What can the quantum liquid say on the brane black hole, the entropy of extremal black hole and the vacuum energy? Using quantum liquids one can simulate the behavior of the quantum vacuum in the presence of the event horizon. The condensed matter analogs demonstrate that in most cases the quantum vacuum resists to formation of the horizon, and even if the horizon is formed different types of t...

There appears to be three, perhaps related, ways of approaching the nature of vacuum energy. The first is to say that it is just the lowest energy state of a given, usually quantum, system. The second is to equate vacuum energy with the Casimir energy. The third is to note that an energy difference from a complete vacuum might have some long range effect, typically this energy difference is int...

due to a nearby vacuum cleaner or a passing tramear. You will find that these devices will not help you when you are confronted with disease far from the resources of a modern hospital. The only thing that matters is whether or not you have taken heed to the lesson first taught in the Eastern Mediterranean over two thousand years ago, repeated again by the old Cromwellian captain-"the trooper t...

Abstract Image analysis is used to study the effect of sintering atmosphere and sintering times on the pores morphology of Astaloy CrM. The pores morphology was described by means of some parameters, Circular Diameter (DC)- which shows the diameter of equivalent circle for comparing the pore size, FElongation and FShape- which have different geometrical meanings. The results have been interpret...

The aim of this work was to evaluate different methods for Sr-measurement and to develop and construct a measurement system which can be integrated inside a vertical I-Vmeasurement system and be used for the measurement of commercial sized PV-modules at AIT Austrian Institute of Technology GmbH. In addition the Sr-measurement system is supposed to perform a measurement according to the standard...

The nonlocal vacuum condensates or vacuum correlators describe the distribution of quarks and gluons in the nonperturbative QCD vacuum [1]. Physically, it means that vacuum quarks and gluons can flow through the vacuum with nonzero momentum. Nonlocal condensates play an important role in hadron physics. The nonlocal properties of the vacuum condensates are of principle importance in the study o...

Different levels of claw vacuum during machine milking may influence milking performance and teat condition. The claw vacuum acts on the teat and is responsible for removal and transport of milk but is also causing potential effects on the teat tissue. In the absence of milk flow, the claw vacuum is similar as the system vacuum. During milk flow, the claw vacuum drops to lower levels depending ...
