LP record

The LP (long play), or 33 ¹⁄₃ rpm microgroove vinyl record, is a format for phonograph (gramophone) records, an analog sound storage medium. Introduced by Columbia Records in 1948, it was soon adopted as a new standard by the entire record industry. Apart from relatively minor refinements and the important later addition of stereophonic sound capability, it has remained the standard format for vinyl albums.

Format advantages

At the time the LP was introduced, nearly all phonograph records for home use were made of an abrasive (and therefore noisy) shellac compound, employed a much larger groove, and played at approximately 78 revolutions per minute (rpm), limiting the playing time of a 12-inch diameter record to less than five minutes per side. The new product was a 12- or 10-inch (30 or 25 cm) fine-grooved disc made of vinyl and played with a smaller-tipped "microgroove" stylus at a speed of 33 ¹⁄₃ rpm. Each side of a 12-inch LP could play for more than 20 minutes. Only the microgroove standard was truly new, as both vinyl and the 33 ¹⁄₃ rpm speed had been used for special purposes for many years, as well as in one unsuccessful earlier attempt to introduce a long-playing record for home use.

APT (film)

APT (Hangul: 아파트; RR: Apateu) (released as 9:56 in Singapore) is a 2006 South Korean horror film, directed, produced, and written by Ahn Byeong-ki and starring Ko So-young. It is based on a comic by Kang Full. The name APT is from the English word meaning apartment. The film had 644,893 admissions nationwide.

Plot

Se-jin Oh, a lonely young career woman, lives in a high-rise apartment building in a Seoul suburb, and sometimes watches her neighbors through binoculars for amusement. Taking the subway home one night near Christmas, a woman dressed in red throws herself in front of the train, attempting to drag Se-jin with her. The dead woman haunts Se-jin, though she doesn't know it. However, she does notice that the lights across the way flicker mysteriously at exactly 9:56pm every night—often accompanied by an apparent suicide.

Se-jin is befriended by Yoo-yeon, a wheelchair-bound woman abused by her caregivers, several of whom are among the victims. Yoo-yeon gives Se-jin a puzzle cube, noting it can help to forget the pain for a while. Se-jin attempts to influence her neighbors, begging them to not turn their lights off before 10 pm. This puts her in conflict with police detective Yang, who learns that many of the victims have identical keys to an apartment. The apartment that matches the key, 704, is Yoo-yeon's -- but Yang finds the resident is Shin Jung-soo, a social recluse with long black hair, who attacks Yang, but denies having committed any murders.

6-APT

6-(2-Aminopropyl)tetralin (6-APT), also sometimes called tetralinylaminopropane (TAP), is a drug of the amphetamine class which acts as a selective serotonin releasing agent (SSRA). It has IC₅₀ values of 121 nM, 6,436 nM, and 3,371 nM for inhibiting the reuptake of serotonin, dopamine, and norepinephrine, respectively. Though it possesses an appreciable in vitro profile, in animal drug discrimination studies it was not found to substitute for MMAI or amphetamine and to only partially substitute for MBDB. This parallels Alexander Shulgin's finding that EDMA (the 1,4-benzodioxine analogue of 6-APT) is inactive, and appears to indicate that the pharmacokinetics of both EDMA and 6-APT may not be favorable.
