Balls are open sets under the topology induced by the metric, and therefore are examples of neighborhoods.
A ball is sometimes referred to as a disc, although disc is usually reserved for a ball in a metric space having the structure of a two-dimensional vector space.
Ball and Ball produces antique reproduction hardware of the highest quality.
Ball and Ball antique reproduction builder's hardware, is accurate in every detail to original hardware, making it unique among most builders' hardware available today.
Ball and Ball can expertly reproduce many of these items using the same methods and techniques that were used in the making of the originals.
The closing apparatus of the ball valves in these patents are arranged such that the return spring force and the pressure of the compressed gas is at its lowest point during the last increment of travel of the ball operating mechanism rotating the ball to the fully closed position.
A ballclosing piston is disclosed wherein one side is exposed to the pressure in the drill stem below the ball valve, and a second side is exposed to pressure which exists in the tester valve apparatus having a lower value due to the mentioned throttling effect.
As the ball valve is moved further toward the closed position, the orifice between the ball valve seat and the ball valve is made smaller and smaller thus increasing any pressure drop due to the fluid flowing between the ball valve and the ball valve seat.

Electrodynamic Explanation of Ball Lightning(Site not responding. Last check: 2007-11-03)
Ball lightning is considered as self-closed alternating displacement current, which produces air luminescence (electroluminescence).
Ball lightning is the visible proof of the fact that displacement currents exist in nature along with conduction currents.
Ball lightning has energy and is a rather stable field form of matter.
Ball valves are the most commonly used kind of valve for controlling propellant flow and feed pressure to the propellant tanks.
Between the ports is a channel containing a sphere (the "ball") with a hole through its center and suspended by seating material that holds the ball in place and seals the volume outside the ball from fluid flow around it.
The diameter of the ball channel is the specified diameter of the ball valve.
A closed clubface is the primary cause of a hook and I find this is often the result of the player's effort to keep it square, or facing the target, during the back swing.
The ball flight you describe is the result of the club face at impact being severely closed relative the the club path.
The reason your ball barely gets airborne, is because your clubface position at impact is extremely closed which is not allowing the effective loft of the club to work at all.
for example although the closure of the open ball of radius one about p is not the closedball of radius one, it is the closedball of radius 1/2.
Because the closedball of radius 2 includes 2, and the closure of this open ball does not, this closure is not the closedball of radius 2.
The original post had 'not a closedball' rather than 'not a closedball of the same radius', and I thought you were referring to that with the comment about closedballs of a different radius.
Mystery Tank Responses(Site not responding. Last check: 2007-11-03)
Only thing is this one stuck in the closed position (it happens!) and the new driver didn't relieve the pressure by opening the drain on the spill containment manway (unless this was a drain-less version).
Tank ullage spaces were connected via the vapor manifold but since the 87 grade ball float on the dual point vapor riser was also closed, vapors returning to the 87 grade tank could not enter this crossover manifold and pass to the 89 or 92 grade tanks other than through the.062 diameter bleed hole.
The dual point riser ball float is oriented as such that it does act as a check valve for vapors passing from the 87 tank to the 89 and 92 tanks or the vent stacks.
Series SW signals the open or closed valve position for computer verification or to actuate other equipment based on the valve position.
The open position of the True Blue ball valve is adjustable for throttling by using the optional Series LS Limit Stop.
Series MBV -- True Blue Ball Valves -- Manual version of Plast-O-Matic's popular ball valve line; constructed with integral mounting lugs for easy addition of an actuator when needed.
True, Queen Fuzzy lives a pampered life, but is not one to squander her good fortune selfishly and has therefore decreed that a Fuzzy Ball be held for the fun and entertainment of those how would wish to visit the Fuzzy Forest.
Mary Starlight is pleased to be involved in the ball.
Lady Sarinja was excited at being invited to the ball, but her quiet unassuming nature only served to make guests wonder what she was really up to.

Since the disjoint open intervals of boundary(B) are >closed sets in the topology of Y', their inverse images in E^2 are >closed sets, which are in different path components from each other, >and different connected components.
Since the two definitions agree on a closed set, g is continuous.
