[1] Taiwan’s Hsüehshan range experienced penetrative coaxial deformation within and near the brittle-plastic transition between 6.5 and 3 Ma. This recent and short-lasting deformation in an active, well-studied orogen makes it an ideal natural laboratory for studying crustal rheology. Recrystallized grain size piezometry in quartz and Ti-in-quartz thermobarometry yield peak differential stresse...

OBJECTIVE The purpose of this study was to analyze stress distributions in the roots, periodontal ligaments (PDLs), and bones around cylindrical and tapered miniscrews inserted at different angles using a finite element analysis. METHODS We created a three-dimensional (3D) maxilla model of a dentition with extracted first premolars and used 2 types of miniscrews (tapered and cylindrical) with...

The strut-and-tie model (STM) method is useful for the limit state design of reinforced concrete (RC) corbels. However, rational RC corbels, designers must accurately determine strengths struts and nodal zones to check strength conditions a selected STM anchorage reinforcing bars in zones. In this study, authors suggested numerical process determining corbel STMs. technique incorporates two-dim...

In this study, the effect of various materials used in fabricating superstructures for implant-retained fixed partial dentures on stress distribution around implant tissues was investigated. Five different mathematical models consisting of 11,361 nodes and 54,598 elements were constructed to study porcelain, gold alloy, composite resin, reinforced composite resin, and acrylic resin veneering ma...

The effect of forced near-inertial motion on the kinetic energy budget of a turbulent, geostrophic background flow is examined using a primitive equation ocean circulation model. Balanced and unbalanced parts of the flow are taken to be equivalent to lowand high-passed filtered versions of the model fields, and the Reynolds stresses associated with the high-passed, predominantly near-inertial p...

Mud peeling is a common phenomenon whereby horizontal cracks propagate parallel to the surface of a drying clay. Differential stresses then cause the layer of clay above the crack to curl up to form a mud peel. By treating the clay as a poroelastic solid, we analyse the peeling phenomenon and show that it is caused by the gradient in tensile stress at the surface of the clay, analogously to the...

The presented studies confirmed stress formation patterns in concrete supports, which are the sum of gravitational, tectonic, and variable components, especially areas with active geodynamics. problem underground workings lining reliability is due to need solve problems determining stress-strain state level, taking into account all listed components forces strength properties. main parameters t...

The splitting of the frequencies of p-modemultiplets enables information to be gained about the internal rotation of the sun. Such data have revealed a transition at the base of the convection zone from differential rotation similar to that observed at the surface to almost solid-body rotation in the radiative interior. This transition region, known as the tachocline, has been found to be relat...
