The invention relates to a method for the production of 4,4\u2032-methylenebis dimer which is distinguished by an MDI dimer being obtained which is present in high purity. The compressed CO2-based mixture includes carbon dioxide, a surfactant, and water in the form of water-in-CO2 microemulsions. Common scorebooks are generated from the aggregated packet attribute distribution frequencies and nominal traffic profiles, and local cumulative distribution function of the local scores derived from the plurality of security perimeter routers are aggregated. The connector has an elongate shape extending in the longitudinal direction of a connecting shaft, and a first cleaning hole is arranged in an end portion of the connector that is opposite to a side on which the connecting shaft is connected. The first PLL adjusts to the frequency of the transmitter, and provides a bias voltage, CAP1, to the second PLL to indirectly initially tune the second PLL. Contact pressure may be varied by changing the thickness along portions of the projecting ribs or the use of transverse ribs between each of the projecting ribs and a second surface of the end seal.
