This new, self-contained volume covers in a critical, exhaustive, and in-depth manner the progress in AAS determinations of 55 chemical elements in 42 individual chapters, with an emphasis on the latest instrumental and methodological developments. These include Zeeman background correction, the Stabilized Temperature Platform Atomizer (STPA), flow-injection and continuous-flow approaches, slurry and solid sampling, efficient chemical modification, on-line sample pretreatment/enrichment, speciation, availability of QC materials, alternative analytical techniques, and more. A key to this vast application area is provided by well-organized tabulated information, including outlines of 782 selected AAS procedures for analysis of blood, serum, urine, hair, nail, teeth, tissues, food, and other relevant biological specimens. More than 2100 AAS papers are included in a unique bibliography of 3223 up-to-date references spanning the last 13 years.
The buzz is big for Douglas Florian’s new poetry collection about the unBEElieveably unique lives of honeybees—and the vital role they play in our ecosystem. Come inside the honeycomb—a busy, buzzy, bee-filled home—and learn about the unexpected wonders of these tiny insects’ lifestyles, families, and communities. In fourteen funny, fact-filled honeybee poems and paintings, Douglas Florian explores the natural history of these often-unappreciated critters, revealing them to be a totally cool—and totally important—part of our ecosystem. Indeed, these buzzy bugs have been in the spotlight lately as wild bee populations are dwindling, honey prices are rising, and beekeeping has become a popular hobby.
This Handbook focuses on the complex relationship between entrepreneurship and conflict. Editors Wim Naudé and Bernadette Power construct a broad overview of central research themes in the field, covering states being captured by entrepreneurs, states capturing businesses, entrepreneurship in post-conflict reconstruction, and entrepreneurs in conflict against other entrepreneurs.
'Sensors' is the first self-contained series to deal with the whole area of sensors. It describes general aspects, technical and physical fundamentals, construction, function, applications and developments of the various types of sensors. This is the first of two volumes focusing on chemical and biochemical sensors providing definitions, typical examples of chemical and biochemical sensors and historical remarks. It describes chemical sensor technologies and interdisciplinary tasks in the design of chemical sensors. The major part consists of a description of basic sensors. They include electrolyte sensors, solid electrolyte sensors, electronic conductivity and capacitance sensors, field effect sensors, calorimetric sensors, optochemical sensors, and mass sensitive sensors. This volume is an indispensable reference work for both specialists and newcomers, researchers and developers.
As discussed in this book, a large body of evidence indicates that selenium is a cancer chemopreventive agent. Further evidence points to a role of this element in reducing viral expression, in preventing heart disease, and other cardiovascular and muscle disorders, and in delaying the progression of AIDS in HIV infected patients. Selenium may also have a role in mammalian development, in male fertility, in immune function and in slowing the aging process. The mechanism by which selenium exerts its beneficial effects on health may be through selenium-containing proteins. Selenium is incorporated into protein as the amino acid selenocysteine. Selenocysteine utilizes a specific tRNA, a specific elongation factor, a specific set of signals, and the codeword, UGA, for its cotranslational insertion into protein. It is indeed the 21st naturally occurring amino acid to be incorporated into protein and marks the first and only expansion of the genetic code since the code was deciphered in the mid 1960s.
This volume constitutes the refereed proceedings of the 6th International Workshop on Adaptive Multimedia Retrieval, AMR 2008, held in Berlin, Germany, in June 2008.

Fundamentals of Analytical Chemistry are usually presented as a sum of chemical and physical foundations, laws, axioms and equations for analytical methods and procedures. In contrast, this book delivers a practice-oriented, general guiding theory valid for all methods and techniques. The metrological foundations included define strictly the figures of merit in order to minimize confusions still appearing in Analytical Chemistry publications today.
This volume LNCS 14252 constitutes the refereed proceedings of 25th International Conference on Information and Communications Security, ICICS 2023, held in Tianjin, China, during November 18–20, 2023. The 38 full papers presented together with 6 short papers were carefully reviewed and selected from 181 submissions. The conference focuses on: Symmetric-Key Cryptography; Public-Key Cryptography; Applied Cryptography; Authentication and Authorization; Privacy and Anonymity; Security and Privacy of AI; Blockchain and Cryptocurrencies; and System and Network Security.
