Explosive Bodies and Mixtures

So (3) Invariance and Covariance in Mixtures of Simple Bodies

Abstract We adapt to mixtures the procedure of invariance of external power under the action of SO (3) to deduce balance equations. The two classical axioms about the growths of momentum and moment of momentum are derived with the help of a rule on the structure of the total power. We discuss also the covariance of the balance equations of each constituent and the nature of the constituent stress.

Demixing behavior in two-dimensional mixtures of anisotropic hard bodies.

Scaled particle theory for a binary mixture of hard discorectangles and for a binary mixture of hard rectangles is used to predict possible liquid-crystal demixing scenarios in two dimensions. Through a bifurcation analysis from the isotropic phase, it is shown that isotropic-nematic demixing is possible in two-dimensional liquid-crystal mixtures composed of hard convex bodies. This bifurcation...

Explosive Volcanism on Atmosphere-less Bodies - a Comparison of the Moon, Mercury and Io

Introduction: There is abundant observational evidence of explosive volcanism on all three of the large airless silicate-dominated bodies, the Moon [1], Mercury [2] and Io [3]. The lack of atmospheres makes analysis of explosive activity relatively simple. We combine the results of earlier analyses of explosive volcanism to draw inferences about the geologic circumstances of explosive activity ...

Arthroscopic removal of metal foreign bodies from the knee joint after explosive war injuries.

The results of arthroscopic removal of metallic fragments from knee joint due to explosive war injuries are presented. In period from 1991-1995 during war in Croatia we have operated 25 knee joints. Indications for arthroscopy were based on radiographic and clinical findings. The foreign bodies in the joint were found in 19 patients while additional 6 had foreign bodies in the periarticular sof...
