The Emperor of All Maladies


Book Description

Winner of the Pulitzer Prize and a documentary from Ken Burns on PBS, this New York Times bestseller is “an extraordinary achievement” (The New Yorker)—a magnificent, profoundly humane “biography” of cancer—from its first documented appearances thousands of years ago through the epic battles in the twentieth century to cure, control, and conquer it to a radical new understanding of its essence. Physician, researcher, and award-winning science writer, Siddhartha Mukherjee examines cancer with a cellular biologist’s precision, a historian’s perspective, and a biographer’s passion. The result is an astonishingly lucid and eloquent chronicle of a disease humans have lived with—and perished from—for more than five thousand years. The story of cancer is a story of human ingenuity, resilience, and perseverance, but also of hubris, paternalism, and misperception. Mukherjee recounts centuries of discoveries, setbacks, victories, and deaths, told through the eyes of his predecessors and peers, training their wits against an infinitely resourceful adversary that, just three decades ago, was thought to be easily vanquished in an all-out “war against cancer.” The book reads like a literary thriller with cancer as the protagonist. Riveting, urgent, and surprising, The Emperor of All Maladies provides a fascinating glimpse into the future of cancer treatments. It is an illuminating book that provides hope and clarity to those seeking to demystify cancer.




Solvent Extraction


Book Description

The main challenge in modern solvent extraction separation is that most techniques are mainly empirical, specific and particular for narrow fields of practice and require a large degree of experimentation. This concise and modern book provides a complete overview of both solvent extraction separation techniques and the novel and unified competitive complexation/solvation theory. This novel and unified technique presented in the book provides a key for a preliminary quantitative prediction of suitable extraction systems without experimentation, thus saving researchers time and resources. Analyzes and compares both classical and new competitive models and techniques Offers a novel and unified competitive complexation / solvation theory that permits researchers to standardize some parameters, which decreases the need for experimentation at R&D Presents examples of applications in multiple disciplines such as chemical, biochemical, radiochemical, pharmaceutical and analytical separation Written by an outstanding scientist who is prolific in the field of separation science

Honky


Book Description

This vivid memoir captures how race, class, and privilege shaped a white boy’s coming of age in 1970s New York—now with a new epilogue. “I am not your typical middle-class white male,” begins Dalton Conley’s Honky, an intensely engaging memoir of growing up amid predominantly African American and Latino housing projects on New York’s Lower East Side. In narrating these sharply observed memories, from his little sister’s burning desire for cornrows to the shooting of a close childhood friend, Conley shows how race and class inextricably shaped his life—as well as the lives of his schoolmates and neighbors. In a new afterword, Conley, now a well-established senior sociologist, provides an update on what his informants’ respective trajectories tell us about race and class in the city. He further reflects on how urban areas have (and haven’t) changed over the past few decades, including the stubborn resilience of poverty in New York. At once a gripping coming-of-age story and a brilliant case study illuminating broader inequalities in American society, Honky guides us to a deeper understanding of the cultural capital of whiteness, the social construction of race, and the intricacies of upward mobility.




Flame-Retardant Polymeric Materials


Book Description

Flammability has been recognized as an increasingly important social and scientific problem. Fire statistics in the United States (Report of the National Commission on Fire Prevention and Control. "America Burning:' 1973) emphasized the vast devastation to life and property--12.000 lives lost annually due to fire. and these deaths are usually caused by inhaling smoke or toxic gases: 300.000 fire injuries: 11.4 billion dollars in fire cost at which 2.7 billion dollars is related to property loss: a billion dollars to burn injury treatment: and 3.3 billion dollars in productivity loss. It is obvious that much human and economic misery can be attributed to fire situations. In relation to this. polymer flammability has been recognized as an in creasingly important social and scientific problem. The development of flame-retardant polymeric materials is a current example where the initia tive for major scientific and technological developments is motivated by sociological pressure and legislation. This is part of the important trend toward a safer environment and sets a pattern for future example. Flame retardancy deals with our basic everyday life situations-housing. work areas. transportation. clothing and so forth-the "macroenvironment" capsule within which "homosapiens" live. As a result. flame-retardant polymers are now emerging as a specific class of materials leading to new and diversified scientific and technological ventures.




Principles of Food Sanitation


Book Description

Large volume food processing and preparation operations have increased the need for improved sanitary practices from processing to consumption. This trend presents a challenge to every employee in the food processing and food prepara tion industry. Sanitation is an applied science for the attainment of hygienic conditions. Because of increased emphasis on food safety, sanitation is receiving increased attention from those in the food industry. Traditionally, inexperienced employees with few skills who have received little or no training have been delegated sanitation duties. Yet sanitation employees require intensive training. In the past, these employees, including sanitation program managers, have had only limited access to material on this subject. Technical information has been confined primarily to a limited number of training manuals provided by regulatory agen cies, industry and association manuals, and recommendations from equipment and cleaning compound firms. Most of this material lacks specific information related to the selection of appropriate cleaning methods, equipment, compounds, and sanitizers for maintaining hygienic conditions in food processing and prepara tion facilities. The purpose of this text is to provide sanitation information needed to ensure hygienic practices. Sanitation is a broad subject; thus, principles related to con tamination, cleaning compounds, sanitizers, and cleaning equipment, and specific directions for applying these principles to attain hygienic conditions in food processing and food preparation are discussed. The discussion starts with the importance of sanitation and also includes regulatory requirements and voluntary sanitation programs including additional and updated information on Hazard Analysis Critical Control Points (HACCP).




An Idealist View Of Life


Book Description

One of the most profoundly religious books of our time - The Spectator Science is a system of second causes, which cannot describe the world adequately, much less account for it. In this remarkable treatise, Radhakrishnan explores aspects of the modern intellectual debate on science vis-a-vis religion and the vain attempts to find a substitute for religion. He discusses, drawing upon the traditions of East and West, the nature and validity of religious experience.Finally, he creates a fine vision of mans evolution and the emergence of higher values. The range of subjects combined with the authors own faith, undogmatic and free of creed, makes this book a philosophical education in itself.




Public Health Significance of Urban Pests


Book Description

The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]




Marijuana and the Cannabinoids


Book Description

Although primarily used today as one of the most prevalent illicit leisure drugs, the use of Cannabis sativa L., commonly referred to as marijuana, for medicinal purposes has been reported for more than 5000 years. Marijuana use has been shown to create numerous health problems, and, consequently, the expanding use beyond medical purposes into recreational use (abuse) resulted in control of the drug through international treaties. Much research has been carried out over the past few decades following the identification of the chemical structure of THC in 1964. The purpose of Marijuana and the Cannabinoids is to present in a single volume the comprehensive knowledge and experience of renowned researchers and scientists. Each chapter is written independently by an expert in his/her field of endeavor, ranging from the botany, the constituents, the chemistry and pharmacokinetics, the effects and consequences of illicit use on the human body, to the therapeutic potential of the cannabinoids.
