Abstract: A method for cleaning of a roller screen transporting and screening particles by means of at least three rotating rollers. The rollers are installed in succession at given clearances and arranged transversally in relation to the transport direction of the particles to screen a desired range of particle sizes. At least one roller changes its circumferential velocity and/or its rotational direction over time at defined time intervals for defined time periods such that for this defined time period for at least one pair of neighbored rollers one roller has a higher circumferential velocity than the other and/or both rollers roll in opposite rotational directions.

Abstract: A method and its related plant for the thermal treatment of iron containing oxide, in which fine-grained solids are heated in a preheating calcining stage and exposed to a reduction gas in a subsequent reduction stage. Off-gas from the reduction stage is guided through a separation device wherein water originating from the reduction stage is separated. The water separated in the separation device is recycled into a water treatment section, from which the recycled water is supplied to a water electrolysis plant and/or a steam reforming plant producing hydrogen, and the produced hydrogen is supplied to the reduction stage as reductant and/or to the preheating calcining stage as fuel and/or to the gas heater as fuel and/or from which the recycled water is supplied to the separation device.

Abstract: Provided are processes for the prevention or treatment of viral infection in a subject. Some aspects provide administration of a sphingoid compound, optionally sphingosine, an active ingredient that activates generation of a sphingoid base, optionally of sphingosine; or an active agent that inhibits the degradation of a sphingoid base, optionally of sphingosine, to a subject such as a human. By increasing the local concentration of sphingosine in a subject or an area of a subject to which the composition is administered such as the nose or interior of the nose or portion thereof, the ability of viruses to infect the subject or cells thereof is reduced thereby treating of preventing infection by the virus.
