In this paper, the spectral dimensions of two sets of samples including 457 black and 84 white fabrics are compared. White fabrics are treated with variety of fluorescent whitening agents and the blacks are fabrics that dyed with different combinations of suitable dyes and pigments. In this way, the reflectance spectra of blacks as well as the total radiance factors of whites are compressed in ...
Monolithic phosphor-free two-color gallium nitride (GaN)-based white light emitting diodes (LED) have the potential to replace current phosphor-based GaN white LEDs due to their low cost and long life cycle. Unfortunately, the growth of high indium content indium gallium nitride (InGaN)/GaN quantum dot and reported LED's color rendering index (CRI) are still problematic. Here, we use flip-chip ...
Color filters are widely used in color displays, optical measurement devices, and imaging devices. Conventional color filters have usually only one fixed output color. However developing active color filters with controllable color output can lead to more compact and sophisticated color filter-based devices and applications. Recent progress in nanotechnology and new knowledge of the interaction...
Ammonia is a weak base that can be used as an swelling agent on wool fibres before dyeing. In this study the pretreatment of wool with ammonia in different percent solutions (5, 10, 15, 20) is carried out, and its effect on dye-ability of wool by natural dyes such as madder, walnut shell, pomegranate peel, vine leaf, white and red onion skin, is analyzed. Also the effects of temperature, length...
OBJECTIVE There has been a growing interest in finding plants with biological active ingredients for medicinal application. MATERIALS AND METHODS Three colors of petals of Althaea officinalis (A. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. RESULTS The reddish pink flowers of A. officinalis have more antioxidan...
Introduction: In the contemporary era, suicide rates have markedly increased in society by increasing the population, expanding the industry and machine life, and the prevalence of the various types of mental and emotional problems.

Figures submitted electronically as separate PostScript files containing color usually appear in color in the online journal. However, all figures will appear as grayscale images in the printed journal unless the color figure authorization form has been received and you have agreed to pay the necessary charges. For figures that will be color online but grayscale in print, please insure that the...
Rice grains are the main crops consumed by more than half of world’s population. White rice contains carbohydrates, while pigmented varieties nutritious, with bioactive compounds that can potentially prevent pro-inflammatory diseases like diabetes and hypertension. Broken is produced in large quantities as a cheap by-product milling; however, its nutraceutical contents have not been identified....
