Polar pressures
The retreat of Arctic summer sea ice has been dramatic in recent years as recorded by satellite images. But it also appears that the thickness of ice has also experienced equally significant shrinkage. Most computer models predict ice-free summer conditions by 2040 to 2100 but real conditions appear to be moving faster than this. The British Catlin Arctic Survey, which got underway in February,...
متن کاملOn the polar derivative of a polynomial
For a polynomial p(z) of degree n, having all zeros in |z|< k, k< 1, Dewan et al [K. K. Dewan, N. Singh and A. Mir, Extension of some polynomial inequalities to the polar derivative, J. Math. Anal. Appl. 352 (2009) 807-815] obtained inequality between the polar derivative of p(z) and maximum modulus of p(z). In this paper we improve and extend the above inequality. Our result generalizes certai...
متن کاملClimate pressures
Climate change is rising up many agendas, from over-arching politics to detailed and focused research. The anthropogenic input of carbon dioxide and other greenhouse gases into the atmosphere is well documented and evidence is already building that the earth's climate is warming but the impact of this and future changes remain uncertain, particularly in higher latitudes where changes may be mor...
متن کاملPolarity inversion in polar-nonpolar-polar heterostructures.
We have observed an epilayer-thickness-dependent polarity inversion for the growth of CdTe on Sb(Bi)/CdTe(111)B. For films with Sb(Bi) thicknesses of less than 40 A (15 A), the CdTe layer shows a B (Te-terminated) face, but it switches to an A (Cd-terminated) face for thicker layers. On the other hand, a CdTe layer grown on Bi(Sb)/CdTe(111)A always shows the A face regardless of Sb or Bi layer ...
متن کاملm-polar intuitionistic graphs and its properties
In many real world problems, data sometimes comes from n agents (n≥2), multipolar information exists. For issues that are associated with uncertainty, this information can not be showed with the values of crisp, fuzzy, intuitionistic or bipolar. Graph is one of the mathematical models widely used in different sciences. Ambiguity in a graph where data depends on the n parameter can not be showed...
