Methods and compositions for treating humans suffering from, or preventing a human from suffering, a physiological or psychiatric disease, disorder, or a condition where inhibiting reuptake of norepinephrine is a benefit are disclosed. The image processing apparatus and method for enhancing the depth perception may classify an input image including a plurality of layers according to a depth into a foreground layer, a middle layer, and a background layer, and process a color component of each of the layers. A filter is applied in each frame to attenuate frequencies above or below the narrowband signal, and an inverse Fourier transform is applied to produce an output signal. The headphone or earphone also includes an electro-acoustical transducer inside the housing for reproducing the compensation signal. The present invention forms a low-k organic polymer dielectric layer or an organic-doped oxide dielectric layer having improved nucleation andor adhesion properties for a subsequently deposited layer such as a barrier material layer. The blocker insert can be formed with a cooling air passage therein in order to provide additional cooling for the finished airfoil.
