Study and Design of Differential Microphone Arrays
Microphone arrays have attracted a lot of interest over the last few decades since they have the potential to solve many important problems such as noise reduction/speech enhancement, source separation, dereverberation, spatial sound recording, and source localization/tracking, to name a few. However, the design and implementation of microphone arrays with beamforming algorithms is not a trivial task when it comes to processing broadband signals such as speech. Indeed, in most sensor arrangements, the beamformer output tends to have a frequency-dependent response. One exception, perhaps, is the family of differential microphone arrays (DMAs) who have the promise to form frequency-independent responses. Moreover, they have the potential to attain high directional gains with small and compact apertures. As a result, this type of microphone arrays has drawn much research and development attention recently. This book is intended to provide a systematic study of DMAs from a signal processing perspective. The primary objective is to develop a rigorous but yet simple theory

for the design, implementation, and performance analysis of DMAs. The theory includes some signal processing techniques for the design of commonly used first-order, second-order, third-order, and also the general Nth-order DMAs. For each order, particular examples are given on how to form standard directional patterns such as the dipole, cardioid, supercardioid, hypercardioid, subcardioid, and quadrupole. The study demonstrates the performance of the different order DMAs in terms of beampattern, directivity factor, white noise gain, and gain for point sources. The inherent relationship between differential processing and adaptive beamforming is discussed, which provides a better understanding of DMAs and why they can achieve high directional gain. Finally, we show how to design DMAs that can be robust against white noise amplification.

Fisheries Management: A manual for still-water coarse fisheries by Ian Wellby
Fisheries Management is a beautifully-produced full colour guide to the management of still-water coarse fisheries. Carefully compiled by three leading specialists, who each draw on many years' experience, this book is an essential purchase for all still water coarse fisheries managers. The correct management of still waters and their fisheries is vital to ensure environmental protection and an appropriate level of stocking densities of healthy fish. This new book provides the reader with the necessary information to achieve these goals.
The book's first part covers the ecology of still waters and includes succinct and user-friendly information on physical and chemical processes, nutrient cycles, energy movements, trophic levels, bacteria, plants, invertebrates, fish, disease-causing organisms, mammals and birds.

Part two provides in depth, but easily assimilated cutting edge information, on how a still-water fishery should be set up, developed and successfully managed. Coverage includes development, preparation and construction; stock assessment and invertebrate survey; control of water quality, aquatic plants, erosion, predators and nuisance species; management of the impact of climate change; fish disease and biosecurity; control of fishing activities, fish nutrition, fishery enhancement and condition improvement, and general administration.

The final part of this excellent manual covers legal and social frameworks including general and environmental legislation, direct fisheries-related legislation, and agencies and organizations.

Fisheries Management provides fishery managers with an invaluable, practical tool which none should be without. Students studying fisheries biology, fisheries management and aquatic sciences will find this a very useful learning resource, as will all those who are considering buying or building and setting up lakes for fisheries. All libraries in universities, research establishments and government agencies where fisheries and biological sciences are studied and taught should have copies of this landmark publication on their shelves.

– Editor and authors with many years' practical experience
– Vital and commercially important information for fisheries managers
– A useful reference source for upper level students and academics
– Covers an important multi-million pound industry across many countries

Better Humans?: Understanding the Enhancement Project

Michael Hauskeller, "Better Humans?: Understanding the Enhancement Project"
English | ISBN: 1844655571, 1844655563 | 2013 | 240 pages | PDF | 13 MB

Better Humans?: Understanding the Enhancement Project
Developments in medical science have afforded us the opportunity to improve and enhance the human species in ways unthinkable to previous generations. Whether it's making changes to mitochondrial DNA in a human egg, being prescribed Prozac, or having a facelift, our desire to live longer, feel better and look good has presented philosophers, medical practitioners and policy-makers with considerable ethical challenges. But what exactly constitutes human improvement? What do we mean when we talk of making "better" humans? In this book Michael Hauskeller explores these questions and the ideas of human good that underpin them. Posing some challenging questions about the nature of human enhancement, he interrogates the logic behind its processes and examines the justifications behind its criteria. Questioning common assumptions about what constitutes human improvement, Hauskeller asks whether the criteria proposed by its advocates are convincing. The book draws on recent research as well as popular representations of human enhancement from advertising to the internet, and provides a non-technical and accessible survey of the issues for readers and students interested in the ethics and politics of human enhancement.

The Biological Foundations of Bioethics
Much recent thought on the ethics of new biomedical technologies, and work in ethics and political philosophy more generally, is committed to hidden and contestable views about the nature of biological reality. This selection of essays by Tim Lewens, a leading expert in the field, teases out these biological foundations of bioethical writing and subjects them to scrutiny. The topics covered include human enhancement, the risks of technical progress, the alleged moral threat of synthetic biology, the reality of human nature, the relevance of evolutionary psychology to social policy, the nature of the distinction between health and disease, and justice in healthcare decision-making.

Sacred Mushroom of Visions: Teonanácatl: A Sourcebook on the Psilocybin Mushroom by Ralph Metzner
English | July 25, 2005 | ISBN: 1594770441 | 293 Pages | PDF | 40,4 MB
"A compilation of scientific information, historical lore, and experiential reports about the magical psilocybe mushrooms. . . . It is sure to be treasured for years to come."
–Andrew Weil, M.D., author of The Natural Mind – A New Way of Looking at Drugs and the Higher Consciousness and Spontaneous Healing

"An outstanding comprehensive gathering of vital information from the psychedelic world."
–Myron Stolaroff, author of The Secret Chief and From Thanatos to Eros

Teonanácatl was the name given to the visionary mushrooms used in ancient Meso­american shamanic ceremonies, mushrooms that contain psilocybin, the psychoactive agent identified by Swiss chemist Albert Hofmann, the discoverer of LSD. The rediscovery of these visionary mushrooms by the Mazatec healer Maria Sabina and ­mycologist R. Gordon Wasson ignited a worldwide mushroom culture that inspired the consciousness revolution of the 1960s.

This book describes in vivid detail the consciousness-expanding experiences of psychoactive mushroom users–from artists to psychologists–and the healing visionary inspiration they received. It provides firsthand accounts of studies performed in the controversial Harvard Psilocybin Project, including the Concord Prison study and the Good Friday study. It describes how the use of the psilocybe mushroom spread from the mountains of Mexico into North America, Asia, and Europe by seekers of ­consciousness-­expanding experiences. It also details how psilocybin has been used since the 1960s in psychotherapy, prisoner rehabilitation, the enhancement of creativity, and the induction of mystical experiences and is being studied as a treatment for obsessive-compulsive disorder (OCD). In this book, over thirty contributors share their expertise on the chemical, biological, cultural, psychological, and experiential dimensions of psilocybin mushrooms.
