Download or read book Modern Phytochemical Methods written by Nikolaus H. Fischer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains reviews which are based on a symposium, given th at the 30 meeting of The Phytochemical Society of North America, held at Laval University in Quebec City, Canada on August 11-15, 1990. During the past two decades, there have been major new developments in methods which can be applied toward the isolation, separation and structure determination of complex natural products. Therefore, the topic of this symposium, "Modem Phytochemical Methods", is a very timely one. The organizers of the symposium recognized that it would not be possible to cover in detail all new advances in phytochemical methodology. It was therefore decided to emphasize general reviews on recent developments of major separation techniques such as high performance liquid chromatography as well as supercritical fluid chromato graphy. In addition, advances in commonly used structure determination methods, mainly NMR and MS, are reviewed. Other topics include methodo logies of micro-sampling for isolation and analysis of trichome constituents as well as recent breakthroughs on biosynthetic studies of monoterpenes using "enriched" basal cells of trichomes. The volume concludes with a review of quantitative structure-activity relationship (QSAR) studies of biologically active natural products. In Chapter I, K. Hostettmann and his colleagues give a general review of recent developments in the separation of natural products with major emphasis on preparative separations of biologically active plant constituents. The authors present a comparison of droplet countercurrent chromatography (OCCC) with the highly rapid and more versatile centrifugal partition chromatography (CPC).

Download or read book Corrosion of Magnesium Alloys written by G L Song and published by Woodhead Publishing. This book was released on 2011-03-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of magnesium alloys is increasing in a range of applications, and their popularity is growing wherever lightweight materials are needed. This book provides a comprehensive account of the corrosion of magnesium alloys. It covers not only the corrosion performances and mechanisms of Mg alloys in conventional environments, such as sodium chloride solutions, but also looks at their corrosion behaviours in special media, like engine coolants and simulated body fluids. Part one covers fundamentals such as the corrosion electrochemistry, activity and passivity of magnesium and its alloys. Part two then considers the metallurgical effect in relation to the corrosion of magnesium alloys, including the role of micro-structure and earth-rare elements, the corrosion behaviour of magnesium-based bulk metallic glasses, and the corrosion of innovative magnesium alloys. Part three goes on to describe environmental influences on the corrosion of magnesium alloys, such as atmospheric corrosion, stress corrosion cracking, creep and fatigue behaviour, and galvanic corrosion. Finally, part four is concerned with various means of protecting magnesium alloys against corrosion through the use of aluminium electrodeposition, conversion and electrophoretic coatings, and anodisation. With its distinguished editor and team of contributors, this book is an invaluable resource for metallurgists, engineers and designers working with magnesium and its alloys, as well as professionals in the aerospace and automotive industries.

This book was released on 2012-12-06 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical relaxation spectrometry involves the application of several different relaxation techniques to investigate the kinetics and mechanisms of fast chemical reactions and also dynamic molecul 10 ar processes that occur in liquids in the time range 1 - 10- secs. These methods have been used widely in several disciplines of the natural sciences including molecular biology, biochemistry, organic stereochemistry, detergent chemistry and inorganic chemistry. The purpose of the Advanced Study Institute was to provide a forum for scientists to discuss the role, scope and limitations of the various applications of chemical relaxation methods in order to stimulate discussion and interaction between workers in these different fields. The papers described in this volume are a summary of the contributions that were discussed at the meeting. The brief given to the authors was to attempt to prepare an article contain ing a good supply of references so that the book can be used not only by those starting in the field, but also by the specialist and research worker. These contributions cover a varied range of topics summarizing the achievements, the current state of knowledge and possible application in many disciplines. It is to be hoped that this volume will help to point out some new directions towards which research efforts are required and to attract new researchers with fresh points of view.

Download or read book The Human Advantage written by Suzana Herculano-Houzel and published by MIT Press. This book was released on 2016-03-18 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why our human brains are awesome, and how we left our cousins, the great apes, behind: a tale of neurons and calories, and cooking. Humans are awesome. Our brains are gigantic, seven times larger than they should be for the size of our bodies. The human brain uses 25% of all the energy the body requires each day. And it became enormous in a very short amount of time in evolution, allowing us to leave our cousins, the great apes, behind. So the human brain is special, right? Wrong, according to Suzana Herculano-Houzel. Humans have developed cognitive abilities that outstrip those of all other animals, but not because we are evolutionary outliers. The human brain was not singled out to become amazing in its own exclusive way, and it never stopped being a primate brain. If we are not an exception to the rules of evolution, then what is the source of the human advantage? Herculano-Houzel shows that it is not the size of our brain that matters but the fact that we have more neurons in the cerebral cortex than any other animal, thanks to our ancestors' invention, some 1.5 million years ago, of a more efficient way to obtain calories: cooking. Because we are primates, ingesting more calories in less time made possible the rapid acquisition of a huge number of neurons in the still fairly small cerebral cortex—the part of the brain responsible for finding patterns, reasoning, developing technology, and passing it on through culture. Herculano-Houzel shows us how she came to these conclusions—making “brain soup” to determine the number of neurons in the brain, for example, and bringing animal brains in a suitcase through customs. The Human Advantage is an engaging and original look at how we became remarkable without ever being special.

Download or read book Magnesium Alloys written by Alano Riley and published by . This book was released on 2016-08-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallic materials continue to play an essential role as biomaterials to assist with the repair or replacement of bone tissue that has become diseased or damaged. Metals are more suitable for load-bearing applications compared with ceramics or polymeric materials due to their combination of high mechanical strength and fracture toughness. Currently approved and commonly used metallic biomaterials include stainless steels, titanium, and cobalt-chromium-based alloys. A limitation of these current metallic biomaterials is the possible release of toxic metallic ions and/or particles through corrosion or wear processes that lead to inflammatory cascades which reduce biocompatibility and cause tissue loss. A resistance of magnesium alloys to surface degradation is paramount for their applications in automotive, aerospace, consumer electronics and general-purpose markets. The book places emphasis on oxidation, corrosion and surface modifications, designed to enhance the alloy surface stability. It covers a nature of oxides grown at elevated temperatures and oxidation characteristics of selected alloys in consort with elements of general and electrochemical corrosion. Medical applications are reflected that explore biocompatibility of magnesium alloys. Also techniques of surface modifications, designed to improve not only corrosion resistance but also corrosion fatigue, wear and other behaviors, are described. It will be a valuable resource for scientists and engineers from academia and industry. Magnesium is most commonly alloyed with other metals when being used in structural applications. Magnesium and its alloys which are chemically active can degrade naturally in the physiological environment by corrosion and are potential candidates in biodegradable hard-tissue implants. Magnesium alloys are mixtures of magnesium with other metals (called an alloy), often aluminum, zinc, manganese, silicon, copper, rare earths and zirconium. Magnesium is the lightest structural metal. Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys.

Available in PDF, EPUB and Kindle. Book excerpt: Distributed propulsion technology is one of the revolutionary candidates for future aircraft propulsion. In this book, which serves as the very first reference book on distributed propulsion technology, the potential role of distributed propulsion technology in future aviation is investigated. Following a historical journey that revisits distributed propulsion technology in unmanned air vehicles, commercial aircrafts, and military aircrafts, features of this specific technology are highlighted in synergy with an electric aircraft concept and a first-of-its-kind comparison between commercial and military aircrafts employing distributed propulsion arrangements. In light of propulsionairframe integration and complementary technologies, such as boundary layer ingestion, thrust vectoring and circulation control, transpired opportunities and challenges are addressed in addition to a number of identified research directions proposed for future aircrafts. Moreover, a diverse set of distributed propulsion arrangements are considered. These include: small engines, gas-driven multi-fan architectures, turboelectric systems featuring superconductive and non-superconducting electrical machine technology, and electromagnetic fans. This book features contributions by the National Aeronautics and Space Administration (NASA) and the United States Air Force (USAF), and includes the first proposed official definition for distributed propulsion technology in subsonic fixed wing aircrafts.

Download or read book Cognitive and affective control written by Gilles Pourtois and published by Frontiers E-books. This book was released on with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, cognition and emotion are seen as separate domains that are independent at best and in competition at worst. The French scientist and philosopher Blaise Pascal (1623-1662) famously said “Le coeur a ses raisons que la raison ne connaît point” (The heart has its reasons that reason does not know). Over the last century, however, psychologists and neuroscientists have increasingly appreciated their very strong reciprocal connections and interactions. Initially this was demonstrated in cognitive functions such as attention, learning and memory, and decision making. For instance, an emotional stimulus captures attention (e.g., Anderson & Phelps, 2001). Likewise, emotional stimuli are better learned and remembered than neutral ones (e.g., McGaugh, 1990) and they can provide strong incentives to bias decision making (Bechara et al., 1997). In more recent years, cognitive control has also been found to be intimately intertwined with emotion. This is consistent with an approach that considers cognitive control as an adaptive learning process (Braver & Cohen, 1999), reinforcement learning in particular (Holroyd & Coles, 2002; Verguts & Notebaert, 2009). From this perspective, cognitive control is not a cool encapsulated executive function, but instead involves rapidly calculating the value of situational, contextual, and action cues (Rushworth & Behrens, 2008) for the purpose of adapting the cognitive system toward future optimal performance. A wide array of research has shed light on cognitive control and its interactions with affect or motivation. Behaviorally, important phenomena include how people respond to difficult stimuli (e.g., incongruent stimuli, task switches), negative feedback, or errors and how this influences subsequent task processing. Neurally, an important target structure has been the anterior cingulate cortex (ACC) and its connections to traditional “emotional” (e.g., amygdala) and “cognitive” areas (e.g., (pre)motor cortex, dorsolateral prefrontal cortex). ACC seems to play a predominant role in integrating distant effects from remote cognitive and emotion systems in order to guide and optimize behavior. The current special issue focuses on the bi-directional link between emotion and cognitive control. We invite studies that investigate the influence from emotion on cognitive control, or vice versa, the influence of cognitive control on emotion. Contributions can be of different types: We welcome empirical contributions (behavioral or neuroscientific) but also computational modeling, theory, or review papers. By bringing together researchers from the traditionally separated domains, we hope to further stimulate the crosstalk between emotion and cognitive control, and thus to deepen our understanding of both.
