Caregiver Perspectives on the Burden of Disease and Treatment in Uncontrolled Gout
Arthritis Care &Research, EarlyView.Objective Uncontrolled gout (UG) refers to persistently elevated serum urate (SU) levels >6 mg/dL and ongoing gout symptoms despite use of urate‐lowering therapy (ULT). The objective of this study was to evaluate the burden associated with informal caregiving for individuals with UG.

The development of advanced creep constitutive equations for high chromium steel P91 at low stress range [PDF]
, 2013 Diffusion dominates the creep deformation at low stress range for high chromium steel P91. Brittle creep fracture is caused by cavity nucleation, growth and coalescence of cavities and large precipitates (Laves phase and M23C6) at grain boundary under ...
