No full textThis paper pays attention to the processes of increase in value of urban systems, and represents the first phase of a wider research.
The processes of increase in value of urban system are the result of a supplemented set of actions directed to create the conditions so that the different components of urban system can acquire or increase their value.
This research intends to arrive at the construction of a methodological path, to individualize strategies of increase in value of urban system, and at its application on a concrete case. For this reason, the research sets up a cognitive outline of the most significant national and international experiences about the increase in value of urban system, and individualizes different typologies of interventions that can increase the value and whole quality of the urban system.
In the light of the carried out work, the paper presents a first result of research: the reading of the most significant experiences of the increase in value of urban ambits that already have been realized or are being carried out in Italy and Europe. This paper is articulated in an introduction to the theme and a review of some cases study
Dusty-wind-clear JWST Super-early Galaxies
No full textThe JWST discovery of a number of super-early (redshift z > 10) blue galaxies requires these systems to be essentially dust free in spite of their large stellar masses. A possible explanation is that dust is evacuated by radiatively driven outflows. We test this hypothesis by deriving the Eddington ratio λ _E = L _bol / L _E , where L _bol is the bolometric luminosity produced by star formation and possible black hole accretion, for 134 galaxies at 6.5 13 Gyr ^−1 develop powerful outflows clearing the galaxy from its dust. This result is supported by ALMA dust continuum nondetections in three super-early systems
Rare lymphoid malignancies of the breast: report of two cases illustrating potential diagnostic techniques.
No full textTwo cases of lymphoid malignancy involving the breast are herein presented. Both patients were admitted with a palpable breast mass. Ultrasound demonstrated hypoechoic, ill-defined lesions of the breast in both patients; mammogram also showed spiculated breast densities. Both patients underwent core biopsy, which revealed lymphomatous cells. Total-body evaluation was also performed by computed tomography and positron emission tomography/computed tomography revealing no other fluorodeoxyglucose-avid foci in the first case and supra and subdiaphragmatic disease in the second one
