Create one detail use-case description for the dentist office system , but do not bother to identify the flow of events within each use case. Whenever new patients are seen for the first time, they complete a patient information form that asks their name, address, phone number and brief medical history, which are stored in the patient information file. When a patient calls to schedule a new appointment or change an existing appointment, the receptionist checks the appointment file for an available time. Once a good time is found for the patient, the appointment is scheduled. If the patient is a new patient, an incomplete entry is made in the patient file; the full information will be collected when they arrive for their appointment. Because appointments are often made so far in advance, the receptionist usually mails a reminder postcard to each patient two weeks before their appointment.

Business faculty at a prestigious community college wanted to evaluate the infuence of Netflix on student academic performance. After careful consideration, the faculty decided to conduct a prelimary study to see if they could justify a more detailed analysis. The preliminary study follows:

Sixty (60) students were selected for two sections of a Business Adminstration class. The students were selected based on their previous performance in an introductory level course. In order to enroll in one of the sections, students had to earn an 85 or higher in the introductory course.

The students in Section 1 agreed to spend at least 15 hours per week preparing for class. During the 15 hours, the students were required to work either in the library or a comparable, on-campus study location that was completely free of distractions (i.e., no smartphones, musical devices, or any other digital media).

The students in Section 2 were given free, unlimited access to Netflix and encouraged to use their account as much as possible when not preparing for class. The students were not required to spend any time preparing for class.

Both sections were taught by the same professor using the same materials. Great care was taken to insure that both classes received approximately the same course content at the same time.

This problem will relate some of the ideas of microstates, ensemble, statisticalmechanical entropy, and our ideal model of many identical oscillators, to intuitive notions of entropy and disorder in a very complex system – a protein. A protein is basically a long chain of amino acid residues that folds into a regular shape and performs a huge variety of biological functions. Biochemistry and biology students will already know a lot about proteins, you may know a lot after having taken organic chemistry. If you don’t know anything about them, it’s a good idea to learn some. The protein in its folded state is called the “native” state. There are beautiful pictures of folded proteins that are easily accessible. Google [ protein folded unfolded ] then go to “images” and you will find many pictures, e.g. the top row on the left and right are good. Intuitively, one says the properly folded structure is “ordered” and therefore low entropy, the unfolded structure is “disordered” and therefore high entropy. In terms of statistical mechanics, if we think in the microcanonical ensemble (ignore any heat bath), there should be an ensemble W_f for the folded condition and W_u for the unfolded condition. Then S_f = lnW_f and S_u = lnW_u. What does this have to do with order anddisorder?

Think in terms of an oscillator model and its degeneracies. The protein with N atoms in either its folded or unfolded state has 3N vibrational modes i.e. consists of 3N oscillators. The oscillators do not have identical frequencies by any stretch of the imagination. But think of each state as having some “average frequency” ωf or ωu, and then imagine the 3N oscillators to all be identical. Each state, folded or unfolded has the same energy E in the microcanonical ensemble.

Now, try to argue, qualitatively but as persuasively as possible why the “ordered” protein has a much smaller ensemble Wf than the unfolded protein with ensemble Wu, and therefore a lower entropy.

(Hint: the folded protein sort of “snaps together” with non-covalent bonds. Think about

what this does to the average frequency. (Hint: see the frequency equation for an oscillator

in the lecture notes. Think about the bonding in the folded protein in connection with the

oscillator force constant in the frequency expression. Think about what this means for the

number of quanta. Think about what this means when you plug into the combinatorial

formula for the number of microstates in the oscillator model

An article in the Archives of Internal Medicine reported that in a sample of 244 men, 73 had elevated total cholesterol levels (more than 200 milligrams per deciliter). In a sample of 232 women, 44 had elevated cholesterol levels. use the a=0.05

a) Write the hypotheses for the test.

b) Calculate the difference in sample proportions between groups.

c) Using 2PropZTest, calculate a P-value.

d) Fill in the blanks to explain what the P-value means: If there is __________________________ between the proportions of high cholesterol, then there is a ___ % chance that there is a _______ or ______________ percentage point difference between the high cholesterol rates.

e) What is your decision about the null hypothesis? Why?

f) Statistically, is there a significant difference between high cholesterol rates of men and women? Support your answer.

g) Calculate a 95% confidence interval for the difference in high cholesterol rates. Does the confidence interval strengthen or weaken your conclusions in parts e) and f)? Why?

When researches incubate whole red blood cells with lactoperoxidase, hydrogen peroxide and radioactive iodine I 125 and then separate the proteins in SDS gel, several radioactive lines are obtained cause iodine binds to prominent tyrosine and histidine residues outside the cell membrane.
When researches incubate whole red blood cells with galactose oxidase and reduce them with sodium borohydride that contains tritium (H-BH43) several radioactive lines are obtained which are just some of the proteins that have been marked with radioactive iodine , thus galactose residues stand out of the cell.
a) Explain the difference in the number of proteins obtained in the two experiments above
b) Why the results of the second experiment do not reflect mark of all the sugars in the membrane?
c) What results will be obtained if we conduct an experiment identical to that described in the question but with inverse vesicles (these are closed vesicles containing all membrane components but where the outer leaf of the membrane turns inward and inward leaf outward)? Thank you!

1- As a medical assistant, explain how to use feedback techniques to obtain patient information including:

a. reflection      b. restatement                          c. clarification

2- Please summarize the flowing paragraphs with your own words:

Scenario 1: Bleeding Control: Arterial Bleeding

Arterial bleeding is characterized by brighter red blood that may pulsate or spurt. Apply direct pressure with a dressing. If blood leaks through, apply more dressing on top. Never remove a dressing. If there are no bone fractures or spinal cord injuries, elevate the wound above the heart. Once bleeding is under control, use roller gauze to secure the dressing, beginning at the distal end and working towards the heart. You can twist the gauze to apply more pressure. Check to make sure blood is not leaking through, and that the bandage is not having a tourniquet effect. Elevate the wound, and call EMS or take the patient to the nearest hospital.

Scenario 2: Bleeding Control: Venous Bleeding

Venous bleeding is more severe than capillary bleeding, but is not under pressure like arterial bleeding. It is characterized by oozing or running of dark colored blood. You should first apply direct pressure with a bandage for 1-2 minutes. Do not lift the bandage to check for clotting. Instead, lift your hand to see if blood is seeping through the bandage. You may have the patient hold the dressing in place while you use roller gauze, beginning at the distal end, to secure the bandage. If bleeding does not continue through the bandage, take the patient to a medical center for wound irrigation and possible stitches.
