Tolerance to rotation of toric monofocal and bifocal intraocular lenses. A theoretical study

2018

Abstract This manuscript aims to evaluate the tolerance to rotation of a toric monofocal and a toric bifocal intraocular lenses with different cylinder powers. Theoretical designs based on wavefront aberrations were created to simulate a toric monofocal and a toric bifocal intraocular lens. Cylinder power ranged from −1 D to −6 D, in steps of −1 D. Tolerance to rotation was estimated by the visual Strehl ratio based on the optical transfer function (VSOTF) metric. Tolerance to rotation for both monofocal and bifocal intraocular lenses decreased when the cylinder power increased. For the bifocal design studied, the tolerance to rotation was larger for the near focus than for the far, however…

Periodontal disease associated to systemic genetic disorders

2007

A number of systemic disorders increase patient susceptibility to periodontal disease, which moreover evolves more rapidly and more aggressively. The underlying factors are mainly related to alterations in immune, endocrine and connective tissue status. These alterations are associated with different pathologies and syndromes that generate periodontal disease either as a primary manifestation or by aggravating a pre-existing condition attributable to local factors. This is where the role of bacterial plaque is subject to debate. In the presence of qualitative or quantitative cellular immune alterations, periodontal disease may manifest early on a severe localized or generalized basis - in s…

Machine learning for land use change analysis and modelling.

2019

Urban development can take different forms or features, depending on its geographical location and its socioeconomic, political and cultural context. Nevertheless, the overall action relies on one fundamental principle: building construction in order to give people housing. Therefore, the main objective of this research is to determine whether an underlying universal aspect of the urban development process can be distinguished from a specific one, being the reflect of local specificities. Specifically, this research analyzes the land use change on the French-German cross-border area. Indeed, the border context enhances the difference within this territory. Nonetheless, the internal European…

Modulation transfer function in refractive-diffractive multifocal intraocular lenses in vitro

2007

Purpose: The optical quality of two types of multifocal, hybrid refractive-diffractive, intraocular lenses (IOL) is analyzed in vitro. Following the EN-ISO international standard, the IOLs’ modulation transfer functions (MTF) are determined for both distance and near vision. The behaviour of these curves when the pupil size varies is studied. Methods: The IOLs analyzed were: AcrySoft ResTor SN60D3 (Alcon) and Tecnis ZM900 (AMO). The MTF was calculated from the cross line-spread function recorded with the OPAL Vector System (Image Science Ltd. Oxford) by using fast Fourier transform techniques. The artificial eye model used simulates in vivo conditions of the anterior chamber including an ar…

La discussione ortografica tedesca a metà del Novecento: le Stuttgarter e Wiesbadener Empfehlungen.

2008

The twentieth century has been for the German orthography a period of several studies and discussions which gave scientific foundation to the 1996 spelling reform. There were plenty of public and private initiatives which, by involving an constantly increasing number of writers into the debates, tried to simplify the spelling to a more rational regulation. This essay focuses on the discussion in the late Fifties and especially on two reform projects: the Stuttgarter (1954) and the Wiesbadener Empfehlungen (1958). Despite their deeply different historical background from that of the recent successful reform, these projects are of fundamental interest for contemporary studies, since they give…

Russo: О чеховском критическом реализме в Италии узнали благодаря тем русским, которые пытались изменить политический режим в своей стране. Эмигранты, прибывшие сюда в период между революциями 1905-го и 1917 годов, нашли здесь доброжелательную аудиторию среди единомышленников-итальянцев – и этот культурный диалог оказался весьма плодотворным для обеих сторон. После первой революции русские прочно обосновались в Милане, Флоренции, Турине и Неаполе и посвятили себя усиленному изучению итальянской культуры. Большинство из них были революционерами – меньшевиками и большевиками, – на которых сильное влияние оказал Горький, человек необычайно яркий. В 1906 году он приехал в Неаполь из Соединенных…

Aussprachetraining im DaF-Unterricht in der Lehr- und Lernwelt 3.0.

2018

Everyone who acquires a new language at school or elsewhere has the right to learn good pronunciation. As phonetic errors are foreseeable, this paper begins by delineating deviations in (co)articulation and prosody which are typical of Italian learners of German, with the aim of examining how far these specific, predictable phonetic problems are treated in German textbooks used in Italy. The study shows that even modern textbooks do not consider phonetics in a satisfactory way. Today’s learning world 3.0 – not only interactive, but also shaped for the individual learner – is characterized by a growing number of Computer Assisted Language Learning (CALL) and special Computer Assisted Pronunc…
