introduction: vertical root fracture (vrf) is a complication which is chiefly diagnosed radiographically. recently, film-based radiography has been substituted with digital radiography. at the moment, there is a wide range of monitors available in the market for viewing digital images. the present study aims to compare the diagnostic accuracy, sensitivity and specificity of medical and conventi...

background: in high-intensity, mixed and pulsed neutron fields the use of spectrometers or area monitors with active detectors is useless in these conditions neutron measuring devices must have a passive detector. here a passive neutron area monitor with cr39 track detector was designed and the response was calculated. materials and methods: the response of a passive neutron area monitor with c...

background: workstation design has shift from using single monitor screen to dual monitor screens, which may impose some impacts towards the muscles activity. this study aimed to determine the effect of using dual monitor screen computer to the neck-shoulder muscle activity among computer user. method: this experimental study was conducted in 2015 among 28 healthy students in university malaysi...

This paper reports on the effects of an interactive software tool on the learning of Chinese tones by English-L1 learners of Chinese. The software enables students to listen to model utterances by native speakers of Chinese and to record their own renditions of those utterances. Simultaneously the F0 contours of both the model utterances and the student utterances are displayed on the computer ...

Some interests might feel threatened by the results of his research, but professor Johansson has been outspoken and committed to this scientific field. He started in the 1980's and he has since been continuously very productive and an advocate for the electrosensitive persons in Sweden as well as around the world. This interview will go into what professor Johansson has discovered in the skin o...

Running Head: The effect of visual sources on the perception of compliance using a toolABSTRACT This paper describes a psychophysical experiment which investigates the effect of the source of vision on the perception of compliance with a specific focus on palpation; a basic surgical task. Twelve participants were asked to complete four forced-choice compliance discrimination tasks representing ...

The routine top-up operation of Taiwan Light Source (TLS) began in October 2005. The beam stability and integrated flux were drastically improved. Various diagnostics are needed to support the top-up operation. These tools include diagnostics for measuring beam charge and current and injection efficiency, as well as a filling pattern monitor, a tune monitor, and an instability and loss pattern ...

Previous studies have provided evidence of multi-level mental representations of language-conveyed spatial (scenic) information. However, the available evidence is largely inconclusive with regard to the structure of these mental representations. A laboratory experiment assesses computer-assisted problem-solving performance abilities when language-conveyed representations of spatial information...

The search for faster ways to get fractal pictures onto the computer screen leads to new problems on Latin squares.
