The presence of a pathologic process in a lung of a mammal is detected by applying exhaled gas of a mammal to an electronic nose. The present invention also relates to a garment produced by means of a yarn of this type and to a method for production of the yarn itself. Next, the system can receive empirical data which is obtained using a process that includes subjecting the test layout to one or more semiconductor manufacturing processes. An opening is then formed to expose a surface of the doping area. The head portion consists of a first part, which extends from a first side of a plane including the longitudinal axis, and a second part, which extends from the other side of said plane and which is larger than the first part.
