11. Polymeric Outdoor Insulators - A Long-term Study
Sammanfattning : The long-term performance and the material state of polymeric insulators were examined from December 1987 to February 1997. To a large extent the study was conducted at Anneberg field station, on the west coast of Sweden. The project comprised a great number of commercially available polymeric insulators from several prominent manufacturers. LÄS MER
12. Early restorative rehabilitation of children and adolescents with amelogenesis imperfecta
Sammanfattning : Amelogenesis imperfecta (AI) is a rare, genetically determined defect in enamel mineralization. Patients with (AI) can present with rapid tooth loss or fractures of enamel and dental sensitivity as well as alterations in enamel thickness, color, and shape. These factors may compromise esthetic appearance and masticatory function. LÄS MER
13. Mechanical and Microstructural Properties of Monolithic Zirconia
Sammanfattning : Zirconia has been widely used in dentistry to improve the strength of ceramic restorations maintaining aesthetics. In addition, zirconia is increasingly being used for monolithic crowns without veneering porcelain. LÄS MER
14. Estimation of hydrophobicity of insulating surfaces by studying sessile water drops
Sammanfattning : Today, the traditional insulator materials for high voltage powerlines, i.e. glass and porcelain, are gradually being replaced with new materials, most notably silicone rubber. LÄS MER
15. Cobalt-Chromium alloys in fixed prosthodontics
Sammanfattning : Gold and its alloys have been the dominant framework materials in metal-ceramic constructions when substantial loss of tooth substance or missing teeth needs to be replaced. However, base metal alloys, such as cobalt-chromium (Co-Cr), have been introduced due to increased gold price. LÄS MER
