When Reproduction meets Ageing questions the nature of reproductive ageing and reproductive biomedicine.
The term vitamin E describes a family of eight antioxidants, four tocopherols, alpha-, beta-, gamma- and delta-, and four tocotrienols (also alpha-, beta-, gamma- and delta-). Alpha-tocopherol is the only form of vitamin E that is actively maintained in the human body and is therefore, the form of vitamin E found in the largest quantities in the blood and tissue (1). Alpha-tocopherol is the form of vitamin E that appears to have the greatest nutritional significance. This volume presents leading-edge research in this important field.
This book is a special collection of articles dedicated to the preparation and characterization of nanoporous materials, such as zeolitic-type materials, mesoporous silica (SBA-15, MCM-41, and KIT-6), mesoporous metallic oxides, metal–organic framework structures (MOFs), and pillared clays, and their applications in adsorption, catalysis, and separation processes. This book presents a global vision of researchers from international universities, research centers, and industries working with nanoporous materials and shares the latest results on the synthesis and characterization of such materials, which have given rise to the special interest in their applications in basic and industrial processes.
This book presents a small sample of the physiological changes and human health risks that have been observed in low Earth orbit, and that will undoubtedly be magnified with extended exploration operations to deep space. The book presents the evidence to date and offers a glimpse at what will be needed to take humanity further into deep space than ever before.
During the twentieth century, genes were considered the controlling force of life processes, and the transfer of DNA the definitive explanation for biological heredity. Such views shaped the politics of human heredity: in the eugenic era, controlling heredity meant intervening in the distribution of "good" and "bad" genes. However, since the turn of the twenty-first century, this centrality of genes has been challenged by a number of "postgenomic" disciplines. The rise of epigenetics in particular signals a shift from notions of biological fixedness to ideas of plasticity and "impressionability" of biological material. This book investigates a long history of the beliefs about the plasticity...
This volume addresses the need for a more considered and systematic approach to teacher education and training in Computer-Assisted Language Learning (CALL), in all its forms: Technology Enhanced Language Learning, Network-Based Language Learning, Information and Communication Technologies for Language Learning and so on. The 20 chapters of the book are divided into five parts: (1) foundations of teacher education in CALL; (2) CALL degree programs; (3) CALL pre-service courses; (4) CALL in-service projects, courses, and workshops; (5) alternatives to formal CALL training. The chapters cover a broad range of levels, environments, countries, and languages. Rather than simply offering inspired speculation, the chapters provide practical information to readers, reporting on what has actually been done in a wide variety of teacher education programs and courses around the world. In many cases, the chapters describe how programs and courses have evolved, and include either qualitative or quantitative research, or both, to inform the structure of CALL courses, tasks and activities.
In this thoroughly revised and expanded third edition of the highly praised classic, The Principles of Clinical Cytogenetics, a panel of hands-on experts update their descriptions of the basic concepts and interpretations involved in chromosome analysis to include the many advances that have occurred in the field. Among the highlights are a full chapter devoted to advances in chromosome microarray, soon to become a standard of care in this field, as well as an update on chromosome nomenclature as reflected in ISCN 2009. Other features include an update on automation to reflect the current state of the art, an update on hematopoietic neoplasms to reflect the new WHO guidelines, and updates on all regulatory changes that have been implemented. Cutting edge and readily accessible, The Principles of Clinical Cytogenetics, Third Edition offers physicians who depend on the cytogenetics laboratory for the diagnosis of their patients, students in cytogenetics programs, graduate and medical students studying for board examinations, cytogenetics technologists, and cytogeneticists a clear understanding of what happens in the cytogenetics laboratory to facilitate accurate and timely diagnoses.
Marble in Ancient Greece and Rome: Geology, Quarries, Commerce, Artifacts Marble remains the sine qua non raw material of the an cient Greeks and Romans. Beginning in the Bronze Age sculptu re began in marble and throughout classical times the most im portant statues, reliefs, monuments and inscriptions were made of it. Yet, quarry sources changed in time as preferences for different marbles were influenced by local traditions, the pos sibilities of transport, esthetic tastes, and economics. Marble studies and the identification of the provenance of marble can thus reveal much about Greek and Roman history, trade, esthe tics and technology. Persons in many disciplines are studying various as...
