Some evolutionary psychologists apply the same thinking to psychology, arguing that the mind has a modular structure similar to that of the body, with different modular adaptations serving different functions.

It is important to note that a particular Euclidean function f is not part of the structure of a Euclidean domain: in general, a Euclidean domain will admit many different Euclidean functions.

Modern paleontology has joined with evolutionary biology to share the interdisciplinary task of unfolding the tree of life, which inevitably leads backwards in time to the microscopic life of the Precambrian when cell structure and functions evolved.

Language features include structured programming, reflection ( the ability to modify the program structure during program execution ), concatenative programming ( functions are composed with juxtaposition ) and extensibility ( the programmer can create new commands ).

However, they can be managed in ways that enhance their biodiversity protection functions and they are important providers of ecosystem services such as maintaining nutrient capital, protecting watersheds and soil structure as well as storing carbon.

In RRG, the description of a sentence in a particular language is formulated in terms of its semantic structure and communicative functions, as well as the grammatical procedures used to express these meanings.

In general, functional decompositions are worthwhile when there is a certain " sparseness " in the dependency structure ; that is, when constituent functions are found to depend on approximately disjoint sets of variables.

The purpose of defining a group homomorphism as it is, is to create functions that preserve the algebraic structure.

The structure of the N-and C-terminal tails of GPCRs may also serve important functions beyond ligand-binding.

Because abstract algebra studies sets endowed with operations that generate interesting structure or properties on the set, functions which preserve the operations are especially important.

Hash functions are an essential ingredient of the Bloom filter, a compact data structure that provides an enclosing approximation to a set of them.

Confirmation and clarity came a year later in 1953, when James D. Watson and Francis Crick correctly hypothesized, in their journal article " Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid ", the double helix structure of DNA, and suggested the copying mechanism by which DNA functions as hereditary material.

The new structure would be located to the east of the original building, and tasked with two functions: offer a large space for public appreciation of various popular collections ; and house office space as well as archives for scholarship and research.

Human language is unique among the lifeforms of Earth because its complex structure affords a much wider range of possible expressions and uses than any known system of animal communication, all of which are generally closed systems, with limited functions and mostly genetically rather than socially transmitted.

These are not, however, differences in federal structure.

For this concept of an Advisory Board, ancillary to the Board of Trustees, we are indebted to the late President of Harvard University, A. Lawrence Lowell, a master of the subject of the structure of cultural institutions and their administration.

Whereas the usual organic surface-active agent is strongly sorbed at oil - water interfaces, the highly charged ions are most strongly sorbed at interfaces between water and insoluble materials exhibiting an ionic structure ( see Table 26-2 on p. 1678 ).

However, it cannot be presumed, informal though the structure of the population seems, that there are not well-defined roles within the system.

Holding the final corporation entitled to sue on the claim, the Court cited the Seaboard, Novo Trading, and Roomberg cases for the proposition that `` transfers by operation of law or in conjunction with changes of corporate structure are not assignments prohibited by the statute ''.

Naturally, enterprises of the size of General Electric are in a position to structure their prices in such a way that the relatively small competitors can be forced to the wall in a very short time.

These balls are moving in great circles and ellipses, and are of course, the electrons, the particles of negative electricity which by their action create the forces that tie this atom of calcium to the neighboring atoms of oxygen and make up the solid structure of my finger bone.

And so today when we examine the structure of our knowledge of the atom and of the universe, we are forced to conclude that the best word to describe our universe is music.

Alkanes ( also known as paraffins or saturated hydrocarbons ) are chemical compounds that consist only of hydrogen and carbon atoms and are bonded exclusively by single bonds ( i. e., they are saturated compounds ) without any cycles ( or loops ; i. e., cyclic structure ).

* linear ( general formula ) wherein the carbon atoms are joined in a snake-like structure

* Cal-Earth ( The California Institute of Earth Art and Architecture ) has developed a patented system called Superadobe, in which bags filled with stabilized earth are layered with strands of barbed wire to form a structure strong enough to withstand earthquakes, fire and flood.

Korzybski's work maintained that human beings are limited in what they know by ( 1 ) the structure of their nervous systems, and ( 2 ) the structure of their languages.

In the Standard Model of physics, electrons are truly elementary particles with no internal structure.
