) A single shallow convection cycle takes on the order of 50 million years, though deeper convection can be closer to 200 million years.

Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface.

A convection heat storage unit (CHS) system is similar to an ICS system, except the storage tank and collector are physically separated and transfer between the two is driven by convection.

Conduction, convection, and radiation all occur more rapidly over large thermal gradients.

Mechanical

This may be caused by the disappearance of a helium convection zone near the surface.

The occurrence of convection in the outer envelope of a main sequence star depends on the mass.

In the engineering sciences, heat transfer includes the processes of thermal radiation, convection, and sometimes mass transfer.

Within the context of a solar collector, convection and radiation are the most important sources of heat loss.

Dynamic mechanical analysis (abbreviated DMA, also known as dynamic mechanical spectroscopy) is a technique used to study and characterize materials.

Well, they can communicate through mechanical forces.

This ratio is called the mechanical advantage.

The convection between the relatively warm water and cold air in the winter plays an important role in the Arctic climate.

The element formula_2 is the open circuit mechanical impedance, that is, the impedance presented by the mechanical side of the transducer when no current is entering the electrical side.

Keynes understood early on the fallacy of applying such mechanical rules.

The mechanical properties of bone make it a good handle material.

The basic mechanical configuration is the same as the 50 series.

The pistol entered production at the Izhevsk Mechanical Plant in 1973.

It doesn't matter if your computer's mechanical, like Babbage's was, or electronic, like computers are today, or perhaps in the future, cells, or, again, mechanical again, once we get into nanotechnology.

Mechanical processes, including solids transportation, crushing and pulverization, and screening and sieving.

The mechanical counterparts of these properties are, respectively, mass, stiffness and damping.

This could be applied to problems that were entirely in the mechanical domain, but for mechanical filters with an electrical application it is necessary to include the transducer in the analogy as well.

Translating these electrical element values back into mechanical quantities provided specifications for the mechanical components in terms of mass and stiffness, which in turn could be translated into physical dimensions for their manufacture.

The university has also offered graduate programs in Electrical, Mechanical and Civil Engineering .

Consequently, mechanical wavelengths are much shorter than electrical wavelengths for the same frequency.
