Effect of staining and repeated firing on the surface and optical properties of lithium disilicate
(2020-01-01)
Objective: Evaluate the effect of staining and repeated firings on color, translucency and surface proprieties of CAD/CAM lithium disilicate (LD). Material and Methods: One hundred eighty LD discs were made (ISO 6872) and ...
Effect of Consecutive Firings on the Optical and Mechanical Properties of Silicate and Lithium Disilicate Based Glass-Ceramics
(2021-01-01)
Purpose: To evaluate the effect of multiple firings on the optical and mechanical properties of two dental CAD/CAM glass-ceramics. Materials and Methods: A total of 45 specimens of each lithium disilicate-LD (IPS E.max ...
Effect of repeated firings and staining on the mechanical behavior and composition of lithium disilicate
(2020-05-01)
Objective: To evaluate the composition, flexural strength and fatigue behaviour of lithium disilicate ceramic (LD) after repeated firings and different staining techniques. Methods: LD discs were fabricated and divided ...
Frequent fires do not affect sexual expression and reproduction in Vachellia caven
(Wiley Blackwell Publishing, Inc, 2019-06)
In environments with high fire frequency the impoverishment of abiotic resources may favor male sexual expression in plants as it is less costly than female expression. Also, fire can modify pollinator communities and thus ...
Modulation of Fire Regimes by Vegetation and Site Type in Southwestern Patagonia Since 13 ka
(Frontiers Media SA, 2018-04)
The degree to which vegetation and site type have influenced fire regimes through the Holocene has not been investigated in detail in the temperate ecosystems of southern Patagonia. Here we present a first attempt using a ...
COLOR STABILITY OF DENTAL CERAMICS SUBMITTED TO ARTIFICIAL ACCELERATED AGING AFTER REPEATED FIRINGS
(MOSBY-ELSEVIER, 2009)
Statement of problem. Color stability is an important factor to ensure the long-term clinical success of ceramic restorations. There is a lack of information on how color is affected by fabrication procedures, such as the ...

Avaliação de áreas queimadas no Parque Nacional das Sempre-Vivas MG: contribuições para a implantação do manejo integrado do fogo
(Universidade Federal de Minas GeraisUFMG, 2016-06-10)
The fire presence in protected areas, especially those inserted in the Cerrado, is constituted as a great challenge for managers. Since the creation of the Brazilian Protected Areas (PA), the zero fire policy has been ...
