Th e research about the determinants of fi rms' performance has been a crucial question for managers, researchers and stockholders. Th e main objective of this exploratory paper is to study the economic drivers of revenue per available room (RevPAR) in the Portuguese hotels. Th is study examines the local and global factors driving RevPAR in diff erent hotel segments, calculating how much of th...

Imaging interferometric lithography, combining off-axis illumination, multiple exposures covering different regions of spatial frequency space, and pupil plane filters to ensure uniform frequency-space coverage, is a relatively new imaging concept that provides an approach to accessing the fundamental, linear-systems-resolution limits of optics. With an air medium between the lens and the wafer...

Using genotypic data (N = 1,816) from the National Longitudinal Study of Adolescent Health (J. R. Udry, 1998, 2003), the authors tested this possibility. They found that the 10R allele of the dopamine transporter (DAT1) gene was associated with self-reported delin...

Prop de quatre-centes persones estan matriculades ja en els cursos de voluntariat que la Universitat començà a impartir el passat divendres. El termini d’alguns d’ells, però, s’ha ampliat i es tancarà el proper dia 16. Els universitaris veuen en aquesta oferta la possibilitat d’adquirir una bona formació que els permetrà desenvolupar tasques de voluntariat en una ONG. Les inquietuds personals, ...

A sensitive and simple liquid chromatography/electrospray mass spectrometry (LC-ESI-MS) method for determination of cilostazol in rat plasma using one-step protein precipitation was developed. After addition of midazolam as internal standard (IS), protein precipitation by acetonitrile was used as sample preparation. Chromatographic separation was achieved on an SB-C18 (2.1 × 50 mm, 5.0 μm) colu...
