If not " true " crannogs, small occupied islets ( often at least partially artificial in nature ) may be referred to as island duns, although rather confusingly, 22 islet-based sites are classified as ' proper ' crannogs due to the different interpretations of the inspectors or excavators who drew up field reports Canmore search for crannog in the Western Isles Hebridean island dwellings or crannogs were commonly built on both natural and artificial islets, usually reached by means of a stone causeway.

:" If I had stated ... the possibility of the introduction or origination of fresh species being a natural, in contradistinction to a miraculous process, I should have raised a host of prejudices against me, which are unfortunately opposed at every step to any philosopher who attempts to address the public on these mysterious subjects ".

If X is a topological space, there is a natural way of transforming X /~ into a topological space ; see quotient space for the details.

If m and n are natural numbers and f ( x ) is a smooth ( meaning: sufficiently often differentiable ) function defined for all real numbers x in the interval, then the integral

If G = GL < sub >*</ sub >( K ), then the set of natural numbers is a proper subset of G < sub > 0 </ sub >, since for each natural number n, there is a corresponding identity matrix of dimension n. G ( m, n ) is empty unless m = n, in which case it is the set of all nxn invertible matrices.

# If the noun is animate, natural gender tends to dictate grammatical gender.

If the player ascends the first eight strings of the bass bridge, they will encounter a flatted seventh ( C natural in this case ), because this note is drawn from the G tetrachord.

If the ham has less than 20. 5 % but is at least 18. 5 % protein, it can be called " ham with natural juices ".

Since counter-clockwise may be defined in terms of up, forward, and right, this experiment unambiguously differentiates left from right using only natural elements: If they were reversed, or the atoms spun clockwise, the radiation would follow the spin axis instead of being opposite to it.

# If a and p are natural numbers such that a < sup > p </ sup > − 1 is prime, then a

If that ideal size is large enough to supply the whole market, then that market is a natural monopoly.

If ( V, ‖·‖) is a normed vector space, the norm ‖·‖ induces a metric ( a notion of distance ) and therefore a topology on V. This metric is defined in the natural way: the distance between two vectors u and v is given by ‖ u − v ‖.

Today, biologists denounce the Naturalistic Fallacy because they want to describe the natural world honestly, without people deriving morals about how we ought to behave — as in: If birds and beasts engage in adultery, infanticide, cannibalism, it must be OK ).

If the key signature indicates G-sharp, a local flat before a G makes it G-flat ( not G natural ), though often this type of rare accidental is expressed as a natural, followed by a flat () to make this clear.

If the trend continues, more than half the forest that existed when Papua New Guinea became independent from Australia in 1975 will be gone by 2021.

If ecologically intact, the boreal forest has an estimated value of US $ 3. 7 trillion.

If the graph is not connected, then it finds a minimum spanning forest ( a minimum spanning tree for each connected component ).

* If we ignore isolated vertices, which will each be their own component of the minimum spanning forest, V ≤ E + 1, so log V is O ( log E ).

If the forest is replaced with only one species of tree and all other vegetation is prevented from growing back, a monoculture forest similar to agricultural crops would be the result.

* ( If you type a word that describes an object you see in the forest :) The trees of the forest are large hardwood oak and maple, with an occasional grove of pine or spruce.

* If a tree falls in a forest

If this ratio is adopted, 1, 240, 000 ha land is required to sustain the present population ; however, the total land available, excluding the reserve forest, is 928, 000 ha.

* If a tree falls in a forest

# If in swamp, desert, or forest, and X < 16, a random encounter occurs.

If, for instance, we take an agricultural field, and consider the mineralogic composition and the structure of its soil, we will find that whereas the first is quite similar to that of an undisturbed forest soil, the structure is quite different.

If anyone who fitted into one of the above categories was found in a forest, chase, down or Royal Park, they could be sentenced to death.

If is an undirected graph, and is the family of sets of edges that form forests in, then is clearly closed under subsets ( removing edges from a forest leaves another forest ).

Lucier notes a synchronistic event, his reading of If on a winter's night a traveler by Calvino: " What I would like most in the world ... is to make clocks run backward ... No, with thought, by concentrating until I force time to move back .... polydyptic theatre, in which about sixty little mirrors lining the inside of a large box transform a bough into a forest, a lead soldier into an army, a booklet into a library.

If the visitor is unlucky, he will join the many skeletons on the outskirts of the forest, with arrows piercing from both his eye sockets.
