"Brassica" crop species and their allies ("Raphanus, Sinapis, Eruca, " etc.) are important sources of edible roots, stems, leaves, buds and inflorescences, as well as of edible or industrial oils, condiments and forage. Many well known names of plants or plant products, such as kale, cabbage, brocolli, cauliflower, Brussels sprouts, kohl-rabi, Chinese cabbage, turnip, rape, rutabaga, swede, colza or rapeseed, canola, mustard, rocket, etc. are directly associated to this botanical group.
The scientific interest for this botanical group has run parallel to its economical importance, and research achievements in our days would have certainly appeared unimaginable only two decades ago. As the end of the millenium approaches, entirely new fields (transformation, somatic fusion, etc.) have been added to the classical ones. Thus, nobody can doubt the opportuneness of this book, which combines and presents both the basic and applied biological aspects of the Brassica species.

This book is designed to explore the historical and current level of African-American political participation, to assess the fruits of participation, and to provide recommendations for improving the efficacy of African American political participation in the future. Part One focuses on the historic struggle for securing and expanding African-American voting rights; Part Two focuses on the economic, legal, philosophic, and cultural context of African-American politics; Part Three focuses on prospects for African-American politics in the future--particularly the opportunities to develop successful electoral coalitions; and Part Four provides specific recommendations to produce fuller inclusion of African-Americans in the American polity. By providing a balanced account from the national perspective, this volume assesses the historical and current positions of African-Americans in politics throughout the nation. It assesses the impact of the Voting Rights Act of 1965 and clarifies the significance of the struggle for voting rights--and how extensively equitable voting rights have been achieved. By focusing on the economic, legal, and cultural contexts of African-American politics, it evaluates both the potential for success and the built-in limitations of American society in improving black status and everyday life-chances through the political arena. The possibilities for coalition politics are carefully analyzed--providing useful insights into the pitfalls and opportunities of coalition building among minorities and between minorities and various sectors of whites. The book also makes recommendations for increasing African-American political participation and provides strategies for the future. This collection will be invaluable to Black Studies programs and those concerned with current American socio-political developments.

Gradient-Index (GRIN) optics provides a comprehensive and thorough treatment on fundamentals and applications of light propagation through inhomogeneous media. The book can be used both as a classroom text for students in physics and engineering and as a reference for specialists. A description of the phenomena, components and technology used in GRIN Optics are presented. The relationship to lenses, waveguides, optical connections, spatial solitons and vision is demonstrated. Applications of GRIN components and hybrid structures for optical connections, optical sensing and Talbot effect are analyzed.

This book provides a comprehensive and thorough treatment on fundamentals and applications of light propagation through inhomogeneous media. The authors present a description of the phenomena, components and technology used in GRIN Optics, and analyze various applications.

The book gathers the lectures given at the C.I.M.E. summer school "Quantum Cohomology" held in Cetraro (Italy) from June 30th to July 8th, 1997. The lectures and the subsequent updating cover a large spectrum of the subject on the field, from the algebro-geometric point of view, to the symplectic approach, including recent developments of string-branes theories and q-hypergeometric functions.

This book about Texas and its oldest university system is set in communities traversing the State from the Sabine River, to the Piney Woods, to the Hill Country, to the Rio Grande. It is a story of colleges established with a limited mission that, in the course of a century, produced a president, world renowned journalists, entertainers, poets, musicians, writers, and alumni representing the ethnic and cultural diversity of Texas. The story is told by some of the best writers in the State and chronicled by one of the most celebrated artistic photographers in the country. This revised edition has an additional forty new pages with never before seen photography and history of the Texas State University System.

Bulk grown III-V ternary semiconductors of In0.08Ga0.92Sb and In0.15Ga0.85As were investigated through Hall-effect and photoluminescence measurements to determine carrier concentration, mobility, sheet resistivity, and luminescence spectrum. In the past, epitaxial layers of ternary compounds have been grown on binary compound substrates, and thus very limited lattice matched ternary alloys were available. Recently, bulk grown ternary substrates have been developed, and it has presented a renewed interest in using these substrates to grow high quality ternary compounds for use in many next generation optoelectronic devices. The results of photoluminescence (PL) study for the In0.15Ga0.85Sb sample show the exciton bound to neutral acceptor (Ao, X) transition peak at 0.675 eV along with a donor-shallow acceptor pair transitions at 0.650 eV, and the donor-deep acceptor pair transition peak at 0.628 eV

What a mouthful Rain Gomez's book makes you swallow hard, goes down big easy. I can hear a river of blues in lines like "head high, legs sturdy back stalwart against the rough rub of white faced stares as we roll up to Albertsons." There's lyric, prose, confessional, even a classic seafood gumbo recipe, all laced with memories of the red people of the Southeast. Rain Gomez has proven herself the culinary master of poetry. Her book really cooks -LeAnne Howe, author of Shell Shaker (American Book Award) & Evidence of Red Rain C Gomez's poetry is as multi-dimensioned and multi-nationed as her heritage and her book's title. It doesn't get more American than this. --Geary Hobson, author of Plain of Jars and Other Stories & Last of the Ofos
