Abstract: A fluid extraction system for a lithographic apparatus, the fluid extraction system configured to extract fluid that a fluid handling system, including a fluid handling structure, is arranged to supply along a flow path that includes a gap between an edge of a substrate and an edge of a surrounding structure of the substrate; and a controller arranged to control the flow rate of the fluid in the flow path in dependence on one or more selected from: a property of the substrate, a property of the fluid handling system, a property of the fluid handling structure, a property of the fluid extraction system, and/or the separation between the fluid handling structure and the fluid extraction system.

In particular the use of myramistin, its derivatives and forms for treating or ameliorating infections caused by coronaviruses. More particularly, the present description relates to the use of myramistin, its derivatives and forms thereof for treating or ameliorating Coronavirus disease 2019 (COVID-19).

Abstract: System and methods for controlling and optimizing coolant system parameters in a fuel cell system to obtain a requested cabin temperature in a fuel cell vehicle are presented. A method for managing a temperature in a vehicle cabin may include receiving an indication relating to a desired vehicle cabin temperature and a plurality of measured operating parameters. Based on the measured operating parameters, a projected output temperature of a cabin heat exchanger may be estimated. A determination may be made that the projected output temperature of the cabin heat exchanger is less than the indication. Based on the determination a fuel cell coolant parameter may be adjusted.

Abstract: A system for conditioning the air in a passenger compartment of a fuel cell-powered vehicle is provided, the system including a metal hydride buffer and a hydrogen source, wherein the metal hydride buffer reversibly adsorbs and desorbs hydrogen gas. The change in temperature associated with adsorption or desorption of the hydrogen gas by the metal hydride buffer is thermally communicated to the passenger compartment, thereby conditioning the air therein. Desorbed hydrogen gas is fed back to the fuel cell to power the vehicle. Also provided are a vehicle having a system for conditioning air in a passenger compartment that employs the change in temperature resulting from the adsorption and desorption of hydrogen gas by the metal hydride buffer and methods for heating or cooling a passenger compartment of a fuel cell-powered vehicle.
