She'd traveled nonstop, sticking to narrow country roads and the forest to avoid both people and zones marked as having any sort of radiation fallout from the nuke strikes.
The flora of Argentina should be studied according to natural zones corresponding to the physical divisions of the country - the rich tropical and sub-tropical regions of the north, the treeless pampas of the centre, the desert steppes of the south, and the arid plateaus of the north-west.
The following table shows the area of the rainfall zones in square miles: - The tropic of Capricorn divides Australia into two parts.
Dividing the land into zones of average summer temperature, the following are the areas which would fall to each: - Judging from the figures just given, it must be conceded that a considerable area of the continent is not adapted for colonization by European races.
The cultivated area may be divided into five agrarian regions or zones, named after the variety of tree culture which flourishes in them.
Between these regions of tree culture lie zones of different her- __________ _______ baceous culture, cereals, vegetables 3.1904.1905.
The Hydromedusae form a widespread, dominant and highly differentiated group of animals, typically marine, and found in all seas and in all zones of marine life.
An ordinary cambium is scarcely ever found in the Monocotyledons, but in certain woody forms a secondary meristem is formed outside the primary bundles, and gives rise externally to a little secondary cortex, and internally to a secondary parenchyma in which are developed numerous zones of additional bundles, usually of concentric structure, with phloem surrounded by xylem.
Supplementary vascular bundles, anomalous cambial zones, &c. It is often enormously developed and forms a very important tissue in roots.
The rough surface of the bark of many trees is due to the successive phellogens not arising in regular concentric zones, but forming in arcs which join with the earlier-formed arcs, and thus causing the bark to come off in flakes or thick chunks.
There has been in effect a successive shifting of zones of vegetation southwards from the pole.
Aristotle, too, gave greater definiteness to the idea of zones conceived by Parmenides, who had pictured a torrid zone uninhabitable by reason of heat, two frigid zones uninhabitable by reason of cold, and two intermediate temperate zones fit for human occupation.
Latitude, climate zones, longitude, &c.; and (3) the Comparative part, which " considers the From translator's preface to the English version by Mr Dugdale (1733), entitled A Complete System of General Geography,1 revised by Dr Peter Shaw (London, 1756).
So it has come about that the only practicable history of geographical exploration starts from the Mediterranean centre, the first home of that civilization which has come to be known as European, though its field of activity has long since overspread the habitable land of both temperate zones, eastern Asia alone in part excepted.
The angle which the earth's axis makes with the plane in which the planet revolves round the sun determines the varying seasonal distribution of solar radiation over the surface and the mathematical zones of climate.
Murray, as the result of his study, g divided the earth's surface into three zones - the continental to Al d ay.
Many subdivisions and transitional zones have been suggested by different authors.
(3) The temperate forests of evergreen or deciduous trees, according to circumstances, which occupy those parts of both temperate zones where rainfall and sunlight are both abundant.
Russia, may be subdivided into two zones-an intermediate zone and that of the steppes proper.
Of this line it is customary to distinguish several zones, lying, generally, parallel to it, and, differentiated chiefly by climatic differences.
In Hungary and Russia a zone-tariff system is in operation, whereby the charge per mile decreases progressively with the length of the journey, the traveller paying according to the number of zones he has passed through and not simply according to the distance traversed.
Late Minoan art in its finest aspect is best illustrated by the animated ivory figures, wall paintings, and gesso duro reliefs at Cnossus, by the painted stucco designs at Hagia Triada, and the steatite vases found on the same site with zones in reliefs exhibiting life-like scenes of warriors, toreadors, gladiators, wrestlers and pugilists, and of a festal throng perhaps representing a kind of " harvest home."
A tall funnel-shaped vase of this class, of which a considerable part has been preserved, is divided into zones showing bull-hunting scenes, wrestlers and pugilists in gladiatorial costume, the whole executed in a most masterly manner.
In North Carolina five of the seven life-zones into which North America has been divided are represented, but more of its area belongs to the upper-austral than to any other zone.
Neottiineae, including 90 genera, also terrestrial, contains thirteen more or less widely distributed tropical or subtropical subtribes, some of which extend into temperate zones; one, Cephalanthereae, which includes our British genera Cephalanthera and Epipactis is chiefly north temperate.
Among these some forms, as among the trees, extend much be y ond the tropic and ascend into the temperate zones on the mountains, of which may be mentioned Begonia, Osbeckia, various Cyrtandraceae, Scitamineae, and a few epiphytical orchids.
In the astral theology of Babylonia and Assyria, Anu, Bel and Ea became the three zones of the ecliptic, the northern, middle and southern zone respectively.
M.), may be divided into four natural zones or sections: - (i.) the plains north of the Caucasus mountains, comprising the administrative division of Northern Caucasia; (ii.) the Caucasus range and the highlands of Daghestan; (iii.) the valleys of the Rion and the Kura, between the Caucasus range and the highlands of Armenia; and (iv.) the highlands of Armenia.
Although the species are fewer in number than in most other families of fishes, they are widely spread and extremely abundant, peopling by countless schools the oceans of the tropical and temperate zones, and approaching the coasts only accidentally, occasionally, or periodically.
Since the semitropical and sub-tropical zones are nearer the course of the Gulf Stream, and are swept by the trade winds, their temperatures are more uniform than those of the zones of southern climate; indeed, the extremes of heat (103° F.) and cold (13° F.) are felt in the region of southern climate.
The mean annual temperature of the state is 70.8° F., greater in the sub-tropical than in the other climate zones, and the Atlantic coast is in general warmer than the Gulf Coast.
The alternate Fresnel's zones are blocked out or otherwise modified; in this way the original compensation is upset and a revival of light occurs in unusual directions.
The object-glass of a telescope, the Fresnel's zones are reduced to parallel and equidistant straight strips, which at certain angles coincide with the ruling.
We imagine a wave-front divided o x Q into elementary rings or zones - often named after Huygens, but better after Fresnelby spheres described round P (the point at which the aggregate effect is to be estimated), the first sphere, touching the plane at 0, with a radius equal to PO, and the succeeding spheres with radii increasing at each step by IX.
All that it is necessary to assume is that the effects of the successive zones gradually diminish, whether from the increasing obliquity of the secondary ray or because (on account of the limitation of the region of integration) the zones become at last more and more incomplete.
The component vibrations at P due to the successive zones are thus nearly equal in amplitude and opposite in phase (the phase of each corresponding to that of the infinitesimal circle midway between the boundaries), and the series which we have to sum is one in which the terms are alternately opposite in sign and, while at first nearly constant in numerical magnitude, gradually diminish to zero.
If the point under consideration be so far away from the geometrical shadow that a large number of the earlier zones are complete, then the illumination, determined sensibly by the first zone, is the same as if there were no obstruction at all.
If, on the other hand, the point be well immersed in the geometrical shadow, the earlier zones are altogether missing, and, instead of a series of terms beginning with finite numerical magnitude and gradually diminishing to zero, we have now to deal with one of which the terms diminish to zero at both ends.
Intermediate cases in which a few zones only are formed belong especially to the province of diffraction.
If, as in the last paragraph, we imagine a system of zones to be drawn commencing from the inner circular boundary of the aperture, the question turns upon the manner in which the series terminates at the outer boundary.
If the aperture be such as to fit exactly an integral number of zones, the aggregate effect may be regarded as the half of those due to the first and last zones.
If the number of zones be even, the action of the first and last zones are antagonistic, and there is complete darkness at the point.
