Yellow and White

Vaseline A trade name for soft paraffin. Yellow and white semi-solid, partly translucent mixtures of hydrocarbons of the paraffin series ranging from CijHji to C2oH42- Obtained from the high-boiling fractions of petroleum... 

A number of controls are provided to enable the user to tailor the colour, scale and orientation of the displayed image to highlight details of interest. Two types of colour map are available. The Default colour map is a cold-to-hot scheme in which with cold colours such as blue used for low amplitudes and hot colours such as red, yellow and white used for high amplitudes. The Mono colour map uses intensities of red, from black upwards, to indicate increasing amplitude. 

Production costs for biodiesel from soybean oil exceeds 2.00 per gal ( 0.53 per 1), compared to 0.55 to 0.65 per gal ( 0.15 to 0.17 per 1) for conventional diesel. The main cost in biodiesel is in the raw material. It takes about 7.7 lb (3.5 kg) of soybean oil valued at about 0.25 per lb (0.36 per kg) to make 1 gal (3.81) of biodiesel. Waste oils, valued at 1 per gal ( 3.79 per 1) or less, have the potential to provide low feedstock cost. However, much waste oil" is currently collected, reprocessed as yellow and white greases, and used for industrial purposes and as an animal feed supplement. Production of biodiesel...

Apart from colour, wavelengths evoke another sensation to the physicist the notion of hot or cold. For tint and temperature are related. When an object is heated at the forge, it changes from black (lack of colonr), through red, yellow and white to pale blue.

The practical recipes of the pseudo-Democritus differ only from the Theban papyri in their less simple and plain directions. They are the same in their intentions of imitating gold and silver by yellow and white alloys of copper, lead, tin, mercury and arsenic by colored mixtures or varnishes or stains to be superficially applied to give a surface resemblance to gold or silver and the materials... 

Interest in pteridines began with Frederick G. Hopkins, who in 1891 started his investigation of the yellow and white pigments of butterflies. Almost 50 years and a million butterflies later, the structures of the two pigments, xanthopterin and leucopterin (Fig. 15-17), were established.339 These pigments are produced in such quantities as to suggest that their synthesis may be a means of deposition of nitrogenous wastes in dry form. 

In Activity 9.2 it is assumed that lead ions are not found in modem paint pigments, but this is not entirely the case. Even though lead-based paints are prohibited from use in house painting, lead compounds still appear in some art paints. Some red, yellow, and white pigments contain lead compounds. Hazards in art are discussed in Chapter 10. 

Older paints, especially yellow and white paints, usually contained lead ions. Newer paints less frequently contain lead ions. If much lead is detected in paint chips removed from a painting, then it can be speculated that the painting is old and an original work of art. 

A solid waste containing yellow and white phosphorus may become characterized as a hazardous waste when subjected to testing for reactivity as stipulated in 40 CFR 261.23 and, if so characterized, must be managed as a hazardous waste (40 CFR 261.23 [7/1/90]). dGroup D = Not classifiable as to carcinogenicity in humans... 

Lovibond tintometer color can also be measured using objective automated instruments. In one version, the intensities of three light beams (red, yellow and white) transmitted by the oil are measured by photoelectric cells, and the results displayed as red and yellow color readings. The white light beam acts as a reference beam, and allows compensation for variation in the intensity of the light source (Rossell, 1986). AOCS Official Method Cc 13j 97 (Firestone, 1998) specifies how an automated tintometer should be used. However, this standard is valid only for refined oils. 

The Senior says At first it is dissolved with its water, but ultimately with fire, even as fruit in spring requires moisture, and afterwards warmth to mature it. The first solution is recognised when the body, together with the water, becomes completely yellow, or an intermediate colour between yellow and white.

Leaves duU gray-green or silvery. Cause Thrips. Leaves may turn brown and papery. These tiny, spiderlike insects can barely be seen with the naked eye. To check for thrips, tap a leaf over a white paper and look for moving specks. Trap thrips with sticky traps or spray plants with insecticidal soap to control them. Try blue, yellow, and white sticky traps placed just above plant height to see which color works best. 

If leaf tips are distorted or brown, and leaves are stippled with white, look for onion thrips. Heavy infestations cause plants to wither and turn brown. Adults are tiny, slender, yellow to brown, rapidly moving, winged insects. The larvae can barely be seen with the naked eye. Thrips thrive in hot, dryvjveather. Trap them with sticky traps hung st above plant level. Try blue, yellow, and white traps to see which work best. Treat plants with insecticidal soap or a commercial pyrethrin spray or dust to control severe infestations. 

Parsley oil is used in medicine. Crystalline apiole, yellow and white apioles, and oil of parsley when given intravenously exert an equal degree of toxicity, the essential oil being the most regular in its action. Bull, Sci. Pharm. 1910 17, 7, via Y.B. ofPharm. 1910, 207)... 

This family includes coral snakes, cobras, mambas, and kraits. In the United States, Elapidae are responsible for 1-2% of poisonous snakebites. The incidence of envenomations is greater in some other parts of the world. Examples of coral snakes commonly found in the United States are the eastern coral snake, the Sonoran coral snake, and the Texas coral snake. Coral snakes are smaller than pit vipers. They do not have facial pits, and the head is rounded, as are the pupils. Eangs are 2mm and fixed to the jaw. Coral snakes are also more brightly colored, with bands of black and red, separated by yellow and white bands. Coral snakes are timid, nocturnal creatures.

Petrolatum is usually a soft product containing approximately 20% oil and melting between 38°C (100°F) and 60°C (140°F). Petrolatum or petroleum jelly is essentially a mixture of microcrystalline wax and oil. It is produced as an intermediate product in the refining of microcrystaUine wax or compounded by blending appropriate waxy products and oils. Petrolatum colors range from the almost black crude form to the highly refined yellow and white pharmaceutical grades. 

The infrared (IR) spectra of PPSe and PPTe were recorded with the samples dispersed in cesium iodide using Fourier transform techniques. Between 4000 and 600 cm-- -, the IR spectra of PPSe (both yellow and white forms) and PPTe are superimposable on that of PPS. Below 600 cm- -. bands at 550 and 475 cm- - in PPS are found at 500 and 475 cm- - in PPSe (both forms) and at 489 and 465 cm- - in PPTe. Other relevant features between 600-200 cm- -are discussed below.
