The experiments were performed in a manipulated office setting containing a constant source of d-limonene and an ozone generator that was remotely turned "on" or "off" at 6 h intervals.
A constant current generator (maximum skin impedance of 2.2 KΩ) generates biphasic rectangular impulses with an electrical mean equal to zero (preventive stimulation protocol: impulse width 250 μS, frequency 60 Hz, maximum intensity 16 mA).
An example of a constant force generator is the constant-force spring.
This is a constant current generator that produces a train of biphasic square-wave pulses (60 Hz, 1 ms/phase) to minimize the possibility of inducing a seizure.
An intraluminal catheter was used for PES, connected to a constant current generator (DS7, Welwyn-Garden City, UK) and a trigger generator (Neurolog system, Digitimer) allowing titration of stimulation intensity against individuals' perception and tolerance thresholds.
The plight of the bee, in Britain and elsewhere, has been a constant headline generator as their decline attributed to multiple factors like climate change, disease, pesticides, parasites has caused huge concern because bees are excellent pollinators.
A constant current generator (I-ON XL, Sooft, Montegiorgio, FM, Italy) was used, with a setting range of 1 mA for 5 minutes.
In Lagos the steady buzzing of generators is a constant reminder of the government's failure to provide basic power needs.
Liu et al. [206], by pulsing the gate bias using a pulse generator with a constant anode bias of 40 kV, showed a stable 0.3 mA temporal response over 15 h with an approximate pulse rise time of <5 ms.
While some managers reported that their facilities had non-functioning electricity generators, most facilities that had functioning generators did not have a constant supply of fuel.
It's been an up at six and a constant state of gas lines and generators and building fires to stay warm.
