Abstract Rock anchors are used to stabilise large-scale infrastructure such as the foundations of high buildings or road cuts, and their failure could lead severe economic social consequences. A rock anchor can fail in one more following four modes; breakage tendon steel, tendon-grout bond failure, grout-rock mass failure. In current design, knowledge for first two modes is satisfactorily known...

introduction: nager syndrome is a malformation resulting from problems in the development of the first and second branchial arches and limb buds. the cause of the abnormal development of the pharyngeal arches in nager syndrome is unknown. it is also unclear why affected individuals have bone abnormalities in their arms and legs. nager syndrome is thought to have an autosomal recessive inheritan...

Trakošćan Castle, built on a rocky peak in the late 13th century, is cultural heritage site protected as historical entity by Republic of Croatia. The Castle constructed highly irregular masonry structure with timber or shallow arches, vaults dome floors. It was substantially renewed, upgraded and partially retrofitted from 16th century until year 2000. M5.5 (VIII EMS) M6.2 (VIII-IX earthquakes...

Geological radar is an important method used for detecting internal defects in tunnels. Automatic interpretation techniques can effectively reduce the subjectivity of manual identification, improve recognition accuracy, and increase detection efficiency. This paper proposes automatic approach geological images (GPR) based on YOLOX-s, aimed at accurately steel arches any direction. The utilizes ...

Abstract. The method for identifying the line of thrust closest to geometrical axis an undamaged arch, developed by authors in a publication 2019 first time, is extended this paper case cracked arches. Cracks subdivide arch into rigid portions linked in-between correspondence points at extrados or intrados, which can be interpreted as internal hinges. Under assumption, procedure reformulated an...

BMP signaling is essential for a wide variety of developmental processes. To evaluate the role of Bmp2/4 in cranial neural crest (CNC) formation or differentiation after its migration into the branchial arches, we used Xnoggin to block their activities in specific areas of the CNC in transgenic mice. This resulted in depletion of CNC cells from the targeted areas. As a consequence, the branchia...

Objectives: To determine the prevalence of malocclusion in a group of 3,466 children aged 7 to 12 years enrolled in public schools in the cities of Lins and Promissão, in the state of São Paulo, Brazil. Methods: The sagittal relationships between dental arches, the transverse relationship between arches, and the vertical and horizontal relations of incisors were analyzed. The prevalence of dias...

The Galactic center harbors some of the most massive star clusters known in the Galaxy: the Arches and the Quintuplet. Based on the Chandra observations of these clusters (PI: Wang) which recently became public, I discuss the X-ray emission from the massive stars in these clusters. Confirming the general trend for Wolf-Rayet (WR) stars being X-ray dim, none of them is detected in the Quintuplet...
