Esta obra reúne os maiores pesquisadores brasileiros da área para apresentarem seus temas de pesquisa, que estão construindo as bases de novas tecnologias e progressos inovadores.
This new Encyclopedia of Coastal Science stands as the latest authoritative source in the field of coastal studies, making it the standard reference work for specialists and the interested lay person. Unique in its interdisciplinary approach. This Encyclopedia features contributions by 245 well-known international specialists in their respective fields and is abundantly illustrated with line-drawings and photographs. Not only does this volume offer an extensive number of entries, it also includes various appendices, an illustrated glossary of coastal morphology and extensive bibliographic listings.
Pyrolysis is an irreversible thermochemical treatment process of materials at elevated temperatures in an inert atmosphere. It is basically a carbonisation process where an organic material is decomposed to produce a solid residue with high (or higher) carbon content and some volatile products. The decomposition reactions are accompanied in general with polymerisation and isomerisation reactions. The end products of pyrolysis can be controlled by optimizing pyrolysis parameters such as temperature and residence time. Pyrolysis is used heavily in the chemical industry to produce many forms of carbon and other chemicals from petroleum, coal, wood, oil shale, biomass or organic waste materials, and it is the basis of several methods for producing fuel from biomass. Pyrolysis also is the process of conversion of buried organic matter into fossil fuels.
This book includes recent advances in the use of clays in the design of medicinal products and medicinal devices. The pharmaceutical applications of nanoclays are far ranging, because of their distinct advantages: they are versatile (possess a wide range of mechanical, chemical and physical properties) and available at reasonable costs. Some special clays (mainly kaolinite, halloysite, montmorillonite, saponite, hectorite, palygorskite and sepiolite), as well as semi-synthetic (organoclays) or synthetic (double layer hydroxides) derivatives, are very useful materials for modulating drug delivery. In the last decade, several actives have been loaded onto nanoclays and similar inorganic excipi...
This book is designed to serve senior-level engineering students taking a capstone design course in fluid and thermal systems design. It is built from the ground up with the needs and interests of practicing engineers in mind; the emphasis is on practical applications. The book begins with a discussion of design methodology, including the process of bidding to obtain a project, and project management techniques. The text continues with an introductory overview of fluid thermal systems (a pump and pumping system, a household air conditioner, a baseboard heater, a water slide, and a vacuum cleaner are among the examples given), and a review of the properties of fluids and the equations of flui...
Fish lives in environments with a wide variety of chemical characteristics (fresh, brackish and seawater, acidic, alkaline, soft and hard waters). From an osmoregulatory point of view, fish have developed several mechanisms to live in these different environments. Fish osmoregulation has always attracted considerable attention and in the last years several studies have increased our knowledge of this physiological process. In this book several specialists have analyzed and reviewed the new data published regarding fish osmoregulation. The chapters present an integrative synthesis of the different aspects of this field focusing on osmoregulation in specific environments or situations, function of osmoregulatory organs, general mechanisms and endocrine control. In addition, interactions of osmoregulatory mechanisms with the immune system, diet and metabolism were also reviewed. New emerging techniques to study osmoregulation has also been analysed.
The field of food colloids is concerned with the structural and dynamic aspects of multi-phase food systems - dispersions, emulsions, foams, gels - viewed from a physical chemistry perspective as assemblies of molecules and particles in various states of organisation. The main molecular components of food colloids are proteins, lipids and polysaccharides. The primary objective of the field is to relate the structural, stability and rheological properties of such systems to the interactions between constituent components and to their distribution between the bulk phases and various kinds of interfaces. This volume records most of the lecture programme at the international conference on "Food Colloids - Proteins, Lipids and Polysaccharides" held in Sweden on 24-26th April 1996.
The main theme of this book is the exploration the underlying physical laws that permit the fabrication of nanometer-scale structures. As researchers attempt to fabricate nanometer-scale structures which do not exist per se, they must still employ the natural laws to fabricate them through processes such as self-assembly. This book will find service both as a reference work for researchers and as a comprehensive didactical text for graduate students.
"Stoddard has an impressive vision for composition ... each one seemingly marries fear and darkness with the delicacy of purity and the organic." -Juxtapoz This debut monograph from the Los Angeles-based photographer Alex Stoddard explores the parallels between metamorphosis in the natural world and human coming-of-age. Through staged, highly stylized images, Stoddard invites viewers into his magical, colorfully dark world of budding sexuality and crawling insects. Each detailed scene features a youthful subject--often Stoddard himself--in a state of change or paired with a many-legged counterpart. The previously unreleased series of 70 images paints a surreal picture of adolescence and youn...
