The HITRAN2016 molecular spectroscopic database
This paper describes the contents of the 2016 edition of the HITRAN molecular spectroscopic compilation. The new edition replaces the previous HITRAN edition of 2012 and its updates during the intervening years. The HITRAN molecular absorption compilation is composed of five major components: the traditional line-by-line spectroscopic parameters required for high-resolution radiative-transfer codes, infrared absorption cross-sections for molecules not yet amenable to representation in a line-by-line form, collision-induced absorption data, aerosol indices of refraction, and general tables such as partition sums that apply globally to the data. The new HITRAN is greatly extended in terms of …
The 2009 Edition of the GEISA Spectroscopic Database
The updated 2009 edition of the spectroscopic database GEISA (Gestion et Etude des Informations Spectroscopiques Atmosphériques; Management and Study of Atmospheric Spectroscopic Information) is described in this paper. GEISA is a computer-accessible system comprising three independent sub-databases devoted, respectively, to: line parameters, infrared and ultraviolet/visible absorption cross-sections, microphysical and optical properties of atmospheric aerosols. In this edition, 50 molecules are involved in the line parameters sub-database, including 111 isotopologues, for a total of 3,807,997 entries, in the spectral range from 10-6 to 35,877.031cm-1.The successful performances of the new …
Osteocondroma intra-raquideo con afectación neurológica
Se presenta el caso de un varón de 16 años con lumbalgia consecutiva a traumatismo vertebral, sin hallazgo s radiológicos, que no mejoraba con tratamient o conservador, y que a las 5 semanas desarrolló un cuadro de paraparesia e incontinencia de esfínteres indicativo de afectación del cono medular. En el estudio mielográfico se objetivó bloqueo completo a nivel de Ll. La tomografía axial mostró una imagen sugestiva de osteocondroma intraraquídeo, que s e confirmó quirúrgicamente . Dos año s tras la intervención, se logró la total recuperación neurológica. Se destaca la rareza de la lesión, la dificultad diagnóstica, y la probable etiología traumática de la tumoración. A 16-year-old man with…
