Carbon from the oil can diffuse into the steel, making the surface very hard.

The waters become hard like stone, when the surface of the deep is frozen.

The lake surface was at an altitude of 1,916 m above sea level.

The purpose sought is the neutralization of a number of stationary surface, semi hard or lightly armoured targets.

An environmental psychologist told me, If you're sitting in a hard chair on a rigid surface, you'll be more rigid.

high wing, the wing upper surface is level with or above the top of the fuselage.

Geoid To extend this definition far from the sea means comparing the local height of the mean sea surface with a level reference surface, or datum, called the geoid.

They tend to be an upper level fish, often swimming directly below the surface of the water.

The surface of Lake Malawi is located at above sea level, with a maximum depth of , which means the lake bottom is over below sea level at some points.

Countries should establish surface and groundwater quality monitoring networks at the national level in order to protect their scarce water resources

To inhibit corrosion, at least 11 chromium is added to steel so that a hard oxide forms on the metal surface this is known as stainless steel.

The location dependent, but persistent in time, separation between mean sea level and the geoid is referred to as (stationary) ocean surface topography.

If the saving rate now rises quickly to that level, it will be hard to keep overall GDP growing.

Similar to surface tension, adsorption is a consequence of surface energy.

Parts and components of liquid propellant surface to air missiles can also be reused in a surface to surface role, like the liquid propellant engines of the SA 2 missiles used in the Samoud 2 surface to surface missiles.

It is a lot more sophisticated than a microwave oven, but it is basically boiling the water molecules in the very surface level of your skin.

A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island.

True enough. But, without economic growth, the political will to take hard measures at the national level is unlikely to be forthcoming.

Work hard, play hard.

Next, the walls are constructed on a flat level surface with insulation and interior Sheetrock before being lifted by crane into position and secured to the floor sections.

It was also during the Northern Renaissance that Flemish brothers Hubert and Jan van Eyck perfected the oil painting technique, which enabled artists to produce strong colors on a hard surface that could survive for centuries.

Finally, surface temperature is used.

But a common market requires a level playing field, and the European Commission has worked hard to achieve this in many sectors over the years.

Nearly half of the Japanese population is either retired or near retirement age, and they worked very hard to achieve a high level of comfort.

Chua would reply that reaching a high level of achievement brings great satisfaction, and that the only way to do it is through hard work.

Six thousand kilometers below the surface, the planet s core is as hot as the surface of the sun.

The energy of the laser heats the surface of the pellet into a plasma, which explodes off the surface.

Air and Surface Movement Control Unit

Well, the surface of the spray coating is actually filled with nanoparticles that form a very rough and craggly surface.

When surface temperature drops, eventually reaching the dew point, atmospheric water vapor condenses to form small droplets on the surface.

At the most basic level, governments must take a hard look at conscription and territorial defense forces, which eat up far too much of Europe s military budgets.

They also work hard to make a living in a country where median household income has declined to a level last seen in the mid 1990 s.

If the rules for the universe are simple, it's kind of inevitable that they have to be very abstract and very low level operating, for example, far below the level of space or time, which makes it hard to represent things.

Although i486SX devices were not used at all when the i487 was installed, they were hard to remove because the i486SX was typically installed in non ZIF sockets or in a plastic package that was surface mounted on the motherboard.

With a surface area of approximately 1,560 km² (602 mi²), depending on the current water level, it is one of the largest reservoirs in the world, flooding nearly one percent of the country.

And then for the damaged arthritis on the surface, we did a stem cell paste graft, which we designed in 1991, to regrow that articular cartilage surface and give it back a smooth surface there.

This utilises a property of and other materials specifically that a thin layer of gold on a high refractive index glass surface can absorb laser light, producing electron waves (surface plasmons) on the gold surface.

It generally involves making marks on a surface by applying pressure from a tool, or moving a tool across a surface.

You're getting better, but it's hard. Why is it hard?

Single surface products. Furniture's a good one.

Water flows on the surface and underground.

Beneath the surface are many threatening cracks.
