3631. EuroSLAB - The rheology of the subducting slab and mantle : Final report EuroSLAB Trieste IPSandro Scandolo, Luigi Giacomazzi, 2011, končno poročilo o rezultatih raziskav Opis: The aim of this Individual Project was to study the microscopic phenomena of
deformation in mantle minerals by means of atomistic modeling. Understanding such
mechanisms and determining their relative importance in different minerals and in the
wide range of pressure and temperature found in the mantle, is a prerequisite for any
interpretation of deformation experiments, of texture modeling, and of their
geophysical implications.
The project was approved for funding in mid 2006, and was carried out in large
part in collaboration with a postdoctoral fellow funded by CNR (Luigi Giacomazzi),
whose fellowship ended on December 15, 2009.

3633. Investigating silica from first-principlesLuigi Giacomazzi, druga izvedena dela Opis: Silica (SiO2 ) is a prototypical binary compound showing a complex
phase diagram. It is the most abundant mineral in the Earth’s crust,
and it has many important technological applications. From a
theoretical point of view, SiO2 is a benchmark requiring both accurate
atomistic models and a multi-scale approach. As an example of the
capabilities of state- of-the-art theoretical modeling, we discuss the
vibrational spectra of vitreous SiO2 with particular attention to the
information that these spectra can provide on the medium-range
structure of the oxide network. Then, as an example of multi-scale
approach we present our work on dislocations in coesite within the
framework of the Peierls-Nabarro model.

3634. Elided Clausal Conjunction Is Not the Only Source of Closest‐Conjunct Agreement: A Picture‐Matching StudyBoban Arsenijević, Jana Willer-Gold, Nadira Aljović, Nermina Čordalija, Marijana Kresić, Nedžad Leko, Frane Malenica, Franc Marušič, Tanja Milićev, Nataša Milićević, Petra Mišmaš, Ivana Mitić, Anita Peti-Stantić, Branimir Stanković, Jelena Tušek, Andrew Nevins, 2019, izvirni znanstveni članek Opis: A recurring hypothesis about the agreement phenomena generalized as closest‐conjunct agreement takes this pattern to result from reduced clausal conjunction, simply displaying the agreement of the verb with the nonconjoined subject of the clause whose content survives ellipsis (Aoun, Benmamoun & Sportiche 1994, 1999; see also Wilder 1997). Closest‐conjunct agreement is the dominant agreement pattern in the South Slavic languages Slovenian and Bosnian/Croatian/Serbian. A natural question is whether closest‐conjunct agreement in these varieties may indeed be analyzed as entirely derived from conjunction reduction. In this article, we report on two experiments conducted to test this. The results reject the hypothesis as far as these languages are concerned, thereby upholding the relevance of models developed to account for closest‐conjunct agreement within theories of agreement.

3635. Photothermal lens technique: a comparison between conventional and self-mixing schemesHumberto Cabrera, Imrana Ashraf, Fatima Matroodi, Evelio E. Ramírez-Miquet, Jehan Akbar, Jose Juan Suárez-Vargas, John Fredy Barrera Ramírez, Dorota Korte, Hanna Budasheva, Joseph J. Niemela, 2019, izvirni znanstveni članek Opis: This work focuses on assessing the analytical capabilities of a new photothermal lens method based on the self-mixing effect to reliably measure metallic traces in water-ethanol solutions. We compare it with the conventional thermal lens scheme, considering the low detection limit and versatility. A theoretical model is presented to describe the laser power variations as a function of the photothermal parameters of the analyzed sample. The experimental results demonstrate that the laser intensity variations, induced by the external optical feedback, are governed by
the photothermal lens effect. Measurements of Fe(II)-1,10-phenanthroline in water–ethanol solutions show a favourable correspondence and agreement with the theory. The low detection limits obtained by the two analytic techniques also agree very well. Nevertheless, our instrument presents advantages regarding compactness and simplicity, suggesting that this platform could be potentially useful as a robust analytical tool for metallic trace detection. In addition, calibration of the method is performed by measuring the so-called self-mixing constant.
