This innovative edited collection brings together leading international academics to explore the use of various non-prescription and prescription substances. From a psychosocial perspective, the authors discuss the complex reasons behind their adoption, the ways in which they are misused, and links between use and cognitive enhancement. While studies on substance use to date have examined the aetiology and effects in the context of sporting performance, addiction and recreational use, there has been little work which explores their wider misuse to improve cognitive enhancement. With medical sociology and social psychology at its core, this important volume shows the complex reasons behind the misuse of various substances, how these are connected to contemporary desire for increased mental performance, and why the potential health risks and possibly harmful side effects do not act as deterrents.
This comprehensive Monograph examines all peripheral and central mechanisms of regulating the secretion of milk from the lactating breast. The author reviews the complete female breast development, starting with the early childhood, up to pregnancy and lactation. Structural and ultrastructural data on the alveolar-ductal system, together with details of breast innervation, are used to investigate the physiological process of lactation. Readers will appreciate the special focus on reflexes, both in the child and the mother, that help to regulate maternal milk production and secretion. Following this, the author sheds a light on the composition and dynamics of milk components during the different periods of lactation. The final section of this volume focusses on practical aspects of modern breastfeeding, like the use of breast pumps or galactogogues, to influence the productivity of milk production. These fundamental principles and structural details will be particularly useful for physiologists and clinicians working in gynecology and pediatrics.
Human sexual nature today experiences many unanswered questions. Why does woman respond more slowly than man in arousal? What is the significance of the human orgasm? Why does sexual experience so often fail to form a lasting relationship? When is the most vulnerable time for a relationship in the process of formation? These and other questions are supported to find answers in our evolutional history. In this wide ranging and penetrating study the author finds human sexual nature to be basically inclined to committed relationships. The deepest evolutional trend, having early vertebrate origins, he finds to be the increasing biological investment in the unit young of each new generation.
Pollution doesn't make for easy sonnets or flowing, romantic narratives. And that's what this title is about - pollution. Not the everyday sort of pollution that we recognise so easily, the type which piles up into stinking heaps of litter or that clogs the sky with filthy smoke. No, this is a form of pollution which is so subtle and insidious that many people do not realise it is there. Invaded is about biological pollution, the kind that comes in dense hedges of lush greenery, blooming fields of heady petals or gracefully draped creepers. It may spread incognito on the wings of a bird, tug on the end of an angler's line or scurry unnoticed through the undergrowth. These pages explore plants and animals that have traversed the borders and boundaries of their natural habitats and made their way into South Africa over the past 300 years and more. Unhindered by the predators and diseases which once kept their populations in check, many have come to outnumber and out-compete the species they encounter in their adopted homes. Invaded provides an overview of the different species that have arrived in our country during the past three centuries, and the threats they pose (or have the potential to become). Ultimately, the book attempts to quantify how these species have changed systems, disrupted the natural environment and threatened the future of the country's many unique plants, animals and habitats.

The study of ecosystems, fundamental to ecology, has been complemented by the growing field of landscape ecology. Ecosystem Function in Heterogeneous Landscapes addresses how interactions among ecosystems affect the functioning of individual ecosystems and the larger landscape. This groundbreaking synthesis unites ecosystem ecology's knowledge of system function with landscape ecology's knowledge of spatial structure. Practical concerns about scaling up from individual ecosystems to larger landscapes require an understanding of how networks of interacting ecosystems function together. The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management. The distinguished authors discuss how how much heterogeneity needs to be taken into account for specific types of scientific and management issues. Their chapters cover the spectrum from proposing novel conceptual approaches to detailing the practical implications of heterogeneous landscapes for fire management, water management and conservation planning.
Intertidal mudflats are distinct, highly-productive marine habitats which provide important ecosystem services to the land-sea interface. In contrast to other marine habitats, and despite a large body of primary scientific literature, no comprehensive synthesis exists, such that the scattered knowledge base lacks an integrated conceptual framework. We attempt to provide this synthesis by pulling together and contextualizing the different disciplines, tools, and approaches used in the study of intertidal mudflats. The editor pays particular attention to relationships between the various components of the synthesis, both at the conceptual and the operational levels, validating these relationships through close interaction with the various authors.
This book looks at how three kinds of strongly electric fishes
literally became "electrical," and how they helped to change the
sciences and medicine. These fishes are the flat torpedo rays
common to the Mediterranean, the electric catfishes of Africa, and
an "eel" from South America. The discovery of the electrical nature
of these fishes in the second half of the 18th century was the
starting point of the two fundamental advances in the sciences: on
the physiological side, the demonstration that nerve conduction and
muscle excitation are electrical phenomena, and on the physical
side, the invention of the electric battery. Starting with catfish
tomb drawings from Ancient Egypt and colorful descriptions of
torpedoes from the Classical Era, the authors show how these fishes
were both fascinating and mysterious to the ancients. After all,
not only could they produce torpor and temporary numbness when
touched, they could stun through intermediaries, such as wet nets
and spears.
Ecometabolomics: Metabolic Fluxes versus Environmental Stoichiometry focuses on the interaction between plants-particularly plants that have vigorous secondary metabolites-and the environment. The book offers a comprehensive overview of the responses of the metabolome of organisms to biotic and abiotic environmental changes. It includes an introduction to metabolomics, summaries of metabolomic techniques and applications, studies of stress in plants, and insights into challenges. This is a must-have reference for plant biologists, plant biochemists, plant ecologists and phytochemists researching the interface between plants and the environment using metabolomics.

Given that sustainability has many faces and facets, it is worthwhile to deal with the relation (or impact) of COVID-19 on various elements of sustainability. This book presents how COVID-19 has influenced waste management and air quality.
The aim of this book is not only to introduce readers with a broad spectrum of biological actions of the NOP receptor, but also to feature a detailed look at the N/OFQ-NOP receptor system, medicinal chemistry, pharmacology, and clinical data of NOP-targeted ligands. This special volume book - for the first time focusing on the NOP receptor - is designed to serve as a useful reference, stimulate more research on the N/OFQ-NOP receptor system, and lead to more development of NOP-related ligands for several therapeutic applications.
The principal objective of this book is to provide information needed to define human thermal behavior quantitatively. Human thermal physiology is defined using mathematical methods routinely employed by physicists and engineers, but seldom used by physiologists. Major sections of the book are devoted to blood flow, sweating, shivering, heat transfer within the body, and heat and mass transfer from skin and clothing to the environment. Simple algebraic models based on experimental data from a century of physiological investigation are developed for bodily processes. The book offers an invaluable source of information for physiologists and physical scientists interested in quantitative approaches to the fascinating field of human thermoregulation.
This book provides an up-to-date review and analysis of the carrot's nuclear and organellar genome structure and evolution. In addition, it highlights applications of carrot genomic information to elucidate the carrot's natural and agricultural history, reproductive biology, and the genetic basis of traits important in agriculture and human health. The carrot genome was sequenced in 2016, and its relatively small diploid genome, combined with the fact that it is the most complete root crop genome released to date and the first-ever Euasterid II genome to be sequenced, mean the carrot has an important role in the study of plant development and evolution. In addition, the carrot is among the top ten vegetables grown worldwide, and the abundant orange provitamin A carotenoids that account for its familiar orange color make it the richest crop source of vitamin A in the US diet, and in much of the world. This book includes the latest genetic maps, genetic tools and resources, and covers advances in genetic engineering that are relevant for plant breeders and biologists alike.

Revealing the famous scientist's life in compelling detail, Darwin covers not only his scientific career and On the Origin of Species but his personal struggles also, allowing us to see what truly made the man.
This book on wetlands ecosystems in Asia deals with function and management. It is the first volume in the Developments in Ecosystems series.
Nowhere on Earth is the challenge for ecological understanding greater, and yet more urgent, than in those parts of the globe where human activity is most intense - cities. People need to understand how cities work as ecological systems so they can take control of the vital links between human actions and environmental quality, and work for an ecologically and economically sustainable future. An ecosystem approach integrates biological, physical and social factors and embraces historical and geographical dimensions, providing our best hope for coping with the complexity of cities. This book is the first of its kind to bring together leaders in the biological, physical and social dimensions of urban ecosystem research with leading education researchers, administrators and practitioners, to show how an understanding of urban ecosystems is vital for urban dwellers to grasp the fundamentals of ecological and environmental science, and to understand their own environment.
This book focuses on the spatial distribution of landslide hazards of the Darjeeling Himalayas. Knowledge driven methods and statistical techniques such as frequency ratio model (FRM), information value model (IVM), logistic regression model (LRM), index overlay model (IOM), certainty factor model (CFM), analytical hierarchy process (AHP), artificial neural network model (ANN), and fuzzy logic have been adopted to identify landslide susceptibility. In addition, a comparison between various statistical models were made using success rate cure (SRC) and it was found that artificial neural network model (ANN), certainty factor model (CFM) and frequency ratio based fuzzy logic approach are the most reliable statistical techniques in the assessment and prediction of landslide susceptibility in the Darjeeling Himalayas. The study identified very high, high, moderate, low and very low landslide susceptibility locations to take site-specific management options as well as to ensure developmental activities in theDarjeeling Himalayas. Particular attention is given to the assessment of various geomorphic, geotectonic and geohydrologic attributes that help to understand the role of different factors and corresponding classes in landslides, to apply different models, and to monitor and predict landslides. The use of various statistical and physical models to estimate landslide susceptibility is also discussed. The causes, mechanisms and types of landslides and their destructive character are elaborated in the book. Researchers interested in applying statistical tools for hazard zonation purposes will find the book appealing.
This book addresses multiple aspects of biological clocks in prokaryotes. The first part of the book deals with the circadian clock system in cyanobacteria, i.e. the pioneer of bacterial clocks. Starting with the history and background of cyanobacteria and circadian rhythms in microorganisms, the topics range from the molecular basis, structure and evolution of the circadian clock to modelling approaches, Kai systems in cyanobacteria and biotechnological applications. In the second part, emergent timekeeping properties of bacteria in microbiomes and bacteria other than cyanobacteria are discussed. Since the discovery of circadian rhythms in cyanobacteria in the late 1980s, the field has exploded with new information. The cyanobacterial model system for studying circadian rhythms (Synechococcus elongatus), has allowed a detailed genetic dissection of the bacterial clock due to state-of-the-art methods in molecular, structural, and evolutionary biology. Cutting-edge research spanning from cyanobacteria and circadian phenomena in other kinds of bacteria, to microbiomes has now given the field another major boost. This book is aimed at junior and senior researchers alike. Students or researchers new to the field of biological clocks in prokaryotes will get a comprehensive overview, while more experienced researchers will get an update on the latest developments. |
