Correlated Timing and Spectral Variations of the Soft X-ray Transient Aquila X-1: Evidence for an Atoll classification [PDF]

, 1999
Based on Rossi X-ray Timing Explorer data, we discuss the classification of the soft X-ray transient Aquila X-1 in the Z/atoll scheme, and the relation of its kilohertz quasi-periodic oscillations (kHz QPO) properties to the X-ray colors. The color-color

The effect of different wood varnishes on surface color properties of heat treated wood materials

İstanbul Üniversitesi Orman Fakültesi Dergisi, 2017
This study investigates the effects of different wood varnishes on the surface color properties of heat treated wood. Samples prepared from Oriental beech (Fagus orientalis L.) and Scots pine (Pinus sylvestris L.) are subjected to heat treatment at 190,

Phi-Meson Production at RHIC, Strong Color Fields and Intrinsic Transverse Momenta [PDF]

, 2004
We investigate the effects of strong color fields and of the associated enhanced intrinsic transverse momenta on the phi-meson production in ultrarelativistic heavy ion collisions at RHIC. The observed consequences include a change of the spectral slopes,

Color changes of three different brands of acrylic teeth in removable dentures in three different beverages: An in vitro study [PDF]

Journal of Dental Research, Dental Clinics, Dental Prospects, 2020
Background. The best prosthetic appliances exhibit a high level of similarity to the lost organ. Color should exhibit favorable stability, as a critical factor in the esthetic appearance of dental prostheses and materials used in fabricating prostheses ...

Blue, white, and red ocean planets - Simulations of orbital variations in flux and polarization colors

, 2019
An exoplanet's habitability will depend strongly on the presence of liquid water. Flux and/or polarization measurements of starlight that is reflected by exoplanets could help to identify exo-oceans.

Efficient Colorimetric Fluoride Anion Sensor Based on π-Conjugated Carbazole Small Molecule

Frontiers in Chemistry, 2021
The ability to detect fluoride anions with high selectivity and sensitivity by using the naked eye is crucial yet challenging. In this study, a novel, simple conjugated organic dye, N-tert-butyldimethylsilyl-3,6-diiodocarbazole (CA-TBMDS) was developed ...

The Impact of Bleaching and Brushing with a Novel Purple Versus Charcoal Whitening Toothpaste on the Color of a Discolored Single-Shade Polymeric Resin-Based Restorative Material

Applied Sciences
Background: The aesthetic performance of single-shade polymer-based restorative materials (SPRs) can be compromised by extrinsic stains. Understanding the effects of novel whitening interventions on SPRs is crucial.
