tance less than 8ep from the point P, then X and P lie together in a connected sub-set of M every point of which is at a distance of less than e from the point P. The setM is said to be uniformly connected im kleinen if for every positive number e there exists a positive number 68 such that if P1 and P2 are two points of M at a distance apart less than 58 then they lie together in a connected s...

Resumo: Na década de 1940, os Estados Unidos da América ainda não haviam se posicionado (oficialmente) em face a uma possível intervenção bélica na Segunda Guerra Mundial, porém, as capas muitas histórias quadrinhos época, assim como seu conteúdo, já traziam personagens nacionalistas enfrentando forças do Eixo, manifestando um posicionamento diante ocorrência guerra.

the mean, as the red component of the double is the stronger of the two. In other words a nebular line of slightly greater wave-length than 4649.2A would meet the requirements. There is actually such a line at 4649.5A. Both this and the one at 4267A probably exist as bright bands in the spectra of the Wolf-Rayet stars.4 The following is a summary of the wave-length comparisons which have been m...

With the success of programming models such as Khronos’ OpenCL, heterogeneous computing is going mainstream. However, these models are low-level, even when considering them as systems programming models. For example, OpenCL is effectively an extended subset of C99, limited to the type unsafe procedural abstraction that C has provided for more than 30 years. Computer systems programming has for ...

Professor Lafayette Benedict Mendel passed away early in the morning of December 9, 1935. Through his death the world lost a distinguished scientist, the University a wise teacher and trusted servant, and his pupils a beloved counsellor and friend. The scope of his interests was broad and he achieved distinction in several spheres of scientific activity, but he will probably be best remembered ...
