Typically, bats emit calls at a low rate while cruising, but, if they detect an insect, the rate of emissions speeds up to give a "capture buzz" as the bat closes in on the prey.
Multi-sensory signals such as acoustic emission, vibration, speed and torque are collected from the gearbox test rig under different health and operating conditions.
Ionic wind has been shown to influence soot emission, propagation speed, and stability of flames; however, a detailed behavior of ionic wind and its effects on flames is still not clear.
Open image in new window Figure 9 Soot and NO x emission versus speed for constant- and variable- r c engines for minimum bsfc.
Open image in new window Figure 14 Soot and No x emission versus speed for constant- and variable-compression-ratio engines.
Fluorescence was recorded for each concentration (355 nm excitation, 450 550 nm emission, scan speed of 200 nm/min, 3 and 5 nm slit widths for the excitation and emission pathways), 1 min after addition of the protein 25°C.
With its combination of low emissions, high speed and snazzy design, this might prove to be a bus that is worth waiting for.
This paper assesses shipping profits, costs and emissions by speed and as a function of sea and freight market conditions.
In Tuvalu, a tiny, low-lying South Pacific nation, locals worried that the growth of China's greenhouse gas emissions could speed global warming, which looked likely to eventually inundate their country.
Mr. Popovich said he hoped that the new Congress would be more aggressive in holding regulators to account for the cost of new rules and would send signals to the administration to slow down new regulations on carbon dioxide emissions and speed up the granting of new mine permits.
