Abstract:
A manuten o de níveis ótimos de potência muscular e a recupera o rápida s o imprescindíveis para o bomdesempenho no atletismo. O objetivo do estudo foi de comparar entre os gêneros a média dos escores deVO2máx e do RAST e correlacionar os níveis de VO2 máx e o índice de fadiga com os níveis de potênciamáxima e média. A amostra foi constituída de n=24 atletas com 16.3±2.51 anos, sendo n=12 do GêneroMasculino (GM) e n=12 do Gênero Feminino (GF). Considerou os níveis significativos p<0,05. Foramobtidos os seguintes resultados no RAST; Potência Máxima (GM) e (GF) 434.6±122.7 Watts e 293.8±66.2Watts (p=0.03); Potência Média 367±101.9 Watts; 226.6±53.0 Watts (p=0.02) e na Potência Mínima302.5±80.2 Watts e 237.2±206.6 Watts (p=0.00). Nos valores relativos, (GM) e (GF) a Potência Máxima foide 7.05±1.70 Watts/Kg e 5.49±1.22 Watts/Kg (p=0.02); Potência Média 5.95±1.36 Watts/Kg e 4.22±0.99Watts/Kg (p=0,01); Potência Mínima 4.89±1.07 Watts/Kg e 3.06±1.27 Watts/Kg (p=0,01). No VO2máx o(GM) (GF) obtiveram 41.1±6.2 ml.(kg.min)-1 e 32.6±6.4 ml.(kg.min)-1 (p=0.00). Encontrou uma correla ono VO2máx e Potência Máxima (r= 0.6744 / p= 0.01), VO2máx e a Potência Média (r= 0.8227 / p= 0.00),Potência Máxima e o índice de Fadiga (r= 0.7326 / p= 0.00). Conclui-se que as diferen as significativasencontradas nos valores de potências máxima, média e mínima (Watts) (Watts/Kg), ratificam estudosanteriores. A correla o do VO2máx e a potência média, apontam para uma possível rela o direta, fato que,se confirmado, pode ajudar a entender resultados de atletas de vários níveis.

Abstract:
The present paper interprets matter as a chain system of quantum harmonic oscillators. A fractal spectral model of resonant oscillations in chain systems of protons generates a scaling mass spectrum, that reproduces the mass distribution of the celestial bodies in the Solar System.

Abstract:
Logarithmic scaling invariance is a wide distributed natural phenomenon and was proved in the distributions of physical properties of various processes — in high energy physics, chemistry, seismicity, biology, geology and technology. Based on the Gantmacher-Krein continued fraction method the present paper introduces fractal scaling models of resonant oscillations in chain systems of harmonic oscillators. These models generate logarithmic scaling spectra. The introduced models are not based on any statements about the nature of the link or interaction between the elements of the oscillating system. Therefore the model statements are quite generally, what opens a wide eld of possible applications.

The paper presents a fractal scaling model of a chain system of quantum harmonic oscillators, that reproduces some systematic features in the mass distribution of hadrons, leptons and gauge bosons.

Abstract:
Based on a fractal scaling model of matter, that reproduces systematic features in the distribution of elementary particle rest masses, the paper presents natural oscillations in chain systems of harmonic quantum oscillators as mechanism of particle mass generation.

Abstract:
Many guidelines and several standards exist for the development of good user manuals. But even though technical writers comply with all guidelines, problems will typically arise when users apply the manual in practice. Therefore, it is useful to have real users test the manual before it is published. This article discusses user tests in the form of think-aloud tests, with examples from the research project ”User Manuals for older adults”.

Abstract:
A generalization of implicit conservative numerics to multiple dimensions requires advanced concepts of tensor analysis and differential geometry and hence a more thorough dedication to mathematical fundamentals than maybe expected at first glance. Hence we begin to discuss fundamental mathematics and physics of RHD with special focus on differential geometric consistency and study numerical methods for nonlinear conservation laws to gain a solid definition of the term conservative. The efforts in tensor analysis will be needed when applying Vinokurs theorem to gain the strong conservation form for conservation laws in general curvilinear coordinates. Moreover, it will be required to slightly reformulate the artificial viscosity for such nonlinear coordinates. Astronomical objects are characterized by fast flows and high propagation speeds on the one hand but astronomical length and time scales on the other hand. Implicit numerical schemes are not affected by the Courant Friedrichs Levy condition which limits explicit schemes to rather impracticably small time steps. Implicit methods however produce algebraic problems that require matrix inversion which is computationally expensive. In order to achieve viable resolution, adaptive grid techniques have been developed. It is desired to treat processes on small length scales like shocks and ionization fronts as well as physics at the extent of the objects dimension itself like large scale convection flows and pulsations. The combination of implicit schemes and adaptive grids allows to resolve astrophysics appropriately at various scales. In the last chapter of this paper we study problem oriented adaptive grid generation in 2D and 3D. We establish three main postulations for an ideal grid and analyze several feasible approaches.
