Abstract: Methods, systems, and computer programs are presented for estimating downtime and recovery time after a disaster. One method includes an operation for calculating component fragility functions for components of a facility that are vulnerable to damage after a disaster. Further, the method includes calculating component recovery functions for the components of the facility. The component recovery functions indicate a probability of recovery after a disaster over time. The method further includes operations for calculating a facility fragility function and a facility recovery function based on the component fragility functions and the component recovery functions, and for determining a downtime for the facility for a given intensity associated with the disaster. Further, the method includes an operation for causing presentation of the downtime for the facility on a user interface (UI).

Abstract: The present invention discloses a membrane-less reactor design for microbial electrosynthesis of alcohols from carbon dioxide (CO2). The membrane-less reactor design thus facilitates higher and efficient CO2 transformation to alcohols via single pot microbial electrosynthesis. The reactor design operates efficiently avoiding oxygen contact at working electrode without using membrane, in turn there is an increase in CO2 solubility and its bioavailability for subsequent CO2 conversion to alcohols at faster rate. The present invention further provides a process of operation of the reactor for biotransformation of the carbon dioxide.

Abstract: A mesh-shaped, porous electric current density distributor is for use with an electrode, and is adapted for providing electric current to an active layer of the electrode. The active layer contacts a face of the current density distributor, and the current density distributor includes a porous mesh having several electrically conductive paths. At least part of the electrically conductive paths extend along a direction of major current flow over the current density distributor. The porous mesh includes in a direction crosswise to the direction of major electric current flow, several paths of an electric insulator. The current carrying capacity of the current density distributor in crosswise direction to the major current flow over the current density distributor is smaller than the current carrying capacity in the direction along the major current flow over the current density distributor.
