An experimental test for effective medium approximations (EMAs)

The effective medium approximations: Some recent developments

We provide a brief and highly selective review of the Landauer– Bruggeman effectivemedium approximation as applied to random composite media. We first discuss this approximation as applied to linear composites, i.e., to those materials in which there is a linear relation between a curl-free electric field and a divergence-free current density. We then describe extensions of this approach to ran...

Possible Experimental Test of Continuous Medium Model for Fractal Media

We use the fractional integrals to describe fractal media. We consider the fractal media as special (”fractional”) continuous media. We discuss the possible experimental testing of the continuous medium model for fractal media that is suggested in Phys. Lett. A. 336 (2005) 167-174. This test is connected with measure of period of the Maxwell pendulum with fractal medium cylinder. PACS: 03.40.-t...

An experimental evaluation of two effective medium theories for ultrasonic wave propagation in concrete.

This study compares ultrasonic wave propagation modeling and experimental data in concrete. As a consequence of its composition and manufacturing process, this material has a high elastic scattering (sand and aggregates) and air (microcracks and porosities) content. The behavior of the "Waterman-Truell" and "Generalized Self Consistent Method" dynamic homogenization models are analyzed in the c...

An Effective Growth Medium for Probiotics for Strict Vegetarians

Development of MMRS (modified MRS Agar) culture medium; the absolute vegetarian culture medium containing plant seed powder in place of beef extract for the growth of probiotics. Vegetarian probiotic foods by definition must be free from all animal-derived ingredients. This research provides an alternative efficacious, cost effective vegetal culture medium. The culture medium developed in prese...
