Diagnostic Virology Case Study #3

Patient A

A 17 yr old female is brought to the office for evaluation of a sore throat and fever. Her symptoms started about 1 week ago and have been worsening. She has been extremely fatigued and has spent most of the last 3 days in bed. She denies any ill contacts. She has no significant medical history, takes no medications, and has no allergies. On examination of her pharynx shows her tonsils to be markedly enlarged, almost touching in the midline. They are erythematous and covered with white exudates. She has prominent cervical adenopathy, which is mildly tender. A cardiovascular examination is normal, and her abdomen is soft, nontender, without organomegaly. A rapid streptococcal antigen test is negative. Depite the use of amoxicillin to combat streptococcal infection the patient is not getting better and now complains of a red rash (likely an allergic response) from head to toe.

1. What specific viruses may be involved in this infection?

2. What specific tests can be performed to help confirm a diagnosis (think serology and another type of specimen).

3. If you were to culture this patient for a virus what types of cells would you need to use to assure it will grow.

4. How was this viral infection likely acquired?

5. What are the basic characteristics of this virus? (example: DNA or RNA, single or double stranded, enveloped or naked, helical or icosahedral)

What are the five difference between Governments and Businesses? Provide an illustrative examples.

How does GASB distinguish between investors and creditors?

Low-energy lightbulbs typically cost $3.75, have a life of nine years, and use about $1.85 of electricity a year. Conventional lightbulbs are cheaper to buy, for they cost only $.55. On the other hand, they last only about a year and use about $6.85 of energy.   

a. If the real discount rate is 6%, what is the equivalent annual cost of the two products? (Do not round intermediate calculations. Enter your answers as a positive value rounded to 2 decimal places.)

b. Which product is cheaper to use?

1. Consider the current COVID-19 pandemic and the subsequent economic recession.

a). Are firms looking to invest or expand in this environment? Using and drawingthe supply curve for bonds, explain what happens.

b). Are individuals looking to invest or buy bonds in this environment? Assume that there are NO other assets in this economy – we are just talking about bonds. Use and draw the demand curve for bonds. Hint: Consider bond as being an asset and use the Theory of Portfolio Choice.

Cost of Common Equity

The future earnings, dividends, and common stock price of Carpetto Technologies Inc. are expected to grow 4% per year. Carpetto's common stock currently sells for $25.50 per share; its last dividend was $2.00; and it will pay a $2.08 dividend at the end of the current year.

Design a "bungee jump" apparatus for adults

. A bungee jumper falls from a high platform with two elastic cords tied to the ankles. The jumper falls freely for a while, with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that you have cords that are 11 m long, and that the cords stretch in the jump an additional 23 m for a jumper whose mass is 140 kg, the heaviest adult you will allow to use your bungee jump (heavier customers would hit the ground).

a). Make a series of simple diagrams, like a comic strip,showing the platform, the jumper, and the two cords at varioustimes in the fall and the rebound. On each diagram, draw and labelvectors representing the forces acting on the jumper, and thejumper's velocity. Make the relative lengths of the vectors reflecttheir relative magnitudes

(b). At what instant is there the greatest tension in thecords? How do you know?

(c). What is the jumper's speed at this instant?

(d). Is the jumper's momentum changing at this instant or not?(That is, is dp/dt non-zero, or zero?) Explain briefly.

(e). Focus on this instant, and use the principles of thischapter to determine the spring's stiffness k(sub-s) for each cord.Explain your analysis. Give numerical values for yourdesign.

(f). What is the maximum tension that each cord must supportwithout breaking?

Give numerical values for your design.

(g). What is the maximum acceleration ("g's") that the jumperexperiences?

What is the direction of this maximum acceleration?

(h). State clearly what approximations and estimations youhave made in your design.

Physical Properties of Hydrocarbons

Solubility: Indicate if the substance is soluble or insoluble in water and ligroin. Does this indicate that the substance is polar or non-polar?

Density: Is the substance more dense than water (sinks) or less dense than water (floats). For ligroin, can you tell anything about relative density?

A heat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 250°C enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. Chlorine gas enters the exchanger at 1 bar and 33.0°C and leaves the exchanger at 132.0°C. Assume the heat exchanger is adiabatic.

A)What is the specific enthalpy of the inlet steam stream? (Use liquid water at 0.01°C as a reference state.)

B)What is the specific enthalpy of the outlet steam stream? (Use the same reference state.)

C) What is the specific enthalpy of the inlet chlorine gas stream? (Use chlorine gas at 1 bar and 33.0°C as a reference state.)

D) What is the specific enthalpy of the outlet chlorine gas stream? (Use chlorine gas at 1 bar and 33.0°C as a reference state.)

E)How many moles of chlorine gas enter the heat exchanger?

F)What is the ratio of the volume of inlet steam to the volume of inlet chlorine gas? Use the ideal gas law to calculate the volume of chlorine entering the process.

G)How much heat is transferred from the steam stream per cubic meter of chlorine gas?
