Testing Methods for Seed-transmitted Viruses: Principles and Protocols

by S. E. Albrechtsen

This practical guide covers the commonly used detection methods for seed-transmitted viruses and viroids that affect both tropical and temperate crops. It contains 25 complete step-by-step procedures for biological, serological and molecular techniques to detect and identify such viruses. Combining helpful practical notes with more detailed explanations of the principles behind the techniques, the book describes the general characteristics of seed-transmitted viral diseases and discusses outlines for the organization and interpretation of seed health assays. The techniques reviewed are also applicable to non-seed-transmitted viral agents.

Testing Molecular Wires

by Mateusz Wielopolski

The field of molecular electronics and organic photovoltaics is steadily growing. One of the major themes in molecular electronics is the construction, measurement, and understanding of the current-voltage response of an electronic circuit, in which molecules may act as conducting elements. The investigated molecular structures in this thesis have been shown to be suitable for distance-independent charge transport. More precisely, the systems investigated were of particular interest due to their ability to provide efficient electronic coupling between electroactive units, and display wire-like behavior in terms of transferring charges from donors to acceptors. Besides impacting on the field of molecular electronics, the results of this research also has applications in the design and development of light harvesting, photoconversion and catalytic modules. This work is a great asset to the field of charge transport through organic pi-conjugated molecules.

Testing Novel Water Oxidation Catalysts for Solar Fuels Production (PoliTO Springer Series)

by Carminna Ottone Simelys Hernández Marco Armandi Barbara Bonelli

This book offers comprehensive information on the main techniques for measuring water-oxidation-catalyst (WOC) performance, with a particular focus on the combined use of sacrificial oxidants and dyes within closed-batch reactors. It provides an overview of the latest advances in the synthesis of more efficient WOCs, followed by an analysis of the requirements for sustainable energy production. Readers will find a detailed description of the reaction mechanism used in catalyst assessment systems, which reveals the benefits and limitations of the most common sacrificial oxidant/dye pair. Experimental techniques including electrochemical methods for characterizing novel and non-photoactive WOCs are also described. Throughout the book, various manganese oxides are used as examples of the techniques reviewed or proposed systems. Cost considerations and technological perspectives of the scale-up of solar-driven hydrogen production are also addressed. Lastly, the book presents lessons learned from the implementation of a large-scale real-world device.

Testing Quantum Theory with Higher-Order Interference in Many-Particle Correlations (Springer Theses)

by Marc-Oliver Pleinert

The structure of quantum theory permits interference of indistinguishable paths. At the same time, however, it also limits such interference to certain orders and any higher-order interference is prohibited. This thesis develops and studies concepts to test quantum theory with higher-order interference using many-particle correlations, the latter being generally richer and typically more subtle than single-particle correlations. It is demonstrated that quantum theory in general allows for interference up to order 2M in M-particle correlations. Depending on the mutual coherence of the particles, however, the related interference hierarchy can terminate earlier. In this thesis, we show that mutually coherent particles can exhibit interference of the highest orders allowed. We further demonstrate that interference of mutually incoherent particles truncates already at order M+1, although interference of the latter is principally more multifaceted than their coherent counterpart. We introduce two families of many-particle Sorkin parameters, whose members are expected to be all zero when quantum mechanics holds. As proof of concept, we demonstrate the disparate vanishing of such higher-order interference terms as a function of coherence in experiments with mutually coherent and incoherent sources. Finally, we investigate the influence of exotic kinked or looped quantum paths, which are permitted by Feynman’s path integral approach, in such setups.

Testosterone Rex: Myths of Sex, Science, and Society

by Cordelia Fine

“Goodbye, beliefs in sex differences disguised as evolutionary facts. Welcome the dragon slayer: Cordelia Fine wittily but meticulously lays bare the irrational arguments that we use to justify gender politics.”—Uta Frith, emeritus professor of cognitive development, University College London Many people believe that, at its core, biological sex is a fundamental, diverging force in human development. According to this overly familiar story, differences between the sexes are shaped by past evolutionary pressures—women are more cautious and parenting-focused, while men seek status to attract more mates. In each succeeding generation, sex hormones and male and female brains are thought to continue to reinforce these unbreachable distinctions, making for entrenched inequalities in modern society. In Testosterone Rex, psychologist Cordelia Fine wittily explains why past and present sex roles are only serving suggestions for the future, revealing a much more dynamic situation through an entertaining and well-documented exploration of the latest research that draws on evolutionary science, psychology, neuroscience, endocrinology, and philosophy. She uses stories from daily life, scientific research, and common sense to break through the din of cultural assumptions. Testosterone, for instance, is not the potent hormonal essence of masculinity; the presumed, built-in preferences of each sex, from toys to financial risk taking, are turned on their heads. Moving beyond the old “nature versus nurture” debates, Testosterone Rex disproves ingrained myths and calls for a more equal society based on both sexes’ full, human potential.

Testosterone: An Unauthorized Biography

by Katrina Karkazis Rebecca M. Jordan-Young

Testosterone is neither the biological essence of manliness nor even the “male sex hormone.” It doesn’t predict competitiveness or aggressiveness, strength or sex drive. Rebecca Jordan-Young and Katrina Karkazis pry testosterone loose from more than a century of misconceptions that undermine science while making social fables seem scientific.

Testosterone: The Story of the Hormone that Dominates and Divides Us

by Carole Hooven

***'With all the talk about testosterone in sex, sports and politics, we need a good explanation of the science and its implications, and this one is outstanding.' STEVEN PINKER, bestselling author of The Blank Slate'Who knew that I would rejoice in being deeply immersed in testosterone? Fascinating, vital, unputdownable.' JULIE BINDEL'The definitive book on testosterone . . . A brave and significant book . . . simply fascinating and filled with extraordinary facts.' EVENING STANDARDThrough riveting personal stories and the latest research, Harvard evolutionary biologist Carole Hooven shows how testosterone drives the behaviour of the sexes apart and how understanding the science behind this hormone is empowering for all.The biological source of masculinity has inspired fascination, investigation and controversy since antiquity. From the eunuchs in the royal courts of ancient China to the booming market for 'elixirs' of youth in nineteenth-century Europe, humans have been obsessed with identifying and manipulating what we now know as testosterone. And the trend shows no signs of slowing down. Thanks to this history and the methods of modern science, today we have a rich body of research about testosterone's effects in both men and women. The science is clear: testosterone is a major, invisible player in our relationships, sex lives, athletic abilities, childhood play, gender transitions, parenting roles, violent crime, and so much more. But there is still a lot of pushback to the idea that it does, in fact, contribute to sex differences and significantly influence behaviour.Hooven argues that acknowledging testosterone as a potent force in society doesn't reinforce stifling gender norms or patriarchal values. Testosterone and evolution work together to produce a huge variety of human behaviour, and that includes a multitude of ways to be masculine and feminine. Understanding the science sheds light on how we work and relate to one another, how we express anger and love, and how we fight bias and problematic behaviour to build a fairer society.

Tetrad Formalism for Exact Cosmological Observables (SpringerBriefs in Physics)

by Ermis Mitsou Jaiyul Yoo

This book presents a novel mathematical formalism, based on the tetrad formulation of differential geometry, for describing cosmological observables exactly and conveniently. It covers all the standard observables, i.e. distances, weak lensing, number counts and cosmic microwave background, and also includes a detailed derivation of general-relativistic matrix kinetic theory. All the fully nonlinear equations are derived in detail and the mathematical content is self-contained, so that readers require only a basic knowledge of general relativity. Moreover, the authors discuss several subtle issues that are usually overlooked in the literature and, in particular, issues that distinguish this formalism from the more approximative standard practice.

Tetramer Stability and Functional Regulation of Tumor Suppressor Protein p53

by Rui Kamada

This thesis presents the first report of the comprehensive and quantitative analysis of the effects of tumor-derived mutations on the tetrameric structure of tumor suppressor protein p53, which plays a central role in maintaining genomic integrity. Inactivation of p53 via mutation of its gene is a key step in tumorigenesis. Biophysical analyses revealed that the stability of the mutant peptides varied widely. Formation of a tetrameric structure is to be critical for protein-protein interactions, DNA binding, and the post-translational modification of p53. A small destabilization of the tetrameric structure therefore could result in dysfunction of tumor suppressor activity. This work suggests that the threshold for loss of tumor suppressor activity, in terms of the disruption of p53's tetrameric structure, could be extremely low. Furthermore, functional control of p53 via tetramer formation was demonstrated, based on the structure-function analysis of mutant p53. The results disclosed that relatively small changes in tetramer formation, induced by the stabilization or inhibition of homo-tetramerization, could control p53 function.

The book summarises recent advances in the fields of biology in which the role of tetraspanins have been established and also covers the molecular evolution of the tetraspanin superfamily and structural aspects of the organisation of tetraspanin microdomains.

Tetsugaku Companion to Japanese Ethics and Technology (Tetsugaku Companions to Japanese Philosophy #1)

by Thomas Taro Lennerfors Kiyoshi Murata

This book explores the relevance of Japanese ethics for the field of ethics of technology. It covers the theories of Japanese ethicists such as Nishida Kitarō, Watsuji Tetsurō, Imamichi Tomonobu, Yuasa Yasuo, as well as more contemporary ethicists, and explores their relevance for the analysis of energy technologies, ICT, robots, and geoengineering. It features contributions from Japanese scholars, and international scholars who have applied Japanese ethics to problems in the global condition. Technological development is considered to cause new ethical issues, such as genetically modified organisms fostering monocultures, nanotechnologies causing issues of privacy, as well as health and environmental issues, robotics raising issues about the meaning of humanity, and the risks of nuclear power, as witnessed in the Fukushima disaster. At the same time, technology embodies a hope for mankind, such as ICT improving relationships between human beings and nature, and smart systems assisting humans in leading a more ethical and environmentally friendly life. This book explores these ethical issues and their impact from a Japanese perspective.

Teucrium Species: Biology and Applications

by Milan Stanković

Teucrium species are an intersting object of research in the various aspects of science with multiple applications. With more than 300 species, Teucrium is one of the largest and well distributed genera of the Lamiaceae family. Known medicinal Teucrium species have a long traditional use as well as different potential applications in pharmacy, food and beverage industry. Teucrium species are very rich in a variety of secondary metabolites with significant biological activities. Based on that, the book contains 15 chapters which discusses recent advances in exploring the unique features of Teucrium species including morphology, systematics, taxonomy, biogeography, ethnobotany, phytochemistry, biological activity such as genotoxic, antioxidant, antibacterial, antifungal, antiviral, anticancer, anticholinesterase, antidiabetic and anti-inflammatory activity of secondary metabolites as well as applications including current challenges and further perspectives. Some medicinal Teucrium species in excessive use can cause certain consequences. This phenomenon and precaution is also described. Whilst this book is primarily aimed at scientists, researchers, beginners in the investigations of Teucrium species, graduate and post-graduate students in biology, botany, biotechnology, agriculture, and pharmacy, as well as science enthusiasts and practitioners involved in medicinal plants applications. Book provides complete Teucrium species list, color photographs of selected Teucrium species on natural habitats, as well as up-to-date bibliography related to Teucrium genus.

Tewkesbury Walks

by Bernard Michaux

The book is composed of eight chapters, each of which are organised as walks around the Tewkesbury (UK) countryside, which move from the specific to increasingly broader ideas. So, the MS starts with an individual's relationship to their environment (Avon and Severn Valleys Loop) that leads to a description of conservation issues at local, national and international levels, and ultimately to a discussion of the importance of Citizen Science (Coombe Hill - Apperley -Deerhurst). The following chapter (Mythe Bridge - Forthampton - Tewkesbury) looks at science as it is actually practiced and its role in modern society by an analysis of the theory of Continental Drift and a biography of Alfred Wegener. This is a story that really deserves a much wider audience, as the idea was, in my opinion, as revolutionary as general relativity or quantum mechanics, and Wegener himself was such a heroic character. The following chapter (Tewkesbury Ham) also uses biography - this time of Alfred Russel Wallace - to investigate his ideas about how animal and plant distributions are inextricably linked to geological change. Wallace was every bit as heroic as Wegener, lived an even more adventurous life, and also deserves to be more widely known and appreciated. 2013 is the centenary of his death and he will be much in the news this year, so it would be timely to publish an account of his life and work suitable for the general public. The chapters on Wegener and Wallace set the scene for a detailed discussion of biogeography. This has been an active area of research for the past 30 years and I think it's about time that somebody wrote about what has been an intellectually exciting and profoundly significant development in our view of ourselves and the world we live in.

Texas Amphibians: A Field Guide

by Bob L. Tipton Terry L. Hibbitts Toby J. Hibbitts Troy D. Hibbitts Travis J. Laduc

With a wide variety of habitats ranging from southeastern swamps to western deserts, Texas is home to numerous species of frogs, toads, and salamanders. Each area of Texas has a particular set of species that has evolved there over thousands of years. Indeed, most amphibians are not very mobile, and many live their entire lives within a few square meters. This makes them particularly vulnerable to environmental degradation and habitat destruction. Texas Amphibians is the only field guide focused exclusively on the state's frogs, toads, and salamanders. It presents brief, general accounts of the two orders and fifteen families. Then it identifies each of the seventy-two species in detail, including size, description, voice (if applicable), similar species, distribution (with maps), natural history, reproduction, subspecies (if applicable), and comments and conservation information. Color photographs illustrate the species. The book also includes a general introduction to amphibian natural history, conservation, observation and collection, maintenance in captivity, museum and preserved specimens, and scientific and common names, as well as scientific keys to Texas salamanders and frogs and a generic key to amphibian larvae. This wealth of information, compiled by a team of experts who collectively have over a century of experience in field herpetology, will increase our appreciation for amphibians and the vital role they play as an early indicator of threats to the quality of the environment that we all share.

Texas Bobwhites

by Jon A. Larson

Northern bobwhites are one of the most popular game birds in the United States. In Texas alone, nearly 100,000 hunters take to the field each fall and winter to pursue wild bobwhite quail. Texas is arguably the last remaining state with sufficient habitat to provide quail-hunting opportunities on a grand scale, and Texas ranchers with good bobwhite habitat often generate a greater proportion of their income from fees paid by quail hunters than from livestock production. Managing and expanding bobwhite habitat makes good sense economically, and it benefits the environment as well. The rangelands and woodlands of Texas that produce quail also support scores of other species of wildlife. Texas Bobwhites is a field guide to the seeds commonly eaten by northern bobwhites, as well as a handbook for conserving and improving northern bobwhite habitat. It provides identifying characteristics for the seeds of 91 species of grasses, forbs, woody plants, and succulents. Each seed description includes a close-up and a scale photo of the seed and the plant that produces it, along with a range map. Using this information, hunters can readily identify concentrations of plants that are most likely to attract quail. Landowners and rangeland managers will greatly benefit from the book's state-of-the-art guidance for habitat management and restoration, including improving habitat dominated by invasive and nonnative grasses.
