Download or read book Comparative Embryology of Angiosperms Vol 1 2 written by Brij M. Johri and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 1243 pages. Available in PDF, EPUB and Kindle. Book excerpt: COMPARATIVE EMBRYOLOGY OF ANGIOSPERMS is a review of the developmental processes leading to sexual reproduction in flowering plants. On the basis of embryological data and certain evidences from other areas of study, it lays special emphasis on the relationship among and within the families and orders of angiosperms. Occasionally, inaccuracies in observation and interpretation are pointed out, alternative interpretations offered, gaps in our knowledge highlighted, and prospects outlined. The text is documented with 36 tables, 376 figures, and about 5000 literature citations, which contribute to making this book comprehensive. Besides students and research workers interested in angiosperm embyology, taxonomists, plant breeders, agriculturists, and horticulturists will also find much useful information in this treatise.

This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the Serono Symposium on Pre implantation Embryo Development, held in Newton, Massachusetts, in 1991. The idea for the symposium grew out of the 1989 Serono Symposium on Fertilization in Mammals* at which preimplantation development was the predominant suggestion for a follow-up topic. This was indeed a timely subject in view of the recent resurgence of interest in this funda mental phase of embryogenesis and its relevance to basic research and applied fertility studies in humans, food-producing animals, and endangered species. The symposium brought together speakers from a broad range of disciplines in order to focus on key regulatory mechanisms in embryo development, using a wide variety of animal models, and on representative topics in human preimplantation embryogenesis. The culmination of preimplantation development is a blastocyst con taining the first differentiated embryonic tissues and capable of initiating and sustaining pregnancy. The central objective of the symposium was to throw light on the regulation of cellular and molecular events underlying blastocyst formation. It was particularly appropriate that the date of the symposium marked the 20th anniversary of the publication of the classic volume Biology of the Blastocyst, the proceedings of an international workshop held in 1970. This book, which summarized most of the information then available on this topic in mammals, was edited by the pioneer in blastocyst research, Dr. Richard B1andau, who was the guest speaker at the symposium.

Download or read book Herpetological Osteopathology written by Bruce M. Rothschild and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.

Download or read book In Vitro Embryogenesis in Plants written by Trevor A. Thorpe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: In vitro Embryogenesis in Plants is the first book devoted exclusively to this topic. As the ultimate demonstration of totipotency in plants, somatic and haploid embryogenesis is of vital importance to all those working on or interested in basic and applied aspects of plantlet information and regeneration. The text includes comprehensive reviews written by experts, on all facts of in vitro and in vivo embryogenesis. Some chapters deal with the morphogenic, structural and developmental, physiological and biochemical, and molecular biological aspects of the subject. Chapters are also devoted to haploid embryogenesis, asexual embryogenesis in nature, zygotic embryogenesis, and zygotic embryo culture. Detailed tables summarizing successful somatic embryogenesis in all vascular plants are also included. This book, therefore, brings together previously scattered information to provide an indispensable reference book for both active researchers, graduate students and anyone interested in this aspect of tissue culture technology and plant development.

Book excerpt: SCIENCE AND EMPIRES: FROM THE INTERNATIONAL COLLOQUIUM TO THE BOOK Patrick PETITJEAN, Catherine JAMI and Anne Marie MOULIN The International Colloquium "Science and Empires - Historical Studies about Scientific De velopment and European Expansion" is the product of an International Colloquium, "Sciences and Empires - A Comparative History of Scien tific Exchanges: European Expansion and Scientific Development in Asian, African, American and Oceanian Countries". Organized by the REHSEIS group (Research on Epistemology and History of Exact Sciences and Scientific Institutions) of CNRS (National Center for Scientific Research), the colloquium was held from 3 to 6 April 1990 in the UNESCO building in Paris. This colloquium was an idea of Professor Roshdi Rashed who initiated this field of studies in France some years ago, and proposed "Sciences and Empires" as one of the main research programmes for the The project to organize such a colloquium was a bit REHSEIS group. of a gamble. Its subject, reflected in the title "Sciences and Empires", is not a currently-accepted sub-discipline of the history of science; rather, it refers to a set of questions which found autonomy only recently. The terminology was strongly debated by the participants and, as is frequently suggested in this book, awaits fuller clarification.

Download or read book On Human Nature written by Armin Grunwald and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern molecular technology in the so-called life sciences (biology as weil as medicine) allows today to approach and manipulate living beings in ways and to an extent wh ich not too long aga seemed Utopian. The empirical progress promises further and even more radical developments in the future, and it is at least often claimed that this kind of research will have tremendeous etfects on and for all of humanity, for example in the areas of food production, transplantation medicine (including stem cell research and xenotransplantation), (therapeutic) genetic manipulation and (cell-line) cloning (of cell lines or tissues), and of biodiversity conservation-strategies. At least in Western, industrialized countries the development of modern sciences led to a steady increase of human health, well-being and quality of life. However, with the move to make the human body itself an object of scientific research interests, the respective scientific descriptions resulted in changes in the image that human beings have of themselves. Scientific progress has led to a startling loss of traditional human self-understanding. This development is in contrast to an under standing according to which the question what it means to be "human" is treated in the realm of philosophy. And indeed, a closer look reveals that - without denying the value of scientitic progress - science cannot replace the philosophical approach to anthropological questions.
