Download or read book Water Extraction of Bioactive Compounds written by Herminia Dominguez and published by Elsevier. This book was released on 2017-09-20 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Extraction of Bioactive Compounds: From Plants to Drug Development draws together the expert knowledge of researchers from around the world to outline the essential knowledge and techniques required to successfully extract bioactive compounds for further study. The book is a practical tool for medicinal chemists, biochemists, pharmaceutical scientists and academics working in the discovery and development of drugs from natural sources. The discovery and extraction of bioactive plant compounds from natural sources is of growing interest to drug developers, adding greater fuel to a simultaneous search for efficient, green technologies to support this. Particularly promising are aqueous based methods, as water is a cheap, safe and abundant solvent. Water Extraction of Bioactive Compounds: From Plants to Drug Development is a detailed guide to the fundamental concepts and considerations needed to successfully undertake such processes, supported by application examples and highlighting the most influential variables. Beginning with an introduction to plants as sources of drugs, the book highlights the need for a move towards both more rational and greener techniques in the field, and presents multiple innovative water-based strategies for the discovery and extraction of bioactive constituents of botanicals. A broad range of available techniques are reviewed, including conventional and pressurized hot water extraction techniques, intensified processes such as microwave-assisted, ultrasound-assisted processes, and enzyme assisted extraction, and processes using combined techniques. - Covers the theoretical background and range of techniques available to researchers, helping them to select the most appropriate extraction method for their needs - Presents up-to-date and cutting edge applications by international experts - Highlights current use and future potential for industrial scale applications - Offers a thorough introduction to plants as sources of drugs, highlighting strategies for the discovery of novel bioactive constituents of botanicals

Download or read book Analysis of Seawater written by Crompton and published by Elsevier. This book was released on 2012-12-02 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of Seawater deals with the investigation of the micro-constituents in seawater in terms of nutrient content and environmental concerns. The book describes sampling, determination of anions, analysis of dissolved gases, and metal preconcentration techniques. The book also deals with monitoring radioactive elements, the determination of seawater organics, organometallic compounds, and the oxygen-demand parameters in seawater. It describes in detail surface and deep water sampling, the types of devices used, storage, preservation, and prevention of contamination during sample analysis. In examining dissolved gases, the investigator can use the amperometric titrimetric method (with some reservations) on chlorine, the ultraviolet method on ozone, electron capture gas chromatography on nitric oxide, and also the flow injection analysis on hydrogen sulphide. The methods for determining metals in seawater concern either for single element or for groups of elements. The investigator should always initiate various pre-concentration techniques when determining metals due to their low concentration and occurrence in seawater. The investigator uses various methods to determine different radioactive compounds such as uranium, polonium, thorium, radium, barium, radon, plutonium, strontium-90, and cesium-137. The book can be beneficial for meteorologists, environmentalists, marine ecologists, biologists, oceanographers, fisheries experts, for students studying hydrology, meteorology, as well as for river and lake authorities.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.

This book was released on 2014-06-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energy, Energy Information Administration (EIA) joined with the U.S. Department of the Interior, U.S. Geological Survey (USGS) to analyze the world uranium supply and demand balance. To evaluate short- term primary supply (0-15 years), the analysis focused on Reasonably Assured Resources (RAR), which are resources pro- jected with a high degree of geologic assurance and considered to be economically feasible to mine. Such resources include uranium resources from mines currently in production as well as resources that are in the stages of feasibility or of being permit- ted. Sources of secondary supply for uranium, such as stockpiles and reprocessed fuel, were also examined. To evaluate long- term primary supply, estimates of uranium from unconventional and from undiscovered resources were analyzed.
