A wide loaded area carries a net uniformly distributed pressure q = 150 kPa on a soil profile that consists of 3 layers [4 m sand (20 kN/m³) over 2 m clay (18 kN/m³) over 3. m sand]. The water table is at the top of clay layer. The permeability of sand is very large. Cv = 0.50 m2/year; Calpha= 0.05; eo = 1.00. Compute the settlement due to secondary compression after 60 years.

Suppose you are working in an organization that encourages employees to participate in workshops and seminars for professional development. You are responsible for approving reimbursement expenses. To participate in this activity, employees must travel away from the organization, spend a few days, spend money from their pockets, and then turn in a report to get reimbursement for expenses. For employees, it is sometimes easy to let the numbers slip a little if the guidelines for on-the-road expenditures in the organization...

A drug response curve describes the level of medication in the bloodstream after a drug is administered. A surge function S(t) = Atpe−kt (where t > 0) is often used to model the response curve, reflecting an initial surge in the drug level and then a more gradual decline. If, for a particular drug, A = 0.03, p = 4, k = 0.03, and t is measured in minutes, estimate the times t corresponding to the inflection points. (Round your...

Researchers designed an experiment to study the effects of caffeine withdrawal. They recruited 11 volunteers who were diagnosed as being caffeine dependent to serve as subjects. Each subject was barred from coffee, colas, and other substances with caffeine for the duration of the experiment. During one 2-day period, subjects took capsules containing their normal caffeine intake. During another 2-day period, they took placebo capsules. The order in which subjects took caffeine and the placebo was randomized. At the end of...

In a closed container, one gram of water (1 cm3) is boiled under constant pressure of 1 atm (1.013 × 105 Pa) until it changes into steam. The heat of vaporization at this pressure is Lv = 2.256 × 106 J/kg = 2256 J/g. Assume that water vapor behaves like an ideal gas. The temperature of the steam is 373 K, number of moles of water vapor n = 0.0546 (g mol), the ideal gas constant R = 82.057 (cm3·atm/g...

To reduce costs, a medical lab will pool blood to conduct one single test for the prevalence of a relatively rare disease. Assume that 25 people had their blood drawn. Since the disease is relatively rare (only 2 in 100 people have the disease), the lab takes a portion of each person's blood and pools the blood together. Then the lab conducts one test of the pooled blood. If the test is negative, then the lab personnel can conclude that...
