Lightly pigmented skin Persistent area of reddened skin. 

P. O.13 sample reaches only step 4. Transparent P.O.34 colorations in rigid PVC are even more resistant to light. Pigment concentrations of less than ca. 0.1% are likewise unsuitable, due to the necessity to avoid blooming. The pigment is also used in vinyl floor coverings and in cable insulations. 

Lacquer A rapid-drying coating by evaporation of solvent only. It will redissolve in the solvent, and it may be lightly pigmented. 

The hardened, light stable, lightly pigmented food contact materials are not susceptible to stress cracking, but are resistant to alcohols, ethers, hydrocarbons, fats, and can be used with weak acids and boiling water. Typical applications are beverage containers and silos for foodstuffs. 

Colorants are typically defined as pigments and dyes that, when added to plastics, define a specific color. The subject of colorants has been discussed in numerous books and papers. However, in the context of this chapter, a dye is defined as a substance that is soluble in the resin system and produces color only by the absorption of light and no scattering of light. Pigments are not soluble in the resin system and therefore must be mixed into the resin by one of many dispersion processes. Factors such as pigment particle size and ease of mixing or dispersion directly influence their... 

Grade V Central, lightly pigmented, pearl-like, opaque mass surrormded by smaller clumps of pigment. 

Pigmentation Heavy, usually both ventrally and dorsally Medium-heavy, usually only dorsally Unpigmented or lightly pigmented... 

The intradermal parenteral route is an injection that is given slightly below the surface of the skin where the medication is not absorbed into the bloodstream. The area of the skin is hairless, lightly pigmented, and thinly keratinized, providing a clear view of the site. The intradermal parenteral route is used to determine if there is a reaction to the medication, which is signified by a blister (wheal) on the injection site. 

We can, as a general rule, divide inorganic solids into 2 classes those that absorb light (pigmented) and those that emit light (phosphors and solid state lasers). In both cases, we add controlled amounts of a transition metal ion to control the absorption and/or emission properties of that solid. At this point, it should be apparent that emission refers to ... 

In the retina, there are two kinds of light-sensing cells, rods and cones, that convert incoming photons into neuronal action potentials. When cones are activated by photons of light, pigment molecules change shape and produce electrical action potentials that pass information throughout the brain. 

Intradermal injections are given in hairless areas of the body that are lightly pigmented and thinly keratinized so that the nurse can observe any reaction to the medication. These are ...
