Download or read book Phytochemical Methods written by Jeffrey B. Harborne and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Command Of The Air written by General Giulio Douhet and published by Pickle Partners Publishing. This book was released on 2014-08-15 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the pantheon of air power spokesmen, Giulio Douhet holds center stage. His writings, more often cited than perhaps actually read, appear as excerpts and aphorisms in the writings of numerous other air power spokesmen, advocates-and critics. Though a highly controversial figure, the very controversy that surrounds him offers to us a testimonial of the value and depth of his work, and the need for airmen today to become familiar with his thought. The progressive development of air power to the point where, today, it is more correct to refer to aerospace power has not outdated the notions of Douhet in the slightest In fact, in many ways, the kinds of technological capabilities that we enjoy as a global air power provider attest to the breadth of his vision. Douhet, together with Hugh “Boom” Trenchard of Great Britain and William “Billy” Mitchell of the United States, is justly recognized as one of the three great spokesmen of the early air power era. This reprint is offered in the spirit of continuing the dialogue that Douhet himself so perceptively began with the first edition of this book, published in 1921. Readers may well find much that they disagree with in this book, but also much that is of enduring value. The vital necessity of Douhet’s central vision-that command of the air is all important in modern warfare-has been proven throughout the history of wars in this century, from the fighting over the Somme to the air war over Kuwait and Iraq.

Download or read book In Search of Lost Roses written by Thomas Christopher and published by University of Chicago Press. This book was released on 2002-05 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once upon a time—before the 1860s—people loved old roses like "Pearl of Gold," "Marchionesse of Lorne," or "Autumn Damask." Then along came the hybrid tea roses, which were easier to arrange, more dramatic, and longer-blooming, and the old roses were all but forgotten. Now the lovely, subtle-hued, richly perfumed old roses are making a comeback, thanks to the efforts of a stubborn band of eccentric characters who rescued them from back alleys, ramshackle cottages, and overgrown graveyards across the country. Thomas Christopher tells us the fascinating stories of the old roses—how they were created and made their way to America—and the unforgettable people who "rustle" them from abandoned lots and secret gardens today, revelling in the mystery of an "unknown yellow."

Available in PDF, EPUB and Kindle. Book excerpt: . Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.

Download or read book The Carnivorous Plants written by Barrie Edward Juniper and published by . This book was released on 1989 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants, as is now becoming widely recognised, exploit animals in almost as many ways as animals use plants; only rarely, however, do they eat animals in the sense of catching, holding, and devouring prey. The manner, however, in which they function as carnivores grants insights into plant form, function, and evolution not otherwise readily available. The diversity of morphological, biochemical, and commensal features generates both the lay and the scientific interest in this diverse group. The carnivorous plants exhibit features which are common to many other non-carnivorous plants. However the extent to which these features have developed and the combination of different features in small organs is unique and therefore, can be exploited by using these plants as models for scientific research.

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Download or read book The Waste Books written by Georg Christoph Lichtenberg and published by New York Review of Books. This book was released on 2000-09-30 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: German scientist and man of letters Georg Christoph Lichtenberg was an 18th-century polymath: an experimental physicist, an astronomer, a mathematician, a practicing critic both of art and literature. He is most celebrated, however, for the casual notes and aphorisms that he collected in what he called his Waste Books. With unflagging intelligence and encyclopedic curiosity, Lichtenberg wittily deflates the pretensions of learning and society, examines a range of philosophical questions, and tracks his own thoughts down hidden pathways to disconcerting and sometimes hilarious conclusions. Lichtenberg's Waste Books have been greatly admired by writers as very different as Tolstoy, Einstein, and Andre Breton, while Nietzsche and Wittgenstein acknowledged them as a significant inspiration for their own radical work in philosophy. The record of a brilliant and subtle mind in action, The Waste Books are above all a powerful testament to the necessity, and pleasure, of unfettered thought.

Download or read book The Ladies Book of Etiquette and Manual of Politeness written by Florence Hartley and published by Createspace Independent Publishing Platform. This book was released on 1872 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: In preparing a book of etiquette for ladies, I would lay down as the first rule, "Do unto others as you would others should do to you." You can never be rude if you bear the rule always in mind, for what lady likes to be treated rudely? True Christian politeness will always be the result of an unselfish regard for the feelings of others, and though you may err in the ceremonious points of etiquette, you will never be impolite. Politeness, founded upon such a rule, becomes the expression, in graceful manner, of social virtues. The spirit of politeness consists in a certain attention to forms and ceremonies, which are meant both to please others and ourselves, and to make others pleased with us; a still clearer definition may be given by saying that politeness is goodness of heart put into daily practice; there can be no _true_ politeness without kindness, purity, singleness of heart, and sensibility.
