He might have stepped from the pages ofa Dostoyevsky novel. His personality too seems to have combined the Rational and Romantic e...

In the paper, we present the results of the researches regarding the influence of atmospheric pollution and biodegradation on the stone of Trei Ierarhi (Three Hierarchs) Monastery of Iasi. The correlation of microclimatic factors (precipitations, humidity, temperature, frequency and wind speed) with the physicalchemical measurements of environment pollution (powders, gases) has a special import...

In 2001, The International Association for the Evaluation of Educational Achievement (IEA) studied children’s reading literacy and the factors associated with its acquisition. The IEA’s Progress in International Reading Literacy Study (PIRLS) assessed the reading achievement of 9and 10-yearsolds and collected information about the experiences children had at home and school when learning to rea...

We study ideal two-dimensional ( 2D ) electron-hole system in a strong perpendicular magnetic field using the Keldysh-Kozlov-Kopaev method and generalized random phase approximation. The Bose-Einstein condensation of the correlated pairs takes place on a single particle state with an arbitrary wave vector k in a symmetric 2D model. We show that the ground state energy per one exciton and the ch...
