powder metallurgy Treatment and coating of metals

Female condoms are also available, most often made of nitrile, latex or polyurethane.

The two components are referred to as a polyurethane system, or simply a system.

Polyurethane condoms tend to be the same width and thickness as latex condoms, with most polyurethane condoms between 0.04 mm and 0.07 mm thick.

We coat the inside with these bladder lining cells.

Gradually these cells differentiate and mature into specialized cells of the root tissues.

You place the vascular blood vessel lining cells on the inside.

The properties of a polyurethane are greatly influenced by the types of isocyanates and polyols used to make it.

As mentioned above, most condoms are made of latex, but polyurethane and lambskin condoms also exist.

And then another pair of legs we collaborated on were these look like jellyfish legs, also polyurethane.

Polyurethane (PUR and PU) is a polymer composed of a chain of organic units joined by carbamate (urethane) links.

It is unclear how common this allergy is in the general population.

So we made what people lovingly referred to as glass legs even though they're actually optically clear polyurethane, a.k.a. bowling ball material.

Flexible support The primary lining is thin and reflects recent strata conditions.

In the Kyoto area, tatami generally measure 0.955 m by 1.91 m. Tatami of this size are referred to as Kyōma tatami.

In the modern age, condoms are most often made from latex, but some are made from other materials such as polyurethane, polyisoprene, or lamb intestine.

It's a material hardener and synthetic estrogen that's found in the lining of canned foods and some plastics.

To confine the optical signal in the core, the refractive index of the core must be greater than that of the cladding.

BELGIUM Electrocoat Genk is a subsidiary of one of the world's biggest electrocoating businesses.

So this is a cinder block, uncoated, and you can see that it's porous, it absorbs water.

The coating also helps to decrease the temperature associated with the cutting process and increase the life of the tool.

EPO is produced mainly by interstitial cells in the peritubular capillary bed of the renal cortex.

Polyurethane condoms in particular, given they are a form of plastic, are not biodegradable, and latex condoms take a very long time to break down.

Progesterone appears to prevent endometrial cancer (involving the uterine lining) by regulating the effects of estrogen.

However, polyurethane condoms are less elastic than latex ones, and may be more likely to slip or break than latex, lose their shape or bunch up more than latex, and are more expensive.

The low tech bit is that it's literally a pig's heart valve mounted in the high tech bit, which is a memory metal casing.

After cyclotron irradiation, the coating was dissolved with nitric acid, and then precipitated as the hydroxide using concentrated aqueous ammonia solution.

The outer surface of an agate, freed from its matrix, is often pitted and rough, apparently in consequence of the removal of the original coating.

To ensure that the pyramid remained symmetrical, the exterior casing stones all had to be equal in height and width.

And here's the simplest version in nature, and here's my collaborator Ron Fearing's attempt at an artificial version of this dry adhesive made from polyurethane.

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

It is used in metallic films, which replace the wiring used in conventional electronics with a coat of tungsten (or molybdenum) on silicon.

They are attracted to the UV light, and are killed using an electric shock, or trapped once they come into contact with the device.

The tiger's stripes are also found on the skin, so that if it were to be shaved, its distinctive coat pattern would still be visible.

As niobium is oxidized at temperatures above 400 C, a protective coating is necessary for these applications to prevent the alloy from becoming brittle.

Some of the casing stones that once covered the structure can still be seen around the base.

The genome contains 250 genes involved in fatty acid metabolism, with 39 of these involved in the polyketide metabolism generating the waxy coat.

Accordingly, when the heart chambers are relaxed (diastole), blood will flow into the atria from the higher pressure of the veins.

A coating allows the cutting edge of a tool to cleanly pass through the material without having the material gall (stick) to it.

Animals with few sweat glands, such as dogs, accomplish similar temperature regulation results by panting, which evaporates water from the moist lining of the oral cavity and pharynx.

The male thylacine had a pouch that acted as a protective sheath, covering his external reproductive organs while he ran through thick brush.

Moving onto the next demonstration, we've taken a pane of glass and we've coated the outside of it, we've framed it with the nanotechnology coating, and we're going to pour this green tinted water inside the middle, and you're going to see, it's going to spread out on glass like you'd normally think it would, except when it hits the coating, it stops, and I can't even coax it to leave.

On this occasion 70 mirrors were used, each with a copper coating and a size of around five by three feet (1.5 by 1 m).

Polyurethane condoms have gained FDA approval for sale in the United States as an effective method of contraception and HIV prevention, and under laboratory conditions have been shown to be just as effective as latex for these purposes.

This coat contains long, stiff hairs, called kemps, over a short, woolly undercoat, which grows in autumn and is shed in spring.
