Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book provides an excellent illustration of the interrelationship between progress in scientific methodology and conceptual advances, and its publica tion should contribute to further advances. It is well known that major advances in understand…ing often follow the development of new methods. The development of the acetylene reduction assay for nitrogenase activity provides a good example of this interrelationship between theory and methods. Theoretical knowledge led to a search for substrates for nitro genase that could be assayed for more easily than ammonium, the normal product of the enzyme. The discovery of the reduction of acetylene to ethylene by nitrogenase provided the ideal answer to the problem by provid ing a rapid, specific, nondestructive, and inexpensive assay for nitrogenase activity. This assay is now used by almost every laboratory doing research on nitrogen fixation. However, further use and development of the acetylene reduction assay has shown that it can underestimate nitrogenase activity and can even give incorrect relative values under some circumstances. The major problem is that exposure of legume nodules to acetylene can cause a large increase in the resistance to oxygen diffusion into the nodule. This reduced supply of oxygen decreases the rate of nitrogenase activity within a few minutes.

Hardcover. Condición: Good. First edition. John Wesley Powell's copy of Volume II of these 1853-54 reports, with his stamp faintly in purple ink on the title page. A good only copy with dampstaining throughout, but collectible in light of its owner, who famously would go on to survey and provide his own report on the Grand Canyo…n. These 1853-54 reports were issued somewhat haphazardly in 12 volumes, apparently as they were received rather than by region. Volume II contains the following: 1) "Report, by Lieutenant E.G. Beckwith, Third Artillery, upon the Route near the Thirty-Eighth and Thirty-Ninth Parallels Explored by Captain J.W. Gunnison, Corps of Topographical Engineers" (Gunnison was killed on the journey); 2) "Report of Lieutenant E.G. Beckwith . . . upon the Route near the Forty-First Parallel"; 3) Report of a Reconnaissance from Puget Sound, via South Pass, to the Mississippi River, by F.W. Lander, Civil Engineer"; 4) "Report of Brevet Captain John Pope, Corps Topographical Engineers, upon the Portion of the Route near the Thirty-Second Parallel, Lying between the Red River [the Colorado] and the Rio Grande"; 5) "Report of Lieutenant John G. Park, Corps Topographical Engineers, upon the Portion of the Route near the Thirty-Second Parallel, Lying between the Rio Grande and Pimas Village, on the Gila"; and 6) "Extract from Report of a Military Reconnaissance Made by Lieutenant Colonel W.H. Emory, U.S. Army, of the Portion of the Route near the Thirty-Second Parallel, Lying between the Mouths of the San Pedro and Gila Rivers." Among several of the later reports are botanical sections by Asa Gray and John Torrey. These are replete with nice line-drawing botanical plates. In the first Beckwith report, J.M. Stanley provides a series of beautiful vista illustrations in color of the Gunnison route. Near the rear are a fold out map and a fold out geological section depicting the stretch between the Colorado River ("Red River) and the Rio Grande. A contemporary binding of red cloth and quarter/corner leather, with five raised bands and gilt lettering on spine. Red marbled endpapers. Again, good only with dampstaining to all corners of the pages, top and bottom (see photos). The pages have some light waviness to them, but turn fine and are readable, the text itself mostly free of staining. Mottling on front board, wrinkle on rear. Rubbing to board edges and nicks to spine corners as one might expect for a heavy book of this age. Despite its condition, still a special copy--Powell's.The inclusion of the Colorado River in the fourth report in the volume would have ultimately been of special interest to him, and one imagines the example of these reports would have influenced his own.
