Conclusions,se new materials have T. values (critical temperature — the onset of superconductivity) which are above the boiling point of liquid nitrogen. This fact has made their potential use very attractive due to the relative cheapness of liquid nitrogen compared to other coolants and refrigeration technique

To study the LU connections we must apply the theory of graphs, as suggested by Forman and Godron. Fractal analysi

Because in many cases the physiologically determined limits of species ranges occur within ecotones (Curtis 1959, Chabot and Mooney 1985), these transition zones may be se

Thus, differences are identified in the contexts by which these two termsappear in the literature. While underscoring the central role of geography in this analysis, i
