Riemann curvature-stretching coupling in dynamo torus laboratory and in UHF twisted plasma loops
Kleeorin, Rogachevskii, Tomin and Sokoloff [Phys Rev E79,046302,(2009)] have shown that Roberts slow dynamo can be transformed into a fast dynamo by allowing its coefficients randomly fluctuate. Stretching, fundamental for fast dynamo action, is increased by mean helicity flow. Previous investigation on slow dynamo plasma and anti-fast dynamo theorem in Riemannian geometry [Garcia de Andrade, P...
متن کاملInvestigation of the prevalence of Torus Mandibularis and Torus palatinus in Attendants of rafsanjan Dental school
the prevalence of Torus palatinus and Torus Mandibularis is widely different in various populations and races.this descriptive study was performed in 1999,to investigate the the prevalence of Torus Mandibularis and Torus palatinus in patients referring to Rafsanjan dental school.584 patients(268 men and 316 women) which were over 18 years old were examined.the information recorded in the questi...
متن کاملTorus Bundles over a Torus
1. If a compact Lie group P acts on a completely regular topological space E then E is said to be a principal P-bundle if whenever the relation px — x holds for pÇzP, x£E it follows that p = e, the identity of P. The orbit space X = E/P is called the base space and the map tt: E—>X carrying y into its orbit P-y is called the projection. Suppose now that G is a Lie group, 77i a closed subgroup o...
متن کاملDynamo Mechanisms
Dynamo theory is reviewed with particular emphasis on recent developments. There now seems to be a strong case for dynamo eeects that are driven by the magnetic eld itself. This is linked to recent interpretations of the observed stellar cycle periods which suggest that the ratio of cycle frequency to rotational frequency increases, up to some point, with stellar chromospheric activity. This ra...
