 Hui Li, Shanna Knights, Zheng Shi, John W. Van Zee, Jiujun Zhang, "Proton Exchange Membrane Fuel Cells: Contamination and Mitigation Strategies" English | 2019 | ISBN: 0367384272, 1439806780 | 436 pages | PDF | 8.65 MB Large-scale commercialization of proton exchange membrane fuel cell (PEMFC) technology has been hindered by issues of reliability, durability, and cost, which are all related to the degradation of fuel cell performance. This degradation often has root causes in contamination from fuel, air streams, or system components. With contributions from international scientists and engineers active in PEMFC research, Proton Exchange Membrane Fuel Cells: Contamination and Mitigation Strategies discusses the impacts of contamination and the contamination mitigation strategies to improve fuel cell performance and durability.

 Avinash Kak, "Programming with Objects: A Comparative Presentation of Object Oriented Programming with C++ and Java" English | 2003 | ISBN: 0471268526 | 1144 pages | PDF | 82.5 MB Your essential comparative approach to learning C++ and Java  Power Couples in Antiquity: Transversal Perspectives by Anne Bielman Sánchez English | Apr 2, 2019 | ISBN: 1138575267 | 226 pages | PDF | 4 MB Everyone can name a couple made up of famous, rich, or powerful partners, who cultivate a joint media image which is stronger than either of their individual identities. Since the 1980s they have been known as "power couples". Yet while the term is recent, the concept is not. More than 2,000 years ago, Greeks and Romans became aware of the media potential of couples and used it as an instrument to reinforce political power. Notable examples are Philip II of Macedonia and Olympias, Cleopatra and Mark Antony, or the Emperor Augustus and his wife Livia.  Portrait Painting - Drawing To Painting by Casper Zen Pedersen English | September 28, 2019 | ISBN: 169594819X | 114 pages | PDF | 2.75 Mb This book is meant to be for the very beginner who needs the basics and the most important information about portrait painting to start on his or her own. It's written chronologically so the reader knows what to start with and which skills needs to be achieved first in order to move forward with the personal development. What inspired me to write this book was the fact that I personally wasn't able to find any literature about making portraits from A-Z when I started painting. I wanted the most essential information to get me started. I bought tons of books and I was lucky to befriend one of Denmark's most famous and skilled portrait painters. With a combination of the above and many hours of practice, it took me around 6 years to be where I am now, ready to write a book that breaks it all down to the most essential part of portrait painting. Personally it was a very steep learning curve for me due to the fact that, going through all my material, I needed to separate the most relevant pieces of information from non-essential. Nevertheless, I persevered, and today I'm proud to be able to call myself a self-taught portrait painter. I want to share my self obtained knowledge to my fellow artists out there, those who do not have time to do research, or an academy to teach them. I want you to know that it is indeed possible to obtain a satisfying level without formal training if your heart is into it.  Polynomial Identities And Combinatorial Methods By Antonio Giambruno, Amitai Regev, Mikhail Zaicev 2003 | 427 Pages | ISBN: 0824740513 | PDF | 20 MB Presenting a wide range of perspectives on topics ranging from ring theory and combinatorics to invariant theory and associative algebras, this reference covers current breakthroughs and strategies impacting research on polynomial identities-identifying new concepts in algebraic combinatorics, invariant and representation theory, and Lie algebras and superalgebras for novel studies in the field.
 Michael Eikerling, Andrei Kulikovsky, "Polymer Electrolyte Fuel Cells: Physical Principles of Materials and Operation" English | 2014 | ISBN: 1138077445 | 582 pages | PDF | 18.2 MB The book provides a systematic and profound account of scientific challenges in fuel cell research. The introductory chapters bring readers up to date on the urgency and implications of the global energy challenge, the prospects of electrochemical energy conversion technologies, and the thermodynamic and electrochemical principles underlying the operation of polymer electrolyte fuel cells. The book then presents the scientific challenges in fuel cell research as a systematic account of distinct components, length scales, physicochemical processes, and scientific disciplines.  Political Concepts By Richard Bellamy, Andrew Mason 2003 | 254 Pages | ISBN: 0719059089 | PDF | 2 MB Eschewing the spirit of disillusionment often encountered in contemporary political theory, Bellamy (Univ. of Essex) and Andrew Mason (Univ. of Southhampton) have edited an anthology that presents "a broad range of the main concepts employed in contemporary debates among both political theorists and ordinary citizens." This laudable book consists of seventeen chapters on "political concepts" such as liberty, rights, and social justice, as well as legitimacy and welfare, and includes at least five chapters related to present-day controversies such as multiculturalism and green political theory. All essays are well-researched, accessible to a wide readership, and generally devoid of an overly technical vocabulary. The brevity of the chapters is an attribute of the volume that deserves special note. The chapters on liberty, legitimacy, and the rule of law also merit praise. Other chapters lack the philosophical rigor and precision of argument found in the rest of the book, as evinced in the chapter on gender. In returning to the importance of defining political concepts to encourage political understanding and ultimately participation, the volume makes a fine contribution.  Pocahontas: A Life from Beginning to End (Native American History) by Hourly History English | September 7, 2020 | ISBN: N/A | ASIN: B08HG8YHN1 | 45 pages | Rar (PDF, AZW3) | 0.63 Mb Discover the remarkable life of Pocahontas...The name Pocahontas is one of the most recognized in the world, and many think they know the story of how she met and fell in love with a European colonist meddling in her Native American affairs. But is this really what happened? It certainly has been a popular theme and whole Disney movies have been made celebrating this narrative, but besides these conveniently glossed-over tales, what is the real story?
