Originating from models of biological neural systems, artificial neural networks (ANN) are the cornerstones of artificial intelligence research. Catalyzed by the upsurge in computational power and availability, and made widely accessible with the co-evolution of software, algorithms, and methodologies, artificial neural networks have had a profound impact in the elucidation of complex biological, chemical, and environmental processes. Artificial Neural Networks in Biological and Environmental Analysis provides an in-depth and timely perspective on the fundamental, technological, and applied aspects of computational neural networks. Presenting the basic principles of neural networks together with applications in the field, the book stimulates communication and partnership among scientists in fields as diverse as biology, chemistry, mathematics, medicine, and environmental science. This interdisciplinary discourse is essential not only for the success of independent and collaborative research and teaching programs, but also for the continued interest in the use of neural network tools in scientific inquiry. The book covers: A brief history of computational neural network models in relation to brain function Neural network operations, including neuron connectivity and layer arrangement Basic building blocks of model design, selection, and application from a statistical perspective Neurofuzzy systems, neuro-genetic systems, and neuro-fuzzy-genetic systems Function of neural networks in the study of complex natural processes Scientists deal with very complicated systems, much of the inner workings of which are frequently unknown to researchers. Using only simple, linear mathematical methods, information that is needed to truly understand natural systems may be lost. The development of new algorithms to model such processes is needed, and ANNs can play a major role. Balancing basic principles and diverse applications, this text introduces newcomers to the field and reviews recent developments of interest to active neural network practitioners.
This edited volume provides a biosemiotic analysis of the ecological relationship between food and medicine. Drawing on the origins of semiotics in medicine, this collection proposes innovative ways of considering aliments and treatments. Considering the ever-evolving character of our understanding of meaning-making in biology, and considering the keen popular interest in issues relating to food and medicines - fueled by an increasing body of interdisciplinary knowledge - the contributions here provide diverse insights and arguments into the larger ecology of organisms' engagement with and transformation through taking in matter. Bodies interpret molecules, enzymes, and alkaloids they intentionally and unintentionally come in contact with according to their pre-existing receptors. But their receptors are also changed by the experience. Once the body has identified a particular substance, it responds by initiating semiotic sequences and negotiations that fulfill vital functions for the organism at macro-, meso-, and micro-scales. Human abilities to distill and extract the living world into highly refined foods and medicines, however, have created substances far more potent than their counterparts in our historical evolution. Many of these substances also lack certain accompanying proteins, enzymes, and alkaloids that otherwise aid digestion or protect against side-effects in active extracted chemicals. Human biology has yet to catch up with human inventions such as supernormal foods and medicines that may flood receptors, overwhelming the body's normal satiation mechanisms. This volume discusses how biosemioticians can come to terms with these networks of meaning, providing a valuable and provocative compendium for semioticians, medical researchers and practitioners, sociologists, cultural theorists, bioethicists and scholars investigating the interdisciplinary questions stemming from food and medicine.
Green chemistry involves designing novel ways to create and synthesize products and implement processes that will eliminate or greatly reduce negative environmental impacts. The Green Chemistry Laboratory Manual for General Chemistry provides educational laboratory materials that challenge students with the customary topics found in a general chemistry laboratory manual, while encouraging them to investigate the practice of green chemistry. Following a consistent format, each lab experiment begins with objectives and prelab questions highlighting important issues that must be understood prior to getting started. This is followed by detailed step-by-step procedures for performing the experiments. Students report specific results in sections designated for data, observations, and calculations. Once each experiment is completed, analysis questions test students comprehension of the results. Additional questions encourage inquiry-based investigations and further research about how green chemistry principles compare with traditional, more hazardous experimental methods. By placing the learned concepts within the larger context of green chemistry principles, the lab manual enables students to see how these principles can be applied to real-world issues. Performing laboratory exercises through green experiments results in a safer learning environment, limits the quantity of hazardous waste generated, and reduces the cost for chemicals and waste disposal. Students using this manual will gain a greater appreciation for green chemistry principles and the possibilities for future use in their chosen careers.
A complete introduction to environmental chemistry, this book provides insight into the operation of the chemical processes near the Earth's surface. The four-part format groups together related environmental topics and introduces theoretical concepts.

This open access book deals with global sanitation, where SDG 6.2 sets a target of enabling access to sanitation services for all, but has not yet been achieved in low- and middle-income countries. The transition from the United Nations MDGs to the SDGs requires more consideration based on the socio-cultural aspects of global sanitation. In other words, equitable sanitation for those in vulnerable situations could be based on socio-cultural contexts. Sanitation is a system that comprises not only a latrine but also the works for the treatment and disposal of human waste. Sanitation systems do not function by themselves but have significance only through social management. The process of decision-making also largely depends on socio-cultural conditions, and the importance of sanitation needs to be socially acknowledged. The health benefits of sanitation improvement-among the significant contributions of sanitation-also need to be considered in the socio-cultural milieu. Further, the social-culture itself is affected, and potentially even created, by sanitation. In this context, more progress on the improvement of sanitation requires a more holistic approach across disciplines. In this book, we present the concept of the Sanitation Triangle, which considers the interconnections of health, materials, and socio-culture in sanitation, as a holistic approach, and the case studies based on the Sanitation Triangle by diverse disciplines such as Cultural Anthropology, Development Studies, Health Sciences, Engineering, and Science Communication. By the deep theoretical examinations and inter-dialogues between the different disciplines, this book explores the potentialities of inter-disciplinary studies on global sanitation.

Written by Dr. Ronald Eisler, a noted authority on chemical risk assessment, the book summarizes real and projected effects of oceanic acidification.
Environmental Fate and Transport Analysis with Compartment Modeling explains how to use the powerful, highly flexible, and intuitive compartment approach to estimate the distribution of chemical contaminants in environmental media in time and space. Add this Easy-to-Use Approach to Your Environmental Modeling Toolbox This numerical technique enables readers to easily develop the equations that describe complex environmental problems by assembling the equations out of compartmental building blocks. The compartments may describe spatial subunits of single- or multi-environmental media, and the way one hooks them together implicitly provides the dimensionality of the problem. With this approach, assembling the equations to describe chemical fate and transport in a three-dimensional, multimedia system is fundamentally no more challenging than a one-dimensional, single-medium problem. Go Beyond "Black Box" Modeling with the Flexible GEM Software The book includes access to the Generic Environmental Model (GEM), a new software package developed by the author. This software implements the compartment approach based on user-prepared input files and solves the resulting mathematical equations. It allows readers to solve linear, nonlinear, and steady-state problems and offers four methods for solving dynamic problems. Each solution technique is reviewed, along with the error properties and the criteria for avoiding or minimizing numerical errors. The book also describes solution techniques and the underlying mathematical theory for solving nonlinear systems. Compartment Modeling from the Ground Up, Made Accessible to Non-Mathematicians A user-friendly introduction to environmental compartment modeling for the beginning modeler, this is also a useful resource for the experienced modeler. It combines a reference on compartment modeling with a user's guide to the GEM. Throughout, the GEM is used to illustrate the theory with numerous examples, while the theoretical discussions illuminate the GEM's functionality.
