This new resource in the Requisites in Pediatrics series focuses on the assessment and treatment of pulmonary disorders commonly encountered in clinical practice. Abundant tables examine differential diagnosis, lab values/radiologic studies, treatment/therapy options, and when to refer to a specialist. A consistent organization throughout makes review easy, and chapters end with lists of key points. It's the ideal reference for a quick, efficient, and comprehensive review of essential information needed for board examinations or recertification.

Tap into the definitive source that continues to serve pediatric surgeons throughout the world. With more than 200 expert contributors and under the new editorial leadership of Dr. Jay Grosfeld, this 6th Edition features comprehensive, up-to-date information on all aspects of childhood surgery, emphasizing congenital malformations, tumors, trauma, and urologic problems.

Although, the basic concept of a fuel cell is quite simple, creating new designs and optimizing their performance takes serious work and a mastery of several technical areas. PEM Fuel Cell Modeling and Simulation Using Matlab, provides design engineers and researchers with a valuable tool for understanding and overcoming barriers to designing and building the next generation of PEM Fuel Cells. With this book, engineers can test components and verify designs in the development phase, saving both time and money.

Easy to read and understand, this book provides design and modelling tips for fuel cell components such as: modelling proton exchange structure, catalyst layers, gas diffusion, fuel distribution structures, fuel cell stacks and fuel cell plant. This book includes design advice and MATLAB and FEMLAB codes for Fuel Cell types such as: polymer electrolyte, direct methanol and solid oxide fuel cells. This book also includes types for one, two and three dimensional modeling and two-phase flow phenomena and microfluidics.

*Modeling and design validation techniques
*Covers most types of Fuel Cell including SOFC
*MATLAB and FEMLAB modelling codes
*Translates basic phenomena into mathematical equations

Fuel cells are electrochemical energy conversion devices that convert hydrogen and oxygen into water, producing electricity and heat in the process and providing fuel efficiency and reductions in pollutants. Demand for this technology is growing rapidly. Fuel cells are being commercialized for stationary and portable electricity generation, and as a replacement for internal combustion engines in automobiles. Proton Exchange Membrane (PEM) fuel cells in particular are experiencing an upsurge. They have high power density and can vary their output quickly to meet shifts in power demand.

Until now, there has been little written about this important technology. This book lays the groundwork for fuel cell engineers, technicians and students. It covers the fundamental aspects of fuel cell design, electrochemistry of the technology, heat and mass transport, system design and applications to bring this technology to professionals at all levels.

* Comprehensive guide for engineers, researchers and policymakers
* Covers theory and practice of PEM fuel cells
* Contains hundreds of original illustrations and real-life engineering examples
