The Leatherback Turtle


Book Description

The most comprehensive book ever written on leatherback sea turtles. Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nesting beaches and commercial fishing. There are only twenty-nine index beaches in the world where these turtles nest, and there is immense pressure to develop most of them into homes or resorts. At the same time, longline and gill net fisheries continue to overwhelm waters frequented by leatherbacks. In The Leatherback Turtle, James R. Spotila and Pilar Santidrián Tomillo bring together the world’s leading experts to produce a volume that reveals the biology of the leatherback while putting a spotlight on the conservation problems and solutions related to the species. The book leaves us with options: embark on the conservation strategy laid out within its pages and save one of nature’s most splendid creations, or watch yet another magnificent species disappear.




Electroanalysis


Book Description

This is an introduction to the areas of application of electroanalysis, which has an important role with current environmental concerns, both in the laboratory and in the field.




Women In Their Element: Selected Women's Contributions To The Periodic System


Book Description

2019 celebrated the 150th anniversary of Mendeleev's first publication of the Periodic Table of Chemical Elements. This book offers an original viewpoint on the history of the Periodic Table: a collective volume with short illustrated papers on women and their contribution to the building and the understanding of the Periodic Table and of the elements themselves. Few existing texts deal with women's contributions to the Periodic Table. A book on women's work not only helps make historical women chemists more visible; it also sheds light on the multifaceted character of the work on the chemical elements and their periodic relationships. Stories of female input contribute to the understanding of the nature of science, of collaboration as opposed to the traditional depiction of the lone genius.While the discovery of elements is a natural part of this collective work, the book goes beyond discovery histories. Stories of women contributors to the chemistry of the elements also include understanding the concept of element, identifying properties, developing analytical methods, mapping the radioactive series, finding applications of elements, and the participation of women as audiences when new elements were presented at lectures.The book contains chapters on pre-periodic table contributions as well as recent discoveries, unknown stories as well as more famous ones, with an emphasis on work conducted in the late 19th century and early 20th century. Elements from different groups in the periodic table are included, so as to represent a variety of chemical contexts.




The Geometry of Violence


Book Description

?[Praeg] applies the notion of ?sacrificial violence?, as developed by Girard, to the genocide in Rwanda, necklace burnings in South Africa, and the phenomenon of family murders. He shows how there is an underlying logic tying these together, while at the same time resisting a unifying (modernist) discourse which attempts to eradicate the differences. This is an extremely interesting, at times fascinating, text. It is very well written and ... [the] insights gained leave no option but to rethink the manifestation of violence fundamentally.? ?

Venoms to Drugs


Book Description

The pharmaceutical industry has become increasingly interested in biologics from animal venoms as a potential source for therapeutic agents in recent years, with a particularly emphasis on peptides. To date six drugs derived from venom peptides or proteins have been approved by the FDA, with nine further agents currently being investigated in clinical trials. In addition to these drugs in approved or advanced stages of development, many more peptides and proteins are being studied in varying stages of preclinical development. This unique book provides an up to date and comprehensive account of the potential of peptides and proteins from animal venoms as possible therapeutics. Topics covered include chemistry and structural biology of animal venoms, proteomic and transcriptomic approaches to drug discovery, bioassays, high-throughput screens and target identification, and reptile, scorpion, spider and cone snail venoms as a platform for drug development. Case studies are used to illustrate methods and successes and highlight issues surrounding administration and other important lessons that have been learnt from the development of approved therapeutics based on venoms. The first text to focus on this fascinating area and bridging an important gap, this book provides the reader with essential and current knowledge on this fast-developing area. Venoms to Drugs will find wide readership with researchers working in academia and industry working in all medicinal and pharmaceutical areas.

Micromolecular Evolution, Systematics and Ecology


Book Description

For several decades botanists have been impressed by the discovery that the distribution of secondary plant substances follows the general lines of plant relationships. However, it soon became clear that little was to be gained from the study of individual compounds and their natural distribu tion. Therefore, more comprehensive studies were attempt ed in which the secondary chemistry of a major plant group was carefully studied and evaluated in the broader context of comparative phytochemistry. Holger Erdtman's admir able work on Coniferae is the foremost example of this kind. Since then, there has been an upswing in the study of the biosynthesis of secondary plant substances and it has become quite customary to make use of biosynthetic knowledge in interpreting chemosystematic evidence. More over, since taxonomists have insisted that use be made of all potentially available evidence for building classifications, it has been claimed that chemosystematics too should con sider the whole array of constituents present in a major taxon. However, in practice it has proved difficult to utilize fully the potential of natural product chemistry and biosynthetic studies for plant systematics and evolution, because bota nists found themselves rather disorientated by the scattered, often hardly accessible chemical literature and the fact that the chemical evidence was difficult for them to evaluate! Although the pioneering work of E. C.




Synthesis of Solid Catalysts


Book Description

This practical book combines recent progress with a discussion of the general aspects of catalyst preparation. The first part deals with the basic principles of solid catalyst preparation, explaining the main aspects of sol-gel chemistry and interfacial chemistry, followed by such techniques as co-precipitation and immobilization. New tools for catalyst preparation research, including microspectroscopy and high-throughput experimentation, are also taken into account. The second part heightens the practical relevance by providing six case studies on such topics as the preparation of zeolites, hydrotreating catalysts, methanol catalysts and gold catalysts
