An apparatus for holding an object has a holding piece for holding the object. The PAO comprises oligomers of one or more C2 to C20 alpha-olefins having a kinematic viscosity at 100\xb0 C. The output provides a RESET signal to clear all volatile memory in the chip in the event of the power supply voltage exceeding the predetermined limits. A threshold level is detected for each one of the memory cells of the first group only. 1 mgmL or less,processes for preparing them, and their use in the treatment of respiratory complaints, asthma, and chronic obstructive pulmonary disease.
