I discuss the relation between arbitrarily high-order theories of gravity and scalartensor gravity at the level of the field equations and the action. I show that (2n+4)-order gravity is dynamically equivalent to Brans-Dicke gravity with an interaction potential for the Brans-Dicke field and n further scalar fields. This scalar-tensor action is then conformally equivalent to the Einstein-Hilber...

The value of the Jordan-Brans-Dicke coupling parameter ! is at present much more tightly bounded below by radar time delay experiments than it is by the predicted time variation of Newton's constant G. We point out the possibility of having a Jordan-Brans-Dicke-type scalar (i.e. a scale-free massless scalar eld or \dilaton") couple with diierent strengths to visible and to conjectured \dark" ma...

Cereal brans are good source of ferulic acid. An approximate global production of 150 million tons of cereal brans have been reported in 2004. These by-products are extensively used as animal feed, but active research is being carried out in this field to produce higher value added products from these. Many literature review assesses the various biotransformations of ferulic acid and the role o...

In this paper we study cosmological application of holographic dark energy density in the Brans-Dicke framwork. We employ the holographic model of dark energy to obtain the equation of state for the holographic energy density in non-flat (closed) universe enclosed by the event horizon measured from the sphere of horizon named L. Our calculation show, taking Ω Λ = 0.73 for the present time, the ...

Black holes in several dimensions and in several theories are studied and discussed. The theories are, general relativity, Kaluza-Klein, Brans-Dicke, Lovelock gravity and string theory.

A model of Einstein-Hilbert action subject to scale transformation is studied and then its correspondence with modified gravity and Brans-Dicke theory is examined. PACS: 04.50.Kd
