aIt can be seen that during the first phase of loading, the plot of stress versus strain is a straight line, indicating that stress is directly proportional to strain. After point A on the diagram, the curve is no longer a straight line. This point is called the proportional limit. 它能...
The surrounding microenvironment limits tumour expansion, imposing a compressive stress on the tumour, but little is known how pressure propagates inside the tumour. Here we present non-destructive cell-like microsensors to locally quantify mechanical st
Ultrasonic NDE is one of the most promising methods for non-destructive diagnostics of residual stresses. However the relative change of sound velocity, which is directly proportional to applied stress, is extremely small. An initial stress of 100 MPa produces the result of δV/V∼10 −4. ...
Here we show that the polar concentration of LacY is CL-independent. The osmotic activation threshold of ProP was directly proportional to the CL content of wild type bacteria, the PG content of CL-deficient bacteria, and the anionic lipid content of cells and proteoliposomes. CL was effective...
have reported that surgical stress is the effect of an operation on the human body, and the severity of stress is proportional to the degree of tissue damage29. According to previous studies, TBI, serving as a stressor, has been found to alter the hypothalamic-pituitary-adrenal (HPA) axis30...
The rate constant of photoinhibition, measured in lincomycin-treated leaves, is directly proportional to light intensity Proc. Natl. Acad. Sci. USA, 93 (1996), pp. 2213-2218 View in ScopusGoogle Scholar [11] M.A. Jansen, A.K. Mattoo, M. Edelman D1–D2 protein degradation in the chlor...
The determination of the internal residual stress state in a material is more important than that of the surface for the subsequent strength analysis and prediction of machining deformation, but most methods cannot measure the internal residual stress state directly. In response to this problem, in ...
The final scour depth is found to be directly proportional to the difference between the initial bed shear stress because of suction and the threshold bed shear stress for the bed grains in the presence of suction. 展开 关键词:Bedforms Alluvial fans Bed load Infiltration Sediment transport ...
What Is Tempered Glass? How Does It Break? Ductile Curve When a ductile material, such as copper or aluminum, is put under stress, initially, the resulting strain is proportional to the magnitude of the forces. This is depicted by the straight-line OA. The straight-line implies that stress...
Moreover, the numerical simulations and analysis for the models of stress indicate that the luminescent time is synchronous with the stress and the emission intensity is proportional to the value of stress. To the best of our knowledge, this is the first study that the cementitious material ...
