To obtain a more detailed description of the stress-free state of the intestinal wall, longitudinal residual strain measurements are needed. Furthermore, data on longitudinal stress-strain relations in visceral organs are scarce. The present study aims t
Another interesting idea is to distribute rotations between joints in a way similar to the actual rotations of the spine, where a single vertebra has a maximum possible range of rotation. The rotation starts with the lowermost vertebra and continues until its maximum range has been reached. At ...
a In the case of a uniaxial state of stress (σ11 ≠ 0, σ22 ¼ σ33 ¼ 0), the constitutive relation can be rewritten in terms of longitudinal stress and strain components only as 在一个单轴的状态重音 (σ11 ≠情况下0, σ22 ¼ σ33 ¼ 0),结构性联系可以被重写根据纵向应力...
An elastic isotropic body with a thin internal ″tunnel″ crack is considered. It is subject to the action of shearing forces changing in time in accordance with the harmonic law. This case is also known as pure shear or antiplane deformation. The problem is reduced to a mixed boundary ...
. The main disadvantages are the greater expense of repeated study, the possibleHAWTHORNE EFFECTof repeated studies and the influence of other changes which may be occurring concurrently (e.g. changes in the school curriculum may take place at the same time as changes in the resourcing of ...
Prior research has explored various factors to explain differences in teaching experiences and behaviors among school teachers, including self-efficacy, ba
First, the ASE/EACVI recommendations acknowledge the importance of an integrated approach in the early diagnosis of CTRCD combining changes in strain parameters with circulating troponin levels.5 The incremental value of this approach is discussed in some studies12,31,40 but could not be explored ...
Since PDs are usually lifelong patterns of behavior and were assessed only once in this survey, we were only able to examine the relationship between PDs and income cross-sectionally; thus, we can draw limited conclusions and cannot make any causal inferences. It is possible that individuals in...
To longitudinally assess left ventricle (LV) global longitudinal strain (GLS) and hemodynamic forces during the early stages of cardiac dysfunction in a mouse model of heart failure with preserved ejection fraction (HFpEF). Cardiac MRI measurements were performed in control mice (n = 6), and...
On the initiation of top-down cracking, there are two opinions. First, one opinion is that the cracks are caused by the tensile stress/strain on the pavement surface. In 1984, Molenaar [21] analyzed the effects of the lateral and vertical contact stresses between pavement and tire on ...
