Abstract: In a stacker, a mail item to be stacked is propelled against a stop wall at a stacking point by a stacking roll. A controlled driven underfloor belt and a stack support are displaced from the stack as the stack grows. The mail item to be stacked meets the preceding, already stacked item at an acute angle. Before it is stacked the mass of each item is determined. Stacking forces are measured with a measurement device in a preceding test phase the target values for the stacking pressures and the braking curve of the stacking roll up until the mail items have reached the stop are defined and stored based on statistical analyses in accordance with the mass of the mail items to be stacked. The speed of the respective mail item is reduced according to the braking curve assigned to the determined mass of the mail item.

Abstract: The invention relates to a method of a mass-spectrometric analysis of known mutation sites in the genome, such as single nucleotide polymorphisms (SNPs), using the method of restricted primer extension. The invention consists of the use of primers with a photocleavable linker. The linker creates a gap in a DNA strand which is almost the same size as a natural DNA building block (nucleoside). The linker forms a bridge over a base pair without inhibiting hybridization or enzymatic extension. However, the linker allows the primers to be cleaved after extension in order to obtain short DNA fragments which can be more easily detected on the mass spectrometer.
