Helmholtz: A Life in Science (California Studies In The History Of Science Ser. #10)
by David CahanHermann von Helmholtz was a towering figure of nineteenth-century scientific and intellectual life. Best known for his achievements in physiology and physics, he also contributed to other disciplines such as ophthalmology, psychology, mathematics, chemical thermodynamics, and meteorology. With Helmholtz: A Life in Science, David Cahan has written a definitive biography, one that brings to light the dynamic relationship between Helmholtz’s private life, his professional pursuits, and the larger world in which he lived. ? Utilizing all of Helmholtz’s scientific and philosophical writings, as well as previously unknown letters, this book reveals the forces that drove his life—a passion to unite the sciences, vigilant attention to the sources and methods of knowledge, and a deep appreciation of the ways in which the arts and sciences could benefit each other. By placing the overall structure and development of his scientific work and philosophy within the greater context of nineteenth-century Germany, Helmholtz also serves as cultural biography of the construction of the scientific community: its laboratories, institutes, journals, disciplinary organizations, and national and international meetings. Helmholtz’s life is a shining example of what can happen when the sciences and the humanities become interwoven in the life of one highly motivated, energetic, and gifted person.

Helping Stop Hitler's Luftwaffe: The Memoirs of a Pilot Involved in the Development of Radar Interception, Vital in the Battle of Britain
by Arthur McDonaldAn RAF pilot recounts his vital role in the development of Britain’s WWII air defense system in this fascinating military memoir.During the 1930s, the UK had no realistic defense against fast-flying bomber planes. That was before radar technology proved capable of detecting an aircraft before it even reached British soil. This was shown in dramatic fashion during the Biggin Hill Experiment, when a young Arthur McDonald led three biplanes—all directed by radar sets on the ground—to intercept incoming aircraft. McDonald was told, “the whole future of this country depends on the results which you obtain.” His success led to a new military strategy focused on modern fighter planes using a newly developed radar network—all of which proved crucial during the Battle of Britain. For his work, McDonald received the Air Force Cross.In this enlightening autobiography, Air Marshal Sir Arthur McDonald describes those early radar experiments as well his other innovation, the Duxford flare path, designed to be visible to landing aircraft but not to enemy attackers. McDonald went on to hold many senior posts in the RAF before retiring in 1962. But it his part in the development of Britain’s air defense at the most crucial time in its history for which he will always be remembered.
Hemeon's Plant & Process Ventilation
by D. Jeff BurtonIndustrial hygienists and ventilation engineers know the name well: W.C.L. Hemeon. Since 1955, those professionals have frequently looked to Hemeon's Plant & Process Ventilation for essential information on industrial ventilation. Hemeon's longtime influence and inspiration has now prompted D. Jeff Burton-a prolific author on industrial ventilation himself-to produce a Fourth Edition of "the classic industrial ventilation text."While retaining Hemeon's distinctive writing style, conveying practical information in vivid phrasing, Burton has added extensive new information to recognize today's technology and techniques.Essential fundamentals of ventilation covered in the book include an explanation about the dynamic properties of airborne contaminants, and the principles of dispersion mechanism and local exhaust. Advanced applications are also examined in detail, particularly system design, dust control, and troubleshooting.Along with providing essential background on the two primary types of workplace ventilation-general and local exhaust-Hemeon's Plant & Process Ventilation also aims for mutual understanding between the health-oriented priorities of industrial hygienists, and the practical applications for maximum efficiency considered by ventilation engineers.Have a well-thumbed, dog-eared copy of Hemeon's Plant & Process Ventilation? Now is the best time to retire it in favor of this revised-and respectful-edition. Those who are new to Hemeon's approach will discover what other professionals have known more than 40 years: Hemeon offers some of the most effective ways to control environmental contaminates through proper ventilation techniques.

Hemp and Sustainability (Sustainable Textiles: Production, Processing, Manufacturing & Chemistry)
by Fieke Dhondt Subramanian Senthilkannan MuthuThis book highlights the positive and negative impacts that hemp fibre and textiles have on environment, while studying the effects of climate change on the growth of fibre hemp. Human-induced climate change challenge the availability of textile fibres, whereas today’s apparel industry leaves behind a substantial environmental footprint. Sustainable hemp textiles can lighten it. The book describes the environmental impact of hemp and how climate change influences future hemp growth. Hemp is considered in most literature as a sustainable alternative for the commonly used fibres polyester and cotton. However, most research does not go farther than the environmental impacts of hemp, and there is currently a lack of knowledge/literature that examines the possibilities of hemp growth under changing climate conditions.
Hemp Bound: Dispatches from the Front Lines of the Next Agricultural Revolution
by null Doug Fine"Doug has created a blueprint for the America of the future.&”—Willie NelsonThe stat sheet on hemp sounds almost too good to be true: its fibers are among the planet&’s strongest, its seed oil the most nutritious, and its potential as an energy source vast and untapped. Its one downside? For nearly a century, it&’s been illegal to grow industrial cannabis in the United States–even though Betsy Ross wove the nation&’s first flag out of hemp fabric, Thomas Jefferson composed the Declaration of Independence on it, and colonists could pay their taxes with it. But as the prohibition on hemp&’s psychoactive cousin winds down, one of humanity&’s longest-utilized plants is about to be reincorporated into the American economy. Get ready for the newest billion-dollar industry.In Hemp Bound: Dispatches from the Front Lines of the Next Agricultural Revolution, bestselling author Doug Fine embarks on a humorous yet rigorous journey to meet the men and women who are testing, researching, and pioneering hemp&’s applications for the twenty-first century. From Denver, where Fine hitches a ride in a hemp-powered limo; to Asheville, North Carolina, where carbon-negative hempcrete-insulated houses are sparking a mini housing boom; to Manitoba where he raps his knuckles on the hood of a hemp tractor; and finally to the fields of east Colorado, where practical farmers are looking toward hemp to restore their agricultural economy—Fine learns how eminently possible it is for this misunderstood plant to help us end dependence on fossil fuels, heal farm soils damaged after a century of growing monocultures, and bring even more taxable revenue into the economy than its smokable relative.Fine&’s journey will not only leave you wondering why we ever stopped cultivating this miracle crop, it will fire you up to sow a field of it for yourself, for the nation&’s economy, and for the planet.
