The expression dBm is used to define signal strength in wires and cables at RF and AF frequencies. The symbol is an abbreviation for decibels relative to one milliwatt, where one milliwatt (1 mW) equals 1/1000 of a watt (0.001 W or 10 -3 W). This unit is commonly used in test laboratories. The dBm increment is based on the decibel , a logarithm ic measure of relative power . Suppose a signal has a power level of P mW. Then the signal strength in dBm, symbolized S dBm , is: S dBm = 10 log 10 P. A 1-mW signal has a level of 0 dBm.
These 10 animal facts will amaze you. Decortication is a term which is used to refer to the removal of a rind or peel. In a medical context, the term means removing the fibrous outer layer of tissue which covers an organ.

Decora Imperial or Balcon Red is one of the most widely grown geraniums in the UK and Europe-if you've seen a chalet or villa with bright red geraniums tumbling down from window boxes, chances are it's this one!ot up pelargonium plants and grow them on in warm frost-free conditions. When all risk of frost has passed, gradually acclimatise geraniums to outdoor conditions over a period of 7 to 10 days before transplanting them into their final positions in containers, baskets or window boxes.
