Examination of Tool Marks in the Scanning Electron Microscopege size (over a few microns) can be seen under an optical microscope with an optimal magnification of 2000X, the marks of smaller dimensions (below one micrometer) can not be revealed. This is a situation where the application of the scanning electron microscope is called upon.

Forensic Examination of Bulb Filaments by the Sem impact has to be acquired. In this review an attempt has been made to collect the comprehensive but widely scattered literature relevant in these respects. Case stories are presented ob bulb cases solved with the SEM under reference to the above points of view.

Comparison of the Particle Size Distribution of Alpha Quartz Found in Respirable Dust Samples Collecrticle size measurements indicate three reference standards, minus 5-μm Min-U-Sil, minus 5-μm Supersil, and NBS 1878 would be preferred over the fourth, Silver Bond B for quantitative quartz determinations in coal mine dusts by x-ray diffraction and infrared spectrometry.

Liver Tissue Preparation Using a Modified Cryoultramicrotomy Kit the mitochondria of rat liver before and after exposure to toxins both singularly and in mixtures. To obtain reliable and reproducible data it is critical that each step in the technique be carried out correctly. Any deviation in any of the steps will leave the final results in doubt.

These studies were based upon Glue-lift collection of GSR for examination in the scanning electron microscope with energy dispersive X-ray analysis. By performing “muzzle blast block” and “trigger-b

Since sulfur is the major endogeneous, inorganic element of hair keratin and this element is a stable (i.e. unwashable) constituent of hair cuticles, the line scanning distribution of sulfur in segments of hair has the potential to serve as a reference for comparative assessment of the mod

The impression consists of persistent dents or scratches and parallel striations which appear altogether on a lifted, scraped metal at each shoe-end. The contour of this “metal-lift” is often marked by fractures and its wavy, banded shape reve

Psychodynamic Aspects: Self-Image,er, individual characteristics are much more significant because they are less likely to occur purely by chance in a given population. Since the SEM can readily demonstrate individual characteristics when they are present, it can be an extremely useful tool for the forensic odontologist.
