  definition of concentrated in chemistry: How Tobacco Smoke Causes Disease United States. Public Health Service. Office of the Surgeon General, 2010 This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
  definition of concentrated in chemistry: Dissolved Gas Concentration in Water John Colt, 2012-01-17 Aquacultural, oceanographic, and fisheries engineering, as well as other disciplines, require gas solubility data to compute the equilibrium concentration. These calculations, for example, can affect the output of aquacultural production or assist in environmental consulting. Until now, published solubility information has not been available in a consistent and uniform manner in one location. This book presents solubility concentrations of major atmospheric gases (oxygen, nitrogen, argon, carbon dioxide), noble gases (helium, neon, krypton, xenon), and trace gases (hydrogen, methane, nitrous oxide) as a function of temperature, salinity, pressure, and gas composition in a variety of formats. Data, equations, and theory are explained so that the user is able to understand the calculations and problems. Furthermore, data and solubility information are presented in a range of units to make them accessible across disciplines. This book will help the reader to look at a problem from a quantitative viewpoint and better understand carbonate chemistry. Revised from the earlier edition to include more accurate carbon dioxide tables and separate sections on the solubility of noble gases, trace gases, and oxygen in brines to provide a single resource for gas solubility data. This book is essential for all students and practitioners working in aquatic fields. - A single source for highly accurate and comprehensive tables for gas solubility in aquatic systems - Information provided in tables, equations, and computer programmes - Theory is presented to better understand the equations and calculations

  definition of concentrated in chemistry: Drug-like Properties: Concepts, Structure Design and Methods Li Di, Edward H Kerns, 2010-07-26 Of the thousands of novel compounds that a drug discovery project team invents and that bind to the therapeutic target, typically only a fraction of these have sufficient ADME/Tox properties to become a drug product. Understanding ADME/Tox is critical for all drug researchers, owing to its increasing importance in advancing high quality candidates to clinical studies and the processes of drug discovery. If the properties are weak, the candidate will have a high risk of failure or be less desirable as a drug product. This book is a tool and resource for scientists engaged in, or preparing for, the selection and optimization process. The authors describe how properties affect in vivo pharmacological activity and impact in vitro assays. Individual drug-like properties are discussed from a practical point of view, such as solubility, permeability and metabolic stability, with regard to fundamental understanding, applications of property data in drug discovery and examples of structural modifications that have achieved improved property performance. The authors also review various methods for the screening (high throughput), diagnosis (medium throughput) and in-depth (low throughput) analysis of drug properties. - Serves as an essential working handbook aimed at scientists and students in medicinal chemistry - Provides practical, step-by-step guidance on property fundamentals, effects, structure-property relationships, and structure modification strategies - Discusses improvements in pharmacokinetics from a practical chemist's standpoint

  definition of concentrated in chemistry: The Darkness Beckons Martyn Farr, 2017-05 Martyn Farr¿s The Darkness Beckons charts the history and development of cave diving, from early underwater expeditions in France in the late nineteenth century, through to cutting-edge dives across the globe, where iron-willed individuals are pushing the limits of equipment and techniques in the pursuit of exploration. Cave diving is the natural evolution of caving, where cavers and open-water divers overcome the challenges of water-filled passages by using specialist breathing apparatus to explore further and deeper than ever before. The challenges are many ¿ distance, depth, temperature, visibility, rockfall and simple restriction in passage size ¿ together with the physical and mental demands placed on an individual in an environment where, despite meticulous preparation, equipment can malfunction and one cannot expect to be rescued if something goes wrong. Early cave dives were made using Standard Equipment diving suits, before `frogman¿ equipment was adopted by British and Italian divers in the 1940s. Around the same time, Jacques-Yves Cousteau and Émile Gagnan designed the compressed-air aqualung, the first scuba equipment. The development of breathing apparatus has continued, alongside solutions to evermore challenging projects, especially those at extreme depth. British cave divers, including the author, have been at the forefront of many developments, such as the explorations at Wookey Hole in the Mendips, Keld Head in the Yorkshire Dales and Pozo Azul in Spain. Cave diving today is a truly international endeavour, and Farr gives detailed and engaging accounts of developments in Europe, the Americas, Australia and New Zealand, Southern Africa and more. Farr introduces cave diving¿s pioneers and chronicles their achievements. Among a cast of many are the Britons Graham Balcombe and Mike Boon; the American Sheck Exley, who died while attempting to establish a new depth record in the Zacatón sinkhole in Mexico; and the outstanding German cave diver and equipment innovator Jochen Hasenmayer. The stories of their adventures are charged with courage, danger and excitement, and some have led to tragedy. First published in 1980, this 2017 edition of The Darkness Beckons has been fully revised and updated to reflect the latest developments. Featuring over 400 breathtaking photographs and illustrations, and with a foreword by renowned American cave diver and explorer Bill Stone, it is an inspirational read for anyone with an interest in exploration and adventure.
