Available in PDF, EPUB and Kindle. Book excerpt: The Role of Selenium in Nutrition reviews the most pertinent scientific literature dealing with the basic aspects of the present understanding of the roles of selenium (Se) in nutrition and health. The book begins with a general discussion of Se, covering its various forms, chemistry and physical properties, and techniques for Se analysis. This is followed by separate chapters on the environmental aspects of Se, including its presence in mineral deposits, soils, water, air, and uptake by plants; Se contents of human foods and animal feedstuffs; biological utilization of dietary Se; and absorption, excretion, metabolism, and tissue concentrations of Se. Subsequent chapters deal with the biochemical functions of Se; Se-related diseases of animals and livestock; the role of Se in human health and in support of normal immune function and disease resistance; and the relationship of Se and cancer. The final chapter reviews the evidence concerning the toxicity of Se compounds and sets this in perspective with current knowledge of the roles of Se in nutrition and health, and of the normal exposures of animals and humans to Se compounds.

Available in PDF, EPUB and Kindle. Book excerpt: The Physics of Selenium and Tellurium contains the proceedings of the International Symposium on the Physics of Selenium and Tellurium held in Montreal, Canada, on October 12-13, 1967 and sponsored by the Selenium-Tellurium Development Association, Inc. The papers explore the physics of selenium and tellurium, with emphasis on band structure, crystal growth and characterization, optical properties, and electrical properties. This book consists of 33 chapters and opens with a review of progress in the physics of selenium and tellurium, particularly with respect to the mechanical and thermal properties of trigonal selenium and tellurium and their lattice dynamics. The following chapters focus on calculations of the band structure of selenium and tellurium; magnetoabsorption in tellurium; trapping levels in hexagonal selenium; and coordination and thermal motion in crystalline selenium and tellurium. Infrared-active lattice vibrations in amorphous selenium and the contribution of lattice vibrations to the optical constants of tellurium are also discussed. This monograph will be a useful resource for physicists.

Available in PDF, EPUB and Kindle. Book excerpt: In July, 1988, more than 300 scientists from 29 different countries gathered at Tiibingen, W. Germany, in order to spend 4 days discussing their favourite trace element, selenium. This meeting continued the good tradition of three previous meetings held in Corvallis/Oregon, 1976, in Lubbock/Texas, 1980, and in Beijing/China, in 1984. Incidentally, the University of Tiibingen provided a unique historical background for a Symposium devoted to recent advances in biochemistry, pharmacology, human nutrition and human health; here, the first independent depart ment of Physiological Chemistry in Germany was founded in 1845. Pro fessor H9Ppe-Seyler elucidated here the hemin structure and his student Friedrich Miescher discovered the nucleic acids. This book contains one-half of the oral or poster presentations which were selected before the meeting was held on the basis of a one page abstract. It is the reader who will have to decide whether this time consuming policy of quality assessment was warranted or not.

Available in PDF, EPUB and Kindle. Book excerpt: The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

(Don’t Repeat Yourself) Approaches to software development in automated testing Discover the Selenium Grid Architecture and build your own grid for browser and mobile devices Use third party tools and services like ExtentReports for results processing, reporting, and SauceLabs for cloud-based test services Book Description The Selenium WebDriver 3.x Technology is an open source API available to test both Browser and Mobile applications. It is completely platform independent in that tests built for one browser or mobile device, will also work on all other browsers and mobile devices. Selenium supports all major development languages which allow it to be tied directly into the technology used to develop the applications. This guide will provide a step-by-step approach to designing and building a data-driven test framework using Selenium WebDriver, Java, and TestNG. The book starts off by introducing users to the Selenium Page Object Design Patterns and D.R.Y Approaches to Software Development. In doing so, it covers designing and building a Selenium WebDriver framework that supports both Browser and Mobile Devices. It will lead the user through a journey of architecting their own framework with a scalable driver class, Java utility classes, JSON Data Provider, Data-Driven Test Classes, and support for third party tools and plugins. Users will learn how to design and build a Selenium Grid from scratch to allow the framework to scale and support different browsers, mobile devices, versions, and platforms, and how they can leverage third party grids in the Cloud like SauceLabs. Other topics covered include designing abstract base and sub-classes, inheritance, dual-driver support, parallel testing, testing multi-branded applications, best practices for using locators, and data encapsulation. Finally, you will be presented with a sample fully-functional framework to get them up and running with the Selenium WebDriver for browser testing. By the end of the book, you will be able to design your own automation testing framework and perform data-driven testing with Selenium WebDriver. What you will learn Design the Selenium Driver Class for local, remote, and third party grid support Build Page Object Classes using the Selenium Page Object Model Develop Data-Driven Test Classes using the TestNG framework Encapsulate Data using the JSON Protocol Build a Selenium Grid for RemoteWebDriver Testing Construct Utility Classes for use in Synchronization, File I/O, Reporting and Test Listener Classes Run the sample framework and see the benefits of a live data-driven framework in real-time Who this book is for This book is intended for software quality assurance/testing professionals, software project managers, or software developers with prior experience in using Selenium and Java to test web-based applications.This book is geared towards the quality assurance and development professionals responsible for designing and building enterprise-based testing frameworks.The user should have a working knowledge of the Java, TestNG, and Selenium technologies
