  2. Systemic acquired resistance - Wikipedia

    en.wikipedia.org/wiki/Systemic_acquired_resistance

    Systemic acquired resistance (SAR) is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen. SAR is analogous to the innate immune system found in animals, and although there are many shared aspects between the two systems, it is thought to be a result of convergent evolution. [ 1 ]

  3. Specific absorption rate - Wikipedia

    en.wikipedia.org/wiki/Specific_absorption_rate

    Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field. It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg).

  4. Acute radiation syndrome - Wikipedia

    en.wikipedia.org/wiki/Acute_radiation_syndrome

    Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1]

    en.wikipedia.org/wiki/Hypersensitive_response

    It is analogous to the innate immune system found in animals, and commonly precedes a slower systemic (whole plant) response, which ultimately leads to systemic acquired resistance (SAR). [1] HR can be observed in the vast majority of plant species and is induced by a wide range of plant pathogens such as oomycetes, viruses, fungi and even ...

    The banner line might read SECRET//MEDIAN BELL//SPECIAL ACCESS REQUIRED, and the portion marking would read (S//MB). [18] Other variations move the special access warning to a second line, which would read MEDIAN BELL Special Control and Access Required (SCAR) Use Only or some other phrase directed by the program security instructions.

    The structure–activity relationship (SAR) is the relationship between the chemical structure of a molecule and its biological activity. This idea was first presented by Alexander Crum Brown and Thomas Richard Fraser at least as early as 1868.
