Abstract: Systems and methods for mutual authentication of a user and a container administrator computer system. A container administrator computer system receives a request from a mobile computing device for a user to access a secure container. The request includes a user identifier. The administrator system receives a first authentication factor corresponding to the user. The administrator system authenticates the user by verifying that the first authentication factor matches a first reference authentication factor associated with the user identifier. The administrator system sends a second authentication factor associated with the administrator system to a human-machine interface associated with the secure container or the mobile computing device. The administrator system receives a notification of authentication of the administrator system using the authentication factor. The administrator system transmits an unlock signal to unlock the secure container.

Abstract: An apparatus for measuring a characteristic of a sample using a centrifuge and optical components is disclosed. The centrifuge may be a standard benchtop centrifuge. The optical components may be sized and dimensioned to fit, along with the sample, inside the centrifuge.

Abstract: Embodiments enable a user to input voice commands for a system to read text, augment text with comments or formatting changes, or adjust the reading position. The user provides a command to read the text and a start position is determined. The audio reading of the text at that position is output to the user. As the user is listening to the reading of the text, the user provides additional voice commands to interact with the text. For example, the user provides commands to provide comments, and the system records the comments provided by the user and associates them with the current reading position in the text. The user provides other commands to format the text, and the system modifies format characteristics of the text. The user provides yet other commands to modify the current reading position in the text, and the system adjusts the current reading position accordingly.

Abstract: A process for producing formaldehyde-stabilised urea is described comprising generating a synthesis gas, subjecting the synthesis gas to water-gas shift to form a shifted gas; recovering carbon dioxide from the shifted gas; synthesising methanol from the carbon dioxide-depleted synthesis gas; subjecting recovered methanol to oxidation; subjecting the methanol synthesis off-gas to methanation; synthesising ammonia from the ammonia synthesis gas and recovering the ammonia; reacting ammonia and recovered carbon dioxide stream to form a urea stream; and stabilising the urea by mixing the urea stream and a stabiliser prepared using the recovered formaldehyde, wherein a portion of the synthesis gas by-passes either the one or more of the water-gas shift reactors, carbon dioxide removal unit, or water-gas shift reactors and the carbon dioxide removal unit used in the process.

Abstract: A process for the production of formaldehyde-stabilised urea is described comprising the steps of: (a) generating a synthesis gas comprising hydrogen, nitrogen, carbon monoxide, carbon dioxide and steam in a synthesis gas generation unit, (b) subjecting the synthesis gas to one or more stages of water-gas shift in one or more water-gas shift reactors to form a shifted gas; (c) recovering carbon dioxide from the shifted gas in a carbon dioxide removal unit to form a carbon dioxide-depleted synthesis gas; (d) synthesising methanol from the carbon dioxide-depleted synthesis gas in a methanol synthesis unit and recovering the methanol and a methanol synthesis off-gas comprising nitrogen, hydrogen and residual carbon monoxide; (e) subjecting at least a portion of the recovered methanol to oxidation with air in a formaldehyde production unit; (f) subjecting the methanol synthesis off-gas to methanation in a methanation reactor containing a methanation catalyst to form an ammonia synthesis gas; (g) synthesising ammo
