Abstract: A process for producing a flexographic relief printing plate includes using a photopolymer developing solution. This photopolymer developing solution may comprise butylal alone or butylal and one or more organic cosolvents. It may comprise DPnB and one or more cosolvents and no butylal.

Abstract: An in vitro or ex vivo method for determining the ability of an individual to respond to a stimulus, based on the measurement of the expression of at least two different biomarkers, selected from different lists among three lists of biomarkers, from a blood sample of the individual, incubated with the stimulus, as well as tools allowing the implementation of this method and the use of these tools.

Abstract: It is proposed to provide a photopolymer developing solution for providing a flexographic relief printing plate. This photopolymer developing solution comprises butylal alone or butylal and one or more organic cosolvents that are liquid at room temperature; or it comprises DPnB and one or more cosolvents and no butylal.

Abstract: A heater is suitable to be arranged opposite and away from an upstream or downstream face of an exhaust gas purification member of a vehicle. The heater comprises a fastening ring with an electrically conductive frame having a geometric center, a central support arranged substantially at the geometric center of the frame, and a plurality of elongate heating elements each having first and second ends opposite one another. The first end is connected to the frame and the second end is connected to the central support. The fastening ring further comprises a plurality of electrically conductive radial protrusions distributed around the frame and protruding toward the outside of the frame.
