The primary intent of the present paper is to adapt familiar notions of algebraic topology, such as the fundamental group, homology, and cohomology to the context of algebraic maps and their (ramified) covering projections. The notion of a principal derived map is already fairly well understood in terms of the defining voltages; however, once it is… (More)
The regular coverings of regular affine algebraic maps are considered, and a large family of totally ramified coverings—the so-called Steinberg and Accola coverings—are fully classified.
This systematic review aims first to summarize the previous areas of application of computational fluid dynamics (CFD) and then to demonstrate that CFD is also a suitable instrument for generating three-dimensional images that depict drug effects on nasal mucosa. Special emphasis is placed on the three-dimensional visualization of the antiobstructive effect… (More)
Blood analysis proved no significant findings, though cases of neutrophilia and leukopenia were detected. Conclusions: Limited resources, restricted participation from all the possible H1N1VI patients, thus biasing results due to small sample size; however, the obtained data is consistent with existing reports, nevertheless the information is not enough to… (More)
