Mechanisms of Infectious Disease
32 years old Jason is a general laborer who fell ill shortly after working on a job digging water pipes for the town he lived in. 
The task involved working around stagnant water . Ten days afetr the contract ended , Jason developed a fever and aching muscles . He also had nausea and vomitting and diarrhea. Jason’s friend took him to to physician who listened carefully to Jason’s history . She told him she suspected West Nile fever and ordered serological testing . Jason went home recover and was feeling better by the end of the week.
Answer the following questions in detail and cite all references:
1.Jason’s physician ordered serological tests. How would antibody titers assist the doctors in confirming his diagnosis?
2. When Jason was feeling at his worst he had extereme malaise, vomitting and diarrhea. What stage of illness was he experiencing at that time? What are the physiological mechanisms that give rise to the signs and symptoms of infectious illness.

1. Color Centers
Color center are responsible for beautiful colors of some ancient artwork. Such color centers are observed in many other materials as well, table salt for example. The figure below shows an absorption coefficient, α, of table salt, also known as NaCl. The absorption feature related to the color centers is strongly peaked in the visible and gives rise to the slightly yellow color of table salt. If you would take a salt crystal and irradiate it with energetic ions or X-rays, you would find that the crystal turns dark yellow. Color centers are formed by the creation of socalled Frenkel defects, an ion displaced from its usual site in the crystal. The vacancies that remain after the ions are displaced (by e.g. an energetic particle) can trap charges. Some configurations in which charge can be trapped are shown and named in Figure 2.
2. Metallic nanoparticles
Some of the beautiful colors of 17 th century church windows and ancient glass objects derive their color from the presence of nanometer size noble metal particles. We would like to study the optical properties of a piece of SiO 2 glass with a refractive index of n SiO2 = 1.5 that has a low concentration of Ag nanoparticles (radius R) embedded in it. We illuminate the glass on one side with a white light source and notice a beautiful yellow color in transmission.

Are we alone in the vast universe? This a very polemic question. Most of Scientist (Astronomers, Physicists, Biologists, etc.) state that no civilization has visited our planet. Nevertheless Prof. Abraham Loeb* has written a book describing the visit of an interstellar object called “Oumuamua” that passed 15,040,000 miles from Earth; it is opinion of Prof. Loeb that the object is a piece of advanced technology created by a distant alien civilization.
Prof. Loeb based his hypothesis on the facts that Oumuamua was moving to fast along a strange orbit, it left no trail of gas, and the shape of the object was unusual.
Long time before of the discover of Oumuamua, the astronomer Frank Drake** formulated an equation to estimate the number of civilizations in our galaxy that we might be able to communicate with.
* Abraham Loeb is Israeli American theoretical physicist who works on astrophysics and cosmology.
** Frank Drake is an American astronomer and astrophysicist.
Based on the ideas shared before:
Is there any factual evidence that the Earth have been visited by other civilizations?
Do you think is important to explore the Universe looking for signals from other civilizations?
Make a quick research about SETI institute. Do you consider its mission is important nowadays?

By burning fossil fuels we generate most of the energy needed to sustain our modern life style. Scientists, in the other hand, consider that the use of fossil fuels for more than 100 years is responsible of the global warming. There are some key questions that we must answer:
1.           How are fossil fuels contributing with global warming?
2.           Are fossil fuels renewable? Explain your answer.
3.           Which are the main alternatives to generate energy, that could let us replace the fossil fuels?

Instructions
Using any slide share or movie making software, you can utilize information gathered throughout the course to create a visual travel log. This multi-media presentation will include images, video, and voice over dialogue consisting of a mix of research and original content that demonstrates your analysis of course concepts. The movie will be accompanied by a paper that supplies the dialogue for the visuals of your film.
You may use examples of physics principles in use in everyday life that you previously gave as examples in Modules 01-06. These modules include- Physics principles, the scientific methods, classical compare and contrast, electricity, magnetism, and light, Einstein’s laws of physics, and quantum mechanics. You cannot reuse the same wording as used in previous modules. For example, if you had mentioned using glasses for Module 03, you can once again bring up that concept here, but you cannot read from your Module 03 submission paper.
Requirements
Three-minute video in MPEG-4 format.
Original voice over (written) dialogue and accompanying paper.
Images that help “tell your story.”
30 seconds of original video connecting your experience to your topic.
Narrative concept
Imagine you are a writer for Physics Today (or insert whatever physics pop journal you wish), and you are to create a travel vlog for your an overseas trip. In your presentation, your editor wants you to include all relative physics concepts that you encounter in your journey.
For the heart of the presentation, your editor has deemed it essential to address the following core issues and questions:
Identify physics principles in various real-world examples.
Identify the use of the scientific method in a modern physical problem.
Identify the use of classical physics principles in relation to a real life situation.
Identify physics principles in various real-world examples, and connect to your own experience.
Identify physics principles in various real-world examples and modern technology.
Identify a technology that uses quantum mechanics, and connect to your own experience.

Instructions
In a two-page paper, research three examples of technologies that use quantum mechanics. Identify the strong majority of their elements. Be descriptive.  Explain, in your own words, how these applications impact society. If you or someone you know has ever had an MRI scan for a medical diagnosis, you have experienced the result of quantum physics for measuring bodily structures. Finally, provide another specific example from your own life that could be influenced by these applications.

In a two-page paper, identify the physics principles contained within the following scenario. Explain how these principals connect to Einstein’s theory of relativity or in modern applications in physics. If you use a GPS option on your car or a mobile device, you are using Einstein’s theory of relativity. Finally, provide another example from your own experience, then compare and contrast your scenario to the provided example below.
Scenario
Mandy took a trip to Rome, Italy. She gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination of Rome. It had been a long flight from New York to Rome, but as she stretched, and her bones creaked as though she was old, she knew that in fact, she was a tiny bit younger than her compatriots back home, thanks to traveling at hundreds of miles per hour. In fact, time for her was running slowly compared to her friends in New York for two reasons: the speed at which she had traveled and the height of the airplane above the Earth. Neither, though, were noticeable.
