We consider the thermodynamics of minimally coupled massive scalar field in 3+1 dimensional Taub-NUT background. The brick wall model of 't Hooft is used. A quantization condition on the energy of the matter field, similar to the Dirac quantization condition, is required to find well behaved solution of the scalar field wave equation.When Scharzschild like coordinates are used it is found that ...

This paper examines the effects of multicycles desorption/adsorption on water isotherms a typical cement–bentonite mixture. These were evaluated over relative humidity (RH) range 90% and 0.3%. study shows that, after first adsorption–desorption cycle, subsequent cycle shifted isotherm curves upward, particularly at RH < 70%, with high degree hysteresis. In contrast, > slightly downward lo...

There is a large amount of backfilled earth on both sides the wall and top lower Daning Reservoir’s cutoff wall, which greatly disturbed by project, safety needs to be evaluated. Based deformation law stress condition rigid during construction, according connection characteristics plastic structure, analysis carried out using field measurement data, so as deduce underneath, evaluate wall. The r...

A rigorous solution is developed from first principles to guide the preliminary design of cutoff walls installed to contain the migration of contaminants from source zones. The full analytic solution is used to develop a criterion for determining the configuration and hydraulics of optimal wall designs. The solution is used to demonstrate the interaction between the properties of the wall, the ...

In recent years, non-water reaction polymer grouting is a new technology for anti-seepage and reinforcement that has been widely employed in projects. However, there little research on the consequence of defective cutoff walls affecting seepage safety earth dams. To analyze influence number, location, randomness defects wall characteristics dam, three-dimensional finite element model typical da...

Recently Herzog has shown that deconfinement of AdS/QCD can be realized, in the hard-wall model where the small radius region is removed in the asymptotically AdS space, via a first order Hawking-Page phase transition between the low temperature AdS space and the high temperature AdS black hole in Poincare coordinates. In this paper we first extend Herzog’s work to the hard wall AdS/QCD model i...
