The "greening" of industry processes - i.e., making them more sustainable - is a popular and often lucrative trend which has seen increased attention in recent years. Green Chemical Processes, the 2nd volume of Green Chemical Processing, covers the hot topic of sustainability in chemistry with a view to education, as well as considering corporate and environmental interests, e.g. in the context of energy production. The diverse team of authors allows for a balance between these different, but interconnected perspectives. The American Chemical Society's 12 Principles of Green Chemistry are woven throughout this text as well as the series to which this book belongs.

The noteworthy findings and innovative methods of predicting projectile trajectory, introduced in my books Exterior Ballistics: A New Approach (EBNA), Xlibris, 2010; and Exterior Ballistics with Applications (EBA3e), Xlibris, third edition, December 2011, require a methodical approach and further development. As result, the amateurs and professionals interested in exterior ballistics of firearms, and especially in long-range shooting with small arms, have a new book, Exterior Ballistics: The Remarkable Methods (EBRM), that aims to enrich the foundations of modern exterior ballistics and to lessen the complexity of physics and mathematics techniques in use. Exterior Ballistics: The Remarkable Methods is a book that combines and develops further the methods introduced in EBA3e, EBNA, and in the Exterior Ballistics of Small Arms (EBSA, Xlibris 2009). The foundations of the book are mainly the findings and the innovative ballistics methods presented in EBA3e and EBNA. The remarkable methods of exterior ballistics presented in this new book include: The methods of determining the function of resistance G(v) of a given bullet (i=1) using range tables, or the experimental data measurements of three or four coordinates at the points of projectile impact. The model of "Tangent Law of Trajectory Refraction" and the related set of formulas that we use to study the trajectories of projectiles in nonstandard atmosphere. Series expansion method and the techniques of (second to sixth order) parabolas we employ to predict with great accuracy the projectile trajectory. The exceptional Siacci's methods that we apply as well for the projectile trajectory in nonstandard atmosphere and in inclined shooting combined with the tangent law of trajectory refraction. It is important to note that using the similarity laws of fluid dynamics we have obtained the "tangent law of projectile refraction," which represents a progress with respect to "Newton-Snell's law" on projectile refraction. For better understanding of the information presented in the book, the reader should refer to my three preceding books on exterior ballistics, already published by Xlibris, although most of the material is self-contained and clear enough to be accessed and assimilated by a wide range of readers. The system of units used in the book is the International System (SI). For readers that are unfamiliar with the SI system it is not difficult to become accustomed and use the materials presented in the book to benefit from the simple illustrations, exercises, and PC programs that, at the same time, give answers to many problems encountered in practice. My studies and writing work in exterior ballistics intend to find new and simple mathematical models and methods to predict the elements of the projectile trajectory. I believe that I have achieved some good results, which need to be further developed. George Klimi, PhD New York, December 2012 [email protected] [email protected] [email protected]

R5,126 Discovery Miles 51 260 Ships in 12 - 19 working days

In contrast to many other levels of language, there is as yet no comprehensive areal-linguistic description of the segmental phonological properties of the languages of Europe. To complement the synchronic picture of the languages of Europe, it is time to take stock of their phoneme inventories to provide an empirical basis for generalizations about the similarities and dissimilarities of the languages of Europe. The best way to visualize the areal phonology of Europe is that of the Phonological Atlas of Europe (Phon@Europe) which features the isoglosses of phonological phenomena on a plethora of maps. As a prequel to Phon@Europe, this study not only outlines the goals, methodology, sample, and theory of the project but also focuses on loan phonemes whose diffusion across the 210 doculects of the sample yields meaningful patterns. The patterns are indicative of recent processes of convergence which have transformed a diverse phonological mosaic into a superficially homogeneous linguistic area. The developments which have led to the present situation are traced back through the history of the sample languages.

For those of us who live in America who are not filthy rich or poor enough for the government to take care of, we face many challenges. We are a forgotten majority who work every day, pay taxes and honor our flag. We look to the end of our arm to find a helping hand and look for ways to be productive. It often appears that we are the forgotten few of whom no one speaks. It can make a person feel very lonely. In this volume you will find a number of these important issues discussed at length from the perspective of a common working person. Those who would have you believe they have all knowledge can be very blatant, shrill and even obnoxious in their effort to make their position known. This book has turned that around and used the same tactics in an honest effort to show that there is another side to be considered. The author speaks directly and to the point offering many points of personal experiences and circumstances known to all as means to make point and counter point on these subjects. This book could have easily been seventeen books but the author took the position that writing directly and to the point on each subject leaving out all of the usual chatter makes the book more interesting, more readable and much more direct and enjoyable. This book will make you laugh, think, and wonder. The author has a background of many experiences nearly all of which are those of any working person. He was not only a sheep herder, he was a driver and body guard for President Reagan, a business manager truck driver, organized crime investigator, soldier, Realtor and a hundred other things and he designed engineered and built his own home. What is written here is the writers opinion and it will not always agree with the common beliefs and mores of society---A joy to read.

R3,207 Discovery Miles 32 070 Ships in 12 - 19 working days

Scepticism has been the driving force in the development of Greco-Roman culture in the past, and the impetus for far-reaching scientific achievements and philosophical investigation. Early Jewish culture, in contrast, avoided creating consistent representations of its philosophical doctrines. Sceptical notions can nevertheless be found in some early Jewish literature such as the Book of Ecclesiastes. One encounters there expressions of doubt with respect to Divine justice or even Divine involvement in earthly affairs. During the first centuries of the common era, however, Jewish thought, as reflected in rabbinic works, was engaged in persistent intellectual activity devoted to the laws, norms, regulations, exegesis and other traditional areas of Jewish religious knowledge. An effort to detect sceptical ideas in ancient Judaism, therefore, requires a closer analysis of this literary heritage and its cultural context. This volume of collected essays seeks to tackle the question of scepticism in an Early Jewish context, including Ecclesiastes and other Jewish Second Temple works, rabbinic midrashic and talmudic literature, and reflections of Jewish thought in early Christian and patristic writings. Contributors are: Tali Artman, Geoffrey Herman, Reuven Kiperwasser, Serge Ruzer, Cana Werman, and Carsten Wilke.

R2,634 Discovery Miles 26 340 Ships in 12 - 19 working days

This volume presents the preliminary results of the work carried out by the interdisciplinary cultural techniques research lab at the University of Erfurt. Taking up an impulse from media studies, its contributions examine -from a variety of disciplinary perspectives-the interplay between the formative processes of knowledge and action outlined within the conceptual framework of cultural techniques. Case studies in the fields of history, literary (and media) studies, and the history of science reconstruct seemingly fundamental demarcations such as nature and culture, the human and the nonhuman, and materiality and the symbolical order as the result of concrete practices and operations. These studies reveal that particularly basic operations of spatialization form the very conditions that determine emergence within any cultural order. Ranging from manual and philological "paper work" to practices of opening up and closing off spaces and collective techniques of assembly, these case studies replace the grand narratives of cultural history focusing on micrological examinations of specific constellations between human and nonhuman actors.

It is a fact that today's British stages resound with powerfully innovative voices and that, very often, these voices have been those of young women playwrights. This collection of essays gives visibility and pride of place to these fascinating voices by exploring the vitality, inventiveness and particularly strong relevance of these poetics. These women playwrights sometimes invent radically new forms and sometimes experiment with conventional ones in fresh and unexpected ways, as for example when they re-energize naturalism and provide it with new missions. The plays that are addressed are all concerned with the necessity to grasp the complexity of the contemporary world and to further investigate what it means to be human. Intimate or epic, and sometimes both at once, visionary or closer to everyday life, these plays approach the contemporary world through a multitude of prisms - historical, scientific, political and poetic - and open different and visionary perspectives.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 107.Bedrock river channels are sites of primary erosion in the landscape, fixing the baselevel for all points upstream. This volume provides for the first time an integrated view of the characteristics and operation of this important, though hitherto neglected, class of channels. Examples are provided from several continents and cover a wide range of spatial scales from the large river basins (such as the Colorado River in the United States and the Indus River in Pakistan) down to reach scales and individual sites. Likewise the geologic timescales considered range from erosion and transportation during individual flows to accumulated effects over periods of tens of millions of years.

In this latest work by the prominent historian, Deloria turns his audacious intellect and fiery indignation to an examination of modern science as it relates to Native American oral history and exposes the myth of scientific fact, defending Indian mythology as the more truthful account of the history of the earth. Deloria grew up in South Dakota, in a small border town on the Pine Ridge Indian Reservation. There he was in a position to absorb the culture and traditions of Western Europeans, as well as of the native Sioux people. Much of the formal education he received about science, including how the earth and its people had formed and developed over time, came from the white, Western world; he and his fellow students accepted it as gospel, even though this information often contradicted the ancient teachings of the Native American peoples. As an adult, though, Deloria saw how some of these scientific "facts", once readily accepted as the truth, now began to run against common sense as well as the teachings of his people. For example, the question of why certain peoples had lighter or darker skins posed an especially thorny problem - one that mainstream journals and books failed to answer in a way that was satisfactory to this budding skeptic. When he began to reexamine other previously irrefutable theories - of the earth's creation, of the evolution of people, of the acceptance of the notion that the Indians themselves had been responsible for slaughtering and wiping out certain large animals from their habitat over time - he also began to reconsider the value of myth and religion in an explanation of the world's history and, in the process, to document and record traditionalknowledge of Indian tribes as offered by the tribal elders.

EMERGENT EVOLUTION- THE GIFFORD LECTURES DELIVERED IN THE UNIVERSITY OF ST. ANDREWS IN THE YEAR 1922 by C. LLOYD MORGAN. Originally published in 1923. PREFACE: HALF a century ago, as years run, a student was called on to take the chair at a dinner in connection with the Royal School of Mines. Members of the staff were present. And the fortunate youth was honoured by the support of Professor Huxley. Which of the lines of science you have followed has chiefly engaged your interest Following up the thread of my reply, he drew from me the confession that an interest in philosophy, and in the general scheme of things, lay deeper than my interest in the practical applications of science to what then purported to be my bread-and butter training. With sympathetic kindliness that soon dispelled my fear of him he led me to speak more freely, to tell him how this came about, what J had read, and so on. That such a man should care to know what Berkeley and Hume had done for me what I had got from Descartes Discourse how I was just then embrangled in difficulties over Spinoza filled me with glad surprise. His comments were so ripe and they were made to help me Whatever else you may do, he said, keep that light burning. But remember that biology has supplied a new and powerful illuminant. Then speeches began. His parting words were When you have reached the goal of your course, why not come and spend a year with us at South Kensington So when I had gained the diploma of which so little direct use was to be made, and when my need of the illuminant, and my lack of intimate acquaintance with the facts on which the new lamp shed light, had been duly impressed on me during a visit to North America andBrazil, I followed his advice, attended his lectures, and worked in his laboratory. On one of the memorable occasions when he beckoned me to come to his private room he spoke of St. George Mivart s Genesis of Species. I had asked him some questions thereon a few days before to which he was then too busy to reply and he gave me this opportunity of repeating them. Mivart had said If then such innate powers must be attributed to chemical atoms, to mineral species, to gemmules, and to physiological units, it is only reasonable to attribute such to each individual organism p. 260, I asked on what grounds this line of approach was unreasonable for even then there was lurking within me some touch of Pelagian heresy in matters evolutionary. Far from snub bing a youthful heretic he dealt kindly with him. The question, he said, was open to discussion but he thought Mivarts position was based on considerations other than scientific. Any analogy between the growth of a crystal and the development of an organism was of very doubtful validity. Yes, Sir 1 I said, save in this that both invite us to distinguish between an internal factor and the incidence of external conditions He then asked what I under stood by innate powers, saying that for Mivart they were the substantial forms of scholastic tradition. I ventured to suggest that the School men and their modern disciples were trying to explain what men of science must perhaps just accept on the evidence. And I asked whether for an innate power in the organism one might substitute what he had taught us to call an internal metamorphic tendency which must be as distinctly recognised as that of an internal conservative tendency H. E. ii. p. 116. Ofcourse you may so long as you regard this merely as an ex pression of certain facts at present unexplained. n I then asked whether it was in this sense one should accept his statement that nature does make leaps ii. pp. 77, 97 and, if this were so, whether the difference on which Mivart laid so much stress that between the mental capacities of animals and of men might not be regarded as a natural leap in evolutionary progress. This was the point to which I was leading up...

"A Handbook of Tricuspid And Pulmonary Valve Disease" contains a detailed description of the diseases of these two valves. A detailed description of Ebstein's Anomaly Of Tricuspid vale is highlight of this book. Etiology, pathogenesis and hemodynamics of diseases of both valves have been dealt in simple and comprehensible manner. Special effort has been made to explain the clinical features (Symptoms and signs) of disease. Probably the clinical features is the forgotten art in the newer text books. However, the author has taken a special interest to include a detailed description of clinical features. The treatment section includes description about the various interventions (catheter based as well as surgical) and it also includes the ACC / AHA guidelines. Like his previous two handbooks (A handbook of Rheumatic Fever and A Handbook of Aortic valve Disease), this book also has extensive description of all aspects of the disease. A small chapter about 'Straight Back Syndrome' has also been included in this book. All in all, the book promises to be a great reference book for Aortic Valve disease and is worth having it on shelf for easy reading. The point wise and concise writing has made this book specially useful for students and exam going students

This book examines two mid-nineteenth century thinkers - the Austrian writer Adalbert Stifter and the French architect Eugene E. Viollet-le-Duc - who imagined cultural history on the model of earth history: as a history of objects to be restored and worlds to be reconstructed. The nascent field of geology shaped cultural thought; their conservationism, informed by erosion, envisions a future of restorative renewal.

In Things That Make Us Smart, Donald A. Norman explores the complex interaction between human thought and the technology it creates, arguing for the development of machines that fit our minds, rather than minds that must conform to the machine.Humans have always worked with objects to extend our cognitive powers, from counting on our fingers to designing massive supercomputers. But advanced technology does more than merely assist with thought and memory,the machines we create begin to shape how we think and, at times, even what we value. Norman, in exploring this complex relationship between humans and machines, gives us the first steps towards demanding a person-centreed redesign of the machines that surround our lives.
