This work presents a definitive interpretation of the current status of and future trends in natural products—a dynamic field at the intersection of chemistry and biology concerned with isolation, identification, structure elucidation, and chemical characteristics of naturally occurring compounds such as pheromones, carbohydrates, nucleic acids, and enzymes. With more than 1,800 color figures, Comprehensive Natural Products II features 100% new material and complements rather than replaces the original work (©1999). Reviews the accumulated efforts of chemical and biological research to understand living organisms and their distinctive effects on health and medicine Stimulates new ideas am...
Black Internationalist Feminism examines how African American women writers affiliated themselves with the post-World War II Black Communist Left and developed a distinct strand of feminism. This vital yet largely overlooked feminist tradition built upon and critically retheorized the postwar Left's "nationalist internationalism," which connected the liberation of Blacks in the United States to the liberation of Third World nations and the worldwide proletariat. Black internationalist feminism critiques racist, heteronormative, and masculinist articulations of nationalism while maintaining the importance of national liberation movements for achieving Black women's social, political, and econ...
How new are the high Tc superconductors, as compared to the conventional low Tc ones? In what sense are these oxides different from regular metals in their normal state? How different is the mechanism for high Tc superconductivity from the well-known electron-phonon interaction that explains so well superconductivity in metals and alloys? What are the implications of the new features of the high Tc oxides for their practical applications? This interesting book aims to provide some answers to those questions, drawing particularly on similarities between the high Tc oxides and granular superconductors, which also present a short coherence length and a small superfluid density.
A wide range of progress in materials development [single crystals, ceramics, thin films, wire and tapes] is reported in the 169 papers in this volume. The main focus of the papers is in attaining a better understanding of the relationship between microstructure and electrical properties. Invited papers cover topics such as the effects of substitution and doping; multilayers; nanostructure characterisation; electric field effects in High Tc Superconductors [HTS]; surface stability; critical currents; flux pinning and magnetooptic imaging of flux patterns; effects of irradiation induced defects; properties and preparation of materials; microwave properties and electronic devices. A clearly broadened basis for understanding processes and mechanisms in [HTS] is portrayed. Appreciable progress has been achieved in the reproducible manufacturing of high quality materials supported by very efficient methods in microstructural analysis. This essential improvement is reflected in the increased number of practical devices encouraging the use of HTS in applications for electronics and power engineering, all of which are reviewed in depth in this work.
Of the myriad of heterocycles known to man, the indole ring stands foremost for its remarkably versatile chemistry, its enormous range of biological activities, and its ubiquity in the terrestrial and marine environments. The indole ring continues to be discovered in natural products and to be employed in man-made pharmaceuticals and other materials. Given the enormous resurgence in indole ring synthesis over the past decade — highlighted by the power of transition metal catalysis — this authoritative guide addresses the need for a comprehensive presentation of the myriad of methods for constructing the indole ring, from the ancient to the modern, and from the obscure to the well-known. ...
Following in the long-standing tradition of excellence established by this serial, this volume provides a focused look at contemporary applications. High Tc superconducting thin films are discussed in terms of ion beam and sputtering deposition, vacuum evaporation, laser ablation, MOCVD, and other deposition processes in addition to their ultimate applications. Detailed treatment is also given to permanent magnet thin films, lateral diffusion and electromigration in metallic thin films, and fracture and cracking phenomena in thin films adhering to high-elongation substrates.
This reference book provides updated information about different immunomodulators for managing fish health and sustainable aquaculture. Immunomodulators are dietary additives that enhance innate defense mechanisms and increase resistance against specific pathogens and diseases. The book covers the different types of immunostimulants, their modes of action, and their efficacies. It also reviews safety concerns, ethical regulations, limitations, and outreach to farmers. It discusses the application of herbal immunomodulators, antioxidants, pre- and pro-biotics, in disease management. Features: • Reviews the pressing topic of reduction of antibiotic use in aquaculture • Discusses herbal immunomodulators, nutrients, antioxidants and pre- and pro-biotics • Covers the topic of progressive immunomodulation using nanotechnology • Discusses fish health management in the ever-growing aquaculture industry • Includes natural and synthetic immunomodulators The book is meant for researchers and industry experts in aquaculture, fisheries science, and veterinary medicine.
