In the guppy Poecilia reticulata, males exhibit orange spots on their body and tail, and the orange spot patterns are often criteria of female mate choice. The orange spot coloration of the males is determined by the intake of algae, a natural source of carotenoids. Therefore, it is considered that males exhibiting conspicuous orange coloration possess high algal-foraging ability. In the presen...

The computer graphic simulation of a common spray painting artifact, called orange peel, is discussed. Orange peel distorts surface reflections and is commonplace in product design applications. The orange peel measurements from a standard industrial instrument are used to construct a height field, and this surface is rendered using traditional normal mapping techniques. Comparisons are made be...

Background: Vitamin A (VA) and zinc deficiencies are prevalent. Maize is a common staple, and milling affects nutrient and nutrient-modifier profiles.Objective: We investigated the interaction of maize milling methods (i.e., whole grain compared with refined) in male Mongolian gerbils aged 29-35 d with conventionally bred provitamin A-biofortified (orange) or white maize on VA and zinc status.M...

Fifteen collaborating laboratories were sent 9 samples of citrus juice mixtures as blind duplicates for determination of naringin and neohesperidin by liquid chromatography. Two sample pairs were 100% orange juice and did not contain any naringin or neohesperidin. The remaining 7 sample pairs contained naringin at levels ranging from 3.9 to 46.5 ppm and neohesperidin at levels ranging from 0.14...

The use of digitonin to permeabilize the plasma membrane of Trypanosoma brucei procyclic and bloodstream trypomastigotes allowed the identification of a non-mitochondrial nigericin-sensitive Ca2+ compartment. The proton ionophore carbonyl cyanide p-trifluoromethoxyphenylhydrazone (FCCP) was able to cause Ca2+ release from this compartment, which was also sensitive to sodium orthovanadate. Prein...

Electrical heating of food products provides rapid and uniform heating, resulting in less thermal damage to the product. The objective of this research was to examine the effects of ohmic heating on the stability of orange juice with comparison to conventional pasteurization. During storage at 4 degrees C, degradation curves of ascorbic acid followed a linear decrease pattern in both ohmic-heat...

nano-cus powders were synthesized with chemical solution method. xrd and sem and spectrophotometry were used for characterization of the cus powders. xrd analysis indicated that tetragonal cus was the main phase with particle size of 16.2nm and little cu2s phase was present. scanning electron microscopy (sem) analysis revealed that powder was plate like and had very little aspect ratio in morph...

A rare-earth free red emitting β-Zn3B2O6:Mn(2+) phosphor was prepared by a solid-state reaction method. The crystal structure, photoluminescent and cathodoluminescent properties of β-Zn3B2O6:Mn(2+) were systematically investigated. The absorption and photoluminescence excitation spectra confirm that β-Zn3B2O6:Mn(2+) matches the UV LED chip. Under UV light and low-voltage electron beam excitatio...
