Abstract Low-quality water and soil salinization are increasingly becoming limiting factors for food production, including olive – a major fruit crop in several parts of the world. Identifying putative salinity-stress tolerance in olive would be helpful in the future development of new tolerant varieties. In this study, novel salinity-responsive biomarkers (SRBs) were characterized in the species, namely, monooxygenase 1 (OeMO1), cation calcium exchanger 1 (OeCCX1), salt tolerance protein (OeSTO), proteolipid membrane potential modulator (OePMP3), universal stress protein (OeUSP2), adaptor protein complex 4 medium mu4 subunit (OeAP-4), WRKY1 transcription factor (OeWRKY1) and potassium transporter 2 (OeKT2). Unique structural features were highlighted for encoded proteins as compared with other plant homologues. The expression of olive SRBs was investigated in leaves of young plantlets of two cultivars, ‘Nabali’ (moderately tolerant) and ‘Picual’ (tolerant). At 60 mM NaCl stress level, OeMO1, OeSTO, OePMP3, OeUSP2, OeAP-4 and OeWRKY1 were up-regulated in ‘Nabali’ as compared with ‘Picual’. On the other hand, OeCCX1 and OeKT2 were up-regulated at three stress levels (30, 60 and 90 mM NaCl) in ‘Picual’ as compared to ‘Nabali’. Salinity tolerance in olive presumably engages multiple sets of responsive genes triggered by different stress levels.

Two Parameter

A two-parameter fracture criterion previously applied to flat plates has been extended to cylindrical and spherical shells. It is applicable to all modes of fracture including net section stress levels above yield. The predictive capability is such that the calculated stress at failure for 85 percent of the data examined, was within 10 percent of the experimental values. Furthermore, 96 percent were within 15 percent of the experimental values.

This paper discusses the sealing behavior of gaskets according to the gasket testing procedure HPIS Z104 established in Japan. The testing procedure consists of eleven gasket stress levels while the internal pressure is constant. It takes about 3 hours to complete one test, which is acceptable for gasket manufacturers. The test method is going to be effective as the Japanese Industrial Standard (JIS) soon. Several sheet gaskets and spiral wound gaskets were tested based on the test method HPIS Z104 and test results are compared and discussed in this paper. Based on the test results, experimental formulas are proposed to approximate the sealing behavior of gaskets. It is shown that the sealing behavior of gaskets can be well characterized using the proposed testing procedure and the experimental formulas. The formulas have the possibility of application to the design of gasketed bolted flanged connections. It is also shown that the sealing performance of spiral wound gaskets with graphite and PTFE fillers is as good as that of sheet gaskets under an equal gasket load.

Brush seals are complex structures having variety of design parameters, all of which affect the seal behavior under turbine operating conditions. The complicated nature of the seal pack and frictional interactions of rotor, backing plate and bristles result in nonlinear response of the brush seal to variances of design parameters. This study presents CAE based characterization of brush seals, which aims to investigate the main effects of several brush seal design parameters on brush seal stiffness and stress levels. Characterization work of this study includes free-state rotor rub (unpressurized seal), steady state (pressure load without rotor interference) and pressurized-rotor interference conditions.
