Before Mendel, who came closest to the truth about heredity? This book examines the activities of sheep breeders able to transform the appearance and qualities of their stock by combining different traits of body or wool into new patterns. Exploiting what were then untried procedures - individual trait selection, very close inbreeding and progeny testing - they demonstrated inheritance from both sexes and showed how it could be stabilised. Major advances in breeding are associated with the English farmer Robert Bakewell (1725-1795). By the following century, when the same procedures had been established at breeding centres in central Europe, theory as well as practice became the subject of wider attention. In the Brno Sheep Breeders' Society, discussions of patterns of heredity finally gave way to the physiological question, 'What is inherited and how?' The question was posed by Cyrill Napp, abbot of the monastery to which Mendel was admitted six years later.

Founded in a working-class neighborhood in southeast Houston in 1941, Gold Star/SugarHill Recording Studios is a major independent studio that has produced a multitude of influential hit records in an astonishingly diverse range of genres. Its roster of recorded musicians includes Lightnin' Hopkins, George Jones, Willie Nelson, Bobby "Blue" Bland, Junior Parker, Clifton Chenier, Sir Douglas Quintet, 13th Floor Elevators, Freddy Fender, Kinky Friedman, Ray Benson, Guy Clark, Lucinda Williams, BeyoncÉ and Destiny's Child, and many, many more. In House of Hits, Andy Bradley and Roger Wood chronicle the fascinating history of Gold Star/SugarHill, telling a story that effectively covers the postwar popular music industry. They describe how Houston's lack of zoning ordinances allowed founder Bill Quinn's house studio to grow into a large studio complex, just as SugarHill's willingness to transcend musical boundaries transformed it into of one of the most storied recording enterprises in America. The authors offer behind-the-scenes accounts of numerous hit recordings, spiced with anecdotes from studio insiders and musicians who recorded at SugarHill. Bradley and Wood also place significant emphasis on the role of technology in shaping the music and the evolution of the music business. They include in-depth biographies of regional stars and analysis of the various styles of music they represent, as well as a list of all of Gold Star/SugarHill's recordings that made the Billboard charts and extensive selected historical discographies of the studio's recordings.

Fit-for-purpose is a phrase familiar to all users of analytical data, who need to be assured that data provided by laboratories is both appropriate and of the required quality. Quality in the Food Analysis Laboratory surveys the procedures that a food analysis laboratory must consider to meet such requirements. The need to introduce quality assurance, the different quality models that are available and the legislative requirements are considered. Specific aspects of laboratory practice and particular areas of accreditation which may cause problems for analytical laboratories are also discussed. Covering for the first time those areas of direct importance to food analysis laboratories, this unique book will serve as an aid to those laboratories when introducing new measures and justifying those chosen.
