  • In recent years, the remarkable advances in medical imaging instruments have increased their use considerably for diagnostics as well as planning and follow-up of treatment. Emerging from the fields of radiology, medical physics and engineering, medical imaging no longer simply deals with the technology and interpretation of radiographic images. The limitless possibilities presented by computer science and technology, coupled with engineering advances in signal processing, optics and nuclear medicine have created the vastly expanded field of medical imaging.

  • In the last two decades, many books have been published on ion implantation and ion-beam processing. Why this one now? After all, the advantages of using an energetic ion beam to modify surfaces with a view to enhancing their tribological, electrochemical, optical and magnetic properties have been known for some time. The aim of this volume is to review the basics of previous work on ion-beam modification of materials and to include enough new material on novel applications to bring newcomers “up to speed” in this exciting area....

  • Written by two of the foremost researchers in the field, this book studies the local times of Markov processes by employing isomorphism theorems that relate them to certain associated Gaussian processes. It builds to this material through self-contained but harmonized “mini-courses” on the relevant ingredients, which assume only knowledge of measuretheoretic probability. The streamlined selection of topics creates an easy entrance for students and experts in related fields.

  • Electrodeposition kinetics of Co thin film were investigated and magnetic coercivity of the deposited films were studied using potentiostatic technique and magnetic hyteresis loop measurements. Results showed that the nucleation mechanism of the electrodeposition process changed from instantaneous mode to progressive mode when potential was changed from –0.7 V to –0.8 V. The magnetic coercivity Hc increases with deposition time and the film with Hc < 15 Oe can be obtained with deposition time t < 5 s.

  • Over time, the costs of processing go down because as organization learn how to di things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print fell from 50cents for five-day service in 1970 to 20 cents for one-day service in 1984.

  • The chapter commences by reviewing the properties of the broad classes of materials used in film coating, polymers, plasticizers, pigments and solvents (or vehicles). An initial consideration of the polymers shows that while processing is most commonly performed using these materials in solution, there are systems which utilize polymers in suspension in water. The mechanism of coalescence and film formation for these types of materials are discussed.

  • Solution properties and atomization in film coating Michael E.Aulton and Andrew M.Twitchell SUMMARY A little-considered stage of the film-coating process is the atomization of the coating solution by the spray gun. This chapter will show how formulation and process factors can cause marked changes in the characteristics of the spray, which may have important consequences for film formation and film properties.

  • The coating process Graham C.Cole SUMMARY In recent years tablet coating has undergone several fundamental changes. The original sugar-coating technique has been largely replaced by film-coating processes using organic solvents. The organic solvents are now being replaced by water because of the development of suitable polymers, improvements in the coating process, and legislation regulating the discharge of pollutants into the environment.

  • Surface effects in film coating Michael E.Aulton SUMMARY This chapter will explain the significance of the stages of impingement, wetting, spreading and penetration of atomized droplets at the surface of tablet or multiparticulate cores. It will explain some of the fundamental aspects of solid-liquid interfaces which are important to the process of film coating. This chapter will emphasize the importance of controlling the ‘wetting power’ of the spray and the ‘wettability’ of the substrate, and will explain how this can be achieved by changes in formulation and process parameters.

  • Environmental considerations: treatment of exhaust gases from film-coating processes Graham C.Cole SUMMARY Solvents such as acetone, methylene chloride, chloroform, ethanol and methanol must be prevented from entering the environment. Two options are available: convert all the processes to aqueous-based formulations or recover all the solvent by the use of an appropriate system. Recovery is expensive and is generally the reason for pharmaceutical companies to convert coating formulations to aqueous systems or formulate aqueous coating for all new products.

  • According to American Society for Testing and Materials' corrosion glossary, corrosion is defined as "the chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties".1 Other definitions include Fontana's description that corrosion is the extractive metallurgy in reverse,2 which is expected since metals thermodynamically are less stable in their elemental forms than in their compound forms as ores.

  • The development of film-coating processes Graham C.Cole SUMMARY To develop a film-coating process requires a laboratory test rig that can be scaled-up to meet production requirements. All the process parameters need to be optimized. A scheme is discussed here that provides an integrated computer-controlled system designed for aqueous film coating in a side-vented pan. A comparison is made of energy requirements of a column-coating system and a coating pan. All the major operational coating parameters can be measured and recorded under the overall control of a microcomputer.

  • Image registration is an emerging topic in image processing with many applications in medical imaging, picture and movie processing. The classical problem of image registration is concerned with finding an appropriate transformation between two data sets. This fuzzy definition of registration requires a mathematical modeling and in particular a mathematical specification of the terms appropriate transformations and correlation between data sets. Depending on the type of application, typically Euler, rigid, plastic, elastic deformations are considered.

  • The definition for dielectric constant relates to the permittivity of the material (symbol use here ε). The permittivity expresses the ability of a material to polarise in response to an applied field. It is the ratio of the permittivity of the dielectric to the permittivity of a vacuum. Physically it means the greater the polarisation developed by a material in an applied field of given strength, the greater the dielectric constant will be. Traditionally dielectric materials are made from inorganic substances eg. mica and silicon dioxide.

  • Catalysis and Electrocatalysis at Nanoparticle Surfaces reflects many of the new developments of catalysis, surface science, and electrochemistry. The first three chapters indicate the sophistication of the theory in simulating catalytic processes that occur at the solid–liquid and solid–gas interface in the presence of external potential. The first chapter, by Koper and colleagues, discusses the theory of modeling of catalytic and electrocatalytic reactions.
