Taschenbuch. Zustand: 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 understanding 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.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - During the last few years, the number of contributions to the Paleontology of Mexico has increased considerably. Paleontological work in Mexico has been focused on providing important information for petroleum exploration and specific studies dealing with pollen, foraminifera, radiolaria, dinoflagellates, rudists, and ammonites. Often these reports were published only in local or regional journals and therefore not available to the scientific community at large. The purpose of this book is to offer an updated review of the fossil groups from Mexico, providing their significance to the stratigraphy, tectonics, sedimentology, evolution and paleontology of Mexico whose study has proved to be relevant in stratigraphy, tectonics, sedimentology, and evolution. The fossil record of Mexico ranges from Precambrian to Pleistocene. Almost every Mexican State has reported fossil localities with ongoing studies and potential for the discovery of new localities. Even those localities that have been studied since the eighteen-century, such as the early Cretaceous San Juan Raya, have recently reported new fossil groups. Unfortunately, much of the fossil reports from Mexico have been published in Spanish from local journals, which represent a language barrier to the international community. There is little doubt that the paleontological history of Mexico deserves to be known in other countries. By making this book available to the international scientific community we hope that interest in the fossil record of Mexico will grow.…
