Effects of Chemotherapy in Patients with Concomitant Aortic Aneurysm and Malignant Disease
No full textBackground: The aim of the study is to present the results in a consecutive series of patients affected by aortic abdominal aneurysm and to underline the aneurysmal growth and evolution in oncological patients submitted to dedicated oncological medical therapy. Methods: Between January 2010 and June 2016 we treated in our center 19 patients for coexisting aortic aneurysms (>3 cm) and malignancy. We observed patients undergoing oncological treatment and patients who did not undergo medical treatment. We studied computed tomography (CT) scan at the time when patients were addressed at our follow-up or treatment and we analyzed retrospectively prior CT scan at 6 and 12 months. Results: Among those 19 patients, 7 patients were affected by colorectal cancer (36.8%), 6 by urinary tract cancer (31.6%), 4 by lymphoma (21%), and 2 by lung cancer (10.6%). In 8 patients who did not undergo oncological therapy, we did not observe any aortic growth; instead, in other 4 patients who underwent oncological medical therapy (3 abdominal aortic aneurysms and 1 thoracic aneurysm), we observed a mean sac growth of 2.9 cm in 6 months with 2 cases of aortic rupture treated in urgent fashion. The treatment was open surgery in 2 cases and endovascular in other cases. Conclusions: We observed that oncological drugs may play a role in aneurysm growth. Few case reports are found in the literature and more evidences are to be found. Those information may influence intention-to-treat small aneurysms in short life expectancy patients
Space and the nation: three texts on Aldo Rossi
No full textIn this paper the spatial dimensions of political practice and the historical dimensions of architectural practice are examined. The author argues that these two practices intersect when, in the life of a city and a nation, time is transformed into space. The productivity of death in this regard is explored. In developing this argument, reference is made to the works and writings of Regis Debray and Aldo Rossi, as well as events in the recent political history of South Africa

Experimental High-Frequency Parameter Identification of AC Electrical Motors
No full textIn order to predict conducted electromagnetic interference in inverter-motor drive systems, high-frequency (HF) motor models are requested and the involved parameters have to be available. In previous studies, the authors have presented an accurate HF model for induction motors and they have defined the procedures to identify the model parameters. In this paper, these results are extended to several types and sizes of industrial ac motors such as induction, synchronous reluctance (without interior permanent magnets), and brushless motors. The model parameter-identification procedure has been improved, and it is based on a least-squares data fitting applied to the measured magnitude and phase-frequency-response curves of the phase-to-ground and the phase-to-neutral impedances. The aim of this paper is to provide quick indications to select the suitable values of the HF model parameters, with reference to the size and type of the ac motor, to evaluate the HF voltage and current components in inverted-fed ac motor system

Woodworking for Wildlife - Aldo Leopold Bench
No full textAldo Leopold is an internationally recognized figure in wildlife conservation and pioneering author and philosopher on environmental ethics and land stewardship. Born and raised in southeastern Iowa on the bluffs of the Mississippi River in Burlington, Leopold’s land ethic was born from hundreds of hours of careful observation outdoors in Iowa, Wisconsin, the American southwest, and other natural landscapes.</p
Agli italiani piace la trasparenza amministrativa?
No full textStarting from the book by Enrico Carloni, Il paradigma trasparenza, the Author examines some profiles related to the relationship between citizens and public power and administrative transparency. According to the Author, for various reasons, including contextual and organizational ones, it is still necessary to work on the quality of transparency. The transparency paradigm represents a legal goal of civilization, to be
protected and defended, but still to be maintained and relaunched
