A teenage boy hunts for his mother’s killer in this Man Booker Prize-longlisted novel by “the true heir to the great Ruth Rendell” (Mail on Sunday, UK). Just before Jack’s mother disappeared up the road to get help, she put the eleven-year-old boy in charge of his two sister. As they wait for her on the shoulder of the road in their stifling, broken-down car, the three children bicker, whine and play I-Spy. But their mother never comes back. And after that long, hot summer’s day, nothing will ever be the same again. At fifteen-years-old, Jack is still in charge—supporting his sisters any way he can while evading social services. Meanwhile, a young woman across town wakes to find a knife beside her bed, and a note reading I could of killed you. The police are tracking a mysterious burglar they call Goldilocks, for his habit of sleeping in the beds of the houses he robs. But the woman doesn’t see the point of involving the police. And Jack, very suddenly, may be on the verge of finding out who killed his mother. The Gold Dagger Award-winning author of Blacklands reaffirms her reputation for masterful, twisty crime fiction with this “unnerving suspense novel” (Marilyn Stasio, The New York Times).

Don't just play computer games - help children build them with your own home computer! Calling all coders, this is a straightforward, visual guide to helping kids understand the basics of computer coding using Scratch and Python coding languages. Essential coding concepts like scripts, variables, and strings are explained using build-along projects and games. Kids can create online games to play like Monkey Mayhem and Bubble Blaster, draw mazes and shapes, build animations, and more using the step-by-step examples to follow and customize. Seven projects let kids (and their parents) practice the skills as they are learning in each section of the book. Kids get instant results, even when completely new to coding. Packed with visual examples, expert tips, a glossary of key terms, and extras such as profiles of famous coders, Help Your Kids with Computer Coding lays a hands-on foundation for computer programming, so adults and kids can learn together. Supporting STEM education initiatives, computer coding teaches kids how to think creatively, work collaboratively, and reason systematically, and is quickly becoming a necessary and sought-after skill. DK's computer coding books are full of fun exercises with step-by-step guidance, making them the perfect introductory tools for building vital skills in computer programming. User note: At home, all you need is a desktop or laptop with Adobe 10.2 or later, and an internet connection to download Scratch 2.0 and Python 3. Coding with Scratch can be done without download on https: //scratch.mit.edu. Series Overview: DK's bestselling Help Your Kids With series contains crystal-clear visual breakdowns of important subjects. Simple graphics and jargon-free text are key to making this series a user-friendly resource for frustrated parents who want to help their children get the most out of school.

Considers Space Nuclear Auxiliary Power program and plans for utilization of isotopic, reactor, or solar powered space electric power systems. Includes "Preliminary SNAPSHOT-1 Performance Summary," AEC report, p. 135-230.

The proper identification of fleas forms a sound basis for disease prevention and flea control. This publication, prepared primarily as a taxonomic revision, will help those called upon to identify the species of these insects and recommend control procedures. Full descriptions are given of the genera ad higher groups, accompanied in most instances by figures. For species, subspecies, and varieties formal descriptions are avoided, but data have usually been supplied for each as follows: Indication of synonymy, name of type host, type locality, statement relative to range, and remarks upon identification characteristics, nature of original description, references to figures, published notes on biology or economic importance, and redescriptions.

Advances in Nuclear Science and Technology, Volume 5 presents the underlying principles and theory, as well as the practical applications of the advances in the nuclear field. This book reviews the specialized applications to such fields as space propulsion. Organized into six chapters, this volume begins with an overview of the design and objective of the Fast Flux Test Facility to provide fast flux irradiation testing facilities. This text then examines the problem in the design of nuclear reactors, which is the analysis of the spatial and temporal behavior of the neutron and temperature distributions within the system. Other chapters consider the three major ways of estimating shield effectiveness. This book discusses as well the purpose of variational principle, which is a characterization of a function as the stationary point of an appropriate functional. The final chapter deals with the solution of the Boltzmann transport equation. This book is a valuable resource for engineers.
