Evaluation of the magnetization direction effects on ferrite PM brushless fractional machines
No full textPermanent magnets are frequently adopted in small brushless machines for automotive applications. Normally anisotropic ferrites, but some research on bonded magnets is being carried on. Several types of magnetization can be proposed, involving different levels of complexity in the magnetization process. In the paper a comparison between parallel and radial magnetization is described, taking into account on one side the major complexity of the radial process and on the other the small power derating of the paralle
No deportation but no leniency here: Multi-faceted bordered penality in Italy
No full textThe chapter delves into Italy's pivotal role as a critical European gateway in the Central Mediterranean, strategically positioned for sea arrivals and transit to Northern and Central Europe. Despite the perceived leniency in its migration enforcement system, marked by discretion and limited deportation, Italy's border control reveals a complexity that goes beyond initial impressions. Focusing on the concept of “bordered penality", the chapter argues that the enforcement system, grappling with the significant presence of non-deportable migrants, leads to a continuous movement among various confinement sites. The authors highlight the inhumane and pervasive control mechanisms experienced by migrants, as they shift between pre-removal detention centres, hotspots, reception centres, and prisons, resulting in differential inclusion. The chapter traces the historical evolution of arrivals in Italy, emphasizing the geopolitical significance and economic labour market implications. It scrutinizes the shortcomings of deportation practices and delineates the continuum of confinement for undeported migrants. Ultimately, the chapter asserts that Italy's bordered penality, encompassing detention and containment practices, effectively responds to the country's unique political, economic, and geopolitical situation

A case of oat-cell carcinoma of the rectum prompted the authors to undertake a review of the literature. The main histological aspects allowing an accurate diagnosis are stressed. This is a rare form of highly malignant neoplasm of
uncertain origin (probably similar to that of carcinoids) with a very marked tendency to metastasize, even to distant organs; it is characterized by substantial cellular polymorphism with small-sized elements, very little cytoplasm, a large hyperchromic nucleus, barely visible nucleoli and
histochemical reactions typical of neuroendocrine cells

Leiomyosarcoma of the small intestine is a malignant mesenchymal tumour composed of smooth muscle cells from the muscular coat or, rarely, from muscularis
mucosae, which in the majority of cases is characterised by a clinically silent development and by an unfavorable prognosis. The considerable difficulty of obtaining a histological definition of the degree of malignancy of the leiomyosarcoma is also typical. The paper reports a clinical case and summarises its main clinical and anatomopathological aspects. In particular, the difficulties of clinical and histological diagnosis of the degree of malignancy are underlined, together with the fact that these have a considerable influence on the possibilities and results of surgical therapy and survival rates
PM fractional machines adopting bonded magnets: effect of different magnetizations on the energetic performance
No full textThe adoption of Permanent Magnets in small brushless machines for automotive applications is becoming frequent. Some research on bonded magnets is being carried on to substitute the ferrites. In the paper the parallel and radial magnetizations are considered: the different process complexity levels are analyzed and the effects on the iron losses and the energetic performances are evaluated by means of a simulation analysis and its experimental validatio

The results of a study on 848 patients with breast carcinoma having maximum diameter less than or equal to 2 cm, that underwent a surgical treatment at the Institute of Special Surgical Pathology B (1980-82) and at the Institute of Surgical Clinic I (1980-89) are presented. The study has the purpose of evaluating, by the analysis of ten years surviving curves, the effectiveness of different types of interventions: Halsted radical mastectomy (98 patients), Patey radical mastectomy (245 patients) and Madden radical mastectomy (151 patients), quadrantectomy (260 patients). The age of patients ranges from 29 years to 92 years (average 56 years). The 68.04% of all tumors have resulted invasive ductal carcinoma (NOS) the 9.08% lobular carcinoma. Of the 848 patients included in the study 698 are alive at the end of the follow-up, with a survival rate, calculated with the actuarial method, equivalent to 63.38%. Results show the survival is independent of the type of surgical treatment (71.9% for quadrantectomy; 70.7% for Halsted radical mastectomy, 68.9% for Patey radical mastectomy; 70.7% for
Madden radical mastectomy)

No full textLow-cost electrochemical impedance spectroscopy system for corrosion monitoring of metallic antiquities and works of art
No full textElectrochemical impedance spectroscopy (EIS) is recognized to be a powerful and noninvasive technique to test the integrity of protective coatings on memorials, but commercial EIS systems are rather costly though versatile devices. This paper describes a low cost and portable EIS system that is based on a compact digital signal processor (DSP) board and embeds the potentiostatic function so that it can be used without requiring an external potentiostat. The software that runs on the DSP is designed to analyze the electrochemical impedance only in a reduced frequency range in order to produce a simple corrosion alert result. The device is equipped with a digital interface and can be connected to a personal computer to carry out a complete frequency analysis and perform a more complex data processing
