Cryonics

The freezing of people , known as cryonics is the technique of keeping frozen corpses for years to resurrect them someday. The idea is fantastic : you die and the doctors put him in a tank of liquid nitrogen, stored at -320 º F , the temperature at which the body does not rot , and in about 500 years , scientists discover a way to fight the disease that caused his death and defrost .

Today , it already gives some embryos : embryos can stay in " refrigerator " with good chances of surviving a thaw - it is estimated that nearly 60 % of them get nowhere , giving rise to a baby . So many people believe that this will still work with human well-developed . 

About 200 people and 20 animals passed by freezing since it was first held in 1962 . In the United States , the cryogenic can only be legally performed in humans after having been pronounced legally dead.

The procedure is done in 4 steps :

1. Once a person dies , a company official cryogenics cools the body with ice. At this stage, the body temperature is somewhat above 32 ° F.

2 . In this phase , the body also receives an injection of substances anticoagulants to keep the blood vessels clear . Then, all the blood is pumped out of place and come chemicals which protect the cells from freezing time , avoiding the formation of ice crystals that disrupt the cellular structure

3 . At the site where the body will be frozen, the body undergoes a gradual cooling in an ice chamber cleaning. To avoid damage to cells, it is intended that all tissues from freezing at the same rate .


4 . After cooling , the body is slowly submerged in a tank of liquid nitrogen until completely covered . When this phase is over, after one week, the body is frozen  -320 ° F prevented from rot. The body is in the tank for eternity or until someone invents a technology to resuscitate him.

So this is a good technique that scientific advancement has given us , I think particularly a good idea , but is a hard work and high costs . But maybe one day we can make use of this technique perfectly in the future.

Project 2013 - Composition

There once was a couple who lived in the city of Rio de Janeiro in the 19th century. Conrad and Mariana had been married for eight years, and always had a great relationship.

Mariana was a pretty girl: she was blonde, had bright eyes and the delicacy of a ballerina.  Conrad was a tall, bearded man. He was successful. He looked rough and always wore a hat that never took off. Mariana had always served as a great wife to Conrad, and he always treated well her.

One day the two of them were having dinner at their mansion and Mariana decided to make a comment about Conrad. She said that Conrad’s hat was inappropriate for a successful man. Conrad got offended because Mariana had never complained about anything, and he loved that hat, and the twoargued offensively. Conrad, very nervous, withdrew from the table.

Mariana sadly decided to live with her friend, who took her to know the dark side of society, where betrayals and lies were normal. Her friend tried to influence her, criticizing her husband and introducing her to other men. Mariana got angry because she was not used to it, then she went back home, and her husband was there, holding a bouquet of flowers and a new hat for her.
