Light Transmission through Three Types of Translucent Zirconia
Objective: Zirconia cores have limited light transmittance and data are scarce on light transmission through zirconia cores with and without the veneering ceramic. Methods: In this in vitro study, Disc-shaped specimens (11.5 mm in diameter and 0.4 (0.05) mm in thickness) were fabricated of three types of zirconia namely Mamut, Heany and ZirkonZahn (n=5). A disc-shaped specimen (11.5 mm in d...

متن کاملNormalized Model of Traffic Light Traits Based on Colored Pixels
Nowadays, because of the growing numbers of vehicles on streets and roads, the use of intelligent controlsystems to improve driving safety and health has become a necessity. To design and implement suchcontrol systems, having information about traffic light colors is essential. There are the wide variety oftraffic lights in terms of light intensity and color. Therefore it seems that design and ...
متن کاملTranslocation in colored light.
The translocation of (14)C-photosynthate in detached blades of sugarcane was studied under illumination from red, green, blue, and cool-white fluorescent lamps; under far-red illumination from the sun, and from incandescent lamps; and in total darkness.The percentage of basipetal translocation and the accumulation against the concentration gradient were stimulated by light from the red or blue ...
متن کاملLight transmission through a translucent fiber post.
This study is a quantitative assessment of the luminous energy transmitted through different translucent fiber posts. After embedding the posts in black resin, the blocks were submitted to sequential cuts in a precision machine, and depths of 16 mm, 12 mm, 8 mm, and 4 mm were assessed for light transmission with a digital photometer. The quantitative analysis showed significant differences betw...
