Microstrip Ferrite Coupled Line Isolators
2006 International Conference on Microwaves, Radar & Wireless Communications, 2006The double isolators using sections of ferrite coupled microstrip lines are demonstrated in a layered and planar approaches. The configurations are investigated both theoretically and experimentally at the frequency range 8-15 GHz. The better performances are observed for planar configuration that reports reflection losses -15 dB, isolation better than

Isolation of amniotic stem cell lines with potential for therapy
Nature Biotechnology, 2007Stem cells capable of differentiating to multiple lineages may be valuable for therapy. We report the isolation of human and rodent amniotic fluid-derived stem (AFS) cells that express embryonic and adult stem cell markers. Undifferentiated AFS cells expand extensively without feeders, double in 36 h and are not tumorigenic.

Isolated vortex line in an antiferromagnetic superconductor
Journal of Magnetism and Magnetic Materials, 1980Abstract The Ginzburg-Landau theory and micromagnetic theory of antiferromagnetism are applied to study a magnetic structure of isolated flux line in an antiferromagnetic superconductor of type II. The structure consists of three coaxial domains in which paramagnetic, spin-flop and antiferromagnetic phases coexist with superconductivity.

Molecular Line Observations of Isolated Cores
2014We have observed a number of isolated, small molecular clouds in the12CO,13CO and C18O molecular lines using the 22-m Mopra telescope. We perform an LTE analysis to find optical depths, column densities and observed masses of each of the cores. A virial analysis suggests that all the cores are consistent with being in virial equilibrium.

Isolation and Characterisation of Mutant Cell Lines
1994It is perhaps dangerous to try to pinpoint the nascence of efforts at selection or isolation of modified phenotypes in vitro. Rather, awareness of the genetic potential of tissue culture dawned as researchers became conscious of the nature and scope of these cultures from numerous fundamental studies throughout the 1950s and 1960s.
