(0.79 − x)Pb(In1/2Nb1/2)O3–0.21Pb(Zn1/3Nb2/3)O3–xPbTiO3 (x = 0.23–0.35) ternary ferroelectric system in the form of ceramics have been synthesized. Its structure and properties have been studied by X-ray powder diffraction and electric measurements. A morphotropic phase boundary ...
Pb commonly inhibits growth when it is at a concentration in the soil of 30 mg/kg or more but several Pb tolerant plants have been reported. However, few studies have focused on plant response to Pb exposure, particularly at concentrations higher than 30 mg/kg....

Also, the full \\(^{207}\\) Pb chemical shift tensor in cerussite at room temperature is determined from these data, with the eigenvalues being \\(\\delta _{11} = (-2315\\pm 1)\\) ppm, \\(\\delta _{22} = (-2492 \\pm 3)\\) ppm, and \\(\\delta _{33} = (-3071 \...
Full size image AsCalpBmutations do not block border cell migration completely, the possibility emerged that the other calpain gene, i.e.CalpA,may also be involved in the process. To test this hypothesis, egg chambers fromCalpA808/Df(2R)ED3716CG2transheterozygous flies were investigated. Although...
