Abstract: The present invention describes a device and a method for grading diamonds using electromagnetic fields with a radiofrequency or terahertz frequency. The method for grading diamonds comprises placing the diamond (4) into a grading device, applying an electromagnetic field with a frequency range of up to 30 THz to the diamond, recording a modulated signal received from the diamond in a form of S-parameters as a function of frequency or any other parameter that can be deduced by applying said electromagnetic field, processing the recorded signal in the processing unit to obtain data containing information about either an amplitude, or phase, or both of the recorded S-parameters as a function of frequency or said any other parameter, performing calculations relating to the obtained data, and running a computer algorithm correlating the calculated data to either nitrogen concentration, boron concentration or plastic deformation in diamonds, thereby allowing grading of the diamond.

Abstract: Securely redirecting a system service routine via a provider service table. A service call provider is loaded within an operating system executing in a lower trust security zone. The service call provider comprises metadata indicating a system service routine to be redirected to the service call provider. Based on the metadata, a provider service table is built within a higher trust security zone. The service table redirects the system service routine to the service call provider. Memory page(s) associated with the provider service table are hardware protected, and a read-only view is exposed to the operating system. The provider service table is associated with a user-mode process. A service call for a particular system service routine is received by the operation system from the user-mode process and, based on the provider service table being associated with the user-mode process, the service call is directed to the service call provider.

Abstract: The present invention describes a method for manufacturing of a composite fixated material comprising the steps of: (a) providing bottom oil shale ash obtained after burning oil shale, said bottom oil shale (BOSA) comprises pozzolanic particles having size of about 10 to 4000 ?m and being capable of adsorbing trace elements at their surface; (b) providing acidic waste comprising said trace elements; and (c) adding the BOSA provided in step (a) to the acidic waste provided in step (b) in amount of about 0.1-0.4 weight parts of said BOSA per one weight part of said waste, and mixing said waste with said BOSA, thereby obtaining a neutralised (scrubbed) precipitate with the fixated trace elements, wherein said neutralised (scrubbed) precipitate with the fixated trace elements constitutes said composite fixated material.

Abstract: The present invention solves the existing problem of using very expensive oxidation reagents, such as H2O2 and ozone, in removal of NOx and SOx from flue gases, by performing simultaneous oxidation of NOx and SOx with atmospheric oxygen in a combined system for catalytic oxidation and wet-scrubbing of both NOx and SOx from a flue gas and manufacturing fertilisers. Two major configurations of the oxidation system are disclosed in the present invention. The first configuration operates on oxygen-enriched air to increase efficiency of the oxidation reaction and requires an additional oxygen concentrator unit. The second configuration operates on atmospheric air at ambient conditions and requires an additional catalyst activation unit. In the second configuration, the efficient oxidation process is carried out at low temperatures of about 30-90° C. in the presence of recovered and re-activated catalyst.
