This book describes the state-of-the-art advancement in the field of organic electroluminescence contributed by many researchers with internationally established expertise in the field. It includes original contributions on the synthesis of suitable organic materials, fabrication of organic light emitting devices (OLEDs) and organic white light emitting devices (WOLEDs), characterization of these devices and some designs for optimal performance. All chapters are self-sufficient in presenting their contents. The cost effective chemical technology offers many exciting possibilities for OLEDs and organic solar cells (OSCs) to be futuristic solutions for lighting and power generation. A common flexible substrate can be used to fabricate OLEDs on one side facing a room and OSCs on the other side facing the sun. The device thus fabricated can generate power in the day time and light a room/house at night. The book covers developments on OLEDs, WOLEDs and briefly on OSCs as well.

The highly specialized nature of marine mammals when compared with their terrestrial counterparts, the environment in which they live, and the impact of humans on them throughout history and at the present, have made of the scholarship on these creatures something unique in itself. Therefore, it is not surprising that many researchers have also taken a distinctive approach to their study.This volume is aimed at providing a glimpse at such diversity of views and approaches while delivering valuable information on marine mammalogy. Given the increasing concerns regarding issues of anthropogenic factors affecting these animals, it is not surprising that the majority of chapters in this book deal with this subject.

Telomeres, located at the ends of linear chromosomes, are essential for genome stability and integrity. Advances in telomere researches have linked telomere dysfunction with cellular aging and a number of age-related human diseases.

Bearings (both plain and rolling element) are used as important supporting elements for locating rotating components and confining their motion in desired direction. In order to ensure their operational reliability and desired life, these need to be properly designed/selected for an application more so because of ever increasing operational speeds. This requires the careful performance evaluation of different types of bearings considering aspects such as thermal stability, lubrication, contaminants in lubricants and controlling mechanism etc. The title of this book was specifically chosen as Performance Evaluation of Bearings. The present book is a compilation of different aspects contributing towards the performance evaluation of plain bearings (both journal and thrust), rolling element bearings and magnetic bearings.

Free radicals are constantly formed in living cells and removed by antioxidant defenses. Antioxidant enzymes are the main line of defense against free radicals in animal and plant cells. Uncontrolled generation ROS are involved in a number of human disease states, including diabetes and cancer due to disturbance in cellular and molecular processes including cell growth, differentiation and proliferation. When cells are exposed to oxidative stress a defense system endorses the expression and regulation of number of antioxidant enzymes as a defense mechanism to protect them from the damage induced by free radicals. Based on this fact, the book "Antioxidant Enzymes" was designed to overview the importance of the antioxidant enzymes in human and plant cells against toxic free radicals, their relationship with several pathophysiologic processes and their possible therapeutic application.

It presents up to date results on communication systems, along with the explanations of their relevance, from leading researchers in this field. The chapters cover general concepts of optical communication, components, systems, networks, signal processing and MIMO systems. In recent years, optical components and other enhanced signal processing functions are also considered in depth for optical communications systems. The researcher has also concentrated on optical devices, networking, signal processing, and MIMO systems and other enhanced functions for optical communication. This book is targeted at research, development and design engineers from the teams in manufacturing industry, academia and telecommunication industries.

Addiction, increasingly perceived as a heterogeneous brain disorder, is one of the most peculiar psychiatric pathologies in that its management involves various, often non-overlapping, resources from the biological, psychological, medical, economical, social, and legal realms. Despite extensive efforts from the players of these various fields, to date there are no reliably effective treatments of addiction. This may stem from a lack of understanding of the etiology and pathophysiology of this disorder as well as from the lack of interest into the potential differences among patients in the way they interact compulsively with their drug. This book offers an overview of the psychobiology of addiction and its current management strategies from pharmacological, social, behavioural, and psychiatric points of view.

In this book we provide an update on several aspects of sepsis. Starting from the history of the disease and finishing with treatment of sepsis-associated organ dysfunctions, this book offers a wide scope of well-written and complete reviews concerning pathophysiological and therapeutic characteristics of sepsis. We hope that the work of the authors will provide a significant forum of discussion on the topic, and increase the awareness of the healthcare team regarding the important aspects of early recognition and treatment of this severe condition.

During the last two decades, evidence of increasing trends of several endocrine-related disorders has been strengthened. These disorders often come with lack of uniform diagnosis and/ or even unclear endocrine disruption. The later is mainly due to abnormal classical changes in the blood- released hormone to its targeted organ, abnormal communication between cells within a tissue or organ (paracrine), within the same cell (intracrine) or signals which act on the same cell (autocrine). This challenging status drives endocrinologists to the urgent need to address enormous knowledge gaps in this wide field of research (Endocrinology). From the perspective point of view that "hormones control our bodies", we need to get these hormones rebalanced so we can restore overall health. That is simply endocrinology!
