Proof-of-principle demonstration of a virtual flow meter-based transducer for gaseous helium monitoring in particle accelerator cryogenics.

A transducer based on a virtual flow meter is proposed for monitoring helium distribution and consumption in cryogenic systems for particle accelerators. The virtual flow meter allows technical and economical constraints, preventing installation of physical instruments in all the needed measurement points, to be overcome. Virtual flow meter performance for the alternative models of Samson [ http://www.

A software framework for developing measurement applications under variable requirements.

A framework for easily developing software for measurement and test applications under highly and fast-varying requirements is proposed. The framework allows the software quality, in terms of flexibility, usability, and maintainability, to be maximized. Furthermore, the development effort is reduced and finalized, by relieving the test engineer of development details.

Sarcoidosis of the thyroid: report of a case and a review of the literature.

A case of sarcoidosis involving the thyroid gland in a 75 year-old woman and a review of the literature are described. Fine-needle aspiration of the thyroid and a cervical lymph node was performed. Histological examination confirmed the cytological diagnosis.

[Investigation of the blood lipid profile of a school population in Piedmont].

The lipidaemic profile has been evaluated in a series of 603 healthy children aged 13-14, within a programme for the prevention of atherosclerotic disease commenced in November 1980 at Health Unit 66 of the Region of Piedmont. Hyperlipaemia is among the environmental risk factors for ATS and more than any of the others it regards paediatric age and can be acted upon. Analysis of the results shows that 172 subjects (28.

Pentoxifylline, total urinary protein excretion rate and arterial blood pressure in long-term insulin-dependent diabetic patients with overt nephropathy.

A specific hemorheologic treatment might reduce urinary protein excretion and the decline in kidney function in diabetic patients with overt clinical nephropathy. Twenty-one insulin dependent (type I) diabetic patients were randomized and assigned to a treatment with conventional antihypertensive therapy (protocol I) or with pentoxifylline (Trental 400) (protocol II). A marked improvement of blood rheology pattern, together with a reduction of urinary albumin excretion rate and total urinary protein excretion rate, was demonstrated throughout a 1-year follow-up study with pentoxifylline.
