ductance of layer. These dependencies showed that hybridization appears when sheet conductance of layer (σ) exceeds some critical value σcr), the magnitude of which changes in wide range and depends on material and plate orientation. For example, for aforementioned hybrid pair A0 SH0 in potassium niobate σcr = 10−3S. If σ < σcr modes are not coupled, i.e. their dispersion curves do not repulse....
متن کاملOral Session 03: CNS Risk
Exposure to space radiation may have impacts on brain function, either during or following missions. It is most important to determine how low doses of protons and high-LET irradiation elicit changes in brain function. Within this framework, the role of oxidative stress should also be assessed, as well as other possible interaction mechanisms involving, e.g., genetic, environmental, and sex-dep...

The hemisynthesis of the title compound, C22H32O2, was carried out through direct acetyl-ation reaction of the naturally occurring diterpene totarol [systematic name: (4bS,8aS)-4b,8,8-trimethyl-1-propan-2-yl-5,6,7,8a,9,10-hexa-hydro-phen-an-thren-2-ol]. The mol-ecule is built up from three fused six membered rings, one saturated and two unsaturated. The central unsaturated ring has a half-chair...

The title compound, C27H34O2, was hemisynthesized through direct benzoyl-ation of the naturally occurring meroterpene totarol. The central fused six-membered ring has a half-chair conformation, whereas the terminal six-membered ring displays a chair conformation. The dihedral angle between the fused benzene ring and the benzoyl benzene ring is 73.05 (14)°. The S,S chirality of the mol-ecule is ...
