Instead, the helixes, functioning like microscopic machines, can be controlled with electrical currents to make them longer or shorter, acting like tiny prisms, reflecting the bands of the spectrum needed to render the required colors.
The anodization current was controlled with a programmable current source (Keithley 6221, Keithley Instruments Inc., Cleveland, OH, USA).
The light intensity was controlled with a variable current LED driver, and the fraction of cis-isomerized protein was monitored with a diode array UV vis spectrophotometer (Ocean Optics Inc., USB4000).
The gas pressure is controlled by the needle valve and discharge current is controlled with the control knob in the PPD source power supply.
The current and voltage were controlled with a measurement unit (model 236, Keithely Instruments Inc., Cleveland, OH, USA). Figure 1a shows the chemical structures of FIrpic, mCP, and TPBi materials of blue PHOLEDs.
It also allowed the potential confounding effect of massage to be controlled for in this current study, with aromatherapy intervention groups with and without massage.
The rated capacity of RPC is 100 VA, and the RPC uses IPM bridge circuit configuration which is controlled by DSP2812 with hysteresis current PI control.
They claim the fish have either been implanted with magnets or are being controlled by harmful electric currents.
The Markov models that we used introduce temporality into analyses to assess relationships that markers of depression in the prior year had with current CVD risk factors once the associations that prior risk factor status had with current status were controlled.
Eligible patients had to be 18 years of age or older, of either gender, and had to present a documented diagnosis of T2D that had been inadequately controlled with their current hypoglycemic therapy.
