Putaud,Yves Balkanski,Sandro Fuzzi,J. Horth,Geert K. Moortgat,R. Winterhalter,Cathrine Lund Myhre,Kostas Tsigaridis,Elisabetta Vignati,Euripides G. Stephanou,J. Wilson +21 more
TL;DR: In this article, the authors reviewed existing knowledge with regard to organic aerosol (OA) of importance for global climate modelling and defined critical gaps needed to reduce the involved uncertainties, and synthesized the information to provide a continuous analysis of the flow from the emitted material to the atmosphere up to the point of the climate impact of the produced organic aerosols.

TL;DR: In this paper, the authors determined the baseline rate of drug resistance in 2208 therapy-naive patients recently and chronically infected with HIV-1 from 19 European countries during 1996-2002.
Journal ArticleDOI
Global warming potentials and radiative efficiencies of halocarbons and related compounds: a comprehensive review
Øivind Hodnebrog,M. Etminan,Jan S. Fuglestvedt,George Marston,Gunnar Myhre,Claus J. Nielsen,Keith P. Shine,Timothy J. Wallington +7 more
TL;DR: The most comprehensive review of the radiative efficiencies and global warming potentials of halogenated compounds performed to date can be found in this article, where the authors provide a comprehensive and self-consistent set of new calculations of radiative efficiency for these compounds, mostly employing atmospheric lifetimes taken from the available literature.

Journal ArticleDOI
Molecular structure and internal motion of formamide from microwave spectrum
TL;DR: In this paper, the molecular structure of formamide has been determined by observing the microwave spectra of the 13 C and 18 O species of NH 2 CHO and ND 2 CHO, assuming the planarity of the molecule.
