A propeller is a type of fan that transmits power by converting rotational motion into thrust.

In principle, all countries should be represented at some time in all United Nations bodies, on a rotational basis, if necessary.

The long crankshafts of the latter suffered from an unacceptable amount of flex when engine designers began using higher compression ratios and higher rotational speeds.

Paleontological evidence on the Earth's rotational history suggests that 1.8 billion years ago, there were about 450 days in a year, implying 20 hour days.

A molecular vibration occurs when atoms in a molecule are in periodic motion while the molecule as a whole has constant translational and rotational motion.

The quality of CCAs and UNDAFs is now overseen by the regional directors of agencies working together at the country level and coordinated on a rotational basis by one of the agencies.

Finally, we agreed with Singapore to deploy up to four Littoral Combat Ships there on a rotational basis to join it and other countries in the region for exercises, training, and responses to challenges.

Photometric light curve observations of NEOs are also carried out to determine rotational properties and, in some cases, to detect companion moons (a significant fraction of NEOs have turned out to be binary asteroids).

And as they slide their hand down the lever, they can push with a smaller effective lever length, but push through a bigger angle every stroke, which makes a faster rotational speed, and gives you an effective high gear.

In support of this increased engagement aimed not at establishing new permanent bases, but rather at building stronger allies and partners through a greater rotational presence the third pillar of America s rebalancing is to enhance our presence across the Pacific and Indian Oceans.

The Ex Press Bar, on the third floor of the General Assembly Building, will serve as an overflow area for the media, in particular for the official photographers and cameramen waiting to enter the booth which will be assigned to them on a rotational basis.

The quality of the UNDAFs (and Common Country Assessments (CCAs), where they are being undertaken) is overseen by the Regional Directors of the agencies working in each country, and the leadership for this quality assurance is coordinated on a rotational basis by one of the agencies.
