What happened?

The air pollution claimed seven million lives around the world in 2012, according to figures released Tuesday by the World Health Organization. 

When? Where?

 In 2012 around the world,  but more in China, India and Japan

Who was involved?

All people

Why did happen?

It is caused by burning of noxious fuels like coal, wood and animal waste

My opinion 

In my opinion, we should do something to solve this problem that affects us and will affect us much more in the near future, we should be committed to caring for the environment, and if necessary, create laws to regulate emissions of harmful gases, otherwise, the next generation will not have a quality of life as everyone should have.

My opinion on English

In my view, essential to learn English for the workplace because it allows to have more chances of being accepted into jobs, in addition, it is important in everyday life, because much of what we use is written in English, such as computers, manuals , games console, etc.. Also, knowing English is an excellent tool for communicating with foreigners and also learn more about different cultures, or when going on a trip abroad, learn English greatly facilitates to be there

My future plans

Next year i will take six of engineering. Still not decided what career i will continue but I have thought systems engineer. To be a systems engineer i have to go to engineering school in Montevideo, and to receive the title will need five years or 450 regular classes. I have also planned to do a course in English to better handle the language and perform more in my work

What Does a Systems Engineer Do?


A systems engineer is the person responsible for developing a system, such as a computer system, for a client. He discusses the client's needs, plans a system, creates the system, and troubleshoots it for any bugs. The system engineering field is broad and ranges from computer system engineering to power system engineering. Regardless of the person's specialty and the project, the main goal of a systems engineer is to create the most efficient engineering project that can handle a client's needs both at the time of creation and in the future as those needs change. Often the systems engineer works on a complex project, such as robotic machinery or computer chips.

My favorite movie

Movie Limitless

I have several movies that I like and I find it hard to choose just one but I think the movie Limitless is one that most caught my attention. because it deals with the brain and its capabilities, which I find very interesting even though only is science fiction.
It was directed by Neil Burger and producer by Leslie Dixon, Ryan Kavanaugh and Scott Kroopf. It was released in March 8, 2011. It is 105 minutes long. It was starred by Bradley Cooper, Abbie Cornish and Robert De Niro. Its genre is mystery, science fiction and thriller

Trailer:

In this link we can see the Trailer of the movie: http://www.youtube.com/watch?v=THE_hhk1Gzc

What is the film about?

It is about a paranoia-fueled action thriller about an unpublished writer whose life is transformed by a top-secret smart drug that allows him to use 100% of his brain and become a perfect version of himself. His enhanced abilities soon attract shadowy forces that threaten his new life in this darkly comic and provocative film.

Images of the movie

My personal opinion

In my personal opinion this film is very well produced and has a good dialogue and interesting plot, but loses some suspense how begins and also the end of the movie was unfinished.

X-Ray Machine

Definition

X rays are electromagnetic radiation that differentially penetrates structures within the body and creates images of these structures on photographic film or a fluorescent screen. These images are called diagnostic x rays.

Purpose

Diagnostic x rays are useful in detecting abnormalities within the body. They are a painless, non-invasive way to help diagnose problems such as broken bones, tumors, dental decay, and the presence of foreign bodies.

Description

X rays are a form of radiation similar to light rays, except that they are more energetic than light rays and are invisible to the human eye. They are created when an electric current is passed through a vacuum tube. X rays were accidentally discovered in 1895 by German physicist Wilhem Roentgen (1845-1923), who was later awarded the first Nobel Prize in physics for his discovery. Roentgen was also a photographer and almost immediately realized that the shadows created when x rays passed through the body could be permanently recorded on photographic plates. His first x-ray picture was of his wife's hand. Within a few years, x rays became a valued diagnostic tool of physicians world-wide.

The first radiography

How x rays work

In this link we can see how x-ray machine work: http://www.youtube.com/watch?v=V9Mi8tqGQlo

X rays pass easily through air and soft tissue of the body. When they encounter more dense material, such as a tumor, bone, or a metal fragment, they are stopped. Diagnostic x rays are performed by positioning the part of the body to be examined between a focused beam of x rays and a plate containing film. This process is painless. The greater the density of the material that the x rays pass through, the more rays are absorbed. Thus bone absorbs more x rays than muscle or fat, and tumors may absorb more x rays than surrounding tissue. The x rays that pass through the body strike the photographic plate and interact with silver molecules on the surface of the film.

Once the film plates have been processed, dense material such as bone shows up as white, while softer tissue shows up as shades of gray, and airspaces look black. A radiologist, who is a physician trained to interpret diagnostic x rays, examines the pictures and reports to the doctor who ordered the tests. Plain film x rays normally take only a few minutes to perform and can be done in a hospital, radiological center, clinic, doctor's or dentist's office, or at bedside with a portable x-ray machine.

Precautions

Although unnecessary exposure to radiation should be avoided, the low levels of radiation one is exposed to during an x ray does not cause harm with a few exceptions. Pregnant women should not have x rays unless in emergencies the benefits highly outweigh the risks. Exposure of the fetus to x rays, especially during early pregnancy can increase the risk of the child later developing leukemia. Body parts not being x rayed should be shielded with a lead apron, especially the testes, ovaries, and thyroid.

Conclusion:

I think that x-ray machine is one of the most important inventions, because it has contributed much in the field of medicine and technology
