1. What kind of nuclear units were affected in the Fukushima accident?
2. What are the fission products produced in nuclear reactors like Fukushima and Chernobyl?
3. What happened to the nuclear fuel rods in the units 1-4 at Fukushima? How does this compare to Chernobyl?
4. What happened to the spent fuel rods in these units?
5. Which of the four units do you think is the one that poses the biggest danger (for the next million years)? Give reasons.
6. What is the radiation dosage at the edge of the closed zone today at Chernobyl and how does it compare to the dosage at Fukushima? You should look up the wikipedia entry on Chernobyl Exclusion Zone. A nice account of a trip to Chernobyl is given here: http://www.pureearth.org/blog/virtual-tour-of-chernobyl/. How long do you think that these closed zones will be needed? Give reasons.

Explain why each of the following statements is True, False, or Uncertain according to economic principles. Use diagrams where appropriate. Unsupported answers will receive no marks. It is the explanation that is important.
A6-1. An economy with a recessionary gap will never return to long run equilibrium without policy intervention.
A6-2. In a closed economy, investment will equal the sum of private saving and government saving.
A6-3. An increase in private saving for a closed economy implies lower consumption in long-run equilibrium and also leads to lower GDP growth.
A6-4. You have two Canadian dimes. One is from 1962 and contains 25 cents worth of silver; the other is from 2013 and contains no silver. You would clearly use the later coin when paying for a coffee rather than the earlier one.

A company has stores in different countries. The CEO is not sure about the profitability of three stores. The following table includes the revenues and costs of these three stores in the year ended (in euros) :
|
€ |
Paris |
Vienna |
Dublin |
|
Sales revenue |
300 000 |
500 000 |
750 000 |

Cost of sales |
225 000 |
380 000 |
620 000 |

68 300 |
135 000 |

Allocated head office costs |
36 000 |
45 000 |
50 000 |
Should any of the stores be closed as soon as possible? Choose the appropriate decision for each store on the assumption that closing one store will not affect any other stores and total head office costs would not decrease if any of the stores were closed.
1) Paris
close or continue
2) Vienna

3) Dublin

An experiment was done to see whether open-book tests make a difference. A calculus class of 48 students agreed to be randomly assigned by the draw of cards to take a quiz either by open-notes or closed-notes. The quiz consisted of 30 integration problems of varying difficulty. Students were to do as many as possible in 30 minutes. The 24 students taking the exam closed-notes got an average of 15 problems correct with a standard deviation of 2.5. The open-notes crowd got an average of 12.5 correct with a standard deviation of 3.5. Assume that the populations are approximately normal. At the 5% significance level, does this data suggest that differences exist in the mean scores between the two methods?

1) Please define the term closed circulatory system. Which animals have it, and what are its’ evolutionary advantages over open systems (why might a closed system be more efficient)?
(10 points)
2) Describe all the events (steps) that occur during a cardiac cycle for mammals (organisms with a
double circulation), as well as the opening and
closing of all heart valves, and the signals arising from the SA and AV nodes. How does this cycle contribute to metabolic homeostasis for our cells, and what is the purpose of the valves?
3) Using information discussed during our lectures thus far, propose 2 physical ways that a human may develop hypertension
(abnormally elevated blood pressure). [One of these mechanisms should
stem from the blood vessels, and the other at the level of the nervous system]. What are the long-
term consequences of elevated hypertension?

Thunderbolt plc raised finance through the issue of shares on 1 April 2018. The company issued convertible bonds at their nominal value of K20 million. Interest is payable annually in arrears at the rate of 5%. The conversion would be done on the following terms: Each K 4000 bond is convertible at any time up to maturity into 800 ordinary shares. Alternatively the bonds would be redeemed at par after 4 years in 2022. The market rate applicable to non convertible bonds is 9%. (The present value of $1 payable at the end of the year, based on rates of 5% and 9% are given in the table of the Appendix at the end of the question paper.) Required: a) Explain why recognition of convertible bonds should be split into the liability component and the equity component, and calculate the two amounts Thunderbolt recognised. b) Prepare an amortisation schedule showing amounts outstanding at the end of each of the four years to 31 March 2022 (Work to the nearest $000) c) State what amounts would be reported in the statement of profit or loss and other comprehensive income for the year to 31 March 2020 in respect of the bonds, and Page 8 of 8 d) State what amounts would be reported in the statement of financial position as at 31 March 2020 in respect of the bonds.
