Abstract: The invention relates to a method of detecting neutrophil extracellular traps in a sample of a biofluid, wherein the sample of the biofluid is supplied with a nucleic acid-selective dye, wherein, after the staining, a multitude of optical, particle-related measurements is determined in the sample within the absorption range of the dye, in each case as a tuple of a measurement of a first optical feature and a second optical feature, wherein measurements of the first optical feature are selected within a sub-range of all measured values of the first optical feature and those of the second optical feature within a sub-range of all measured values of the second optical feature, and wherein the number of selected measurements for detection of the neutrophil extracellular traps is compared to a predetermined borderline value.

Abstract: The invention relates to a safety device for firearms with a firing pin lock to prevent the unintended unlocking of the firearm. The safety device comprises a rotatable safety shaft connected to the firing pin lock with locking surfaces. The safety shaft is adjustable in at least two positions for locking at least the firing pin. The safety shaft, while securing the weapon, is fixed in such a way that any force applied to the safety wing cannot result in movement of either the safety wing or the safety shaft.

Abstract: The present invention provides a device wherein the safety is arrested in a position in that secures the weapon. The safety shaft, while securing the weapon, is fixed in such a way that any force applied to the safety wing cannot result in a movement of either the safety wing or the safety shaft.
