Physical properties of resin-modified glass-ionomers.
The physical properties and shear bond strength of two resin-modified glass-ionomers: RMGIs (FJL and VT) and as a control, a conventional glass-ionomer: CGI (FJ), were evaluated. Ninety percent of the setting shrinkage under dry conditions and nominal hygroscopic expansion in water during 360 h occurred within the first 24 h. The nominal hygroscopic expansion of CGI was 0.38% while the RMGIs de...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولEffect of variations from the recommended powder/liquid ratio on some properties of resin-modified cements.
OBJECTIVES The powder and liquid contents of cements are mixed in accordance with the recommended mixing ratio, but discrepancies occur despite the use of proportioning scoops. Little is known about powder/liquid ratio variations on certain properties of resin-modified cements. METHODS Two resin-modified glass ionomer cements (RMGIC) were mixed using various powder/liquid ratios: (a) Recommen...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
comparison of mechanical properties of resin composites with resin modified glass ionomers
statement of problem: there are controversial reports regarding physical and mechanical properties of resin composites and glass ionomer cements. some revealed higher strength and hardness for resin composites while others showed a comparable value for glass ionomer cements. evaluation of mechanical properties of different types of resin composites in comparison with resin modified glass ionome...
