Colloidal particles at fluid interfaces: Effective interactions, dynamics and a gravitation–like instability
Colloidal particles of micrometer size usually become irreversibly trapped at fluid interfaces if they are partially wetted by one phase. This opens the chance to create two–dimensional model systems where the...

Collective dynamics of colloids at fluid interfaces
The evolution of an initially prepared distribution of micron-sized colloidal particles, trapped at a fluid interface and under the action of their mutual capillary attraction, is analyzed by using Brownian dy...

Open AccessEffective interactions of colloids on nematic films
The elastic and capillary interactions between a pair of colloidal particles trapped on top of a nematic film are studied theoretically for large separations d. The elastic interaction is repulsive and of quadrup...

Nucleon form factors from a covariant quark core: Limits in their description
In treating the relativistic 3-quark problem, a dressed-quark propagator parameterization is used which is compatible with recent lattice data and pion observables. Furthermore 2-quark correlations are modeled...

Current conservation in the covariant quark-diquark model of the nucleon
The description of baryons as fully relativistic bound states of quark and glue reduces to an effective Bethe-Salpeter equation with quark-exchange interaction when irreducible 3-quark interactions are neglect...

Nucleon properties in the covariant quark-diquark model
In the covariant quark-diquark model the effective Bethe-Salpeter (BS) equations for the nucleon and the Δ are solved including scalar and axial vector diquark correlations. Their quark substructure is effectivel...

Estrogens and Antiestrogens in the Male
Estrogens and men - this is a topic which has been neglected for quite some time and it is only relatively recently that discussion of it has intensified remarkably. The discussion has not been restricted to t...

Embryotoxic Effects of Post-Coital Fertility Inhibiting Steroids
In mice post-coital estrogens caused retardation of tubal egg cleavage, whereas post-coital progestins stimulated egg division. In rats the situation was reversed. In this species estrogens accelerated the tub...
