    摘要： A method for producing a bonded joint between a light metal of a first component and a steel material of a second component, wherein a protective-gas joining process is used, a zinc-based filler material is used, and wherein an arc of the protective-gas joining process reaches at least the steel material of the second component, wherein a phase space of at least intermetallic phase composed of iron and the light metal is produced in a joining region adjacent to the steel material. Introduction of heat occurs so that the joint to the steel material is a solder or brazed connection and, during joining, a detachment of part of the solidified intermetallic phase(s) from the steel material of the second component starts in a melt of a solder or brazed matrix formed by the filler material and the at least one intermetallic phase is embedded in the solder matrix.

    摘要： A wrist endoprosthesis (2) for functional replacement of the human wrist, containing a radius component (4) that has a shaft (10) for anchoring in the radius, a head (12), and a first joint surface (16), which is implemented on a distal head face (14), and a carpal component (6) that has a proximal carpal face (22), a distal carpal face (20) and a second joint surface (24) which is formed on the proximal carpal face (22) and interacts with the first joint surface (169) of the radius component (4), characterized in that the carpal component (6) is substantially trough-shaped, in order to at least partially surround the carpal bones. Also, a wrist endoprosthesis (2) that has anti-luxation protection (8), a method for producing wrist endoprostheses (2) and a computer program product.

    摘要： The invention relates to a device for performing respiratory training, in particular altitude training, comprising a mouthpiece (1) through which a person can exhale respiratory gas into a volume (2, 3a, 7) or can inhale it out of the volume (2, 3a, 7), wherein this volume (2, 3a, 7) is formed at least in part by a container (2) which is adjustable in terms of its volume and which is connected to the mouthpiece, wherein the volume (2, 3a, 7) adjoins one side of at least one gas-permeable membrane (4), to the other side of which at least one gas exchange chamber (3b) is connected, through which a fluid provided for the gas exchange, in particular CO2 and/or O2 gas exchange, can actively flow. Furthermore, the invention also relates to a method for performing respiratory training, in particular altitude training, wherein a person exhales into a training device through a mouthpiece (1) and inhales from this training device, wherein the O2 and/or CO2 partial pressure in the respiratory gas inhaled from the device is influenced by exchange of O2 and/or CO2 between the respiratory gas in the training device and a fluid provided for the gas exchange through at least one gas-permeable membrane (4).
