For an example of its use, analysis of the concentration of elements is important in managing a nuclear reactor, so nuclear scientists will analyze neutron activation to develop discrete measurements within vast samples.

However, many important and interesting operations are non-associative ; one common example would be the vector cross product.

Another important example is the Tawagalawa Letter written by an unnamed Hittite king ( most probably Hattusili III ) of the empire period ( 14th-13th century BC ) to the king of Ahhiyawa, treating him as an equal and suggesting that Miletus ( Millawanda ) was under his control.

Another example is that body symmetry is an important aspect of physical attractiveness which may be due to this indicating good health during body growth.

This accompanied or facilitated other important evolutionary developments: the bilaterian body plan ; the coelom, an internal cavity that provided space for a circulatory system and, in some animals, formed a hydrostatic skeleton which enables worm-like animals to burrow ; metamerism, in which the body was built of repeated " modules " which could later specialize, for example the heads of most arthropods are composed of fused, specialized segments.

An important facet of The Settlers of Catan, for example, is convincing people to trade with you rather than with other players.

Politically, tourism is the more important of the two, as it employs a greater number of people within the Territory, and a larger proportion of the businesses in the tourist industry are locally owned, as are a number of the highly tourism-dependent sole traders ( for example, taxi drivers and street vendors ).

Glucose, one of the most important carbohydrates, is an example of a monosaccharide.

As an example, the important blood serum protein albumin contains 585 amino acid residues.

Eventually the head or " monarchic " bishop came to rule more clearly, and all local churches would eventually follow the example of the other churches and structure themselves after the model of the others with the one bishop in clearer charge, though the role of the body of priests remained important.

Botanists also study how plants produce food we can eat and how to increase yields and therefore their work is important in mankind's ability to feed the world and provide food security for future generations, for example, through plant breeding.

) Base stacking effects are especially important in the secondary structure and tertiary structure of RNA ; for example, RNA stem-loop structures are stabilized by base stacking in the loop region.

For example, drought and excessively salty soil are two important limiting factors in crop productivity.

Self-adjoint operators, where A = A < sup >†</ sup >, play an important role in quantum mechanics ; for example, an observable is always described by a self-adjoint operator.

An important example of such an algebra is a commutative C *- algebra.

As an example, in British Columbia the forestry industry is of great importance, while the oil and gas industry is important in Alberta, Saskatchewan and Newfoundland and Labrador.

To consider but one example, the First Amendment to the United States Constitution states " Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof "— but interpretation ( that is, determining the fine boundaries, and resolving the tension between the " establishment " and " free exercise " clauses ) of each of the important terms was delegated by Article III of the Constitution to the judicial branch, so that the current legal boundaries of the Constitutional text can only be determined by consulting the common law.

Condensed matter physics also has important applications to Biophysics, for example, the experimental technique of magnetic resonance imaging, which is widely used in medical diagnosis.

The per capita income of the CAR is often listed as being around $ 300 a year, said to be one of the lowest in the world, but this figure is based mostly on reported sales of exports and largely ignores the more important but unregistered sale of foods, locally-produced alcohol, diamonds, ivory, bushmeat, and traditional medicines, for example.

For example, he or she cannot veto the legislative budget, and thus Congress is sovereign over the year's single most important piece of legislation.

These shales are an important source rock for oil and gas, for example in the subsurface of the North Sea.

Another example is the place of The Wizard of Oz ( 1939 ) in American and British gay culture, although a widely viewed and historically important film in greater American culture.

They are important in military engineering, and are also used to carry traffic while an old bridge is being rebuilt.

Its principles are especially important in chemical engineering.

By the early 1920s, unit operations became an important aspect of chemical engineering at MIT and other US universities, as well as at Imperial College London.

Although feedback is an important aspect of control engineering, control engineers may also work on the control of systems without feedback.

* The Defense Sciences Office ( DSO ) vigorously pursues the most promising technologies within a broad spectrum of the science and engineering research communities and develops those technologies into important, radically new military capabilities.

Perhaps the most important technical skills for electrical engineers are reflected in university programs, which emphasize strong numerical skills, computer literacy and the ability to understand the technical language and concepts that relate to electrical engineering.

Most engineering projects involve some form of documentation and strong written communication skills are therefore very important.

Eiffel's most important contribution to software engineering is design by contract ( DbC ), in which assertions, preconditions, postconditions, and class invariants are employed to help ensure program correctness without sacrificing efficiency.

In 2000 the United States Congress designated the Erie Canalway National Heritage Corridor to recognize the national significance of the canal system as the most successful and influential human-built waterway and one of the most important works of civil engineering and construction in North America.

The discovery of the ELIZA effect was an important development in artificial intelligence, demonstrating the principle of using social engineering rather than explicit programming to pass a Turing test.

By 2005, Richard Glass considered the differences to be a " serious fracture " but " vitally important to those on both sides of the fracture " and " of little importance to anyone else studying the movement from a software engineering perspective " since they have had " little effect on the field ".

* Filtration is also important and widely used as one of the unit operations of chemical engineering.

In modern times, geology is commercially important for mineral and hydrocarbon exploration and for evaluating water resources ; it is publicly important for the prediction and understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change ; plays a role in geotechnical engineering ; and is a major academic discipline.

After his retirement from engineering, Eiffel concentrated his energies on research into meteorology and aerodynamics, making important contributions in both fields.

Eiffel went on to attend the Collège Sainte-Barbe in Paris, in order to prepare for the difficult entrance exams set by the most important engineering colleges in France.

Geotechnical engineering is important in civil engineering, but is also used by military, mining, petroleum, or any other engineering concerned with construction on or in the ground.

Easton's firm, inherited by his son James ( 1796 – 1871 ), grew during the nineteenth century to become one of the more important engineering manufacturers in the United Kingdom, with a large works at Erith, Kent.

In the post – World War I euphoria, the idea of a ' makeable society ' was an important catalyst behind the social engineering of the ILO architects.

The state is an important source of engineering job opportunities.

It is also an important part of forensic engineering and failure analysis.

These materials are ideal for situations where high strength-to-weight ratios are more important than bulk cost, such as in the aerospace industry and certain automotive engineering applications.

The field is a major academic discipline, and is also important for mineral and hydrocarbon extraction, knowledge about and mitigation of natural hazards, some Geotechnical engineering fields, and understanding past climates and environments.
