It suppresses ignition noises from sparks. Resistor spark plugs prevent electrical interference that can disrupt car radio reception, two-way radio and cellular phone operation. This type of spark plug also prevents electrical noise from interfering with the operation of the computer in the engine. 1  Noise suppression effects of a resistor spark plug. (Compared with one of our conventional types) 2  As shown above, noise is reduced in all frequency zones by installing resistor spark plugs.
This is the first time we have taken a comprehensive view of mental illness on its own.. Estimates of mental illness -- such as major depressive disorder and other mental health problems -- were made based on data from the 2009 National Survey on Drug Use and Health, which polls about 68,700 Americans ages 12 and up.
1 Mental illnesses are very common; in fact, they are more common than cancer, diabetes or heart disease. 2  According to the U.S. Surgeon General, an estimated 23% of American adults (those ages 18 and older) or about 44 million people, and about 20% of American children suffer from a mental disorder during a given year. Even though mental disorders are widespread in the population, the main burden of illness is concentrated in a much smaller proportion â about 6 percent, or 1 in 17 Americans â who suffer from a serious mental illness. 2  It is estimated that mental illness affects 1 in 4 families in America.
