La Fiera e la città
No full textCatalogo di una mostra che scaturita da una ricerca che, avendo ad obiettivo la messa a fuoco del rapporto fra la città ed il suo polo espositivo, è divenuta occasione per una riconsiderazione della storia urbanistica ed architettonica di Bologna fra l’Unità e i giorni nostri; ciò anche alla luce dei documenti dimenticati o inediti che sono stati riportati alla luce e che hanno consentito di comporre alcuni tasselli mancanti
Polynomial adaptivity in LES: Application to compressibility effects investigation on bluff bodies
No full textThe use of a Discontinuous Galerkin framework to perform a compressible Large Eddy Simulation is an effective and accurate way to simulate complex turbulent flows. However, since the turbulent scales size is not known a priori, assumptions during the grid generation must be made. With the aim of reducing the influence of such assumptions, lowering the computational effort required to perform the LES and moving towards the adaptive LES postulated by Pope, New J Phys, 6(1):35, 2004, [5], we introduced a polynomial adaptive framework in Tugnoli, J Comput Phys, 349:33–58, 2017, [7]. In the present work we employ the aforementioned procedure to assess the effects of a varying Mach number in a flow around a square section cylinder, a configuration of interest for example for flame holders in combustors. Since most of the reference data on this kind of flows is obtained by incompressible computations (e.g. Rodi et al, J Fluids Eng, 119(2):248–262, 1997, [6]) and experiments (e.g. Lyn et al, J Fluid Mech, 304:285–319, 1995, [4]) the aim is to assess what are the effects of slightly higher Mach numbers in such flows, and what is the error involved into comparing compressible simulations results with incompressible reference data
Current status of Magnetic Resonance Spectroscopy in the study of kidney tumors.
No full textNuclear Magnetic Resonance Spectroscopy (MRS) in the study of human renal neoplastic pathologies has two types of applications:
- The first application is aimed at the clinical use of in vivo spectroscopy as it is commonly employed for other organs, such as brain, prostate and breast (diagnosis, treatment and control, prognosis);
- The second one is due to its ability to identify tissue metabolites. This specificity allows the control of molecular changes, i.e. altered metabolic processes, taking place in renal neoplastic tissues. Thus, it makes a contribution, at molecular level, to the knowledge of tumor biochemistry.
From this point of view, MRS is aimed at either clinical or basic research. For these reasons the chapter is organized according to the research advancements both at biochemical and clinical level
Adjusting the course: Constancy and flexibility in the construction of analytic space
No full textThe author reflects on the setting and the problematic question of the relationship between constant elements that define the frame of the clinical context and the variables that actively intervene in the analytic process. Every patient tends to «be in the setting» according to the determining factors of his mental structure and his own relational patterns, and it is necessary to modulate the construction and maintenance of the analytic space, taking into account the characteristics of both members of the couple, in the context of transformative transactions between the analyst’s setting and that of the patient, in a negotiation (explicit and implicit) that brings into play the intrapsychic frameworks and relational configurations of both. A clinical sequence illustrates how, in circumstances particularly critical to the relationship, detailed and thoughtful interventions to adjust elements of the setting, actions charged with symbolic and relational meaning, can impact the transformative developments of the analysis in a meaningful way
