Total Diffraction Reflection of Polarized Neutronsby Crystal Surface With Polarized Nucleus, Placedin Periodical Variable Magnetic FieldHoàng Văn Ngọc, Nguyễn Đình DũngIn this article the differential cross-section of totaldiffraction reflection of polarized neutrons by crystalsurface with polarized nucleus placed in periodicalvariable magnetic field are obtained and discussed.Người trình bày: Hoàng Văn Ngọc56. Combined studies of cell response to electricpulses: A simple approach.Nguyễn Thị Thùy Nhung, Lê Thanh Tùng, NguyễnĐức Giang, Ngô Văn Thanh, Nguyễn Ái ViệtUsing the analytical calculations for the interactionbetween trapezoidal pulses and biological membranes[Kotnik et al, Biophys J. 2006, 90(2), 480-491] and theapproximate theory for pore creation and pore current[DeBruin et al, Biophysical Journal, 77, 3, 1999, 1213-1224], in this work, we have studied the effects ofelectric pulses on the cell responses, including theelectroporation phenomenon. We investigated thedependance of membrane potentials of outer (plasma)and inner (organelle) membranes, the membraneThành phố Đồng Hới (03- 06/8/2009) Trang 57/ 102currents and pore densities on the electric pulses. Ourapproach can be applied to target the inner membrane,making the cell selectivity available or developed tomore complex structures (triple cell model, themitochondria, for example). Our results are in verygood agreement with previous numerical calculations.Người trình bày: Nguyễn Thị Thùy Nhung57. Calculation of the Optical Absorption Power inRectangular Quantum Wire by Using State-Independent Projection TechniqueHuỳnh Vĩnh Phúc, Lê Thị Thu Phương, TrầnCông PhongLinear and nonlinear optical absorption power inrectangular quantum are calculated by using stateindependentprojection technique. The analyticalexperessions for the optical absorption power inrectangular quantum wires are obtained. The numericalresult for the dependence of the optical absorption poweron its energy as systems temperature T and theparameters charactering the sample have been done.Người trình bày: Huỳnh Vĩnh Phúc58.
