International Symposium on Marine Natural Products
International Symposium on Marine Natural Products presents the developments in the chemistry of soft corals. This book provides information on several relevant topics, including the chemistry of sponges, metabolites, biomimetic synthesis, and aplysiatoxins. Organized into five chapters, this compilation of papers begins with an overview of the biogenetical origin, distribution, and biological significance of Alcyonaceans. This text then examines the constituents and structural features of marine sponges. Other chapters consider the biosynthetic pathways to several halogenated marine natural products, which are based on bromonium ion. This book discusses as well the apparent isomerization of the aplysiatoxins during chromatography. The final chapter deals with the natural product research on marine organisms found in Australia. This book is a valuable resource for marine scientists, oceanographers, biologists, marine pharmacologists, chemists, and research workers.
Sensors
This book contains a selection of papers presented at the First National Conference on Sensors held in Rome 15-17 February 2011. The conference highlighted state-of-the-art results from both theoretical and applied research in the field of sensors and related technologies. This book presents material in an interdisciplinary approach, covering many aspects of the disciplines related to sensors, including physics, chemistry, materials science, biology and applications. · Provides a selection of the best papers from the First Italian National Conference on Sensors; · Covers a broad range of topics relating to sensors and microsystems, including physics, chemistry, materials science, biology and applications; · Offers interdisciplinary coverage, aimed at defining a common ground for sensors beyond the specific differences among the different particular implementation of sensors.
Polymeric Systems as Antimicrobial or Antifouling Agents
The rapid increase in the emergence of antibiotic-resistant bacterial strains, combined with a dwindling rate of discovery of novel antibiotic molecules, has created an alarming issue worldwide. Although the occurrence of resistance in microbes is a natural process, the overuse of antibiotics is known to increase the rate of resistance evolution. Under antibiotic treatment, susceptible bacteria inevitably die, while resistant microorganisms proliferate under reduced competition. Therefore, the out-of-control use of antibiotics eliminates drug-susceptible species that would naturally limit the expansion of resistant species. In addition, the ability of many microbial species to grow as a biof...
Diatom Nanotechnology
Diatoms are single cell algae composed of silica. They represent one of the most outstanding natural materials with exceptional structural, mechanical, optical, photonic and chemical properties optimized through millions of years of evolution. The unique nano and micro silica structures of the material combined with its availability as a low cost mineral from diatomaceous earth are attractive for solving many of today's environmental, energy and health problems. Diatom Nanotechnology provides a comprehensive overview of the material and its uses. The first part of the book looks at the distinctive porous silica structure of diatoms, the mechanism of their formation and their properties. Indi...
Sensors and Microsystems
This book collects a number of papers presented at the 13th Italian Conference on Sensors and Microsystems. It provides a unique perspective on the research and development of sensors, microsystems and related technologies in Italy. Besides the scientific value of the papers, this book offers a unique source of data to analysts that intend to survey the Italian situation on sensors and microsystems.
Forensic Communication in Theory and Practice
This edited collection brings together, for the first time, contributions from different context-language situations on forensic communication, combining theoretical and methodological studies with professional and technical capabilities. In this sense, academic and applied researches in forensic communication represent the scientific starting point of this book, which particularly investigates forensic discourse analysis and transcription of oral data. It makes use of variety of different approaches, including institutional interactions, the analysis of voice, discourse devices, and transcription methods. The book will appeal primarily to scholars in sociolinguistics and neighbouring disciplines within the social sciences which are interested in language, discourse studies, speaker recognition, transcription and research into aspects of forensic communication in late modernity.
Progress in Phytochemistry
Progress in Phytochemistry, Volume 4 deals with developments in phytochemistry and covers topics ranging from the pathway of nitrogen assimilation in plants to the biochemistry of plant amines and functions of steroids in plants. The naturally occurring cyanogenic glycosides are also considered, along with transfer RNA and aminoacyl-transfer RNA synthetases from higher plants. This volume is comprised of eight chapters and begins with a discussion on the pathway of nitrogen assimilation in plants and the enzymes involved in the process, with particular reference to glutamate synthase. The reader is then introduced to advances in the biochemistry of plant amines; the naturally occurring cyanogenic glycosides; phenylalanine ammonia lyase; and natural products such as flavonoid sulfates and sesterterpenes. The final chapter focuses on steroid functions in plants, giving emphasis to sterols, steroidal sapogenins and alkaloids, pregnane derivatives, cardiac glycosides, and sex hormones. This book will be of interest to phytochemists as well as non-specialists who want to obtain a clear picture of the problems involved in phytochemistry.
