A 38-mm thick HMA surface course is to be designed to carry 15,000,000 ESALs during the life of the pavement. A 9.5-mm nominal size aggregate is required. The aggregates shown in Table 4-14 are available for use. The control limits and restricted zone boundary are shown in Table 4-10. Based on environmental information, a PG 64-22 is used as the binder. Design a HMA mix according to the Superpave method.

(a) State any five issues dealt with in the regulatory framework of accounting.

(b) Outline any four benefits multinational companies may derive from global harmonization of accounting standards.

(c) In preparing financial statements, accountants follow certain fundamental assumptions and policies. List and explain two of these policies and assumptions under the following:
(i) boundary rules
(ii) measurement rules
(iii) ethical rules

1. What are point defects? Please explain the relationship between point defects and materials strength and ductility. (10 pts) 2. What are dislocations? Please explain the relationship between dislocation and materials strength and ductility (10 pts) 3. What are grain and grain boundary? Please explain the relationship between grain size/grain boundary and materials strength and ductility. (10 pts) 4. What is the solid solution and what factors affect solubility? (5 pts) 5. What is the stacking fault? (5 pts) 6. What is a unit dislocation? What is a partial dislocation? What is an extended dislocation? (10 pts) 7. The actual strength of a metallic material is tens of times smaller than its theoretical strength because of dislocation. However, the strength of the same material can be significantly increased through dislocation strengthening. Why does dislocation appear to behave in an opposite way? (10 pts) 8. Please use the characteristics of chemical bonding, crystal structures and dislocations to explain why metallic materials are strong and ductile and why ionic and covalent materials are strong but brittle? (20 pts)

Church organs have a set of pipes with different lengths. With those different pipes organs can produce sounds over a wide range of frequencies. If the lowest frequency produced by an organ is 31.6 Hz, and the highest frequency is 1.80 kHz, then what is the shortest possible wavelength of sound the organ can produce? Assume that the speed of sound is 336 m/s.
B) What is the longest possible sound wavelength the organ can produce?

A boundary survey is being conducted for a client’s parcel of land. You find and accept a concrete monument for a boundary corner and determine its position to have X and Y coordinates of 3496.45 ft & 9798.03 feet, respectively (Corner A). You also find & accept an iron rod as a corner and determine its position to have X and Y coordinates of 5272.92 ft & 10161.36 feet, respectively (Corner C). You determine that you should replace a lost corner (Corner B) between these accepted monuments using record distances provided on a 1995 survey map. The record distance from Corner A to B is 1405.91’. The record distance from Corner C to B is 1121.30’. What are the coordinates the field crew should use to reset corner B? HINT: You will get 2 solutions using distance-distance intersection techniques. Calculate both solutions but chose the solution that is northeasterly from Corner A & northwesterly from Corner C as your final solution. Also, use Civil 3D to check your answer. Show screenshot of your steps. Hint: by plotting the given coordinates and then using circles with radii, we can determine the intersection points.

In 2002 New York Times report indicated that Brazil's Amazon-based export industries that are leading to the destruction of environment introduced new environment-oriented foreign aid. Why was Brazil considered, what was the procedures followed, and explain it actual effect?

A $16,000 bond redeemable at par on July 27, 2012 is purchased on October 19, 2002. Interest is 6.9% payable semi-annually and the yield is 7.3% compounded semi-annually.

a. What is the cash price?

b. What is the accrued interest?

c. What is the quoted price?

LIS Corporation, an environmental service provider, had revenues of $209 million in 2002 and reported losses of $3.1 million. It had earnings before interest and taxes of $12.5 million in 2002, and had debt outstanding of $109 million (in market value terms). There are 15.9 million shares outstanding, trading at $11 per share. The pre-tax interest rate on debt owed by the firm is 8.5%, and the stock has a beta of 1.15. The firm's EBIT is expected to increase 10% a year from 2003 to 2006, after which the growth rate is expected to drop to 4% in the long term. Capital expenditures will be offset by depreciation, and working capital needs are negligible. (The corporate tax rate is 40%, and the treasury bond rate is 7%.)

1. Estimate the cost of capital for LIS.

2. Estimate the value of the firm.

3. Estimate the value of equity (both total and on a per share basis).

y = quit rate per 100 employees in manufacturing

x = unemployment rate

The data are for United States and cover the period 1990-2002.

(a) Estimate the regression and report the results

(b) Construct a 95% confidence interval for β.

(c) Test the hypothesis H₀ : β = 0 against the alternative β=0 at the 5% significance level.

(d) Test Normality of the residuals using Jarque-Bera test.

(e) What is likely to be wrong with the assumptions of the classical normal linear model in this case? Discuss.
