Dysprosium chloride fires, however, can be extinguished with water, while dysprosium fluoride and dysprosium oxide are non-flammable.

Dysprosium fires cannot be put out by water.

Dysprosium carbonate, Dy < sub > 2 </ sub >( CO < sub > 3 </ sub >)< sub > 3 </ sub >, and dysprosium sulfate, Dy < sub > 2 </ sub >( SO < sub > 4 </ sub >)< sub > 3 </ sub >, result from similar reactions.

Dysprosium also has at least 11 metastable isomers, ranging in atomic mass from 140 to 165.

Dysprosium is obtained primarily from monazite sand, a mixture of various phosphates.

About 100 tonnes of dysprosium are produced worldwide each year, with 99 % of that total produced in China Dysprosium prices have climbed nearly twentyfold, from $ 7 per pound in 2003, to $ 130 a pound in late 2010.

Dysprosium is never encountered as a free element, but is found in many minerals, including xenotime, fergusonite, gadolinite, euxenite, polycrase, blomstrandine, monazite and bastnäsite ; often with erbium and holmium or other rare earth elements.

Dysprosium is used, in conjunction with vanadium and other elements, in making laser materials and commercial lighting.

Dysprosium is a rare earth element that has a metallic, bright silver luster.

Dysprosium was first identified in 1886 by Paul Émile Lecoq de Boisbaudran, but was not isolated in pure form until the development of ion exchange techniques in the 1950s.

Dysprosium ( ) is a chemical element with the symbol Dy and atomic number 66.

Dysprosium is never found in nature as a free element, though it is found in various minerals, such as xenotime.

Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications, and as a component of Terfenol-D. Soluble dysprosium salts are mildly toxic, while the insoluble salts are considered non-toxic.

Dysprosium and holmium have the highest magnetic strengths of the elements, especially at low temperatures.

Dysprosium has a simple ferromagnetic ordering at temperatures below.

Dysprosium halides, such as DyF < sub > 3 </ sub > and DyBr < sub > 3 </ sub >, tend to take on a yellow color.

Dysprosium oxide, also known as dysprosia, is a white powder that is highly magnetic, more so than iron oxide.

Dysprosium is one of the components of Terfenol-D, along with iron and terbium.

Dysprosium is used in dosimeters for measuring ionizing radiation.

Dysprosium iodide and dysprosium bromide are used in high intensity lighting.

Dysprosium nitrate, Dy ( NO < sub > 3 </ sub >)< sub > 3 </ sub >, is a strong oxidizing agent and will readily ignite upon contact with organic substances.

Dysprosium titanate is a new material currently undergoing evaluation for pressurized water control rods.

Curly hair, high cheekbones, wide gnomelike mouth, a pair of drummer's blocky hands, and a body that said well, maybe I can wrestle you for ten minutes -- but then I'm finished.

It is well then that in this hour both of `` national peril '' and of `` national opportunity '' we can take counsel with the men who made the nation.

If man is actually the product of his environment and if science can discover the laws of human nature and the ways in which environment determines what people do, then someone -- a someone probably standing outside traditional systems of values -- can turn around and develop completely efficient means for controlling people.

Where, then, can we look for improvement??

What can a mother do then to prevent misbehavior??

If it will simply delay the debates until the qualifications are closed next spring, and then carry all the candidates on a tour of debates, it can provide a service to the state.

As this tax base grows so then can your medium and low density residential areas grow.

Whether the compromises -- on both sides -- that made possible the interim appointment can then be repeated remains to be seen.

`` Unless the oyabun has been working on it '', he said, then checked himself and added: `` You can tell Kayabashi-san that the back road is in very good condition and will be quite safe for his party to use ''.

What type of action can hope to win public support, first in this country and then abroad??

It can then grow steadily as it proves itself and as the need for it is demonstrated.

During nighttime hours, because of the intense skywave propagation then prevailing, no large number of stations can be permitted to operate on one of these channels, if the wide area service for which these frequencies are assigned is to be rendered satisfactorily by the dominant stations which must be relied upon to render it.

Here then is our problem: aircraft are vital to winning a war today because they can perform those missions which a missile is totally incapable of performing ; ;

Multiplication, subtraction, and addition can then be accomplished as they appear in the equation by starting at the left end of the equation and working toward the right.

You can save all that shimming time if you set your windows in one, two, three order -- first the stud on one side, then the window, then the stud on the other side.

For those who need or want and can afford another car, buying one and driving it on the grand tour, then shipping it home, is one popular plan for a do-it-yourself pilgrimage.

If the vertex is at Af, and if the interior of C is on the left as one moves in the direction of increasing t, then every such corner can be found from the curve obtained by rotating C clockwise through 90-degrees about the vertex.

Thus if E is sufficiently small, there can be only one intersection of C and Af near Q, for if there were more than one intersection for every E then the difference between C and Af near Q would not be a monotone function.

Now the only way in which all curves of the image family of Af can pass through a fixed point is to have a generator of Af which is not a secant but a tangent of **zg, for then any point on such a generator will be transformed into the point of tangency.

But if no two lines of the regulus of multiple secants of **zg can intersect, then the regulus must be quadratic, or in other words, **zg must be either a Af or a Af curve on a nonsingular quadric surface.

In the written language then can be underlined or italicized to guide the reader here, but much of the time the written language simply depends on the reader's alertness, and a careless reader will have to back up and reread.

and these costs must somehow be apportioned among the various classes and then must somehow be reapportioned among the units of service in order to report unit costs that can serve as tentative measures of reasonable rates.

If the patient can perceive figure kinesthetically when he cannot perceive it visually, then, it would seem, the sense of touch has immediate contact with the spatial aspects of things in independence of visual representations, at least in regard to two dimensions, and, as we shall see, even this much spatial awareness on the part of unaided touch is denied by the authors.
