Pulsatile Drug Delivery Systems are gaining a lot of interest as these systems deliver the drug at specific time as per the pathophysiological need of the disease, thus providing spatial and temporal delivery and increasing patient compliance. Diseases wherein such delivery systems are promising include asthma, peptic ulcer, cardiovascular diseases, arthritis, attention deficit syndrome in children, and hypercholesterolemia. This book will cover various approaches that have been developed to control drug delivery profile with different polymeric systems like time controlling, internal stimuli induced (temperature induced and chemical stimuli-induced),external induced (magnetic fields, ultrasound, electric fields and light stimulation) and Multiparticulate system. Special attention have been made towards recent advances, patents, future opportunity and major challenges regarding formulation of pulsatile drug delivery of oral dosage forms and are summarized and discussed.

This book gives readers an in-depth analysis of the fundamentals behind designing on-demand medium access control (MAC) protocols for multihop wireless networks, esp. with nodes having multiple antenna technologies. This is the first attempt towards designing and analyzing on-demand, also known as contention-based, MAC protocols for multiple beam smart antennas (MBSA). The book begins with a general introduction of the state-of-art problems and solutions that then forms the basis of this book. The book then introduces mathematical models to analyze MBSA and derive basic MAC fundamentals. The readers are then exposed to step-by-step MAC design for MBSA in wireless ad hoc networks. Once the basic design is completed, advanced concepts such as wireless mesh network architecture, Quality of Service (QoS), interoperability with existing IEEE802.11 standards and co-existence with other antenna technologies, viz., omnidirectional and directional, are introduced. Finally, the book ends with introducing link layer reliable and energy-efficient communication mechanisms for wireless sensor networks.

Fully revised, this second edition presents trainees with the latest guidance on preparation for OSCE examinations. Comprised of fourteen chapters, the book covers all the key learning points and provides an understanding of the basic concepts behind the OSCE and advice on appropriate response.
