Abstract: Data processing apparatus comprises a processing element having an instruction pipeline to execute instructions; and trace circuitry to generate items of trace data indicative of processing activities of the processing element; the trace circuitry being configured to generate items of event trace data in response to events initiated by execution of instructions by the instruction pipeline and to generate items of waypoint trace data in response to instructions, in a set of waypoint instructions, reaching a predetermined stage relative to the instruction pipeline; and the trace circuitry being configured to generate position data, indicating a relative position with respect to execution of the corresponding instructions by the instruction pipeline, of one or more items of event trace data and one or more items of waypoint trace data.

Abstract: The invention relates to processes for separating metals, and in particular for separating precious metals such as platinum and palladium, by solvent extraction. The invention also provides novel solvent extraction mixtures useful in the processes of the invention. The inventors have found that by simultaneously employing different extraction mechanisms for the extraction of a plurality of different metals, a simple and convenient process for their separation can be achieved. In particular, the inventors have found that the use of different extraction mechanisms for simultaneously extracting metals from an aqueous acidic phase into an organic phase enables the extracted metals to be separated by selective stripping from the organic phase using simple and mild conditions. This process is particularly advantageous as it permits two or more metals to be separated following a single solvent extraction step, because of the ability to selectively strip the metals from the organic phase.

Abstract: A method for generating a profile of a target program executed by a target data processing apparatus comprises performing at least one profile updating operation. Each profile updating operation includes identifying based on at least one waypoint marker indicating an outcome of a corresponding waypoint instruction of a target program, a next block of instructions executed by the target data processing apparatus during execution of the target program; determining whether a target entry for the next block of instructions is present in a profile cache; when the target entry is present updating the profile of the target program according to zero, one or more profile updating actions specified by the target entry. When the target entry is absent, any profile updating actions can be determined based on an instruction-by-instruction representation of the target program. This approach helps to speed up instruction-based summaries from program flow trace.

Abstract: A process for the chromatographic interseparation of rhodium in admixture with at least one base metal from a feed solution includes complexes of these metals. The process includes contacting the solution with at least one chromatographic medium, and eluting one or more fractions such that at least one fraction includes rhodium complex substantially free from base metal contamination. The at least one chromatography medium includes a support functionalized with substituted amine groups which further include at least one hydrophilic group. Other platinum group metals can also be separated, both from one another and from base metals.

Abstract: A shelf-stable savory crispy bubbled cheese product and a process for making it is provided wherein cheese pieces containing 50%-60% moisture are tempered followed by vacuum drying in the presence of a heat source followed by freeze drying in the presence of a heat source. The resulting cheese pieces retain or intensify the original cheese color, display no visible oils or chalky powder on the surface, and do not stick tightly or clump together. They are easy to break but not brittle and have a taste comparable to fresh cheese.

Abstract: A chromatographic medium including thioether ligands bound to a cross-linked polymer matrix. The polymer is an organic polymer and the medium is hydrophilic. A method of manufacturing the media is also described. The media are useful in the chromatographic separation of components from solution, and in particular for the interseparation of platinum group metals.

Abstract: A chromatographic separation method separates ruthenium from other platinum group metals in a feed solution, by converting the Ru to a nitrosyl complex, retaining the nitrosyl complex temporarily on the chromatography column and subsequently eluting Ru, for example using an oxidising or reducing eluent. FIG. 1 shows the elution profile obtained from a mixture of Rh chloro-complexes (Peak 1) and Ru nitrosyl species (Peak 2).
