The dissociated early embryonic cells of the fresh water fish, Oryzias latipes, protrude hyaline lobopodia, which tend to rotate around the cell circumference in a propagating wave. Cells from late blastula or gastrula continuously show this "circus movement", while most cells up to early blastula are rounded. The linear velocity of the lobopodium was estimated by means of time-lapse cinemicrog...

The objective of this work was to demonstrate the effect of fluoride and propolis extract on the corrosion behavior of commercially pur titanium (cp-Ti grade 2) in artificial saliva. The inhibition studies were approved out on cp-Ti as dental implant in Fusayama-Meyer with the propolis extract using potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS). Parameters, such ...

Such research often relies on the results of immersion tests in aqueous chloride solutions, which have generally proven to be highly appropriate for a quick characterisation and classification of the corrosion resistance of the different magnesium alloys. Corrosion tests in chloridecontaining media may, however, be subject to a serious problem as has been noted by several authors [1-3], in that...

The use of composite materials has expanded in industrial applications around the world, reinforcing composites with waste like (chicken feather) is one effective ways to solve environmental concerns compared traditional methods, as it considered renewable and inexpensive methods addition its presence abundance. main added features over classic are light-weight. This paper investigates effect i...

The spread of digital media and communications in the lives of children and youth have raised new questions about the role of media in learning, development and cultural participation. In post-industrial societies, young people are growing up in what Henry Jenkins (2006) has dubbed “convergence culture”—an increasingly interactive and participatory media ecology where Internet communication tie...

Background The aim of this paper is to explore how contextualization of a healthcare simulation scenarios impacts immersion, by using a novel objective instrument, the Immersion Score Rating Instrument. This instrument consists of 10 triggers that indicate reduced or enhanced immersion among participants in a simulation scenario. Triggers refer to events such as jumps in time or space (sign of ...

Previous research studies in the context of presence point out the importance of personality factors. Surprisingly, the relation between immersion and the Big Five personality factors has not yet been examined. Hence, we assessed these traits in an online survey (N = 220) and relate them to immersive tendency, a disposition that determines whether someone is receptive to immersive experiences d...

High Definition Television (HDTV) is the new generation broadcasting system, proposing a deeper immersion in action and better visualization comfort. New material is used (flat television screens, fast connection, high media storage, etc.) allowing better user experience than standard definition television (SDTV). Higher hardware prices will only be accepted if noticeable higher quality is reac...

Inaccessibility of instructional materials, media, and technologies used in science, engineering, and mathematics education severely restricts the ability of students with little or no sight to excel in these disciplines. Curricular barriers deny the world access to this pool of potential talent, and limit individuals' freedom to pursue technical careers. Immersion has developed a low-cost forc...

In collaboration with the Stanford University Medical Media and Information Technologies center (SUMMIT), Immersion Corporation has designed and developed a new haptic simulation interface for minimally invasive surgical simulators. This device, shown in Figure 1, features two similar master manipulators that each have five degrees of freedom equipped with haptic feedback. The centers of the gi...
