Agents, usually topical, that relieve itching (pruritus).
The vapor state of matter; nonelastic fluids in which the molecules are in free movement and their mean positions far apart. Gases tend to expand indefinitely, to diffuse and mix readily with other gases, to have definite relations of volume, temperature, and pressure, and to condense or liquefy at low temperatures or under sufficient pressure. (Grant & Hackh's Chemical Dictionary, 5th ed)
Presence of warmth or heat or a temperature notably higher than an accustomed norm.
The processes of heating and cooling that an organism uses to control its temperature.
A broad group of eukaryotic six-transmembrane cation channels that are classified by sequence homology because their functional involvement with SENSATION is varied. They have only weak voltage sensitivity and ion selectivity. They are named after a DROSOPHILA mutant that displayed transient receptor potentials in response to light. A 25-amino-acid motif containing a TRP box (EWKFAR) just C-terminal to S6 is found in TRPC, TRPV and TRPM subgroups. ANKYRIN repeats are found in TRPC, TRPV & TRPN subgroups. Some are functionally associated with TYROSINE KINASE or TYPE C PHOSPHOLIPASES.

  • these are not toxic or noxious (although water vapor and carbon dioxide are greenhouse gases that contribute to global warming ). (
  • And greenhouse gases such as carbon dioxide actually help to cool the upper atmosphere, where the clouds form. (
  • Greenhouse gases tend to cool the stratosphere while warming the near-surface layers. (
  • The Paris Agreement was intended to turn the world onto a new path, one that would limit the risks and impacts from climate change through lowered emissions of carbon dioxide and other greenhouse gases. (
  • Under the Paris Agreement, 178 nations have committed to reducing their emissions of carbon dioxide and other greenhouse gases. (
  • Envelop of the greenhouse gases encircling our atmosphere acts like the windscreen of the car and does not allow the Sun's rays to go back to go back. (
  • It is not that that this envelop of greenhouse gases has appeared all of a sudden in our atmosphere. (
  • Quantum phenomena at extremely low temperatures are fervently studied both theoretically and experimentally in contemporary physics. (
  • Physicists have been able to create an atomic gas that can attain a temperature below absolute zero, -273.15˚C. They were able to create this gas using negative-Kelvin materials and new quantum devices. (
  • Ulrich Schneider, a physicist at the Ludwig Maximilian University in Munich, Germany, and his colleagues reached a sub-absolute zero temperature with an ultracold quantum gas that was made up of potassium atoms. (
  • Here in the experiment the quantum gases are in a fourth state like ionic core of sun or central core of earth, where they they descend from the gaseous state. (
  • Quantum gases - collections of atoms cooled to the lowest known temperatures in the universe, have sparked a revolution in atomic physics. (
  • Taking advantage of the precise control and purity available in atomic systems, quantum gases are now being used to address a range of questions in many-body quantum physics. (
  • We have developed a technique to obtain local measurements of homogeneous parameters in a harmonically trapped quantum gas and used this to make in situ observations of pair condensation in a unitary Fermi gas. (
  • The contact is a recently introduced parameter to characterise universal properties of strongly interacting quantum gases. (
  • The stability of these complexes in the gas phase is investigated by quantum chemical methods (DFT-M06). (
  • Research covers a wide range of areas, from fundamental wave phenomena and quantum system to liquid crystals, ultracold atomic gases, quantum optics and nanofabricated metamaterials. (
  • Dr. Vladimir Melezhik of RUDN University is engaged in calculations of resonant phenomena and collision processes in ultracold quantum gases. (
  • Quantum gas is retained at ultralow temperatures in an optical trap formed by specially tuned laser beams. (
  • The experimental technique makes it possible to control and tune the parameters of such quantum systems: the number of particles, their spin composition, temperature, and the effective interaction between atoms. (
  • These quantum waves store the energy of the system, and the more particles that are removed from the gas, the less intense these waves become. (
  • For us it is crucial that the gas behaves more and more quantum mechanically at low temperatures", says Jörg Schmiedmayer. (

  • Temperatures of a system are read off from a graph that plots the probabilities of its particles being found with certain energies. (
  • In theory, if more particles have higher energies, the plot would flip around and the sign of the temperature would change from positive to negative. (
  • We could for the first time observe a negative absolute temperature for mobile particles. (
  • Negative absolute temperature cannot be attained in a Singularity state in which there is zero distance between the elementary particles such as the pre-Big-Bang gravitons singularity. (
  • It can be attained with other particles which arrive at non-zero inter distance in their state of minimum motion, minimum energy level, by lowering temperature. (
  • These factors are water, cold temperatures and 'seed' particles onto which the water can condense. (
  • The particles that make up a liquid or a gas have different energies", says Professor Jörg Schmiedmayer (TU Wien). (
  • Therefore, a simple trick can be used to cool down cold gases: with the help of electromagnetic fields, the particles with the highest energy are removed from the gas. (
  • When the fastest particles are gone, no other particles in the gas will ever have the same speed again. (
  • The older theory suggested that a constant flux of tiny dust particles from space introduces carbon monoxide into the gas giant's atmosphere. (

  • What exactly are the surface temperatures on these rocky worlds and gas giants that make them inhospitable to life as we know it? (
  • What this means is that the side exposed to the Sun remains exposed for some time, allowing surface temperatures to reach up to a molten 465 °C. Meanwhile, on the dark side, temperatures can drop off to a frigid -184°C. Hence, Mercury varies between extreme heat and extreme cold and is not the hottest planet in our Solar System. (
