Infrared study of hydrogen bonding of methanol in the liquid phase

The V(_s)(OH) band of methanol in binary system has been studied by using infrared spectroscopy, over the whole concentration range between 0.01 - 0.7 methanol mole fraction. The aim of this study is to analyze this band which is very complicated, due to overlapping between its band components, and to correlate the results to the possible underlying equilibrium. Also the change in the V(_s)(OE) band shape across the concentration range, imposed the necessity of studying the V(-s)(OH) of methanol in non-polar solvent at a very low concentrations (0.0049 to 0.0246 mol/dm(^3)) in order to identify the existing varieties of methanol hydrogen bonded species, as well as the monomer. A study of the V(_s)(OH) for methanol in the ternary system (CH(_3)OH/CH(_3)CN/CCL(_4)) was undertaken, in order to defferentiate the band components of the hydrogen bonded complexes formed from methanol and acetonitrile molecules, from the hydrogen bonded methanol aggregates. This study was carried out in a concentration range of 0.0044 to 0.0177 mol/dm(^3). For the binary system, because of the complexes of the bands, a band fitting programs were used as a means of estimating the number of bands present, their positions and band shapes of each component. As a result, this study has shown that the I.R. data for methanol in acetonitrile band fitting model contained: monomer, dimer, 1:1 and 2:1 complexes, trimer, tetramer and pentamer species

A survey on author profiling, deception, and irony detection for the Arabic language

To infer a user's gender, age, native language, language variety, or even when the user lies, simply by analyzing her texts, opens a wide range of possibilities from the point of view of security. In this paper, we review the state of the art about some of the main author profiling problems, as well as deception and irony detection, especially focusing on the Arabic language.Qatar National Research Fund, Grant/Award Number: NPRP 9-175-1-033Rosso, P.; Rangel-Pardo, FM.; Hernandez-Farias, DI.; Cagnina, L.; Zaghouani, W.; Charfi, A.

Toward a Typology of Arabic Dialects: The Role of Final Consonantality

The salient constraint on Arabic stems is final consonantality which stipulates that the right edge of a stem must be marked by a consonant. In this paper, I examine the role of final consonantality as an extended prosodic constraint operating on syllables and moras, functioning as a parameter differentiating the main two dialectal types, onset and coda dialects. The effect of final consonantality is observed not only in specifying the site of epenthesis, but also in determining the distribution of prosodic rules such as gemination, degemination, and syncope as well as predicting the quality of the epenthetic vowel. The hypothesis is that extending final consonantality to the phonological component of the grammar in coda dialects is motivated by the desire to ensure uniformity between edges of prosodic and morphological constituents

Perspectives on Arabic Linguistics XXIV-XXV Papers from the annual symposia on Arabic Linguistics. Texas, 2010 and Arizona, 2011

Recent studies of sluicing as an elliptical construction are divided with respect to how the bare wh-word in the sluicing clause (i.e. wh-sluice) manifests its expected grammatical properties on the one hand, and receives its semantic interpretation on the other hand. In this paper, I investigate Emirati Arabic (ea) sluicing and conclude that ea sluicing should be analyzed as tp-deletion from an underlying wh-construction, at the level of pf. This supports the pf-deletion approach (Ross 1969, Merchant 2001) and argues against the lf-copying approach (Chung, Ladusaw and McCloskey 1995, 2006, Chung 2005) to sluicing. Moreover, I demonstrate that the ea sluicing source is predetermined by the type of wh-construction in ea. ea allows two types of wh-constructions, namely wh-fronting and wh-clefts. Both wh-strategies, while morphosyntactically distinct, are fully attested in the formation of sluicing. This paper also claims that the typology of wh-constructions has a direct impact on the typology of sluicing.Perspectives on Arabic Linguistics XXIV-XXV -- Editorial page -- Title page -- LCC data -- Table of contents -- Acknowledgement -- Introduction -- Part I.
