Zero-degree focusing of channeled ions and crystal rainbows
(Physics Letters A, 2001)
We analyze here theoretically the connection between the effect of zero-degree focusing of channeled ions and the crystal rainbow effect. The calculations were performed for Ne10+ ions and a LT 100 GT Si thin crystal. The ...
Central and baroreflex control of heart rate during the wake-sleep cycle in rat
(Sleep, 2001)
Spontaneous fluctuations in Heart Period (HP) and Mean Arterial Pressure (MAP) make it possible to evaluate baroreceptor-heart rate reflex sensitivity (BRS). 30-s sequences of HP and MAP beat-to-beat values were considered ...
Simple Fluorescent Micronucleus Assay-combination of Hg-banding Technique and In situ Hybridisation
(Sciences, 2001)
Recent development in cytogenetic and molecular techniques, particularly combination of cytochalasin B method and fluorescence In situ hybridisation (FISH) now allow sensitive identification of clastogenic versus aneugenic ...
Determination of parameters for channeling of protons in SiC polytype crystals in the backscattering geometry
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2001)
Energy spectra of protons channeling along the (0001) axis of several SiC polytype crystals (namely 4H, 6H, 15R, 21R) in the energy region E-p = 1.7-2.5 MeV, in the backscattering geometry, were taken and analyzed. Computer ...
Uranium contents from bomb craters
(Journal of Environmental Protection and Ecology, 2001)
Depleted uranium (DU) is a by-product of uranium enrichment process and its use is very dangerous and harmful. We measured uranium concentration in the surface soil (0-5 cm depth) from bomb craters caused by cruise missiles ...
Monte Carlo Simulation of Proton Transport at Therapeutic Energies
(Nuklearna tehnologija, 2001)
Physical and biological characteristics of protons as well as technical requirements on proton beams are reviewed in order to illustrate the need for accurate proton transport simulations for therapeutic applications. ...
