... The air just sit there and doesn't get stirred. ... Normally, the air is hottest near the ground and gets cooler as you go up. ... If it weren't for the temperature profile, convection wouldn't occur: Because the temperature decreases with altitude, cold air sits on top of hot air, allowing convection. ... The air above the ground is hot, the air above the water is cold. ... The land cools down faster than the sea, so the air above the ground is colder than the air above the water. ...

. We consider construction of the 2-dimensional tame symbol on a 2-dimensional local field as monodromy of some combinatorial gerbe. From this construction we prove up to sign the Parshin reciprocity laws for these symbols for any algebraic surfaces over any perfect ground field. Go to the Laboratoire Poncelet home page.

XPA supports both inet and unix (local) socket communication. XPA uses sockets for communication between processes. It supports three methods of socket communication: inet, localhost, and unix. ... You can set up a different method by typing something like: setenv XPA_METHOD local # unix csh XPA_METHOD=local; export XPA_METHOD # unix sh, bash, windows/cygwin set XPA_METHOD=localhost # dos/windows The options for XPA_METHOD are: inet , unix (or local ), and localhost . ...
