The nicotinic acetylcholine receptor (nAChR) and the Na,K-ATPase functionally interact in skeletal muscle (Krivoi, I. I., Drabkina, T. M., Kravtsova, V. V., Vasiliev, A. N., Eaton, M. J., Skatchkov, S. N., and Mandel, F. (2006) Pflugers Arch. 452, 756-765; Krivoi, I., Vasiliev, A., Kravtsova, V., Dobretsov, M., and Mandel, F. (2003) Ann. N.Y. Acad. Sci.(More)
I. INTRODUCTION Single-event effects (SEE) cause one of the major reliability concerns in semiconductor electronic components and systems [1], [2]. High-energy neutrons, produced by cosmic rays in the Earth's atmosphere, may cause significant or dominating fraction of the SEE rate, or of the soft error rate (SER), at aircraft altitudes, but also in(More)
Our previous finding that the muscle nicotinic acetylcholine receptor (nAChR) and the Na,K-ATPase interact as a regulatory complex to modulate Na,K-ATPase activity suggested that chronic, circulating nicotine may alter this interaction, with long-term changes in the membrane potential. To test this hypothesis, we chronically exposed rats to nicotine(More)
A new quasi-monoenergetic neutron beam facility has been constructed at The Svedberg Laboratory (TSL) in Uppsala, Sweden. Key features include a neutron energy range of 11-175 MeV, high fluxes, user flux control, flexible neutron field size and shape, and spacious and easily accessible user area. The first results of the beam characterisation measurements(More)
—An extended version of the Cascade-Exciton Model (CEM) of nuclear reactions is applied to analyze nucleon-induced fission cross sections for 209 Bi and 208 Pb nuclei in the 45–500 MeV energy range. The available data on linear momentum transfer are analyzed as well. The results are compared with analytical approximations resulting from a comparative(More)
In fast neutron cancer therapy, approximately 50% of the cell damage is caused by recoil protons from neutron-proton (np) scattering. In the intermediate energy region, there is a need for unambiguous np scattering data with good precision in both the shape of the angular distribution and the absolute normalisation. The normalisation techniques have been(More)
Double-differential cross sections for light-ion (p, d, t, 3 He and α) production in oxygen induced by 96 MeV neutrons are reported. Energy spectra are measured at eight laboratory angles from 20 • to 160 • in steps of 20 •. Procedures for data taking and data reduction are presented. Deduced energy-differential and production cross sections are reported.(More)
We report on the photonic band gap effect in the visible range in a three-dimensional dielectric lattice formed by closely packed silica spherical clusters and by interconnected cavities filled with various liquids. The spectral position and the spectral width of the optical " stop-band " depend on the lattice period and on the relative sphere/cavity(More)
In recent years, an increasing number of applications involving fast neutrons have been developed or are under consideration, e.g. radiation treatment of cancer, neutron dosimetry at commercial aircraft altitudes, soft-error effects in computer memories, accelerator-driven transmutation of nuclear waste and energy production and determination of the(More)
