To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papersnot to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is separated from the cellulose fibres?
Ah, so.. lignin

On December 30, 1922, the First Congress of the Soviets of the USSR approved the Treaty on the Creation of the USSR, by which Russia was united with the Ukrainian Soviet Socialist Republic, Byelorussian Soviet Socialist Republic, and Transcaucasian Soviet Federal Socialist Republic into a single federal state, the Soviet Union. Later treaty was included in the 1924 Soviet Constitution,[clarification needed] adopted on January 31, 1924 by the Second Congress of Soviets of the USSR.

Ah, so.. First Congress of the Soviets of the USSR

Einstein partially advocates Mach's principle in that distant stars explain inertia because they provide the gravitational field against which acceleration and inertia occur. But contrary to Leibniz's account, this warped space-time is as integral a part of an object as are its other defining characteristics, such as volume and mass. If one holds, contrary to idealist beliefs, that objects exist independently of the mind, it seems that relativistics commits them to also hold that space and temporality have exactly the same type of independent existence.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How does Einstein advocate Mach's principle?
Ah, so..
