Investigation of CPD and HMDS Sample Preparation Techniques for Cervical Cells in Developing Computer-Aided Screening System Based on FE-SEM/EDX
This paper investigated the effects of critical-point drying (CPD) and hexamethyldisilazane (HMDS) sample preparation techniques for cervical cells on field emission scanning electron microscopy and energy dispersive X-ray (FE-SEM/EDX). We investigated the visualization of cervical cell image and elemental distribution on the cervical cell for two techniques of sample preparation. Using FE-SEM/...
متن کاملEXPLORING THE TACTILE MODALITY FOR HMDs
Humans commonly are considered to have five separable named senses, called hearing, sight (vision), smell, taste, and touch, providing information about the external world. These senses, their organs, and respective modalities are listed in Table 18-1. The two most dominant senses are sight and hearing. Equipment designers understand human reliance on these two senses and have used them as the ...
متن کاملHybrid SEM/AFM System from Carl Zeiss Revolutionizes Analysis of Functional Micro-and Nanostructured Specimen
The Scanning Electron Microscope (SEM) and the Atomic Force Microscope (AFM) are established methods for highest resolution imaging. While the SEM provides a continuous zoom range from millimeter to micrometer dimensions with a very large depth of focus, the AFM provides absolute measurements of all three dimensions down to atomic level, but can only, due to its working principle, measure in th...
متن کاملSpecimen holders for simultaneous critical point drying of multiple biological specimens.
Specimen holders were developed for simultaneous critical point drying of multiple specimens of monolayer cell cultures grown on Leighton tube glass cover slips or for specimens of cells collected on silver or cellulose membrane filters. The use of these multiple specimen holders makes it possible to process several specimens in parallel and thus significantly reduce the time required for handl...
متن کاملMimicking Human Vision in Hmds
Head mounted displays (HMDs) have disappointed real world users in their inability to live up to over-hyped expectations. This does not, however, mean that HMDs are useless. While still technologically lacking in some areas, appropriately designed HMDs can be extremely useful tools. We will look at the limitations of current HMDs and ways around them. Rather than approach the problem from the o...
