Flow stress curve
WebAtherosclerosis is an inflammatory disease initiated by endothelial activation, in which lipoprotein, cholesterol, extracellular matrix, and various types of immune and non-immune cells are accumulated and formed into plaques on the arterial wall suffering from disturbed flow, characterized by low and oscillating shear stress. Foam cells are a major cellular … WebOther curves may be biased more toward the calm side. What matters is identifying what your curve looks like, and then becoming a master of turning up or down the dial. Emotions. Stress doesn’t occur in a vacuum of neurochemicals and hormones. It contains emotions, feelings, thoughts, and everything that comes with that. It’s experiential.
