By July 2007, 280 e9cuft per year of natural gas was being exported from a processing facility at Melitah, on the Libyan coast, through the Greenstream pipeline to southeastern Sicily.  From Sicily, the natural gas travels to the Italian mainland, and then onwards to the rest of Europe.

WLGP is supplied from production at the Bahr Essalam and Wafa fields, which is processed at the onshore Mellitah treatment plant.

Norris Dam is a hydroelectric and flood control structure located on the Clinch River in Anderson County and Campbell County, Tennessee, United States.  Its construction in the mid-1930s was the first major project for the Tennessee Valley Authority, which had been created in 1933 to bring economic development to the region and control the rampant flooding that had long plagued the Tennessee Valley.  The dam was named in honor of Nebraska Senator George Norris (1861–1944), a longtime supporter of government-owned power in general, and supporter of TVA in particular.  The project infrastructure was listed on the National Register of Historic Places in 2016.

Zhengfa Yanzang (Hànyǔ Pīnyīn: Zhèngfǎ Yǎnzàng; Rōmaji: Shōbōgenzō), known in English as the Treasury of the Correct Dharma Eye or by the Japanese reading of its title, Shōbōgenzō, is a collection of "kōan"s compiled by Dahui Zonggao.  Dahui was a famous popularizer of "kōan"s during the Song Dynasty in China.  Dahui's collection is composed of three scrolls prefaced by three short introductory pieces.  Dahui's work uses the same Chinese characters for its title as the now well known Shōbōgenzō written by the Japanese monk Eihei Dōgen in the thirteenth century.  Upon arriving in China, Dōgen first studied under Wuji Lepai, a disciple of Dahui, which is where he probably came into contact with Dahui's "Zhengfa Yanzang".  In his book "Dogen's Manuals of Zen Meditation", the modern scholar Carl Bielefeldt acknowledges that Dōgen likely took the title from Dahui for his own "kōan" collection, the Shinji Shōbōgenzō, and kept it for his later and now most well-known work, the Kana Shōbōgenzō (usually referred to simply as "the Shōbōgenzō"): Indeed the fact that Dōgen styled his effort "Shōbō genzō" suggests that he had as his model a similar compilation of the same title by the most famous of Sung masters, Ta-Hui Tsung-kao [Dahui Zonggao].  Unlike the latter, Dōgen was content here simply to record the stories without interjecting his own remarks.  A few years later, however, he embarked on a major project to develop extended commentaries on many of these and other passages from the Ch'an literature.  The fruit of this project was his masterpiece—the remarkable collection of essays known as the kana, or "vernacular", Shōbō genzō. J. F.
