II rn 3 7 i Solute-solvent and solvent-solvent interactions in binary solvent mixtures. Part 3. The ET(30) polarity of binary mixtures of hydroxylic solvents

The most important features of the proposed spherical gravitational wave detectors are closely linked with their symmetry. Hollow spheres share this property with solid ones, considered in the literature so far, and constitute an interesting alternative for the realization of an omnidirectional gravitational wave detector. In this paper we address the problem of how a hollow elastic sphere interacts with an incoming gravitational wave and find an analytical solution for its normal mode spectrum and response, as well as for its energy absorption cross sections. It appears that this shape can be designed having relatively low resonance frequencies (ϳ 200 Hz͒ yet keeping a large cross section, so its frequency range overlaps with the projected large interferometers. We also apply the obtained results to discuss the performance of a hollow sphere as a detector for a variety of gravitational wave signals. ͓S0556-2821͑97͒00522-5͔PACS number͑s͒: 04.80.Nn, 95.55.Ym

Measurements of νE for binary mixtures of CmH2m+1CO2CH3 (m = 1,2,3) + CnH2n+1(OH) (n = 2,3,4,5) are reported. The results have been determined by using the densities obtained in a vibrating tube densimeter at 298.15 K, they are positive for all these systems. The data have also been compared with available literature values with a discussion on these mixtures. Keywords: excess molar mixtures, methyl alkanoates, normal alkanols.
