Secondary Instabilities of Görtler Vortices in High-Speed Boundary Layers
by Jie RenThis thesis first reveals the mechanism of Görtler instabilities and then demonstrates how transitions at hypersonic flows can be effectively controlled (either promoted or suppressed) with Görtler or Klebanoff modes. It focuses on understanding and controlling flow transitions from mild laminar to fully turbulent flows at high speeds—aspects that have become crucial at the dawn of an incredible era, in which hypersonic vehicles are becoming available. Once this occurs, it will be possible to travel from Beijing to Los Angeles within just 2 hours, and we will all live in a genuinely global village—and not just virtually, but physically.Görtler instabilities have often been used to promote flow transition in hypersonic vehicles. However, how Görtler instabilities are excited and how they evolve in hypersonic flows are questions that have yet to be answered.

Secondary Metabolites Based Green Synthesis of Nanomaterials and Their Applications (Smart Nanomaterials Technology)
by Azamal HusenNanotechnology is gaining importance in every field of science and technology. Green synthesis of nanomaterials involves the use of microorganisms such as bacteria, fungi, viruses; and different lower and higher plants. Green synthesis of nanomaterials from plant extracts becoming popular in comparison to synthesis using microorganisms. Plant based-nanomaterials synthesis is easy, have no need to bring back from the culture medium, and is safe. Additionally, plant-based nanomaterials are eco-friendly, in comparison to physical and chemical modes of synthesis. Several lower and higher plants are rich in terms of secondary metabolites. These metabolites have been used as medicine in crude extract form or with some other formulations. They have been also used to isolate the bioactive compounds in modern medicine as well as in herbal medicine systems. Thus, phytochemicals present in the plant and their parts play an important role in nanomaterials synthesis, mainly due to the presence of a significant number of secondary metabolites, for instance, alkaloids, flavonoids, saponins, steroids, tannins, etc. Further, essential and aromatic oils have been also explored for nanomaterials synthesis, and they are also equally useful in terms of their various biological applications. These organic ingredients come from a wide range of plant components, such as leaves, stems, roots, shoots, flowers, bark, and seeds. Globally, the presence of different plants has shown a capability to produce huge and diverse groups of secondary metabolites. The functional groups present in the plant extract acts as capping and stabilizing agent. Most of the time, pure isolated bioactive compounds are more biologically active; hence scholars are focusing their research on the synthesis of nanomaterials using some particular class of secondary metabolites. Investigations have shown that the green synthesized nanomaterials were found to be more biologically active in comparison to chemically synthesized nanomaterials. These nanomaterials and or nanocomposites found different applications especially in drug delivery, detection and cure of cancer cells, diagnosis of a genetic disorder, photoimaging, and angiogenesis detection. They have also shown several applications in agricultural, horticultural as well as forestry sectors. The book in hand covers a wide range of topics as mentioned above. It incorporates chapters that the authors have skilfully crafted with clarity and precision, reviewing up-to-date literature with lucid illustrations. The book would cater to the need of graduate students as a textbook and simultaneously be useful for both novices and experienced scientists and or researchers working in the discipline of nanotechnology, nanomedicine, medicinal plants, plant science, economic botany, chemistry, biotechnology, pharmacognosy, pharmaceuticals, industrial chemistry, and many other interdisciplinary subjects. It should also inspire industrialists and policy makers associated with plant-based nano products.

Secondary Metabolites in Plant Stress Adaptation: Analytic Space of Secondary Metabolites (Signaling and Communication in Plants)
by Nabil SemmarThis book covers correlation and combined disciplinary aspects implying the use of secondary metabolites (SMs) of different plant species for control and monitoring of environment states. Phytochemical management of ecological systems represents an integrative field aiming for determination/evaluation of environment conditions from qualitative and quantitative analysis of plant metabolites. Plants respond to environmental conditions through productions of secondary metabolites. SMs represent highly variable and sensitive phytocompounds because of their small produced amounts, high structural variability and diversified activities. These characteristics make variations of SMs in plants to be highly informative on environmental conditions, physiological states and biological interactions. Qualitative and quantitative variations of SMs in plants are subject to correlation analyses to highlight links between biotic/abiotic conditions and plant chemical patterns.

Secondary Metabolites of Plant Growth Promoting Rhizomicroorganisms: Discovery and Applications
by Harikesh Bahadur Singh Chetan Keswani M. S. Reddy Estibaliz Sansinenea Carlos García-EstradaRecent changes in the pattern of agricultural practices from use of hazardous pesticides to natural (organic) cultivation has brought into focus the use of agriculturally important microorganisms for carrying out analogous functions. The reputation of plant growth promoting rhizomicroorganisms (PGPRs) is due to their antagonistic mechanisms against most of the fungal and bacterial phytopathogens. The biocontrol potential of agriculturally important microorganisms is mostly attributed to their bioactive secondary metabolites. However, low shelf life of many potential agriculturally important microorganisms impairs their use in agriculture and adoption by farmers. The focal theme of this book is to highlight the potential of employing biosynthesized secondary metabolites (SMs) from agriculturally important microorganisms for management of notorious phytopathogens, as a substitute of the currently available whole organism formulations and also as alternatives to hazardous synthetic pesticides. Accordingly, we have incorporated a comprehensive rundown of sections which particularly examine the SMs synthesized, secreted and induced by various agriculturally important microorganisms and their applications in agriculture. Section 1 includes discussion on biosynthesized antimicrobial secondary metabolites from fungal biocontrol agents. This section will cover the various issues such as development of formulation of secondary metabolites, genomic basis of metabolic diversity, metabolomic profiling of fungal biocontrol agents, novel classes of antimicrobial peptides. The section 1 will also cover the role of these secondary metabolites in antagonist-host interaction and application of biosynthesized antimicrobial secondary metabolites for management of plant diseases. Section 2 will discuss the biosynthesized secondary metabolites from bacterial PGPRs, strain dependent effects on plant metabolome profile, bio-prospecting various isolates of bacterial PGPRs for potential secondary metabolites and non-target effects of PGPR on microbial community structure and functions. Section 3 encompasses synthesis of antimicrobial secondary metabolites from beneficial endophytes, bio-prospecting medicinal and aromatic hosts and effect of endophytic SMs on plants under biotic and biotic stress conditions.
Secondary Schizophrenia
by Perminder S. Sachdev Matcheri S. KeshavanSchizophrenia may not be a single disease, but the result of a diverse set of related conditions. Modern neuroscience is beginning to reveal some of the genetic and environmental underpinnings of schizophrenia; however, an approach less well travelled is to examine the medical disorders that produce symptoms resembling schizophrenia. This book is the first major attempt to bring together the diseases that produce what has been termed 'secondary schizophrenia'. International experts from diverse backgrounds ask the questions: does this medical disorder, or drug, or condition cause psychosis? If yes, does it resemble schizophrenia? What mechanisms form the basis of this relationship? What implications does this understanding have for aetiology and treatment? The answers are a feast for clinicians and researchers of psychosis and schizophrenia. They mark the next step in trying to meet the most important challenge to modern neuroscience - understanding and conquering this most mysterious of human diseases.

Secrecy and Science: A Historical Sociology of Biological and Chemical Warfare
by Brian BalmerIt is no secret that twentieth-century Britain was governed through a culture of secrecy, and secrecy was particularly endemic in military research and defence policy surrounding biological and chemical warfare. More generally, it is hard to exaggerate the role of secrecy in all past biological and chemical warfare programmes and several recent historical surveys of biological and chemical warfare research have emphasised that all state sponsored programmes, together with sub-state organised activities, were cloaked in utmost secrecy. Of these research programmes, Britain carried out one of the most significant in scale and scope in the twentieth century. Yet, partly because of the secrecy surrounding the programme, there is still little academic literature on its historical development. Equally, and despite secrecy being a pervasive feature of past and contemporary societies, social scientists and historians have paid relatively little scholarly attention to the nature, mechanics and effects of secrecy, particularly with regard to secrecy in relation to the production and governance of science and technology. Drawing on classical sociological writing on secrecy by Simmel, Merton and Shils this groundbreaking book by Brian Balmer draws on recently declassified documents to investigate significant episodes in the history of biological and chemical warfare. At the same time, it draws on more contemporary perspectives in science and technology studies that understand knowledge and social order as co-produced within heterogeneous networks of 'things and people' in order to develop a theoretical set of arguments about how the relationship between secrecy and science might be understood.
Secret Agent 666: Aleister Crowley, British Intelligence and the Occult
by Richard B. SpenceAleister Crowley is best known today as a founding father of modern occultism. His wide, hypnotic eyes peer at us from the cover of The Beatles' Sgt. Pepper's Lonely Hearts Club Band, and his influence can be found everywhere in popular culture.Crowley, also known as the Great Beast, has been the subject of several biographies, some painting him as a misunderstood genius, others as a manipulative charlatan. None of them have looked seriously at his career as an agent of British Intelligence.Using documents gleaned from British, American, French, and Italian archives, Secret Agent 666 sensationally reveals that Crowley played a major role in the sinking of the Lusitania, a plot to overthrow the government of Spain, the thwarting of Irish and Indian nationalist conspiracies, and the 1941 flight of Rudolf Hess.Author Richard B. Spence argues that Crowley--in his own unconventional way--was a patriotic Englishman who endured years of public vilification in part to mask his role as a secret agent.The verification of the Great Beast's participation in the twentieth century's most astounding government plots will likely blow the minds of history buff s and occult aficionados alike.Author Richard B. Spence can be seen on various documentaries on the History Channel and is a consultant for Washington, DC's International Spy Museum. He is also the author of Trust No One: The Secret World of Sidney Reilly (Feral House).
Secret Agents
by Madeline DrexlerSo you think modern medicine has the whole virus game figured out? Think again. And it's not even a question of "if" we'll be hit by some new and deadly disease--it's "when."The war on germs is being fought on many fronts--from the skirmishes with disease-carrying mosquitoes that cross oceans hidden away in airline wheel wells to the high-profile battle against terrorists wielding deadly bioweapons. Today's bold headlines would have us believe that the biggest threat comes from bioterrorism. But don't underestimate Mother Nature, perhaps the most savage bioterrorist of all. Assisted by the increasing ease with which people--and the germs they carry--move across international borders, she's an effective force to be reckoned with, a key player on this battlefield. As author Madeline Drexler makes clear, we'd do best not to ignore her.Human beings and the pathogens that attack them are crossing paths more and more frequently, particularly as modern life grows increasingly complex. Whatever the infectious agent may be, whether it's pandemic flu, foodborne illness, a debilitating disease carried far and wide by biting insects, or some new microbial horror we have yet to detect, keen surveillance and rapid response are really the only weapons in our arsenal.Secret Agents looks at today's new and emerging infections--those that have increased in attack rate or geographic range, or threaten to do so--and tells the stories of scientists racing to catch up with invisible adversaries superior in both speed and guile. Each chapter focuses on a different threat: foodborne pathogens, antibiotic resistance, animals and insectborne diseases, pandemic influenza, infectious causes of chronic disease, and bioterrorism, including the latest information on the public health threats posed by anthrax and diseases such as smallpox.Based in part on material collected from the Forum on Emerging Infections hosted by the Institute of Medicine in Washington, D.C., Secret Agents is ultimately as engaging as it is disturbing. Drexler's thorough survey of the field of infectious disease, supplemented by extensive interviews with today's top researchers, yields a compelling portrait of a world engaged in a clandestine war.Emerging infections are among the many secret ties that bind the world into an organic whole. We know that infectious disease is an inescapable part of life, but we need to begin thinking globally and acting locally if we are to avoid the menace of a catastrophic outbreak of some new plague. Secret Agents sounds a clear and compelling call to take up arms against the organic predators among us.

Bringing them together here for the first time, Davis offers a new vision of the human body as a biological wonder of dizzying complexity and possibility.Written by an award-winning scientist at the forefront of this adventure, The Secret Body is a gripping drama of discovery and a landmark account of the dawning revolution in human health.
The Secret Capture: U-110 and the Enigma Story
by Stephen RoskillFor fifteen years after the end of the war all official Admiralty records showed the German submarine U 110 as sunk on 9 May 1941 by the surface escorts of convoy OB.318. As this book was the first to reveal, this was a deliberate deception, as the U-boat was actually captured and its contents fully investigated before being allowed to sink a day later, a fact skilfully kept from even the survivors of the submarines crew. As the official historian of the naval war, Roskill had followed the party line when writing his authorised account, but provoked by exaggerated claims concerning a US Navy capture of a U-boat in 1944, Roskill decided to set the record straight. His narrative is prefaced by brief coverage of previous submarine captures by the Royal Navy three Italian and one German before covering the U 110 operation in great detail, underlining the skill and bravery of those involved.We now know that the reason for the secrecy was that the U-boat gave up valuable codebooks, charts, ciphers and, most significantly, a complete and undamaged Enigma machine. At the time of the books first publication, Ultra was still a secret, so Roskill (who clearly knew about it) had to be discreet about the exact details of what was taken from the submarine while insisting on its crucial value to the war effort. However, a new introduction puts the capture into context, making clear its vital importance in the history of allied codebreaking in World War Two.
