We present an interactive breadboard activity simulation (IBAS) to educate users in acquiring psychomotor skills in electrical circuitry pertaining to the ammeter, voltmeter and multimeter instruments. Psychomotor skills learning involves the association of cognitive functions with motor functions to make the task autonomous with repeated practice, and(More)
In an empirical evaluation, we examined the effect of viewing condition on psychophysical skills education in an interactive 3D simulation to train users in electrical circuitry. We compared an immersive head-mounted display (HMD)-based viewing metaphor versus a limited, desktop-based virtual reality (DVR) viewing metaphor with interaction using a spatial(More)
Hafnia alvei is a facultative and rod-shaped gram-negative bacterium that belongs to the Enterobacteriaceae family. Although it has been more than 50 years since the genus was identified, very little is known about variations among Hafnia species. Diversity in O-antigens (O-polysaccharide, OPS) is thought to be a major factor in bacterial adaptation to(More)
The regional eco-environment quality is the base of the sustainable development. This paper developed an eco-environmental vulnerability evaluation model using spatial principle component analysis (SPCA) and eco-environment vulnerability index method. This method was carried out in a case study of Hubei Province, China. The vulnerability was classified into(More)
