Then there's ultraviolet light.

And then I put some ultraviolet filters on my camera and took a very, very long exposure with the particular frequencies of ultraviolet light and this is what I got.

The field of Hypercomputation studies models of computation that go beyond normal Turing computation.

Vitamin D The human body can synthesize vitamin D when skin is exposed to ultraviolet radiation from the sun.

Solar radiation is energy in the form of electromagnetic radiation from the infrared (long) to the ultraviolet (short) wavelengths.

History The project to develop ALSA was led by Jaroslav Kysela, and was based on the Linux device driver for the Gravis Ultrasound sound card.

Transfinite numbers are numbers that are infinite in the sense that they are larger than all finite numbers, yet not necessarily absolutely infinite.

There's been no doubt around my colleagues about the utility of the training I received here, and I think there's been an increased interest now in particularly in echocardiography and its use in our setting.

As for drinking water quality, there are concerns about disinfection by products, lead, perchlorates and pharmaceutical substances, but generally drinking water quality in the U.S. is good.

A wide range of remote monitoring techniques and technologies exist, outside of normal regulatory oversight, e.g. hyperspectral imaging systems and satellite imagery.

So digital mammography has been a giant leap forward for manufacturers of digital mammography equipment, but it's been a very small step forward for What about ultrasound?

For two years, I searched for a fiber that could survive ultraviolet rays, salt, air, pollution, and at the same time remain soft enough to move fluidly in the wind.

If we had UV eyes or X ray eyes, we would really see the dynamic and dramatic effects of our Sun's magnetic activity the kind of thing that happens on other stars as well.

We're also starting ancillary health care technology training programs training people in echocardiography, cardiac ultrasound, those kinds of things. Now, with that kind of training, it gives people motivation.

(a) Relaxation study of the interaction between the exhaust products of turbojet engines and the upper strata of the Earth's atmosphere by examining the images and spectra obtained in the ultraviolet range.

As the temperature increases, the peak shifts to shorter wavelengths, producing first a red glow, then a white one, and finally a blue white colour as the peak moves out of the visible part of the spectrum and into the ultraviolet.

Within about 20 minutes of ultraviolet exposure in light skinned individuals (three to six times longer for pigmented skin), the concentrations of vitamin D precursors produced in the skin reach an equilibrium, and any further vitamin D produced is degraded.

And you see activity in some regions we've seen today, medial prefrontal cortex, dorsomedial, however, up here, ventromedial prefrontal cortex, anterior cingulate, an area that's involved in lots of types of conflict resolution, like if you're playing Simon Says, and also the right and left temporoparietal junction.
