Abstract: The present invention refers to a process of obtaining ?-glucan from yeast cells, which involves the initial growth of the yeast, the autolysis of said cells to obtain yeast cell walls, the alkaline treatment of these with sodium hydroxide comprising retention periods, the acid treatment of the insoluble product obtained, and the collection and handling thereof to obtain a powder product enriched in ?-glucan with a fat percentage of less than 4%.

Abstract: A payment processing system, components thereof and associated methods are provided which may prevent fraud associated with financial transactions.

Abstract: A measurement instrument includes selectable channels for simultaneously measuring current on a power rail/load of a device under test. Multiplexor circuitry can be controlled to select power rails/loads for measurement and to couple unselected power rails to bypass the measurement circuitry. Active loads are provided in the measurement circuitry to compensate for loading by the measurement circuitry. The active loads cause current on a source side of a selected power rail/load to match current measured on a load side of the selected power rail/load during power measurements.
