The rapid progress on somatic embryogenesis and its prospects for potential application to improving woody plants prompted us to edit this book initially in three volumes, and now an additional three more volumes. We were all convinced that such a treatise was needed and would be extremely useful to researchers and students. This volume 6 is dedicated to Prof. Harry Waris, Helsinki, Finland, who did pioneer work on somatic embryogenesis during the time when Prof. Steward and others were actively engaged in this area. His former student Prof. Liisa Simols, University of Helsinki, Finland, has written a dedication `Harry Waris, a pioneer in somatic embryogenesis' to her teacher Prof. Waris. Th...
Written primarily for researchers and graduate students who are new in this emerging field, this book develops the necessary tools so that readers can follow the latest advances in this subject. Readers are first guided to examine the basic informations on nucleon-nucleon collisions and the use of the nucleus as an arena to study the interaction of one nucleon with another. A good survey of the relation between nucleon-nucleon and nucleus-nucleus collisions provides the proper comparison to study phenomena involving the more exotic quark-gluon plasma. Properties of the quark-gluon plasma and signatures for its detection are discussed to aid future searches and exploration for this exotic matter. Recent experimental findings are summarised.
This book provides the reader with a detailed and captivating account of the story where, for the first time, physicists ventured into proposing a new force of nature beyond the four known ones - the electromagnetic, weak and strong forces, and gravitation - based entirely on the reanalysis of existing experimental data. Back in 1986, Ephraim Fischbach, Sam Aronson, Carrick Talmadge and their collaborators proposed a modification of Newton’s Law of universal gravitation. Underlying this proposal were three tantalizing pieces of evidence: 1) an energy dependence of the CP (particle-antiparticle and reflection symmetry) parameters, 2) differences between the measurements of G, the universal ...
! Morphogenesis, or developmental morphology, is a dynamic process! and a fascinating field of investigation. Since the beginning of this century plant morphologists (Eames, 1961), anatomists (Eames and Macdaniels, 1947) and embryologists (Maheshwari, 1950) have studied the processes of development and differentiation by observing whole plants and their histological preparations and have generated a wealth of information on the structural changes associated with various developmental stages in the life cycle of a large number of plant species. Around 1940 plant morphogenesis became an experimental field when plant physiologists initiated studies on the effect of treatments, such as application of physiologically active compounds or growth regulators, irradiation, exposure to different day length, temperature and injury, on morphological and structural changes. During the past two decades geneticists and molecular biologists have become interested in plant morphogenesis and extensive work is being done to understand the regulation of gene expression during morphogenesis and how the products of genetic information control the developmental processess.
