the set of every set is that set
'Mull Set' . I think you mean 'NULL SET'. This means a set with no elements, or an empty set.
The set contained in another set is termed as a sub-set.
A null set is a set that does not contain any elements, an empty set.
A null set is a set with nothing in it. A set containing a null set is still containing a "null set". Therefore it is right to say that the null set is not the same as a set containing only the null set.
Erm.. a couple of hours.
Mortise and tenons are used by woodworkers to join pieces of wood. the basic mortise and tenon comprises two components: the mortise hole and the tenon tongue.
A Mortise is usually a piece cut out and the insert is called a tenon...these two pieces make a joint.
The partner of a mortise is a tenon. A mortise is a cavity or hole cut into a piece of wood or other material, while a tenon is a projecting piece of wood or other materials that is designed to fit into the mortise, creating a joint. Together, a mortise and tenon form a strong and stable connection in woodworking.

A Mortise Lock is unique in that when it is fitted by a locksmith, a small section - Mortise is cut through the door frame to connect the lock. The lock is different to others in that a homeowner cannot fit it as one requires wood making knowledge and tools and it is labour intensive.
A mortise Lock is most commonly used on doors. It requires a "pocket" or hole to be cut in the door, and a plate to be places in the frame that the door will attach to when closed.
A Mortise Cylinder (also mortice lock in English) is one that requires a pocket-the mortise-to be cut into the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise locks are generally found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States. They are widely used on all ages of domestic properties in Europe.
