We studied the room temperature photoacoustic spectra of GaSe single crystals in the vicinity of the energy gap. Exciton formation was observed in both amplitude and phase spectra. The thermal source that arises in the ...

This paper compares some optical properties of different spiral inflectors using the program CASINO. The electric field distribution in the inflectors has been numerically calculated from an electric potential map produced ...

The effect of tropopause height on the content of Cs-137 and total beta activity in surface atmosphere was considered for the period of intensive nuclear weapon tests, from 1968-1971. The activity of Cs-137 in monthly air ...

In this letter we present a method for calculation of linear heat flow in inhomogeneous solids. The method is based on the evaluation of transfer matrices for each layer in a multilayered structure from the Laplace ...

The influence of the anharmonic vibron-phonon coupling, arising on account of a dressing effect, on the characteristics of the lattice subsystem in quasi-one-dimensional molecular crystals was examined within the pseudo-harmonic ...

A new method for the preparation of 25 Angstrom AgBr quantum dots has been developed. The room-temperature emission of size-restricted AgBr crystallites was observed. The emission spectrum of 25 Angstrom AgBr quantum dots ...

A numerical simulation procedure for the calculation of surface temperature in thermally inhomogeneous solids induced by a harmonically modulated external heat source is presented. The procedure is based on the separation ...

Polymerase chain reaction (PCR) is a very potent method enabling the amplification of target DNA sequences at least 10(5)-10(6) fold. The efficacy of PCR is measured by its specificity, efficiency (yield quantity) and ...

Polycrystalline samples of cadmium-manganese mixed oxides Cd1-xMnxO were synthesized by ceramic technology in a wide range of concentrations x (0.05 less than or equal to x less than or equal to 0.90). Their crystalline ...
