To determine if the ordinary light microscope is a useful tool in the detection and identification of crystals in synovial fluid 63 fluids (13 with monosodium urate (MSU), 14 with calcium pyrophosphate dihydrate (CPPD), one with both types of crystal, and 35 without crystals) were examined blindly by two observers, first with an ordinary light microscope, then with a polarising light microscope...

the aim of conducting this research was to evaluate the viscosity change in the continuous casting of steel moldpowders by altering their chemical compositions, using hot stage microscope analysis. 4 low-fluorine samplescontaining such compositions as mno, fe2o3, li2o, tio2 and zno, as well as another fluorine-free samplecontaining a combination of fe2o3 and tio2, were prepared in this research...

Microscope Image Processing is an area of digital image processing in which most of image processing techniques are applied on the image captured by the microscope. Due to technical advances in microscope, it becomes easy to interface microscope to image processing system. Most of the fields like medicine, biological research, test tube baby, cancer research, drug testing, metallurgy, etc need ...

Instead of forming an entire image at one instant, a scanning optical microscope (SOM) scans a beam of light across specimen in a regular pattern, or raster, and forms its image point by point. A point of light is focused to a diffraction-limited spot on the sample by the objective lens. An image is built up point by point by a detector, either below the slide (if the microscope is exclusively ...

Over the last few years, string theory has changed profoundly. Most importantly , novel duality relations have emerged which involve gauge theories of brane excitations on one side and various closed string backgrounds on the other. In this lecture, we introduce the fundamental ingredients of modern string theory and explain how they are modeled through 2D (boundary) conformal field theory. Thi...
