KINEMATICS OF TilE ION TAIL OF COMET P/SWIFT-TUTTLE
We have obtained long-slit high resolution spectra of the H20+ 6199 A complex in the near tail of comet P/Swift-Tuttle. The observations were made using the Hamilton echelle spectrometer fed by the Lick Observatory 0.6 m coude auxiliary telescope. For most of our observations, the spectral slit was aligned along the Sun-tail axis and the cometary nucleus was placed at one end of the slit, givin...
متن کاملASTRONOMY AND ASTROPHYSICS H 2 O + , CO + , and dust in Comet P / Swift - Tuttle ?
Comet P/Swift-Tuttle was observed in the light of H2O, CO+ and continuum with the 2-m telescope of the Bulgarian National Astronomical Observatory (BNAO) on Nov. 25, 1992. We present column density maps of the H2O and CO+ ions and a map of the product of filling factor, geometrical albedo, and phase function. The H2O ions are more concentrated toward the nucleus than CO+. The ion distributions ...

Historically, since the metabolism of administered peptide/protein drugs (“biotherapeutics”) has been expected to undergo predictable pathways similar to endogenous proteins, comprehensive biotherapeutic metabolism studies have not been widely reported in the literature. However, since biotherapeutics have rapidly evolved into an impressive array of eclectic modalities, there has been a shift t...

This paper introduces the XTR public key system. XTR is based on a new method to represent elements of a subgroup of a multiplicative group of a finite field. Application of XTR in cryptographic protocols leads to substantial savings both in communication and computational overhead without compromising security.
متن کاملSpectroscopic SWIFT
INTRODUCTION Often the ability to obtain chemical-shift information is needed and advantageous in MRI. In addition to providing chemical information, the acquired spectral dimension can also be used to reduce image blur resulting from frequency shifts of all types. This work describes a new 3D and 4D spectroscopic technique involving an intrinsic frequency dimension. The method is based on an o...
