Opis:: We put forward a finite element method for static problems of cubic quasicrystals by variation of a suitable general potential functional. As an example we study a quasicrystal column containing a penny-shaped crack. The comparison with analytical results shows that the precision and efficiency of the numerical solution are satisfactory. The procedure can be used to solve more complicated boundary value problems and can be extended towards more sophisticated methods of crack tip loading analysis.

Opis:: In order to understand the roles of abscisis acid in soybean exposed to UV-C radiation, soybean seedlings were exposed to UV-C radiation and ABA was applied. The chlorophyll content, active oxygen metabolism and flavonoids content of soybean seedlings were investigated. The present study revealed that UV-C radiation significantly attenuated the chlorophyll content and suppressed PSII activity. It was observed that the contents of H2O2, malondialdehyde and O2 - were markedly increased, and the activities of antioxidant enzymes such as superoxide dismutase, peroxidase and catalase were enhanced, so were the flavonoids content, whereas the seedling height and biomass were significantly reduced. ABA application improved the activities of superoxide dismutase, peroxidase, catalase and the contents of flavonoids, decreased the contents of H2O2, MDA and O2 -, and also increased the chlorophyll content and enhanced PSII performance, thus enhancing biomass accumulation. The results suggested that ABA alleviated UV-C damage to soybean seedlings by reducing ROS generation and enhancing antioxidase activity. The isoflavones daidzin and genistein were significantly responsive to UV-C.

Opis:: By using the generalized Stroh formalism, the electric-elastic field induced by a straight dislocation parallel to a periodic axis of a one-dimensional quasicrystal is obtained. The derivation is concise and the solution is in an exact closed form. As an illustration, the electric-elastic fields around a straight dislocation in a one-dimensional hexagonal quasicrystal are studied. Besides the interesting numerical results presented, the generalized Stroh formalism can be applied to more complicated dislocation problems in quasicrystals.
