Bøker av John H. Evans

Evans, like his contemporaries, the Holtzapffels, was a manufacturer of high quality lathes; but he was also an accomplished turner and, for 33 years, the author of many articles for English Mechanic, a leading journal of the time. His broad combination of engineering and practical experience, along with his literary skills, makes Ornamental Turning one of the most useful books in the field. Clearly written and richly illustrated, with over 190 detailed line drawings and 19 plates, it provides a complete coverage of the subject. Included is information available nowhere else: a chapter on DawsonUs geometric slide rest, details on the design of many types of apparatus, and a brief chapter on electrotyping. This is a complete reprint of the original 1886 edition.

Much like past arguments about stem-cell research, the coming debate over these reproductive genetic technologies (RGTs) will be political and, for many people, religious. In order to understand how the debate will play out in the US, the author conducted a study of the claims made about RGTs by religious people from across the political spectrum.
