In this study, we investigated the effect of different solutions--coffee, tea, Turkish coffee, artificial saliva, mouthwash, denture cleanser, and distilled water--on the bond strength of soft lining materials (one acrylic- and three silicone-based) to acrylic resin. Acrylic specimens (40x10x10 mm) were prepared for the bond strength test. The specimens were stored in different solutions and te...

An exothermic reaction, leading to 3-(2-furyl)acrylic anhydride and a little amount of furfurylideneacetone is taking place when reacting 3-(2-furyl)acrylic acid in acetic anhydride above 120°C. The 3-(5-acetyl-2-furyl)acrylic acid was formed under the afore-mentioned conditions only in the presence of H 3 P 0 4 . The 3-(2-furyl)acrylic anhydride is more stable towards HNO, at temperatures unde...

This study investigated the hygroscopicity and UV deterioration characteristics of 3 domestic 4 imported woods using natural oil, stain, varnish paints. In terms hygroscopicity, it was found that painted wood lower than unpainted wood, as number coatings increased, decreased. anti-absorption, oil-based chemical paints showed higher resistance water-based paints, oils results comparable to As fo...

A novel microorganism, designated as LG12, was isolated from soil based on its ability to use acrylic acid as the sole carbon source. An electron microscopic analysis of its morphological characteristics and phylogenetic classification by 16S rRNA homology showed that the LG12 strain belongs to Rhodococcus erythropolis. R. erythropolis LG12 was able to metabolize a high concentration of acrylic...

BACKGROUND Acrylic teeth have long been used in the treatment of a complete denture. One of the primary advantages of acrylic teeth is their ability to adhesively bond to the denture base resins. Although the bonding seems satisfactory, however, bond failures at the acrylic teeth and denture base resin interface are still a common clinical problem in prosthodontics. The purpose of this study wa...

PURPOSE To compare the clinical results of heparin surface modified (HSM) hydrophilic acrylic intraocular lens (IOL) with those of hydrophobic acrylic IOL. METHODS One hundred patients with cataract were randomized to receive one of acrylic foldable IOLs after phacoemulsification: HSM hydrophilic acrylic IOL (n=50) BioVue3 (BioVue, OII, Ontario, CA, USA) and hydrophobic acrylic IOL (n=50) Sen...

In this paper we present an algorithm for a glass-painting filter. The filter inputs any arbitrary 2D image and converts it into its equivalent glass painted form. The initial image is processed through various nonphotorealistic rendering stages. The major steps involved in the process include – edge detection and refinement, conversion of image into painted form, changing the appearance of the...

A single point viscosity measurement has been proven meaningless in determining the rheological and application properties of a paint. Paints having the same “one point“ viscosity can hove different settling, sag, and leveling properties. These rheological differences are graphically depicted by means of viscosity profiles obtained through the use of low and high shear rate viscometers. A metho...
