An Anti-Perfect Dynamo Result [PDF]
It is shown that if the flow vector is a coordinate basis vector, then perfect dynamo action is not possible, regardless of whether the steady flow is compressible. Criteria determining the basis vector property are found to be expressible in terms of Lie derivatives, and construction of basis vector sets is straightforward.

What do global p-modes tell us about banana cells? [PDF]
We have calculated the effects of giant convection cells also know as sectoral rolls or banana cells, on p-mode splitting coefficients. We use the technique of quasi-degenerate perturbation theory formulated by Lavely & Ritzwoller in order to estimate the frequency shifts.

Acute Stroke due to Vertebral Artery Dissection in Giant Cell Arteritis
The diagnosis of giant cell arteritis (GCA) when presenting with atypical features such as stroke is very challenging. Only 0.17% of first-ever strokes are caused by GCA, a life-threatening condition when left untreated. Very few cases have been reported

Abstract Background People with rheumatoid arthritis (RA) are at increased risk of osteoporosis. The Australian Rheumatology Association RA Clinical Care Standard recommends fracture risk assessment at RA diagnosis and as clinically indicated. Aims The aim of this study was to evaluate the use of dual‐energy X‐ray absorptiometry (DEXA) for osteoporosis

Giant Cell Arteritis versus Takayasu Arteritis: An Update
Giant cell arteritis (GCA) and Takayasu Arteritis (TAK) are two systemic granulomatous vasculitides affecting medium- and large-sized arteries. Similarities in GCA and TAK regarding the clinical presentation, the systemic inflammatory response and the ...

Association between glucocorticoid therapy and incidence of diabetes mellitus in polymyalgia rheumatica and giant cell arteritis: a systematic review and meta-analysis [PDF]
Background: Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are almost always treated with glucocorticoids (GCs), but long-term GC use is associated with diabetes mellitus (DM).

Geometric Results for Compressible Magnetohydrodynamics [PDF]
Recently, compressible magnetohydrodynamics (MHD) has been elegantly formulated in terms of Lie derivatives. This paper exploits the geometrical properties of the Lie bracket to give new insights into the properties of compressible MHD behaviour, both with and without feedback of the magnetic field on the flow.
