Ambient ionization has emerged as one of the hottest and fastest growing topics in mass spectrometry enabling sample analysis with minimal sample preparation. Introducing the subject and explaining the basic concepts and terminology, this book will provide a comprehensive, unique treatise devoted to the subject. Written by acknowledged experts, there are full descriptions on how new ionization techniques work, with an overview of their strengths, weaknesses and applications. This title will bring the reader right up to date, with both applications and theory, and will be suitable as a tutorial text for those starting in the field from a variety of disciplines.
There is an increasing interest by consumers for high-quality food products with a clear geographical origin. With these products in demand, suitable analytical techniques are needed for the quality control. Current analytical approaches are mass spectrometry techniques, spectroscopic techniques, separation techniques, and others. Fingerprinting Techniques in Food Authentication and Traceability discusses the principles of the techniques together with their advantages and drawbacks, and reported applications concerning geographical authenticity. A combination of methods analyzing different types of food compounds seems to be the most promising approach to establish the geographical origin. The abundant acquired data are analyzed by chemometrics. Producing safe and high-quality food is a prerequisite to ensure consumer health and successful domestic and international trade, and is critical to the sustainable development of national agricultural resources. Systems to trace food or feed products through specified stages of production, processing, and distribution play a key role in assuring food safety. Analytical techniques that enable the provenance of food to be determined provide an independent means of verifying traceability systems and also help to prove product authenticity, to combat fraudulent practices and to control adulteration, which are important issues for economic, religious, or cultural reasons. Proof of provenance has become an important topic in the context of food safety, food quality, and consumer protection in accordance with national legislation and international standards and guidelines.
Mobile working and remote working from home or a small office, using phone, PC, fax and narrowband Internet is a rapidly increasing practice. The many well-documented benefits of working this way include higher productivity, more time spent with the family and local community and less time wasted commuting. At a community level they include benefits to the environment through substituting physical transport by telecommunications, and re-vitalisation of ruiral communities. Yet, people who work mainly this way face severe problems: a loss of contact with the office grapevine, the out of sight, out of mind syndrome, and exclusion from vital ad-hoc meetings and tutorials. Another major problem is slow speed of communication. This volume summarizes how technologies can revolutionise flexible working practices and go a long way towards solving the isolation problems of flexible workers.
This book and its sister volumes, i.e., LNCS vols. 3610, 3611, and 3612, are the proceedings of the 1st International Conference on Natural Computation (ICNC 2005), jointly held with the 2nd International Conference on Fuzzy Systems and Knowledge Discovery (FSKD 2005, LNAI vols. 3613 and 3614) from 27 to 29 August 2005 in Changsha, Hunan, China.
This issue discusses the concerns of skin disease in the United States and the national clinical dermatology research priorities – the article topics also closely follow the plan set out by the recent dermatology needs assessment of the UK. Articles include Health Care Disparities, The Burden of Skin Disease in the United States, as well as specific conditions such as psoriasis, acne, and melanoma. There is also an article devoted to dermatologic surgery needs assessment.
This Dictionary covers information and communication technology (ICT), including hardware and software; information networks, including the Internet and the World Wide Web; automatic control; and ICT-related computer-aided fields. The Dictionary also lists abbreviated names of relevant organizations, conferences, symposia and workshops. This reference is important for all practitioners and users in the areas mentioned above, and those who consult or write technical material. This Second Edition contains 10,000 new entries, for a total of 33,000.
The fifth edition of this widely used book by caregivers brings to you updated and revised content, built on the basic understanding that medicine does not work in a vacuum, but rather alongside other disciplines to provide the environment for a healthy and fulfilling long life. Edited by alumni and senior faculty at McGill University, with international contributions, this book advocates the achievement of better, longer, satisfying, and more productive lives for older persons. It is a helpful resource for physicians, professional caregivers, therapists, students, and residents in medical and nursing disciplines, who care for our burgeoning older population and need to know what to look for and when to consult specialists. Key Features: 1. Follows a uniform structure with many chapters having a hypothetical vignette for instructional purposes and with the clinical chapters detailing the features and diagnosis of given conditions, along with possible management protocols specific to afflicted older individuals. 2. Builds on the success of the previous four editions to provide high-quality content from international experts for physicians and other caregivers in the field. 3. Provides possible management for pressing problems, including the nursing home challenge, pandemics such as COVID, and precision therapy for cancer.
There is a dramatic rise of novel drug use due to the increased popularity of so-called designer drugs. These synthetic drugs can be illegal in some countries, but legal in others and novel compounds unknown to drug chemistry emerge monthly. This thoughtfully constructed edited reference presents the main chromatographic methodologies and strategies used to discover and analyze novel designer drugs contained in diverse biological materials. The methods are based on molecular characteristics of the drugs belonging to each individual class of compounds, so it will be clear how the current methods are adaptable to future new drugs that appear in the market.
