Work-Life Advantage analyses how employer-provision of ‘family-friendly’ working arrangements – designed to help workers better reconcile work, home and family – can also enhance firms’ capacities for learning and innovation, in pursuit of long-term competitive advantage and socially inclusive growth. Brings together major debates in labour geography, feminist geography, and regional learning in novel ways, through a focus on the shifting boundaries between work, home, and family Addresses a major gap in the scholarly research surrounding the narrow ‘business case’ for work-life balance by developing a more socially progressive, workerist ‘dual agenda’ Challenges and disrupts masculinist assumptions of the “ideal worker” and the associated labour market marginalization of workers with significant home and family commitments Based on 10 years of research with over 300 IT workers and 150 IT firms in the UK and Ireland, with important insights for professional workers and knowledge-intensive companies around the world

The third edition of this long-selling introductory textbook and ready reference covers all pertinent topics, from basic statistics via modeling and databases right up to the latest regulatory issues. The experienced and internationally recognized author, Matthias Otto, introduces the statistical-mathematical evaluation of chemical measurements, especially analytical ones, going on to provide a modern approach to signal processing, designing and optimizing experiments, pattern recognition and classification, as well as modeling simple and nonlinear relationships. Analytical databases are equally covered as are applications of multiway analysis, artificial intelligence, fuzzy theory, neural networks, and genetic algorithms. The new edition has 10% new content to cover such recent developments as orthogonal signal correction and new data exchange formats, tree based classification and regression, independent component analysis, ensemble methods and neuro-fuzzy systems. It still retains, however, the proven features from previous editions: worked examples, questions and problems, additional information and brief explanations in the margin.

Was passiert beim Erhitzen eines kohlensäurehaltigen Mineralwassers? Wie viel Ascorbinsäure (= Vitamin C) ist im Apfel? Wie verändert sich der pH-Wert beim Lösen von Brausetabletten? Was passiert während der Gärung? Stets spielen chemische Gleichgewichte (und deren Verschiebungen, u.a. durch pH-Änderungen), Oxidationen und Reduktionen eine Rolle. Als wichtiges Hilfsmittel für die insgesamt 131 Experimente werden Teststäbchen verwendet, die in kürzester Zeit halb-quantitative Analysen ermöglichen. Auf diese Weise lassen sich auch Reaktionsverläufe erfassen – ebenso wie Lösungs- und Fällungsreaktionen. Das Verstehen-Lernen chemischer Reaktionen steht im Vordergrund aller Experimente. Dem Kapitel Gleichgewichtsreaktionen folgen Redox-Reaktionen am Beispiel von Kupfer, Eisen, Ascorbinsäure, Sulfit/Sulfat und Nitrit/Nitrat. Den chemischen und enzymatischen Reaktionen von Glucose ist ein weiteres Kapitel gewidmet. Gleichzeitig wird die chemische Fachsprache erläutert und geübt. Ein Muss für jedes Schülerlabor, engagierte Lehrer und jeden an Chemie Interessierten: das Buch hilft beim Erlernen und der Verinnerlichung der chemischen Denkweise.
An affordable, easily accessible desk reference on biomanufacturing, focused on downstream recovery and purification Advances in the fundamental knowledge surrounding biotechnology, novel materials, and advanced engineering approaches continue to be translated into bioprocesses that bring new products to market at a significantly faster pace than most other industries. Industrial scale biotechnology and new manufacturing methods are revolutionizing medicine, environmental monitoring and remediation, consumer products, food production, agriculture, and forestry, and continue to be a major area of research. The downstream stage in industrial biotechnology refers to recovery, isolation, and purification of the microbial products from cell debris, processing medium and contaminating biomolecules from the upstream process into a finished product such as biopharmaceuticals and vaccines. Downstream process design has the greatest impact on overall biomanufacturing cost because not only does the biochemistry of different products ( e.g., peptides, proteins, hormones, antibiotics, and complex antigens) dictate different methods for the isolation and purification of these products, but contaminating byproducts can also reduce overall process yield, and may have serious consequences on clinical safety and efficacy. Therefore downstream separation scientists and engineers are continually seeking to eliminate, or combine, unit operations to minimize the number of process steps in order to maximize product recovery at a specified concentration and purity. Based on Wiley's Encyclopedia of Industrial Biotechnology: Bioprocess, Bioseparation, and Cell Technology, this volume features fifty articles that provide information on down- stream recovery of cells and protein capture; process development and facility design; equipment; PAT in downstream processes; downstream cGMP operations; and regulatory compliance. It covers: Cell wall disruption and lysis Cell recovery by centrifugation and filtration Large-scale protein chromatography Scale down of biopharmaceutical purification operations Lipopolysaccharide removal Porous media in biotechnology Equipment used in industrial protein purification Affinity chromatography Antibody purification, monoclonal and polyclonal Protein aggregation, precipitation and crystallization Freeze-drying of biopharmaceuticals Biopharmaceutical facility design and validation Pharmaceutical bioburden testing Regulatory requirements Ideal for graduate and advanced undergraduate courses on biomanufacturing, biochemical engineering, biophar- maceutical facility design, biochemistry, industrial microbiology, gene expression technology, and cell culture technology, Downstream Industrial Biotechnology is also a highly recommended resource for industry professionals and libraries.
