In the paradigm of effective field theory, one hierarchically obtains action Aeff[q,⋯] for some low(er) energy degrees freedom q, by integrating out high(er) ξ, in a path integral, based on an A[q,ξ,⋯]. We show how can integrate vector va A[Γ,v,⋯] and obtain Aeff[Γ,⋯] which, variation with respect to connection Γ, leads Einstein's equations metric compatible connection. The derivation predicts ...

The macroscopic and microscopic characters, physical constant values, extractive values, ash values and the behaviour of powder drug on treatment with different chemical regents, microchemical and histochemical analyses were conducted to characterize some pharmacognostical parameters of Curcuma amada linn. (Zingiberaceae).

In this note it is shown that near-extremal four dimensional dyonic black holes, where the dilaton is not constant, can be described by a microscopic model consisting of a one-dimensional gas of massless particles.

The cosmological constant is one of the most pressing problems in modern physics. In this Letter, we address the issue of its nature and computation using an analogue gravity standpoint as a toy model for an emergent gravity scenario. Even if it is well known that phonons in some condense matter systems propagate like a quantum field on a curved spacetime, only recently it has been shown that t...

Abstract We investigate a disordered version of a thermodynamic fiber bundle model proposed by Selinger, Wang, Gelbart, and Ben-Shaul a few years ago. For simple forms of disorder, the model is analytically tractable and displays some new features. At either constant stress or constant strain, there is a non monotonic increase of the fraction of broken fibers as a function of temperature. Moreo...

background and objectives: leptospirosis is considered to be the most widespread zoonotic disease in the world and can infect a wide range of animals. although the prevalence of clinical leptospirosis in cats is low, they are probably exposed to leptospires excreted by wild life, rodents etc. this study was performed to determine the serologic reaction of cats to leptospires and their importanc...

background: leptospirosis is a worldwide zoonosis causedby leptospira interrogans. leptospirosis results in decreasedmilk production, abortion, stillbirth, infertility and mortality,which causes financial loss in the cattle industry. objectives:the aim of this research was to perform a serological andbacteriological study of leptospirosis in 6 industrial dairy herdsand 3 feedlots with previous ...

A method for performing scanning tunneling potentiometry of semiconductor heterojunctions is described. The method yields a direct measure of the electrostatic potential distribution across the interface, with microscopic resolution. The measurement is accomplished by scanning the probe tip at constant sample-tip separation across the junction, and adjusting the sample-tip voltage to maintain a...

We derive the explicit three-body contact potential for a dilute condensed Bose gas from microscopic theory. The three-body coupling constant exhibits the general form predicted by Wu [Phys. Rev. 115, 1390 (1959)]] and is determined in terms of the amplitudes of two- and three-body collisions in vacuum. In the present form, the coupling constant becomes accessible to quantitative studies which ...

The most important applications of the quantum Hall effect (QHE) are in the field of metrology. The observed quantization of the resistance is primarily used for the reproduction of the SI unit ohm, but is also important for high precision measurements of both the fine structure constant and the Planck constant. Some current QHE research areas include the analysis of new electron-electron corre...
