The government of Ivarrona has put in place an advanced telecommunications network that can support upload and download speeds of 1 gigabit (roughly 100 times faster than today’s average internet speeds). They are now ready to launch a Telemedicine service that will allow physicians to reach and treat (where possible) patients that cannot reach a doctor’s physical location or a hospital easily. They are ready to roll out a special package called ‘i-MediConnect’ consisting of a laptop, a high quality digital camera and a microphone system that can be plugged into any handheld device or laptop (it can run on Windows, MacOS, Linux, etc. and works on almost all major platforms). They plan to distribute this free to all physicians and clinicians (and to hospitals) that will participate in the program. They also plan to install these in thousands of special purpose kiosks built all over the country (Ivarrona). In addition to the i-MediConnect package, these Kiosks will also have devices that can capture many important elements of patient vitals – including blood pressure, A1C levels, body temperature, etc. (assume that it can do some body fluid capture and analysis too).

The total cost of manufacturing n Kiosks by the government is given by: 100 + 2√n

The total cost of setting up m Kiosks by the government is given by: 50 + (m/4)

Answer the following questions based on the information above. Sample Question 2 (a): Only one of the following alternatives is correct. Identify the correct alternative.

1. The manufacturing of these Telemedicine Kiosks is characterized by scale economies.
2. The average cost of manufacturing n units of the kiosk is increasing in n.
3. The total cost of manufacturing n units of the kiosk is decreasing in n.
4. The average cost of manufacturing n units of the kiosk is constant (neither increasing nor decreasing in n).

A third-party company offers to manufacture and set up, up to 10,000 Kiosks for a total fixed fee of 2750 (disregard currency units). Thereafter, for additional Kiosks it will charge a combined fee (of manufacture and set up). This fee for K kiosks is given by: F(k) = 150 + (k/2). The government expects that it will need 40,000 Kiosks in all. Should the government take the third-party company up on its offer?

Assume the economy has a GDP of $11,500 billion. The unemployment rate is at 7.3% and has been slowly rising for the last 6 months. Inflation was at 2.3% one year ago but has since dropped to near 0%. The MPC in the economy is .80 and the Natural Rate of Unemployment is 4.5%. The target rate for inflation is 2%.

1. Why would it be better for government to solve the problem using government purchases (part c above) rather than taxes (part d above) to solve the problem?
2. Assuming that government does decide to use the tax policy, what could happen to cause the policy to be ineffective?

Trace metals found in wells affect the taste of drinking water, and high concentrations can pose a health risk. Researchers measured the concentration of zinc (in milligrams/liter) near the top and the bottom of 7 randomly selected wells in a large region. The data are provided in the following table. Construct and interpret a 90% confidence interval for the true mean difference (Bottom – Top) in the zinc concentrations of the wells in this region.

A. The electric potential at a position located a distance of 19.2 mm from a positive point charge of 7.80×10^-9C and 13.0 mm from a second point charge is 1.14 kV. Calculate the value of the second charge.

B. The potential difference between two parallel conducting plates in vacuum is 590 V. An alpha particle with mass of 6.50×10^-27 kg and charge of 3.20×10^-19 C is released from rest near the positive plate. What is the kinetic energy of the alpha particle when it reaches the other plate? The distance between the plates is 45.0 cm.

Closing is subject to buyer’s inspection of property by him and his designated specialist and complete satisfaction of specialist with property condition. Aherns’s specialist inspected the property and said he thought the roof would need to be replaced in a few years. He also felt some wood near the front of the cabin should be replaced. Aherns demanded that the Johnsons fix these items or he would not close. The Johnsons maintain they did not agree to any repairs; the condition was for Aherns’ protection so that he could opt out of the agreement. Aherns has threatened to sue for breach of contract. Who should win?

Determine the chimney height required to preserve design flow in a natural recirculation boiling water reactor channel with the following characteristics:

System pressure: 7.136 MPa

Reactor height 1.83 m

Feedwater temperature 260 Celsius

Combined pressure in losses in the channel, chimney, and downcomer: 1344.5 Pa

Average channel density in the core: 642.9 kg / m^3

Two-phase friction losses in the chimney 137.9 Pa

Friction losses in the downcomer: 68.9 Pa

Friction drop in channel: 606.7 Pa

Average exit void fraction: 44%

Feedwater added near the top of chimney

1) Describe what polarization means in the context of electric charges. Generally, under what circumstances would I see polarization happen? (describe how the charges are distributed pre- and post- polarization). Water is said to be a polar molecule; what does that mean in this context?

2) Plasma is a state of matter that has been completely ionized; meaning that there are no electrons bound to protons, and both the electrons and protons are able to move about freely. If I have a positively charged surface and bring it near to a plasma, what would happen? Will both the electrons and protons behave in the same way? (compare their accelerations).

3. A pregnant woman has come to you for advice. By mistake she took thalidomide prescribed for her husband. She is certain that she took the drug during the third week of pregnancy, she is now near the end of the second trimester. She has come to you to determine whether her child will be born with malformed limbs.

a. Explain what test or tests you would suggest that could answer her question.

b. Explain why you choose that test.

c. What results would you expect from your test if the fetus was affected.

PLEASE BE SPECIFIC

Once researchers learn about some aspect of cancer or its treatment, clinical trials are needed to test out any proposed use in humans. What are some of the kinds of clinical trials going on for cancer? Go to the National Cancer Institute's website and look at their web page with the title Search for Clinical Trials. Select a form of cancer and look for clinical trials near you. Pick one of the trials that is currently open to new participants. Explain who is participating and what is the trial testing, Who is excluded from participation? What phase of trial is this study and what are they mainly trying to find out?
