Communities are nested ; one community can contain another — for example a geographic community may contain a number of ethnic communities.

A second canonical example is two different kinds of matching nested parentheses, described by the productions:

The variable ^ Car (" Door ") could have a nested variable subscript of " Color " for example.

For example, the ordered triple ( a, b, c ) can be defined as ( a, ( b, c )), i. e., as one pair nested in another.

An example is a coffee-cup calorimeter, which is constructed from two nested Styrofoam cups and a lid with two holes, allowing insertion of a thermometer and a stirring rod.

A particularly ingenious example of nested narratives is James Merrill's 1974 modernist poem " Lost in Translation ".

This could be confusing to programmers accustomed to unique addressing schemes, but it can also be used to advantage, for example when addressing multiple nested data structures.

Often nested models are run forced by the global models for boundary conditions, to achieve higher local resolution: for example, the Met Office runs a mesoscale model with an resolution covering the UK, and various agencies in the U. S. also run nested models such as the NGM and NAM models.

For example, the quicksort algorithm can be implemented so that it never requires more than nested recursive calls to sort items.

For the purposes of the List example, these two formulations are not significantly different ; but the second form allows one to express so-called nested data types, i. e., those where the recursive type differs parametrically from the original.

It is thus possible to take many routes through this typology, with, for example, an exploratory, theory-building, multiple, nested study, or an evaluative, theory-testing, single, retrospective study.

The paradigmatic example of a nested metalanguage comes from the Linnean taxonomic system in biology.

For example, an ultrapower model of the hyperreals is-saturated, meaning that every descending nested sequence of internal sets has a nonempty intersection, see Goldblatt ( 1998 ).

This is a significant difference in many domains: for example, hand-written source code has an effectively constant expression nesting depth independent of the length of the program — expressions nested beyond a certain depth tend to get refactored.

An example of C code involving nested for loops, where the loop counter variables are i and j:

For example: cage-free, free-running, free-roaming, naturally nested, etc.

Where the particle consists of nested spheres-the most common example of which is the approximation of a spherical cell composed of an inner part ( the cytoplasm ) surrounded by an outer layer ( the cell membrane )-then this can be represented by nested expressions for the shells and the way in which they interact, allowing the properties to be elucidated where there are sufficient parameters related to the number of unknowns being sought.

For example, if a player has lines of nested " Z " pieces, and then drops another " Z " directly on top of one of the nested " Z " s, the one which was dropped will cause the piece below to implode, in turn causing all identical pieces touching that piece to explode, and so on.

For example, this small pseudo-code program uses two nested loops to iterate over all the entries of an n × n matrix, changing their values so that the matrix becomes an identity matrix:

For example, the executions of a statement nested inside an outer loop with index i and an inner loop with index j can be associated with the pairs of integers ( i, j ).

A TOTE can also be nested within other TOTEs, for example:

Although biopsies have shown structural changes in some of the reported cases of steroid-induced weakness, this case provides the only example known to us in which necropsy afforded the opportunity for extensive study of multiple muscle groups.

For example, the level of improvement noted in a recent experiment with a short course of immediate treatment for parent-child relationship problems compared favorably with the results reported by typical child guidance clinics where the hours spent in purely diagnostic study may equal or exceed the number of hours devoted to actual treatment interviews in the experimental project.

For example, the steering committee might announce that the group felt a topic under study should not be dropped for an additional week as there was still too much of it untouched.

For example, he cites the following data from two studies on job satisfaction: in the first study, 85 per cent of professionals and executives, 64 per cent of white collar people, and 41 per cent of factory workers expressed satisfaction with their jobs ; ;

For example, one study on volunteerism found that feeling overwhelmed by others ' demands had an even stronger negative effect on mental health than helping had a positive one ( although positive effects were still significant ).

For example, in some groups, the group operation is commutative, and this can be asserted with the introduction of an additional axiom, but without this axiom we can do quite well developing ( the more general ) group theory, and we can even take its negation as an axiom for the study of non-commutative groups.

Thus for example Heraclitus ' The Allegorist ' quoted fr. 326 and part of fr. 6, about ships in a storm, in his study on Homer's use of allegory.

This method can be used for example for further study of enamel and dentin of human teeth and bones.

Although it has been known for a while that the Black Sea and the Sea of Marmara flow into each other in an example of a density flow, findings of a study by the University of Leeds in August 2010 reveal that there is in fact an underwater channel of high density water flowing across the floor of the Bosphorus ( caused by the difference in density of the two seas ), which would be the sixth largest river on Earth if it were to be on land.

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.

For example, promoter analysis involves the identification and study of sequence motifs in the DNA surrounding the coding region of a gene.

For example, programming language theory studies approaches to description of computations, while the study of computer programming itself investigates various aspects of the use of programming languages and complex systems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans.

Another example is the word (" study, learn ").

For example, programming language theory considers various approaches to the description of computation, whilst the study of computer programming itself investigates various aspects of the use of programming language and complex systems.

Laser spectroscopy is used as a tool for studying phenomena with energy in the range of visible light, for example, to study non-linear optics and forbidden transitions in media.

For example, Philippe Bourgois won the Margaret Mead Award in 1997 for In Search of Respect, a study of the entrepreneurs in a Harlem crack-den.

For example, the study found that people who believe Osama Bin Laden was captured alive by Americans are likely to also believe that Bin Laden was actually killed prior to the 2011 raid.

Some questions in the study of visual perception, for example, include: ( 1 ) How are we able to recognize objects ?, ( 2 ) Why do we perceive a continuous visual environment, even though we only see small bits of it at any one time?

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.

This is still a very active field of study, with scientists seeking both better data ( for example, the Planck spacecraft ) and better interpretations of the initial conditions of expansion.

Parapsychology, including the study of clairvoyance, is an example of pseudoscience.

For example, philosopher John D. Kenyon writes: Reason might manage to raise a doubt about the truth of a conclusion of natural inductive inference just for a moment in the study, but the forces of nature will soon overcome that artificial skepticism, and the sheer agreeableness of animal faith will protect us from excessive caution and sterile suspension of belief.

For example in a paper reporting on a study involving human subjects, there typically appears a table giving the overall sample size, sample sizes in important subgroups ( e. g., for each treatment or exposure group ), and demographic or clinical characteristics such as the average age, the proportion of subjects of each sex, and the proportion of subjects with related comorbidities.

For example, it might study what constitutes upbringing and education, the values and norms revealed through upbringing and educational practices, the limits and legitimization of education as an academic discipline, and the relation between education theory and practice.

The sub-disciplines can overlap, for example, in the growth of power electronics, and the study of behavior of large electrical grids.
