We report the detection of linear polarization from Sgr A⋆ at 750, 850, 1350 and 2000μm which confirms the contribution of synchrotron radiation. From the lack of polarization at longer wavelengths it appears to arise in the millimetre/sub-millimetre excess. There are large position angle changes between the millimetre and sub-millimetre results and these are discussed in terms of a polarized d...

The aim of the present study is to determine the best size and type of corneal graft (lamellar or penetrating, as judged by the incidence of postoperative complications) for use in cases of central or peripheral leucoma adherens measuring 4-5 mm. or less. Penetrating grafts smaller than 4 mm. rarely remain transparent and those above 7 mm. also often become opaque and may be complicated by glau...

We present the results of sub-mm, mm (850 μm, 450 μm and 1250 μm) and radio (1.4 and 4.8 GHz) continuum observations of a sample of 27 K-selected Extremely Red Objects, or EROs, (14 of which form a complete sample with K < 20 and I − K > 5) aimed at detecting dusty starbursts, deriving the fraction of UltraLuminous Infrared Galaxies (ULIGs) in ERO samples, and constraining their redshifts using...

BACKGROUND AND PURPOSE Multidetector CT imaging of the cervical spine performed with submillimeter collimation allows for the production of excellent quality multiplanar reformations and reconstructed axial images at any chosen section thickness. Currently there is no consensus on what images need to be reviewed for accurate diagnosis of cervical spine fractures. Our study assesses whether 1-mm...

OLIMPO is a 2.6 meter on-axis millimeter-wave Cassegrain telescope, mounted on an attitude controlled stratospheric balloon payload. This telescope is designed to be flown with a > 10 days Long Duration CircumPolar flight. The system contains 4 arrays of bolometers in the wavelength bands centered at 150, 220, 350, 600 GHz. The instrument will be diffraction limited at 150 GHz (3.5 arcminutes F...

We present starburst models for far-infrared/sub-millimeter/millimeter (FIR/sub-mm/mm) line emission of molecular and atomic gas in an evolving starburst region, which is treated as an ensemble of non-interacting hot bubbles which drive spherical shells of swept-up gas into a surrounding uniform gas medium. These bubbles and shells are driven by stellar winds and supernovae within massive star ...

10 Nanocrystalline Mg87Ni3Al3Mm7 hydrides were produced by reactive mechanical milling (RMM) under hydrogen atmosphere. Milling first under argon, and then under hydrogen atmosphere was also carried out in order to study the effect of the gas atmosphere on the microstructure of the products of milling as well as on their hydriding properties. In both cases, the main product of the milling proce...
