Abstract
PURPOSE: To analyse thyroid carcinomas having an extrathyroid extension in order to identify the principal prognostic factors and outline an effective therapeutic strategy.
METHODS: We selected a sample of 160 patients suffering from locally advanced "well differentiated thyroid carcinoma (T4) who had undergone surgery at the Department of Surgery of University of Rome "La Sapienza". The sample was subdivided into three groups: T4, limited type I, and extensive type II, T4 microcarcinomas.
RESULTS: We obtained excellent results with the T4 microcarcinomas, above all in patients under the age of 45, with a 94.5% survival rate, compared with 88% in patients aged over 45. In the extensive type II T4 carcinoma we obtained a survival rate of 29.4% in patients aged over 45 years.
CONCLUSIONS: Age, combined with an aggressive histological variant (Sclerosing and tall-cell papillary carcinoma), is an important factor in prognosis. The radicality of surgical excision is considered an important prognostic factor, although the results reported in the literature are contradictory. Aggressive surgery can free from the disease a high percentage of patients over the age of 50 even with T4. We deem it fundamental to perform total thyroidectomy in all advanced cases of thyroid neoplasm and to extend neoplasm excision to the adjacent tissues, even involving justified surgical demolition.

The role of educative thought in the life and work of Antonio Gramsci
No full textMany philosophers have propounded a vision of an improved society, what distinguishes Antonio Gramsci is his continuous effort to make it happen by understanding the process in order to put into practice. Gramsci's conviction about the importance of educative development came from both theory and experience. While there has been considerable examination of Gramsci's work in relation to the Prison Notebooks, this study will seek to address a lacuna in Gramsci scholarship. Using Gramsci's philological method, I analyse Gramsci's pre-prison activity; his pre-prison articles and letters, which, together with his letters from prison, formed part of his educative mission. This educative process was necessary, in order to construct a new party which would develop a collective will, collaboratively, with the masses.In this study therefore, I explore the contexts and formative experiences of the first part of his life together with the intellectual sources from which Gramsci developed his later theories, making central hitherto underemphasised connections between them which informed his writing and ideas. I intend to illustrate that Gramsci's underlying purpose in his writing, and political activity, was not only practical, on how to create a new socialist ruling class, but also educative in forming the mindset and values of his comrades. So that in addition to outlining his vision of a new order, he implicitly guided or explicitly explained the processes by which the necessary changes in social relations and moral climate could be made in order to achieve it. Each person had to engage with the values of the new order so that each could contribute to the construction of a new robust state. It was essential to build a hegemony at the most profound level, one which was dependent on collective understandings and a collective will

Comparison of Constitutive Laws for Modeling High-Temperature Superconductors
No full textThis paper investigates the conditions of use and the equivalence of various constitutive laws used to model the electromagnetic behavior of high-temperature superconductors: two versions of the critical state model (CSM), the power law model, and a so-called percolation model. All these models can be used to represent the same superconducting material with some limit of accuracy. The CSM and the power law model are well known in the literature. The percolation model can be seen as a generalization of the power law model that includes also a CSM-like behavior at very low electric fields. The investigation has been carried out for three types of operating conditions: the sudden application of a dc excitation, a pure ac excitation, and combined dc and ac excitations. The equivalence between the different constitutive laws is shown to be a function of the magnitude of the electric fields and of the time scales involved. In the dc case, long time scales and very small electric fields are predominant; thus, the superconductor requires a model that is accurate at low electric fields, such as the percolation model. The losses then arise from the relaxation of the magnetic field in the sample. In the ac case, the power law and percolation models are nearly identical when considering power frequencies, so choosing the simpler power law model is fully acceptable in practice. In addition, the CSM coincidentally provides good predictions of the losses in the power frequency range. In the dc+ac case, when time scales in the range of minutes to hours are considered, it is shown that ac losses dominate over relaxation losses, and the same conclusions as for the ac case apply
