Submarine cables Laying of cables in the oceans of our world is a fascinating business. Real men and women toil long and tedious hours to make this possible. Submarine cables are laid down by using specially modified ships (sometimes even purpose built ships) that carry the submarine cable on board and slowly lay it out on the seabed as per the charts/plans given by the cable operator. The ships can carry with them up to 2‚000 kilometers length of cable. Depending on the equipment on-board

Introduction Coaxial cable: is an electrical cable consisting of a round conducting wire‚ surrounded by an insulating spacer‚ surrounded by a cylindrical conducting sheath‚ usually surrounded by a final insulating layer. It is used as a high-frequency transmission line to carry a high-frequency or broadband signal. Sometimes DC power (called bias) is added to the signal to supply the equipment at the other end‚ as in direct broadcast satellite receivers. Because the electromagnetic field carrying

CULINARY CALCULATIONS The Standardized Recipe The standardized recipe is the hallmark of the foodservice industry today. The information contained in the standardized recipe ensures that a consistent product is always served to the guest. A consistent product means the look‚ taste‚ texture‚ and portion size of the menu item is the same each time the item is prepared and served‚ regardless of who is in the kitchen on a given day. Each standardized recipe has a specific yield‚ which can be increased
