Predicting the structure and vibrational frequencies of ethylene using harmonic and anharmonic approaches at the Kohn–Sham complete basis set limit

2016

In this work, regular convergence patterns of the structural, harmonic, and VPT2-calculated anharmonic vibrational parameters of ethylene towards the Kohn–Sham complete basis set (KS CBS) limit are demonstrated for the first time. The performance of the VPT2 scheme implemented using density functional theory (DFT-BLYP and DFT-B3LYP) in combination with two Pople basis sets (6-311++G** and 6-311++G(3df,2pd)), the polarization-consistent basis sets pc-n, aug-pc-n, and pcseg-n (n = 0, 1, 2, 3, 4), and the correlation-consistent basis sets cc-pVXZ and aug-cc-pVXZ (X = D, T, Q, 5, 6) was tested. The BLYP-calculated harmonic frequencies were found to be markedly closer than the B3LYP-calculated h…

Importância concedida à CTSA e Sustentabilidade em Revistas de Investigações Científicas Educacionais no Brasil e Espanha

2016

O objetivo deste estudo é evidenciar a evolução das investigações em educação em ciências no contexto Ciência-Tecnologia-Sociedade voltada para CTSA e Sustentabilidade no último par de décadas (1995–2014), no meio Ibero-americano. Nesse aspecto, foram analisadas as ocorrências de expressões relacionadas a CTSA, Sustentabilidade e outras vinculadas a estes termos em duas revistas de grande impacto e relevância na investigação didática no ensino de ciências e muito utilizadas por docentes e pesquisadores no âmbito dos países Ibero-americanos. Resultados apontam que embora tenha havido mudanças rumo às abordagens CTSA e Sustentabilidade na última década, estas mudanças ainda são tímidas em vir…

Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.

2016

Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…

AR METHODS FOR THE VISUALIZATION OF THE LOST MARBLE “TRIBUNA” IN THE MAIN APSE OF THE CATHEDRAL OF PALERMO

2022

Abstract. In recent years research works have shown that augmented reality tools can offer effective support for the dissemination of architectural heritage, when integrated into the information data extracted with surveying and representation tools and further data from other sources, e.g., history.The development and permanent updating of software platforms dedicated to augmented reality, i.e., Apple's ARKit and Google's ARCore, as well as the introduction of new features, offer today affordable support for the development of AR solutions.Some operational difficulties are due to the rapid and constant evolution of the technologies; the available solutions can be compared to prototypes and…

Bisphenol-A impairs insulin action and up-regulates inflammatory pathways in human subcutaneous adipocytes and 3T3-L1 cells.

2013

Current evidence indicates that chemical pollutants may interfere with the homeostatic control of nutrient metabolism, thereby contributing to the increased prevalence of metabolic disorders. Bisphenol-A (BPA) is a lipophilic compound contained in plastic which is considered a candidate for impairing energy and glucose metabolism. We have investigated the impact of low doses of BPA on adipocyte metabolic functions. Human adipocytes derived from subcutaneous adipose tissue and differentiated 3T3-L1 cells were incubated with BPA, in order to evaluate the effect on glucose utilization, insulin sensitivity and cytokine secretion. Treatment with 1 nM BPA significantly inhibited insulin-stimulate…

Danno all'ambiente e tutela della persona

2012

Il libro propone una riflessione sul danno ambientale, inquadrandola nella più ampia prospettiva della tutela della persona, alla quale la figura del danno ambientale sembra potersi ascrivere. Delineata la disciplina in tema di danno all'ambiente, quale emergente dal lungo iter normativo, dottrinale e giurisprudenziale, che ne ha segnato la sua evoluzione, emerge l'idea di un danno ambientale, che potrebbe definirsi esistenziale, in grado di suggerire riflessioni interessanti, tanto in tema di responsabilità ambientale, quanto riguardo all'area del danno alla persona. La parabola del danno ambientale, se continua forse oggi ad evocare pericolosi "mostriciattoli", è figlia della storia di un…

Between constitution and interpretation: Identity as history

2015

The paper focuses on the possibilities to constitute meaning in the „borderline- situations“ (Jaspers) of the social sphere, such as the loss of validity of orientation within and experience of reality in the socially shared structures of the lifeworld. On the one hand, I will refer to A. Schutz’ and his constitution-analysis of foreign understanding and of shared meaning; on the other hand, I bear onto I. Kertesz literary project to narrate the biography of an Auschwitz-survivor as close to his experiential perspective as possible. I will focus both on the concept of constitution and of interpretation with respect to their enabling of the transcending of a typologized everyday’s world whic…

The minimal model of Hahn for the Calvin cycle.

2018

There are many models of the Calvin cycle of photosynthesis in the literature. When investigating the dynamics of these models one strategy is to look at the simplest possible models in order to get the most detailed insights. We investigate a minimal model of the Calvin cycle introduced by Hahn while he was pursuing this strategy. In a variant of the model not including photorespiration it is shown that there exists exactly one positive steady state and that this steady state is unstable. For generic initial data either all concentrations tend to infinity at lates times or all concentrations tend to zero at late times. In a variant including photorespiration it is shown that for suitable v…
