A magma which contains greater than 68% silica by weight.

CONT

Rhyolite magma is rich in silicon, potassium and sodium and erupts at temperatures between 700°C and 850°C as an extremely viscous(sticky) magma. Rhyolite magma containing lots of gas bubbles cools to form pumice. Because it is low in iron, rhyolite is normally light-coloured-it may vary from white to pink or brown.

DEF

The smaller body in a co-orbiting star or planet binary.

CONT

During the course of its evolution the primary expands, and its atmosphere may be gravitationally attracted to the secondary, the gas streaming from one star to the other.... So much gas may flow from the primary to the secondary that the secondary eventually becomes the new primary. Sirius, which has a companion that has evolved into a white dwarf, has now reached this state.

"Partner" and "mate" may be encountered as stylistic variants of the more technical term "companion".

Record 11 1993-07-15

English

Subject field(s)
  • Pulp Preparation (papermaking)
OBS

A representative medium-consistency system is shown in Figure 11-19. Pulp from a brown stock washer or decker at about 10-14% consistency is charged with caustic or oxidized white liquor. It is then preheated in a low-pressure steam mixer and pumped through one or more medium-consistency gas mixers to an upflow pressurized reaction tower. Steam and oxygen are added upstream of the medium-consistency mixer or are added directly into it. The reactor bottom may be hemispherical or conical, and the top is equipped with a discharger.... The stock is depressurized through a separator where steam is flashed and small amounts of by-product gases, oxygen and other noncondensibles are released.

Subject field(s)
  • Pulp Preparation (papermaking)
OBS

High-Consistency System. Figure 11-18 shows a representative system where pulp is handled in the 25% to 28% consistency range. Typically, a press is used to raise the feed consistency to about 30%. Fresh caustic or oxidized white liquor along with the magnesium protector is added to the pulp at the discharge of the press. A thick stock pump then transfers the pulp to a fluffer via a feed pipe in which a gas-tight plug is formed. The fluffed pulp flows down the pressurized reactor as a loose bed, while gaseous oxygen is continuously dissolved into the liquid phase and reacted with the pulp.... Oxygen gas is added to either top or bottom to maintain a partial pressure within the 90 to 130 psi range. Relief is taken from the head space at the top of the tower to remove combustibles and other noncondensible gases, and control overall reactor pressure. At the bottom of the tower, the reacted pulp is diluted with post-oxygen filtrate and pumped at about 6% consistency to a blow tank.

DEF

The rapid implosion of a star or other astronomical body from its initial, normal size to a size hundreds of thousands of times smaller.

CONT

’gravitational collapse’ usually refers to the sudden collapse of the core of a massive star at the end of nuclear burning, when its internal gas pressure can no longer support its weight.... The eventual degree of gravitational collapse is determined by the mass that remains. The three most likely end-products(in order of increasing mass) are white dwarfs, neutron stars, and black holes.
