Effect of Xerostomia on the Functional Capacity of Subjects with Rheumatoid Arthritis.

Objective: To evaluate the intensity of xerostomia and hyposalivation in subjects with rheumatoid arthritis (RA) as well as the effects of these conditions on functional incapacity and disease activity.

Methods: The study sample comprised 236 individuals of both sexes who had RA. All the individuals were submitted to clinical evaluation and unstimulated sialometry.

Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory.

Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with [Formula: see text] eV by analyzing cosmic rays with energies above [Formula: see text] eV arriving within an angular separation of approximately 15[Formula: see text]. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution.
