For example, there are persons who are in physical science, in the field of mineralogy, trained in crystallography, who use only X-rays, applying only the powder technique of X-ray diffraction, to clay minerals only, and who have spent the last fifteen years concentrating on the montmorillonites ; ;

* Aura analysis – a technique in which supporters of the method claim that the body's aura, or energy field is analyzed

This technique is the most widespread method of computing amplitudes in quantum field theory today.

One technique used to reach very low temperatures ( thousandths and even millionths of a degree above absolute zero ) is adiabatic demagnetisation, where the change in magnetic field on a magnetic material is used to provide adiabatic cooling.

The advantage of this technique is that total and background absorption are measured with the same emission profile of the same lamp, so that any kind of background, including background with fine structure can be corrected accurately, unless the molecule responsible for the background is also affected by the magnetic field ; the disadvantage is the increased complexity of the spectrometer.

Field ion microscopy techniques were initially construed as a modification of field emission, a technique which allows for a stream of electrons to be emitted from a sharp needle when subjected to a sufficiently high electric field (~ 3-6 V / nm ).

The delayed steal is a deceptive technique that is sometimes executed by even slow runners and many times results in a catcher throwing into center field.

The Ganzfeld ( German for " whole field ") is a technique used to test individuals for telepathy.

Psychometrics is the field of study concerned with the theory and technique of psychological measurement, which includes the measurement of knowledge, abilities, attitudes, personality traits, and educational measurement.

The discovery of asymptotic freedom in the strong interactions by David Gross, David Politzer and Frank Wilczek allowed physicists to make precise predictions of the results of many high energy experiments using the quantum field theory technique of perturbation theory.

Where, for ordinary field theories such as quantum electrodynamics, a technique known as renormalization is an integral part of deriving predictions which take into account higher-energy contributions, gravity turns out to be nonrenormalizable: at high energies, applying the recipes of ordinary quantum field theory yields models that are devoid of all predictive power.

Some early attempts were often no more than a field gun or anti-tank gun mounted on a truck-a technique known in the British Army as carrying portee.

Yet GUTs are clearly not the final answer ; both the current standard model and all proposed GUTs are quantum field theories which require the problematic technique of renormalization to yield sensible answers.

This technique is used to confine very hot plasmas with temperatures of the order of 10 < sup > 6 </ sup > K. In a similar way, the Earth's non-uniform magnetic field traps charged particles coming from the sun in doughnut shaped regions around the earth called the " Van Allen radiation belts ", which were discovered in 1958 using data obtained by instruments aboard the Explorer 1 satellite.

This technique is called supervisor mode ; compared to more crude approaches ( such as storing the TCB in ROM, or equivalently, using the Harvard architecture ), it has the advantage of allowing the security-critical software to be upgraded in the field, although allowing secure upgrades of the trusted computing base poses bootstrap problems of its own.

The authors of the study interpreted this as being the result of the ease by which primary commodities may be extorted or captured compared to other forms of wealth, for example, it is easy to capture and control the output of a gold mine or oil field compared to a sector of garment manufacturing or hospitality services.

The coat of arms of the Kingdom of Jerusalem, which has gone through several different varieties of a cross Or ( gold ) on an argent ( silver ) field, is a famous violation of or exception to the rule of tincture in heraldry, which prohibits the placement of metal on metal.

It has been conjectured that the golden spheres were originally three flat yellow effigies of byzants, or gold coins, laid heraldically upon a sable field, but that they were converted into spheres to better attract attention.

Nurmi's record for most Olympic gold medals was matched by gymnast Larisa Latynina in 1964, swimmer Mark Spitz in 1972 and fellow track and field athlete Carl Lewis in 1996, and broken by swimmer Michael Phelps in 2008.

The first flag of the republic was the " Burnet Flag " ( a gold star on an azure field ), followed shortly thereafter by official adoption of the Lone Star Flag.

In the 1960 Summer Olympics in Rome Rudolph became the first American woman to win three gold medals in track and field during a single Olympic Games.

In July 2009, the Staffordshire Hoard of Anglo-Saxon gold was discovered in a field near Lichfield in Staffordshire.

However, when, in 1886, a major gold field was discovered at an outcrop on a large ridge some sixty kilometres south of the Boer capital at Pretoria, it reignited British imperial interests.

Several successful professional athletes hail from Montgomery, including Pro Football Hall of Famer Bart Starr and two-time Olympic gold medalist in track and field Alonzo Babers.

Insignia of rank are worn on the jacket lapel of the dress uniform ( silver stars on a green or gold shield ) and on the epaulets of the field uniform ( white, silver or gold stars on a olive drab field ).

As of 2007, no other track and field athlete has won more gold medals in a single Olympics, although Alvin Kraenzlein ( 1900 ), Jesse Owens ( 1936 ) and Carl Lewis ( 1984 ) have also won four gold medals in one Olympics.

She is one of only four women to have won four gold medals in track and field Olympic history.
