The underlying discrimination technique has been established by modelling 222Rn and 220Rn diffusion into a pin-hole chamber and validating the same by carrying out experiments in a test chamber.
The operant chambers were provided (on a same wall) with two nose-poking holes, two chamber lights (placed over each nose-poking hole), two feeder devices, and two food-magazines (each with a magazine light, signalling the length of the timeout, TO) where precision pellets (45 mg, F06555, Bio-Serv, Frenchtown, NJ, USA) were delivered.
The 13th hole at Chambers Bay has the widest fairway in US Open history; Woods missed it.
Sterilized chambers containing the ventricular catheters were built as either "short" or "long" units (Fig. 1) allowing for different positions of the dam relative to the catheter holes (see chamber preparation).
Although the holes and chambers made by those ancient organisms are very similar to those created by today's Osedax worms, "it's very hard to say they were made by the same genus of worms," Martin says.
Bones from the Folsom-age (11,500 11,000 BP) bison kill site in Lipscomb, Texas, contain shallow to deep penetrative holes, ovoid chambers, surface-etched trails, tunnels and channels, and short, U-shaped notches attributed to a variety of insect behaviors.
The cover die contains the sprue (for hot-chamber machines) or shot hole (for cold-chamber machines), which allows the molten metal to flow into the dies; this feature matches up with the injector nozzle on the hot-chamber machines or the shot chamber in the cold-chamber machines.
After treatment with NC, PC, LM100 and LM200 the animals were allowed to cross the hole from one chamber to another and the numbers of passage of a rat through the hole from one chamber to other was counted.
Hot air and gas rushed through the hole when the chamber roof was punctured.
They begin by melting some solid coloured glass in the "glory hole" – the reheating chamber.
These flames cover all typical experimental arrangements, namely stabilizing plate, steel plate with centered hole, and enclosed chamber.
