Abstract: Exemplary sanitary soap refilling systems and methods are disclosed herein. An exemplary refill refilling system includes a housing, a pump located within the housing, and a bulk storage tank connector. The bulk storage tank connector having a liquid outlet and an air inlet. A liquid inlet conduit is in fluid communication with the pump the liquid outlet. A refill connector is included. The refill connector has a liquid inlet and an air outlet. The refill connector air outlet and the bulk storage tank connector air inlet are in fluid communication with one another. The refill liquid inlet is in fluid communication with the pump.

Abstract: In one example, a system can receive an order from a client device. The system can also receive data about a set of print queues at a set of printers via a network. The system can then determine a set of queue times corresponding to the set of print queues. Each respective queue time can be determined based on a corresponding print queue. The system can generate an estimated wait time for the order based on the set of queue times. The system can then transmit the estimated wait time to the client device for display in a graphical user interface to a user associated with the order.

Abstract: A microfluidic electrochemical device and process are detailed that provide chemical imaging and electrochemical analysis under vacuum at the surface of the electrode-sample or electrode-liquid interface in-situ. The electrochemical device allows investigation of various surface layers including diffuse layers at selected depths populated with, e.g., adsorbed molecules in which chemical transformation in electrolyte solutions occurs.

Abstract: The invention provides mutant pyrogenic toxins. Preferred mutants retain a disulfide loop structure, although the endogenous sequence of the disulfide loop may be modified for example by insertion, deletion and/or substitution of at least one amino acid residue, or by combining a pyrogenic enterotoxin (or a fragment thereof) with another polypeptide to provide a chimeric molecule. Preferred mutants have a disulfide loop having less than about 8 amino acid residues. The invention also provides a system for producing the mutant pyrogenic toxins and methods of use for the mutants.
