Severe Weather
by National GeographicWeather-related tragedies have fascinated humans throughout time. For those who loved The Perfect Storm andKrakatoa, the millions who log onto daily weather forecasting sites and check weather apps, and people who can't get enough front-page headlines of global natural disasters. Earthquakes, hurricanes, tornados, floods, forest fires, blizzards, and thunderstorms: National Geographic explores the deadliest of these disasters throughout history and arms you with ways to protect yourself from chaos and destruction. From the 1906 earthquake that flattened San Francisco and the morbid 1889 flash flood that wiped out the entire town of Johnstown, Pennsylvania, to the Superstorm of 1993 that blanketed Florida in snow and the more recent East Coast and Gulf Coast ravages of hurricanes Katrina and Sandy, the destructive force and human tragedy both fascinates and horrifies. In addition to these gripping stories, NGS provides practical tips for surviving at home and weathering the lethal strength of these events if caught outside.
Sewage and Biomass from Wastewater to Energy: Possibilities and Technology
by Inamuddin Mohammad Luqman Tariq Altalhi Joseph KapukuWritten and edited by a team of industry experts, this exciting new volume covers clean energy production from sewage and biomass while achieving a zero-waste strategy. Wastewater treatment plants are critical in protecting both the environment’s resources and human health. A wastewater treatment plant’s technological system focuses not only on the effectiveness of the treatment but on the costs and energy consumption of the entire system. Municipal wastewater treatment produces a significant amount of sewage sludge all over the world. The majority of this sludge’s dry matter content is made up of organic compounds which are not toxic, and they consist of both primary and secondary (microbiological) sludge. There is also a substantial quantity of inorganic substances in the sludge, along with a small quantity of toxic matter. Also, various raw sewage treatment options can include energy production (heat, electricity, or biofuel) to reduce dependence on external energy supply during treatment. The most important options used for energy production from sewage and biomass can use the following approaches: anaerobic digestion, co-digestion, incineration with energy recovery, co-incineration, pyrolysis, gasification, supercritical (wet) oxidation, and hydrolysis. Generally, these processes or methods are cost-effective, but they can still have some setbacks related to the nature of the methods or the raw material used for conversion. There are also operating conditions to comply with to get a successful outcome. This book combines information from many disciplines related to wastewater treatment technologies to show how the circular economy approach can be used to achieve zero waste and produce energy that can be useful for plants and communities. This approach focuses on clean technologies for green energy resources such as biohydrogen, biofuels, and biogas from biomass and sewage sludge for zero waste production. This is aimed to also integrate the issue of energy demand and the one of energy production.
Sex Addiction as Affect Dysregulation: A Neurobiologically Informed Holistic Treatment (Norton Series On Interpersonal Neurobiology Ser. #0)
by Alexandra KatehakisExamining the neurobiological underpinnings of sex addiction. Neuroaffective science—studying the integrated development of the body, brain, and mind—has revealed mechanisms linking psychological and biological factors of mental disorders, including addiction. Indeed, its paradigm-shifting theoretical umbrella demonstrated that substance and behavioral dependencies share identical neurobiological workings, and thus that problematic repetitive behaviors are genuine addictions—a state increasingly understood as a chronic brain disorder. Clinical experience strongly suggests that sex addiction (SA) treatment informed by affective neuroscience—the specialty of Alexandra Katehakis—proves profoundly transformative. Katehakis's relational protocol, presented here, blends neurobiology with psychology to accomplish full recovery. Her Psychobiological Approach to Sex Addiction Treatment (PASAT) joins therapist and patient through a relationally-based psychotherapy—a holistic, dyadic dance that calls on the body, brain, and mind of both. Written with clarity and compassion, this book integrates cutting-edge research, case studies, verbatim session records, and patient writings and art. Katehakis explicates neurophysiological, psychological, and cultural forces priming and maintaining SA, then details how her innovative treatment restores patients' interpersonal, sexual, and spiritual relationality.

Sex Differences in Brain Function and Dysfunction (Current Topics in Behavioral Neurosciences #62)
by Claire Gibson Liisa A. M. GaleaDoes sex matter when it comes to brain function? This volume attempts to answer this very important question which is of relevance to the disciplines of psychology, neuroscience, psychiatry and neurology. Understanding how brain function and resultant behaviors may differ between the sexes impacts upon our knowledge of the pathology and development of treatments for various neurological and psychiatric disorders, particularly those that show significant sex differences in either prevalence and/or manifestation of symptoms. This volume covers three main themes of research into sex differences in basic neurobiology, psychology, preclinical research and clinical research. It begins by exploring our understanding of sex and gender in relation to both animal and human behaviors and discusses the relevance, and importance, of considering sex and gender when conducting research into brain function and behaviors. The second theme focuses on how sex and gender influence mental health and considers the impact of our immune system and the changes that occur with ageing. Finally, the third aspect focuses on examples of neurological disorder which show sex differences in terms of their aetiology and/or symptomology and considers the relevance in the development of treatment for these disorders including dementia, stroke and multiple sclerosis. This volume is of considerable interest to mental health and neurology professionals, including psychiatrists, neurologists, nurses, allied health clinicians and pharmacists. It is also helpful and important for preclinical researchers working in neuroscience, psychopharmacology and reproductive endocrinology.
Sex Differences in Heart Disease (Advances in Biochemistry in Health and Disease #21)
by Bohuslav Ostadal Naranjan S. DhallaCardiovascular diseases are the leading cause of mortality in men and women. Unfortunately, women have traditionally been excluded from clinical trials, and female animals have been used less or sex was not reported in basic research studies. Until recently, consideration of both sexes was not required in clinical and preclinical studies focusing on cardiovascular diseases. However, the number of clinical and experimental papers dealing with sex differences and heart disease significantly increases during the last years. This trend is obviously the result of at least two facts: the number of examples of different behavior of the male and female heart under physiological and pathological conditions is steadily increasing and there were controversial reports on the beneficial and adverse effect of hormonal replacement therapy. Detailed molecular and cellular mechanisms of these differences are still unknown but one is clear already today: sex differences are so important that they should be considered by the selection of optimum diagnostic and therapeutic procedures in clinical practice.The book presents 16 manuscripts on sex differences of heart disease, as developed by several investigators; the volume is organized in four parts. Part I, dealing with sex differences in cardiac ischemic injury, includes 5 chapters on experimental aspects of cardiac ischemia/reperfusion injury, the role of testosterone, and clinical aspects of ischemic heart disease. Part II is devoted to sex differences in heart failure and includes four chapters. Discussion in this part of the book is centered around the sex differences in heart failure due to volume overload. Part III of this volume includes four papers on risk factors of cardiovascular diseases, namely hypertension and obesity, and, finally, three chapters in part IV deal with sex differences of cardiac mitochondria under different pathological conditions. We believe this book will be very useful for cardiovascular scientists, graduate students, postdoctoral fellows and other health professionals.
Sex Hormones and Immunity to Infection
by Craig Roberts Sabra L. KleinWhy sex matters Among human and nonhuman animals, the prevalence and intensity of infection typically is higher in males than females and may reflect differences in exposure as well as susceptibility to pathogens. Elevated immunity among females is a double-edged sword in which it is beneficial against infectious diseases but is detrimental in terms of increased development of autoimmune diseases. The present book critically reviews the evolutionary origin and the functional mechanisms responsible for sexual dimorphism in response to infection. It emphasizes the value of examining responses in both males and females to improve our understanding about host-pathogen interactions in both sexes. The contributors are experts in their specific disciplines which range from microbiology and immunology to genetics, pathology, and evolutionary biology. The book aims at bringing insight to the treatment and management of infectious diseases; it delineates areas where knowledge is lacking and highlights future avenues of research.
Sex Is a Spectrum: The Biological Limits of the Binary
by Agustín FuentesWhy human biology is far more expansive than the simple categories of female and maleBeing human entails an astonishingly complex interplay of biology and culture, and while there are important differences between women and men, there is a lot more variation and overlap than we may realize. Sex Is a Spectrum offers a bold new paradigm for understanding the biology of sex, drawing on the latest science to explain why the binary view of the sexes is fundamentally flawed—and why having XX or XY chromosomes isn&’t as conclusive as some would have us believe.In this lively and provocative book, leading biological anthropologist Agustín Fuentes begins by tracing the origin and evolution of sex, describing the many ways in the animal kingdom of being female, male, or both. Turning to humans, he presents compelling evidence from the fossil and archaeological record that attests to the diversity of our ancestors&’ sexual bonds, gender roles, and family and community structures, and shows how the same holds true in the lived experiences of people today. Fuentes tackles hot-button debates around sports and medicine, explaining why we can acknowledge that females and males are not the same while also embracing a biocultural reality where none of us fits neatly into only one of two categories.Bringing clarity and reason to a contentious issue, Sex Is a Spectrum shares a scientist&’s perspective on why a binary view of sex and gender is not only misguided but harmful, and why there are multitudes of ways of being human.
Sex Itself: The Search for Male and Female in the Human Genome
by Sarah S. RichardsonHuman genomes are 99. 9 percent identicalOCowith one prominent exception. Instead of a matching pair of X chromosomes, men carry a single X, coupled with a tiny chromosome called the Y. aTracking the emergence of a new and distinctive way of thinking about sex represented by the unalterable, simple, and visually compelling binary of the X and Y chromosomes, "Sex Itself" examines the interaction between cultural gender norms and genetic theories of sex from the beginning of the twentieth century to the present, postgenomic age. aaaaaaaaaaaUsing methods from history, philosophy, and gender studies of science, Sarah S. Richardson uncovers how gender has helped to shape the research practices, questions asked, theories and models, and descriptive language used in sex chromosome research. From the earliest theories of chromosomal sex determination, to the mid-century hypothesis of the aggressive XYY supermale, to the debate about Y chromosome degeneration, to the recent claim that male and female genomes are more different than those of humans and chimpanzees, Richardson shows how cultural gender conceptions influence the genetic science of sex. aaaaaaaaaaaaRichardson shows how sexual science of the past continues to resonate, in ways both subtle and explicit, in contemporary research on the genetics of sex and gender. With the completion of the Human Genome Project, genes and chromosomes are moving to the center of the biology of sex. "Sex Itself" offers a compelling argument for the importance of ongoing critical dialogue on how cultural conceptions of gender operate within the science of sex. "
Sex Robots and Vegan Meat: Adventures at the Frontier of Birth, Food, Sex, and Death
by Jenny KleemanA timely investigation into the forces that are driving innovation in the four core areas of human experience: birth, food, sex, and death.In Sex Robots & Vegan Meat, award-winning journalist and documentary-maker Jenny Kleeman takes us on a journey into the world of the people who are changing what it means to be human. Focusing on four central pillars of the human experience–birth, food, sex, and death—Kleeman examines the people who are driving some truly amazing (and perhaps worrying) innovations. We are on the brink of seismic changes in the ways we live and die, from babies grown in artificial wombs to lab-produced meat; from sex robots able to hold polite conversation (and otherwise) to being able to choose to end our days with the perfect, painless, automated death. Our journey from cradle to grave is developing in ways which involve more and more technology, and less and less human interaction. Might these advances in technology serve to rob us of our humanity? In this book Jenny Kleeman takes a profound look at what the future might have in store—and asks some provocative questions along the way. Jenny Kleeman places these scientists front and center and asks what is driving and motivating them? Are they entrepreneurs in it for the greater good of human advancement, or might there be more sinister—i.e. monetary—motivations in play? Gleeman is a skilled and subtle interrogator and travels with the reader on a fascinating exploration of the changes afoot, their implications for who we are as a society—and as human beings. It's an immersive, eye-opening, and hugely entertaining journey into a world of extraordinary visionaries on the frontline of a social revolution.

Sex and Friendship in Baboons (Evolutionary Foundations Of Human Behavior Ser.)
by Barbara B. SmutsThose who have been privileged to watch baboons long enough to know them as individuals and who have learned to interpret some of their more subtle interactions will attest that the rapid flow of baboon behavior can at times be overwhelming. In fact, some of the most sophisticated and influential observation methods for sampling vertebrate social behavior grew out of baboon studies, invented by scientists who were trying to cope with the intricacies of baboon behavior. Barbara Smuts' eloquent study of baboons reveals a new depth to their behavior and extends the theories needed to account for it.While adhering to the most scrupulous methodological strictures, the author maintains an open research strategy--respecting her subjects by approaching them with the open mind of an ethnographer and immersing herself in the complexities of baboon social life before formulating her research design, allowing her to detect and document a new level of subtlety in their behavior. At the Gilgil site, described in this book, she could stroll and sit within a few feet of her subjects. By maintaining such proximity she was able to watch and listen to intimate exchanges within the troop; she was able, in other words, to shift the baboons well along the continuum from ""subject"" to ""informant."" By doing so she has illuminated new networks of special relationships in baboons. This empirical contribution accompanies theoretical insights that not only help to explain many of the inconsistencies of previous studies but also provide the foundation for a whole new dimension in the study of primate behavior: analysis oft he dynamics of long-term, intimate relationships and their evolutionary significance.At every stage of research human observers have underestimated the baboon. These intelligent, curious, emotional, and long-lived creatures are capable of employing stratagems and forming relationships that are not easily detected by traditional research methods. In the process

Sex and the Brain
by Gillian EinsteinThis collection of foundational papers on sex differences in the brain traces the development of a much-invoked, fast-growing young field at the intersection of brain and behavior. The reader is introduced to the meaning and nature of sexual dimorphisms, the mechanisms and consequences of steroid hormone action, and the impact of the field on interpretations of sexuality and gender. Building on each other in point-counterpoint fashion, the papers tell a fascinating story of an emerging science working out its core assumptions. Experimental and theoretical papers, woven together by editor's introductions, open a window onto knowledge in the making and a vigorous debate between reductionist and pluralist interpreters. Five major sections include papers on conceptual and methodological background, central nervous system dimorphisms, mechanisms for creating dimorphisms, dimorphisms and cognition, and dimorphisms and identity. Each section builds from basic concepts to early experiments, from experimental models to humans, and from molecules to mind. Papers by such leading scholars as Arthur Arnold, Frank Beach, Anne Fausto-Sterling, Patricia Goldman-Rakic, Doreen Kimura, Simon LeVay, Bruce McEwen, Michael Merzenich, Bertram O'Malley, Geoffrey Raisman, and Dick Swaab, illustrate a rich blend of perspectives, approaches, methods, and findings. Sex and the Brainwill show students how a scientific paper can be analyzed from many perspectives, and supply them with critical tools for judging a rapidly emerging science in a contentious area.

Sex in City Plants, Animals, Fungi, and More: A Guide to Reproductive Diversity
by Kenneth D. FrankCities pose formidable obstacles to nonhuman life. Vast expanses of asphalt and concrete are inhospitable to plants and animals; traffic noise and artificial light disturb natural rhythms; sewage and pollutants imperil existence. Yet cities teem with life: In rowhouse neighborhoods, tiny flowers bloom from cracks in the sidewalk. White clover covers lawns, its seeds dispersed by shoes and birds. Moths flutter and spiders weave their webs near electric lights. Sparrows and squirrels feast on the scraps people leave behind. Pairs of red-tailed hawks nest on window ledges. How do wild plants and animals in urban areas find mates? How do they navigate the patchwork of habitats to reproduce while avoiding inbreeding? In what ways do built environments enable or inhibit mating?This book explores the natural history of sex in urban bacteria, fungi, plants, and nonhuman animals. Kenneth D. Frank illuminates the reproductive behavior of scores of species. He examines topics such as breeding systems, sex determination, sex change, sexual conflict, sexual trauma, sexually transmitted disease, sexual mimicry, sexual cannibalism, aphrodisiacs, and lost sex. Frank offers a guide to urban reproductive diversity across a range of conditions, showing how understanding of sex and mating furthers the appreciation of biodiversity. He presents reproductive diversity as elegant but vulnerable, underscoring the consequences of human activity. Featuring compelling photographs of a multitude of life forms in their city habitats, this book provides a new lens on urban natural history.
