Interstellar processes: Ortho/para conversion, radiative association, and dissociative recombination
The study of the ortho-to-para ratio of assorted gas-phase interstellar molecules such as H2, H2O, NH3, and H2O+ has gained interest in recent years, based partially on new spectral observations of light hydrides by the Herschel Space Observatory ...

CLOUD STRUCTURE OF INTERSTELLAR MATTER. OBSERVATIONAL PARAMETERS
Parameters of 7600 HI clouds were determined on the base of HI RATAN-600 Survey in the second and third quadrants of galactic longitudes. The spectra of cloud linear diameters, HI densities and masses are obtained first for such huge population of clouds.

Interstellar cloud collisions [PDF]
On decrit les resultats d'une simulation numerique en 3 dimensions de nuages interstellaires isothermes en l'absence de champs magnetiques. Les collisions, en general, ne donnent pas naissance a un ou plusieurs nuages.

PECULIARITIES OF MIXING METALS IN INTERGALACTIC AND INTERSTELLAR MEDIA
We review the current status of the problem of metal mixing in the intergalactic and interstellar media. We give simple arguments for inefficiency of mixing metals because of a saturation of hydrodynamic (Rayleigh-Taylor and Kelvin-Helmholz ...

Cloud Services Brokerage : a survey and research roadmap [PDF]
A Cloud Services Brokerage (CSB) acts as an intermediary between cloud service providers (e.g., Amazon and Google) and cloud service end users, providing a number of value adding services. CSBs as a research topic are in there infancy.

Molecular cloud structure in the star-forming region W43 [PDF]
In the struggle toward an understanding of the process of star formation it is one of the most important tasks to study the initial properties of the cold and dense interstellar medium. Stars are known to form in dense molecular clouds, but it is not yet

Discovery of the Elusive Carbonic Acid (HOCOOH) in Space
A quarter century after the detection of the last interstellar carboxylic acid, acetic acid (CH _3 COOH), we report the discovery of a new one, the cis-trans form of carbonic acid (HOCOOH), toward the Galactic center molecular cloud G+0.693–0.027. HOCOOH

Diffuse Interstellar Clouds [PDF]
AbstractDiffuse clouds are interstellar objects through which starlight is not greatly extinguished. As a result, many studies rely on ultraviolet and visible measurements. The focus of this review is on spectroscopic work involving atomic and molecular lines. From these measurements, the physical and chemical makeup of the clouds is derived.
