A mechanism for continually testing a first processor element in a suitable multiprocessor system in which at least first and second processor elements are connected to a common input bus to concurrently receive the same opcodes and operands. Both processors decode the opcodes; when an opcode indicates an operation to be performed by the second processor, the first processor responds by executing ...

The invention relates to concrete and mortar for the wet-spraying process, whose setting time is extended and, for example, retarded to such an extent that it can be supplied from a ready-mixed concrete works to the building site and remains processable at the latter for up to 2 days, but can be caused at any time to stiffen immediately, to set and to harden quickly by addition of a setting accele...

Healing of injured avascular tissue is promoted by applying angiogenic factor in proximity to the injured tissue in the form of an implant.

The use of dsRNA for the mfr. of a medicament to treat a dsRNA-deficient disease state, excluding HIV infection or cancer, is claimed. Also claimed is a method for diagnosing a dsRNA deficient disease state comprising assaying a sample from a patient for dsRNA and comparing results with a normal control. More specifically, the dsRNA is mismatched and has formula r1n.r(C11-14(n. The dsRNA deficienc...
