Photoevaporation of Clumps in Photodissociation Regions
We present the results of an investigation of the effects of Far Ultraviolet (FUV) radiation (6.0eV < hν < 13.6eV) from hot early type OB stars on clumps in star-forming molecular clouds. Clumps in FUV-illuminated regions (or pho-todissociation regions or PDRs) undergo external heating and photodissociation as they are exposed to the FUV field, resulting in a loss of cold, molecular clump mass ...
متن کاملLowering Inferred Cluster Magnetic Field Strengths - the Radio Galaxy Contributions
We present a detailed examination of the relationship between the magnetic field structures and the variations in Faraday Rotation across PKS1246−410, a radio source in the Centaurus cluster of galaxies, using data from Taylor, Fabian and Allen. We find a significant relationship between the intrinsic position angle of the polarization and the local amount of Faraday Rotation. The most plausibl...
متن کاملNon-equilibrium Photodissociation Regions: Ionization-dissociation Fronts
We discuss the theory of coupled ionization{dissociation fronts produced when molecular clouds are exposed to < 1110 A radiation from hot stars. A steady, composite structure is developed, which generally includes an ionized outtow away from the cloud, an ionization front, a layer of photodissociated gas, a photodissociation front, and a shock wave preceding the photodissociation front. We show...
متن کاملComparison of magnetic properties of MRI contrast media solutions at different magnetic field strengths.
RATIONALE AND OBJECTIVES To characterize and compare commercially available contrast media (CM) for magnetic resonance imaging (MRI) in terms of their relaxivity at magnetic field strengths ranging from 0.47 T to 4.7 T at physiological temperatures in water and in plasma. Relaxivities also were quantified in whole blood at 1.5 T. METHODS Relaxivities of MRI-CM were determined by nuclear magne...
متن کاملDesignated magnetic field design for magnetic drug guidance in BNCT
In this paper, a local magnetic field was designed and simulated using a Helmholtz coil along with a ferromagnetic core with an appropriate geometric Structure to concentrate a magnetic flux. This field can be used for magnetic guiding of Boron-borne drugs in BNCT.
