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.

"Frightening...Firestorm comes alive when Struzik discusses the work of offbeat scientists." —New York Times Book Review "Comprehensive and compelling." —Booklist "A powerful message." —Kirkus "Should be required reading." —Library Journal For two months in the spring of 2016, the world watched as wildfire ravaged the Canadian town of Fort McMurray. Firefighters named the fire “the Beast.” It acted like a mythical animal, alive with destructive energy, and they hoped never to see anything like it again. Yet it’s not a stretch to imagine we will all soon live in a world in which fires like the Beast are commonplace. A glance at international headlines shows a remarkable increase in higher temperatures, stronger winds, and drier lands– a trifecta for igniting wildfires like we’ve rarely seen before. This change is particularly noticeable in the northern forests of the United States and Canada. These forests require fire to maintain healthy ecosystems, but as the human population grows, and as changes in climate, animal and insect species, and disease cause further destabilization, wildfires have turned into a potentially uncontrollable threat to human lives and livelihoods. Our understanding of the role fire plays in healthy forests has come a long way in the past century. Despite this, we are not prepared to deal with an escalation of fire during periods of intense drought and shorter winters, earlier springs, potentially more lightning strikes and hotter summers. There is too much fuel on the ground, too many people and assets to protect, and no plan in place to deal with these challenges. In Firestorm, journalist Edward Struzik visits scorched earth from Alaska to Maine, and introduces the scientists, firefighters, and resource managers making the case for a radically different approach to managing wildfire in the 21st century. Wildfires can no longer be treated as avoidable events because the risk and dangers are becoming too great and costly. Struzik weaves a heart-pumping narrative of science, economics, politics, and human determination and points to the ways that we, and the wilder inhabitants of the forests around our cities and towns, might yet flourish in an age of growing megafires.

This “elegant and haunting novel of war, art and memory" (The Independent) award-winning novel from the acclaimed author of The Gift of Rain follows the only Malaysian survivor of a Japanese wartime camp as she begins working for an exiled former gardener of the Emporer. Malaya, 1951. Yun Ling Teoh, the scarred lone survivor of a brutal Japanese wartime camp, seeks solace among the jungle-fringed tea plantations of Cameron Highlands. There she discovers Yugiri, the only Japanese garden in Malaya, and its owner and creator, the enigmatic Aritomo, exiled former gardener of the emperor of Japan. Despite her hatred of the Japanese, Yun Ling seeks to engage Aritomo to create a garden in memory of her sister, who died in the camp. Aritomo refuses but agrees to accept Yun Ling as his apprentice "until the monsoon comes." Then she can design a garden for herself. As the months pass, Yun Ling finds herself intimately drawn to the gardener and his art, while all around them a communist guerilla war rages. But the Garden of Evening Mists remains a place of mystery. Who is Aritomo and how did he come to leave Japan? And is the real story of how Yun Ling managed to survive the war perhaps the darkest secret of all?

In the years between the world wars, Manhattan's Fourteenth Street-Union Square district became a center for commercial, cultural, and political activities, and hence a sensitive barometer of the dramatic social changes of the period. It was here that four urban realist painters--Kenneth Hayes Miller, Reginald Marsh, Raphael Soyer, and Isabel Bishop--placed their images of modern "new women." Bargain stores, cheap movie theaters, pinball arcades, and radical political organizations were the backdrop for the women shoppers, office and store workers, and consumers of mass culture portrayed by these artists. Ellen Wiley Todd deftly interprets the painters' complex images as they were refracted through the gender ideology of the period. This is a work of skillful interdisciplinary scholarship, combining recent insights from feminist art history, gender studies, and social and cultural theory. Drawing on a range of visual and verbal representations as well as biographical and critical texts, Todd balances the historical context surrounding the painters with nuanced analyses of how each artist's image of womanhood contributed to the continual redefining of the "new woman's" relationships to men, family, work, feminism, and sexuality.

Paul Klee was endowed with a rich and many-sided personality that was continually spilling over into forms of expression other than his painting and that made him one of the most extraordinary phenomena of modern European art. These abilities have left their record in the four intimate Diaries in which he faithfully recorded the events of his inner and outer life from his nineteenth to his fortieth year. Here, together with recollections of his childhood in Bern, his relations with his family and such friends as Kandinsky, Marc, Macke, and many others, his observations on nature and people, his trips to Italy and Tunisia, and his military service, the reader will find Klee's crucial experience with literature and music, as well as many of his essential ideas about his own artistic technique and the creative process.

“Groundbreaking in its call to reconsider our approach to the slow rhythm of time in the very concrete realms of environmental health and social justice.” —Wold Literature Today The violence wrought by climate change, toxic drift, deforestation, oil spills, and the environmental aftermath of war takes place gradually and often invisibly. Using the innovative concept of "slow violence" to describe these threats, Rob Nixon focuses on the inattention we have paid to the attritional lethality of many environmental crises, in contrast with the sensational, spectacle-driven messaging that impels public activism today. Slow violence, because it is so readily ignored by a hard-charging capitalism, exacerbates the vulnerability of ecosystems and of people who are poor, disempowered, and often involuntarily displaced, while fueling social conflicts that arise from desperation as life-sustaining conditions erode. In a book of extraordinary scope, Nixon examines a cluster of writer-activists affiliated with the environmentalism of the poor in the global South. By approaching environmental justice literature from this transnational perspective, he exposes the limitations of the national and local frames that dominate environmental writing. And by skillfully illuminating the strategies these writer-activists deploy to give dramatic visibility to environmental emergencies, Nixon invites his readers to engage with some of the most pressing challenges of our time.

Made to Break is a history of twentieth-century technology as seen through the prism of obsolescence. Giles Slade explains how disposability was a necessary condition for America's rejection of tradition and our acceptance of change and impermanence. This book gives us a detailed and harrowing picture of how, by choosing to support ever-shorter product lives, we may well be shortening the future of our way of life as well.
