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 ...

Atenolol is a b-blocker widely used in the treatment of hypertension. Atenolol is cleared predominantly by the kidney by both glomerular filtration and active secretion, but the molecular mechanisms involved in its renal secretion are unclear. Using a panel of human embryonic kidney cell lines stably expressing human organic cation transporter (hOCT) 1–3, human organic anion transporter (hOAT) ...
متن کاملAlexander Fleming, 1881-1955
Alexander Fleming (18811955) After Louis Pasteur's and Robert Koch's publications on the germ theory of disease, doctors developed a better understanding of the cause of infection. However, methods of treatment were still limited to vaccinations and anti-toxins. Joseph Lister's carbolic spray worked with some success during operations, but was not suitable for everyday use. The question was, ho...
