  2. Joule–Thomson effect - Wikipedia

    en.wikipedia.org/wiki/Joule–Thomson_effect

    The gas-cooling throttling process is commonly exploited in refrigeration processes such as liquefiers in air separation industrial process. [7] [8] In hydraulics, the warming effect from Joule–Thomson throttling can be used to find internally leaking valves as these will produce heat which can be detected by thermocouple or thermal-imaging ...

  3. Flash evaporation - Wikipedia

    en.wikipedia.org/wiki/Flash_evaporation

    If the throttling valve or device is located at the entry into a pressure vessel so that the flash evaporation occurs within the vessel, then the vessel is often referred to as a flash drum. [1] [2] If the saturated liquid is a single-component liquid (for example, propane or liquid ammonia), a part

  4. Isenthalpic process - Wikipedia

    en.wikipedia.org/wiki/Isenthalpic_process

    The throttling process is a good example of an isoenthalpic process in which significant changes in pressure and temperature can occur to the fluid, and yet the net sum the associated terms in the energy balance is null, thus rendering the transformation isoenthalpic. The lifting of a relief (or safety) valve on a pressure vessel is an example ...

  5. Hypersensitive response - Wikipedia

    en.wikipedia.org/wiki/Hypersensitive_response

    An example of this can be observed in plant resistance to the rice blast pathogen, where the RGA5 NLR has a heavy-metal-associated (HMA) domain integrated into its structure, which is targeted by multiple effector proteins. [15] An example of indirect recognition: AvrPphB is a type III effector protein secreted by Pseudomonas syringae.

  6. Thermonasty - Wikipedia

    en.wikipedia.org/wiki/Thermonasty

    It is a form of nastic movement, not to be confused with thermotropism, which is a directional response in plants to temperature. A common example of this is in some Rhododendron species, but thermonasty has also been observed in other plants, such as Phryma leptostachya. [1]

  7. Plant physiology - Wikipedia

    en.wikipedia.org/wiki/Plant_physiology

    A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...

  8. Cold hardening - Wikipedia

    en.wikipedia.org/wiki/Cold_hardening

    Cold hardening is a process in which a plant undergoes physiological changes to avoid, or mitigate cellular injuries caused by sub-zero temperatures. [1] Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C.

  9. Gravitropism - Wikipedia

    en.wikipedia.org/wiki/Gravitropism

    Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it. It also occurs in fungi. Gravity can be either "artificial gravity" [clarification needed] or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms.
