Sequence of events on October 4, 2002
Event State[a] Cazares[b] Merel[c] Magidson[d]
Sexual encounters with Araujo Merel: approx. two weeks prior (Sep 20)
Magidson: approx. two days prior (Oct 2)
Araujo was first confronted by Merel: "We want to know why everybody—you want everybody to fuck you in the ass. Are you a woman or sloppy ass nigga?"
Physical confirmation of anatomy Magidson: suggested "let me feel"
In the bathroom Araujo went to the bathroom alone with Magidson. Merel knocked on the door and asked for information. Magidson opened the door, told Merel that Araujo was not letting him feel her, and closed the door again. Brown went to the bathroom to see if Araujo would be more comfortable with a woman, and conducted a forced inspection. Brown left Araujo inside, and announced that Araujo was a man. Cazares entered the bathroom and prevented Merel from entering to confront Araujo.
Genital exposure Magidson: pulls underwear aside, revealing testicles. Puts Araujo in chokehold multiple times.
Araujo attempts to leave Assisted by Emmanuel, prevented by Magidson and Nabors
Physical violence Two slaps to head from either Merel or Magidson. Araujo begs them to stop: "No, please don't. I have a family." Merel returns with a food can and strikes Araujo hard enough to dent the can. Merel leaves, returns with frying pan and strikes a lighter blow.
Nabors and Cazares leave Cazares: "[We're] going to get some shovels so they can kill that bitch," to group. Privately, to Nabors, he says Araujo told him she had connections to a street gang and offered him money to help her escape.
Nabors and Cazares return Araujo was sitting on a couch, conscious. Merel was holding a dumbbell bar with free weights. Cazares and Nabors: "Knock that bitch out." Magidson punches Araujo twice in the face, then knees her twice in the face, causing her head to fly back and dent the wall.
Merel Cleans the couch after ordering Araujo to get off it.
After Araujo is unconscious Magidson ties Araujo's wrists and ankles. Cazares retrieves a blanket. Magidson, Nabors, and Cazares carry Araujo to the garage. Nabors returns the house to check on Merel, sees Magidson moving the rope up to the upper part of her body.

Power is supplied to the trains through an overhead contact system (OCS), consisting of a messenger wire, which assumes a parabolic shape due to sag, and a contact wire suspended below the messenger wire. The contact wire is nearly parallel to the ground, and supplies traction current to the pantograph of an electric train's. Both the messenger wire and the contact wire are energized with single-phase alternating current at 25kV with a frequency of 60 Hz. This allows the OCS to be used for both Caltrain and future California High-speed Rail service, and this electrical configuration matches that of Amtrak (on the Northeast Corridor) and portions of the New Jersey Transit commuter rail system.[7]

Contact wire height is planned to vary between 16 to 23 feet (4.9 to 7.0 m), depending on overhead clearance required, with the messenger wire another 2 to 5 feet (0.61 to 1.52 m) above that, and pole height will vary between 30 to 50 feet (9.1 to 15.2 m). Nominal clearance under the contact wire will be 23 feet (7.0 m) to accommodate freight and non-electrified passenger rail service. Poles are nominally spaced 180 to 200 feet (55 to 61 m) apart, but can be reduced to 75 feet (23 m) for the tightest-radius bends (just south of San Francisco and just north of San Jose). Typical pole spacing in bends will be 120 to 150 feet (37 to 46 m), and for straight sections of track, maximum spacing is 230 feet (70 m) between poles.[7]

Uneven alignment of columns and rows

edit

There may be a situation where an uneven number of cells may need to be aligned with each other, for instance, a single row may be split into two cells (rows) in one column and three cells (rows) in an adjacent column. If   is the maximum number of cells in a given row, this can be handled by the following procedure:

  1. Set the rowspan to   for any cell in that row that is a single cell.
