An ultraviolet absorption, as well as Stokes and anti-Stokes Raman resonance scattering of spectroscopically pure SiO2 was investigated by flash photolysis technique. The whole spectrum of 'absorption and scattered bands' was recorded photographically in ultraviolet. A resonance absorption line was observed at 288.2 nm, without structure, while scattered(More)
In principle the optical energy absorbed by a complex molecule raises that molecule to one of its excited states, and afterwards this excitation energy decays through the different relaxation channels. Initially, electronically excited naphthalene emits photons in the phosphorescence band of naphthalene and these emitted photons are absorbed by the acceptor(More)
Garnets doped with Nd+3 have attracted extensive interests because of their applications in solid-state lasers, as well as upconversion luminescence and magneto-optical and magnetic properties. Usually, these properties are closely related to the local structures and properties of the Nd+3 impurities in the hosts. Since information about electronic states(More)

BACKGROUND/AIMS One of the most important complications of acute pancreatitis is the secondary bacterial infections of the pancreas and gut. Translocation of bacteria from the gut is accepted as being responsible for the development of septic complications in acute pancreatitis. In this study, our aim was to investigate the effect of PARP inhibition via(More)
