Abstract: Illustrative embodiments of systems and methods for detecting and responding to islanding of distributed energy resources are disclosed. In at least one illustrative embodiment, a method may include measuring voltage and current at a connection point between a distributed energy resource and an electrical grid, determining a Thévenin impedance of the electrical grid based upon the voltage and current measurements, and determining whether the Thévenin impedance has exceeded a predetermined threshold. In some embodiments, the method may further include disconnecting the distributed energy resource from the electrical grid in response to determining that the Thévenin impedance has exceeded the predetermined threshold.

Abstract: The presently disclosed subject matter provides a free-energy based model of translation elongation to predict and optimize heterologous gene expression. The model and software allow for the prediction and optimization of genes for increased or decreased protein yield and for increased or decreased protein aggregation.

Abstract: A wash separator comprises a vessel containing a first fluid and a second fluid whereby the second fluid has a different density from the first fluid. The first fluid (3) is immiscible with the second fluid and the first and second fluids are separated from each other by an interface. A feed stream comprising a dispersion of the first and second fluid wherein the second fluid forms a disperse phase in the form of droplets is distributed within the first fluid in the vessel forming a continuous phase. A distribution element is provided in the vessel to distribute the feed stream into the second fluid. The feed stream after having been discharged from ,the distribution element has a retention time of at most 15 minutes in the feed second fluid in the vessel.
