A method for treating attention deficithyperactivity disorder includes performing an objective ADHD behavioral assay for a patient, administering a drug to the patient at varying doses, and performing an fMRI on the patient for the varying drug doses to determine an optimal dosage for the patient. In the motor, a stator core includes a main core and a sub-core. According to the invention, electric fields can be utilized to selectively inactivate and render non-viable particular subpopulations of cells in a suspension, while not adversely affecting other desired subpopulations. A lid plate covers the opening completely, and the interposed foil conductor strip is thus connected in an oil-tight manner with the housing lid. The second sidewall is moved to the closed position for contained transport of recyclable materials over public roads.
