Black-hole phenomenon

Similar studies have used intravascular ultrasound (IVUS) at six-month follow-up to evaluate differences in target-lesion healing and have found less intimal hyperplasia and late lumen loss due to increased plaque burden in patients who had received DES without ICB for the treatment of BMS ISR (41). On the other hand, other IVUS-guided studies have described a significant black-hole phenomenon in patients who have undergone ICB. The black hole, a homogeneous, echolucent intraluminal entity depicted on IVUS, is felt to be a result of an impaired response to endothelial injury and an altered molecular proliferative response (Fig. 2). This intraluminal tissue, which accounted for —50% of the neo-intimal growth in areas of restenosis after radioactive stent...

Dark matter may be driven near the black hole gravitationally, and may form a dense concentration around it Gondolo Silk (1999). We will call this concentration a spike, so as to distinguish it from the dark matter cusps of Section 3.2.2. The formation of a spike is gravitational phenomenon similar to but less efficient than accretion of matter, in that the latter involves dissipation of energy and angular momentum and can thus produce concentrations which are smaller and denser. 

Below we focus on the observed association of GRBs with an energetic subclass of core-collapse supernovae, type Ibc SNe, which with each new finding provides an increasing evidence that the GRB phenomenon is related to the evolution of most massive stars and formation of relativistic compact objects (neutron stars and black holes). 

Tunneling is a ubiquitous phenomenon. It is observed in biological systems (1), and in electrochemical cells (2). Alpha particle disintegration (3), the Stark effect (4), superconductivity in thin films (5), field-electron emission (6), and field-ionization (7) are tunneling phenomena. Even the disappearance of a black hole (or the fate of a multi-dimensional universe) may depend on tunneling, but on a cosmological scale (S-9). 

The author himself regards SSCM in its present form as natural philosophy rather than proven science, but its potential to elucidate cosmic phenomena is enormous. Cosmological redshift is a relevant example. As observed it is a galactic-scale phenomenon, which should correlate with an atomic-scale counterpart. The proposed chemical redshift (5.1.2) is the most likely candidate for this role. The theory predicts an enormous number of small black holes, which, re-interpreted as penetrating a vacuum interface, may lead to the recognition of new sources of astronomical luminosity. 

Lense-Thirring effect An effect predicted to occur in general relativity theory by J. Lense and Hans Thirring in 1918 in which a compact rotating body causes the space near it to rotate in the same direction. The phenomenon is also known as frame dr ng. It has been reported in observations of neutron stars and black holes. Measurements have also been made using shifts in the orbits of satellites around the earth. 

Active galactic nuclei When massive black holes accrete, their immediate environment, usually thought to consist of an accretion disk and a relativistic jet, emits a luminosity often far in excess of the emission of all stars in the host galaxy put together this phenomenon is called an active galactic nucleus. 

Consider first the phenomenon, which is called rejection of a filler by rubber. When a silica filler is charged onto premasticated natnral rubber, fine particles of the filler are blown out from the charge hole of the internal mixer like smoke. It is interpreted as a repulsion by the electric charge built in the rubber during mastication. When silica is premixed with carbon black or fine powdered metal carbonates, the repnlsion is significantly reduced [9].
