Power Supplies for LED Driving
Light-emitting diodes are being widely used due to their efficient use of power. The applications for power LEDs include traffic lights, street lamps, automotive lighting, architectural lights, household light replacements, signage lighting (replacing neon strip lights and fluorescent tubes), and many more. Powering (driving) these LED's is not always simple. Linear driving is inefficient and generates far too much heat. With a switching supply, the main issues are EMI and efficiency, and of course cost. The problem is to get a design that meets legal requirements and is efficient, while costing the least. This book covers the design trade-offs involved in LED driving applications, from low-power to UB-LEDs and beyond. * Practical, "hands-on" approach to power supply design for LED drivers; * Detailed examples of what works and why, throughout the design process; * Commentary on how the calculated component value compares with the actual value used, including a description of why the choice was made.
Cell Death
Poly (ADP-ribose) polymerase (PARP), also termed poly (ADP-ribose) synthetase (PARS) is a nuclear enzyme with a wide range of functions, including regulation of DNA repair, cell differentiation, and gene expression. More than a decade after the identification of PARP-like enzymatic activities in mammalian cells, a novel role was proposed for this e
Fangless
Fangless: Book One by Evelyn Fangless: Book One is about a young smilodon named Fangless. Fangless was born at “the Place of Thin Ice,” a well known place named for the thin layers of ice that cover the deep, icy waters below. After receiving a dream given by Shashthi, the smilodon kit goddess, Fangless’ mother, May-Paw, must follow Shashthi’s instructions to give birth to Fangless at the Place of Thin Ice. If not, Fangless will meet a certain terrible fate, followed shortly after by death itself. Soon after May-Paw’s kit’s birth, the ice breaks under both her and Fangless’ paws. He is swept out into the icy waters aboard a drifting sheet of ice, but miraculously survives his nightmare of a journey and is then pushed ashore. Fangless is found by an ex-mother smilodon named Flower who left her bloodthirsty clan after her cruel ex-leader named Asesino murdered her only kit for being blind and weak – an outcast. Flower takes Fangless under her care and protection naming him “Fangless” because he was born without fangs, thus making him an outcast as well.
Wizard's Bane
Wizard's Bane is the first book of The Sojourn Chronicles, six books that recount the adventures of Dale, a member of a large space fleet, who is marooned on a world similar to 18th-century Earth. He discovers very quickly that being stranded is the least of his problems; the world he is on is about to be destroyed and he's the only one that can save it. Without any clear direction, or the tools to do so, he sets out to try, encountering magic, mayhem and chaos at every turn. Wizard's Bane has received rave reviews and even been compared to the Shadow Trilogy by George Lucas.

Shale is befriended by Mulie, a mountain man. They are accused of rustling and almost hung. After arriving in Stonebluff, they learn that Shale’s uncle has been killed. Shale is sentenced to prison on a trumped-up robbery charge and escapes en route. He helps an Indian boy and takes him back to his Comanche camp and spends the winter. When the snow clears, Shale rides back to clear his name.
Urban and Transit Planning
This book incorporates a wealth of research focused on the more and more urgent challenges that urban planning and architectural design all over the world must cope with: from climate change to environmental decay, from an increasing urban population to an increasing poverty. In detail, this book aims at providing innovative approaches, tool and case study examples that, in line with the agenda of 2030, may better drive human settlements toward a sustainable, inclusive and resilient development. To this aim, the book includes heterogeneous regional perspectives and different methodologies and suggests development models capable of limiting further urban growth and re-shaping existing cities to improve both environmental quality and the overall quality of life of people, also taking account the more and more close relationships among urban planning and technological innovation.
