20. Ethylene response of tomato fruits to the minimum dropping.

Author

Ramina, Angelo, Chang, Caren, Giovannoni, Jim, Klee, Harry, Perata, Pierdomenico, Woltering, Ernst, Usuda, H., Kitagawa, M., Ito, Y., Umehara, H., Nakamura, N., Roy, P., Okadome, H., Ishikawa, Y., Satake, T., and Shiina, T.

Abstract

Physical stresses such as shock and vibration deteriorate the quality of fresh fruits and vegetables not only by direct physical damage but also through the endogenous biological activities of the produce. Ethylene seems to be the most important factor of the stress response in the produce. In this paper we study the effects of slight dropping (1, 3, 10 times) on the ethylene and CO2 production of the whole tomato fruits and accumulation of the ACC synthase (ACS) mRNA in the tissue. The mature green tomato (Lycopersicon esculentum) fruits which were screened by ethylene production rate (less than 0.2 μlkg??−1h??−1) were used to avoid a contamination of climacteric phase fruit.

21. Fatigue Crack Growth in Quenched Amorphous Polymers PC and PET.

Author

Gdoutos, E. E., Kitagawa, M., and Nishi, D.

Abstract

When tensile or shear test is performed in as-received(AR) or annealed samples of amorphous polymers, yielding occurs after the initiation of numerous slip lines near the peak stress and the subsequent formation and growth of a pair of visible shear bands. But in the case of ‘quenched' (Q) sample subjected to simple shear, yielding starts at the sudden initiation of vague shear bands without visible slip lines. The stress softening just after yielding is steeper in AR sample than in Q one. The plastic deformation mechanism seems to be very different between AR and Q samples. To know this difference may lead to the intrinsic understanding of the yield mechanism of amorphous polymers. In order to know the effect of quenching, mechanical and physical properties such as strain rate and temperature dependence of yield stress, dynamic properties, density, DSC and diffusion of kerosene have been measured. In this paper, effect of quenching on fatigue crack growth behavior involved with plastic zone in front of fatigue crack tip, crack growth rates and fracture surface was investigated using amorphous polymers PC and PET.
