Surface tension of nuclear matter

The surface tension sigma and the surface density thickness t of nuclear matter have been calculated in the Fermi-gas model, the nucleons moving in a self-made shell model potential with a realistic slope and velocity dependence ( parameters alpha and beta ). One gets the experimental values for sigma and t with alpha and beta agreeing with earlier data

The Role of National Courts in International Trade Relations

Part I of this article identifies and analyzes some modern trends in judicial review in the area of international relations. Section Part II then examines and briefly discusses the existence of judicial review for both national and international levels of protection and the possibilities for linking the two. A major part, Part III, is devoted to the specific role of national courts within the WTO system. Finally, Part IV draws conclusions and suggests some means for improving the judicial review offered by national courts and for linking them to the interstate dispute settlement on the international level

Paradoxical Magnetic Cooling in a Structural Transition Model

In contrast to the experimentally widely used isentropic demagnetization process for cooling to ultra-low temperatures we examine a particular classical model system that does not cool, but rather heats up with isentropic demagnetization. This system consists of several magnetite particles in a colloidal suspension, and shows the uncommon behavior of disordering structurally while ordering magnetically in an increasing magnetic field. For a six-particle system, we report an uncommon structural transition from a ring to a chain as a function of magnetic field and temperature.Comment: 3 pages, 2 figures.
