Abstract Nowadays, virtual laboratories are widely used in education and training universities. Such labs do gain some effect teaching, assisting students to be familiar with the experimental steps. However, these systems tend relatively simple. There is room for improvement helping understand principles. This particularly evident teaching of atomic force microscopy. In order overcome shortcomi...

this paper is devoted to compiling a site geology map for town of amiriyeh, from seismic macro-zonation point of view using geophysical methods of shallow seismic, down-hole seismic and resistivity surveys. in this map site geology has been classified based on shear wave velocity, according to the criteria for site geology classification offered in the iranian code of practice for seismic resis...

We describe a patient who developed topographical memory loss after a closed head injury. His symptoms and the psychological test results indicate a selective deficit of topographical memory, his perceptual and spatial skills being relatively unimpaired.

Using the recently developed SIMS-SPM prototype, secondary ion mass spectrometry (SIMS) data was combined with topographical data from the scanning probe microscopy (SPM) module for five test structures in order to obtain accurate chemical 3D maps: a polystyrene/polyvinylpyrrolidone (PS/PVP) polymer blend, a nickel-based super-alloy, a titanium carbonitride-based cermet, a reticle test structur...
