Bilateral stress fracture of the tibia diagnosed by ultrasound. A case report

Author(s) : Khy, V. , Wyssa, B. , Bianchi, S.
Description : We report the case of a 35 years old patient presenting with bilateral pain in the medial aspect of both knees. Ultrasound examination revealed hyperechoic appearance of the subcutaneous tissue and periarticular soft tissue bilateral. Color Doppler studies showed significant vascular signals at the ...

Strain rate effects on mechanical properties in tension of aluminium alloys used in armour applications

Author(s) : Cadoni E. , Dotta M. , Forni D. , Bianchi S. , Kaufmann H.
Description : The mechanical properties in tension of two aluminium alloys (AA5059-H131 and AA7039-T651) used in armour applications were determined from tests carried out over a wide range of strain-rates on round specimens. The experimental research was developed in the DynaMat laboratory of the University of ...

Monte Carlo Predictions of Far-Infrared Emission from Spiral Galaxies

Author(s) : Bianchi, S. , Davies, J. I. , Alton, P. B.
Description : We present simulations of Far Infrared (FIR) emission by dust in spiral galaxies, based on the Monte Carlo radiative transfer code of Bianchi, Ferrara & Giovanardi (1996). The radiative transfer is carried out at several wavelength in the Ultraviolet, optical and Near Infrared, to cover the range ...

Lyman Continuum Escape from Inhomogeneous ISM

Author(s) : Ciardi, B. , Bianchi, S. , Ferrara, A.
Description : We have studied the effects of gas density inhomogeneities on the escape of ionising Lyman continuum (Lyc) photons from Milky Way-type galaxies via 3D numerical simulations using the Monte Carlo radiative transfer code CRASH (Ciardi et al. 2001). To this aim a comparison between a smooth Gaussian ...

The reprocessing features in the X-ray spectrum of the NELG MCG-5-23-16

Author(s) : Balestra, I. , Bianchi, S. , Matt, G.
Description : We present results from the spectral analysis of the Seyfert 1.9 galaxy MCG-5-23-16, based on ASCA, BeppoSAX, Chandra and XMM-Newton observations. The spectrum of this object shows a complex iron Kalpha emission line, which is best modeled by a superposition of a narrow and a broad (possibly relat...

Statistics of relativistically broadened Fe K-alpha lines in AGN

Author(s) : Guainazzi, M. , Bianchi, S. , Dovciak, M.
Description : We present preliminary results on the properties of relativistically broadened Fe K-alpha lines in a collection of more then 100 Active Galactic Nuclei (AGN) observed by the XMM-Newton EPIC-pn camera. Our main conclusions can be summarized as follows: a) we detect broad lines in about 25% of the s...

An Atlas of Monte Carlo Models of Dust Extinction in Galaxies for Cosmological Applications

Author(s) : Ferrara, A. , Bianchi, S. , Cimatti, A. , Giovanardi, C.
Description : We present an extensive study of the radiative transfer in dusty galaxies based on Monte Carlo simulations. The main output of these simulations are the attenuation curves ${\cal A}_\lambda$ (i.e. the ratio between the observed, dust extinguished, total intensity to the intrinsic unextinguished on...

On the peculiar properties of the narrow-line quasar PG 1543+489

Author(s) : Vignali, C. , Piconcelli, E. , Bianchi, S. , Miniutti, G.
Description : We present the analysis of four XMM-Newton observations of the narrow-line quasar PG 1543+489 at z=0.400 carried out over a rest-frame time-scale of about three years. The X-ray spectrum is characterized by a broad, relativistic iron K_alpha emission line and a steep photon index, which can be bot...

Theory of Radio Propagation in Inhomogeneous Media (The Eikonal Method)

Author(s) : Bianchi, S. , Sciacca, U. , Settimi, A.
Description : The Istituto Nazionale di Geofisica e Vulcanologia has been involved since its foundation in the forecast of the conditions in which a radio link that makes use of propagation by means of ionospheric wave takes place. In the last times it gained interest also the precise forecast of the trajectory...

Chandra monitoring of UGC 4203: the structure of the X-ray absorber

Author(s) : Risaliti, G. , Elvis, M. , Bianchi, S. , Matt, G.
Description : We present a Chandra monitoring campaign of the highly variable Seyfert galaxy UGC 4203 (the "Phoenix Galaxy") which revealed variations in the X-ray absorbing column density on time scales of two weeks. This is the third, clear case, after NGC 1365 and NGC 7582, of dramatic N_H variability on sho...
