This study aimed to theoretically evaluate soil thrust on a clay slope as reaction force associated with the motion of an off-road tracked vehicle. The existing concept potential failure modes block flat ground has extended determine sloped ground. Based upper-bound limit analysis, under most critical was derived for three modes: block, triangular-wedge, and trapezoidal-wedge failures. Specific...

Electrical currents in resistive materials must be driven by an internal electric field E = J/ς , where J is the current density and ς is the electrical conductivity. The internal electric field must be shaped by an appropriate density σ of surface electrical charge. In practice, the surface charge density is quite small, and is often neglected in discussions of electrical currents. Some except...

By conducting wedge-growth accounting, we assess the contribution of economic forces (expressed as wedges in equilibrium conditions neoclassical growth model) driving Spanish from 1850 to 2019. We find that declining investment and capital-efficiency slowed down downsized labour share First World War. The crisis 1930s (Great Depression Civil War) was primarily driven by decrease labour-efficien...

BACKGROUND Computer assisted corrective osteotomy of the diaphyseal forearm and the distal radius based on computer simulation and patient-specific guides has been described as a promising technique for accurate reconstruction of forearm deformities. Thereby, the intraoperative use of patient-specific drill and cutting guides facilitate the transfer of the preoperative plan to the surgery. Howe...

INTRODUCTION This study quantified bone removed to correct three different sizes of posterior glenoid defects and also quantified the change in rotator cuff muscle length resulting from correction of each defect using three different glenoid designs. METHODS A 3-D computer model quantified the cortical and cancellous bone removed when correcting three sizes of posterior glenoid defects and si...

[1] Orogenic structure appears to be partially controlled by the addition to and removal of material from the mountain belt by tectonic accretion and geomorphic erosion, respectively. We developed a coupled erosion-deformation model for orogenic wedges that are in erosional steady state and deform at their Coulomb failure limit. Erosional steady state is reached when all material introduced int...

The extendibility of CR functions on smooth real manifolds in C has been extensively studied by many specialists (see, e.g., [Bo] for references). In this paper we generalize the results of [T1] and [T2] on the extendibility of CR functions to manifolds with boundaries and edges. Recall that a generic manifold M ⊂ C is said to be minimal at p ∈ M if there is no proper CR submanifold S ⊂ M passi...

BACKGROUND Medial opening wedge high tibial osteotomy (HTO) is a well-established surgery for medial compartment knee osteoarthritis (OA) wherein the lower extremity is realigned to shift the load distribution from the medial compartment of the knee to the lateral compartment. However, this surgery is known to affect the posterior tibial slope angle (PTSA), which could lead to abnormal knee kin...

In order to assess the role of right ventricular and left ventricular dysfunction in patients with cardiogenic shock associated with combined right ventricular and inferior myocardial infarction, we reviewed the clinical records and haemodynamic data of 18 patients with inferior myocardial infarction and cardiogenic shock. Six of these patients had haemodynamic evidence of right ventricular dys...

BACKGROUND Stepped wedge cluster randomised trials frequently involve a relatively small number of clusters. The most common frameworks used to analyse data from these types of trials are generalised estimating equations and generalised linear mixed models. A topic of much research into these methods has been their application to cluster randomised trial data and, in particular, the number of c...
