CASE STUDY #1

Review the case below and answer the following questions.

This should be original work, no references or information from online. Please be detailed.

38-year-old female with excessive thirst, frequent urination, and weight loss.

History: Cindy Mallon, an 38 year old Caucasian female in previously good health, she has noticed that in the past month, she is increasingly thirsty. She gets up several times a night to urinate, and finds herself gulping down glassfuls of water. At the dinner table, she seems unusually hungry, yet she has lost 5 pounds in the past month. In the past three days, she has felt lethargic and had noted some visual changes where her vision is blurry.

QUESTIONS:

At the doctor's office, blood and urine samples are taken. The following lab results are noted:

blood glucose level = 445 mg/dl (normal = 50 - 170 mg/dl)

blood pH level = 7.40 (normal = 7.35 -7.45)

urine = tested positive for glucose and negative for acetone / acetoacetate (i.e. ketone bodies)

Answer the following questions, be sure to use proper terminology and detail your answers considering your review of your chapter via textbook, notes and video screen cast of module components:

1. What would be some endocrinological reasons for her blood-glucose levels to be elevated?

2. At the office, you examine her and notice that she has a dark pigmented ring around her neck and is considered to be morbidly obese. The pigmentation is called acanthosis nigricans and is sometimes noted with metabolic disorders. Do those signs have to do with her current condition?

3. Explain why Cindy is urinating so frequently in detail and physiologically how and why it occurs.

4. Explain her constant thirst in detail including what causes it.

5. What are the possible long-term complications of her disease?

The grade point averages (GPA) of 18 randomly selected college students are used to estimate the mean GPA of the college students. The GPAs from the sample are as follows:

2.3       3.3       2.6       1.8 0.2 3.1       4.0       0.7 3.1

2.3       2.0       3.1       3.4       1.3       2.6       2.6 3.7 2.2

1. (5 points) Is it justified to use of the standard normal distribution to construct the confidence interval? Explain.
2. (10 points) If the population is assumed to be normally distributed, construct a 98% confidence interval for the population mean GPA. Show your work in detail and use 3 decimal digits.

Please briefly explain the answer and why.

(1) What are the differences between a process and a thread? Explain in perspectives of memory sharing, switching, communication, etc.

(2) In inter-process communication using message passing, there are two types of send/receive operations: blocking send/receive and non-blocking send/receive. What is the difference between the two approaches? Explain how the operations will behave when called.

(3) When a process is created, memory is allocated for the process. Describe each section of the memory allocated to the process, and what goes into each section.

In great detail please answer the following (at least 300 words per each question)

a. Inflation in the country of Hypothetica is currently 5%, below the target range of its central bank. (i) What does this tell you regarding Hypothetica’s likely output gap? Illustrate it using an AS-AD diagram, and briefly explain your diagram In this situation, what is the central bank likely to do with regard to monetary policy? Briefly explain your answer and state also what is likely to occur to the price level and output at the end of this process (there is no need to draw a diagram, but you can if you feel it helps you explain your answer) What happens if the central bank does not intervene? Will the economy eventually return to long-run equilibrium (potential GDP)? Briefly explain your answer and state also what is likely to occur to the price level and output at the end of this process (there is no need to draw a diagram, but you can if you feel it helps you explain your answer).
