Pericyclic Reactions: A Mechanistic and Problem-Solving Approach provides complete and systematic coverage of pericyclic reactions for researchers and graduate students in organic chemistry and pharmacy programs. Drawing from their cumulative years of teaching in the area, the authors use a clear, problem-solving approach, supplemented with colorful figures and illustrative examples. Written in an accessible and engaging manner, this book covers electrocyclic reactions, sigmatropic reactions, cycloaddition reactions, 1,3-dipolar reactions, group transfer, and ene reactions. It offers an in-depth study of the basic principles of these topics, and devotes equal time to problems and their solutions to further explore those principles and aid reader understanding. Additional practice problems are provided for further study and course use.

Phytochemistry of Plants of Genus Phyllanthus (Phytochemical Investigations of Medicinal Plants)

Several Phyllanthus species are widely used in traditional medicine and herbal formulation for the treatment of a variety of ailments such as flu, dropsy, diabetes, jaundice and bladder calculus. The medicinal properties of these species are due to the presence of lignans, flavonoids, tannins, alkaloids and terpenoids. Phyllanthin and hypophyllanthin are the major lignans from Phyllanthus species having estrogenic properties that reduce toxicity and vascular tension, and protect hepatocytes. This book deals with the importance of separation techniques in screening of major lignans, flavonoids and terpenoids in Phyllanthus species using HPLC/UPLC coupled with mass spectrometric techniques. Features: <ul> <li>Collection of Ayurvedic features and scientific evidence of important medicinal plants.</li> <li>Screening of major lignans, flavonoids and terpenoids in plant parts/whole plant extracts and their geographical variations in Phyllanthus amarus.</li> <li>Easy-to-use analytical procedure for the quality control of Phyllanthus and its products.</li> </ul>

Rauvolfia species, commonly known as Sarpagandha has been traditionally used in Ayurveda for curing high blood pressure, hypertension, snake bites, feverish illnesses and insanity. Due to its wide variety and differences in chemical composition it is necessary to develop an efficient and reliable method, for rapid screening and determination of phytochemicals in extracts of Rauwolfia species. This book will provide qualitative and quantitative comparative phytochemical investigations of selected medicinal plants from Rauwolfia genus using LC-MS techniques. The results will help in assuring the efficacy and safety of Rauvolfia herbal products. Features: <ul> <li>Presents collection of Ayurvedic features and scientific evidence of an important medicinal plant.</li> <li>Discusses chemical signatures for identification of Sarpagandha and its products.</li> <li>Easy to use analytical procedure for quality control of Rauvolfia and its products.</li> </ul>

Multimedia over Cognitive Radio Networks: Algorithms, Protocols, and Experiments

With nearly 7 billion mobile phone subscriptions worldwide, mobility and computing have become pervasive in our society and business. Moreover, new mobile multimedia communication services are challenging telecommunication operators. To support the significant increase in multimedia traffic―especially video―over wireless networks, new technological infrastructure must be created. Cognitive Radio Networks (CRNs) are widely regarded as one of the most promising technologies for future wireless communications. This book explains how to efficiently deliver video, audio, and other data over CRNs. Covering advanced algorithms, protocols, and hardware-/software-based experiments, this book describes how to encode video in a prioritized way to send to dynamic radio links. It discusses different FEC codes for video reliability and explains how different machine learning algorithms can be used for video quality control. It also explains how to use readily available software tools to build a CRN simulation model.  This book explains both theoretical and experimental designs. It describes how universal software radio peripheral (USRP) boards can be used for real-time, high-resolution video transmission. It also discusses how a USRP board can sense the spectrum dynamics and how it can be controlled by GNU Radio software. A separate chapter discusses how the network simulator ns-2 can be used to build a simulated CRN platform.

Radio Resource Management for Multimedia QoS Support in Wireless Networks

Due to the great success and enormous impact of IP networks, In ternet access (such as sending and receiving e-mails) and web brows ing have become the ruling paradigm for next generation wireless systems. On the other hand, great technological and commercial success of services and applications is being witnessed in mobile wire less communications with examples of cellular, pes voice telephony and wireless LANs. The service paradigm has thus shifted from the conventional voice service to seamlessly integrated high quality mul timedia transmission over broadband wireless mobile networks. The multimedia content may include data, voice, audio, image, video and so on. With availability of more powerful portable devices, such as PDA, portable computer and cellular phone, coupled with the easier access to the core network (using a mobile device), the number of mobile users and the demand for multimedia-based applications is increasing rapidly. As a result, there is an urgent need for a sys tem that supports heterogeneous multimedia services and provides seamless access to the desired resources via wireless connections. Therefore, the convergence of multimedia communication and wireless mobile networking technologies into the next generation wireless multimedia (WMM) networks with the vision of "anytime, anywhere, anyform" information system is the certain trend in the foreseeable future. However, successful combination of these two technologies presents many challenges such as available spectral bandwidth, energy efficiency, seamless end-to-end communication, robustness, security, etc.
