PURPOSE The aim of this study was to compare the color stability, water sorption and cytotoxicity of thermoplastic acrylic resin for the non-metal clasp dentures to those of thermoplastic polyamide and conventional heat-polymerized denture base resins. MATERIALS AND METHODS Three types of denture base resin, which are conventional heat-polymerized acrylic resin (Paladent 20), thermoplastic po...
We present a color liquid-crystal-on-silicon microdisplay that integrates color filters on silicon for colors. Fabrication parameters, color purity and light stability of this breed of microdisplays were characterized. A single-panel WXGA color projector based on this color filter microdisplay technology was demonstrated.
In order to evaluate of distinctness, uniformity and stability (DUS) of morphological traits, three new genotypes of cotton (GT40, TBL60 and SKT134) were tested using a complete randomized blocks design with 4 replications. In general, 39 quantitative and qualitative morphological characteristics were measured. Results showed quantitative morphological characteristics including number of stem n...
UNLABELLED Soft linings are materials used to reduce the tension and forces of mastication, forming all or part of the fitting surface of a denture. This study evaluated the effect of thermocycling on water absorption, solubility, Shore A hardness and color stability of permanent soft liner materials. MATERIAL AND METHODS Two chemically activated soft liner materials (Sofreliner S; GC Reline ...
The color stability of a series of eleven maxillofacial pigments was determined after accelerated aging using reflection spectrophotometry. The results indicate that seven of the pigments demonstrated good to excellent color stability, while four of the pigments were less promising for clinical use.
The color stability of polyvinyl chloride, polyurethane, and silicone polymers for maxillofacial applications was determined after accelerated aging using reflectance spectrophotometry. On the basis of color stability after accelerated aging, and ease of processing, several silicone materials were the most promising.
Color of sun-dried tomato is an important quality criteria and color stability of sun dried tomatoes is affected by storage conditions such as temperature, time and packaging type. The objective of this study was to investigate the effects storage time, storage temperature and packaging type on color stability of sun-dried tomatoes by using factorial experimental design. In this study, the 2 3 ...
C4 composition is a conventional military explosive formulation based on cyclotrimethylenetrinitramine explosive (RDX) and polyisobutylene binder (PIB), which some environmental factors such as thermal and oxygen lead to change in its color and physical characteristics. Using anti-oxidant to reduce the impact of environmental factors and increasing the stability of materials...
The purpose of this study was to quantitatively evaluate the effect of staining solutions by spectrophotometric method on color stability of the commercially available acrylic denture base resins polymerized by different methods of cure, materials, and immersion periods. Commercially available heat cure resin (Travelon) and self cure resin (RR repair material) were selected for the study. In ca...
Contributions of initial and retained levels of oxygen consumption and reducing capacity to animal variation in color stability were evaluated. Instrumental color values were determined on longissimus steaks (n=257) during 6 d of display. Oxygen consumption (OC), nitric oxide metmyoglobin reduction (NORA), initial metmyoglobin formation (IMF), and post-reduction metmyoglobin (PRM) were measured...
