Lower Heart Rate At 34 Weeks

Is it important to take care of influenza A H1N1?

Yes because this has already been infected and there have been many thousands of deaths worldwide. We must not take lightly the pandemic that emerged in Mexico and is now worldwide.

We give some precautions to avoid contracting the flu:
  • Avoid close contact with other people: Avoid close contact with sick people. If you get sick, stay away from others to protect them from getting sick too.


  • Stay home when sick: If possible, stay home from work, school or public places if sick. In this way, will help prevent others from catching your illness.


  • Clean your hands: Wash your hands with soap and warm water between 10 and 20 seconds on a frequent basis. Also wash between fingers, and finally the pulse or wrist. Alternatively, you can use alcohol gel or liquid disinfectant.

  • Avoid touching your eyes, nose or mouth often spreads germs when a person touches something contaminated with germs and then touches the eyes, nose or mouth.
  • other good health habits: Get plenty of sleep, be physically active, manage stress, drink plenty of fluids and eat nutritious food.
  • Ventilate the haunts: Always do this so that if the virus enters a place out.

  • Cover your mouth and nose when sneezing or coughing: Do it with a tissue or, if he had, with the fold elbow. Never use the palm of the hand.

  • Use masks or masks, recommended only in a public setting or in proximity to infected, remembering that have a certain airtime.


If you have high fever (38 and 40 ยบ), recurrent dry cough, sore throat, runny nose, body aches, headache, chills, fatigue, pain eyes, loss of appetite, breathing problems such as shortness of breath, vomiting or diarrhea, ask your doctor for treatment disease, never take medicines on their own.

It proposes a way to teleport beams

Usually, when talking about quantum teleportation, he is referring to the transfer of quantum states of a particle to another without a physical link. Now, physicists have investigated a slightly different form of teleport, which teleports a quantum field, or a full beam from one place to another. It takes such teleportation "strong" for some applications of quantum information, and could lead to quantum teleportation of images.


a plan is proposed to teleport a beam of light, including fluctuations in time. They hope to demonstrate that it is possible that a physical object in one place may arise elsewhere in the same quantum state, so any type of measurement would produce the same result in both places.


In its proposal, the scientists investigated a uniformly spaced stream of photons, or ungrouped. If single photons are detected in a flow that are spaced similarly to the photon flux at the entrance, that would verify the complete quantum teleportation field. The scientists wanted to find the conditions under which this detection could occur. They found that light-compression technique used to improve the accuracy of measurements, could enable quantum teleportation of a quantum flux of photons, if the compression is performed in a wide bandwidth.


Scientists note that the compression levels are challenging, but new research in the design of experiments could reveal more optimal methods. One of the biggest challenges for the realization of this proposal is the requirement for flexible sources of squeezed light quality. If physicists can overcome these challenges, the ability to carry light beams could lead to many interesting applications. For example, researchers suggest that utilza could be a multi-channel version, in which two parallel teleport or more beams, to teleport quantum images.

What is more important, it is likely that the teleportation of light beams offer undiscovered potential and this will bring a breakthrough for science

Do electrons are "indivisible"?

If your answer to this question is yes, maybe you are wrong since the latest advances in physics reveal that the "indivisible" electron may not be as "indivisible" in all cases. It has been discovered that electrons accommodated in quantum-scale wires can be separated into two smaller particles called spinons and holons.

The separation effect occurs when electrons in which too many competing for limited space. Since electrons repel each other, if they are placed in a very narrow wire, found it increasingly difficult to overtake one another. Apparently the electrons respond by breaking his magnetism and loaded into two separate particles, the "spinons" (spinons) and "holons" (holons).

The experiment that was used to test this hypothesis on the separation of electrons is very interesting. Was located to the electrons in a very thin thread, take it to absolute zero temperatures and then see how the electrons jumping between that wire and a nearby metal.

When the metal and wire were close, the electrons could jump to the metal via quantum tunneling . In this way scientists could take action under a variety of magnetic fields to find out what happened when the electron jumped . These measurements indicated that the electrons eventually jumping had to be divided into two new particles.

In conclusion, if the electrons can be divided if they are competing for limited space.
This would give the fact that science teachers should change the idea that electrons are "indivisible."

Did you know that there is a particle accelerator called the God Machine?

It's true, is the most powerful which could make great discoveries, such as confirming the existence of invisible matter or extra spatial dimensions, once it becomes operational in September this year. "Being of God", as he has called the Large Hadron Collider (LHC), is also purpose is to uncover the mysteries of the origin of the universe.

If you're wondering what is a particle accelerator? They are machines that accelerate charged particles (ions) using electromagnetic fields in a hollow tube which has a vacuum, and finally each ion collide with a stationary target or another particle in motion. The scientists analyzed the results of collisions and try to determine the interactions that govern the subatomic world.

According to Einstein's formula E = mc ² mass is a form of energy. This means that energy can be transformed into mass and vice versa. In particle accelerators that is used to transform kinetic energy into mass in a particle collision. Thus, new particles can be created in particle collisions at high relative velocities. In the search for new heavy particles is important to be able to accelerate particles to high energies. The higher energy of the original particles, heavy particles can be created in particle collisions.

For reasons of repairs among other things, the God machine will be activated between September and November this year
