Virtual environments have shown considerable promise as a natural (and thus it is hoped more effective) form of human-computer interaction. In a virtual world you can use your eyes, ears, and hands much as you do in the real world: move your head to set your viewpoint, listen to sounds that have direction, reach out your hands to grab and manipulate virtual objects. Virtual worlds technologies ...

T HE experiment involved 48 pairs of male Holstein fraternal twin calves. Two methods of raising calves were contrasted: (A) High fat (20%) and protein (20%) vealer ration fed from 3 days of age to a market weight of 128 kilograms. (B) The same vealer was fed up to a live weight of 56.7 kg, followed by pelleted grain mixture fed ad libitum and hay offered to a maximum of 0.9 kg per day. Twin pa...

abstractâ cultural norms state human-nature interaction by affecting individual and group values system. ethical norms are the most important ones in which nature and its components become evaluated based on ethical views. there are different ethical normative views toward human-nature interaction. they have been currently categorized into three types of anthropocentric, bio centric and eco cen...

Background—Particulate air pollution has been associated with cardiovascular mortality and morbidity. Transition metals such as iron bound to the particles may be responsible for those associations. The protein product of the hemochromatosis (HFE) gene modulates uptake of iron and divalent cations from pulmonary sources and reduces their toxicity. Two HFE polymorphisms (C282Y and H63D) associat...

We discuss three aspects of the interaction between GRB and their surroundings. The illumination of the progenitor remnant and/or the surroundings by the X-ray afterglow continuum can produce substantial Fe K-alpha line and edge emission, with implications for the progenitor model. The presence of large dust column densities, capable of obscuring the GRB optical afterglow, will lead to characte...

The spread of mobile devices into the streets combined with the growing interest in interactive technologies in public settings raise a host of new challenge for human computer interaction. This study investigates the use of public displays in promoting the sense of community through the public self-expression. The approach involves a temporary interactive art installation that promotes people’...
