In a previous paper we formulated a set of necessary conditions for the spherically symmetric weakly charged dust to avoid Big Bang/Big Crunch, shell crossing and permanent central singularities. However, we did not discuss the properties of the energy density, some of which are surprising and seem not to have been known up to now. A singularity of infinite energy density does exist – it is a p...

Due to the accelerated expansion of universe, possibility formation singularities has changed from classical Big Bang and Crunch include a number new scenarios. In recent papers it been shown that such may appear in inflationary cosmological models with fractional power scalar field potential. this paper we enlarge analysis by use generalised expansions their Hubble order describe all possible ...

In this paper, we investigate the massless Reissner-Nordstrom de Sitter metric in context of minimal length scenarios. We prove not only confinement energy density charged particles, both fermions and bosons, but also their ability to tunnel through cosmological horizon. These particles might be interacting with Dirac sea case they will appear outside horizon dS/CFT holography. This result may ...

This paper argues that in view of the resource crunch confronting many developing countries and the fall in overseas development aid flows to them, new sources of development finance need to be found. We consider international taxes, fees and levies that could considerably augment aid flows to developing countries and some of which may have coincident beneficial effects. Estimates of the revenu...

The purpose of this study was to compare electromyographic (EMG) activity of the abdominal muscles between the crunch exercise and five other popular abdominal exercises. Surface EMG recordings of four muscles (upper rectus, lower rectus, external oblique, and internal oblique) of the anterior abdominal wall were collected and analyzed on 20 healthy, male volunteers. EMG activity was recorded d...
