Galvanic gold plating for fixed dental prosthesis
Metal ceramic partial fixed dental prostheses have been commonly used for the replacement of missing teeth for many years. Because of an increase in the price of gold, base metal alloys have been the choice of alloy for the fabrication of metal ceramic restorations in many dental clinics. Some major disadvantages of base metals are their corrosion and the dark coloration they may cause at the c...
متن کاملEstimating the Effects of Gold Plating Using Fuzzy Cognitive Maps
The systems and software development industry is characterized by a paradigm of project failure. There are various factors that can lead to project failure .One such factor is gold plating. Gold plating can cause various problems in the projects like increase in project complexity, use of more resources, and increase in time and budget of the project and many more. If effects of gold plating ar...

متن کاملDesigning Hollow Nano Gold Golf Balls
Hollow/porous nanoparticles, including nanocarriers, nanoshells, and mesoporous materials have applications in catalysis, photonics, biosensing, and delivery of theranostic agents. Using a hierarchical template synthesis scheme, we have synthesized a nanocarrier mimicking a golf ball, consisting of (i) solid silica core with a pitted gold surface and (ii) a hollow/porous gold shell without sili...
متن کاملPanning for Gold: Designing Pedagogically-inspired Learning Nuggets
Tools to support teachers and learning technologists in the creation of effective learning designs are currently in their infancy. This paper describes a metadata model, devised to assist in the conception and design of new learning activities, that has been developed, used and evaluated over a period of three years. The online tool that embodies this model was not originally intended to produc...
