Composite biomaterial consists of bovine serum albumin 25 wt. % and single-walled carbon nanotubes <0.3 wt. %. This material designed for laser welding of biological tissues. Nonlinear optical characteristics were studied for determination of influencing the threshold effects in this composite, which occur during interaction with powerful laser radiation. The quality of this biomaterial was determined...
In single photon emission computed tomography exists scantily explored distorting factor called as solid angle fraction. There is investigated the influence of geometrical attenuation on the reconstruction quality depending on the gabarit of object, the system rotation radius and the absorption coefficient. The iterative method is offered for solid angle fraction distortion correction of the reconstructed...
Analytical expressions of the electrokinetic potential for cylindrical and spheroidal particles were obtained. It was shown that the electrokinetic potential of cylindrical and spheroidal particles is determined by the function, which depends only on the aspect ratio. Dependencies of the electrokinetic potential for cylindrical and spheroidal particles on the aspect ratio were calculated.
