Anxiety and Hyperlocomotion Induced by Chronic Unpredictable Mild Stress Can Be Moderated with Melatonin Treatment
(Folia Biologica, 2016)
Preclinical studies have shown that melatonin exercised antidepressant-like and anxiolytic-like effects in animal models of anxiety. The aim of the present study was to correlate the changes in behaviour induced by melatonin ...
Photoacoustic measurement of internal quantum efficiency and observation of the exciton effect in GaSe with photoacoustic phase spectra
(Applied Optics, 1997)
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 ...
Snr Radio Spectral Index Distribution and Its Correlation with Polarization. a Case Study: the Lupus Loop
(Revista Mexicana de Astronomia y Astrofisica, 2017)
We use radio-continuum all-sky surveys at 1420 and 408 MHz with the aim to investigate properties of the Galactic radio source Lupus Loop. The survey data at 1435 MHz, with the linear polarization of the southern sky, are ...
The effect of tropopause height on the content of radioactive debris in surface atmosphere
(Environment International, 1997)
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 ...
Conduction of heat in inhomogeneous solids
(Applied Physics Letters, 1998)
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 ...
Soliton-induced modification of the speed of sound in quasi-one-dimensional molecular crystals
(Journal of Physics: Condensed Matter, 1998)
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 ...
Room-temperature luminescence of AgBr quantum dots
(Chemical Physics Letters, 1999)
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 ...
Wake effect in interactions of fast ions with supported two-dimensional electron gas
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2010)
We study the interactions of fast charged particles with a two-dimensional electron gas supported by an insulating substrate, describing its high-frequency plasmon excitations by a two-fluid hydrodynamic model with the ...
Preparation of Bi2Se3 quantum dots by dissolution of crystalline powder in acetonitrile
(Journal of Materials Science Letters, 1998)
Study on electronic properties of alpha-, beta- and gamma-AlH3 - The theoretical approach
(Computational Materials Science, 2017)
AIH(3) polymorphs (alpha-, beta-, gamma-) are highly promising materials for hydrogen storage and hydride electronics applications. Given the recent developments in the synthesis and hydrogen desorption approaches, here ...
