Seismic metamaterial Seismic metamaterial A seismic metamaterial, is a metamaterial that is designed to counteract the adverse effects of seismic waves on artificial structures, which exist on or near the surface of the earth. seismic metamaterials were still in the development stage. More than a million earthquakes are recorded each year, by a worldwide system of earthquake detection stations. The propagation velocity of the seismic waves depends on density and elasticity of the earth materials. In other words, the speeds of the seismic waves vary as they travel through different materials in the earth. The two main components of a seismic event
Therapeutic effect strategy or agent. To maximize therapeutic effects (desired) and minimize side effects (undesired) requires recognition and quantification of the treatment in multiple dimensions. In the specific case of targeted pharmaceutical interventions a combination of therapies is often needed to achieve the desired results. Therapeutic effect Therapeutic effect refers to the responses(s) after a treatment of any kind, the results of which are judged to be useful or favorable. This is true whether the result was expected, unexpected, or even an unintended consequence. An adverse effect (including nocebo) is the converse and refers to harmful or undesired responses(s).
