Creosote removed; the "heavy oil", which sinks; and the "anthracene oil", which when cold is mostly solid and greasy, of a buttery consistence. Creosote refers to the portion of coal tar which distills as "heavy oil", typically between 230–270 °C, also called "dead oil"; it sinks into water but still is fairly liquid. Carbolic acid is produced in the second fraction of distillation and is often distilled into what is referred to as "carbolic oil". Commercial creosote will contain substances from six groups. The two groups occur in the greatest amounts and are the products of the distillation process—the "tar acids",
Name-letter effect so-called "I-algorithm"), as originally recommended and named by LeBel and Gawronski). In her meta-analysis, Hoorens does not recommend a specific algorithm as little is known about how name-letter preference scores obtained from different algorithms relate to the most important psychometric quality of all, validity. The algorithms are typically applied to initials only, but can be used for all name letters. Stieger, Voracek, and Formann recommend that the task be administered twice, that the effects be calculated separately for first-name initial and last-name initial, that the task be accompanied with the birthday-number task, and that the instructions focus on liking rather
