High temperature PEMFCs (HT PEMFCs), operating at 120 C - 200 C are rather new and offer tremendous advantages. For instance fuel cells operating at > 100 C reduce issues related to water management substantially. Circulating excess heat energy from such fuel cells into other system processes where heat is needed would be much more practical (due to higher DeltaT) compared to the standard LT PEMFCs where the produced heat has less than 90 C (lower DeltaT). Higher tolerance to fuel impurities such as CO, by these HT PEMFCs has made them very practical for many applications. Although PBI/H3PO4 based membranes have been explored for use in PEMFCs from the early 1990s, only recently PEMEAS (curr...
A three-dimensional computational fluid dynamics model of a high temperature polymer electrolyte membrane fuel cell, employing a high temperature stable polybenzimidazole membrane electrode assembly doped with phosphoric acid, was developed and implemented using a commercially available finite element software. Three types of flow-fields were modeled and simulated. Selected simulation results at reference operating conditions were compared to the performance curves and to segmented solid-phase temperature and current density measurements. For the segmented measurements, an inhouse developed prototype cell was designed and manufactured. The segmented cell was successfully operated and the sol...

Focusing on race, culture, acculturation, ethnicity, and ethnic identity—concepts commonly used to account for the behaviors of Asian Americans and other minorities—A Postmodern Psychology of Asian Americans examines the effects of modern psychology's epistemological and ontological premises on its investigative methods and concepts. Author Laura Uba looks at the social creation of psychological facts, including portrayals of ethnic and racial groups, and demonstrates, especially in ways pertinent to the study of minorities, that modern psychology needs to reconsider its ways of thinking about study samples, investigative methods, facts, and concepts used to describe and explain behaviors.
Difference, Dialogue, and Development is an in-depth exploration of the collected works of Mikhail Bakhtin to find relevance of key concepts of dialogism for understanding various aspects of human development. Taking the reality of differences in the world as a given, Bandlamudi argues that such a reality necessitates dialogue, and actively responding to that necessity leads to development. The varied works of Bakhtin that span several decades passing through the most tumultuous period in Russian history, are brought under one banner of three D’s – Difference, Dialogue and Development – and the composite features of the three D’s emerge as leitmotifs in every chapter.
Indigenous people (tribals) are viewed as historical objects of curiosity worldwide. In India, tribes have been marginalised by the creation of administrative boundaries and further hedged in by administrative (forest and land) policies, legislations, colonial and modern market economic orientations, technology, indifferent state policies and social pressures. The way of life of tribal communities, and production and distribution relations among them, has undergone significant changes in recent decades. It is necessary to enquire as to how these changes were brought about and to consider their impact in a historical context. This book brings together issues like the variations in the magnitu...
This case-based atlas encompasses all aspects of imaging in congenital cardiac defects, cardiac masses, inflammatory and acquired heart diseases, cardiomyopathies and coronary-related pathologies. The chapters begin with a description of the imaging approach, followed by cases comprehensively covering the gamut of clinical scenarios that may be encountered in clinical practice. The atlas provides pertinent information about each discussed disease state, its imaging diagnosis and recent advances, including role of radiology in management, follow up and prognostication. Cases that may pose as imaging differentials accompany the index case, followed by a variety of companion cases illustrating the possible spectrum of abnormalities that the reader may be confronted with while dealing with the index case. It acts as a guide for the cardiovascular radiologist, physician, paediatrician, internist, cardiologist, cardiothoracic surgeon as well as radiology residents for inculcating an evidence-based approach for choosing the right imaging algorithm in the given clinical situation. The highly visual design of the atlas enables it to act as a quick and ready reference.
'Dialogics of Self, the Mahabharata and Culture: The History of Understanding and Understanding of History' explores the interrelationships between individual and cultural historical dynamics in interpreting texts, using key concepts from Bakhtin's theory of dialogics. This ambitious volume discusses the limits of fixed monologic discourses and the benefits of fluid dialogic discourses, and provides a cultural and psychological analysis of the epic Indian text the 'Mahabharata'. The problem addressed by 'Dialogics of Self, the Mahabharata and Culture' is not just how we understand and narrate history, but also how the very mechanism by which we understand and narrate history itself has a history. This volume is about the interplay of several histories - that of the individual, individual's past relationship to the text, which in turn is dependent on the nature of encounters they have had in the past, and the history of the text, and the very history of understanding.
