intruduction: red beds have been widely studied by palaeomagnetic methods for what they can tell us about the history of sedimentary basins and their subsequent deformation (collinson, 1974, turner, 1979a,b and 1981, mccabe and elmore, 1989, elmor, et al., 1993 and 2000). this study has investigated the palaeomagnetism of the cambrian red sediments (dezou and dahou formation) of the eastern mar...

We describe investigations of the largely unexplored field of mesoscopic type-I superconductors. Micromagnetometry and 3D Ginzburg-Landau simulations of our single crystal β-tin samples in this regime reveal size- and temperature-dependent supercritical fields whose behavior is radically different from the bulk critical field H(c)(B). We find that complete suppression of the intermediate state ...

The ground-state structure of the two-dimensional random field Ising magnet is studied using exact numerical calculations. First we show that the ferromagnetism, which exists for small system sizes, vanishes with a large excitation at a random field strength-dependent length scale. This breakup length scale L(b) scales exponentially with the squared random field, exp(A/delta(2)). By adding an e...

We analytically study scalarization of higher-dimensional charged Reissner-Nordstr\"{o}m (RN) black hole. It is shown that static massive scalar field which non-minimally coupled to Gauss-Bonnet invariant can be supported by hole in super-critical charge regime $Q/M\ge \bar{C}_d$ with $Q, M$ and mass the $\bar{C}_d$ some unitless spacetime dimension-dependent quantity. Moreover, we show shell q...

introduction: electrophysiological studies have demonstrated a relationship between aging and atrioventricular (av) nodal conduction and refractoriness. the aim of the present study was to determine the effects of nodal aging on dynamic av nodal field potential recording during atrial fibrillation (af) in rabbit. methods: two groups of male new zealand rabbits (neonatal 2-week-olds and adult 12...

This study aims to see the effect of 3 types cognitive styles on students' mathematical reasoning abilities. According previous research, there has been no research that discusses The method in this is a qualitative descriptive approach. total population was 32 people who sat SMA class X MIPA A. selection subjects viewed from top results based categories field dependent style, intermediate and ...
