Glaucoma as a chronic and often asymptomatic disease in its early stages has a great influence on Quality of Life (QOL). Mostly because of disturbances in visual functions like damage to the visual field, lower visual acuity, the psychological impact of the diagnosis, side effects and the cost of treatment. Evaluation of QOL is very useful instrument which helps to decide about the ways of trea...

We report on the design and testing of a compact impact-ionization time-of-flight mass spectrometer for analysis of cosmic dust, suitable for use on deep space missions. The instrument, Dustbuster, incorporates a large target area with a reflectron, simultaneously optimizing mass resolution, particle detection, and ion collection. Dust particles hit the 65-cm target plate and are partially ioni...

BACKGROUND Little is known about the differences of rotary multiple file endodontic therapy and single-file reciprocating endodontic treatment under routine care conditions in dental practice. This multicenter study was performed to compare the outcome of multiple-file (MF) and single-file (SF) systems for primary root canal treatment under conditions of general dental practice regarding reduct...

Background. Contact allergy is characterized by local skin inflammation that, in some cases, can result in systemic immune activation. Objectives. To investigate whether IVIS SpectrumCT analyses can be used to detect the immune response induced by contact allergens. Methods. Micewere repeatedly exposed to vehicle or allergens on the ears. The local and systemic responses were analysed at differ...

PURPOSE To assess the impact of amblyopia, strabismus and glasses on subjective visual and psychological function among amblyopes. METHODS Questionnaires were administered to 120 teenagers with amblyopia (cases), with residual amblyopia after treatment, or with or without strabismus and 120 control subjects (controls) Cases underwent ophthalmic examination including cycloplegic refraction. Tw...

The visual occlusion technique has received considerable attention in recent years as a method for measuring the interruptible aspects of in-vehicle information system (IVIS) task performance. Because the visual occlusion technique lacks a loading task during “occluded” periods, an alternate method was adopted to provide increased sensitivity to the attentional costs of interruptions on IVIS-st...

Certain visual stimuli evoke perceptions of discomfort in non-clinical populations. We investigated the impact of stimuli previously judged as uncomfortable by non-clinical populations on a visual search task. One stimulus that has been shown to affect discomfort judgments is noise that has been filtered to have particular statistical properties (Juricevic et al, 2010 Perception 39 884-899). A ...

Investigating about a field consisting of numerous subfields would be insufficient if one only examines the subparts separately, because the intersections between them will be overlooked. Study of visual system is a good example in this respect. In a laboratory, we might be able to create a situation of having the impact of only one of the visual system subfields, but in the outside world, far ...

This paper demonstrates a technique for visualising multidimensional data sets holistically. The EVA algorithm provides an automatic mapping from semantically important features of the data to emotionally or perceptually significant features of the corresponding visual structure (such as a face). In other words a single glance at the visual structure informs the observer of the global state of ...
