Repeated cycles of chronic intermittent ethanol (CIE) exposure increase voluntary consumption of ethanol in mice. Previous work has shown that extracellular glutamate in the nucleus accumbens (NAc) is significantly elevated in ethanol-dependent mice and that pharmacologically manipulating glutamate concentrations in the NAc will alter ethanol drinking, indicating that glutamate homeostasis play...

The purposes of this study are: (1) determine the color of the twenty shades in the Ivoclar’s Chromascop shade guide, (2) determine the color representation of the shade guide described as coverage error (CE), and (3) compare this shade guide with the Vita Classical and Bioform shade guides. The spectral data was collected using Beckman model DU reflectance spectrophotometer equipped with an in...

A commercial kit from Diagnostica, Inc., Miami Fla., was studied for its ability to detect antibodies to the teichoic acids of Staphylococcus aureus. A comparative study of the Diagnostica counterimmunoelectrophoresis (CIE) system and our gel double-diffusion method was undertaken with 156 serum samples from 142 patients. Included were 25 cases of staphylococcal and non-staphylococcal endocardi...

Hepatitis-B surface antigen was found in 58% of 64 patients with cirrhosis in Iraq using counter immunoelectrophoresis (CIE), radioimmunoassay (RIA), and three commercial haemagglutination tests--Auscell (Abbott Laboratories), Hepatest (Wellcome Reagents Ltd.), and Hepanosticon (Organon Teknika). CIE detected about half as many positives as the other methods; RIA was the most sensitive. The num...

In this paper, we developed a novel approach that provides effective and robust segmentation of color images. It preprocesses an image by converting color information from RGB to CIE L*a*b* color spaces that CIE L*a*b* color spaces can express color in a device-independent way. CIE L*a*b* color space is better suited to digital image manipulations than the RGB space, because it had removed corr...

There are currently five transformation matrices being considered for use in the linear chromatic-adaptation transform in a revision of the CIECAM97s color appearance model. Four of the matrices were developed independently for the purpose of transforming tristimulus values to spectrally sharpened RGB responses. The fifth is the HuntPointer-Estevez transform of CIE tristimulus values to normali...

In this study measurements of color parameters of UHT milk were performed, by using a MOM-color 100 photoelectric tristimulus colorimeter. Colors of UHT milk samples containing 3.2% and 1.6% milk fat, processed under industrial conditions, packed in polyethylene terephtalate (PET) based packages, and stored for 0, 15, 30, 45, 60 and 90 days at ambient temperature (20±5°C) were examined. Results...

We provide three analytical fits to the CIE x̄, ȳ, and z̄ color matching curves commonly used in predictive and spectral renderers as an intermediate between light spectra and RGB colors. Any of these fits can replace the standard tabulated CIE curves. Using tabulated curves can introduce typos, encourage crude simplifying approximations, or add opportunities to download curves from sources featu...

Marine and continental records1 show an abrupt negative shift in carbon isotope values at ~55.8 Myr ago. This carbon isotope excursion (CIE) is consistent with the release of a massive amount of isotopically light carbon into the atmosphere and was associated with a dramatic rise in global temperatures termed the Paleocene–Eocene thermal maximum (PETM). Greenhouse gases released during the CIE,...
