Abstract: A novel dust free alginate impression material was formulated and prepared, comprising an alginate polyvinylpyrrolidone and tetraflouroethylene resins, a mixture of liquid paraffin and dimethylpolysiloxane oil as the dust generation controlling agents and processed diatomaceous earth filler which was obtained from Iranian ore. No dusting was detected during the mixing of the powde...

In this paper, we propose a music evaluation method. In this method, impressions of given music are represented by features by value, so that the music impressions are processed on computers. To obtain the music impressions, we experiment music impressions by using a semantic differential method. Then, we construct several models based on the experimental results with multiregression analysis. ...

We present results from a study connecting status characteristics theory and affect control theory. Replicating a previous study (Dippong and Kalkhoff 2015), we examine the relationship between affective impressions and general performance expectations. The current study builds on previous work by employing an experimental setting specifically designed to isolate status as the sole basis of soc...

background and aims. the condensation silicone impression materials are available, but there is little knowledge of their accuracy after disinfection. the objective of this study was to evaluate the effect of the disinfection by spray atomization on dimensional accuracy of condensation silicone impressions. materials and methods. impressions were made on a stainless steel master model containin...

An in vitro study was performed to ascertain the marginal seal elemental composition of amalgam restored extracted teeth of known marginal leakage. Occlusal cavities were cut in 400 caries free extracted teeth and left unlined or lined with one of 5 bases. A varnish was applied to half the cavities followed by restoration with a low copper or high copper amalgam to produce 20 restoration combin...

Electrosurgical vessel sealing has been demonstrated to have benefits for both patients and practitioners, but significant variation in the strength of the seal continues to be a concern. This study aims to examine the variation in electrosurgical seal quality along the length of a porcine common carotid artery and explore the relationships between seal quality, vessel size and morphology. Addi...

Aerial low-frequency (100-6400 Hz) hearing thresholds were obtained for one California sea lion (Zalophus californianus), one harbor seal (Phoca vitulina), and one northern elephant seal (Mirounga angustirostris). Underwater thresholds over a similar frequency range (75-6300 or 6400 Hz) were obtained for these three animals in addition to another California sea lion. Such data are critical, not...
