large rays lacking venomous spines: mantas.
Those rays which are near the axis are sometimes called paraxial rays.
Meanwhile, the newly real particles decay, giving off (among other things) light, X-rays and gamma rays.
"Science has also helped develop entirely new methods of treatment. Radiotherapy for example, makes use of x-rays and radioactive rays to treat cancer."
Plant puberulent, at least around nodes and rays; ultimate segments of leaves not elongate-linear.
Denser tissues, such as bones, absorb more X rays and show as lighter areas on X-ray film.
The rays is Hermes orange red, I turned my hat over because I was so boring, and let the orange red mirrored on the white label.
"Converging lens caus3es the rays of a parallel beam of light to come closer and pass through a point, i.e. the rays converge. It produces a real image at its principal focus. Such a lens is thicker at the center than the edge"
The next day dawned bright and clear, and the new rays of the sun, radiating up from the horizon, revealed that the Kao compound was quite unharmed - except for a few broken roof tiles and a piece that had been knocked off the roof of the left wing.
bright rays on lunar surface
large primitive rays with elongated snouts.
Every so often the sun emits a gigantic burst that includes highly energized x-rays gamma rays and charged particles.
Tests also found that both the red and orange pigments collect ultraviolet rays.
In 1932 the Joliot-Curies made a radioactive metal bombard beryllium--which is a non-radio-active metal--with its rays. The result was that the beryllium, too, became radioactive- even more so than the original source of the rays.
Standing wave is parasitic effect of exposure, generated by multi reflection and interference of rays vertically incident upon parallel medium layers.
Plastics do not contain dioxins, and the sun's rays are not strong enough to create them, says Michael Trush, PhD, deputy director of the Johns Hopkins Center for Urban Environmental Health.
Cosmic rays and X-rays produce energetic electrons by ionization.
Cathode rays are attracted by a positive charge.
The supernova explosions that create and spread heavy elements also unleash a torrent of high-energy radiation: gamma rays, X-rays, and ultraviolet light.
As Lesley Alderman reports in this week's Patient Money column, snow reflects nearly 80 percent of the sun's rays. That means more harmful ultraviolet rays are directed into your eyes.
From cross sections of stems-cuttings, a primordium of adventitious roots originates from the cross region of pith rays and vascular cambium.
I don't know. How many seconds can the memory last? Do not want to let the hot rays of light drying those flowing in the years of tenderness, want you to let me stay in the sky at the moment, let all the fairy tales soak in the right temperature.
Other forms of radiant energy familiar to us are radio waves, infrared rays, ultra - violet rays, X rays, and gamma rays.
To find out, they turned to thehigh-power X-rays generated at the Stanford Synchrotron Radiation Lightsourcein California, this time measuring how water scatters rays arrivingfrom various angles.
wild aster with fernlike leaves and flower heads with very narrow bright purple rays; Alberta to Texas and Mexico.
When jets spat out by a at the centre of a galaxy collide with dark matter, they could produce gamma rays detectable from Earth - possible evidence of the elusive dark stuff.
Through the dark robe oft amber rays prevail.
In a flash, the rays of the sun shone all over for half a day, maintaining the golden sun of the golden sun, and countless golden rays were rippled across the water.
Facekini is popular in the Chinese city of Qingdao, where it is used by people for protecting themselves from tan inducing UV rays while in direct sunlight and from jellyfish while at the beach.
The sun’s UV rays can degrade and prematurely age wine.
Melanin has an extremely important role- it absorbs UV light and dissipates the UV rays as heat.
The researches are concerned with alpha rays.
As the need for dental care increases, dentists continue to rely heavily on their hygienists for cleaning, X-rays, and preventative care.
He concentrated the sun's rays on the Roman ships besieging the city and burned them.
Eye rays (Su) : Each of a beholder's ten eye rays resembles a spell cast by a 13th level caster.
This is necessary because the infrared rays have longer wave lengths than the visible light rays you see and focus with, and the camera lens focuses them slightly further back inside the camera.
bottom-dwelling tropical rays: skates.
"One of the most revolutionary areas of modern surgery is that of organ transplants. With the, use of x-rays and special drugs scientists succeeded in transplanting tissues from one person to another. They will survive for periods of a year of more."
