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.

Ever since its original publication in Germany in 1938, Max Schweidler's Die Instandetzung von Kupferstichen, Zeichnungen, Buchern usw has been recognized as a seminal modern text on the conservation and restoration of works on paper. To address what he saw as a woeful dearth of relevant literature and in order to assist those who have 'set themselves the goal of preserving cultural treasures, ' the noted German restorer composed a thorough technical manual covering a wide range of specific techniques, including detailed instructions on how to execute structural repairs and alterations that, if skilfully done, can be virtually undetectable. By the mid-twentieth century, curators and conservators of graphic arts, discovering a nearly invisible repair in an old master print or drawing, might comment that the object had been 'Schweidlerized.' This volume, based on the authoritative revised German edition of 1949, makes Schweidler's work available in English for the first time, in a meticulously edited and annotated critical edition. The editor's introduction places the work in its historical context and probes the philosophical issues the book raises, while some two hundred annotati

This book analyses the social and ethical implications of the globalization of emerging skin-whitening and anti-ageing biotechnology. Using an intersectional theoretical framework and a content analysis methodology drawn from cultural studies, the sociology of knowledge, the history of colonial medicine and critical race theory, it examines technical reports, as well as print and online advertisements from pharmaceutical and cosmetics companies for skin-whitening products. With close attention to the promises of ‘ageless beauty’, ‘brightened’, youthful skin and solutions to ‘pigmentation problems’ for non-white women, the author reveals the dynamics of racialization and biomedicalization at work. A study of a significant sector of the globalized health and wellness industries – which requires the active participation of consumers in the biomedicalization of their own bodies – Wellness in Whiteness will appeal to social scientists with interests in gender, race and ethnicity, biotechnology and embodiment.

Accelerated Aging: Photochemical and Thermal Aspects represents the culmination of more than 40 years of research by noted scientist Robert L. Feller. The book focuses on the long-term performance of materials such as wool, dyes, and organic compounds; their resistance to change when exposed to environmental factors such as oxygen, ozone, moisture, heat, and light; and their physical durability with handling and use over time. Processes of deterioration are discussed based on speeded-up laboratory studies designed to clarify the chemical reactions involved and their physical consequences.
