A Cross-Sectional Study on Oral Potentially Malignant Disorders: Diagnostic Challenges in Early Detection of Dysplasia and the Role of Velscope.

Background: The oral cancer burden has become a global challenge in the present scenario. Early diagnosis of oral potentially malignant disorders (OPMDs) with dysplasia is crucial to increasing the overall survival rate of the patients. Efficient chairside techniques are much needed to enhance diagnostic efficacy at early stages.

Assessment of biogrowth assemblages with depth in a seawater intake system of a coastal power station.

Marine biogrowth infestation of a seawater intake system was investigated. A digital camera fixed onto a skid was used to record the biogrowth at intervals of 5m up to a depth of 55m. Divers inspected the intake shaft and collected the biogrowth samples for biomass estimation.

Nanoparticle formation in water-in-oil microemulsions: experiments, mechanism, and Monte Carlo simulation.

The dynamics of nanoparticle formation in water-in-oil microemulsions via temporal size evolution has been followed from UV-visible absorption spectra of CdS nanoparticles. Existing Monte Carlo (MC) simulations of nanoparticle formation are primarily based on the mechanism of nuclei formation and their growth by coalescence-exchange of drops, which alone do not predict particles of large size as observed in some experiments. Hence, we have included an additional size enlargement process, namely coagulation of nanoparticles during drop coalescence.
