Define the following terms: 1. Horizontal Cable : A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant‚ the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC‚ plenum‚ plenum cable‚ and riser cable. 2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities

Translational motion Translational motion is the aspect in which a body moves from a specific point to the next. This can be in terms of objects‚ molecules or atoms. This kind of motion normally takes place in a straight line for instance bullet which is fired by a gun. The object in motion does not change by turning on its axis for it travels in a straight line. Any slight change or rotation can cause the object to change direction in general making it not move toward the specified direction.

EFFECT OF BREAKWATERS ON WAVE ENERGY DISSIPATION ABSTRACT The northern Egyptian coasts are subjected to many changes in shoreline balance due to waves and coastal currents. To protect and develop these coasts‚ many types of coastal protection structures have been used. This research demonstrates the effect of different systems of coastal protection structures on wave energy dissipation. By using the CGWAVE numerical model‚ the effect of each one and interaction between these structures on

and low velocity pitchers In my paper I plan to explain the difference between a high velocity pitcher and a low velocity pitcher. Confidence‚ resiliency‚ determination‚ leadership‚ integrity‚ composure and location. All of these words are the best qualities of a pitcher. Pitchers are generals on the bump‚ commanders of the field (All terms for a pitcher on the mound). The team is reflected by their pitcher. There are 2 types of pitchers; a high velocity pitcher

BOSTON — Somewhere in Germany is a baby Superman‚ born in Berlin with bulging arm and leg muscles. Not yet 5‚ he can hold seven-pound weights with arms extended‚ something many adults cannot do. He has muscles twice the size of other kids his age and half their body fat. DNA testing showed why: The boy has a genetic mutation that boosts muscle growth. The discovery‚ reported in Thursday’s New England Journal of Medicine‚ represents the first documented human case of such a mutation. Many scientists
