The purpose of the work was to study the nosological structure of rheumatologic patients hospitalized  in emergency hospitals. The analysis of the obtained distribution and its comparison with the structure  of patients at the Scientific Research Institute of emergency care named after I. I. Djanelidze and the City  Rheumatology Center were done. Determination of the current structure of hospitalization of rheumatologic  patients can serve as a basis of its forecasting for the subsequent periods.

The Welfare State

The provision of taxation relief to support pension savings has become a large and expensive aspect of the welfare state in many countries. Among OECD member states this exceeds $200 billion in revenue forgone each year. Previous research has consistently found this fiscal welfare to have pronounced regressive distributive outcomes. However, little is known about the gendered impact of these fiscal welfare supports, a void this article addresses. Using data for Ireland the article finds that the current structure of fiscal welfare supports notably favours males over females. Nominal contribution levels are higher among males, and males are more likely to be active contributors to pension savings. The associated tax supports are consequently skewed, with two-thirds received by men and one-third by women. This outcome suggests a continuation of the gender earnings gap into retirement and a discontinuity between longevity expectations and tax policy supports for pension provision.

The Magnetic Field

The prominence of nulls in reconnection theory is due to the expected singular current density and the indeterminacy of field lines at a magnetic null. Electron inertia changes the implications of both features. Magnetic field lines are distinguishable only when their distance of closest approach exceeds a distance $\varDelta _d$ . Electron inertia ensures $\varDelta _d\gtrsim c/\omega _{pe}$ . The lines that lie within a magnetic flux tube of radius $\varDelta _d$ at the place where the field strength $B$ is strongest are fundamentally indistinguishable. If the tube, somewhere along its length, encloses a point where $B=0$ vanishes, then distinguishable lines come no closer to the null than $\approx (a^2c/\omega _{pe})^{1/3}$ , where $a$ is a characteristic spatial scale of the magnetic field. The behaviour of the magnetic field lines in the presence of nulls is studied for a dipole embedded in a spatially constant magnetic field. In addition to the implications of distinguishability, a constraint on the current density at a null is obtained, and the time required for thin current sheets to arise is derived.

Transverse Oscillations

Although most magnetic neutral points occurring in nature seem to form part of a continuum, recent studies of reconnection have centred on static equilibria in the neighbourhood of an isolated three-dimensional null point. The linear stability of this configuration is studied here. It is found that one may choose a flux surface so that transverse oscillations localized around the surface and polarized within it must grow exponentially in time. This means that any static equilibrium containing an isolated three-dimensional null point is linearly unstable.
