The control of the magnetization inversion dynamics is one main challenges driving design new nanostructured magnetic materials for magnetoelectronic applications. Nanoparticles with onion-like architecture offer a unique opportunity to expand possibilities allowing combine different phases at nanoscale and also modulate coupling between by introducing spacers in same structure. Here we report ...

than those for 100 % curves. Since there exists no non-decreasing functional relationship between germination percentage and energy loss in this region, ionizations in the fruit coat cannot be responsible for the induced germination. Likewise, in the region of the embryo there is a 69 % germination curve which lies above a 100 % curve. (In both of these cases visible embryo damage could be seen...

The exact nature of η Carinae is still an open issue. Strict periodicity in the light curves at several wavelengths seem to point out to a binary system, but the observed radial velocities, measured from space with high spatial resolution are in conflict with the ground based observations used to calculate the binary orbit. Also, the observed 2-10 keV X-ray flux is much larger that what is expe...

we report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (mtu) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (au-nps). this thiol-containing molecule exhibits intriguing affinity with au-nps. the reactivity involves the displacement of the citrate shell by the thiolate shell followed ...

The ‘rise time’ of a gamma-ray burst, which may be defined as the radiation pulse width from a small segment of a fireball’s spherical shell wherein second order effects like shell curvature are unimportant, is conventionally attributed to photon time delay across the thickness of the shell. If the intervening space between the observer and the fireball is inhomogeneous at the minimum level giv...

the mesolimbic dopamine (da) system contains both d1-like and d2-like receptors, has been connected to control of locomotor behavior. an apparent role for d1 and d2 receptors throughout the mesolimbic system in the alteration of locomotor behavior has been demonstrated in pharmacological studies. the nucleus accumbens (nac) is comprised of a core and a shell subregion, which is a component of t...

SN 1993J is to date the radio supernova whose evolution has been monitored in greatest detail and the one which holds best promise for a comprehensive theoretical-observational analysis. The shell-like radio structure of SN 1993J has expanded in general accord with models of shock excited emission, showing almost circular symmetry for over 8 years, except for a bright feature at the south-easte...

A simplified kinetic model called Spring Pendulum is developed for a spherical rolling robot with soft shell in order to meet the needs of attitude stabilization and controlling for the robot. The elasticity and plasticity of soft shell is represented by some uniform springs connected to the bracket in this model. The expression of the kinetic model is deduced from Newtonian mechanics principle...
