Currently, optical devices, such as microscopes and CCD cameras, are mainly utilized for identification of bullets and tool marks in the field of forensic science. While these optical methods are easily manageable and effective, they are under great influence of illumination condition. Besides these appearance-based approaches, we can utilize 3D geometric data of tool marks that are free from l...

formulation is given in terms of the coupling of the fluctuating axial fields (Ẽz ,B̃z) and incorporates shear and compressional Alfvén waves, drift waves, and ion acoustic waves. The kinetic response of the electrons includes pitch-angle scattering ~Lorentz model! and the ions are treated as a magnetized, cold fluid. Detailed quantitative comparisons of the theoretical predictions are made with...

Recent research and development in laser machining and laser forming processes is reviewed. In the laser machining area, striation formation and prediction, and gas jet workpiece interactions are discussed. In the laser forming area, strain rate effects, and convex forming are presented.

The expression of the intermediate filament (IF) constituents desmin, vimentin and keratin, as well as the striated-muscle-specific marker titin, was studied in mouse embryos of 8.0 to 9.5 days post coitum (d.p.c.), using the indirect immunofluorescence technique in combination with polyclonal and monoclonal antibodies. During the development of the embryo, desmin was first detected at 8.25 d.p...
