Uusi hengityksen filosofia
2018
Lectio praecursoria 28.9.2018 Hengitys on hyvin harvinainen teema filosofiassa. Aiemmin hengitystä filosofisena kysymyksenä ovat tarkastelleet mm. Luce Irigaray ja David Kleinberg-Levin. Väitöskirjatutkimuksessani Phenomenological Ontology of Breathing tutkin fenomenologisesti hengityksen filosofiaa, so. miten hengittäminen voisi olla filosofinen kysymys ja miten eletty kokemus hengityksestä voisi mahdollisesti avata ja jäsentää meille aivan uuden tavan tehdä filosofiaa. Väitöskirjani lähtökohtana on aiemmin tutkimattomat Maurice Merleau-Pontyn fenomenologiset huomiot hengityksestä. Näiden Merleau-Pontyn hengitystä koskevien huomioiden pohjalta pyrin jäsentämään uuden fenomenologisen käsity…
In Pursuit of Measuring Pre-reflective Music Listening Experiences
2022
While the diverse effects and uses of music and sound have been extensively documented within music psychology, relatively little attention has been paid to the process and experience of listening itself. Previous literature have, however, considered different ways of attending to sounds via the concept of listening modes, which highlights the different ways and strategies through which listeners intentionally orientate themselves to the activity of listening and creating the experiential meaning of the sound. In this paper, we continue on these lines by focusing on the very basic attentional dispositions for listening that often remain unconscious. As op posed to more deliberate and intent…
Computer aided scheduling and routing of vehicle-carrier fleet—a case study
2016
This paper presents a case study of development of an information system for a large enterprise from vehicle-transport industry. A novel optimization model and algorithms developed to solve scheduling and routing of vehicle-carrier fleet are presented and discussed. Carried out qualitative experiments confirmed the usability of developed user-guided search paradigm and high performance of autonomous algorithmic solution search methods.
Structural distortions in homoleptic (RE)4A (E = O, S, Se; A = C, Si, Ge, Sn): Implications for the CVD of tin sulfides
2001
The structures of Sn(SBut)4 and Sn(SCy)4 have been determined and adopt S4 and D2 conformations respectively; the anion [(PhS)Sn3]−, as its Ph4P+ salt, has a structure approaching Cs symmetry. In all three compounds, there are large variations in the ∠S–Sn–S within the same molecule, which have been rationalised in terms of the C–S–Sn–S–C conformations. For Sn(SR)4, the ∠S–Sn–S increases as the conformations change from trans, trans to trans, gauche and gauche, gauche, as the number of eclipsed lone pairs decreases and this rationale is shown to be applicable to a variety of A(ER)4 (A = C, Si, Ge, Sn; E = O, S, Se) and related [Mo(SR)4, Ga(SR)4−] systems. AM1 calculations have been used to …
Deposition of tin sulfide thin films from tin(iv) thiolate precursors
2001
AACVD (aerosol-assisted chemical vapour deposition) using (PhS)(4)Sn as precursor leads to the deposition of Sn3O4 in the absence of H2S and tin sulfides when H2S is used as co-reactant. At 450 degreesC the film deposited consists of mainly SnS2 while at 500 degreesC SnS is the dominant component. The mechanism of decomposition of (PhS)(4)Sn is discussed and the structure of the precursor presented.
The Synthesis of Quinoline‐based Tin Complexes with Pendant Schiff Bases
2019
Whilst pursuing the synthetic utility of quinoline‐based tin complexes, Me2Sn(Quin‐NO2)2 (1) and Ph2Sn(Quin‐NO2)2 (2) (Quin‐NO2 = 5‐nitroquinolino‐8‐oate) were synthesized bearing coordinatively inert nitro groups. Conventional reduction methodologies successfully converted 1 to Me2Sn(Quin‐NH2)2 (3) and 2 to Ph2Sn(Quin‐NH2)2 (4) (Quin‐NH2 = 5‐aminoquinolino‐8‐oate). The synthetically useful amine groups proved difficult to exploit in the presence of the central tin atom, however, a complete Schiff base functionalized Sn complex of the dimethyltin pro‐ligand Me2Sn(Quin‐py)2 (6) was successfully synthesized from 5‐[(pyridin‐2‐ylmethylene)amino]quinolin‐8‐ol (HQuin‐py; 5) in good yield via an …
El retablo de San Estanislao de Kostka en San Luis de los franceses de Sevilla
2020
El templo de San Luis de los franceses de Sevilla, construido a lo largo de las primeras décadas del siglo XVIII, dispone de un complejo programa visual. El retablo de San Estanislao de Kostka ocupa una importante capilla, en paralelo a la de San Francisco de Borja. Como todo retablo, cumple dos funciones: la contemplativa, o conductora de la oración a través de su imagen conceptual, y la formativa por medio del discurso visual desplegado en las calles laterales y el ático. Se afronta el análisis de ambas facetas mediante una aproximación a sus fuentes literarias y emblemáticas.
High-quality superconducting titanium nitride thin film growth using infra-red pulsed laser deposition
2018
Superconducting titanium nitride (TiN) thin films were deposited on magnesium oxide, sapphire and silicon nitride substrates at 700 °C, using a pulsed laser deposition (PLD) technique, where infrared (1064 nm) pulses from a solid-state laser were used for the ablation from a titanium target in a nitrogen atmosphere. Structural studies performed with x-ray diffraction showed the best epitaxial crystallinity for films deposited on MgO. In the best films, superconducting transition temperatures, T C, as high as 4.8 K were observed, higher than in most previous superconducting TiN thin films deposited with reactive sputtering. A room temperature resistivity down to ~17 μΩ cm and residual resist…
New Insights into Segmental Packing, Chain Dynamics and Thermomechanical Performance of Aliphatic Polyurea Composites: Comparison between Silica Oxid…
2021
Polyurea (PU) is intrinsically reinforced by its microphase-separated morphology, giving its excellent mechanical properties. In this study, it is shown how a high-index PU formulation applies easy diffusion of hard segments into the soft phase of the PU matrix and tune its chain mobility. Moreover, the interaction of micro (>100 nm), nano (<100 nm) fillers with the microdomains and their thermomechanical properties are unraveled. Herein, nanosilica oxide (NS) and micro titanium (III) oxide (Ti2O3) are incorporated at low loadings into a solvent-free two-component aliphatic PU via insitu polymerization. While NS achieves an interfacial interaction with urea groups and forms a tight ha…
Calcium mediated polyelectrolyte adsorption on like-charged surfaces.
2011
International audience; Monte Carlo simulations within the primitive model of calcium-mediated adsorption of linear and comb polyelectrolytes onto like-charged surfaces are described, focusing on the effect of calcium and polyion concentrations as well as on the ion pairing between polymers and calcium ions. We use a combination of Monte Carlo simulations and experimental data from titration and calcium binding to quantify the ion pairing. The polymer adsorption is shown to occur as a result of surface overcharging by Ca2+ and ion pairing between charged monomers and Ca2+. In agreement with experimental observations, the simulations predict that the polymer adsorption isotherm goes through …
