In a long-term test, the water uptake capability of the pumice according to the invention was firstly examined.

The advantages of filtration using a vacuum system were confirmed in a long-term test with clear water.

The next step is to carry out a long-term trial with cyclodextrins.

This long-term test is continued for another 5,000 hours.

This can now be investigated as part of this unique long-term study.

Experiment 7 is a long-term experiment.

The effectiveness of the secondary ice growth mechanism is demonstrated in a longtime experiment carried out on partially water saturated clayey sandstone.

Six such species are tested in a long-term field experiment near Mutrux (Canton of Vaud).

In a long term experiment with various long-tillage methods, the availability of selected macronutrients and the pH-value of the topsoil were investigated.

The researchers examined the effect of permanent seawater contact on selected plastics in a long-term test.

The "pitch drop experiment" is a well-known long-term experiment that was started in 1930 and still continues to this day.

In a long-time test over four weeks, 3-amino-5-heptyl-1,2,4-triazole was tested together with other inhibitors, and the corrosion rates were determined on a copper pipe by pumping the test water under identical conditions through a test zone.

In a long-term experiment, a 1 mm tantalum sheet saturated with copper at 400° C., coated with a layer of approximately 1 ?m of Pd/Cu alloy (40 atomic percent: 60 atomic percent) was kept in vacuum at 400° C. for 4,000 hours.

The graph according to FIG. 3 shows the results, obtained with such an arrangement, namely a sublimator filled with ferrocene pellets in the venting of the crankcase, with respect to the burn-off behavior of the diesel particulate filter in a long time test conducted for 20 hours.

This catalyst was tested in the manner of Example 1 in a long-term trial of 3 months, which had the following result:

A long-term experiment over 8 days with various temperature programs shows that the conversion increases sharply with increasing temperature, and the selectivity falls only at above 300° C. (Table 5).

For comparison purposes, FIG. 4 shows a long time test on the burning behavior of diesel particulate filter 11 under conditions comparable to those on which the diagram of FIG. 3 is based, with the single difference that no additive was added to the combustion air by means of a carrier gas stream from the venting of the crankcase.

Regeneration experiments were only partly successful, since the mechanical stability of the supported catalysts also decreased significantly in the long-term test.

After addition of 8 ml of propylene glycol, stability and sterility (microorganism count less than 100 microorganisms/g) were observed at room temperature in a long-term test.

In a long-term test, a mixture of acrolein and n-octanal with ammonia in a molar ratio of 1:1:3 was reacted over catalyst E at 400° C. with a WHSV of 3 h-1 in the reactor described above.

As we believe that operators of blast furnaces will have an immediate interest - at least in the short or medium-term - in charges of up to 50 fo formed coke, we have decided to carry out the long-term test on the basis of a 50 fo formed coke charge and 70 cr:P coke units.

The long-term test with the new type of short coupling with nil flexibility being carried out at Bergbau-Forschung was completed to our satisfaction.

Only one study is known (carried out in the USA) in which long term testing of a full scale pavement has been used to compare the wear effects of the two tyre types.

The reference system R3 is therefore suitable only for the VCI corrosion protection of steel, while the VCI oil VCI (3) according to the invention, as shown in the example, exhibits reliable VCI properties on all customary utility metals in long-term testing even under the extreme humidity conditions.
