Download or read book Native Speaker written by Chang-rae Lee and published by Penguin. This book was released on 1996-03-01 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: ONE OF THE ATLANTIC’S GREAT AMERICAN NOVELS OF THE PAST 100 YEARS The debut novel from critically acclaimed and New York Times–bestselling author of On Such a Full Sea and My Year Abroad. In Native Speaker, author Chang-rae Lee introduces readers to Henry Park. Park has spent his entire life trying to become a true American—a native speaker. But even as the essence of his adopted country continues to elude him, his Korean heritage seems to drift further and further away. Park's harsh Korean upbringing has taught him to hide his emotions, to remember everything he learns, and most of all to feel an overwhelming sense of alienation. In other words, it has shaped him as a natural spy. But the very attributes that help him to excel in his profession put a strain on his marriage to his American wife and stand in the way of his coming to terms with his young son's death. When he is assigned to spy on a rising Korean-American politician, his very identity is tested, and he must figure out who he is amid not only the conflicts within himself but also within the ethnic and political tensions of the New York City streets. Native Speaker is a story of cultural alienation. It is about fathers and sons, about the desire to connect with the world rather than stand apart from it, about loyalty and betrayal, about the alien in all of us and who we finally are.
Download or read book Beneficial Microbes Alleviate Climatic Stresses in Plants written by Ying Ma and published by Frontiers Media SA. This book was released on 2019-07-30 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic addresses the mechanisms by which beneficial soil microbes, such as fungi and bacteria, protect their host plant from ‘climatic stresses’ that are increasing due to climate change. We will highlight 1) recent progress in fundamental research, 2) applied studies aimed at promoting sustainable agriculture and environmental remediation, and 3) emerging biotechnologies that promote crop adaptation to climate change. Plants respond to various climatic stresses such as drought, salinity, elevated CO2, and extreme temperatures. These responses induce changes at the molecular, cellular, and physiological levels that restrict the establishment, growth, and development of the plant. Understanding these changes has become an important research goal due to concerns about the adverse effects of climatic stresses on agriculture sustainability, global food security, and even plant-based remediation technologies. Some beneficial soil microorganisms, such as arbuscular mycorrhizal fungi and plant growth promoting bacteria, are able to protect and promote the growth of their host plants by acting as bioprotectants (via induced systemic resistance), biopesticides (via antibiotic functions) and phytostimulators (via triggering hormonal signaling networks). Plant adaptation to various climatic stresses is dynamic and involves complex cross-talk within the regulatory network (e.g. transcription factors, kinase cascades, and signaling molecules). However, the detailed molecular, cellular and physiological mechanisms underlying plant–beneficial microbe interactions in climatic stress adaptation remain largely unknown.

Download or read book The Quest for the Perfect Hive written by Gene Kritsky and published by Oxford University Press. This book was released on 2010-02-24 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beekeeping is a sixteen-billion-dollar-a-year business. But the invaluable honey bee now faces severe threats from diseases, mites, pesticides, and overwork, not to mention the mysterious Colony Collapse Disorder, which causes seemingly healthy bees to abandon their hives en masse, never to return. In The Quest for the Perfect Hive, entomologist Gene Kritsky offers a concise, beautifully illustrated history of beekeeping, tracing the evolution of hive design from ancient Egypt to the present. Not simply a descriptive account, the book suggests that beekeeping's long history may in fact contain clues to help beekeepers fight the decline in honey bee numbers. Kritsky guides us through the progression from early mud-based horizontal hives to the ascent of the simple straw skep (the inverted basket which has been in use for over 1,500 years), from hive design's Golden Age in Victorian England up through the present. He discusses what worked, what did not, and what we have forgotten about past hives that might help counter the menace to beekeeping today. Indeed, while we have sequenced the honey bee genome and advanced our knowledge of the insects themselves, we still keep our bees in hives that have changed little during the past century. If beekeeping is to survive, Kritsky argues, we must start inventing again. We must find the perfect hive for our times. For thousands of years, the honey bee has been a vital part of human culture. The Quest for the Perfect Hive not only offers a colorful account of this long history, but also provides a guide for ensuring its continuation into the future.

Download or read book The Tears of Re written by Gene Kritsky and published by Oxford University Press. This book was released on 2015-10-08 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to Egyptian mythology, when the ancient Egyptian sun god Re cried, his tears turned into honey bees upon touching the ground. For this reason, the honey bee was sacrosanct in ancient Egyptian culture. From the art depicting bees on temple walls to the usage of beeswax as a healing ointment, the honey bee was a pervasive cultural motif in ancient Egypt because of its connection to the sun god Re. Gene Kritsky delivers a concise introduction of the relationship between the honey bee and ancient Egyptian culture, through the lenses of linguistics, archeology, religion, health, and economics. Kritsky delves into ancient Egypt's multifaceted society, and traces the importance of the honey bee in everything from death rituals to trade. In doing so, Kritsky brings new evidence to light of how advanced and fascinating the ancient Egyptians were. This richly illustrated work appeals to a broad range of interests. For archeology lovers, Kritsky delves into the archeological evidence of Egyptian beekeeping and discusses newly discovered tombs, as well as evidence of manmade hives. Linguists will be fascinated by Kritsky's discussion of the first documented written evidence of the honeybee hieroglyph. And anyone interested in ancient Egypt or ancient cultures in general will be intrigued by Kritsky's treatment of the first documented beekeepers. This book provides a unique social commentary of a community so far removed from modern humans chronologically speaking, and yet so fascinating because of the stunning advances their society made. Beekeeping is the latest evidence of how ahead of their times the Egyptians were, and the ensuing narrative is as captivating as every other aspect of ancient Egyptian culture.
Download or read book The Changing Prairie written by Anthony Joern and published by . This book was released on 1995 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grasslands have figured prominently in our North American heritage. Prairies first provided significant barriers to westward expansion, then offered both economic and sociological opportunity, as well as heartache, for settlers. Many artists have gained significant inspiration from the beauty as well as the harshness of these regions and its biota. And, because of ideal climate and soil conditions, these grasslands have provided the agricultural foundation upon which much of the growth and stability of the United States economy rests. Yet, many see North America prairies as beautiful only when manipulated or exploited--green croplands or manicured park lawns are attractive, whereas native grasslands are "those ugly weeds." In the past, plowing virgin prairie could be easily defended on both economic and sociological grounds. And historically, North American prairies must have seemed threatening in both their wildness and vastness. But preservation of these prairies is now an urgent need. This book describes the ecology of the North American prairie and urges conservation measures to protect the remaining North American grasslands. It provides non-economic arguments for the value of prairies, presents a current synthesis of prairie ecology to facilitate the best possible management, and deftly summarizes conservation and management issues, pointing out the costs and benefits of alternative actions. By approaching its subject from a variety of perspectives, including ethical and aesthetic considerations, the book will appeal to environmentalists and conservationists as well as to ecologists, botanists, and conservation biologists.

Download or read book Basic Growth Analysis written by R. Hunt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is intended as an introductory guide to students at all levels on the principles and practice of plant growth analysis. Many have found this quantitative approach to be useful in the description and interpretation of the performance of whole plant systems grown under natural, semi-natural or controlled conditions. Most of the methods described require only simple experimental data and facilities. For the classical approach, GCSE biology and mathematics (or their equivalents) are the only theoretical backgrounds required. For the functional approach, a little calculus and statistical theory is needed. All of the topics regarding the quantitative basis of productivity recently introduced to the Biology A-level syllabus by the Joint Matriculation Board are covered. The booklet replaces my elementary Plant Growth Analysis (1978, London: Edward Arnold) which is now out of print. The presentation is very basic indeed; the opening pages give only essential outlines of the main issues. They are followed by brief, standardized accounts of each growth-analytical concept taken in turn. The illustrations deal more with the properties of well-grown material than with the effects of specific environmental changes, even though that is where much of the subject's interest lies. However, detailed references to the relevant parts of more com prehensive works appear throughout, and a later section on 'Inter relations' adds perspective. Some 'Questions and answers' may also help to show what topics will arise if the subject is pursued further.
