White break

The first grade of the fire lasts until the white appears, and takes place with one lamp in three months. The next takes place until the white breaks up, with two wicks in the space of three months. The third until the white is fixed the fourth until the end of three months. 

Crazes occur perpendicular to the stress direction shortly before a destructive break. They may be up to 100 pm long and up to 10 pm wide. Crazes are not hairline cracks, that is, they are not totally void between the break surfaces, in contrast to what are known as white breaks. 

If a dilute acid is added to this solution, a white gelatinous precipitate of the hydrated tin(IV) oxide is obtained. It was once thought that this was an acid and several formulae were suggested. However, it now seems likely that all these are different forms of the hydrated oxide, the differences arising from differences in particle size and degree of hydration. When some varieties of the hydrated tin(IV) oxide dissolve in hydrochloric acid, this is really a breaking up of the particles to form a colloidal solution—a phenomenon known as peptisation. 

Ordinary tin is composed of nine stable isotopes 18 unstable isotopes are also known. Ordinary tin is a silver-white metal, is malleable, somewhat ductile, and has a highly crystalline structure. Due to the breaking of these crystals, a "tin cry" is heard when a bar is bent. 

Potassium biduoride crystals may break down to a fine white powder that is readily airborne. In this form, the salt is quite irritating to the nasal passages, eyes, and skin. Therefore, the hands and eyes should be protected and acid dust masks should be worn while handling, as an acid duoride KHF2 can cause superficial hydroduoric acid-type bums. Areas of skin that have been in contact with potassium biduoride should be washed as soon as possible with mildly alkaline soaps or borax-containing hand cleaners. If there has been contact with the eyes, they should be washed well with water and a physician should be consulted. 

Two classes of grinding equipment are used to prepare dispersions. The first, the coUoid mill, does not effect a particle size reduction but does break down aggregates of fine particles. CoUoid mills are used for such powders as clays, precipitated whiting, etc. Sometimes these mills are used to process zinc oxide but for dipped mbber products that is not satisfactory. 

A third screening smoke-type is white phosphoms [7723-14-0] (WP), P (see Phosphorus and THE phosphides), which reacts spontaneously with air and water vapor to produce a dense cloud of phosphoms pentoxide [1314-56-3]. An effective screen is obtained as the P2O5 hydrolyzes to form droplets of dilute phosphoric acid aerosol. WP produces smoke in great quantity, but it has certain disadvantages. Because WP has such a high heat of combustion, the smoke it produces from bulk-filled munitions has a tendency to rise in pillarlike mass. This behavior too often nullifies the screening effect, particularly in stiU air. Also, WP is very brittle, and the exploding munitions in which it is used break it into very small particles that bum rapidly. 

Physical Properties. The egg is composed of three basic parts shell, whites (albumen), and yolk. Each of these components has its own membranes to keep the component intact and separate from the other components. The vitelline membrane surrounds the yolk, which in turn is surrounded by the chala2iferous layer of albumen, keeping the yolk in place. Egg white (albumen) consists of an outer thin layer next to the shell, an outer thick layer near the shell, an inner thin layer, and finally, an inner thick layer next to the yolk. Thick layers of albumen have a higher level of ovomucin in addition to natural proportions of all the other egg white proteins. This ovomucin breaks into shorter fibers when the egg white is blended on a high speed mixer (3), or when the egg white ages. Viscosity is gready reduced when the egg white is blended in this way. 

Yolk comes from breaking machines at 45% or greater, and this is standardized to 43.5% soHds by adding mix and whites to the Hquid. USDA standards do not allow going below 43.0% soHds for yolk. SoHds to which product is standardized depends on customer specifications. 

Acetylenylpyrazoles were tested on antiarrhythmia aetivity (84MI1). The use 5 mg/kg of eompound 105 inhibited the development of aeonitine arrhythmia in 50% of animals. However, it failed to prevent heart arrhythmia. A dose of 15 mg/kg prevented or substantially inhibited the break of arrhythmie aetivity in about 75% of white rats. 

I applied my music background to a liquor background, Mr. Storm said. Like breaking a record—instead of D.J.s, I used bartenders in the Hamptons, then on the flip side, parties at urban events. Though he qualified urban by saying, We know that urban is not black, white or Latino, Mr. Storm explained. The buzz now is in the hip-hop and Latin markets. ... 

Despite more than 200 years of sulfur research the chemistry of elemental sulfur and sulfur-rich compounds is still full of white spots which have to be filled in with solid knowledge and reliable data. This situation is particularly regrettable since elemental sulfur is one of the most important raw materials of the chemical industry produced in record-breaking quantities of ca. 35 million tons annually worldwide and mainly used for the production of sulfuric acid.
