Resonator The guitar resonator is a device for driving guitar string harmonics by an electromagnetic field. This resonance effect is caused by a feedback loop and is applied to drive the fundamental tones, octaves, 5th, 3rd to an infinite sustain. Resonator A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from
Conceptual metaphor conceptual metaphor to how learners learn and what teachers do in the classroom. A current study showed a natural tendency to systematically map an abstract dimension, such as social status, in our closest and non-linguistic relatives, the chimpanzees. In detail, discrimination performances between familiar conspecific faces were systematically modulated by the spatial location and the social status of the presented individuals, leading to discrimination facilitation or deterioration. High-ranked individuals presented at spatially higher position and low-ranked individuals presented at lower position led to discrimination facilitation, while high-ranked individuals at lower positions and low-ranked individuals at higher position led to discrimination
