Abstract: A communication system comprising a server and a plurality of clients constrained so that in order to communicate with each other by means of the system they must communicate via the server, the server having access to a set of stored communication rules defining permitted and/or non-permitted communications between the clients and the server being configured to, on receiving a message from a first client designating as recipients a second client and a third client, the first client matching a first set of characteristics stored in the communication rules and the second client and the third client being clients who are not permitted to directly communicate according to the communication rules, alter the communication rules to permit the second and third clients to directly communicate.

Abstract: A process for co-depositing tailings streams and/or tailings products is provided comprising providing a tailings containment structure; and co-depositing at least two different tailings streams and/or tailings products into the tailings containment structure.

Abstract: A computer-implemented method and a system for managing signals generated by onboard systems of a mobile equipment fleet, where each of the signals contain operating condition information associated with one of the items of the fleet. The system continuously receives the signals as transmitted by the onboard systems via a communications network. For each of the received signals, the system selects a rule from a rules database based on the equipment operating condition information in the received signal. The rule contains a cause and an action associated with an equipment operating condition. The system generates a report that includes the equipment operating condition, the cause and the action of the selected rule and transmits it to an operator device via the communications network.

Abstract: A process for containing tailings produced during an oil sands operation includes filling and containing the tailings in a geotextile container.

Abstract: A detection system comprising modulation means for applying a circular polarisation modulation to an incident beam of radiation, sample holding means through which the modulated beam is passed, a grating to diffract the beam of radiation, an array of solid state detectors arranged to receive different wavelengths of the beam, and processing means arranged to synchronise detected signals with the modulation applied by the modulation means, in order to measure the spectral circular dichroism of the sample.
