Optical quality of hyperopic and myopic phakic intraocular lenses

2013

Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…

Les normes comptables actuelles permettent-elles une comptabilisation des stock-options à leur juste valeur?

2006

In many countries, executive stock options (ESOs) have been subject to financial scandals during these last years, that encountered for a deep need of transparency, particularly about this compensation device for managers. The aim of this paper is to present, in a first part, the ways of expensing ESOs in through the European IRFS 2 and the American FAS 123 standards. The second part analyses ESOs accounting and its consequences, namely regarding the requirements about measuring this incentive mechanism at its fair value.

Gas geochemistry of shallow submarine vents in the Aegean sea (Greece)

2017

The Aegean area, which is geodynamically very active, is characterised by intense seismic activity, presence of active volcanic systems and anomalous geothermal gradients. Like other regions of intense geodynamic activity it is also characterized by extensive geogenic degassing. Gas manifestations are not only widespread on land but are also very frequent underwater. Many of these, as for example those of Milos and Santorini, are known since long time and have been previously studied although the targets were generally the hot waters or the sediments affected by the emissions (Smith and Cronan 1978, Dando et al. 1995, Price et al. 2013, Megalovassilis 2014).The present study aims at produci…

6-Methyluracil: a redetermination of polymorph (II)

2019

6-Methyluracil, C5H6N2O2, exists in two crystalline phases: form (I), monoclinic, space group P21/c [Reck et al. (1988). Acta Cryst. A44, 417–421] and form (II), monoclinic, space group C2/c [Leonidov et al. (1993). Russ. J. Phys. Chem. 67, 2220–2223]. The structure of polymorph (II) has been redetermined providing a significant increase in the precision of the derived geometric parameters. In the crystal, molecules form ribbons approximately running parallel to the c-axis direction through N—H...O hydrogen bonds. The radical differences observed between the crystal packing of the two polymorphs may be responsible in form (II) for an increase in the contribution of the polar canonical forms…

Knowledge, attitude, and practice of the use of ready-to-eat vegetables among potential consumers of Palermo (Italy).

2007

The knowledge, attitude, and practice toward the use of ready-to-eat vegetables were evaluated in a sample of 701 (388 women and 313 men) potential consumers in Palermo, by answering to an anonymous questionnaire handed out. Food safety perceptions and behaviors were analysed; in general, interviewed consumers who perceived higher risks exhibited safer food behaviors. There weren't considerable differences in the use of these salads between two sexes; 81.4% of respondents uses these products to save a lot of time, particularly the graduates attach importance to saving in time (p = 0.001), and only 34.4% is worrying about high price. Statistical analysis showed a significant correlation betw…

Naturalne spoiwa kostek nawozowych jako element zrównoważonej uprawy roślin

2016

Zrównoważona uprawa roślin, stawiająca nowe wymagania praktyce rolniczej, dąży do ograniczania wykorzystania nawozów mineralnych na rzecz długo działających nawozów organicznych. W szczególności cenne są te nawozy, które powstają w obrębie gospodarstwa z uwagi na ich wysoką jakość oraz brak kosztów związanych z zakupem i transportem. Zwłaszcza materia organiczna zawarta w odpadach przemysłu spożywczego lub powstająca w gospodarstwach domowych, przy braku zanieczyszczeń innymi rodzajami odpadów, może służyć do wytwarzania nawozu, który mógłby być wykorzystywany nawet w organicznej produkcji roślin uprawnych. W pracy przedstawiono wyniki badań wiązania organicznych i mineralnych komponentów n…

Comparisons of individual bitterness perception and vegetable liking and consumption among Danish consumers:A pilot study for a cross-cultural sensor…

2012

In order to enhance the consumption of bitter and strong tasting vegetables such as cabbages and root vegetables, it is required to identify potential mediators of sociodemographic–diet relationships. In this context a consumer field studywas conducted in Denmark which comprised a semi-quantitative food frequency questionnaire, a bitter threshold value test kit with quinineand a preference test with two samples of carrots differing in the degree of bitterness. All tests were conducted outside the laboratory, and the subjects (n=116, aged 18 to 79) were recruited during two different events at two sites in April and June 2011.Data was subjected to multivariate data analysis in order to eluci…

Gouvernement d'entreprise et comptabilité

1999

L'objectif de cet article est d'une part, de mettre en évidence les limites de l'approche actionnariale du gouvernement des entreprises pour appréhender le rôle de la comptabilité, d'autre part, de montrer l'intérêt d'une approche partenariale comme réponse aux limites de l'approche actionnariale.
