Radiation from Isolated Spectral Lines with Combined Doppler and Lorentz Broadening [PDF]

, 1953
Methods for the calculation of spectral absorption coefficients for combined Doppler and Lorentz broadening are summarized. The “curves of growth” have been extended to cover the ranges of parameters which arise in spectroscopic studies on ...

Hybrid cell lines producing monoclonal antibodies directed against Treponema [PDF]

, 1985
Continuous hybrid cell lines for producing monoclonal antibodies directed against antigens of Treponema pallidum have been developed. The hybrid cell lines were established by fusing differentiated lymphoid cells primed with antigens of Treponema ...

Recombination Rate Coefficients for KLL Di-electronic Satellite Lines of Fe XXV and Ni XXVII [PDF]

, 2008
The unified method for total electron-ion recombination is extended to study the dielectronic satellite (DES) lines. These lines, formed from radiative decay of autoionizing states, are highly sensitive temperature diagnostics of astrophysical and ...

The complex X-ray spectrum of the isolated neutron star RBS1223 [PDF]

, 2006
We present a first analysis of a deep X-ray spectrum of the isolated neutron star RBS1223 obtained with XMM-Newton. Spectral data from four new monitoring observations in 2005/2006 were combined with archival observations obtained in 2003 and 2004 to ...

Neopapillarine, an Unusual Coumarino-Alkaloid from the Root Extract of Neocryptodiscus papillaris with Cytotoxic Activity on Renal Cancer Cells

Molecules, 2020
Several simple and prenylated coumarin derivatives were isolated from the dichloromethane extract of the root of Neocryptodiscus papillaris based on moderate cytotoxic activity of the extract in COLO205, KM12 and MCF7 cancer cells.

Three New Cytotoxic ent-Kaurane Diterpenes from Isodon excisoides

Molecules, 2015
Three types of ent-kaurane diterpenoids were isolated from the aerial parts of Isodon excisoides, including three new diterpenoids, 1α,7α,14β-trihydroxy-20-acetoxy-ent-kaur-15-one (1); 1α,7α,14β,18-tetrahydroxy-20-acetoxy-ent-kaur-15-one (2); and 1α ...

A Fisher-Rao metric for paracatadioptric images of lines [PDF]

, 2012
In a central paracatadioptric imaging system a perspective camera takes an image of a scene reflected in a paraboloidal mirror. A 360° field of view is obtained, but the image is severely distorted.
