Research in the pharmaceutical industry today is in many respects quite different from what it used to be only fifteen years ago. There have been dramatic changes in approaches for identifying new chemical entities with a desired biological activity. While chemical modification of existing leads was the most important approach in the 1970s and 1980s, high-throughput screening and structure-based design are now major players among a multitude of methods used in drug discov ery. Quite often, companies favor one of these relatively new approaches over the other, e.g., screening over rational design, or vice versa, but we believe that an intelligent and concerted use of several or all methods currently available to drug discovery will be more successful in the medium term. What has changed most significantly in the past few years is the time available for identifying new chemical entities. Because of the high costs of drug discovery projects, pressure for maximum success in the shortest possible time is higher than ever. In addition, the multidisciplinary character of the field is much more pronounced today than it used to be. As a consequence, researchers and project managers in the pharmaceutical industry should have a solid knowledge of the more important methods available to drug discovery, because it is the rapidly and intelligently combined use of these which will determine the success or failure of preclinical projects.

Aero engine bearing chambers are complex machine elements inside the engines, supporting up to three concentric shafts on bearings. For safety reasons, the aero engines always employ rolling-element type bearings and therefore require a sufficient oil supply for lubrication in order to guarantee a reliable operation. As a consequence, a complex two-phase flow consisting of oil and sealing air governs the bearing chambers. A highly dynamic oil film, flowing along the chamber walls, plays a vital role to fulfill the tasks of cooling, lubricating and cleaning the bearing chambers. The design and optimization process of the bearing chambers requires a detailed understanding in order to accurately simulate the film behaviour inside the bearing chambers. Based on the earlier experimental investigations, it is known that near the scavenge off-take a relatively thick film exists. The numerical model to simulate these films must therefore take into account the elliptical behaviour of such films. Among the different models, the Volume Of Fluid (VOF) Model offers the best compromise between accuracy and efforts. However, preliminary attempts to model a fully developed and turbulent test case from literature revealed an unphysical pressure drop and velocity profile in the gas phase above the film flow. An inadequate turbulence modelling near the gas-liquid interface was identified as the problem source. The 2-Equation turbulence models (k- epsilon & k- omega) were extended to achieve a substantial improvement.

The one-stop resource for rubber-clay nanocomposite information The first comprehensive, single-volume book to compile all the most important data on rubber-clay nanocomposites in one place, Rubber-Clay Nanocomposites: Science, Technology, and Applications reviews rubber-clay nanocomposites in an easy-to-reference format designed for R&D professionals. Including contributions from experts from North America, Europe, and Asia, the book explores the properties of compounds with rubber-clay nanocomposites, including their rheology, curing kinetics, mechanical properties, and many others. Rubber-clay nanocomposites are of growing interest to the scientific and technological community, and have been shown to improve rubber compound reinforcement and impermeability. These natural mineral fillers are of potential interest for large-scale applications and are already making an impact in several major fields. Packed with valuable information about the synthesis, processing, and mechanics of these reinforced rubbers, the book covers assorted rubber-clay nanocomposites applications, such as in automotive tires and as polymer fillers. Promoting common knowledge and interpretation of the most important aspects of rubber-clay nanocomposites, and clarifying the main results achieved in the field of rubbers and crosslinked rubbers something not covered in other books in the field Rubber-Clay Nanocomposites helps scientists understand morphology, vulcanization, permeability, processing methods, and characterization factors quickly and easily.

Enzymatic catalysis has gained considerable attention in recent years as an efficient tool in the preparation of natural products, pharmaceuticals, fine chemicals, and food ingredients. The high selectivity and mild reaction con- tions associated with enzymatic transformations have made this approach an attractive alternative in the synthesis of complex bioactive compounds, which are often difficult to obtain by standard chemical routes. However, the maj- ity of organic compounds are not very soluble in water, which was traditi- ally perceived as the only suitable reaction medium for the application of biocatalysts. The realization that most enzymes can function perfectly well under nearly anhydrous conditions and, in addition, display a number of useful properties, e. g. , highly enhanced stability and different selectivity, has d- matically widened the scope of their application to the organic synthesis. Another great attraction of using organic solvents rather than water as a reaction solvent is the ability to perform synthetic transformations with re- tively inexpensive hydrolytic enzymes. It is worth reminding the reader that in vivo, the synthetic and hydrolytic pathways are catalyzed by different enzymes. However, elimination of water from the reaction mixture enables the "reversal" of hydrolytic enzymes and thus avoids the use of the expensive cofactors or activated substrates that are required for their synthetic count- parts.

The next article includes the description of the rich chemistry of phosphinines, including azaphosphinines. The sixth article deals with synthetic approaches to different types of 1- heterophosphacyclanes, including four-, five-, and six-membered P-heterocycles. The next two articles cover the chemistry of phosphorus containing mac- cycles. The phosphorus containing calixarenes have attracted much attention in recent years due to their various functions such as metal cations binding, catalysis, molecular recogination, and bioactivity. Likewise, other phosphorus-containing macrocycles, cryptands, and dendrimers find various uses in analytical chemistry and biochemistry. We hope to include the following articles in the second volume on phosphorous heterocycles: Diazaphospholes Selected phosphorous heterocycles containing a stereogenic phosphorus Heterophenes carrying phosphorus functional groups as key structures The synthesis and chemistry of the phospholane ring system Synthesis and bioactivity of 2,5-dihydro-1,2-oxaphosphole-2-oxide derivatives Recent developments in the chemistry of N-heterocyclic phosphines. I would be failing in my duty if I do not express my sincere thanks to the people at Springer, particularly Ms. Birgit Kollmar-Thoni and Ms. Ingrid Samide, for coordinating the project with great dedication.

The analysis and modification of glycans of recombinant proteins continues to be active and challenging area of research and for the successful manufacture of these proteins. In Cell Engineering, volume 3: Glycosylation, Dr. Mohammed Al-Rubeai has compiled a group of articles that will provide research workers not only with reviews of the advances that have been made in all facets of the subject but with an in-depth assessment of the state of the art methodology and the various approaches for the improvement of glycoprotein production. Particularly important in this respect is the advances made in the development of genetically engineered host cell lines with novel glycosylation properties, as well as the integration of mass spectrophotometric analysis with separation techniques.

This volume is intended not only for research students and senior scientists in cell culture and glycobiology, but also for industrial biotechnologists and biochemical engineers interested in the production of therapeutic glycoproteins, virus vector and ex vivo expansion of human cells for medical treatment.

More then 20 years have passed now since the first recombinant protein producing microorganisms have been developed. In the meanwhile, numerous proteins have been produced in bacteria, yeasts and filamentous fungi, as weIl as higher eukaryotic cells, and even entire plants and animals. Many recombinant proteins are on the market today, and some of them reached substantial market volumes. On the first sight one would expect the technology - including the physiology of the host strains - to be optimised in detail after a 20 year's period of development. However, several constraints have limited the incentive for optimisation, especially in the pharmaceutical industry like the urge to proceed quickly or the requirement to define the production parameters for registration early in the development phase. The additional expenses for registration of a new production strain often prohibits a change to an optimised strain. A continuous optimisation of the entire production process is not feasible for the same reasons.

This book provides the background needed to understand not only the wide field of polymer processing, but also the emerging technologies associated with the plastics industry in the 21st Century.

From reviews of the hardback:

Itraconazole nanoparticles with suitable size ranges are expected to improve the therapeutic efficacy and reduction of toxicity of this broad spectrum antifungal agent. Components of the SLNs were lipid (palmitic acid) and surfactants (Pluronic F127 and Tween 40). The Itraconazole loaded nanoparticles were prepared by microemulsion dispersion method. Particles size analysis and zeta potential measurements were done using Malvern Mastersizer Hydro 2000G. The particles were also subjected to DSC, IR and XRD analyses.The study elaborates on the feasibility and suitability of lipid based colloidal drug delivery system, employing optimize design to develop a clinically useful nanoparticle system with targeting potential. It is expected that this type of itraconazole loaded lipid nanoparticulate system could be clinically effective in better management of systemic and ocular inflammation with greater degree of safety and efficacy. Therefore, no doubt that the book will be of great use for the researchers those who are working on nano drug delivery system for BCS class drugs in India and abroad as well.
