For the big, grownup boys out there, the potty masters in training, You Can't Wear Underpants! is a cry (the big-boy kind!) of toilet triumph and persevering underpants pride. Each turn of the page reveals an infant, animal, toy or other object obviously not suited for big-boy underpants: "No... YOU can't wear underpants!" Each facing page beams with the brilliance of a self-proud, underpant-wearing hero: "I wear big-boy underpants!" Underpants-wearer or not, all readers will be singing and rejoicing in the household's new mantra—all day long! You Can't Wear Underpants! is a perfect companion to the potty training process at all stages, serving up read-aloud, chant-along fun and motivation, inspiring even the most reluctant to join the celebration and excitement of dropping the diapers and embracing the BIG boy underpants and true toilet independence.Ver libro
The final book in the contemporary fantasy trilogy set in Dublin: and Dubh Linn, the fae world that exists in the cracks and corners of reality. Angels, fae demons and humans are drawn into lethal conflict as the fate of the world hangs in the balance in the final installment in this urban fantasy. Holly, the fae matriarch, tries to sieze the power of heaven for herself, while Izzy has lost her memory and Jinx is dead ... or is he? Confronted with ancient powers, sacrifice and treachery. War is looming within the ranks of the Sidhe. The angels and the demons begin to draw lines, daring each other to transgress and start another war ... 'fantasy lovers will adore the twists and turns … it's wonderful to see Irish mythology in the hands of someone who knows what they're talking about and resists presenting the reader with a twee view of the country' Inis Magazine about A Crack in EverythingVer libro

A fantastic kid's spy adventure set in a secret agent training school - Similar to the Alex Rider series - Irish-based but with a host of international characters and settings - Author of the Penny the Pencil series for younger readers Fourteen-year-old Jess Leclair is an exceptional teenager: athletically gifted and academically brilliant. Bored at her conventional Dublin school, she is thrilled to be offered a place at PEP Academy, the training ground for the top-secret PEP (Planet Earth Protection) Squad. During her first term, Jess quickly makes friends with her roommate, extreme-sport-loving Emily Harris, and the Sykes twins, Ben and Matt. Together, they learn the skills they will need to become world-class spies, like lock-picking, making disguises, abseiling, foreign languages and combat training. The teenagers are promised an easy first mission at the end of their first year. But then they find out they must infiltrate a Bavarian castle and steal a sample of a deadly virus that could wipe out all of humanity. Faced with armed guards, a complex security system, an evil genius and a traitor, the trainee spies must save the day or die trying. This is the next big thing in adventure fiction for pre-teens!Ver libro

The book is divided to different learning partsPart 1- Apply basic physical concepts to explain the operation and solve problems related to electrical machines.Part 2- Explain the principles underlying the performance of three-phase electrical machines.Part 3- Analyse, operate and test three-phase induction machines.Part 4- Investigate the performance, design, operation, and testing of the three-phase synchronous machine.Part1: Apply basic physical concepts to explain the operation and solve problems related to electrical machines.Describe the construction of simple magnetic circuits, both with and without an air gap. Explain the basic laws which govern the electrical machine operation, such as Faraday's Law, Ampere-Biot-Savart's Law, and Lenz's Law. Apply Faraday's Law of electromagnetic induction, Ampere-Biot-Savart's Law, and Lenz's Law to solve for induced voltage and currents in relation to simple magnetic circuits with movable parts. Illustrate the principle of the electromechanical energy conversion in magnetic circuits with movable parts.Part 2: Explain the principles underlying the performance of three-phase electrical machines. Compare and contrast concentric and distributed windings in three-phase electrical machines. Identify the advantages of distributed windings applied to three-phase machines. Explain how the pulsating and rotating magnetic fields are produced in distributed windings. Calculate the synchronous speed of a machine based on its number of poles and frequency of the supply. Describe the process of torque production in multi-phase machines.Part 3: Analyse, operate and test three-phase induction machines. Calculate the slip of an induction machine given the operating and synchronous speeds. Calculate and compare between different torques of a three-phase induction machine, such as the locked rotor or starting torque, pull-up torque, breakdown torque, full-load torque or braking torque. Develop and manipulate the equivalent circuit model for the three-phase induction machine. Analyse, and test experimentally, the torque-speed and current-speed characteristics of induction machines. and discuss the effects of varying such motor parameters as rotor resistance, supply voltage and supply frequency on motor torque-speed characteristics. Perform no-load and blocked rotor tests in order to determine the equivalent circuit parameters of an induction machine. Explore various techniques to start an induction motor. Identify the applications of the three-phase induction machines in industry and utility. Classify the insulations implemented in electrical machines windings and identify the factors affecting them. Part4. Investigate the performance, design, operation, and testing of the three-phase synchronous machine. Describe the construction of three-phase synchronous machines, particularly the rotor, stator windings and the rotor saliency. Develop and manipulate an equivalent circuit model for the three-phase synchronous machine. Sketch the phasor diagram of a non-salient poles synchronous machine operating at various modes operation, such as no-load operation, motor operation, and generator operation. Investigate the influence of the rotor saliency on machine performance. Perform open and short circuit tests in order to determine the equivalent circuit parameters of a synchronous machine. Identify the applications of the three-phase synchronous machines in industry and utility List and explain the conditions of parallel operation of a group of synchronous generators. Evaluate the performance of the synchronous condenser and describe the power flow control between a synchronous condenser and the utility in both modes: over and under excited. Explain the principles of controlling the output voltage and frequency of a synchronous generator.Ver libro
The classic children’s folktale of the Gingerbread Boy gets a spicy Cajun twist—and comes with a delicious recipe for cornbread. Down on the bayou in the heart of Cajun country lives a little old woman who is very lonely. One day, she decides to make a cornbread boy. Taking down her grandmère’s magical black iron skillet, she adds all the right ingredients, careful not to forget a big dash of cayenne pepper. When the cornbread boy pops out of the oven, he blinks his chili-pepper eyes, sprouts arms and legs, and sprints out the door before the old woman can catch him. Through the swamp and past the creatures curiously sniffing after him, the cornbread boy runs until he meets an artful alligator who is in for one spicy surprise. In this flavorful retelling of the classic Gingerbread Boy tale, international storyteller extraordinaire Dianne de Las Casas presents a delightful romp through Cajun country that will have readers of all ages hungry for more. Praise for The Cajun Cornbread Boy“An old tale sprouts legs and takes off, enlivened by a dash of Cajun flavor. Catch it if you can!” —Aaron Sheard, The Author of Lightning Larry“Dianne de Las Casas mixes humor, high spirits, lively narration and a colorful setting to bring alive the timeless tale of the Gingerbread Boy.” —Robert D. San Souci, author of The Talking Eggs: A Folktale from the American South and Little Pierre: A Cajun Story from LouisianaVer libro
