Research on the Mechanical Analysis of Weathered Rock Filling Subgrade on Highway
With the rapid development of national economic construction, traffic network is extending continuously, and the scope of the highway construction is gradually shifting from plain to the mountains. However, weathered rock occupies heavily along highway in mountainous area, and high quality subgrade filling is extremely short, thus a large amount of subgrade filling needed for subgrade high-fill...
متن کاملChitinophaga qingshengii sp. nov., isolated from weathered rock surface.
A novel mineral-weathering bacterium was isolated from weathered rock (potassic trachyte) surfaces collected from Nanjing (Jiangsu, PR China). Cells of strain JN246(T) were Gram-stain-negative, rod-shaped and non-motile. Strain JN246(T) was aerobic, catalase- and oxidase-positive, and grew optimally at 28 °C and pH 7.0. On the basis of 16S rRNA gene sequence analysis, strain JN246(T) belonged t...
متن کاملDraft Genome Sequence of Rhizobium sp. H41, a Rock-Weathering Bacterium from a Weathered Rock Surface
Rhizobium sp. H41 isolated from weathered tuff can weather tuff and release Fe, Si, and Al from the rock under nutrient-poor conditions. Here, we report the draft genome sequence of strain H41, which may facilitate a better understanding of the molecular mechanism involved in rock weathering by the bacterium.
متن کاملEvaluating the Effect of Dental Filling Material and Filling Depth on the Strength and Deformation of Filled Teeth
ackground and aim: It is important to evaluate the effect of the type of filling material on deformation and strength of tooth after filling and also the effect of filling depth on quality of restoration of a decayed tooth. Material and Methods: The Orthopantomogram (OPG) of the first and second molars of a 28-year-old man was made and the teeth were 3D modeled. The stress-deformation analysis ...
متن کاملSystematic review of "filling" procedures for lip augmentation regarding types of material, outcomes and complications.
BACKGROUND The ideal lip augmentation technique provides the longest period of efficacy, lowest complication rate, and best aesthetic results. A myriad of techniques have been described for lip augmentation, but the optimal approach has not yet been established. This systematic review with meta-regression will focus on the various filling procedures for lip augmentation (FPLA), with the goal of...
