Most Papua New Guineans still adhere strongly to this traditional social structure, which has its roots in village life.

-more than 20 in all, can be precisely calculated from chemical structure, even if such chemical molecule is still non existent ), and in this area is concentrated practical importance of contemporary physical chemistry.

Pausanias ( 2nd century AD ) mentions two buildings resembling pyramids, one, 19 kilometres ( 12 mi ) southwest of the still standing structure at Hellenikon, a common tomb for soldiers who died in a legendary struggle for the throne of Argos and another which he was told was the tomb of Argives killed in a battle around 669 / 8 BC.

At the end of this period a new landscape emerges: the northern Canaanite cities still existed, more or less intact, and became the Phoenicians ; the highlands behind the coastal plains, previously largely uninhabited, were rapidly filling with villages, largely Canaanite in their basic culture but without the Bronze Age city-state structure ; and along the southern coastal plain there are clear signs that a non-Canaanite people had taken over the former Canaanite cities while adopting almost all aspects of Canaanite culture.

Foucault's author function is the idea that an author exists only as a function of a written work, a part of its structure, but not necessarily part of the interpretive process.

In the nuclear chromosomes of eukaryotes, the uncondensed DNA exists in a semi-ordered structure, where it is wrapped around histones ( structural proteins ), forming a composite material called chromatin.

# Psychological maladjustment exists when the organism denies awareness of significant sensory and visceral experiences, which consequently are not symbolized and organized into the gestalt of the self structure.

A geological structure exists in the sea floor off the west coast of India that has been suggested as a possible impact crater, in this context called the Shiva crater.

DNA usually exists as a double-stranded structure, with both strands coiled together to form the characteristic double-helix.

Generally, the structure of a glass exists in a metastable state with respect to its crystalline form, although in certain circumstances, for example in atactic polymers, there is no crystalline analogue of the amorphous phase.

The answer to this question turned out to be negative: in 1952, Gleason, Montgomery and Zippin showed that if G is a topological manifold with continuous group operations, then there exists exactly one analytic structure on G which turns it into a Lie group ( see also Hilbert – Smith conjecture ).

The exponential map and the Lie algebra determine the local group structure of every connected Lie group, because of the Baker – Campbell – Hausdorff formula: there exists a neighborhood U of the zero element of, such that for u, v in U we have

Order function: This function treats its input as a structure, and finds the next index that exists which has the same structure except for the last subscript.

Neodymium exists in two allotropic forms, with a transformation from a double hexagonal to a body-centered cubic structure taking place at about 863 ° C.

But Jean Piaget, who would better define himself as constructivist, considers structuralism as " a method and not a doctrine " because for him " there exists no structure without a construction, abstract or genetic "

Thorium is dimorphic, changing at 1360 ° C from a face-centered cubic to a body-centered cubic structure ; a body-centered tetragonal lattice form exists at high pressure with impurities driving the exact transition temperatures and pressures.

X-Ray diffraction studies on the hydrogen urate ion in crystals of ammomium hydrogen urate, formed in vivo as gouty deposits, reveal the keto-oxygen in the 2 position of a tautomer of the purine structure exists as a hydroxyl group and the two flanking nitrogen atoms at the 1 and 3 positions share the ionic charge in the six membered pi-resonance-stabilized ring.

Voluntary unemployment is attributed to the individual's decisions, whereas involuntary unemployment exists because of the socio-economic environment ( including the market structure, government intervention, and the level of aggregate demand ) in which individuals operate.

The beta allotrope exists at room temperature, and it has a face-centered cubic crystal structure.

The advantages of the Alexandroff compactification lie in its simple, often geometrically meaningful structure and the fact that it is in a precise sense minimal among all compactifications ; the disadvantage lies in the fact that it only gives a Hausdorff compactification on the class of locally compact, noncompact Hausdorff spaces, unlike the Stone – Čech compactification which exists for any Tychonoff space, a much larger class of spaces.
