Surface Microhardness and Flexural Strength of Colored Zirconia

Advanced Materials Research, 2010
The surface microhardness and flexural strength of colored zirconia were examined. Two groups of zirconia disks (1mm thick, 20mm in diameter) within 5 disks each were shading with the same coloring liquids IL2 (Vita Classic-scale) when another group of 5 disks measured in no color.

Color image watermarking with adaptive strength of insertion

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
The paper presents a watermarking technique, specific to color images. The insertion and the detection are based on the 2D discrete wavelet transform, applied on each color component. Three color vectors are extracted from the wavelet coefficients. The insertion consists of modifying one vector for each location, with regard to the bit value and the ...

Affect Aroused by Color, a Function of Stimulus Strength

Journal of Projective Techniques and Personality Assessment, 1966
Abstract The study investigated the effects of stimulus strength of color and degree of autism on the response to color, as it reflects an affective or cognitive process. Subjects were 30 male schizophrenics, 15 high autistic and 15 low autistic. Color was measured by selected cards from the HIT containing both high and low stimulus strength. Responses

Solution ionic strength effect on gold nanoparticle solution color transition

Talanta, 2006
Unmodified and modified gold nanoparticles are proposed as sensors using the red to blue transition as an indicator. This work indicates that ionic content is an important variable to track in analytical samples and during the sensor fabrication processes.

The Effect of Light Color on Muscular Strength and Power

Perceptual and Motor Skills, 2008
The purpose of this study was to assess the effect of the color of light in a room on muscular strength and power. A convenience sample of 18 men ( M age = 20.4 yr., SD = 1.2) performed a modified Wingate Anaerobic Cycle Test for muscular power and a hand grip strength test in each of the following conditions: red, blue, and white (neutral) ambient ...

Compressive strength–color change relation in mortars at high temperature

Cement and Concrete Research, 2004
Changes in materials' physical, chemical and mechanical properties have to be known to decide whether the buildings exposed to high-temperature effect will be repaired or demolished. In order to carry out the effects of fire and extinguishing on the properties of concrete, mortars with and without silica fume were exposed to different temperatures ...
