Our previous " exotic " particle, together with the more recent anomalous anyon model (which has arbitrary gyromagnetic factor g) are reviewed. The non-relativistic limit of the anyon generalizes the exotic particle which has g = 0 to any g. When put into planar electric and magnetic fields, the Hall effect becomes mandatory for all g = 2, when the field takes some critical value.

Letting the mass depend on the spin-field coupling as M 2 = m 2 − (eg/2c 2)F αβ S αβ , we propose a new set of relativistic planar equations of motion for spinning anyons. Our model can accommodate any gyromagnetic ratio g and provides us with a novel version of the Bargmann-Michel-Telegdi equations in 2 + 1 dimensions. The system becomes singular when the field takes a critical value, and, for...

Dynamical (super)symmetries of monopoles and vortices (1) Abstract. The dynamical (super)symmetries for various monopole systems are reviewed. For a Dirac monopole, no smooth Runge-Lenz vector can exist; there is, however, a spectrum-generating conformal o(2, 1) dynamical symmetry that extends into osp(1/1) or osp(1/2) for spin 1/2 particles. Self-dual 't Hooft-Polyakov-type monopoles admit an ...

Nurses' Work Time Distribution at Emergency Service Distribución Del Tiempo De Trabajo De Las Enfermeras En Unidad De Emergencia

The objective of this quantitative, descriptive, case study was to identify and analyze the distribution of nurses' work time at an emergency service. To do this, the work sampling method was used. The nursing activities performed by the studied nurses were identified by evaluating the patient care forms and by direct observation of nurses during their everyday work routine at the service. The ...
