Influence of salivary PH in color stability of different flowable resins: In vitro study by Andrea Mejía, Víctor Montaño, Andrés Viteri, Ana Armas

“…Materials and methods: An experimental, comparative and in vitro study is proposed using 90 discs made from two fluid resin markings of 10mm diameter and 1mm thickness, light-cured using the same lamp, after being immersed in distilled water and made a first registration color using Easy-shade digital colorimeter, the samples were divided into three groups and in turn into three subgroups, becoming submerged in artificial saliva with different pH of 5, 6 and 7 respectively for 7 days, making a new color taking by digital colorimeter, later the samples were submerged in beet juice as a pigmenting agent for 24 hours, after this period they were washed to eliminate pigment residues and made a third color take. …”

Carbon Nanotubes: Synthesis via Chemical Vapour Deposition without Hydrogen, Surface Modification, and Application by Nguyen Duc Vu Quyen, Dinh Quang Khieu, Tran Ngoc Tuyen, Dang Xuan Tin, Bui Thi Hoang Diem

“…The obtained multiwalled CNTs exhibit a less-defective structure with an identical external diameter of tubes of around 50 nm. The growth mechanism of CNTs suggests that the Fe2O3/Al2O3 precatalyst is reduced to Fe/Al2O3 during the synthesis process using the products of LPG decomposition, and the tip-growth mechanism is suggested. …”

A Global Survey of Lunar Surface Thorium Anomalies Associated with Impact Basins by S. Nagihara

“…Therefore, the lateral variation of surface Th content is controlled mainly by the distribution of the large (≳400 km diameter) mare basins of impact origin. This first-order variation can be altered significantly by two types of processes that take place after the basin formation. …”

Symmetric single-input eccentric tube robot (ETR) for manual use by Mayer Juliane, Dumancic Marcel, Pott Peter P.

“…A model for curvature as a function of input angle is presented, and a prototype ETR with an outer diameter of 1 mm is assembled and evaluated. The results show that the ETR follows the expected shape, the curvature decreasing with the separation angle in an almost linear way that may be perceived as intuitive and predictable by the human user. …”

Analysis of Extent of Deformation Range and Failure Characteristics of Rocks Surrounding a Tunnel Crossing Fault Zone Based on FDEM by Guo Xiaoxiong, Wang Ning, Xu Xueliang, Ye Zihui

“…Analysis of the results showed that the disturbance range of surrounding rocks could reach 1.5 to 2.5 times the tunnel diameter when crossing the fault zone. The rock surrounding the tunnel was found to incur significant conjugate shear deformation and extrusion deformation: conjugate shear deformation was identified as dominant in the deep rock mass, whereas extrusion deformation prevailed in the rock mass near the cave wall. …”
