You are working in a clinical laboratory, as an entry-level laboratory technician (average salary $35k-$58k/yr). You have purified a novel anti-viral (a cyclic peptide!) with a molecular weight of 2 kDa using ammonia sulfate precipitation. Describe how you would separate the ammonia sulfate from your novel anti-viral using dialysis. It may be helpful to draw a flowchart

The CSI Corporation is looking to replace an existing printing press with one of two newer models that are more efficient. The current press is three years old, cost 32,000 and is being depreciated under MACRS using a 5-year recovery period. The first alternative under consideration, Printing Press A, cost $40,000 to purchase and $8,000 to install. It has a 5 year usable life and will be depreciated under MACRS using a 5-year recovery period. The second alternative, press B cost $54,000 to purchase and $6,000 to install. It also has a 5 year usable life and will be depreciated under MACRS using a 5 year recovery period. The purchase of press A would result in a $4,000 increase in net working capital, and the purchase of Press B would increase net working capital by $6,000. The projected Earnings before depreciation interest and taxes for each alternative is presented below.

The existing press can currently be sold for $18,000 before taxes. At the end of the 5 years the existing press can be sold for $1,000 before taxes. Press A can be sold to net $12,000 before taxes and press B can be sold to net $20,000 before taxes at the end of the 5 year period. The firm is subject to a 40% tax rate.

The company has $100M of debt outstanding with a yield-to-maturity of 8%, and has $150M of equity outstanding with a beta of 0.9. The expected market return is 13% and the risk-free rate is 5%.

Which press is the best option? And why?

Create classes: Person, Student, Employee, Professor, Staff and Address

1. ☐ Address class must have suitable auto-implemented properties for Address 1, Address 2 and City.
2. ☐ Person class must have suitable auto-implemented properties for Name, Residence (type Address) and email.
3. ☐ Student and Employee must be subclasses of Person.
4. ☐ Employee must be a super class for Professor and Staff.
5. ☐ Employee class must have suitable auto-implemented properties for salary (between 2000 to 8000), and hire date.
6. ☐ Professor class must have suitable auto-implemented properties for office hours and rank (use enum, e.g. Assist. Prof., Assoc. Prof., etc.)
7. ☐ Staff class must have auto-implemented property for a designation (use enum, e.g. Office Assistance, Clerk, etc.)
8. ☐ All classes must have suitable constructor(s) and making use of super class constructors as applicable.
9. ☐ Override the ToString method in each class to return the class name and all other information in one/single line (use string interpolation and use base class ToString as applicable)

In the Main Method, create three Lists for (Student, Staff, and Professor) with hard-coded data for at least 4 entries each.

Implement the menu driven CONSOLE logic taking a user input as:

Press 1 to modify Student

Press 2 to modify Staff

Press 3 to modify Professor

Press 0 to exit program

☐ Console application must have a hierarchy of above-shown menus and run continuously until the person quits the application

☐ To list, add, update and delete to a list one must use LINQ.

The general manager of Design Impression Company has proposed the purchase of one of two large six-colour presses designed for long, high-quality runs. The purchase of a new press would enable the firm to reduce its cost of labour and therefore the price to the clients, putting the firm in a more competitive position. The key financial characteristics of the existing press and the two prosed presses are summarised below. Old press: Originally purchased three years ago at an installed cost of $400,000, it is being depreciated using a straight-line method over a 10-year effective life. The old press has a remaining economic life of five years. It can be sold today to net $460,000 before taxes. If the old press is retained, it can be sold to net $150,000 before taxes at the end of five years. Press A: This highly automated press can be purchased for $830,000 plus $40,000 in installation costs. It will be depreciated using the straight-line method over a five-year effective life. At the end of the five years, the machine could be sold to net $400,000 before taxes. Press B: This press is not as sophisticated as press A. It costs $640,000 plus $20,000 in installation costs. It will be depreciated using the straight-line method over a five-year effective life. At the end of five years, it can be sold to net $330,000 before taxes. The firm estimates that its earnings before depreciation and taxes with the old press and with press A or press B for each of the five years will be as show in the table. Assume the firm is subject to a 30% tax rate on ordinary income and NZ tax rule applies on capital gain (capital gain is not taxed). The firm’s cost of capital applicable to the proposed replacement is 14%. Profit before depreciation and taxes for Design Impression Company’s presses Year Old press Press A Press B 1 $120,000 $250,000 $210,000 2 120,000 270,000 210,000 3 120,000 300,000 210,000 4 120,000 330,000 210,000 5 120,000 370,000 210,000 Recommend which, if either, of the presses the firm should acquire.
