Principal stress rotation as cause of cyclic mobility

Numerical Simulation of Earthquake-Induced Liquefactions Considering the Principal Stress Rotation

Dynamic loadings such as earthquake loadings can generate considerable principal stress rotation (PSR) in the saturated soil. The PSR without changes of principal stress magnitudes can generate additional excess pore water pressures and plastic strains, thus accelerating liquefaction in undrained conditions. This paper simulates a centrifuge model test using the fully coupled finite element met...

Uterine Rotation: A Cause of Intestinal Obstruction

Intestinal obstruction is an uncommon surgical emergency during pregnancy that affects seriously the prognosis of gestation. The underlying cause can be identified in the majority of cases and usually consists of adhesions secondary to previous abdominal or pelvic surgery, followed in order of frequency by intestinal volvuli. In recent years there have been no reports in which the gravid uterus...

Fault zones cause a rotation of the background stress field and can induce plastic deformations

Emotional stress as a cause of diabetes mellitus.

from the correlations occupy the final six pages. Little more is said of diabetic acidosis than that insulin administration is indicated to overcome the enzymatic defect produced by ketone formation. The authors' visualization of vomiting in diabetic acidosis as a homeostatic mechanism for the elimination of hydrogen ions is to be deplored. Tables, several with irrelevant and overly complex dat...

Pheochromocytoma as a Rare Hidden Cause of Inverted Stress Cardiomyopathy

Stress cardiomyopathy (SCMP) is characterized by a transient left ventricular dysfunction associated with apical ballooning and compensatory hyperkinesias of the basal segments after emotional or physical stress, but inverted or mid-ventricular variants of SCMP have also been described. Although catecholamine excess has been suggested as a possible pathophysiologic mechanism of SCMP, the etiolo...
