Multifilamentary Superconductors

The influence of the filament microstructure on the critical current density values, Jc, of Nb-Ti multifilamentary superconducting composites has been well documented. However the development of these microstructures during composite processing is still under investigation.During manufacture, the multifilamentary composite is given several heat treatments interspersed in the wire-drawing schedule. Typically, these heat treatments are for 5 to 80 hours at temperatures between 523 and 573K. A short heat treatment of approximately 3 hours at 573K is usually given to the wire at final size. Originally this heat treatment was given to soften the copper matrix, but recent work has shown that it can markedly change both the Jc value and microstructure of the composite.

Treatment Principles

The era where surgical excision alone was the sole treatment of venous malformation (VM) is now over. A multidisciplinary approach that utilizes both traditional surgical therapy and endovascular therapy is now the standard of care. Endovascular therapy utilizing primarily both embolization therapy and sclerotherapy is the treatment of choice for surgically ‘inaccessible' VM lesions. Surgical therapy of VM lesions has been shown to be more effective when combined with supplemental endovascular therapy.

To the Editor.— I just finished reading the article by Wung et al Pediatrics 1985;76:488-494). I was quite surprised at the publication of this article. There are several problems that make it such that I question its appropriateness in the article section of Pediatrics. The most important objection is that it is a retrospective collection of patients who were treated by some general treatment plan with no prospective analysis or control group. The data collected are dubious at best; for example, the authors do not state where the O2 samples were drawn and they do not define what they mean by the patient's oxygenation being improved with tolazoline.
