This study attempted to evaluate and compare language learning apps and the related traditional books on the same subject. The apps included Murphy’s English Grammar and Cambridge Discovery Readers and the traditional materials were English Grammar in Use and Developing Reading Skills. The study, thus, aimed to do a comparative analysis between traditional ELT materials and the digital versions...

BACKGROUND Cataract surgery combined with excimer laser trabeculotomy (phaco-ELT) can reduce intraocular pressure (IOP). The aim of this study was to evaluate the effect of phaco-ELT on IOP in patients as a function of preoperative IOP. METHODS Patients with open-angle glacuoma or ocular hypertension who received phaco-ELT between 01/2008 and 10/2009 were included. Patients were assigned base...

In this paper we develop a methodology based on ballistics to estimate the landing footprint associated with the powered terminal descent phase of a Mars soft landing. The analysis is based on an idealized two-impulse thrust maneuver and leads to an analytical expression for the elliptical boundary of the landing footprint. Our goal was to develop a method (with low computational overhead) to e...

BACKGROUND Available models for designing the structure of specific simulation-based learning (SBL) activities need further analysis. METHOD This retrospective study was conducted using independent samples t tests to examine differences in mean clinical nursing judgment development scores between students who completed a nursing program prior to the introduction of an experiential learning th...

Aims. The variation of the expansion rate of the universe with time produces an evolution in the cosmological redshift of distant sources (for example quasars), that might be directly observed (over a decade or so) by future ultra stable, high-resolution spectrographs (such as CODEX) coupled to extremely large telescopes (such as ESO’s ELT). This would open a new window to explore the physical ...

In this paper we describe two approaches for solving the problem of scheduling aircraft landing times. In this problem, the air traac controller must compute a landing time for each aircraft in the horizon, and must attempt to minimise costs whilst observing a number of hard constraints. The costs are associated with aircraft landing times varying from the preferred landing time. The hard const...

In formalizing a ‘veil of ignorance’ type procedure, this paper considers how an agent’s preferences over a set of alternatives change as he is placed at an increasing ‘distance’ from the consequences of his choices. A definition for such ‘removed preferences’ is presented and its properties studied. As an application, it is demonstrated that decreasingly impatient agents are ‘essentially’ expo...
