Physiological Changes in Teeth as a Tool to Estimate Age
With increasing age there are many changes in teeth such as attrition, peridontal disease, deposition of secondary dentine, root translucency, cementum apposition, root resorption, color changes, and increase in root roughness. By taking into consideration these secondary changes in teeth with advancing age, various studies were done to estimate the age of an individual. Such research has resul...
متن کاملChanges in Physiological Properties as a Criterium for Detection of Plasmid Loss in Bacillus thuringiensis
Recent technological improvements have extended the application range of dielectric permittivity biomass measurements to on-line monitoring of physiological changes during bacterial fermentations. In an industrial fermentation of Bacillus thuringiensis, it is important to verify the intactness of bacterial plasmid content in all steps of culture. Changes in certain plasmid resident properties o...
