In December 2006, Robert "Evel" Knievel sued West for trademark infringement in West's video for "Touch the Sky". Knievel took issue with a "sexually charged video" in which West takes on the persona of "Evel Kanyevel" and attempts flying a rocket over a canyon. The suit claimed infringement on Knievel's trademarked name and likeness. Knievel also claimed that the "vulgar and offensive" images depicted in the video damaged his reputation. The suit sought monetary damages and an injunction to stop distribution of the video. West's attorneys argued that the music video amounted to satire and therefore was covered under the First Amendment. Just days before his death in November 2007, Knievel amicably settled the suit after being paid a visit from West, saying, "I thought he was a wonderful guy and quite a gentleman."

Analysis of lighting quality particularly emphasizes use of natural lighting, but also considers spectral content if artificial light is to be used. Not only will greater reliance on natural light reduce energy consumption, but will favorably impact human health and performance. New studies have shown that the performance of students is influenced by the time and duration of daylight in their regular schedules. Designing school facilities to incorporate the right types of light at the right time of day for the right duration may improve student performance and well-being. Similarly, designing lighting systems that maximize the right amount of light at the appropriate time of day for the elderly may help relieve symptoms of Alzheimer's Disease. The human circadian system is entrained to a 24-hour light-dark pattern that mimics the earth's natural light/dark pattern. When those patterns are disrupted, they disrupt the natural circadian cycle. Circadian disruption may lead to numerous health problems including breast cancer, seasonal affective disorder, delayed sleep phase syndrome, and other ailments.
What happens to the natural carcidan cycle when light-dark patterns are disrupted?

At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.
When was a new sytle of carved top and back construction mandolins created?
