The scope of this talk is to present some preliminary results on an effort, currently in progress, to generate an exact solution of Einstein’s equation, suitable for describing spacetime around a rotating compact object. Specifically, the form of the Ernst potential on the symmetry axis and its connection with the multipole moments is discussed thoroughly. The way to calculate the multipole mom...

SIR, We appreciate the comment of Prof. Ernst [1]. Mayhew and Ernst [2] summarized the results of a qualitative analysis of five controlled trials with acupuncture in fibromyalgia syndrome (FMS) as follows: ‘Their methodological quality was mixed and frequently low. Three RCTs suggested positive but mostly short-lived effects and two yielded negative results. There was no significant difference...

We present a simple technique for generating new solutions of Einstein’s equations using such function transformations that leave the field equations in the Ernst form. In this context we recover all the known covariant transformations of Ernst equations and we find the role of the analytic ones. Finally we obtain a new asymptotically flat solution starting from the Kerr solutions.

A hundred years is but an instant in evolutionary time; however during his life that spanned a century, Ernst Mayr (1904-2005) made outstanding contributions to our understanding of the pattern and process of evolution. An ornithologist and systematist by training, Mayr embraced Darwinism and championed the cause of evolutionary biology throughout his long and highly productive career. Though b...
