Book excerpt: Forschungsarbeit aus dem Jahr 2004 im Fachbereich Medizin - Zahnmedizin, University of Mosul (Dental college), Sprache: Deutsch, Abstract: This study was carried out to evaluate the colour property of two types of acrylic resin materials cured by microwave technique in comparison with that cured by conventional water bath technique. Two types of heat cured acrylic resin materials were selected: Quayle–Dental and Major–base types. Seventy–two samples (30×20×1.5 mm) were prepared and divided into four experimental groups: Quayle–Dental and Major–base groups were cured by microwave technique and the others Quayle–Dental and Major–base groups were cured by water–bath technique. The number of samples for each group was 18. The colour property for the samples was evaluated using computerized ultra-violet–visible spectrophotometer with acc-uracy up to 0.001 nm. The absorbed light was measured which is also termed the optical density. The results of this study showed that there were no significant differences in optical density for acrylic resin samples cured by microwave and water–bath techniques, and the acrylic resin with smaller particle size (Quayle–Dental) showed higher optical density (colour property) than that of larger particle size (Major–base). Key Words: Optical density, colour prop-erty, microwave technique.

This book was released on 2013-01-31 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (postgraduate) from the year 2012 in the subject Medicine - Dentistry, University of Mosul (Department of Prosthetic Dentistry/ College of Dentistry), language: English, abstract: The total number of samples (45) were divided into three main groups cured according to three curing cycles (The standard short cycle, rapid was subdivided into three subgroup: The control group (without additives), samples prepared with the addition of Nigella Sativa , and samples prepared with the addition of Thyme oil. Color was measured for all the samples. Results were analyzed statistically by (Descriptive statistics, ANOVA and Duncan’s multiple range test) and showed that both additives(Nigella Sativa and Thyme oil) showed significant changes in the color of denture base. conclusion Both additives (Nigella sativa and Thyme oil) showed significant changes in the color of acrylic resin denture base material. The addition of Thyme oil to the samples cured by the regular heat curing cycle showed color change (ΔE=3.376) in relation to the standard (ADA) cycle which is an acceptable range in vitro. This study were to evaluate the effect of Nigella sativa and Thyme oil on The color of Acrylic Resin Denture Base Material.

Book excerpt: Recent advances in power electronics greatly benefit the multidisciplinary field of modern ultrasonics. More powerful, compact, and versatile electronic chips and software enable new computer-based devices for real-time data capture, storage, analysis, and display and advance the science and technology employed in commercial systems and applications of ultrasound. Reviewing the scientific basis behind these improvements, Ultrasonics: Fundamentals, Technologies, and Applications, Third Edition discusses them in detail, with new and additional figures and references, offering a completely revised and expanded examination of the state of modern ultrasonics. This new edition of a bestselling industry reference discusses the full breadth of ultrasonics applications for industrial and medical use and provides the fundamentals and insights gathered over the authors’ collective 80 years in the field. It provides a unique and comprehensive treatment of the science and technology behind the latest advancements and applications in both low and high power implementations. Coverage combines fundamental physics, a review and analysis of sensors and transducers, and the systems required for the full spectrum of industrial, nondestructive testing and medical and biomedical uses. It includes citations of numerous references and covers both main stream and the more unusual and obscure applications of ultrasound. Ultrasonics is ubiquitous in its industrial applications for sensing, NDT, and process measurements, in high power forms for processing and sonochemistry, as well as in medical procedures where it is used for diagnosis, therapy and surgery. This book provides a complete overview of the field, presenting numerous applications, cutting-edge advancements and improvements, additional figures and references, and a look at future directions.
