

Download or read book Diversity Counts written by Anne Dymond and published by McGill-Queen's Press - MQUP. This book was released on 2019-06-30 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the common belief that art galleries will naturally become more gender equitable over time, the fact is that many art institutions in Canada have become even less so over the last decade, with female artists making up less than 25 per cent of the contemporary exhibitions of several major galleries. In the first large-scale overview of gender diversity in Canadian art exhibitions, Anne Dymond makes a persuasive plea for more consciously equitable curating. Drawing on data from nearly one hundred institutions, Diversity Counts reveals that while some galleries are relatively equitable, many continue to marginalize female and racialized artists. The book pursues an interdisciplinary approach, considering the art world's resistance to numeric data, discourses on representation and identity, changing conceptualizations of institutional responsibility over time, and different ways particular institutions manage inclusion and exclusion. A thoughtful examination of the duty of public galleries to represent underserved communities, Dymond's study bravely navigates the unspoken criteria for acceptance in the curatorial world. Demonstrating how important hard data is for inclusivity, Diversity Counts is a timely analysis that brings the art world up to date on progressive movements for social transformation.

Available in PDF, EPUB and Kindle. Book excerpt: This book explains how the performance of modern cellular wireless networks can be evaluated by measurements and simulations With the roll-out of LTE, high data throughput is promised to be available to cellular users. In case you have ever wondered how high this throughput really is, this book is the right read for you: At first, it presents results from experimental research and simulations of the physical layer of HSDPA, WiMAX, and LTE. Next, it explains in detail how measurements on such systems need to be performed in order to achieve reproducible and repeatable results. The book further addresses how wireless links can be evaluated by means of standard-compliant link-level simulation. The major challenge in this context is their complexity when investigating complete wireless cellular networks. Consequently, it is shown how system-level simulators with a higher abstraction level can be designed such that their results still match link-level simulations. Exemplarily, the book finally presents optimizations of wireless systems over several cells. This book: Explains how the performance of modern cellular wireless networks can be evaluated by measurements and simulations Discusses the concept of testbeds, highlighting the challenges and expectations when building them Explains measurement techniques, including the evaluation of the measurement quality by statistical inference techniques Presents throughput results for HSDPA, WiMAX, and LTE Demonstrates simulators at both, link- level and system-level Provides system-level and link-level simulators (for WiMAX and LTE) on an accompanying website (https://www.nt.tuwien.ac.at/downloads/featured-downloads) This book is an insightful guide for researchers and engineers working in the field of mobile radio communication as well as network planning. Advanced students studying related courses will also find the book interesting.
