Background: Amelogenesis imperfecta is a rare developmental disorder.This condition can be quantitative as the hypoplastic type or qualitative as the hypomineralized hypomatured type.Case Report: This is the first clinical reported case in a 14-year-old Libyan female.It describes the oral management of hypoplastic amelogenesis imperfecta using a no
The use of biotechnology to explore low-grade ore deposits and mining tailings is one of the most promising alternatives to reduce environmental impacts and costs of copper extraction.However, such technology still depends on improvements to be fully applied in Brazil under industrial scale.In this way, the bioleaching, by Acidithiobacillus ferroox
Plasmonic nanostructures, particularly of noble-metal Au and Ag, have attracted long-lasting research interests because of their intriguing physical and chemical properties.Under light excitation, their conduction electrons can form collective oscillation with the electromagnetic fields at particular wavelength, leading qf1510 to localized surface
In the process of extension sleeve press-fitting of the bearing pressing machine, electro-hydraulic servo system of valve-controlled symmetrical cylinder (ESSVSC) is an important and critical control module, and its performance has a significant impact on the working accuracy of such equipment.People have proposed various related control algorithms
