background and aims. the most common method for alginate impression disinfection is spraying it by disinfecting agents, but some studies have shown that these impressions can be immersed, too. the aim of this study was to evaluate the dimensional stability of alginate impressions following disinfecting by spray and immersion methods. materials and methods. four common disinfecting agents (sodiu...

A hydrophobic surface with an antibacterial property has numerous uses, including self-cleaning, anti-sticking, anti-contamination, sports apparel, and wound healing/implant materials. The durability of the coating in aquas media (pH 7.4) is a vital requirement for use technical textile sectors, particularly medical applications. In this study, we used silica sol, chitosan hexadecyltrimethoxysi...

methods thirty healthy female volunteers aged between 18 and 30 years were treated by a 15-minute cryotherapy (6 ± 1°c). the subject's skin temperature over antromedial aspect of dominant ankle was measured by the mayomed device before, immediate and 15 minutes after water immersion. ankle jps was tested trough the pedal goniometer at 3 stages similar to the skin temperature. anova (α = 0.05) w...

In this paper, we discuss the potential role haptic, or touch, feedback might play in supporting a greater sense of immersion in broadcast content and describe some preliminary scenarios we have developed to explore how haptic content might be created and delivered within the context of a broadcast programme. In particular, this work has looked at two potential programme scenarios the creation ...

1 In this paper we describe the way in which emotion-related data can efficiently be exchanged between participants in a large-scale networked virtual environment. This type of metadata is extracted from real-time captured video streams using off-the-shelf webcams and applied onto a 2D stylized avatar; thereby improving the immersion the user experiences while navigating and communicating in th...

Sound gardens rely on location tracking technology to situate audio landmarks in public spaces, typically urban parks. These landmarks are surrounded by a proximity zone, and content relating to them is displayed to users within this region. In densely populated sound gardens, overlap between zones is inevitable and will result in simultaneous playback of multiple audio sources – a potentially ...

This paper describes the design, evaluation, and lessons learned from a project involving the implementation of an immersive virtual environment for children called NICE (Narrative-based, Immersive, Constructionist/Collaborative Environments). The goal of the NICE project was to construct a testbed for the exploration of virtual reality as a learning medium within the context of the primary edu...

In a stereophonic music production, music producers seek to impart impressions of one or more virtual spaces upon the recording with two channels of audio. Our goal is to map spaciousness in stereophonic music to objective signal attributes. This is accomplished by building predictive functions by exemplar-based learning. First, spaciousness of recorded stereophonic music is parameterized by th...
