Abstract: An architecture for resource management in a telecommunications network includes two or more nodes connected over a logically direct path in a peer-to-peer manner. At each node, local events typically trigger the node to transmit a broadcast to every other node. Broadcast information comprises a status of the local node's resources. Remote nodes receive the local node's broadcast and independently transmit their own broadcasts with similar information. Each node stores the received broadcast information in a local storage for future retrieval. When a session is desired with a remote node, the local node simply retrieves the remote node's resource status information from its local storage and determines if a session can occur. In this manner, every node of the network is aware of the nodal addresses of the other nodes, remote node's resource status, and can quickly retrieve, from its own local storage, the availability of the remote node's resources.

Abstract: The invention provides a method for measuring an acyl coenzyme A (acyl CoA) ester or esters in a sample, comprising the steps of: a) forming a reaction mixture comprising the sample to be tested and a derivatizing agent; b) allowing the sample and said derivatizing agent to react, so as to form a fluorescent derivative(s) of any acyl CoA ester(s) present in the sample; and c) determining a level of said fluorescent derivative(s).

Abstract: A downhole apparatus permitting separation of one part of downhole equipment from another part thereof includes a first part (4) connected to a second part (6) by connecting means which limits axial and rotational movement between the parts. The connecting means includes a connecting member (22) having first and second ends connected respectively to the first and second parts (4, 6). The connection of the first and second ends of the connecting member (22) is such as to limit axial and rotational movement relative to the respective first and second parts (4, 6).

Abstract: The present invention relates to downhole apparatus and particularly but not exclusively, to multi-cycle circulating subs used during downhole drilling operations. Apparatus is provided comprising a piston (42) slidably mounted in a body (4) between positions in which at least one aperture (40) in the body is opened and closed. Movement of the piston (42) is controlled by a pin (86) secured to one of the body and a control member, and a control groove (52) in which a portion of the pin is received formed in the other of the body and control member. An arrangement of elements (32, 76) respectively connected to the control member and body is such that, as the control member moves axially, increasing lengths of said elements locate adjacent one another so as to provide resistance to relative rotation in at least one direction of the control member and body. The relative rotation is rotation which presses the control member against the control groove.
