You have been asked to see D. V. in the Neurologic Clinic on referral from his internist, who thinks his patient is having symptoms of multiple sclerosis (MS). He is a 20-year old man who has experienced increasing urinary frequency and urgency over the past 2 months. Because his female partner was treated for a sexually transmitted disease, D. V. also underwent treatment, but the symptoms did not resolve. D. V. has also recently had 2 brief episodes of eye “fuzziness” and associated with diplopia and brightness. He has noticed ascending numbness and weakness of the R arm with inability to hold objects over the past few days. Now he reports rapid progression of weakness in his legs.

1. MS is an inflammatory disorder of the nervous system causing scattered, patchy demyelinization of the CNS. What does myelin do? What is demyelinization?
2. MS is characterized by remissions and exacerbations. What happens to the myelin during each of these phases?
3. Isn’t D. V. too young to get MS? What is the etiology?
4. What assessment data from the case study caused the physician to suspect a possible diagnosis of MS?

Diagnostic tests are often done to rule out other disorders with similar symptoms. A diagnosis will be made when other disorders have been ruled out, when the patient has 2 or more exacerbations, there is slow, steady progression, and/or the patient has 2 or more areas of demyelinization or plaque formation.

1. What are 4 common diagnostic tests you can begin to teach D. V. about?
2. D. V. asks you, “If this turns out to be MS, what is the treatment?”
3. As part of your teaching plan you want D. V. to be aware of situations or factors that are known to cause an exacerbation of symptoms. List four.
4. The National Multiple Sclerosis Society, 733 3^rd Ave., 6^th Floor, New York, NY 10017-3299 (1-800-344-4867) is a great resource for D. V. What are some resources available in the community that D. V. may need referrals to?

D. V. confides in you that he tried to commit suicide at the age of 14 when his parents got a divorce. He tells you that he knows his girlfriend hasn’t been faithful but he is afraid of living alone. He admits that she occasionally hits him, but he’s afraid if he tells her about his M. S. diagnosis she’ll leave him for good. You recall seeing yellowish bruises on his arms when you took his admission blood pressure.

1. What are you going to do with this information?
2. In view of his personal history and current diagnosis, what two critical psychosocial issues are you going to monitor for in his follow-up visits?

D. V. took advantage of his time with the psychiatric nurse specialist, joined a local MS support group, and told his girlfriend to move out. He later married a woman from the support group.

LANGUAGE: JAVA

Create a New Project called YourLastNameDomainName.

Write a DomainName class that encapsulates the concept of a domain name, assuming a domain name has a single attribute: the domain name itself. Include the following:

- Constructor: accepts the domain name as an argument.

- getDomain: an accessor method for the domain name field.

- setDomain: a mutator method for the domain name field.

- prefix: a method returning whether or not the domain name starts with www.

- extension: a method returning the extension of the domain name (i.e. the letters after the last dot, for instance com, gov, or edu; if there is no dot in the domain name, then you should return "unknown")

- name: a method returning the name itself (which will be the characters between www and the extension; for instance, yahoo if the domain is www.yahoo.com- (Links to an external site.)--if there are fewer than two dots in the domain name, then your method should return "unknown").

Write a program that demonstrates the DomainName class by prompting the user for the domain name and displays the output of the last three methods.

NOTE: The DomainName class is a new class within your project. This does not affect the name of your Java Project above.

ALSO, DO NOT FORGET TO INCLUDE THE FOLLOWING AS A COMMENT SECTION AT THE TOP OF YOUR PROGRAM:

1. Student Name

• Experiment is do slugs prefer plant based foods or animal protein?

• Think about an experiment you could run to test your hypothesis. What would be the variable(s) in your particular experiment? For each variable that you identify, say whether it would be considered an independent- or dependent variable. Also, say whether it would be considered a quantitative- or qualitative variable. Explain your reasoning for assigning each variable as quantitative or qualitative. Hint: See pp. 2-3 for help on identifying variables.

• Come up with at least three extraneous variables that you would have to control for (i.e. variables that you are not testing for, but could possibly affect the results/interpretation of your experiment). For example, if you hypothesized that slugs are more likely to feed on greasy foods, then think of over variables, besides the food’s greasiness, that might influence your results.

• Come up with a step-by-step (and detailed) procedure for an experiment you could run to test your hypothesis (attach additional sheets if necessary). Make sure you can perform this experiment using only the materials available to you (since this is being made up, you can have whatever materials you want). As part of your procedure, describe how you would control for the variables you listed in question #7. Also describe how you will quantify food consumption by the slugs.

Here are some things to consider when coming up with your procedure:

•Your slug(s) will feed inside the provided plastic container until the next lab meeting.

• Come up with a way on how you can quantify the amount of feeding that takes place. In other words, see if you can come up with a way of making the amount of feeding a quantitative variable.

•Make sure to put enough water to just cover the bottom of your container. Slugs can live only in moist environments.

•Make sure to wear gloves when handling slugs. Then, take off the gloves before you handle anything else. This will prevent slug slime from getting on everything.

Animation—The Millikan Oil Drop Experiment
Watch the animation to study the Millikan oil drop experiment.
Click to launch the animation
The Millikan oil drop experiment was a direct and convincing experiment for the measurement of the charge on a single electron. Millikan performed an experiment on a charged oil droplet. By balancing the forces acting on the oil droplet, the charge on a single electron can be calculated. Millikan found that the charge of an oil droplet is always a whole-number multiple of −1.60×10−19 C. Thus, the charge on a single electron is −1.60×10−19 C.
Various types of forces that are observed in nature
You can observe the following types of forces in nature:
The attraction or repulsion between objects or particles that have electrical charge is known as the electric force.
The force with which the Earth, the Moon, or any other massively large object attracts another object toward itself is known as the gravitational force.
The force exerted upon an object that is in contact with another stationary object is known as a normal force.
The special type of frictional force that acts upon objects as they travel through the air is known as an air resistive force.
The force exerted by a compressed or stretched spring upon any object that is attached to it is known as a spring force.
The upward force caused by the air pressure that keeps things afloat is known as a buoyant force.

Part B - The effect of an electric field (voltage) on a negatively charged oil droplet
In the Millikan oil droplet experiment, the oil is sprayed from an atomizer into a chamber. The droplets are allowed to pass through the hole into the chamber so that their fall can be observed. The top and bottom of the chamber consist of electrically charged plates. The upper plate is positively charged, and the lower plate is negatively charged. X rays are introduced into the chamber so that when they strike the oil droplets, the droplets will acquire one or more negative charges. The electric field (voltage) is applied to the metal plates.
Watch the animation and identify the effects of an electric field on the motion of a negatively charged oil droplet. Consider the gravitational force as Fg and the electric force as Fe. All the other forces acting on the oil droplet can be ignored as their effect on the motion of the oil droplet is negligible.
Check all that apply.
Hints
Check all that apply.
If Fe is increased until it is equal to Fg, the negatively charged oil droplet will remain stationary.
In the absence of an electric field, the oil droplet falls freely due to the gravitational force.
In the presence of an electric field, the negatively charged oil droplet moves freely toward the negatively charged plate.
If Fe is greater than Fg, the negatively charged oil droplet will move freely toward the negatively charged plate.

Part C - The total charge on a negatively charged oil droplet
In Millikan’s experiment, the oil droplets acquire one or more negative charges by combining with the negative charges that are produced from the ionization of air by X rays. By measuring the charges on the oil droplets, he calculated the charge on a single electron as −1.60×10−19 C. The charge on any negatively charged oil droplet is always a whole-number multiple of the fundamental charge of a single electron.
If Millikan was measuring the charge on an oil droplet with 7 negatively charged electrons on it, what charge would he have measured on the droplet?
Express your answer to three significant figures and include the appropriate units.
