Very light magnetized jets on large scales - I. Evolution and magnetic fields
(2009-12-21)
Magnetic fields, which are undoubtedly present in extragalactic jets and responsible for the observed synchrotron radiation, can affect the morphology and dynamics of the jets and their interaction with the ambient cluster ...
The role of Type Ia Supernovae in chemical evolution 1 : Lifetime of Type Ia Supernovae and metallicity effect
(2009-12-20)
We construct a new model of Type Ia Supernovae (SNe Ia), based on the single degenerate scenario, taking account of the metallicity dependences of white dwarf (WD) wind and the mass-stripping effect on the binary companion ...
Transplantation of organic surface horizons of boreal soils into warmer regions alters microbiology but not the temperature sensitivity of decomposition
(2009-12-16)
Changes in soil carbon, the largest terrestrial carbon pool, are critical for the global carbon cycle, atmospheric CO2 levels and climate. Climate warming is predicted to be most pronounced in the northern regions and ...
Leaf litter decomposition-Estimates of global variability based on Yasso07 model
(2009-12-10)
Litter decomposition is an important process in the global carbon cycle. It accounts for most of the heterotrophic soil respiration and results in formation of more stable soil organic carbon (SOC) which is the largest ...
Aryldiketo acids have antibacterial activity against MDR Staphylococcus aureus strains : Structural insights based on similarity and molecular interaction fields
(2009-12-07)
(Chemical Equation Presented) Similar structure=similar activity? The effect of substituents on the antibacterial activity of aryldiketo acids has been rationalised by molecular interaction fields and similarity studies ...
The interactions of winds from massive young stellar objects : X-ray emission, dynamics and cavity evolution
(2009-12-01)
Two-dimensional axis-symmetric hydrodynamical simulations are presented which explore the interaction of stellar and disc winds with surrounding infalling cloud material. The star and its accompanying disc blow winds inside ...
Burst-polling based dynamic bandwidth allocation using adaptive minimum guaranteed bandwidth for EPONs
(2009-12)
The enhanced burst-polling dynamic bandwidth allocation (EBDBA) method is proposed to support broadband access networks based on quality of service for Ethernet passive optical networks (EPONs). EBDBA adaptively increases ...
Measurements of the cosmological evolution of magnetic fields with the Square Kilometre Array
(2009-12-01)
We investigate the potential of the Square Kilometre Array (SKA) for measuring the magnetic fields in clusters of galaxies via Faraday rotation of background polarized sources. The populations of clusters and radio sources ...
Manuel Ocana likes it on the rocks.
(2009-12)
A brief report on a new housing complex of 53 apartments in the town of Ocana in the province of Toledo, designed by architect Manuel Ocana and taking its inspiration from the 'Hanging Houses' of the walled town of Cuenca, ...
