Phytochemical Methods


Book Description

While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork.




From Puritanism to Postmodernism


Book Description

Widely acknowledged as a contemporary classic that has introduced thousands of readers to American literature, From Puritanism to Postmodernism: A History of American Literature brilliantly charts the fascinating story of American literature from the Puritan legacy to the advent of postmodernism. From realism and romanticism to modernism and postmodernism it examines and reflects on the work of a rich panoply of writers, including Poe, Melville, Fitzgerald, Pound, Wallace Stevens, Gwendolyn Brooks and Thomas Pynchon.

A tour de force of both literary and historical writing, this Routledge Classics edition includes a new preface by co-author Richard Ruland, a new foreword by Linda Wagner-Martin and a fascinating interview with Richard Ruland, in which he reflects on the nature of American fiction and his collaboration with Malclolm Bradbury. It is published here for the first time.




Seed-borne plant virus diseases


Book Description

Seeds provide an efficient means in disseminating plant virus and viroid diseases. The success of modern agriculture depends on pathogen free seed with high yielding character and in turn disease management. There is a serious scientific concern about the transmission of plant viruses sexually through seed and asexually through plant propagules. The present book provides the latest information along with the total list of seed transmitted virus and viroid diseases at global level including, the yield losses, diagnostic techniques, mechanism of seed transmission, epidemiology and virus disease management aspects. Additional information is also provided on the transmission of plant virus and virus-like diseases through vegetative propagules. It is also well known that seed transmitted viruses are introduced into new countries and continents during large-scale traffic movements through infected germplasm and plant propogules. The latest diagnostic molecular techniques in different virus-host combinations along with disease management measures have been included. The book shall be a good reference source and also a text book to the research scientists, teachers, students of plant pathology, agriculture, horticulture, life sciences, green house managers, professional entrepreneurs, persons involved in quarantines and seed companies. This book has several important features of seed transmitted virus diseases and is a good informative source and thus deserves a place in almost all university libraries, seed companies and research organizations.

A Revision of the Dulcamaroid Clade of Solanum L. (Solanaceae)


Book Description

This volume is a monograph of the 47 species of the Dulcamaroid clade of the large and diverse genus Solanum. Species in the group occur in North, Central and South America, and in Europe and Asia. The group is most species-rich in Peru and Brazil, and three of the component species, Solanum laxum of Brazil, Solanum seaforthianum of the Caribbean and and Solanum crispum of Chile are cultivated in many parts of the world. All species are illustrated and a distribution map of each is provided. All names are typified and nomenclatural and bibliographic details for all typifications presented. One new species from Ecuador is described. The monograph is the first complete taxonomic treatment of these species since the worldwide monograph of Solanum done by the French botanist Michel-Felix Dunal in 1852.




More Readings From One Man's Wilderness


Book Description

Throughout history, many people have escaped to nature either permanently or temporarily to rest and recharge. Richard L. Proenneke, a modern-day Henry David Thoreau, is no exception. Proenneke built a cabin in Twin Lakes, Alaska in 1968 and began thirty years of personal growth, which he spent growing more connected to the wilderness in which he lived. This guide through Proenneke’s memories follows the journey that began with One Man’s Wilderness, which contains some of Proenneke’s journals. It continues the story and reflections of this mountain man and his time in Alaska. The editor, John Branson, was a longtime friend of Proenneke’s and a park historian. He takes care that Proenneke’s journals from 1974-1980 are kept exactly as the author wrote them. Branson’s footnotes give a background and a new understanding to the reader without detracting from Proenneke’s style. Anyone with an interest in conservation and genuine wilderness narratives will surely enjoy and treasure this book.




The Travels of Sir John Mandeville


Book Description

The Travels of Sir John Mandeville is the chronicle of the alleged Sir John Mandeville, an explorer. His travels were first published in the late 14th century, and influenced many subsequent explorers such as Christopher Columbus.




The Book of John Mandeville


Book Description

The Book of John Mandeville has tended to be neglected by modern teachers and scholars, yet this intriguing and copious work has much to offer the student of medieval literature, history, and culture. [It] was a contemporary bestseller, providing readers with exotic information about locales from Constantinople to China and about the social and religious practices of peoples such as the Greeks, Muslims, and Brahmins. The Book first appeared in the middle of the fourteenth century and by the next century could be found in an extraordinary range of European languages: not only Latin, French, German, English, and Italian, but also Czech, Danish, and Irish. Its wide readership is also attested by the two hundred fifty to three hundred medieval manuscripts that still survive today. Chaucer borrowed from it, as did the Gawain-poet in the Middle English Cleanness, and its popularity continued long after the Middle Ages.




Barbie Chang


Book Description

"With astringent understatement and wry economy, with nuance and intelligence and an enviable command of syntax and poetic line, Victoria Chang dissects the venerable practices of cultural piety and self-regard. She is a master of the thumbnail narrative. She can wield a dark eroticism. She is determined to tackle subject matter that is not readily subdued to the proportions of lyric. Her talent is conspicuous."—Linda Gregerson "Chang's voice is equal parts searing, vulnerable, and terrified."—American Poets Barbie Chang, Victoria Chang explores racial prejudice, sexual privilege, and the disillusionment of love through a reimagining of Barbie—perfect in the cultural imagination yet repeatedly falling short as she pursues the American dream. This energetic string of linked poems is full of wordplay, humor, and biting social commentary involving the quote-unquote speaker, Barbie Chang, a disillusioned Asian-American suburbanite. By turns woeful and passionate, playful and incisive, these poems reveal a voice insisting that "even silence is not silent." From "Barbie Chang Lives": Barbie Chang lives on Facebook has a house on Facebook street so she can erase herself Facebook is a country with no trees it allows her to believe people love her don't want to cover her Barbie Chang . . . Victoria Chang is the author of three previous poetry books. In 2013, she won the PEN Center USA Literary Award and a California Book Award. Chang teaches poetry at Chapman University and lives in Southern California.
