Background & Aims: Exposure Keratitis (EK) is a common problem in critically ill patients admitted to the Intensive Care Unit (ICU). We conducted exposure keratitis in mechanical ventilatory patients in the intensive care unit of Imam Khomeini Hospital in Urmia for five years. Materials & Methods: In this retrospective cross-sectional study, the records of the patients were taken from the medi...

An international comparison has been conducted to compare the illuminance responsivity scales (A/lx) and the units of luminous  ux (lm) maintained at the National Institute of Standards and Technology (NIST, USA) and the Helsinki University of Technology (HUT, Finland). Both laboratories realize the illuminance unit by absolutely calibrated photometers and the luminous  ux unit by the absolut...

The switch control unit module is a critical core control module of the all-electronic computer interlocking system. Switch in the wrong place as the top event, use the Relex software for quantitative analysis of the importance of analysis method and found a key part of the module designs. The weak link in the system design through the use of the ‘2-Vote-2’ modular architecture analysis showed ...

BACKGROUND Most of general practitioners (GPs) use advertising in their waiting rooms for patient's education purposes. Patients vaccinated against seasonal influenza have been gradually lessening. The objective of this trial was to assess the effect of an advertising campaign for influenza vaccination using posters and pamphlets in GPs' waiting rooms. METHODS AND FINDINGS Registry based 2/1 ...

BACKGROUND Excessive alcohol consumption has been linked to deleterious health consequences among undergraduate students. There is a need to develop theory-based and cost-effective brief interventions to attenuate alcohol consumption in this population. PURPOSE The present study tested the effectiveness of an integrated theory-based intervention in reducing undergraduates' alcohol consumption...

PURPOSE To compare the visual performance of prototype contact lenses which extend depth-of-focus (EDOF) by deliberate manipulation of multiple higher-order spherical aberration terms and a commercially-available center-near lens (AIR OPTIX Aqua Multifocal, AOMF). METHODS This was a prospective, cross-over, randomized, single-masked (participant), short-term clinical trial where 52 participan...

Backtracking strategies based on the computation of discrepancies have proved themselves successful at solving large problems. They show really good performance when provided with a high-quality domain-specific branching heuristic (variable and value ordering heuristic), which is the case for many industrial problems. We propose a novel approach (PDS) that allows parallelizing a strategy based ...
