Plant responses to environmental cycles may even induce indirect cycles in rhizosphere microbial activities, including nitrogen fixation.
3.
Boiling water reactors ( BWRs ) are the second most common form of light water reactor with a direct cycle design that uses fewer large steam supply components than the pressurized water reactor ( PWR ), which employs an indirect cycle.
