The present invention is an apparatus for detecting the presence, quantity and identity of one or more microorganisms in a sample and a method for using the same. The ink compositions can produce black recorded images which exhibit excellent fastness and ozone gas fastness. Arranged between the shoulder of the shaft and the roller bearing is a groove which is oriented with a radial directional component and is connected to a hollow space for receiving lubricant, the hollow space being bounded in the radial direction by a ring of the roller bearing and by the shaft. The transmission line can be formed on a first side of a dielectric substrate having a ground plane on a second side of the substrate. The compounds, and compositions containing the compounds, can be used to treat a variety of central nervous system disorders such as schizophrenia. A plurality of second projections are provided on the second die and arranged in the first direction with the fixed pitch.
