When we become firm enough to stand for those ideals which we know to be right, when we become hard enough to refuse to aid nations which do not permit self-determination, when we become strong enough to resist any more drifts towards socialism in our own Nation, when we recognize that our enemy is Communism not war, and when we realize that concessions to Communists do not insure peace or freedom, then, and only then will we no longer be `` soft ''.

The weekly loss is partly counterbalanced by 500 arrivals each week from West Germany, but the hard truth, says Crossman, is that `` The closing off of East Berlin without interference from the West and with the use only of East German, as distinct from Russian, troops was a major Communist victory, which dealt West Berlin a deadly, possibly a fatal, blow.

Berlin's resilience is amazing, but if it has to hire its labor in the West the struggle will be hard indeed ''.

It is, I insist, hard to define the Rayburn contribution to our political civilization because it is so massive and so widespread and so complicated, and because it goes so deep.

It is a flavor that might take a little getting used to -- not because it is unpleasant, but because the flavor is hard to define in the light of our experience with other fruits.

Aeschbacher's work is very much akin to Schnabel's, but the sound on his Decca disc is dated, and you will have a hard time locating a copy of it.

This design is hard to beat for timber hunting or for packing in a saddle scabbard.

Paperweight may be personalized on back while clay is leather hard.

Although there is no question but that the process of washing fabrics involves a number of phenomena which are related together in an extremely complicated way and that these phenomena and their interrelations are not well understood at the present, this section attempts to present briefly an up-to-date picture of the physical chemistry of washing either fabrics or hard surfaces.

It is hard to understand how he concluded that most snakes do not grow appreciably after attaining maturity ; ;

Particularly hard for the therapist to grasp are those instances in which the patient is manifesting an introject traceable to something in the therapist, some aspect of the therapist of which the latter is himself only poorly aware, and the recognition of which, as a part of himself, he finds distinctly unwelcome.

The Secretary of the Interior or any duly authorized representative shall be entitled to admission to, and to require reports from the operator of, any metal or nonmetallic mine which is in a State ( excluding any coal or lignite mine ), the products of which regularly enter commerce or the operations of which substantially affect commerce, for the purpose of gathering data and information necessary for the study authorized in the first section of this Act.

Another recent achievement was the successful development of a method for the complete combustion in a bomb calorimeter of a metal in fluorine when the product is relatively non-volatile.

Even here there is room for some variation, for metal surfaces vary in smoothness, absorptive capacity, and chemical reactivity.

Each teacher has in his classroom a metal file, equipped with a lock, which is used to store cumulative record folders.

Preparation of a coordination compound is often accomplished by the simple method of reacting a metal salt with a ligand in a suitable solvent such as an alcohol.

Particular interest is directed towards the condensation of these ligands with metal halides to form substituted phosphide or arside complexes.

Make sure that the metal tube through which the wire passes is in the shape of an inverted `` L '', the foot of the `` L '' about three inches long, so that the puppet can hang directly under the light.

In the modern IUPAC nomenclature, the alkali metals comprise the group 1 elements, excluding hydrogen ( H ), which is nominally a group 1 element but not normally considered to be an alkali metal as it rarely exhibits behaviour comparable to that of the alkali metals.

Experiments have been conducted to attempt the synthesis of ununennium ( Uue ), which is likely to be the next member of the group, but they have all met with failure .< ref name =" link "> However, ununennium may not be an alkali metal due to relativistic effects, which are predicted to have a large influence on the chemical properties of superheavy elements.

Metallic antimony is a brittle, silver-white shiny metal.

Americium is a relatively soft radioactive metal with silvery appearance.

Astatine is sometimes described as being a black solid ( assuming that it follows this trend ), or as having a metallic appearance ( if it is a metalloid or a metal ).

Steel is a metal alloy whose major component is iron, with carbon content between 0. 02 % and 2. 14 % by mass.

Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties.

The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal.

The primary metal is called the base, the matrix, or the solvent.

When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism.

With the interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully replace an atom in the crystals of the base metal.

These defects are created during plastic deformation, such as hammering or bending, and are permanent unless the metal is recrystallized.

While the use of iron started to become more widespread around 1200 BC, mainly because of interruptions in the trade routes for tin, the metal is much softer than bronze.
