Soliton Management in Periodic Systems
This book provides a unique and informative account of the state-of-the-art in the field. The volume opens with a review of the existence of robust solitary pulses in systems built as a periodic concatenation of very different elements. Among the most famous examples of this type of systems are the dispersion management in fiber-optic telecommunication links, and (more recently) photonic crystals. A number of other systems belonging to the same broad class of spatially periodic strongly inhomogeneous media (such as the split-step and tandem models) have recently been identified in nonlinear optics, and transmission of solitary pulses in them was investigated in detail.

Solid self micro emulsifying drug delivery system
Explores the formulation of Solid Self-Microemulsifying Drug Delivery Systems (SSMEDDS) as a strategy to enhance oral bioavailability and reduce GI side effects of NSAIDs. Tiaprofenic acid, a poorly soluble acidic NSAID, was selected as a model drug to develop and evaluate the delivery system. Excipients were selected using Hansen solubility parameters. While castor oil showed optimal solubility, it was excluded due to known irritancy. Olive oil was chosen for its adequate solubilization capacity and documented gastric protective effects. The optimized SMEDDS formulation was solidified via adsorption on Aerosil.
Solar-Type Activity in Main-Sequence Stars
In this monograph observational results are summarized in a systematic and comprehensive fashion. The analysis of the various manifestations of such stellar activity leads to the identification of these phenomena with macroscopic non-linear processes in a magnetized plasma. Comparative study of flare stars and the Sun has become increasingly fruitful and is presently an active field of research involving stellar and solar physicists, experts in plasma physics and high-energy astrophysicists. This book will provide them with both an introduction and overview of observational results from the first optical photometry and spectroscopy, from the satellite telescopes International Ultraviolet Explorer to Hubble Space Telescope, XMM-Newton and Chandra, as well as with the present physical interpretation of solar-type activity in main sequence stars. Gershberg's 40-year career studying UV Cet type stars and related objects enables him to provide readers with expert insight into the characteristics of such stars in both the quiescent state and during flares and the reliability of the data over the electromagnetic spectrum and wide temporal scales.
