Preliminary results show microradiography and scanning electron microscopy (SEM) to be more accurate methods of accessing growth layer groups (GLGs) in the teeth of Tursiops fmncarus than transmitted light microscopy. Microradiography shoas the rhythmic deposition of mineral as alternating radiopaque and radiolucent layers. I t improves the resolution of CLGs near the pulp cavity in older indiv...

in this work, the effects of acetic and lactic acids addition to rice during cooking, on the texture and morphological properties, and too, the gelatinization temperature (gt) of the cooked domsiyah rice was investigated. all experiments were carried out in triplicate and data analyzed in randomized completely by spss15 software. the results showed that acid addition to rice during cooking caus...

The dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. Cu and Ni Unites nanocatalyst powders sithcomposition of Caned], and NiFe204 were synthesized by a sol-gel auto catalnic combustion process. Themolar ratio between metal ions and urea was 11.2. The sob gel process was done at 8...

The scanning electron microscopy (SEM) is probably one the most fascinating examination approach that has been used since more than two decades to detailed inspection of micro scale objects. Most of the scanning electron microscopes could only produce 2D images that could not assist operational analysis of microscopic surface properties. Computer vision algorithms combined with very advanced ge...

A scanning electron microscopy (SEM) and transmission electron microscopy (TEM) study was made of lesions from acute, experimentally induced cases of jaagsiekte. In the SEM study tumour cells were easily identified by the abundant microvilli on their peripheral surface. The SEM study gave further insight into the development of lesions and the spatial relationship of cells involved in jaagsiekt...

Despite being an excellent tool for investigating ultrastructure, scanning electron microscopy (SEM) is less frequently used than transmission electron microscopy for microbes such as viruses or bacteria. Here we describe rapid methods that allow SEM imaging of fully hydrated, unfixed microbes without using conventional sample preparation methods. We demonstrate improved ultrastructural preserv...

there is no single standard technique or methodology to characterize the size, structure, number, and chemical composition of airborne carbon nanotubes.  existing analytical instruments and analytical techniques for evaluating nanoparticle concentrations cannot simultaneously provide morphology, state of agglomeration, surface area, mass, size distribution and chemical composition data critical...
