Centrifugal forces resulting from riding a roller coaster can be a challenge to your blood pressure, as blood trends to flow to your legs instead of your carotid arteries and aorta. A similar effect takes place as you wake up every morning. How does your body cope with these sudden changes in blood pressure?

A new archaebacterium species was discovered that strives at elevated temperatures. List three differences in the membrane composition of the archaebacterium:

If the archaebacterium is normally grown at 80^oC is transferred to medium at 37^oC, give two changes (adaptations) the bacterium can make to the composition of membrane lipids. Be specific and include modifiers such as increase/decrease, etc.

Creative Financing Inc. is planing to issue a 15-year, $1,000 face value bond with a coupon rate that changes every five years.  The coupon rate for the first five years is 10%, 10.75% the next five years, and 11.5% for the remaining five years.  If the yield on this bond is 11%, how much would you be willing to pay for this bond?

1. Suppose you prepare a buffer by dissolving 0.10 mole per liter of a weak acid, HA and 0.10 mole per liter of its sodium salt, A-. Assume that pKa = 3. (a) What is the pH of the buffer? How much does the buffer have to be diluted for the pH to increase by 1 unit? Neglect changes in activity coefficients.

Corporate Culture plays a significant role in the success or failure of a security program. Find and comment on two ways that management can change corporate culture to improve the security posture of a company? Why do you believe these changes will make a difference in the corporate culture? Be sure to research outside your textbook for this and properly cite your sources.

A heavily insulated steam turbine operates steadily and is supplied with 1 kg/s steam at 2MPa, 400 deg C. If the outlet temperature is 100 deg C and the turbine has an output of 1000 kW determine the quality of the outlet steam, the rate of entropy generation and the isentropic efficiency of the turbine. (Changes in kinetic and potential energy are negligible).

Sketch the equilibrium band structure of pnp bipolar junction transistor (BJT). In point form, explain how
the application of a bias voltage at the “base” changes the band structure that you have drawn and can be
used to turn this device “on” and “off”. (a well-labeled equilibrium diagram will enable you to complete this without
any further band-structure diagrams)

1.What will be the impact on a company's profit if the sales mix shifts between low margin and high margin products? Explain different possible scenarios.

2.When does absorption costing net operating income and variable costing net operating income require reconciliation? Explain different situations with appropriate reasons behind such changes.
