Two Helicopters X, World's Fastest

Their names are both using the letter X. Which one is Sikorksky X2, others named Eurocopter X3.

Both helicopters are capable of flying faster than ordinary helicopters.



Using the body Eurocopter Dauphin, X3 has several modifications from its predecessor's.

As quoted from the site Physorg, X3 adds an extra engine that is used to drive two extra propellers located on the short wing on either side of its body.
Although only a single additional machine, but the plane is now still at the experimental stage that can run faster than ordinary helicopters.

Gliese 581d Planet Ascertained Livable

Gliese 581d, a rocky planet orbiting a giant red dwarf stars (stars with masses lower than the sun and the temperature below 4000 degrees Kelvin) is confirmed as the first planet that meets the requirements to accommodate life.

Planet which is about 20 light-years from Earth is one of our closest neighboring planet. He estimated temperature is warm enough and wet enough to cultivate a similar life-owned planet Earth.

Children suffering Progeria, Old Before Time

Hair loss and does not grow longer, the blood vessels in the head was clear, wizened skin because there is no fatty tissue, are the traits of progeria patients. worse these symptoms occur in children.

Another characteristic is curved and brittle nails, stiffness in the joints, causing bone loss easily cracked or broken bones, delayed tooth growth, are signs of progeria patients. Though it is a symptom in people who enter old age.

Diabetic Mellitus Disease

Diabetes or sugar disease / diabetes is a disease characterized by hyperglycemia (elevated blood sugar levels) are continuous and varied, especially after meals. Other sources mention that the reference to diabetes mellitus is a state of chronic hyperglycemia accompanied by metabolic disorders due to hormonal disturbances, which cause a variety of chronic complications in the eyes, kidneys, and blood vessels.

If the body lacks insulin, the glucose in the blood can not enter the cells to be converted into glycogen, resulting in accumulation of glucose in the blood (hyperglycemia) and finally excreted through the urine (glukosauria).

As a result, the production of urine increased, the patient continues to urinate, feeling very thirsty and losing weight.

Bronchitis Disease

Bronchitis is a respiratory infectious disease that causes swelling of the mucous membrane (mucous membrane) on the parts relatedto the respiratory organs, especially the trachea, bronchial andbronchioles. These organs are in areas related breathing oxygenturnover. In general, Bronchitis affects the respiratory system,especially the lungs. Bronchitis is a respiratory disease thatcauses breathing becomes difficult, congested and sometimespainful. The pain may occur and is associated with swelling thatoccurs in the mucous membrane in the trachea.

Protein Analysis, Kjedahl Method

The Kjeldahl method was developed in 1883 by a brewer called Johann Kjeldahl. A food is digested with a strong acid so that it releases nitrogen which can be determined by a suitable titration technique. The amount of protein present is then calculated from the nitrogen concentration of the food. The same basic approach is still used today, although a number of improvements have been made to speed up the process and to obtain more accurate measurements. It is usually considered to be the standard method of determining protein concentration. Because the Kjeldahl method does not measure the protein content directly a conversion factor (F) is needed to convert the measured nitrogen concentration to a protein concentration. A conversion factor of 6.25 (equivalent to 0.16 g nitrogen per gram of protein) is used for many applications, however, this is only an average value, and each protein has a different conversion factor depending on its amino-acid composition. The Kjeldahl method can conveniently be divided into three steps: digestion, neutralization and titration.

New Particle Discovered?

Researchers at Fermilab recently discovered a particle that had never previously encountered.

Although this particle is not a Higgs boson, which has been sought by physicists, but these findings are suspected to be a new proof of the existence of new particles in nature.

As reported by MSNBC, researchers discovered these particles through atomic-breaking tool in the physics laboratory Fermilab Tevatron, in Batavia, Illinois, United States.
