Advanced Green Chemistry - Part 2: From Catalysis To Chemistry Frontiers
Green Chemistry has evolved in response to several environmental issues in the second half of the last century, mostly due to the almost freely expanding chemical, petrochemical, and pharmaceutical industries. During the past two decades Green Chemistry grew rapidly and we can now consider this area as a mature and powerful field. Tremendous development has taken place in many important areas including renewable energy and resources, reaction environments, catalysis, synthesis, chemical biology, green polymers, and facile recycling. The combination of Green Chemistry with engineering, biology, toxicology, and physics will lead to novel interdisciplinary systems, which can now lift Green Chemistry to the next, advanced level. The editors have assembled authors among the best specialists of this growing area of research. This collection of reviews and perspectives provides an exciting vision of the more recent developments in Green Chemistry. The contents of this book illustrate the breath of the field and its role to address environmental issues. This volume will serve as a book of reference showing a panoramic view of the field and a preview of its future direction, as well as a book of inspiration for those aiming to further advance its frontiers. This volume emphasizes on the most recent developments in green catalysis, bio-sourced polymers and the study of continental organic matter for a better understanding of the carbon geochemical cycle.

Stigmatic Optics
This book examines the concept of stigmatism from its base to the most fundamental stigmatic systems. The book begins with Maxwell's equations, before continuing with the wave equation, the eikonal equation and the ray equation. The eikonal equation is also studied with the formalism of the calculation of variations and the concept of stigmatism. Once the foundations of stigmatism have been established, the book focuses on fundamental stigmatic systems, Cartesian ovals and stigmatic lenses. Step by step, the derivations of these systems are obtained and illustrative examples of all their cases are shown. Through the study of these systems, the uniqueness of stigmatism is formulated, and the implications of this uniqueness are presented at the end of the book. This book is an excellent guide for producers of lenses and optical products, and academics in lens design and optics.<br><br><b><u>Key Features</u></b><br><div><ul><li>Includes examples throughout</li><li>Presents problems proposed to be solved by students as well as codes and algorithms in every chapter</li><li>Discusses the physical concepts needed, then focuses on the mathematical tools needed to understand the eikonal and the close form solution of the stigmatic optical systems</li><li>A great reference for research centres, optical based societies, optics journals, universities and optical based companies.</li></ul></div>

The Secret Life of Stars
Astrophysics made fun!' Pam Melroy, former astronaut and space shuttle commander
'The most enjoyable stroll through the cosmos' Gerry Griffin, former flight director, Apollo Mission Control
We all know the Sun, the powerhouse of our solar system, but what about Luyten's Flare, the Rosino-Zwicky Object or Chanal's variable star? For those whose curiosity takes them far beyond Earth's atmosphere, The Secret Life of Stars offers a personal and readily understood introduction to some of the Galaxy's most remarkable stars.
Each chapter connects us to the various different and unusual stars and their amazing characteristics and attributes, from pulsars, blue stragglers and white dwarfs to cannibal stars and explosive supernovae. With chapter illustrations by Eirian Chapman, this book brings to life the remarkable personalities of these stars, reminding readers what a diverse and unpredictable universe we live in and how fortunate we are to live around a stable star, our Sun.
Employment of English
What sorts of cultural criticism are teachers and scholars to produce, and how can that criticism be «employed» in the culture at large? In recent years, debates about the role and direction of English departments have mushroomed into a broader controversy over the public legitimacy of literary criticism. At first glance this might seem odd: few taxpayers and legislators care whether the nation's English professors are doing justice to the project of identifying the beautiful and the sublime. But in the context of the legitimation crisis in American higher education, the image of English departments has in fact played a major role in determining public attitudes toward colleges and college faculty. Similarly, the changing economic conditions of universities have prompted many English professors to rethink their relations to their «clients,» asking how literary study can serve the American public. What sorts of cultural criticism are teachers and scholars to produce, and how can that criticism be «employed» in the culture at large? In The Employment of English, Michael Bérubé, one of our most eloquent and gifted critics, examines the cultural legitimacy of literary study. In witty, engaging prose, Bérubé asserts that we must situate these questions in a context in which nearly half of all college professors are part-time labor and in which English departments are torn between their traditional mission of defining movements of literary history and protocols of textual interpretation, and their newer tasks of interrogating wider systems of signification under rubrics like «gender,» «hegemony,» «rhetoric,» «textuality» (including film and video), and «culture.» Are these new roles a betrayal of the field's founding principles, in effect a short-sighted sell-out of the discipline? Do they represent little more that an attempt to shore up the status of–and student enrollments in–English? Or are they legitimate objects of literary study, in need of public support? Simultaneously investigating the economic and the intellectual ramifications of current debates, The Employment of English provides the clearest and most condensed account of this controversy to date.
