Abstract: An arrangement in a virtual machine for virtual machine supervision is provided. The arrangement comprises a translator operable in the virtual machine. The translator comprises a receiving unit adapted to receive program code to be executed on the virtual machine and a rule referring to the execution of the program code. The arrangement further comprises a code unit adapted to create rule infused machine code based on the program code and the rule, such that the rule is enforced when the machine code is executed on the virtual machine.

Abstract: The present invention relates to a screw implant (1) for insertion into a bore hole (50) arranged in bone tissue, said implant having a cancellous portion (3), and a cortical portion (2) having an axial length such that, when installed in the bore hole (50), the engagement of said cortical portion (2) with the bone tissue will generally be confined to the cortical bone tissue layer (52). Said cortical portion (2) presents an outer surface which is threaded for accomplishing said engagement, and has an outer design such that, when being screwed into said bore hole under action of a screwing torque, said cortical portion (2) acts so as to increase the compression of the cortical bone tissue only, in essentially radial directions of the implant, resulting in a distinct increase of the screwing torque needed for screwing the implant (1). Said increase is usable as an indication that the implant (1) is in place or nearly in place in the bore hole.
