Molecular Line Observations of Isolated Cores

2014
We 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.

Microfabricated transmission-line transformers with DC isolation

2014 United States National Committee of URSI National Radio Science Meeting (USNC-URSI NRSM), 2014
A transmission line transformer (TLT) is a device that transforms a circuit impedance and is implemented with interconnected transmission lines. While traditional TLTs, operating at UHF and low microwave frequencies, are constructed from pairs of coaxial lines wound around ferrite cores, various compact implementations at higher frequency without ...

The Isolation and Detection of Atomic Resonance Lines

Applied Optics, 1968
Since the spectrum of the resonance radiation from an atomic vapor consists only of those spectral lines that are absorbed by the vapor, resonance lamps can serve as monochromators for isolating these lines. The atomic vapor is produced by cathodic sputtering in a rare gas discharge or, in the case of elements with high vapor pressure at low ...

Isolating points by lines in the plane

Journal of Geometry, 1998
The authors consider the problems of finding a minimal arrangement of straight lines, or of pseudolines (homeomorphic images of lines), that isolates every point of a specified finite set. Results are obtained for both problems. As can be imagined, the straight-line version of the problem is difficult, and the exact number of lines needed depends on ...

Isolation and Characterization of a Stromal Cell Line

1992
Considerable progress in identifying cells and cytokines that regulate primary B cell differentiation has been made in the last few years, and it is now possible to present a model that identifies the stages at which various developmental signals act on B lineage cells.

Lepidopteran Insect Cell Line Isolation from Insect Tissue

2007
This chapter describes procedures for initiating new cell lines from lepidopteran larval tissues and embryos. The internal morphology is described along with methods for treating excised tissues and the primary cultures. Advice on culture medium and the tissues that will provide the best chance for new cell lines is discussed.
