Tundra, a major zone of treeless level or rolling ground found in cold regions, mostly north of the Arctic Circle (Arctic tundra) or above the timberline on high mountains (alpine tundra).
The cause of volcanism across the Arabian Shield is still very much under discussion (Moufti et al. 2013; Rolandone et al. 2013), and although there are other volcanic fields, and a major zone of crustal rifting (the Red Sea rift) proximal to Harrat Rahat, little is known about their respective influences on magma generation within the harrat.
NSCs in the SVZ are thought to give rise to most central nervous system neurons and glia in the developing mouse telencephalon and continue lifelong to provide neural progenitors that migrate along the rostral migratory stream to the olfactory bulb, a major zone of adult neurogenesis [ 100].
Province I (the youngest crust, Nd model ages (TDM) = 0.8 0.2 Ga) is a remarkable region of Phanerozoic crustal growth, which may reflect a major zone for closures of the Paleo-Asian Ocean.
After the end of the Cold War, Turkey was seen as a prickly power in a tough neighborhood, one that included two major zones of instability, the Balkans and the Middle East.
The other major zones of lakes lie marginal to the Alpine system, while Scotland has its many "lochs" and Ireland its "loughs".
About 17,000 death sentences were handed down by the military commissions and revolutionary tribunals of the Terror, 72 percent for charges of armed rebellion in the two major zones of civil war the federalist southeast and the western Vendée region.
That was the revelation of the festival's first "Tap Internationals" evening, in 2001, and although the dozen or so participants in this year's showcase are less far-flung, three major zones of tap activity — Brazil, Japan, and Australia — are represented by excellent dancers.
Three major zones of habitat are usually present: (1) littoral, the shallow-water zone, with light penetrating to the bottom and supporting rooted plants and bottom-dwelling animals; (2) limnetic, the water open to effective light penetration, supporting plant and animal plankton; and (3) profundal, the bottom and deepwater area beyond light penetration, supporting dark-adapted organisms.
These household cookstove models are organized around the three major zones of the cookstove system: the fuel bed, the gas phase reaction zone, and the heat transfer zone.
This may represent evidence that the three major zones of the PFR and their distinct morphologies are heavily reliant for their formation on only a relatively few structural proteins, perhaps PFR1 and PFR2 (the only proteins that have been shown to localise to the PFR whose ablation results in a failure of PFR assembly).
