The challenge for companies to be competitive is to reach international markets. To explore foreign market, 10 countries were selected from each of four global regions. The data on the cost associated with importing a cargo of goods by sea transport in these countries (in US$ per container) was collected.

Miller Model with Corporate and Personal Taxes

Cruz Corporation has $100 billion of debt outstanding. An otherwise identical firm has no debt and has a market value of $450 billion. Under the Miller model, what is Cruz’s value if the federal-plus-state corporate tax rate is 28%, the effective personal tax rate on stock is 17%, and the personal tax rate on debt is 29%? Enter your answer in billions. For example, an answer of $1.23 billion should be entered as 1.23, not 1,230,000,000. Round your answer to two decimal places.

Black body (b) and purple eye (pr) are recessive autosomal mutations in Drosophila. Bridges crossed b/b females and pr/pr males. F2 cross produced 684 wild-type, 371 black-bodied, and 300 purple-eyes flies. Do these result indicate that the b and pr genes are closely linked? Explain. Remember that there is no crossing over in male Drosophila

What new technologies were important in the history of bridges?

Why did the Romans use elevated aqueducts instead of pipes to convey their water?

Which of the Grand Challenges for the 21st century do you believe is most important? why? which challenge do you believe to be the least important? why? what challenges do you believe should be added to the list why?

1. a) Huygens' Principle. Pick a type of propagation of waves that light rays don't exhibit. Several to pick in the notes. On a sheet of paper, graph the starting wavefront of your choice, and continue with the Huygens' Principle construction of at least 4 additional wavefronts. Does it look like the wave movement can not be described as a ray?

b) Name and describe one of the three processes mentioned that allow you to calculate intensity profile on a viewing screen behind a single slit screen.

c) You perform two experiments with a given laser: First with a single slit of width 1 mμ, and the other with two very narrow slits spaced also by 1 mμ. The viewing screen is two meters away. What will be larger, the width of the central maximum in the single-slit experiment, or the distance between the central maximum and the neighboring maximum in the double-slit experiment? Explain.

d) A pinhole camera is a closed cube that has a pinhole in the center of the front wall and a film on the back wall. If the side of the cube is 10 cm, how wide should the pinhole be for camera not to exhibit significant diffraction effects?

e) What was the principal equipment used in the Michelson-Morley experiment, and what was the conclusion of the experiment?

Consider a concentration cell. Two Ag-electrodes are immersed in AgNO3 solutions of different concentrations. When the two compartments have an AgNO3-concentration of 1 M and 0.1 M, respectively, the measured voltage is 0.065 V (note: T in not necessarily = 25°C !).

a. What is the voltage, if the two compartments have AgNO3-concentration of 1 M and 0.01 M, respectively?

The electrochemical behavior of silver nanoclusters (Agn, with n the number of Ag atoms in the cluster) is investigated using the following electrochemical cells at 298 K:
I. Ag(s) | AgCl (saturated) || Ag+(aq, 0.01M) | Ag(s), E=0.170
II. (Pt electrode) Agn (s, nanocluster) | Ag+(aq, 0.01M) || AgCl (saturated) | Ag(s), with E = +1.030 V for Ag5 nanocluster and E = +0.430 V for Ag10 nanocluster

The standard reduction potential for Ag+ + e- → Ag, is E0 = +0.800 V.

b. Use this data to calculate the solubility product of AgCl.

The two nanoclusters Ag5 and Ag10-nanoclusters have standard potentials different from the potential of metallic bulk silver.

c. Calculate the standard potentials of Ag5 and of Ag10 nanoclusters. [for this part use Ksp(AgCl)=1.800·10-5; this is not the same value as calculated in b.]

d. What happens, if you put the Ag10 nanoclusters and – in a second experiment – the Ag5 nanoclusters into an aqueous solution of pH=5? Estimate the consequences using the reduction potentials you calculated.

Week 3 Case Study, Information Literacy: A Road to Evidence-Based Practice

Nursing student Melissa is working on her patient care plan for this week’s clinical experience. Melissa remembers being told in class that when considering patient outcomes, the nurse must consider evidence-based practices to serve as the basis of nursing care and that the nurse’s level of education and practice will reflect in different interventions.

What process will Melissa use as the standard to investigate evidence-based care to include in her patient’s care plan?

What examples can Melissa provide to demonstrate how BSN, MSN, and Doctorate prepared nurses utilize evidence-based practice interventions differently?
