Chemistry of Love and Sex is a chemist's guide to the chemical phenomena and molecules associated with endogenous hormonal mechanisms and brain neurotransmission - the basis of many emotions associated with love, passion, and sex.
Chemistry of Love and Sex demonstrates how these substances interact and "play" with each other in the different phases of human relationships. External factors which may influence love and sex, such as pharmaceuticals, cosmetics or food are also considered.

The identification and quantification of the widespread occurrence of trace organic chemicals at minute concentrations in the aqueous environment impacted by human activities is a result of rapid advances in environmental analytical chemistry. The body of knowledge regarding the characterization, fate and transport of these chemicals of emerging concern (CECs) in the natural water environment and engineered water treatment processes, as well as their toxicity, has grown substantially over the last two decades. Recently, the focus in the environmental chemistry community has shifted from these CEC parent compounds to the fate, transport, and toxicity of transformation products, which are generated through abiotic and biotic mechanisms in natural systems and during engineered advanced water treatment processes. This two-part book focuses on the studies and recent advancements towards the development of more harmonized strategies and workflows using non-target and suspects screening methods, including suitable bioassay approaches to assess the overall relevance of transformation products. Volume I covers the relevance of transformation products and international strategies to manage CECs, new methods for a comprehensive assessment of transformation products, and the fate and transport of transformation products in natural systems. This book is ideal for environmental scientists and engineers, particularly chemists, environmental engineers, public health officials, regulators, other chemistry-related professionals, and students.

A unified theory of conservation that addresses the broad problem of conservation, the principles that inform conservation choices, and the application of those principles to the management of the natural world. The conservation of natural resources, like that of any other asset, involves trade-offs. Yet, in a world faced with the harsh realities of climate change, crafting the right environmental policies is an increasingly urgent task. In Conservation, Charles Perrings and Ann Kinzig bring together new research in economics and biodiversity to investigate conservation decisions and the theory behind them. Perrings and Kinzig apply the concept of conservation broadly to examine how the principles of conservation apply to the management of the natural world. They demonstrate that the same basic principles serve as the foundation of all rational conservation decisions, from managing financial assets to safeguarding at-risk ecosystems. Whether someone is deciding to hold or dispose of a stock or whether to exploit or preserve a natural resource, they are better off choosing to conserve a resource when its value to them, if conserved, is greater than its value when converted. The book also considers the context of such conservation decisions. Just as national tax rules influence choices about financial investments, environmental regulations within countries, and environmental agreements between countries, impact the decisions regarding natural resources. Building on their basic theory of conservation, Perrings and Kinzig address key issues in the field of environmental economics, including the valuation of ecosystem services and environmental assets; the limits on the substitutability of produced and natural capital; and the challenges posed by the often weak markets for ecosystem services oriented toward the public good. They also address the problem of scale: while decisions might be easier to make at the local level, many conservation policies need to apply at either the national or international level to succeed. Written by experts from both social and hard sciences, this book presents a unified theory of conservation and provides a model for a more effective way to approach the vitally important issue.

""This book should become an indispensable asset on the bookshelves of pharmaceutical laboratories in academia and in industry, as well as of laboratories devoted to plant protection. I am convinced that studying this book will be an eye-opener for many scientists in the field of life sciences. Furthermore, for teachers in this area it will not only be a useful compilation of the various languages and definitions of organic stereochemistry, but also a welcome source of examples for demonstrating to their students the intricate and intriguing role stereochemistry plays in the chemistry of life."" -Prof. Dr. Dieter Seebach, Laboratory of Organic Chemistry, ETH Zurich, Switzerland

This textbook presents the molecular scale of matter in the broad diversity and richness of its three dimensions, giving due attention when relevant to the temporal dimension in which molecules exist, act, and react.

The focus is on two significant fields of three-dimensional chemistry: a presentation of the guiding principles in organic stereochemistry, followed by a focus on the biochemical and medicinal relevance of this discipline.

The treatment of "Guiding Principles "gives priority to didactic clarity and nomenclature issues, as detailed and illustrated in Parts 1 to 4: '"Symmetry Elements and Operations, Classification of Stereoisomers"''"Stereoisomerism Resulting from One or Several Stereogenic Centers"''"Other Stereogenic Elements: Axes of Chirality, Planes of Chirality, Helicity, and ("E," "Z")-Diastereoisomerism"''"Isomerisms about Single Bonds and in Cyclic Systems"'

This is followed by Parts 5 to 8 which focus on the biomedicinal relevance of stereochemistry, with special reference to the biochemistry and pharmacology of medicinal compounds.

Here, examples and applications are discussed and illustrated based on their relevance to a given specific stereochemical aspect: '"Chirality in Molecular and Clinical Pharmacology"''"The Conformational Factor in Molecular Pharmacology"''"The Concept of Substrate Stereoselectivity in Biochemistry and Xenobiotic Metabolism"''"Prostereoisomerism and the Concept of Product Stereoselectivity in Xenobiotic Metabolism"'

Finally, the book contains a gift for broad-minded readers with an interest in the historical roots of stereochemistry: Part 9: '"Molecular Chirality in Chemistry and Biology: Historical Milestones"'

Moritz Schulz explores counterfactual thought and language: what would have happened if things had gone a different way. Counterfactual questions may concern large scale derivations (what would have happened if Nixon had launched a nuclear attack) or small scale evaluations of minor derivations (what would have happened if I had decided to join a different profession). A common impression, which receives a thorough defence in the book, is that oftentimes we find it impossible to know what would have happened. However, this does not mean that we are completely at a loss: we are typically capable of evaluating counterfactual questions probabilistically: we can say what would have been likely or unlikely to happen. Schulz describes these probabilistic ways of evaluating counterfactual questions and turns the data into a novel account of the workings of counterfactual thought.

Manganese (Mn) oxides are among the most reactive minerals in the earth's surface environment, and play a significant role in adsorption, co-precipitation and redox reactions, affecting biogeochemical cycles of numerous nutrients and contaminants. In addition, manganese oxides are widely applied as absorbents, ion sieves, chemical oxidants and catalysts for environmental remediation and pollution control. There are, however, still many aspects poorly understood in terms of the environmental geochemistry of manganese oxides, such as biogenic formation mechanisms, detailed crystal structure of nanocrystalline phases, electron transfer paths in redox reactions, adsorption mechanisms of contaminants on surfaces, physiochemical factors controlling the contents of structural Mn(III) and vacant sites that largely determine Mn oxide reactivity, and the role of Mn(III) in the above processes. This book aims to bring together advances on manganese oxide environmental biogeochemistry from leading scientists in multiple disciplines, e.g., mineralogy, geochemistry, soil science and environmental engineering. A number of frontier research topics are included in the book, such as in-situ characterization of Mn oxide reactivity with As and Cr, kinetics and molecular-scale mechanisms of metal oxidation by mangnese oxides, mechanistic understanding of metal sorption through density function theory, the role of surface edge sites of birnessites in metal(loid) sorption, reactivity of natural crytomelane, pathways of phyllomanganate transformation to todorokite, water-oxidation catalysis by manganese oxides, in situ As immobilization using stabilized Fe-Mn binary oxides, and synthesis of Li ion-sieves from biogenic oxides and stability of colloidal Mn oxides. The book should be of interest to scientists and engineers in a broad range of disciplines, such as geochemistry, soil science, mineralogy, microbiology, materials science, and environment engineering, as well as graduate students who are engaged in research on manganese oxide biogeochemistry and the engineering application of Mn-bearing materials.

J.B.S. Haldane (1892-1964) is widely appreciated as one of the greatest and most influential British scientists of the 20th century, making significant contributions to genetics, physiology, biochemistry, biometry, cosmology, and other sciences. More remarkable, then, is the fact that Haldane had no formal qualification in science. He made frequent appearances in the media, making pronouncements on a variety of poignant topics including mining disasters, meteorites, politics, and the economy, and was a popular scientific essay writer. Haldane also was famed for conducting painful experiments on himself, including several instances in which he permanently himself. A staunch Marxist and convert to Hinduism, Haldane lived a diverse, lively and interesting life that is still revered by today's science community. A biography of Haldane has not been attempted since 1968, and that book provided an incomplete account of the man's scientific achievement. "The Life and Works of J.B.S. Haldane" serves to fix this glaring omission, providing a complete biographical sketch written by Krishna Dronamraju, one of the last living men to have worked personally with Haldane. A new genre of biographies of 20th-century scientists has come into being, and thus far works have been written about men like Einstein, Oppenheimer, Bernal, Galton, and many more; the inclusion of Haldane within this genre is an absolute necessity. Dronamraju evaluates Haldane's social and political background, as well as his scientific creativity and accomplishments. Haldane embodies a generation of intellectuals who believed and promoted knowledge for its own sake, and that spirit of scientific curiosity and passion is captured in this biography.

The bond valence model, a description of acid-base bonding, is widely used for analysing and modelling the structures and properties of solids and liquids. Unlike other models of inorganic chemical bonding, the bond valence model is simple, intuitive, and predictive, and is accessible to anyone with a pocket calculator and a secondary school command of chemistry and physics. This new edition of 'The Chemical Bond in Inorganic Chemistry: The Bond Valence Model' shows how chemical properties arise naturally from the conflict between the constraints of chemistry and those of three-dimensional space. The book derives the rules of the bond valence model, as well as those of the traditional covalent, ionic and popular VSEPR models, by identifying the chemical bond with the electrostatic flux linking the bonded atoms. Most of the new edition is devoted to showing how to apply these ideas to real materials including crystals, liquids, glasses and surfaces. The work includes detailed examples of applications, and the final chapter explores the relationship between the flux and quantum theories of the bond.

In the past few years, the subject of climate change has frequently garnered headlines due to the usual political controversy surrounding it. However, setting aside the argument as to whether climate change is a man-made effect or not, we cannot deny the fact that humanity has been discharging carbon increasingly into the atmosphere for centuries. Likewise, similar reports on the growing Great Pacific Garbage Patch-and the general accumulation of plastics everywhere-are alarming. Moreover, it has also been recently demonstrated that microplastics are finally entering the food webs which include the human consumer. Air, soil, and water pollution are increasing; in some ways forcing certain countries and governments to modify their politics, while also creating new opportunities and opening new niches for the marketing of products, such as air and water filters. With current techniques, it is not possible to completely eliminate all toxic and hazardous waste, which means that security deposits are necessary. Security deposits are storage areas prepared for certain toxic and dangerous industrial waste, so that its harmful properties cannot affect the natural environment and human health-at least, in any case, for a very long time. Due to their geomorphological composition, topography, and hydrographic conditions, there are sites that can be used as waste deposits, given their natural isolation and projected stability for hundreds of years. Thus, they become security deposits. In addition, every day new materials and construction techniques are developed that allow for a total isolation of the waste. A relatively new view in the material life cycle is the reuse of the generated waste as new resources. This helps to mitigate the cost increases in raw materials, energy, and regulations regarding waste disposal, which have caused the industry to rethink its production methods, leading to a better use of raw materials and energy. Clean technologies are those used by the industry to reduce the need for treatment or disposal of waste and to reduce the demand for raw materials, energy, and water. For the proper implementation of clean technologies, industries and municipalities must develop a deep understanding of their own processes and activities, and must analyze the characteristics of their equipment and make any possible modifications. An environmental evaluation of the situation provides suitable information on the efficiency of each component and its integration in the whole process, on the proportion of waste, on energy consumption, and on how to reorganize or modify to improve cost-efficiency in economic and environmental terms, which in a middle term view results in synergistic goals. With this concise introduction to the world of waste and pollutant treatment technologies, the editors believe it is clear that the solutions are to be developed on a case-by-case basis; because the larger the number of mixed pollutants, the more complex and intimated the process will be. This book presents a series of selected approaches that can be used to approach different cases, also depending upon budget and viability of a sustainable approach. This book serves as a source of information, triggers ideas, and fosters interaction between all the players taking action in sustainable development initiatives.

Information literacy-the ability to find, evaluate, and use information resources-is an important skill for future chemists. Students and scientists need to distinguish between information provided by Wikipedia, ChemSpider, research journals, and The New York Times, depending on the intended use of the information sought. Instructors and librarians may often teach these skills through stand-alone database demonstrations, video tutorials, and lectures. However, it is possible to teach these skills in a more contextual and integrated manner by designing chemistry assignments that incorporate information literacy as a learning outcome. This book will prove useful for librarians and chemistry instructors who are designing courses in which students develop information literacy in the context of a chemistry course at two-year colleges, public and private universities, and high schools. The chapters in this book review the current state of information literacy in chemistry and provide concrete examples of assignments and interventions aimed at teaching information literacy skills in chemistry curricula. A wide range of options are offered for integrating information literacy into college-level chemistry courses, including general chemistry, organic chemistry, science courses for students not majoring in science, and chemistry capstone research courses.

According to the cognitive penetrability hypothesis, our beliefs, desires, and possibly our emotions literally affect how we see the world. This book elucidates the nature of the cognitive penetrability and impenetrability hypotheses, assesses their plausibility, and explores their philosophical consequences. It connects the topic's multiple strands (the psychological findings, computationalist background, epistemological consequences of cognitive architecture, and recent philosophical developments) at a time when the outcome of many philosophical debates depends on knowing whether and how cognitive states can influence perception. All sixteen chapters were written especially for the book. The first chapters provide methodological and conceptual clarification of the topic and give an account of the relations between penetrability, encapsulation, modularity, and cross-modal interactions in perception. Assessments of psychological and neuroscientific evidence for cognitive penetration are given by several chapters. Most of the contributions analyse the impact of cognitive penetrability and impenetrability on specific philosophical topics: high-level perceptual contents, the epistemological consequences of penetration, nonconceptual content, the phenomenology of late perception, metacognitive feelings, and action. The book includes a comprehensive introduction which explains the history of the debate, its key technical concepts (informational encapsulation, early and late vision, the perception-cognition distinction, hard-wired perceptual processing, perceptual learning, theory-ladenness), and the debate's relevance to current topics in the philosophy of mind and perception, epistemology, and philosophy of psychology.

Containing fully worked-out solutions to all of the odd-numbered exercises in the text, this manual gives you a way to check your answers and ensure that you have taken the correct steps to arrive at an answer.

Probability is an area of mathematics of tremendous contemporary importance across all aspects of human endeavour. This book is a compact account of the basic features of probability and random processes at the level of first and second year mathematics undergraduates and Masters' students in cognate fields. It is suitable for a first course in probability, plus a follow-up course in random processes including Markov chains. A special feature is the authors' attention to rigorous mathematics: not everything is rigorous, but the need for rigour is explained at difficult junctures. The text is enriched by simple exercises, together with problems (with very brief hints) many of which are taken from final examinations at Cambridge and Oxford. The first eight chapters form a course in basic probability, being an account of events, random variables, and distributions - discrete and continuous random variables are treated separately - together with simple versions of the law of large numbers and the central limit theorem. There is an account of moment generating functions and their applications. The following three chapters are about branching processes, random walks, and continuous-time random processes such as the Poisson process. The final chapter is a fairly extensive account of Markov chains in discrete time. This second edition develops the success of the first edition through an updated presentation, the extensive new chapter on Markov chains, and a number of new sections to ensure comprehensive coverage of the syllabi at major universities.

The Two Selves takes the position that the self is not a "thing" easily reduced to an object of scientific analysis. Rather, the self consists in a multiplicity of aspects, some of which have a neuro-cognitive basis (and thus are amenable to scientific inquiry) while other aspects are best construed as first-person subjectivity, lacking material instantiation. As a consequence of its potential immateriality, the subjective aspect of self cannot be taken as an object and therefore is not easily amenable to treatment by current scientific methods. Klein argues that to fully appreciate the self, its two aspects must be acknowledged, since it is only in virtue of their interaction that the self of everyday experience becomes a phenomenological reality. However, given their different metaphysical commitments (i.e., material and immaterial aspects of reality), a number of issues must be addressed. These include, but are not limited to, the possibility of interaction between metaphysically distinct aspects of reality, questions of causal closure under the physical, the principle of energy conservation, and more. After addressing these concerns, Klein presents evidence based on self-reports from case studies of individuals who suffer from a chronic or temporary loss of their sense of personal ownership of their mental states. Drawing on this evidence, he argues that personal ownership may be the factor that closes the metaphysical gap between the material and immaterial selves, linking these two disparate aspects of reality, thereby enabling us to experience a unified sense of self despite its underlying multiplicity.

The latest edition of Animal Nutrition has been updated thoroughly to provide a clear and comprehensive introduction to the science and practice of animal nutrition. This classic, market-leading text is a trusted resource for undergraduates studying Animal Science, Veterinary Science, Agriculture, Biology and Biochemistry. It is supported by key experimental evidence throughout about modern advancements in animal food nourishment, composition of foods and feeding standards for dairy and beef cattle, sheep, pigs and poultry, horses, and cats and dogs. It is split into six main sections covering: The components of food; The digestion and metabolism of nutrients; Quantifying the nutrient content of foods: digestibility, energy and protein values; The nutrient requirements of animals; The nutritional characteristics of foods; and Animal products and human nutrition. Quantitative aspects of the subject are clearly explained and illustrated by worked examples. Problems have been added to all chapters to aid student learning and the appendices include solutions to all chapter-end numeric questions. This edition includes nutritional topics related to molecular biology, the environment, and companion animals - dog and cat nutrition has been expanded. Under nutrient requirements of animals, usage of novel foods such as insects has also been added. Chapter-end summaries and questions allow students to recap and test their knowledge of the chapter topic.

Metaphysicians should pay attention to quantum mechanics. Why? Not because it provides definitive answers to many metaphysical questions-the theory itself is remarkably silent on the nature of the physical world, and the various interpretations of the theory on offer present conflicting ontological pictures. Rather, quantum mechanics is essential to the metaphysician because it reshapes standard metaphysical debates and opens up unforeseen new metaphysical possibilities. Even if quantum mechanics provides few clear answers, there are good reasons to think that any adequate understanding of the quantum world will result in a radical reshaping of our classical world-view in some way or other. Whatever the world is like at the atomic scale, it is almost certainly not the swarm of particles pushed around by forces that is often presupposed. This book guides readers through the theory of quantum mechanics and its implications for metaphysics in a clear and accessible way. The theory and its various interpretations are presented with a minimum of technicality. The consequences of these interpretations for metaphysical debates concerning realism, indeterminacy, causation, determinism, holism, and individuality (among other topics) are explored in detail, stressing the novel form that the debates take given the empirical facts in the quantum domain. While quantum mechanics may not deliver unconditional pronouncements on these issues, the range of possibilities consistent with our knowledge of the empirical world is relatively small-and each possibility is metaphysically revisionary in some way. This book will appeal to researchers, students, and anybody else interested in how science informs our world-view.

Significant advances in science bring new understandings of the human as a unity of mind, body and world and calls into question the deep-seated dualistic presuppositions of modern theology. Oliver Davies argues that the changing framework allows a return to the defining question of the Easter Church: 'Where is Jesus Christ?'. This is a question which can bring about a fundamental re-orientation of theology, since it gives space for the theological reception of the disruptive presence of the living Christ as the present material as well as formal object of theology in the world. At the centre of this study therefore is a new theology of the doctrine of the exaltation of Christ, based upon St Paul's encounter with the exalted or commissioning Christ on the road to Damascus. This places calling and commissioning at the centre of systematic theology. It provides the ground for a new understanding of theology as transcending the Academy-Church division as well as the divide between systematic and practical theology. It points also to a new critical theological method of engagement and collaboration. This book begins to explore new forms of world-centred theological rationality in the contexts not only of scripture, doctrine, anthropology, ecclesiology and faith, but also of Christian politics and philosophy. It is a work of contemporary and global Christological promise in Fundamental Theology, and is addressed to all those who are concerned, from whichever denomination, with the continuing vitality of Christianity in a changing world.

Engineering is mathematics in action. But engineering students do not always see the link between what they learn in mathematics and how this applies to engineering problems.

From relatively simple questions, like determining the maximum weight a beam can support to complex projects like mapping out the most efficient electrical flow for a city’s traffic lights, mathematics is essential.

Even the most cursory survey of the chemical literature reveals that modern NMR spectroscopy has indeed fulfilled its potential as a powerful and indispensable tool for probing molecular structure, providing detail that is comparable to, and sometimes surpasses that, of X-ray crystallography. As NMR spectroscopy's 70th anniversary approaches, the diversity of chemical problems to which this technique can be applied continues to grow across many scientific fields. Beyond the laboratory setting, the technology underlying NMR is now a widely used and critical medical diagnostic technique, Magnetic Resonance Imaging (MRI). Unfortunately, the number of applications of NMR spectroscopy across so many STEM-related fields presents significant challenges in how best to introduce this powerful technique in meaningful ways at the undergraduate level. Inspired by the development of the field, and building upon the work of previous symposia and an ACS symposium series book on this topic (3), a symposium was developed, entitled "NMR Spectroscopy in the Undergraduate Curriculum," for the 239th American Chemical Society National Meeting in San Francisco. This book brings together all of the presenters who have been successful in developing and successfully integrating NMR spectroscopy pedagogy across their undergraduate curriculums. Their knowledge and experiences will aid readers who are interested in expanding and invigorating their own curriculum.

The first single, comprehensive source for locating North American public prairies, grasslands, and savannas, Prairie Directory of North America is a guide unlike any other. First published in 2001, the book uniquely catalogs the continent's most well-known prairie sites by country and state for easy reference. With the addition of over three hundred newly located, preserved, or restored sites, the second edition is the prairie enthusiast's ideal guide to locating countless North American sites-from the well-documented to the remote. Readers can use the guide to plan both convenient visits to close-to-home prairies and journeys to sites well across the continent. Also included is an expanded state-by-state index, ideal for locating specific prairies in any given state. The victim of destructive plowing and construction at the hands of European settlers, North American grassland ecosystems that once spanned the entire continent have suffered degradation and fragmentation. With the Prairie Directory as a guide, however, ecologists, environmental scientists, and tourists can experience the essence of this ancient ecosystem and, in some locations, even its vastness. The book lists tiny, hidden half-acre prairies spared by the plow as well as popular sites covering millions of acres. It documents prairies hidden deep in forests or in plain sight in American Indian reservations. The only one of its kind, this book will allow readers to experience the prairie as a colorful, fragrant, wildlife-rich North American landscape.

An updated Smartwork5 course and new active learning resources provide flexible options for high-quality assessment in and outside of class.

A tightly argued and expansive examination of the pitfalls of transhumanism that reacquaints us with what it means to live well. Advocates of transhumanism, or "radical" enhancement, urge us to pursue the biotechnological heightening of select capacities - above all, cognitive ability - so far beyond any human limit that the beings with those capacities would exist on a higher ontological plane. For proponents of such views, humanity's self-transcendence through advancements in science and technology may even be morally required. Consequently, the human stakes of how we respond to transhumanism are immeasurably high. In Posthuman Bliss? The Failed Promise of Transhumanism, Susan B. Levin challenges transhumanists' overarching commitments regarding the mind and brain, ethics, liberal democracy, knowledge, and reality, showing their notion of humanity's self-transcendence into "posthumanity" to be little more than fantasy. Uniting philosophical with scientific arguments, Levin mounts a significant challenge to transhumanists' claim that science and technology support their vision of posthumanity. In a clear and engaging style, she dismantles transhumanists' breezy assurances that posthumans will emerge if we but allocate sufficient resources to that end. Far from offering theoretical and practical "proof of concept" for the vision that they urge upon us, Levin argues, transhumanists engage inadequately with cognitive psychology, biology, and neuroscience, often relying on questionable or outdated views within those fields. Having shown in depth why transhumanism should be rejected, Levin argues forcefully for a holistic perspective on living well that is rooted in Aristotle's virtue ethics but that is adapted to liberal democracy. This holism is thoroughly human, in the best of senses: It directs us to consider worthy ends for us as human beings and to do the irreplaceable work of understanding ourselves rather than relying on technology and science to be our salvation.

Niels Bohr and the Quantum Atom is the first book that focuses in detail on the birth and development of Bohr's atomic theory and gives a comprehensive picture of it. At the same time it offers new insight into Bohr's peculiar way of thinking, what Einstein once called his 'unique instinct and tact'. Contrary to most other accounts of the Bohr atom, the book presents it in a broader perspective which includes the reception among other scientists and the criticism launched against it by scientists of a more conservative inclination. Moreover, it discusses the theory as Bohr originally conceived it, namely, as an ambitious theory covering the structure of atoms as well as molecules. By discussing the theory in its entirety it becomes possible to understand why it developed as it did and thereby to use it as an example of the dynamics of scientific theories.
