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.
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.
There has been in effect a successive shifting of zones of vegetation southwards from the pole.
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.
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.
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.
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.
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.
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.
Parmenides of Elea (544-430 B.C.) distinguishes five of these zones, viz.
A torrid zone, between the tropics of summer and winter, which was uninhabitable on account of heat; two frigid zones, uninhabitable on account of cold, and two intermediate temperate zones.
13 shows his map of the world reduced from a MS. at Wolfenbiittel, to which is added a diagram of the zones from a MS. at Ghent, which illustrates Macrobius' commentary on Cicero's Somnium Scipionis.
Along the west frontier there appear broad and strongly marked zones of Cretaceous limestone, alternating with Jurassic and Triassic, joined by a strip of Palaeozoic formations running from the north-west corner of Bosnia.
There are three main zones of woodland.
This surface drifting water is cold and as it enters into intermediate zones it remains colder than the water in situ there and is therefore denser; it sinks below the surface and continues to flow along the bottom either back to the polar regions or towards the equator.
It has a world-wide distribution, but finds its chief development in the temperate and frigid zones, especially of the northern hemisphere, and as Alpine plants.
As in European Russia, so in Siberia, three principal zones - the arctic, the boreal and the middle - may be distinguished, and these may be subdivided into several sub-regions.
It has an area of some 1,048,000 acres, slightly greater than that of Somersetshire, and consists of three well-marked zones running N.
Botanically, Natal is divided into three zones: (1) the coast belt, extending from the sea inland to heights of 1500 ft., and in some cases to 1800 and 2000 ft.; (2) the midland region, which rises to 4000 ft.; (3) the upper regions.
In these zones the flora varies from sub-tropical to sub-alpine.
As a rule flowers common to all zones are on the coast smaller and with paler colours than they are in the midlands.
If Transylvania be excepted, three separate zones are roughly 'distinguishable: the " highland," comprising the counties in the vicinity of the Northern and Eastern Carpathians, where the winters are very severe and continue for half the year; the " intermediate " zone, embracing the country stretching northwards from the Drave and Mur, with the Little Hungarian Plain, and the region of the Upper Alfold, extending from Budapest to Nyiregyhaza and Sarospatak; and the " great lowland " zone, including the main portion of the Great Hungarian Plain, and the region of the lower Danube, where the heat during the summer months is almost tropical.
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.
If on the other hand the number of zones be odd, the effects conspire; and the illumination (proportional to the square of the amplitude) is four times as great as if there were no obstruction at all.
By the aid of photography it is easy to prepare a plate, transparent where the zones of odd order fall, and opaque where those of even order fall.
In such experiments the narrowness of the zones renders necessary a pretty close approximation to the geometrical conditions.
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.
Mass extinction, deforestation, dead zones in oceans, and on and on and on.
I liked this, too; but the division of the earth into zones and poles confused and teased my mind.
