What is prominensa? Prominensa is explosive event accompanied by flame emission. Flames emitted is called protuberans. Thus, it can be said as an explosion prominensa sun accompanied by the emission protuberans. The explosion occurred around the sun spots. Protubelans emitted in all directions. The jet can reach a height of 230 000 km so that it can penetrate into the chromosphere and corona layer. As a result, a lot of gas in the layer of ionized hydrogen into protons and electrons (charged particles). Charged particles are emitted at very high speeds. Some of them get into Earth's atmosphere.

Before entering the Earth's atmosphere, the charged particles are deflected towards the north pole and the south pole by the Earth's magnetic field. Furthermore, the particles are reflected repeatedly between the two poles. Along with repeated reflection, the particles velocity is decreasing. After reaching a certain speed, the particles enter the Earth's atmosphere. This causes part of the atmosphere where the particles fall incandescent and emits a very bright light. That light called aurora. Because it occurs in the polar aurora is often called the northern lights.

Another consequence is the disruption of the prominensa radio and television broadcasts. Waves emitted or received a television and radio is radio waves. To get to a radio or television radio waves undergo a process of reflection. Reflection of radio waves by a layer of the atmosphere, the ionosphere. The ionosphere is the layer of the atmosphere that contains ions and free electrons. This layer will be disrupted if there are charged particles pass through the other. That's why broadcast radio or television will be disrupted if the charged particles from the sun prominensa results fall into the Earth's atmosphere.

Clumps of sun (granule) arising from a very large temperature difference between the core and the photosphere. The temperature at the Sun's core reaches 15 million K, while at 5700 K photosphere Very large temperature differences this causes a very hot gas flow from the core of the sun to the photosphere form clumps. Clumps is called lumps or granules sun. The existence of granular photosphere causing uneven surface. Consequently, in the photosphere formed dark areas called sun spots. Granular state change from time to time. Sometimes the granules look like wicker. Seen with a telescope, granules look like grains of rice that glow. Distance antarbutir also changing. The distance between the two points to reach 2000 km.

Sun spots (sunspots) is the dark area on the photosphere. Dark area is caused by the temperature in the area is lower than the surrounding area. The temperature difference is caused by obstruction of the clouds (clumps) of hot gas from the inside of the sun (the sun's core). This is due to the sun's magnetic field interference. Diameter of sun spots is estimated at 80,000 km. Diameter is much larger than the diameter of the earth. The diameter of the earth about 12,736 miles. Sightings (age) spots the sun is different, there is the age of a few minutes, but there are a few days old. The amount also varies from time to time.

One type of power plant is a power generator. Electric generator is a device producing electricity by converting mechanical energy into electrical energy. Electric generators exerts a force on the free electrons that electric current can flow to the outer circuit. To be able to generate electricity, power generators require external sources of mechanical energy that can be converted into electricity. A common source of mechanical energy used today comes from steam turbine engines, turbines of power (hydropower), or it could be from wind power turbines. Generally at this time, our electricity is the result of the electric generator.

Why mass aircraft tons can float in the air? Bernoulli's principle can provide an answer to this question. Bernoulli's principle is a principle of physics associated with the fluid, especially a moving fluid. Bernoulli's principle widely used in many technological applications, such as the principle of the aircraft. Mathematically, Bernoulli's principle is expressed by the equation:

RV2 ½ p + r + g y = constant (fixed)

p = pressure of the fluid, r = density of fluid, v = rate of fluid, y = height increased fluid, and g = acceleration due to gravity.

If the fluid flow is not raised then the value of y = 0 at each point, so the above equation becomes much simpler, namely:

RV2 ½ p + = constant (fixed)

This equation states that if the fluid flow rate increases, the pressure of the fluid in that place becomes smaller, and vice versa. Hence, a winged aircraft can climb to the sky, because the air pressure at the top of the wing is less than the air pressure at the bottom of the wing. Why does this happen?

Picture
The upper part of the wing is made more curved than the bottom wing. It is caused when the aircraft was moved to the front, the air flow rate at the top of the wing will be faster than the rate of air flow at the bottom of the plane, because the travel time (t) of air flow on both the same and the length of the track (s) through the air at the top is longer than the length of the trajectory in the plane (remember v = s / t). As a result of the rate of air at the top of the wing faster than the rate of air at the bottom of the wing, the air pressure at the top is smaller than the air pressure at the bottom of the wing. As a result of the pressure difference is the wing aircraft will be lifted by the upward force (remember, this is not the buoyant force).

Jen-Hsun Huang, Nvidia's Chief Executive Officer, Wednesday, March 20, 2013, Logan said the chip will use Kepler architecture design, which will boost the image quality on mobile phones and tablets.

Cip Logan also uses coded CUDA technology, which is designed for mobile devices. This technology enables the authors to exploit the capabilities of computing applications from components central processing unit and graphics processing units simultaneously.

"Logan has the ability Cip long we want to show to the world," Huang said in a conference session Graphic Processing Unit, which was held two days ago in Santa Barbara, California.

Cip Logan will be mass produced in the next year, though will be launched to the market on a small scale at the end of this year. As a surprise, Huang has not mentioned the name of the device that will use this chip. While chip Parker would follow a year later.

Nvidia has a tradition of using the names of the heroes of the comic for its products, such as Logan, named after the character in X-Men comics, and Parker, the original name of the character Spiderman is Peter Parker.

Samsung officially introduced a new flagship Android smartphone, the Galaxy S4, in New York, USA, on March 14, 2013 local time.

Fitted with a powerful specification, Samsung arming these products with various applications in terms of new features, such as S Translator, Air Gestures, Smart Pause, Smart Scroll, and S Health.

Here are some features of the Galaxy S4 explanation, as quoted by The Verge, Friday (03/15/2013).

Google Now an exclusive application that previously only existed in Android Jelly Bean with similar capabilities in iOS rumored Siri will be available soon on the iPhone & iPad.

This conclusion can be drawn after engadget find promo video on Youtube (video has been withdrawn) that shows the features and capabilities of Google Now on iPhone & iPad. The video has a voice narration with video promo which it demoed earlier android application integration with Google search in the iOS Now.

Perhaps this decision was somewhat odd, for providing superior application that only exists on Android to its biggest competitor sounds very odd. But look in the mirror of the past, I was never hesitate to give an application with features similar to or better than the Android version (eg Google Maps) to iOS.

The reason is because Google never take profit directly from Android. And Google is actually an advertising company, so that the priority is to get the data and information from the user as much as possible in order to deliver relevant ads that do not care whether the origin of the Android, iOS or other OS.

Washington.Scientists from Washington University in St. Louis proved that bee venom is capable of destroying the Human Immunodeficiency Virus (HIV). This research opens new opportunities and expectations prevention and cure HIV / AIDS.

The results were published in the journal Antiviral Therapy. The research describes how the use of bee venom called melittin and nano particle as a carrier to be able to kill the virus in the blood of a great enemy to human.
