1,1′-[(2,3,5,6-Tetramethyl-1,4-phenylene)bis(methylene)]dipiperidine
2018
The asymmetric unit of the title compound, C22H36N2, comprises one half-molecule, the other half being generated by a center of inversion. The piperidine ring adopts a chair conformation, with the exocyclic N—C bond in an equatorial orientation. A short intramolecular C—H...N hydrogen bond occurs and forms an S(6) motif. No directional interactions beyond van der Waals contacts are observed between the molecules, which form a wave-like supramolecular architecture.
Crystal structure of (E)-2-(tert-butylamino)-4-(tert-butylimino)naphthalen-1(4H)-one
2018
The title compound is the first example of a naphthoquinone imine derivative crystallizing in the 4-imine/2-amine tautomeric form having bulky tert-butyl substituents at the N atoms.
Crystal structure of 4-(4-meth-oxy-phen-yl)-4',4'-dimethyl-3-p-tolyl-3',4'-di-hydro-1'H,3H-spiro-[isoxazole-5,2'-naphthalen]-1'-one.
2015
In the title compound, C28H27NO3, the cyclohexanone and isoxazole rings have envelope conformations, with the methylene and spiro C atoms as the flaps, respectively. The mean plane of the isoxazole ring is inclined slightly to thep-tolyl ring, making a dihedral angle of 14.20 (9)°, and is nearly perpendicular to the mean plane through the tetralone moiety and to the methoxyphenyl ring [dihedral angles = 83.41 (8) and 72.12 (9)°, respectively]. The crystal packing is stabilized mainly by van der Waals forces.
Socio-emotional Experience in Human Technology Interaction Design – A Fashion Framework Proposal
2021
Technology designers and developers can be understood as social experience (SE) mediators. In user experience (UX), notions of SE have served to identify and define the factors contributing to human-technology interaction (HTI). Three dominant perspectives have been promoted in UX discourse: 1) SE of brand, brand value and consumer culture; 2) technology design as mediator of human-to-human interactions; and 3) meaning generation through action and interaction between actors. Symbolic interactionalism understands meaning as occurring through dialogue, in the construction of the social self, promoting self-reflection as a social construction. This theorisation of social experience is valuabl…
Le non-public et la culture. Une étude de cas en banlieue
2012
Photographic exhibitions are organized since 2004 on the banks of the river Marne at Fleury-la-Rivière within the context of an annual event --the Festival de l'Oh!, initiated by the conseil général of the Val-de-Marne. This type of exhibition does not succeed in attracting the "non-public". The representations held by the people concerned can block their interaction with the works presented on such a public space. This study is part of an on-going general study of the non-public and its relation to culture. This is a qualitative study carried out in various "stops" of the Festival de l'Oh! The paper is only concerned with immigrants met in housing estates in the upper districts of Fleury.
Howard S. Becker e gli “approcci moderni” nello studio dei problemi sociali
2018
The article discusses the intellectual biography of sociologist Howard S. Becker taking into account his contribution to the sociological study of social problems. Becker believes in the possibility of an objective study of the properties of social problems. However he admits that the objective properties of a phenomenon are neither sufficient nor necessary to define something as a “social problem”.
Approximate Taylor methods for ODEs
2017
Abstract A new method for the numerical solution of ODEs is presented. This approach is based on an approximate formulation of the Taylor methods that has a much easier implementation than the original Taylor methods, since only the functions in the ODEs, and not their derivatives, are needed, just as in classical Runge–Kutta schemes. Compared to Runge–Kutta methods, the number of function evaluations to achieve a given order is higher, however with the present procedure it is much easier to produce arbitrary high-order schemes, which may be important in some applications. In many cases the new approach leads to an asymptotically lower computational cost when compared to the Taylor expansio…

La tulipe, l'androgyne et le vulgaire. Sexe en Derrida
2016
L'autrice retrouve dans "La carte postale" la véritable position de Jacques Derrida sur la question de la différence sexuelle qui hante son oeuvre dès le début.
A study of the atmospherically important reactions of dimethylsulfide (DMS) with I2 and ICl using infrared matrix isolation spectroscopy and electron…
2012
The reactions of dimethylsulfide (DMS) with molecular iodine (I(2)) and iodine monochloride (ICl) have been studied by infrared matrix isolation spectroscopy by co-condensation of the reagents in an inert gas matrix. Molecular adducts of DMS + I(2) and DMS + ICl have also been prepared using standard synthetic methods. The vapour above each of these adducts trapped in an inert gas matrix gave the same infrared spectrum as that recorded for the corresponding co-condensation reaction. In each case, the infrared spectrum has been interpreted in terms of a van der Waals adduct, DMS : I(2) and DMS : ICl, with the aid of infrared spectra computed for their minimum energy structures at the MP2 lev…
