In this paper, we discuss how in certain theories of spacetime admitting a maximal proper acceleration Hawking radiation does not completely evaporate the black hole. The hole remnant’s mass depends on inverse acceleration. Furthermore, as consequence duality between minimum that Schwarzschild can have such spacetimes and acceleration, show with there must be an upper uniform bound value force ...

Neutron stars can be destroyed by black holes at their center accreting material and eventually swallowing the entire star. Here we note that accretion model adopted in literature, based on Bondi or variations thereof, is inadequate for small holes---black whose Schwarzschild radius comparable to, smaller than, neutron's de Broglie wavelength. In this case, quantum mechanical aspects of process...

Sample 1: insole from black boot 120 Sample 2: tissue lining leather of black boot 640 Sample 3: insole from red boot 11 Sample 4: tissue lining leather of red boot 1.3 or leather sofas and armchairs manufactured in China. This substance has a wide-spectrum biocide activity and it is contained in paper bags, and progressively it can evaporate and contaminate the leather, textiles, food, cosmeti...

This Application Note describes how the Agilent 380-ELSD Evaporative Light Scattering Detector was used to determine the effect of varying the evaporation temperature during the analysis of a mixture of herbicides with different volatilities. Phenylurea compounds are used extensively in agriculture as selective herbicides, however they are thermally unstable and degrade rapidly to isocyanates a...

A drop of solution containing nonvolatile solute is allowed to evaporate from a sphere-on-flat geometry. Left behind is a striking pattern of gradient concentric rings with unprecedented regularity. The center-to-center distance between adjacent rings, lambda(C-C), and the height of the ring, h(d), are strongly affected by the concentration of the solution and the properties of the solvent. The...

We study modifications of the Hawking emission in the evaporation of miniature black holes possibly produced in accelerators when their mass approaches the fundamental scale of gravity, set to 1TeV according to some extra dimension models. Back-reaction and quantum gravity corrections are modelled by employing modified relations between the black hole mass and temperature. We release the assump...

We interpret lattice data for the equation of state of pure gauge SU(3)c by an evaporation model. At low temperatures gluons are frozen inside the gluon condensate, whose dynamics is described in terms of a dilaton lagrangian. Above the critical temperature quasifree gluons evaporate from the condensate: a first order transition is obtained by minimizing the thermodynamical potential of the sys...

Three new volatile cobalt amidinate compounds were prepared: Co(tBuNC(R)NEt)2, R=Me, Et and n-Bu. They were characterized by elemental analysis, 1H NMR, X-ray structure analysis, melting point, vapor pressure, vaporization rate, thermal stability and chemical reactivity. They were found to evaporate cleanly without decomposition. Two of them are liquids at room temperature, allowing for more co...

After the gravity induced on the brane in the Randall-Sundrum (RS) infinite braneworld is briefly reviewed, we discuss the possibility that black holes evaporate as a result of classical evolution in this model based on the AdS/CFT correspondence. If this possibility is really the case, the existence of long-lived solar mass black holes will give the strongest constraint on the bulk curvature r...

We explore possible effects of vacuum energy on the evolution of black holes. If the universe contains a cosmological constant, and if black holes can absorb energy from the vacuum, then black hole evaporation could be greatly suppressed. For the magnitude of the cosmological constant suggested by current observations, black holes larger than ∼ 4× 10 g would accrete energy rather than evaporate...
