Molecular Cell Biology presents the key concepts in cell biology and their experimental underpinnings. The authors, all world-class researchers and teachers, incorporate medically relevant examples where appropriate to help illustrate the connections between cell biology and health and human disease. As always, a hallmark of Molecular Cell Biology is the use of experiments to engage students in the history of cell biology and the research that has contributed to the field.The new edition of Molecular Cell Biology introduces a new member to our author team, respected researcher and teacher Angelika Amon of the Massachusetts Institute of Technology. Dr. Amon is an Investigator at the Howard Hughes Medical Institute as well as a member of the Koch Institute for Integrative Cancer Research and the National Academy of Sciences. Her laboratory studies the molecular mechanisms that govern chromosome segregation during mitosis and meiosis and the consequences when these mechanisms fail during normal cell proliferation and cancer development.In the new edition, the authors have scrutinized every chapter with an eye toward bringing out key concepts and making connections easier to follow. Perennially challenging topics, such as cellular energetics, cell signaling and immunology, have been revised to improve student understanding. Coverage of developmental biology has been streamlined to focus on just those key areas central to cell biology courses. Every figure in the book was reconsidered and, if possible, simplified to highlight key lessons. Revised end-of-chapter materials include new questions, including additional Analyze the Data problems to give students added practice at interpreting experimental evidence.The result is a book that balances currency and experimental focus with attention to clarity, organization, and pedagogy.

This new, third volume of Cohen-Tannoudji''s groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloe * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications

This book is a treatise on time and on background independence in physics. It first considers how time is conceived of in each accepted paradigm of physics: Newtonian, special relativity, quantum mechanics (QM) and general relativity (GR). Substantial differences are moreover uncovered between what is meant by time in QM and in GR. These differences jointly source the Problem of Time: Nine interlinked facets which arise upon attempting concurrent treatment of the QM and GR paradigms, as is required in particular for a background independent theory of quantum gravity. A sizeable proportion of current quantum gravity programs - e.g. geometrodynamical and loop quantum gravity approaches to quantum GR, quantum cosmology, supergravity and M-theory - are background independent in this sense. This book's foundational topic is thus furthermore of practical relevance in the ongoing development of quantum gravity programs. This book shows moreover that eight of the nine facets of the Problem of Time already occur upon entertaining background independence in classical (rather than quantum) physics.By this development, and interpreting shape theory as modelling background independence, this book further establishes background independence as a field of study. Background independent mechanics, as well as minisuperspace (spatially homogeneous) models of GR and perturbations thereabout are used to illustrate these points.

Thefirst book that addresses the issues of global change from a true Earth systemsperspective,this new book offers a solid emphasis on lessons from Earthhistory that may guide decision-making in the future. Offersan innovative systems theory approach that allows for a new way of organizinginformation from a variety of disciplines as well as of predicting responses ofsystems to disturbance. Utilizes an Earth history perspective that links theEarth sciences closely with modern global change problems. Includes two boxedfeatures throughout the book that address topical issues related to thematerial in the text, of high appeal and that discuss advanced, especiallyquantitative, treatments. Features several computer modules available on theWorld Wide Web and free when packaged with the book. For Earthscientists who would like a formal introduction to Earth Systems Science.

So you plan on majoring in Biology. Why wouldn't you want to use what's been described as the best majors' text for learning the subject? That's what you get with Solomon, Martin, Martin and Berg's BIOLOGY. Working like a built-in study guide, the integrated learning system guides you through the material, starting with key concepts for each chapter and learning objectives for each section. Check your grasp of key points before moving on by answering Checkpoint questions at the end of each section. Reinforce your understanding of the learning objectives with chapter summaries, followed by the opportunity to test your new knowledge. To further help you "get it," the eleventh edition uses themes--among others, the evolution of life and the inter-relationship of structure and function--as well as interactive online and multimedia resources. Ready to go for it? Then go for BIOLOGY.

Esta es la cuarta edición de un tratado tecnico sobre Viticultura de amplio contenido, que supone una gran satisfacción, tanto por el exito alcanzado en ediciones precedentes, como por corresponder a un gran esfuerzo realizado para redactar, revisar y actualizar su contenido, esperando que la presente tenga tambien una favorable acogida. Ambos autores han sido acreedores a seis premios de Viticultura y Enologia otorgados por el maximo ente mundial en estas materias, la Organizacion Internacional de la Viña y el Vino (OIV), que confirma su solvencia docente y profesional, constituyendo un hecho sin parangon en el actual sector Vitivinicola a nivel mundial. a

This graduate-level textbook provides a unified viewpoint of quantum information theory that merges key topics from both the information-theoretic and quantum- mechanical viewpoints. The text provides a unified viewpoint of quantum information theory and lucid explanations of those basic results, so that the reader fundamentally grasps advances and challenges. This unified approach makes accessible such advanced topics in quantum communication as quantum teleportation, superdense coding, quantum state transmission (quantum error-correction), and quantum encryption.

It is well known that infrastructure development projects can boost the economy and reduce the cost of trade in both developing and developed economies however infrastructure projects can also cause biodiversity loss This book is the result of an important biodiversity survey conducted along an East African railway in Tanzania The building of the railway still under construction has already led to habitat loss habitat degradation and landscape change which may have affected biodiversity The book includes recommendations to mitigate the effect of railway construction by protecting biodiversity and ecosystem services which could have major implications across Africa and other regions The area covered by the survey focuses on the Standard Gauge Railway SGR running through the Pugu and Ruvu South Forest Reserves towards Maktupora Dodoma plus data on large mammals through to Isaka Shinyanga The Pugu forests boast high biodiversity of both flora and fauna some of which are endemic to the area There are both plant and animal species that are of major conservation concern so there is urgent need to consolidate information to help formulate suitable conservation measures The data collected covers plants invertebrates amphibians birds and mammals for terrestri

This book highlights key laws and policies that have shaped western agriculture using stories of famous and lesser known individual and communal agriculture models It highlights problems these laws have created particularly related to access and ownership of resources and makes practical recommendations for legal and policy reform
