Abstract: A metal strip is rolled in a roll stand and a control device for the roll stand determines, by means of a working cycle, a number of manipulated variables for flatness actuators of the roll stand and actuates them accordingly. The control device implements an optimizer, which provisionally sets the current correction values, and determines a totality of flatness values. Then, the optimizer minimizes the relationship by varying the current correction variables. When determining the current correction variables (s), the optimizer considers linear ancillary conditions, based at least in part on a vector having the ancillary conditions upheld by the current correction values and a vector having the ancillary conditions upheld by the difference of the current correction values relative to the correction values of the preceding working cycle. The control device determines the manipulated variables for the flatness actuators in consideration of the determined current correction variables.

Abstract: A method for amplification of nucleic acids in which substantially use is made of the fact that a pre-defined nucleic acid chain (target sequence) can be multiplied/amplified in the presence of a target sequence-specific activator oligonucleotide. The target sequence-specific activator oligonucleotide causes the separation of re-synthesized complementary primer extension products by strand displacement, so that a new primer oligonucleotide can attach to the respective template strand. The thus formed complex of a primer oligonucleotide and a template strand can initiate a new primer extension reaction. The thus formed primer extension products in turn function as templates, so that an exponential amplification reaction results. Amplification of a particular target sequence takes place more efficiently in case of perfect match complemetary base pair formation between the activator oligonucleotide and the corresponding target sequence.

Abstract: The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.
