Gerbner writes that this provides a double dose of messages that resonate and amplify cultivation. Detector and power rectifiers could not amplify a signal. Repeaters amplify the signal periodically along the line. Self-reinforcing feedbacks amplify and accelerate climate change. You make primers specific to the site you want to amplify. This "active amplifier" is essential in the ear's ability to amplify weak sounds. This is done to amplify the signal. In addition, certain genetic factors can amplify the negative effects of acetaldehyde. Gold nanoparticle could also amplify the SPR signal. Horns having an exponential profile amplify the sound. The column may be inclined to further amplify the liquid movement. They possess air pouches connected to the pharynx which may amplify their vocalizations. Taq polymerase can however amplify targets of up to several thousand bp long. Therefore, it will amplify both methylated and unmethylated sequences, in contrast to methylation-specific PCR. Some herbs may amplify the effects of anticoagulants.
