Is SUSY accessible by direct dark matter detection?

We performed a combined analysis of the parameter space of the Minimal Supersymmetric Standard Model (MSSM) taking into account cosmological and accelerator constraints including those from the radiative b → sγ decay measured by the CLEO collaboration. Special attention is paid to the event rate, R, of direct dark matter neutralino detection. We have found domains of the parameter space with R - 5 ? 10 events/kg/day. This would be within the reach of current dark matter experiments. The b → sγ data do not essentially reduce these large event rate domains of the MSSM parameter space.     

Spontaneous concentration waves in the belousov-zhabotinskii reaction in viscous solutions

It is shown that the range of values of the parameters of the spontaneous oscillations in the Belousov-Zhabotinskii reaction (bromate + malonic acid + o-phenanthroline complexes of iron(II, III) + sulfuric acid) remains unchanged when viscous solutions are used. Silica gel was used as an inert thickening agent. The absence of any appreciable retardation of the oscillations when the viscosity of the solution is increased shows that the gel employed does not produce any appreciable retardation of the rate of diffusion of low-molecular compounds, which determines the rate of the oscillations.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 26, No. 4, pp. 493–497, July–August, 1990.The authors are grateful to L.

An approximate method of solving dynamical problems of thermoviscoelasticity

A generalization of Whitham's asymptotic method is proposed for solving systems of integro-differential equations describing the dynamic behavior of bodies composed of nonlinear viscoelastic materials. The possibility of using this approach to solve coupled problems of thermoviscoelasticity is indicated. A number of examples are considered including the propagation of a harmonic disturbance in a rod of nonlinear viscoelastic material under isothermal conditions and the coupled problem of the high-frequency vibration of a rod of linear viscoelastic material, whose properties depend on temperature in accordance with the time-temperature superposition principle.Institute of Mechanics, Academy of Sciences of the Ukrainian SSR, Kiev.
