В статье рассматриваются мотивы повести выдающегося отечественного прозаика Юрия Красавина «Хуторок», которые можно трактовать как экзистенциальные: мотив одиночества, отчуждения, бессмысленности существования человека, заброшенного в бездну бытия. Произведение реалистично передаёт атмосферу эпохи, социально-нравственный кризис, переживаемый обществом период перестройки конца ХХ века. Мечты гер...

The features of applying the methods computer mathematics to numerical solution bi-characteristic system equations describing propagation radio waves in ionospheric plasma are considered. Based on comparison and exact solutions obtained for parabolic layer, accuracy was investigated.

we consider the semilinear elliptic boundary value problem  = ∈∂ω− δ = ∈ωu x xu x f u x x( ) 0;( ) λ ( ( ));where λ > 0 is a parameter, ω is a bounded region in rn with a smooth boundary, and f is asmooth function. we prove, under some additional conditions, the existence of a positive solution for λlarge. we prove that our solution u for λ large is such that = →∞∈ω|| u ||: sup| u(x) |xas λ ...

in this paper, one of the numerical solution method of one- particle, one dimensional timeindependentschrodinger equation are presented that allows one to obtain accurate bound state eigenvalues and functions for an arbitrary potential energy function v(x).for each case, we draw eigen functions versus the related reduced variable for the correspondingenergies. the paper ended with a comparison ...

Introduction: The purpose of this study was to compare the antibacterial effect of sodium hypochlorite gel and solution on Enterococcus faecalis (E. faecalis). The main purpose of a root canal treatment is to eliminate the bacteria and their products. Sodium hypochlorite solution has excellent antibacterial properties, but also some negative features. Materials and methods: Fifty six single...
