| By using electricity or sources that emit less atmospheric pollutants as a means of propulsion, BRANCHÉ enables a notable improvement urban air quality. |
|
| When pursuing prey, they emit a higher pitched howl, vibrating on two notes. |
|
| These isotopes emit different types and levels of radiation, which last for different periods of time. |
|
| The dolphins emit these strident sounds when in the presence of other individuals moving towards the same prey. |
|
| They emit clicking sounds and listen for the return echos to determine the location and shape of nearby items, including potential prey. |
|
| They emit penetrating gamma radiation that is much more of a hazard than the alpha or beta radiation from cesium, cobalt, strontium or polonium,' LaMastra said. |
|
| Airglow is an atmospheric phenomenon in which photons from the sun excite air molecules, which eventually emit light at several specific wavelengths. |
|
| He said that the nation will get the real freedom and self-reliance when chimneys will emit smoke and not through a musical show of a political adventurist. |
|
|
|
| The female rat will also emit ultrasonic vocalizations during mating. |
|
| Poplar, willow or eucalyptus trees, all used as fast-growing sources of renewable wood fuel, emit high levels of the chemical isoprene as they grow, the study said. |
|
| Bluish flickers visible in ocean water at night often come from blooms of bioluminescent dinoflagellates, which emit short flashes of light when disturbed. |
|
| Other nuclear materials such as Americium 241, which is found in modern smoke detectors, emit a much higher gamma radiation and is much more abundant. |
|
| The phosphor particles used in this study emit green light and are composed of ytterbium and erbium as respective absorber and emitter ions embedded in a preceramic matrix. |
|
| A star made of anti-matter, which would be converting antihydrogen into antihelium, would emit antineutrinos and could therefore be told from a star burning normal matter. |
|
| Using an electrometer, an invention of Pierre's that measured small currents of electricity, Marie began measuring uranium's ability to emit radiation. |
|
| Active instruments emit energy and record what is reflected. |
|
| Various species of both freshwater and sea turtles emit numerous types of calls, often short and low frequency, from the time they are in the egg to when they are adults. |
|
| Rats may also emit short, high frequency, ultrasonic, socially induced vocalization during rough and tumble play, before receiving morphine, or mating, and when tickled. |
|
| Formaldehyde-releasing compounds which emit small amount of the chemicals are considered to be carcinogenic while isothiazolinones are regarded as skin sensitisers. |
|
| By applying quantum field theory to a static black hole background, he determined that a black hole should emit particles that display a perfect black body spectrum. |
|
| Wafers of gallium arsenide and other semiconductors that can transmit electrons at high speeds and efficiently emit or detect light are costly and fragile. |
|
| They emit calls outside this range to avoid deafening themselves. |
|
| Hence, large black holes emit less radiation than small black holes. |
|
| Their experiments show that ultrasonic irradiation of a cold liquid creates microscopic hot spots that emit light similar to that given off by high-temperature flames. |
|
| It is built to divert methane moving eastward toward the buildings and emit it into the environment, dispersing it into nonexplosive concentrations. |
|
| There, he had used radio waves to probe the secrets of pulsars, the spinning, magnetized neutron stars that emit bursts of radiation with clocklike regularity. |
|
| If challenged during the rut, a buck will emit a clicking sound. |
|
| Only when an unlucky star approaches too close and gets shredded by the black hole's powerful tidal forces does the galactic center emit a bright flare of light. |
