BACKGROUND Axial dynamization of fractures can promote healing, and overly stiff fixation can suppress healing. A novel technology, termed active plating, provides controlled axial dynamization by the elastic suspension of locking holes within the plate. This prospective, controlled animal study evaluated the effect of active plates on fracture-healing in an established ovine osteotomy model. W...

The physical mechanism underlying ENSO’s phase locking to the seasonal cycle is examined in three parameter regimes: the fast-SST limit, the fast-wave limit, and the mixed SST–wave dynamics regime. The seasonal cycle is imposed on simple ordinary differential equation models for each physical regime either as a seasonal ocean– atmosphere coupling strength obtained from the model of Zebiak and C...

The two-phase gas-liquid flow properties of high-velocity open channel flows were studied experimentally in a large-size channel. The physical facility was equipped with a succession of triangular cavities associated with some strong interactions between air entrainment and flow turbulence. Detailed air-water flow measurements were collected with intrusive phase-detection probes for several flo...

Compound casting is a process in which single component made from two metallic materials, such as aluminum and steel. Solid-liquid bimetallic compounds can be produced by suitable control. This technology reduce the number of joining processes, specific properties respective metal used for specifically designed product properties, example, where lightweight high strength are needed. paper prese...

Abstract Faults represent a critical heterogeneity in basaltic sequences, yet few studies have focused on their architectural and hydromechanical evolution. We present detailed, multi-scale characterization of passively exhumed fault zones from the layered basalts Faroe Islands, which reveals cyclic stages Outcrop-scale structures rock distribution within were mapped field 3-D virtual outcrop m...

The paper presents a locking-free four-node element for laminated composite and sandwich plates based on Refined Zigzag Theory (RZT). Initially, two RZT-based plate elements are derived using eight-node configurations, achieved by way of standard C0 isoparametric shape functions. In addition, with view improving the modelling extremely thin plates, an anisoparametric is developed in which trans...

In this paper, an instability analysis of three-dimensional (3D) beams supported with 3D hinges under axial and torsional loadings is presented in the large displacement rotation regime. An exact field proposed based on central line orientation cross section consisting nine parameters corresponding to centroid movements rotations. The Cauchy–Green deformation tensor derived local coordinate sys...

Quantitative evaluation of shear stress in the vessel wall due to the presence of asymptomatic gas emboli is lacking. The goal of this work was to assess the impact of chronic asymptomatic gas emboli on the risk of atherosclerosis through a custom-built cardiovascular flow simulator. Gas bubbles were created by forced air from a syringe pump. The influences of embolism injection rate, pulse rat...

The hydraulic stability of rocks and other non-cohesive sediments is often described by so-called threshold conditions. These conditions describe the stability of the stones in terms of critical values of the velocity, wave height, or shear stress. The influence of fluid accelerations in most of these conventional design methods has been neglected or has been processed empirically. For various ...

A comparison equation is set up and solved for the locking of an electronic angular momentum 1 = 1 to the molecular axis during a collision of two atoms. Two parameters which enter into the comparison equation characterize the strength and the abruptness of the locking. A solution found allows one to investigate the transition from loose locking to tight locking. A new definition of the locking...
