We have obtained the first continuous disk averaged spectrum of Mars from 450 to 1550 Ghz using the Herschel-SPIRE Fourier-transform spectrometer. The spectrum was obtained at a constant resolution of 1.4 GHz across the whole band. The flux from the planet is such that the instrument was operated in “bright source” mode to prevent saturation of the detectors. This was the first successful use of this mode and in this work we describe the method used for observing Mars together with a detailed discussion of the data reduction techniques required to calibrate the spectrum. We discuss the calibration accuracy obtained and describe the first comparison with surface and atmospheric models. In addition to a direct photometric measurement of the planet the spectrum contains the characteristic transitions of [SUP]12[/SUP]CO from J 5-4 to J 13-12 as well as numerous H[SUB]2[/SUB]O transitions. Together these allow the comparison to global atmospheric models allowing the mean mixing ratios of water and [SUP]12[/SUP]CO to be investigated. We find that it is possible to match the observed depth of the absorption features in the spectrum with a fixed water mixing ratio of 1×10[SUP]-4[/SUP] and a [SUP]12[/SUP]CO mixing ratio of 9×10[SUP]-4[/SUP].

We report on an initial analysis of Herschel/HIFI observations of hydrogen chloride (HCl), hydrogen peroxide (H[SUB]2[/SUB]O[SUB]2[/SUB]), and molecular oxygen (O[SUB]2[/SUB]) in the Martian atmosphere performed on 13 and 16 April 2010 (L[SUB]s[/SUB] ~ 77°). We derived a constant volume mixing ratio of 1400 ± 120 ppm for O[SUB]2[/SUB] and determined upper limits of 200 ppt for HCl and 2 ppb for H[SUB]2[/SUB]O[SUB]2[/SUB]. Radiative transfer model calculations indicate that the vertical profile of O[SUB]2[/SUB] may not be constant. Photochemical models determine the lowest values of H[SUB]2[/SUB]O[SUB]2[/SUB] to be around L[SUB]s[/SUB] ~ 75° but overestimate the volume mixing ratio compared to our measurements.

The gender system of the northern variety of Dutch has a long and well-known history of development. These developments seemingly have led to a divergence between the northern and the southern gender system, the latter one being a more conservative system, retaining the original three genders. Regarding pronominal gender, recent studies have indicated that the northern varieties make use of some semantic properties of the referent, in order to choose the appropriate pronoun. In the southern varieties there is still syntactic agreement: the choice of the pronoun is based upon the grammatical gender of the noun, rather than on the conceptual properties of its referent. This article investigates the extent to which southern speakers use grammatical gender, in order to clarify the current situation of the pronominal gender system in southern Dutch. As the results will show, the southern pronominal gender system has started developing to a semantic system, so that the distance between the gender systems of both varieties of Dutch will decrease.

A binder is prepared by reacting isocyanate-functional compound(s) containing uretdione groups; compounds that contain isocyanate-reactive groups and contain groups that react with ethylenically unsaturated compounds; saturated, hydroxyl-containing compound(s); and a catalyst containing ammonium salts or phosphonium salts of aliphatic or cycloaliphatic carboxylic acids. Preparation of a binder containing allophanate groups, groups that react with ethylenically unsaturated compounds with polymerization on exposure to actinic radiation (radiation-curing groups), and optionally isocyanate (NCO)-reactive groups, which comprises reacting at 130[deg]C NCO-functional compound(s) containing uretdione groups; compounds that contain isocyanate-reactive groups and contain groups that react with ethylenically unsaturated compounds with polymerization on exposure to actinic radiation (radiation-curing groups); saturated, hydroxyl-containing compound(s), at least one of these compounds having an OH functionality of 2; and a catalyst containing one or more ammonium salts or phosphonium salts of aliphatic or cycloaliphatic carboxylic acids, the reaction hydroxyl-containing compounds taking place at least proportionally with the formation of allophanate groups. An independent claim is also included for a coating composition comprising: (1) binders; (2) optionally polyisocyanate(s) which contain free or blocked isocyanate groups and optionally contain groups which react with ethylenically unsaturated compounds with polymerization on exposure to actinic radiation; (3) optionally compounds other than the polyisocyanate(s) which contain groups which react with ethylenically unsaturated compounds with polymerization on exposure to actinic radiation and optionally contain NCO-reactive groups; (4) optionally isocyanate-reactive compound(s) which are free from groups which react with ethylenically unsaturated compounds with polymerization on exposure to actinic radiation; and (5) initiators.
