Devolatilization of polymer resins
Commercial silicon resin was devolatilized by vacuum distillation, cured at room temperature and tested favorably for outgassing criteria. Applications of the devolatilized resin are potting compounds and conformal coatings
Coherent States and Geometric Phases in Calogero-Sutherland Model
Exact coherent states in the Calogero-Sutherland models (of time-dependent
parameters) which describe identical harmonic oscillators interacting through
inverse-square potentials are constructed, in terms of the classical solutions
of a harmonic oscillator. For quasi-periodic coherent states of the
time-periodic systems, geometric phases are evaluated. For the
Calogero-Sutherland model, the phase is calculated for a general coherent
state. The phases for other models are also considered.Comment: To appear in the Int. J. Mod. Phys.
Solutions of Conformal Turbulence on a Half Plane
Exact solutions of conformal turbulence restricted on a upper half plane are
obtained. We show that the inertial range of homogeneous and isotropic
turbulence with constant enstrophy flux develops in a distant region from the
boundary. Thus in the presence of an anisotropic boundary, these exact
solutions of turbulence generalize Kolmogorov's solution consistently and
differ from the Polyakov's bulk case which requires a fine tunning of
coefficients. The simplest solution in our case is given by the minimal model
of and moreover we find a fixed point of solutions when
become large.Comment: 10pages, KHTP-93-07, SNUCTP-93-3
