Specific designs are achieved for producing minimum weight shell structures that will support a specified uniform pressure assuming both the Mises and the Tresca yield criteria along with the rigid-perfectly plastic flow condition.
Tropism may be important when considering an evolutionary perspective; changing sexual behaviors [ 36– 39] may have created evolutionary pressure, assuming some level of genotype competition, favoring less tropic species.
When flow is obstructed via "wedging" of a catheter in a hepatic vein, the measured pressure should equal the portal pressure (assuming no anastomoses between the vessels of the wedged liver segment and vessels with low pressure).
Therefore, in the following also arterial flows are treated as functions of arterial pressure, assuming that peak arteriolar distending pressure at the upstream end of the arterioles, corresponds to arterial distending pressure.
Trial-level associations for both systolic and diastolic blood pressure reduction and cardiovascular mortality and all-cause mortality relative risk reduction were extremely poor, less than 0.15 for systolic and 0.05 for diastolic blood pressure, assuming no measurement uncertainty.
blood pressure: assuming a standard deviation of 11, a sample size of 228 will be sufficient to detect a mean difference of 3 mmHg in systolic blood pressure between intervention and control groups.
These STEs for systolic and diastolic blood pressure assume that the new trial measuring only the surrogate endpoint is otherwise similar to past trials used in the predictive model regarding intervention, population, trial design and pharmacologic therapy.
