The appointment of U Thant of Burma as the U.N.'s Acting Secretary General -- at this writing, the choice appears to be certain -- offers further proof that in politics it is more important to have no influential enemies than to have influential friends.

With the neutralists maintaining pressure for one of their own to succeed Mr. Hammarskjold, U Thant emerged as the only possible candidate unlikely to be waylaid by a veto.

U Thant of course, will hold office until the spring of 1963, when Mr. Hammarskjold's term would have come to an end.

the West may or not remain satisfied with the kind of neutralism that U Thant represents.

If Af are the projections associated with the primary decomposition of T, then each Af is a polynomial in T, and accordingly if a linear operator U commutes with T then U commutes with each of the Af, i.e., each subspace Af is invariant under U.

Near Q, both curves can be represented by analytic functions of U.

In a neighborhood of Q the difference between these functions is also a single-valued, analytic function of U.

The restrained gyro-stabilized platform with reasonable response characteristics operates with an approximate equation of motion, neglecting transient effects, as follows: Af where U is a torque applied about the output axis of the controlling gyro.

Lincoln's assassination was the first assassination of a U. S. president and sent the nation into mourning.

Lincoln has been consistently ranked by scholars and the public as one of the three greatest U. S. presidents.

In 1846, Lincoln was elected to the U. S. House of Representatives, where he served one two-year term.

Lincoln also supported the Wilmot Proviso, which, if it had been adopted, would have banned slavery in any U. S. territory won from Mexico.

Lincoln disapproved of slavery, and the spread of slavery to new U. S. territory in the west.

Douglas ' provision, which Lincoln opposed, specified settlers had the right to determine locally whether to allow slavery in new U. S. territory, rather than have such a decision restricted by the national Congress.

In late 1854, Lincoln ran as a Whig for the U. S. Senate seat from Illinois.

After the state Republican party convention nominated him for the U. S. Senate in 1858, Lincoln delivered his House Divided Speech, drawing on: " A house divided against itself cannot stand.

The stage was then set for the campaign for statewide election of the Illinois legislature which would, in turn, select Lincoln or Douglas as its U. S. senator.

Douglas said that Lincoln was defying the authority of the U. S. Supreme Court and the Dred Scott decision.

The U. S. Navy illegally intercepted a British merchant ship the Trent on the high seas and seized two Confederate envoys ; Britain protested vehemently while the U. S. cheered.

He argued before and during his election that the eventual extinction of slavery would result from preventing its expansion into new U. S. territory.

Anthropologists ' involvement with the U. S. government, in particular, has caused bitter controversy within the discipline.

Austin is the capital of the U. S. state of Texas.

The land went through several administrative changes before becoming an organized ( or incorporated ) territory on May 11, 1912, and the 49th state of the U. S. on January 3, 1959.

In the U. S. federal court system, criminal defendants must file a notice of appeal within 10 days of the entry of either the judgment or the order being appealed, or the right to appeal is forfeited.

Many U. S. jurisdictions title their appellate court a court of appeal or court of appeals.

This reaction was first studied in 2006 at the LBNL as part of their systematic study of fusion reactions using < sup > 238 </ sup > U targets.

This process is calculated within enthalpy calculations as U + pV, to label the amount of energy or work required to " set aside space for " and " create " the system ; describing the work done by both the reaction or formation of systems, and the surroundings.

Thereafter, statements were made suggesting a future confrontation with the West, calling the United States both a " fascizing " power and the " center of worldwide reaction and anti-Soviet activity ," with all U. S .- aligned countries branded as enemies.

In 2002 – 2003, the team at LBNL attempted to generate the isotope < sup > 271 </ sup > Mt to study the chemical properties by bombarding uranium-238 with chlorine-37, but without success .< ref name = GSI2003 >" The search for < sup > 271 </ sup > Mt via the reaction < sup > 238 </ sup > U + < sup > 37 </ sup > Cl ", Zielinski et al .., GSI Annual report, 2003.

" U. S. legislators, including Senate Majority Leader Harry Reid, also condemned both the burning and the violence in reaction to it.

*< sup > 237 </ sup > U is also produced via an ( n, 2n ) reaction with < sup > 238 </ sup > U. This only happens with very energetic neutrons.

A few particularly fissile and readily obtainable isotopes ( notably < sup > 235 </ sup > U and < sup > 239 </ sup > Pu ) are called nuclear fuels because they can sustain a chain reaction and can be obtained in large enough quantities to be useful.

However, too few of the neutrons produced by < sup > 238 </ sup > U fission are energetic enough to induce further fissions in < sup > 238 </ sup > U, so no chain reaction is possible with this isotope.

The specific nuclear reaction may be the fission of heavy isotopes ( e. g. < sup > 235 </ sup > U ) or the fusion of light isotopes ( e. g. < sup > 2 </ sup > H and < sup > 3 </ sup > H ).

Following the 11 September 2001 attacks in the United States, perpetrated mostly by Saudi nationals, Prince Nayef was strongly criticized by the U. S. for his reaction.

However, public reaction to the Sputnik crisis led to the creation of the Advanced Research Projects Agency ( renamed the Defense Advanced Research Projects Agency or DARPA in 1972 ), NASA, and an increase in U. S. government spending on scientific research and education.

In a breeder reactor, uranium-238 can also be converted into plutonium through the following reaction: < sup > 238 </ sup > U ( n, gamma ) → < sup > 239 </ sup > U -( beta ) → < sup > 239 </ sup > Np -( beta ) → < sup > 239 </ sup > Pu.

* December 2 – Manhattan Project: Below the bleachers of Stagg Field at the University of Chicago, a team led by Enrico Fermi initiates the first self-sustaining nuclear chain reaction ( a coded message, " The Italian navigator has landed in the new world " is then sent to U.

The Palmer Raids occurred in the larger context of the Red Scare, the term given to fear of and reaction against political radicals in the U. S. in the years immediately following World War I.

The presence of too much of the < sup > 238 </ sup > U isotope inhibits the runaway nuclear chain reaction that is responsible for the weapon's power.

The phrase was coined in adverse reaction to something Murphy said when his devices failed to perform and was eventually cast into its present form prior to a press conference some months later — the first ever ( of many ) conferences given by Dr. John Stapp, a U. S. Air Force colonel and Flight Surgeon in the 1950s.

In the West, the reaction to Russia's handling of, or perhaps interference in, the Ukrainian election evoked echoes of the Cold War, but relations with the U. S. have remained stable.

Provocative action against North Vietnam was considered after the August, 1964 incidents John McNaughton suggested in September 1964 that the U. S. prepare to take actions to provoke a North Vietnamese military reaction, including plans to use DESOTO patrols North.

The first experiments were conducted using the < sup > 238 </ sup > U (< sup > 48 </ sup > Ca, 3n )< sup > 283 </ sup > Cn reaction.

During " Commando Hunt IV " ( 30 April through 9 October 1971 ), U. S., South Vietnamese, and Laotian forces began to feel the North Vietnamese reaction to General Lon Nol's coup in Cambodia and the subsequent closure of the port of Sihanoukville to its supply shipments.
