[en] The problem of the high level dimensional to be obtained for the construction of these coils is a fundamentally important element in terms of the correct functioning of the whole magnet. In order to achieve this objective specific methodologies and tools for production and control were studied and applied to have the desired results with completely satisfactory results. With machining practically finished one can now synthesize the experience gained describing the more important results and the methods used, showing: the importance of the precision required in relation to operational functioning; the manufacturing solutions adopted and the operative measuring modalities; and the values and the deviations obtained

[en] Ansaldo is manufacturing 326 quadrupoles for the ESRF Storage Ring. After manufacturing design phase, four prototype quads have been built and tested in Ansaldo workshops. Once verified the reliability of the design and improved the manufacturing process for the full production, Ansaldo is now delivering the magnets at high production rate. This paper describes some relevant aspects of the design and summarizes by the data recorded during three test campaigns the improvement process of the quadrupoles up to the goal

[en] This article shows the method analithic, results gained from determination from crystal by struvite meet with incrustation in bars the iron, that constitute the rasper from drain by excrement and rest by food from barnyard by pigs. Too describe the transformation from this minerals to newberyte, when expose to daylight and discuss the genetic from this minerals. (author)

[en] The submandibular and sublingual glands of rats are surgically exposed and irradiated by X-ray. A simulated group with surgical exposition of the glands is performed. In the irradiated submandibular glands occurred atrophy, architectural disorder and degenerative processes. RNA reduction in the nucleus, nucleolus and cytoplasm of the acini cells and a decrease of protein synthesis are described. (M.A.C.)

[en] The authors report the observations derived from CT evaluation of 19 cases of lumbosacral conjoined nerve roots; 11 of these have been confirmed by lumbar myelography and/or at surgery. They conclude that CT without intrathecal metrizamide allows the recognition in most cases the presence of conjoined nerve roots and to differentiate them from a herniated disk fragment; this is especially usefull avoid surgical damage of anomalous roots.

[en] From June 1985 to September 1986, eight patients affected by sacrococcygeal chordoma were examined by means of conventional radiography and tomography first, and then by highresolution CT. All patients underwent surgery and an histologic examination of the surgical specimen was carried out. CT always allowed to detect the sacro-coccygeal neoplasm, which looked like solid non-homogeneous mass; in 50% of cases coarse calcifications were found. CT made it possible to evaluate the growing side of the tumor, its relation with the adjacent anatomical structures-especially the longitudinal extension and the involvement of the sacral hiatus; these findings proved to be very useful in order to choose the most appropriate surgical technique. CT findings also suggested the nature of the tumor but rarely allowed a definitive diagnosis CT is, at any rate, mandatory in order to evaluate the real extent of the tumor and to plan surgery

[en] A total of 42 patients with myopathies underwent CT scans in order to study the relationship between CT images and clinical findings. CT is a valuable diagnostic aid to distinguish primary from neurogenic myopathies, to facilitate directed biopsy and finally to classify the disease according to the degree and extent of the muscular lesion.
