Coupling between pressurized gas sorption and tensile behavior was studied in several semi-crystalline polymers: a Polyethylene (PE), a Polyamide 11 (Pand) and multi-layer systems based on these two materials were tested in tension into hydrogen (30 bars) and nitrogen (30 bars) atmosphere and compared to experiments into atmospheric air.
Nitrogen (black bars; 1N) or no nitrogen (white bars; 0N) was added to rice plants one day before inoculation with the indicated isolate of M. oryzae.
Nitrogen (black bars; 1 N) or no nitrogen (white bars; 0 N) was added to wheat plants one day before inoculation with the BR32 isolate of M. oryzae (see Methods).

The air was pumped through a Tenax GA trap, desorbed at 180°C and transferred to an AT 5 column under a flow of 2.5 ml/min nitrogen (3.7 bars; quality 5).
The optimum cutting was achieved during pulsed mode at applied power 210 W, frequency 200 250 Hz, speed 1 1.5 m/min, focus position −0.5 to −1 mm, nitrogen pressure 9 11 bar and oxygen pressure 2 4 bar.
Initially, the chamber was pressurised with nitrogen to 50 bar or up to 90 bar for the long tests, respectively (≥24 h).
Suspension Type: Front: Modified MacPherson strut type, linear rate front springs, tubular stabilizer bar, nitrogen gas-pressurized Tokico absorbers.
The reactor was initially pressurised with nitrogen at 55 bar.
