PSA XU engine
The PSA XU is a family of internal combustion engines used in Citroën and Peugeot automobiles. It became the dominant mid-size engine in Peugeot and Citroën products through the 1980s and 1990s.
The XU design was introduced in 1981 with the Peugeot 305. It was a SOHC or DOHC straight-4 design with two or four valves per cylinder, using petrol as fuel. It was applied transversely in front wheel drive vehicles only, tilted by 30°. Displacement ranged between 1580 and 1998 cc, and all production XU gasoline engines had a bore of 83 mm (3.3 in) or 86 mm (3.4 in). The engine uses in all models aluminium cylinder head. All models blocks are made, except XU10, in cast aluminium alloy with removable cast iron wet cylinder liners. XU10 blocks are made in cast iron, with bores machined directly in the block, without removable cylinder liners. Its first Citroën application was on the Citroën BX in 1983, where it appeared in 1580cc format.
The XU was replaced by the more modern EW/DW family.

Psalms
The Book of Psalms, Tehillim in Hebrew (תְּהִלִּים or תהילים meaning "Praises"), commonly referred to simply as Psalms or "the Psalms", is the first book of the Ketuvim ("Writings"), the third section of the Hebrew Bible, and a book of the Christian Old Testament. The title is derived from the Greek translation, ψαλμοί psalmoi, meaning "instrumental music" and, by extension, "the words accompanying the music." The book is an anthology of individual psalms, with 150 in the Jewish and Western Christian tradition and more in the Eastern Christian churches. Many of the psalms are linked to the name of King David, although his authorship is not accepted by modern Bible scholars.
Structure
Benedictions
The Book of Psalms is divided into five sections, each closing with a doxology (i.e., a benediction) – these divisions were probably introduced by the final editors to imitate the five-fold division of the Torah:
Pacific Southwest Airlines Flight 1771
Pacific Southwest Airlines flight 1771 was a commercial flight that crashed near Cayucos, California, United States, on December 7, 1987, as a result of a murder–suicide by one of the passengers. All 43 people on board the aircraft died, five of whom were shot to death before the plane crashed, including the two pilots. The man who caused the crash, David A. Burke, was a disgruntled former employee of USAir, the parent company of PSA.
The incident
USAir had recently purchased Pacific Southwest Airlines. Burke, a ticket agent, had been recently terminated by USAir for petty theft of $69 from in-flight cocktail receipts and had also been suspected of other theft including receipts totaling thousands of dollars. After meeting with Ray Thomson, his manager, in an unsuccessful attempt to be reinstated, Burke purchased a ticket on PSA flight 1771, a daily flight from Los Angeles to San Francisco. Thomson was a passenger on the flight, which he regularly took for his daily commute from his workplace at LAX to his home in the San Francisco Bay Area.
