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).

The scientists discovered a strange creature shaped phallus found in the fossil site in Canada. Animals that have been identified as Spartobranchus tenuis, a species of the Cambrian period were previously unknown to science.

According to the researchers, this bizarre creature looked like the acorn worms that exist today. Their study, published in the journal Nature, is the first description of the prehistoric animals.

The remains of soft-bodied worm is found in the Burgess Shale fossil beds in Yoho National Park, Canada. Today for the first time researchers studied 505 million year old fossil animal life researching odd detail. "Many sea creatures such as worms historic size. But unlike these segmented worms. It has three distinct body segments," said Dr. Christopher Cameron, a team of researchers from the University of Montreal, Canada.

According to Dr. Cameron, strange worm is shaped like a phallus comprising heads shaped snout muscles, and in front there is a section ends with a tie neck and a long tail that has gill slits. His body ends in a rounded structure that might help him anchored to the sea.

S. tenuis reveal important evolutionary link between two groups of different animals: Enteropneusts and pterobranchs. The origins of the two groups of marine animals have been confiscated interest of scientists since opening its discovery in the 19th century.

New research suggests that S. tenuis is a relatively ancient group of animals. "It's surprising how similar fossils S. tenuis with modern acorn worms. Unless they also form fibrous tubes," said Dr. Cameron.

New particles discovered last year of the world's largest atom indeed the Higgs Boson. The scientists reported today at the annual conference Rencontres de Moriond, Italy.

Some physicists announced in July last year with 99 percent certainty that they have discovered a new elementary particle weighing about 126 times the mass of the proton. Higgs also referred to as the "god particle", even though many scientists disappointed with this designation.

However, two of the CMS and ATLAS experiments have not gathered enough data to say for sure that the Higgs boson particle. The last piece of the puzzle that has not been found to be predicted by the standard model, the theory of modern physics. And now, after collecting data two and a half times more in the LHC, physicists say that it is the Higgs particle.

"The initial results with 2012 data sets are magnificent and for me, it's definitely the Higgs boson even though we still have a long process to find the Higgs boson this kind," said CMS spokesman, Joe Incandela. Meanwhile, Dave Charlton, ATLAS spokesperson agreed that the new results point to the new particle has a spin-parity of the Higgs boson as in the standard model which refers to the quantum property of elementary particles.

To confirm the Higgs boson particle, physicists collect data that would reveal the quantum nature and how it interacts with another particle. For example, the Higgs particle should have no spin and parity. Or measure how the behavior of reflection to be positive. Both are supported by data from the ATLAS and CMS experiments.

Detecting the Higgs boson is very rare, with only watching one for every 1 trillion proton-proton collisions. For this reason, the LHC physicists need more data to understand all the ways in which the Higgs decays.

Physicists say that the Higgs boson could read the doom of the universe in a very distant future. That is because the mass of the Higgs boson is an important part of the calculations that indicate the space and time in the future.

 
Of course, you often hear the term following the term GPRS, EDGE, UMTS, HSDPA. Do you know what is meant by the term teersebut term? Require more advanced technology to continue holding the renewal, the following are also in the field of data access.

GPRS is the first generation Edge followed by rather quickly by providing services and 3G services deliver the fastest and 3.5G technologies now finally get rid of all to deliver extremely fast service to access the data, and may be present 4G services.

These differences GPRS Data Access> EDGE> 3G/UMTS> 3.5G/HSDPA:

GPRS (General Packet Radio Service): a technology that is used for sending and receiving data packets. GPRS is often referred to as 2G technologies. Facilities provided by GPRS: e-mail, MMS (picture messages), browsing, internet. In theory, GPRS provide access speeds between 56kbps to 115kbps.

EDGE (Enhanced Data for Global Evolution): the development of GSM technologies, an average speed of 3kali GPRS speeds. Access speed EDGE is theoretically around 384kbps. Facilities provided as GPRS EDGE (e-mail, MMS, and browsing).

UMTS (Universal Mobile Telecommunications Service): further development of the EDGE. UMTS is often called the third-generation (3G). In addition to providing Internet access facility (e-mail, MMS, and browsing), UMTS also provides video streaming, video conferencing, and video calling *). In theory UMTS access speeds around 480kbps.

HSDPA (High Speed ​​Downlink Packet Access): a further development of 3G data access. HSDPA is often referred to as generation 3.5 (3.5G) HSDPA for 3G is still running on the platform. In theory, HSDPA data access speeds like 480kbps, but we can be sure that the data access through UMTS HSDPA superior

 
Recently, researchers Department of Ecology and Evolutionary Biology University of Arizona struck by a DNA sample of African-American men in South Carolina named Albert Perry.

They were surprised because of the results of the analysis they did, the Y chromosome of Perry was not related to the chromosomes of the other samples, and allegedly separated from the family tree when modern humans evolved yet.

"Analysis indicates that leg of the Y chromosome lineage about 338,000 years ago, when there was the evolution of modern human anatomy," said Michael Hammer, professor of the University of Arizona that involved research.

"These findings encourage the existence of ancestral Y chromosome to 70 percent to the rear," added Discovery Hammer as quoted on Thursday (07/03/2013).

Driven curiosity, Hammer and his team send DNA samples to the man in the family tree sorted (sequencing). The process of sequencing performed by Fernando Mendez, a post-doctoral researcher at the University of Arizona.

In the process, Mendez uses more than 240,000 pairs of chromosome Y. Mendez sequencing results showed the similarity between the DNA samples of African-American men in South Carolina and a remote tribe living in western Cameroon, the tribe Mbo.

Hammer warned, this finding does not mean that all human beings in the world originated from a common ancestor who lived in the west of Cameroon.

"There is a misconception that states that the revelations of kinship and genetic information from one location to reflect the diversity of the population. Finding it states that there are many genetically isolated communities that protect human diversity," said Hammer.

Hammer said the other Y chromosome is likely to be found, again pushing back the age of the Y chromosome. These findings have broad implications, asserts that there is no so-called "mitochondrial Eve" or "Y-chromosome Adam". Humans as a whole is not exactly coming from a man who lived in the same time period evousi humans.
