Determining the Difference Between Active and Inactive Caries White Spot Lesions Using Sodium Iodide
… white spot lesions were collected for analysis. Photomicrography, radiography and Scanning Electron Microscopy (SEM) assessments were used to study these specimens. Consistent with our hypothesis, radiographic images revealed a high penetration of NaI solution through the enamel of the 1st molar, …

Spray characteristics of throttle body fuel injection
… system. Qualitative data were obtained using photomicrography, schlieren photography and videotape. Additionally, the laser based Phase/Doppler Particle Analyzer was used throughout the investigation to make spatially resolved quantitative measurements of droplet size and velocity and fuel …

MODERN MORPHOLOGICAL TECHNIQUES AND THE EVOLUTIONARY BIOLOGY AND TAXONOMY OF SEPSIDAE (DIPTERA)
… techniques such as microcomputered-tomography, photomicrography and scanning electron-microscopy. First, I document how de-novo appendages evolved from male sternites and that it evolved twice in sepsids. Second, I demonstrate that sexual selection highly increases morphological divergence by …

Phytoremediation of Sembrong River waters using neptunia oleracea and pistia stratiotes
… plants were not hyperaccumulators of Zn. Using photomicrography transverse sections of plant tissues cultivated in river water showed toxic symptoms like distortion, increase in the number of layers of cells and damages. The control plants did not exhibit any symptoms of damage. SEM-EDS analysis …

Characterization of Pharmaceutical Materials by Thermal and Analytical Methods
… and crystalline state identified by macro-photomicrography and compared to the conductivity variations. This second “empirical method” correlates well with the “activation energy” method. A comparison of overall average amorphous content by the empirical method had a linear relationship …
