For fluorescence excitation, 510 nm and 640 nm pulsed diode lasers (PicoQuant) were electronically synchronized to the depletion beam and an electronic delay (Colby Instruments) allowed adjustment of the relative arrival time of the laser pulses at the sample.
Several scientists at the planetary-science conference questioned why the Europa mission was losing out even as the budget of another flagship NASA mission, the $2.4-billion 2.4-billioned to launch to Marover 2020, has ballooned, mostly because of delays in instrument developlanned
At this construction site, the arrival of the Boston Symphony's instruments delays the loading of sheetrock into elevators, and a Frank Sinatra concert requires the removal of scaffolding around the front door.
If a laser pulse from the LIDAR can be detected on the ground, a two-way range is measured by subtracting the internal delay in the instrument, expressed as STOP1 TIMING + START TIMING.
The phases are measured by the tone signal that is produced by the pulse at near-signal frequencies, and the delay produced in the instruments can also be calculated.
Intensifier gate delays were adjusted using a computer-controlled electronic delay line (HDG, Kentech Instruments Ltd) that was synchronized to the excitation laser.
In Nicholas Adams's script, both sides play dirty tricks (stolen bus wheels and musical instruments, silly delays at customs), with the goal of keeping the other band from competing.
"Talks will not go on for the sake of talks, and talks cannot become an instrument for delay that in the end make the situation more dangerous," Mr. Kerry said.
Although the jury's still out on whether expensive brain training programs are of any benefit to overall brain health, there is some evidence that keeping your brain active by reading, doing puzzles, or learning a new language or musical instrument could delay the onset of Alzheimer's disease and other forms of dementia.
Despite those maneuvers, Secretary of State John Kerry said at a news conference in Saudi Arabia on Monday that "talks will not go on for the sake of talks" with Iran, "and talks cannot become an instrument of delay that will make the situation more dangerous.
