Methods and apparatus for resolving false dependencies associated with speculatively executing load instructions in a processor core are described. The method for reforming the used raw material is either a method for contacting the used raw material with a hydrogenation catalyst or a reducing agent or a method for contacting the used raw material with either a halogen, a hydrogen halide, an inorganic acid, an alkene, or a diene. The connecting arrangement includes a securing element designed as a sliding latch arranged on the wiper arm. The gastrointestinal device includes an anchor for anchoring the device to the stomach and a flexible sleeve to limit absorption of nutrients in the duodenum. The stator chip includes a first planar substrate having a contact face and a second planar substrate having a contact face bonded to the contact face of the first planar substrate.
