Abstract: A kit for subsequent injection and/or subsequent insertion of at least one medical substance in the fluid or liquid state and/or of at least one element in a human body injection or insertion site. The kit includes a first syringe element and at least one second syringe element. The first syringe element includes an internally hollow cylindrical body, a plunger and a first needle. The plunger is suitable to slide inside the cylindrical body in use. The at least one second syringe element includes a piston and a second needle. The at least one medical substance is inserted into the cylindrical body and the first syringe element is suitable to house, at least partially therein, the at least one second syringe element or the second needle is suitable to pass through the plunger in use.

Abstract: A method and apparatus for efficiently constructing a bounding volume hierarchy (BVH). For example, one embodiment of an apparatus comprises: a primitive sampler to identify a representative subset of input primitives of a graphics scene; bounding volume hierarchy (BVH) builder hardware logic to construct an approximate BVH based on the representative subset of input primitives; hardware logic to insert input primitives not in the representative subset into leaves of the approximate BVH; and the BVH builder or a different BVH builder to construct a final BVH based on the primitives inserted into the leaves of the approximate BVH.

Abstract: Apparatus and method for generating a quasi-random sequence. For example, one embodiment of an apparatus comprises: a graphics processor comprising execution resources to execute graphics instructions; and quasi-random sequence generation logic implemented, at least in part, in program code executed by an execution unit, the quasi-random sequence generation logic to generate a Sobol number sequence to be used by the graphics processor for rendering operations, the Sobol sequence generator to perform the operations of: generating white noise bits; mixing the white noise bits with Sobol bits to generate a quasi-random result sequence.

Abstract: The present invention relates to a mixture of sterile and apyrogenic gases based on CO2 and O2 suitable for producing microbubbles which can be used in the medical, phlebological and diagnostic field. The gas mix allows stable and physiologically acceptable microbubbles to be formed, by means of more standardized procedures which are easy to effect.

Abstract: A method of producing injectable foam, comprises: providing a first syringe containing a gas and a second syringe containing a liquid comprising a foaming substance and passing the gas and the liquid back and forth between the first syringe and the second syringe by operation of the first syringe and the second syringe so that the gas and the liquid mix turbulently to form the foam.
