Experimental correlation of forced convection heat transfer from a NACA airfoil
No full textThe results of an experimental investigation of the heat transfer coefficients for forced convection from a NACA-63421 airfoil are presented. Wind tunnel measurements of convection coefficients are obtained for air flow temperatures from −30 to 20 °C. The experimental data is correlated with respect to the Nusselt and Reynolds numbers. Conduction within the airfoil balances heat transfer by convection from the airfoil surface in steady-state conditions. Both average and spatial variations of the heat transfer coefficients are non-dimensionalized through modifications of a classical Hilpert correlation for cylinders in crossflow. It is shown that the functional form of the Hilpert correlation can effectively accommodate measured data for the NACA airfoil over a range of Reynolds numbers. An uncertainty analysis is performed to yield a 7.34% measurement uncertainty for experimental data correlated with the Nusselt number.Natural Sciences and Research Council of Canada (NSERC)Manitoba HydroCanada Foundation for Innovation (CFI

Dynamic resonance and social reciprocity in language change : The case of Good morrow
No full textEntrenchment (i.e. Langacker, 1987) does not necessarily lead to predictable behaviour. This study aims at complementing the usage-based model of language change by oper- ationalising the role of dialogic creativity as a mechanism that can be in competition with conventionalization and grammaticalization. We provide a distinctive collexeme analysis (i.e. Hilpert, 2006) focussing on the constructionalization of the dialogic pair [A: good morrow B e B: (good) morrow (A)] from the 15th up to the 18th century. After reaching the highest degree of entrenchment and automatisation, the dialogic pair will show an increasing tendency to be creatively re-modelled with ad-hoc meanings during online exchanges by means of dynamic resonance (Du Bois, 2014) and non-reciprocal behaviour. We define this creative process of large-scale alteration as entrenchment inhibition. From our data it will emerge that entrenchment inhibition is triggered by spontaneous attempts of producing a creative ‘surplus’ over the expected social reciprocity (Gouldner, 1960) of conventionalized exchanges. This tendency will be shown to be driven by marked attempts of polite and impolite behaviour

NEGATIVE ION CHEMICAL IONIZATION MASS SPECTROMETRY OF POLYCYCLIC AROMATIC HYDROCARBONS
No full textThe negative ion chemical ionization (NICI) mass spectrometry of thirty-nine polycyclic aromatic hydrocarbons (PAH) was investigated. The methane NICI mass spectra of PAH are dominated by the molecular anion for species which show high NICI sensitivity, and by the molecular anion plus adduct ions for insensitive species. PAH adducts are formed under NICI conditions between the molecular PAH species in the gas phase and radical species present in the methane plasma. The alkyl-PAH adduct species is subsequently ionized by resonance capture of a low energy thermal electron. NICI spectra acquired using methane and deuteromethane as the reagent gases were used to elucidate two reaction schemes leading to the formation of the observed adduct ions. The absolute sensitivities for individual PAH varied over more than three orders of magnitude under methane NICI conditions, and the sensitivity and selectivity of detection for isomeric PAH were found to depend on the pressure and temperature in the ion source of the mass spectrometer. The selectivity of detection observed for parent PAH species was also observed for their alkylated homologues. The selectivity of NICI for isomeric PAH was used for the qualitative and quantitative determination of trace levels of PAH and alkylated-PAH in samples of a petroleum crude oil, diesel particulate matter, and urban air particulate matter.Source: Dissertation Abstracts International, Volume: 47-11, Section: B, page: 4488.Ph.D. American University 1986.Englis
