-Alex. It means 3 beads from one end of a joint to the other. In SMAW (stick welding)each bead can be one electrode or many. Interpass temperatures are taken after a pass is complete. In a fillet weld the first layer is also the first pass. The second layer will probably be two passes.

Could power from solar panels be transmitted wirelessly?
Electrical power from solar panels, or any other source, can be transmitted wirelessly, however, not economically nor with great efficiency. Therefore I would say that it is impractical to do so on a large scale. One such scheme has been described would gather solar energy using orbiting arrays then sending it to receivers on earth's surface as a narrow beam of microwaves. There are solar powered wireless charging devices for small electronics that are available.

Why does the Alaskan pipeline zigzag?
The temperature difference of minus 70 degrees F and 145 degree oil filled pipe meant that a section of pipe would expand in length by 18 inches. When the temperature changes the pipe has to go somehere so the zigzag converts linear expansion into a sideways movement. Extreme zigzags were added where it crosses the Denali fault area to compensate for earthquake movement. The zigzag added 11 miles of pipeline to the project.
Structural geologists look at features in rock caused by deformation, that is, by the action of forces acting on and within the earth's crust. These structures include faults and folds, which significantly affect the strength of rock and must be considered in the construction of tunnels, buildings, dams and other engineering projects that rely on that rock for their foundation.

How toluene can be separated from acetonitrile without using an entrainer?

Flaps are mounted on the aft or trailing edge of wings. When extended, they change the aerodynamic shape of the wing to produce greater lift at slower speeds. Slats are simply a flap on the leading edge of a wing rather than the trailing edge, increasing lift in a similar manner to a flap. The Slats actually allow the aircraft to obtain greater angle of attack. If too much Flaps are mounted on the trailing edge, this may want to cause the wing to pitch nose down. The Slats is a way to counter-act this force as it tends to cause the nose to pitch upwards. Because both the flap and slat offer great advantages in generating high lift, most aircraft today use a combination of both to maximize the lift coefficient as well as the maximum angle of attack while minimizing the effect of pitching moment.
