A method for detecting microorganisms present in a sample comprises the steps of: applying a non-lethal hydrostatic pressure to a sample containing microorganisms; and staining the microorganisms with a fluorescent dye. The method thereof includes determining whether the discrete graphics processing is in an operating state. As the layer is heated, these electronic components are pressed against the layer such that the conductive connecting members of the electronic components become attached to and electrically conductive with corresponding ones of the terminal parts on the circuit board. The conducting wire is connected between the first planar antenna and the second planar antenna. In the Scotch Yoke-type piston motor each cylinder is axially divided by a thermal brake into a thermally insulated outer portion and cooled inner portion.
