Times are tough for shrimpers and fishers in the Gulf of Mexico. The animals they rely on for their livelihood are harder to find. Every summer a dead zone—a region of low oxygen—emerges in the waters along the Gulf Coast. Where oxygen is low, fish and others animals cannot survive. Currently the world has more than 400 identified dead zones, up dramatically from the 49 dead zones identified in the 1960's.The good news is that people can eliminate dead zones by changing agricultural practices and reducing pollution. Using real-world examples, this book looks at the impact of pollution on global water resources, and discusses the interconnectedness of ecosystems and organisms.

Dead zones are on the rise... Human activity has caused an increase in uninhabitable, oxygen-poor zones--also known as "dead zones"--in our waters. Oxygen is the third most abundant element in the universe, and it is a necessity for nearly all life on Earth. Yet many rivers, estuaries, coastal waters, and parts of the open ocean lack enough of it. In this book, David L. Kirchman explains the impacts of dead zones and provides an in-depth history of oxygen loss in water. He details the role the agricultural industry plays in water pollution, showcasing how fertilizers contaminate water supplies and kickstart harmful algal blooms in local lakes, reservoirs, and coastal oceans. Algae decomposition requires so much oxygen that levels drop low enough to kill fish, destroy bottom-dwelling biota, reduce biological diversity, and rearrange food webs. We can't undo the damage completely, but we can work together to reduce the size and intensity of dead zones in places like the Gulf of Mexico, Chesapeake Bay, and the Baltic Sea. Not only does Kirchman clearly outline what dead zones mean for humanity, he also supplies ways we can reduce their deadly impact on human and aquatic life. Nutrient pollution in some regions has already begun to decline because of wastewater treatment, buffer zones, cover crops, and precision agriculture. More needs to be done, though, to reduce the harmful impact of existing dead zones and to stop the thousands of new ones from cropping up in our waters. Kirchman provides insight into the ways changing our diet can reduce nutrient pollution while also lowering greenhouse gasses emitted by the agricultural industry. Individuals can do something positive for their health and the world around them. The resulting book allows readers interested in the environment--whether students, policymakers, ecosystem managers, or science buffs--to dive into these deadly zones and discover how they can help mitigate the harmful effects of oxygen-poor waters today.

The #1 New York Times bestseller and “compulsive page-turner” (The Atlanta Journal-Constitution) about a reluctant clairvoyant man who must weigh his options when he suddenly sees the terrible future awaiting mankind—from master storyteller Stephen King. When Johnny Smith was six years old, head trauma caused by a bad ice-skating accident left him with a nasty bruise on his forehead and, from time to time, those hunches…infrequent but accurate snippets of things to come. But it isn’t until Johnny’s a grown man—now having survived a horrifying auto injury that plunged him into a coma lasting four-and-a-half years—that his special abilities really push to the fore. Johnny Smith comes back from the void with an extraordinary gift that becomes his life’s curse…presenting visions of what was and what will be for the innocent and guilty alike. But when he encounters a ruthlessly ambitious and amoral man who promises a terrifying fate for all humanity, Johnny must find a way to prevent a harrowing predestination from becoming reality.

'An honest, compelling and important account, and a critical plea for a fusion of farming, food and nature to provide global ecological security' CHRIS PACKHAM Why are so many animals facing extinction? Climate change and poaching are not the only culprits. The impact of consumer demand for cheap meat is equally devastating, and it is vital that we confront this problem if we are to stand a chance of reducing its effect on the world around us. · We are falsely led to believe that squeezing animals into factory farms and cultivating crops in vast, chemical-soaked prairies is a necessary evil, an efficient means of providing for an ever-expanding global population while leaving land free for wildlife · Our planet's resources are reaching breaking point: awareness is slowly building that the wellbeing of society depends on a thriving natural world From the author of the internationally acclaimed Farmageddon, Dead Zone takes us on an eye-opening journey across the globe, focussing on a dozen iconic species - from elephants to bumblebees to penguins - and looking at the role that industrial farming is playing in their plight.

Sigma delta modulation has become a very useful and widely applied technique for high performance Analog-to-Digital (A/D) conversion of narrow band signals. Through the use of oversampling and negative feedback, the quantization errors of a coarse quantizer are suppressed in a narrow signal band in the output of the modulator. Bandpass sigma delta modulation is well suited for A/D conversion of narrow band signals modulated on a carrier, as occurs in communication systems such as AM/FM receivers and mobile phones. Due to the nonlinearity of the quantizer in the feedback loop, a sigma delta modulator may exhibit input signal dependent stability properties. The same combination of the nonlinearity and the feedback loop complicates the stability analysis. In Bandpass Sigma Delta Modulators, the describing function method is used to analyze the stability of the sigma delta modulator. The linear gain model commonly used for the quantizer fails to predict small signal stability properties and idle patterns accurately. In Bandpass Sigma Delta Modulators an improved model for the quantizer is introduced, extending the linear gain model with a phase shift. Analysis shows that the phase shift of a sampled quantizer is in fact a phase uncertainty. Stability analysis of sigma delta modulators using the extended model allows accurate prediction of idle patterns and calculation of small-signal stability boundaries for loop filter parameters. A simplified rule of thumb is derived and applied to bandpass sigma delta modulators. The stability properties have a considerable impact on the design of single-loop, one-bit, high-order continuous-time bandpass sigma delta modulators. The continuous-time bandpass loop filter structure should have sufficient degrees of freedom to implement the desired (small-signal stable) sigma delta modulator behavior. Bandpass Sigma Delta Modulators will be of interest to practicing engineers and researchers in the areas of mixed-signal and analog integrated circuit design.

After a worldwide zombie apocalypse caused the near extinction of the human race in 2012, the rural Kentucky city of Elizabethtown was transformed into a fortress for humanity thanks to the combined efforts of survivors from the region. Taking the name Live E-town, this survivor enclave stood up a force of contracted Zombie Killers to protect itself. Known as ZKs, these resourceful mercenaries defend Live E-town's borders and make war on the undead and human raider bands that inhabit the dangerous Dead Zones that surround them. By 2014, Live E-town's ZKs are the dominant living force in the Dead Zones in a hundred mile radius. Their offensive operations have pushed a perimeter out five miles into the farmland surrounding the town, diverted and exterminated scores of undead herds, suppressed most of the raider groups, rescued thousands of survivors, and recovered hundreds of tons of survival critical resources. Live E-town is a beacon of hope for mankind's continued existence but survival remains a daily battle, the outcome of which has yet to be determined. The war to take the world back from the undead is only in its initial engagements. Essays From The Dead Zone is a guide for offensive operations against the undead written by a pragmatic, knowledgeable, combatant. It originally appeared in Live E-town in late 2014 as Zombie Killer Handbook, a training manual for new recruits to the contract ZK force. It is a collection of essays on ZK equipment, weapons, tactics, missions and threats in the Dead Zones. It is heavily illustrated with photographs from actual operations. The essays are all reluctantly authored by a famed, and perhaps infamous, ZK captain called Soo-Z. She is in charge of the ZKs stationed at Outpost #7 on the eastern perimeter of the town and is as much feared as respected. Soo-Z gets to the crux of matters quickly with experience based know-how, authority and surprising humor. Beyond her fascinatingly detailed accounts of the ZKs' harrowing work in the Dead Zones, the essays give the reader a glimpse of the sensibilities and values of a post-apocalyptic survivor turned warrior.

This book employs the powerful and popular adaptive backstepping control technology to design controllers for dynamic uncertain systems with non-smooth nonlinearities. Various cases including systems with time-varying parameters, multi-inputs and multi-outputs, backlash, dead-zone, hysteresis and saturation are considered in design and analysis. For multi-inputs and multi-outputs systems, both centralized and decentralized controls are addressed. This book not only presents recent research results including theoretical success and practical development such as the proof of system stability and the improvement of system tracking and transient performance, but also gives self-contained coverage of fundamentals on the backstepping approach illustrated with simple examples. Detail description of methodologies for the construction of adaptive laws, feedback control laws and associated Lyapunov functions is systematically provided in each case. Approaches used for the analysis of system stability and tracking and transient performances are elaborated. Two case studies are presented to show how the presented theories are applied.
