Apparatus and a method for assembly of panels into a composite structure are provided. The inner tubular member houses a light-emitting element such as a candle. The quantization step size that generates the highest kurtosis value is selected to the blocks of input-video data during encoding. Each of the legs may have an oil feed hole that traverses from an exterior surface to an interior surface adjacent to the inner sleeve bushing. The respective representative filters act on the respective pixels which form the image, and the results of the action are weighted with the weight vectors and added. The compounds are useful for the treatment andor prophylaxis of diseases which are associated with the modulation of CB1 receptors including obesity.
