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 ]
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).
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]
Dose required to kill a human with a 50% risk within 30 days (LD 50 /30), if the dose is received over a very short duration [53] [32] 5: Sv:
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.
A fast-spreading wildfire that erupted this week northwest of Los Angeles roared from nothing to nearly 10,000 acres − in a matter of hours.
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.
