Abstract The recent developments related to the black hole information paradox have brought us a confusing object: replica wormhole. We are trying better understand object from viewpoint of thermo-mixed double and spontaneous symmetry breaking. In this paper, we show that wormhole can be regarded as transition between different degenerate vacua, corresponding gravitational partition function sh...

The three major vacuum systems serving the two-mile accelerator, the optical alignment system light pipe, and the beam switchyard (BSY) transport vacuum chambers are located as shown in Fig. 23-1. The accelerator vacuum system must maintain a very high vacuum in the accelerator to prevent RF electrical breakdown and electron scatter. Thirtytwo subsystems evacuate the accelerator to a design pre...

vacuum drying of salicornia herbacea l. was performed at different drying temperatures (50, 60, 70, and 80c) to evaluate the drying characteristics and the effect of drying temperatures on the quality of salicornia. as the drying temperature increased, the drying time decreased significantly (p< 0.05). the drying rate decreased with decrease in moisture content and increase in drying time. on ...

industrial production of thermoset composite components involves the application of a vacuum bagging and autoclave pressure to minimize void percentage, usually to less than 5%. phenolic resin systems generate water as a reaction byproduct via condensation reactions during curing at elevated temperatures. in this paper, vacuum bagging and simple manufactured autoclave curing systems are used fo...

the polymeric and non-polymeric petrochemical wastes are environmentally unfavorable materials. we have to found a way to reuse these wastes in a safe manner. in styrene-butadiene rubber (sbr) production plant two major wastes are produced one is a fine rubber powder and the other is recycled n-methyl pyrrolidone (nmp). in high-density polyethylene (hdpe) production plant also a low molecular w...

High-efficiency particulate air (HEPA) filtered vacuum cleaners are recommended by the U.S. Department of Housing and Urban Development for cleaning lead-contaminated house dust. We performed a randomized field study to determine whether a conventional (non-HEPA) vacuum cleaner could achieve cleaning results comparable with those of a HEPA vacuum cleaner. We compared the lead loading reductions...

We discuss the main myths related to the vacuum energy and cosmological constant, such as: “unbearable lightness of space-time”; the dominating contribution of zero point energy of quantum fields to the vacuum energy; non-zero vacuum energy of the false vacuum; dependence of the vacuum energy on the overall shift of energy; the absolute value of energy only has significance for gravity; the vac...
