The electrical resistance of the coil, the voltage output of the device, the airflow of the atomizer and the efficiency of the wick all affect the vapor coming from the atomizer. [83] They also affect the vapor quantity or volume yielded. [83] Atomizer coils made of kanthal usually have resistances that vary from 0.4Ω to 2.8Ω. [83]
The A.C. Nielsen company, which continues to measure television ratings today, took over American radio's ratings beginning with the 1949–50 radio season and ending in 1955–56. [40] During this era, nearly all of radio's most popular programs were broadcast on one of three networks: NBC Red, NBC Blue, or CBS' Columbia network.

A 2015 review found the effectiveness of Essure is unclear due to the low quality of evidence. [18] With perfect use another review found evidence of a 99.8% effective based on 5 years of follow-up.
MSD Ignition was the first company in the world to experiment with Multiple Spark Discharge for the ignition system of internal combustion engines in 1970. The idea was first proposed by a group of engineers working on the White Sands Missile Range in southern New Mexico.
