Abstract:
The invention relates to a vibration dosimeter (2) and a method for determining the daily vibrational loading of persons who are exposed to mechanical oscillations at their place of work due to the operation of a work means and in particular of a manually operated electronic tool (4, 6). What is provided is that the dosimeter (2) comprises a determination device (12, 18) for determining the effective daily operating duration of the work means (4, 6), a computer device (22) for calculating a daily work time until a specified trigger value or exposition limit value of the vibrational loading is reached from a work-means-typical vibration value and the trigger value or exposition limit value, and a comparison device (24) for comparing the determined effective daily operating duration of the work means with the calculated daily work time until the specified trigger value is reached.

Abstract:
The present invention relates generally to a method of modulating tumor necrosis factor-mediated apoptosis and to agents useful for same. More particularly, the present invention contemplates a method of modulating tumor necrosis factor-mediated hepatocyte apoptosis by modulating an intracellular Bim and/or Bid-dependent signalling mechanism. The method of the present invention is useful, inter alia, in the treatment and/or prophylaxis of conditions characterized by aberrant, unwanted or otherwise inappropriate tumor necrosis factor-mediated apoptosis. The present invention is further directed to methods for identifying and/or designing agents capable of modulating the subject Bim and/or Bid-dependent signalling mechanism.
Abstract:
In a method of processing a contact pad, a passivation layer stack including at least one passivation layer is formed on at least an upper surface of a contact pad region. A first portion of the passivation layer stack is removed from above the contact pad region, wherein a second portion of the passivation layer remains on the contact pad region and covers the contact pad region. An adhesion layer is formed on the passivation layer stack. The adhesion layer is patterned, wherein the adhesion layer is removed from above the contact pad region. Furthermore, the second portion of the passivation layer stack is removed.
Abstract:
The invention relates to a machine tool comprising an electric motor (2) which serves to drive a tool and which has an adjustable, electric brush arrangement (3), and comprising a mode selector switch (6) having various switch positions. Provision is made for an adjusting device (8) to displace the brush arrangement (3) as a function of the switch position of the mode selector switch (6). Furthermore, the invention relates to a corresponding method.
