There are complications, and the technique requires careful preparation and a level of skill and experience above that required for a single anchor.

The advantage of this technique is that only a medium-resolution monochromator is necessary for measuring AAS ; however, it has the disadvantage that usually a separate lamp is required for each element that has to be determined.

Obviously, a high-resolution monochromator is required for this technique, as will be discussed later.

The technique required varies depending on the specimen and the analysis required:

In the construction and maintenance of the system there are two other roles: the problem domain expert who builds the system and supplies the knowledge base, and a knowledge engineer who assists the experts in determining the representation of their knowledge, enters this knowledge into an explanation module and who defines the inference technique required to solve the problem.

By using the technique called the molecular clock which estimates the time required for the number of divergent mutations to accumulate between two lineages, the approximate date for the split between lineages can be calculated.

A popular variation is the nutrient film technique or NFT, whereby a very shallow stream of water containing all the dissolved nutrients required for plant growth is recirculated past the bare roots of plants in a watertight thick root mat, which develops in the bottom of the channel, has an upper surface that, although moist, is in the air.

The study of human problem solving required new kinds of human measurements and, with Anders Ericsson, Simon developed the experimental technique of verbal protocol analysis.

* Microwave assisted firing-this technique combine microwave energy with more conventional energy sources such as radiant gas or electric heating in order to process ceramic materials to the required high temperatures.

Finally, it required a stable viewing platform, rendering the technique useless on the rolling deck of a ship at sea.

To represent a film wider than 16: 9 ( e. g., a 2. 35: 1 film ) on a 16: 9 display with no cropping, both anamorphic and letterbox techniques ( or letterboxing alone ) are required ; using the anamorphic technique, the mattes will be smaller but still necessary.

The simplicity of the technique and the minimal sample preparation required are significant advantages.

The Penicillium cells are grown using a technique called fed-batch culture, in which the cells are constantly subject to stress, which is required for induction of penicillin production.

Shooting technique differs depending on factors like the type of firearm used ( from a handgun to a sniper rifle ), the distance to and nature of the target, the required precision and the available time.

Using this technique, a small number of triodes could be made to do the work that formerly required dozens of triodes.

This collaborative technique builds greater insight into scope definitions, underlying assumptions, and consensus regarding the level of granularity required to manage the project.

Modern downhill technique is generally a combination of carving and skidding, varying the ratio between the two when rapid control over the turn or speed is required.

Firestopping is a technique used in these cases, and it is required where mechanical penetrants traverse fire-resistance rated wall and floor assemblies, or membranes thereof.

* size and shape of the instrument and the technique required to hold the instrument ;

The German Mozart tenor tradition goes back to end of the 1920s when Mozart tenors started making use of Caruso's technique to achieve and improve the required dynamics and dramatic expressiveness.

A specialized technique called " meend " involves pulling the main melody string down over the bottom portion of the sitar's curved frets, with which the sitarist can achieve a seven semitone range of microtonal notes ( it should be noted, however, that because of the sitar's movable frets, sometimes a fret may be set to a microtone already, and no bending would be required ).

Deductions are taken for all errors made while on the beam, including lapses in control, balance checks ( i. e., wobbling or stumbling to maintain balance ), poor technique and execution, and failure to fulfill the required Code of Points elements.

Differential scanning calorimetry or DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature.

The useful suggestion of Professor David Hawkins which considers culture as a third stage in biological evolution fits quite beautifully then with our suggestion that science has provided us with a rather successful technique for building protective artificial environments.

And to do this requires first of all the kind of information about people which is provided by the scientists in industrial anthropology and consumer research, who, for example, tell Courtenay that three days is the `` optimum priming period for a closed social circuit to be triggered with a catalytic cue-phrase '' -- which means that an effective propaganda technique is to send an idea into circulation and then three days later reinforce or undermine it.

He could no longer build anything, whether a private residence in his Pennsylvania county or a church in Brazil, without it being obvious that he had done it, and while here and there he was taken to task for again developing the same airy technique, they were such fanciful and sometimes even playful buildings that the public felt assured by its sense of recognition after a time, a quality of authentic uniqueness about them, which, once established by an artist as his private vision, is no longer disputable as to its other values.

What with traders trading for so many different objectives, and what with there being so many unique and individualized market theories and trading techniques in use, and more coming into use all the time, it is hard to imagine how any particular theory or technique could acquire enough `` fans '' to invalidate itself.

Thus while his theory or technique may not be oversubscribed, it is commonplace for bullish and bearish positions to become temporarily over-subscribed.

Then, advised by the Architect of the Capitol, the Joint Committee for the Library, traditionally responsible for the works of art in the building, ordered the space cleared and painted in fresco, to show `` the Peace after the Civil War '', `` the Spanish-American War '', and `` the Birth of Aviation '', to match as nearly as feasible Brumidi's technique and composition.

Several companies also saw possibilities in using the technique for extruding or molding vinyl products with a slight cellular core that would reduce costs yet would not affect physical properties of the end product to any great extent.

The low cost and ease of fabrication of the dies for three-dimensional foam cutting plus the wide variety of shapes, dimensions, and contours that can be tailor-made to customer requirements has made the technique useful for producing case liners, materials handling containers, packaging and cushioning devices, and such novelties as soap dishes, toys, head rests, arch supports, and gas pedal covers.

Although this technique is simple and satisfactory, one practical difficulty does exist: the direction of true north must be known for each launch point.

Leningrad's Kirov Ballet, famous for classic purity of technique, begins its first U.S. tour in New York ( through Sept. 30 ).

Assuming ZF is consistent, Paul Cohen employed the technique of forcing, developed for this purpose, to show that the axiom of choice itself is not a theorem of ZF by constructing a much more complex model which satisfies ZF ¬ C ( ZF with the negation of AC added as axiom ) and thus showing that ZF ¬ C is consistent.

J. J. Thomson created a technique for separating atom types through his work on ionized gases, which subsequently led to the discovery of stable isotopes.

Amplitude modulation ( AM ) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave.

Kedging or warping is a technique for moving or turning a ship by using a relatively light anchor.

* Ajax framework, a framework for the Ajax technique

ASCII art is a graphic design technique that uses computers for presentation and consists of pictures pieced together from the 95 printable ( from a total of 128 ) characters defined by the ASCII Standard from 1963 and ASCII compliant character sets with proprietary extended characters ( beyond the 128 characters of standard 7-bit ASCII

* Simulated annealing, a technique for searching for a solution in a space otherwise too large for ordinary search methods to yield results

The Alexander technique has been shown to be helpful for people suffering from tension headaches, back pain, frozen shoulders, housemaid's knee, flat feet, tennis elbow, minor digestive problems, asthma, difficulties sleeping, clumsiness, irritability and lethargy.

He credited the technique with allowing him to pursue his passion for Shakespearean acting.
