Pressure vessels are closed containers designed to hold gases or liquids at a pressure substantially different from the ambient pressure. They have a variety of applications in industry, including in oil refineries, nuclear reactors, vehicle airbrake reservoirs, and more. The pressure differential with such vessels is dangerous, and due to the risk of accident and fatality around their use, the design, manufacture, operation and inspection of pressure vessels is regulated by engineering authorities and guided by legal codes and standards. Pressure Vessel Design Manual is a solutions-focused guide to the many problems and technical challenges involved in the design of pressure vessels to match stringent standards and codes. It brings together otherwise scattered information and explanations into one easy-to-use resource to minimize research and take readers from problem to solution in the most direct manner possible. - Covers almost all problems that a working pressure vessel designer can expect to face, with 50+ step-by-step design procedures including a wealth of equations, explanations and data - Internationally recognized, widely referenced and trusted, with 20+ years of use in over 30 countries making it an accepted industry standard guide - Now revised with up-to-date ASME, ASCE and API regulatory code information, and dual unit coverage for increased ease of international use
Out of over 40 years of experience in adult or worker education, David Greene brings us tools to develop consciousness and leadership for social change. Based on the power of our huge working class to understand this economic system and to organize, this book aims to empower educators, students and other workers with science applied to solving the serious social problems we face today. We are confronted with the issues of low-wage, part-time and temporary jobs, inadequate housing, health care, and transportation, inequality and injustice, at the same time as the greatest concentration of wealth in human history. The disparity of wealth and control has never been greater. The only way out of this deepening crisis is through education. To change this we need understanding that is based on the clearest reflection of the real world. Unfit to Be a Slave employs the tools of theory and informed practice, to guide us to create spaces to share experience, study history’s lessons and develop consciousness. As a collective and organized force we can transform our communities, our countries and our world. Mythologies that tell people, ‘Things don’t change,’ ‘We can’t do anything,’ or ‘It has always been this way,’ prevent poor and working class populations from taking necessary action on behalf of their own lives and families. Unfit to Be a Slave is meant to be a guide to education for social change.
This collection of 23 essays, presented in three sections, aims to discuss women’s studies as well as methodological and theoretical approaches to gender within the broad framework of ancient Near Eastern studies. The first section, comprising most of the contributions, is devoted to Assyriology and ancient Near Eastern archaeology. The second and third sections are devoted to Egyptology and to ancient Israel and biblical studies respectively, neighbouring fields of research included in the volume to enrich the debate and facilitate academic exchange. Altogether these essays offer a variety of sources and perspectives, from the textual to the archaeological, from bodies and sexuality to onomastics, to name just a few, making this a useful resource for all those interested in the study of women and gender in the past.
This first of three volumes starts with a short introduction to historical metrology as a scientific discipline and goes on with an anthology of acient and modern measurement systems of all kind, scientific measures, units of time, weights, currencies etc. It concludes with an exhaustive list of references. Units of measurement are of vital importance in every civilization through history. Since the early ages, man has through necessity devised various measures to assist him in everyday life. They have enabled and continue to enable us to trade in commonly and equitably understood amounts, and to investigate, understand, and control the chemical, physical, and biological processes of the natural world. The essence of the work is an alphabetically ordered, comprehensive list of measurement nomenclature, units and scales. It provides an understanding of almost all quantitative expressions observed in all imaginable situations, including spelling variants and the abbreviations and symbols for units, and various acronyms used in metrology. It will be of use not only to historians of science and technology, but also to economic and social historians and should be in every major academic and national library as standard reference work on the topic.
