Hot-dip galvanization is a method for coating steel workpieces with a protective zinc film to enhance the corrosion resistance and to improve the mechanical material properties. Hot-dip galvanized steel is the material of choice underlying many modern buildings and constructions, such as train stations, bridges and metal domes. Based on the successful German version, this edition has been adapted to include international standards, regulations and best practices. The book systematically covers all steps in hot-dip galvanization: surface pre-treatment, process and systems technology, environmental issues, and quality management. As a result, the reader finds the fundamentals as well as the most important aspects of process technology and technical equipment, alongside contributions on workpiece requirements for optimal galvanization results and methods for applying additional protective coatings to the galvanized pieces. With over 200 illustrated examples, step-by-step instructions, presentations and reference tables, this is essential reading for apprentices and professionals alike.
Humankind's use of zinc stretches back to antiquity, and it was a component in some of the earliest known alloy systems. Even though metallic zinc was not "discovered" in Europe until 1746 (by Marggral), zinc ores were used for making brass in biblical times, and an 87% zinc alloy was found in prehistoric ruins in Transylvania. Also, zinc (the metal) was produced in quantity in India as far back as the thirteenth century, well before it was recognized as being a separate element. The uses of zinc are manifold, ranging from galvanizing to die castings to electronics. It is a preferred anode material in high-energy-density batteries (e.g., Ni/Zn, Ag/Zn, ZnJair), so that its electrochemistry, particularly in alkaline media, has been extensively explored. In the passive state, zinc is photoelectrochemically active, with the passive film displaying n-type characteristics. For the same reason that zinc is considered to be an excellent battery anode, it has found extensive use as a sacrificial anode for the protection of ships and pipelines from corrosion. Indeed, aside from zinc's well-known attributes as an alloying element, its widespread use is principally due to its electrochemical properties, which include a well-placed position in the galvanic series for protecting iron and steel in natural aqueous environments and its reversible dissolution behavior in alkaline solutions.
Thinkers50 Top 10 Best New Management Books for 2022 A distinguished Harvard Business School professor offers a compelling reassessment and defense of purpose as a management ethos, documenting the vast performance gains and social benefits that become possible when firms manage to get purpose right. Few business topics have aroused more skepticism in recent years than the notion of corporate purpose, and for good reason. Too many companies deploy purpose, or a reason for being, as a promotional vehicle to make themselves feel virtuous and to look good to the outside world. Some have only foggy ideas about what purpose is and conflate it with strategy and other concepts like “mission,” “vision,” and “values.” Even well-intentioned leaders don’t understand purpose’s full potential and engage half-heartedly and superficially with it. Outsiders spot this and become cynical about companies and the broader capitalist endeavor. Having conducted extensive field research, Ranjay Gulati reveals the fatal mistakes leaders unwittingly make when attempting to implement a reason for being. Moreover, he shows how companies can embed purpose much more deeply than they currently do, delivering impressive performance benefits that reward customers, suppliers, employees, shareholders, and communities alike. To get purpose right, leaders must fundamentally change not only how they execute it but also how they conceive of and relate to it. They must practice what Gulati calls deep purpose, furthering each organization’s reason for being more intensely, thoughtfully, and comprehensively than ever before. In this authoritative, accessible, and inspiring guide, Gulati takes readers inside some of the world’s most purposeful companies to understand the secrets to their successes. He explores how leaders can pursue purpose more deeply by navigating the inevitable tradeoffs more deliberately and effectively to balance between short- and long-term value; building purpose more systematically into every key organizational function to mobilize stakeholders and enhance performance; updating organizations to foster more autonomy and collaboration, which in turn allow individual employees to work more purposefully; using powerful storytelling to communicate a reason for being, arousing emotions and building a community of inspired and committed stakeholders; and building cultures that don’t merely support purpose, but also allow employees to link the corporate purpose to their own personal reasons for being. As Gulati argues, a deeper engagement with purpose holds the key not merely to the well-being of individual companies but also to humanity’s future. With capitalism under siege and relatively low levels of trust in business, purpose can serve as a radically new operating system for the enterprise, enhancing performance while also delivering meaningful benefits to society. It’s the kind of inspired thinking that businesses—and the rest of us—urgently need.
From the Wall Street Journal's opera critic, a wide-ranging narrative history of how and why the New York City Opera went bankrupt—and what it means for the future of the arts In October 2013, the arts world was rocked by the news that the New York City Opera—“the people’s opera”—had finally succumbed to financial hardship after 70 years in operation. The company had been a fixture on the national opera scene—as the populist antithesis of the grand Metropolitan Opera, a nurturing home for young American talent, and a place where new, lively ideas shook up a venerable art form. But NYCO’s demise represented more than the loss of a cherished organization: it was a harbinger of massive upheaval in the performing arts—and a warning about how cultural institutions would need to change in order to survive. Drawing on extensive research and reporting, Heidi Waleson, one of the foremost American opera critics, recounts the history of this scrappy company and reveals how, from the beginning, it precariously balanced an ambitious artistic program on fragile financial supports. Waleson also looks forward and considers some better-managed, more visionary opera companies that have taken City Opera’s lessons to heart. Above all, Mad Scenes and Exit Arias is a story of money, ego, changes in institutional identity, competing forces of populism and elitism, and the ongoing debate about the role of the arts in society. It serves as a detailed case study not only for an American arts organization, but also for the sustainability and management of nonprofit organizations across the country.
