Birds arose from their dinosaur ancestors and took to the skies over 100 million years ago. Since that time, birds have become abundant at high elevation, they have acquired the ability to migrate over the world’s highest mountains, and they have even found reason to soar over 11,000 m above sea level (18). These anecdotal observations alone may convince some of an avian supremacy at elevation....
در این پایان نامه مباحثی در مورد نیم گروه های معکوس توپولوژیکی اولیه (مطلقا) h-بسته و فشرده (شمارایی) بدست می آوریم و ساختار نیم گروه های معکوس توپولوژی فشرده شمارایی و نیم گروه های معکوس توپولوژی همنهشت-آزاد را توصیف می کنیم و نشان می دهیم که نیم گروه دو دوری نمی تواند در نیم گروه معکوس توپولوژی فشرده شمارایی نشانده شود. we present some discussions about compact (countably) and (absolutely) h...

More specifically, reversals in capital flows to emergin...

abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
