MDMA

MDMA (contracted from 3,4-methylenedioxy-methamphetamine) is a psychoactive drug of the substituted methylenedioxyphenethylamine and substituted amphetamine classes of drugs that is consumed primarily for its euphoric and empathogenic effects. Pharmacologically, MDMA acts as a serotonin-norepinephrine-dopamine releasing agent and reuptake inhibitor.

MDMA has become widely known as ecstasy (shortened to "E", "X", or "XTC"), usually referring to its tablet form, although this term may also include the presence of possible adulterants. The UK term "Mandy" and the US term "Molly" colloquially refer to MDMA in a crystalline powder form that is thought to be free of adulterants. In the media "Molly" can sometimes also refer to the related drugs methylone, MDPV, mephedrone or any other of the pharmacological group of compounds commonly known as bath salts.

Possession of MDMA is illegal in most countries. Some limited exceptions exist for scientific and medical research. In 2013 between 9 and 28 million people used ecstasy (0.2% to 0.6% of the global population between the ages of 15 and 65). This was broadly similar to the number for cocaine, substituted amphetamines, and opioids, but far fewer than the number of cannabis users. It is taken in a variety of contexts and is commonly associated with dance parties, raves, and electronic dance music.

Cement

A cement is a binder, a substance that sets and hardens and can bind other materials together. The word "cement" can be traced back to the Roman term opus caementicium, used to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder. The volcanic ash and pulverized brick supplements that were added to the burnt lime, to obtain a hydraulic binder, were later referred to as cementum, cimentum, cäment, and cement.

Cements used in construction can be characterized as being either hydraulic or non-hydraulic, depending upon the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster).

Non-hydraulic cement will not set in wet conditions or underwater; rather, it sets as it dries and reacts with carbon dioxide in the air. It can be attacked by some aggressive chemicals after setting.

Hydraulic cements (e.g., Portland cement) set and become adhesive due to a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in water and safe from chemical attack. This allows setting in wet condition or underwater and further protects the hardened material from chemical attack. The chemical process for hydraulic cement found by ancient Romans used volcanic ash (activated aluminium silicates) with lime (calcium oxide).

Cement (novel)

Cement (Russian: Цемент) is a Russian novel by Fyodor Gladkov (1883–1958). Published in 1925, the book is arguably the first in Soviet Socialist Realist literature to depict the struggles of post-Revolutionary reconstruction in the Soviet Union.

The protagonist, Gleb Chumalov, is a returning Red Army soldier hero who after the Russian Civil War comes back to a hometown in painful transition and to its cement factory being reorganized for the massive new Soviet effort. His wife, Dasha, plays the role of the Soviet "new woman," and Gleb finds he cannot easily pick up the threads of their old relationship. The novel is Gladkov's best known work because of its portrayal of the sociological effects of early Communism, especially after the sexes are suddenly decreed equal in the labor force of the local cement factory.

Plot

A Red Soldier returns home from the war victorious, eager to return to his wife, comrades, and factory, only to find out that the Revolution is in shambles, and that the country is in famine despite food rations. When he left three years earlier, Revolution was in the air. Now his wife's heart has hardened, his comrades no longer recognize him, and the factory is deserted, stripped bare by the starving citizens. Nearly everyone has abandoned the Revolution, and icons of the revolution collect dust, neglected. Only a few have remained loyal to the Revolutionary ideals. These few serve as examples of the ideal socialist citizen, but there are too few of them and a socialist state requires the masses to operate the machine of the socialist cause.
