If your dad is willing to save you from pirates, gorilla pirates, robot gorilla pirates and even robot gorilla pirates from Mars, you know he''ll do anything for you. And if that makes your dad hungry and thirsty or if he gets cuts and bruises, you know just how to take care of him right back. An adventurous tale of the heroic lengths fathers and sons will go for each other that will elicit gasps, giggles and warm contented sighs.

A bright and simple concept book takes readers through a noisy, smelly, sudsy, cluttered, and thoroughly enjoyable kitchen. "The dishwasher is loud. The counter is cluttered. The blender is noisy. The sandwich is cut. The bags are plastic. The milk is spilled. The popcorn is popping!" Through breakfast, lunch, dinner, and dessert, the kitchen is filled with interesting sights, smells, sounds and tastes. On this delicious trip through the kitchen, detail-rich scenes will delight young children as they recognize familiar foods and objects and learn new words to describe them. There''s lots of fun to be had in the room where the syrup is sticky, the candy is hidden and the pie is cherry!

A group of young trick-or-treaters demonstrate that "feet are for stomping, " "eyes are for peeking, " "mouths are for moaning, " and "tummies are for treating."

A simple presentation of a race car and how it is used and serviced during a race.

Flaps lift to reveal what different people, animals, or machines dig.

As he plays with his toy fire engine, a boy imagines himself fighting a real fire.

"In this comically far-fetched book, a talented gorilla’s paintings of other zoo animals and their visitors earn her fame and fortune, which she’s not sure what do with.... In the end, this joyful painting gorilla reminds us that the best things in life are free." --Publishers Weekly

Previous investigations of oscillating (harmonic) flow past circular cylinders via the discrete vortex method have met with limited success due to a variety of reasons. These assumptions have proven to be too severe, and cannot allow the prediction of the kinematics and dynamics of the oscillating flow about bluff bodies in general and about a circular cylinder in particular. In the current analysis, the ambient velocity was given by U = Um sin wt, and the velocity distribution and the boundary layer were calculated about the cylinder at suitable time intervals. Several methods were implemented to predict separation, all of which required a minimum of arbitrary assumptions. Nascent vortices were placed at the separation points in such a manner that the Kutta condition was satisfied. Several functional forms of dissipation were investigated, but it was found not to be of overriding influence in the flow kinematics. Counter vortices were found to be a necessary aspect of the analysis, providing continuity from one half cycle to the next. Flow visualization experiments were conducted for a Keulegan-Carpenter number of 10 as a basis for comparison. The kinematics obtained from the numerical model produced a vortex shedding pattern which was typical of those observed experimentally for higher Keulegan-Carpenter numbers. Significant problems were encountered in the prediction of boundary layer separation. At this point, it was obvious that the interaction of a vortex with a boundary layer warranted analysis in a much simpler flow situation; the blade-vortex interaction (BVI) problem proved to be ideal.

The technique of plastic design has many advantages over the traditional elastic design technique. With the publication of this book, American designers and engineers will be given easy access to the latest developments in the theory and practice of plastic design.
