The dust ball collapse is studied in the context of "rainbow metric" approach (where matter content supplemented with a scalar field perturbation) to Oppenheimer-Snyder scenario within framework loop quantum cosmology. global spacetime structure determined for this and subsequently used evaluate entanglement entropy via slight adaptation existing formulas. resulting model shown qualitatively re...

The concept of alliance or preferably ‘alignment’, as I shall explain below – is central to the conduct of international politics, and thus the discipline of International Relations (IR). Duffield et al. (2008: 291) identify that ‘Alliances are one of the most significant phenomena in security studies and world politics more generally’, while Modelski (1963: 773) considers them ‘one of a dozen ...

Objective: Dysfunctional beliefs of tuberculosis patients have pivotal role in treatment and development of their serious psychiatric problems. Cognitive group psychotherapy has been utilized to manage the dysfunctional beliefs. Methods: In a quasi-experimental study and a pretest and posttest design, 24 male tubercular patients were selected by convenient sampling and then randomly assigned...

Most people are aware that regular alcohol drinkers can become tolerant to the effects of alcohol. Tolerance can lessen the outward manifestations of intoxication, and this poses challenges for the drinker and other observers, including law enforcement officers. On the basis of a National Institutes of Health-funded longitudinal study examining a cohort of convicted alcohol-impaired drivers, th...

Abstract We shall study the formation of a particular class regular black holes (BHs) from gravitational collapse massive star. The inside geometry is described by spatially flat Friedmann–Robertson–Walker (FRW) metric and stellar matter distributed uniformly without any pre-assumption about its equation state. Our model generalization Oppenheimer–Snyder for BHs. have obtained density pressure ...
