How to kill a query/session without using Teradata Manager

Hi ,
Can you please help me to answer the following.

1.Is there any table or any other source through which I can have details of all the currently running queries in the database belonging to a particular session of a particular user .What I found is the log table “ dbc.QryLog ” ,but this contains the log of all the queries which had already run.
2.I also want to know ,how to kill/abort a query which is running under a session id without using Teradata manager .
