An article for controlling flow of a fluid medium in a fluid path comprises a brush seal carrier and at least one brush seal coil disposed within the brush seal carrier. The insulated metal substrate includes a dielectric layer positioned between first and second metal layers, and a plurality of stress-relief through-features extending through the first metal layer, the second metal layer, the dielectric layer, or combinations thereof. The invention furthermore relates to a brush with and for a bristle holder of the described type. The position adjusting mechanism adjusts the position of the slide and is provided below the adjustor member. Also, the user can add annotations to the search query prior to its being forwarded to the hub processing unit. A second inter-layer insulating layer is formed on the substrate and then a conductive plug having contact with the drain region is formed in the second inter-layer insulating layer and the first inter-layer insulating layer.
