The most common symptoms of Pneumothorax are chest pains. The chest pains can be sharp, dull, or stabbing. Some other symptoms of Pneumothorax are shortness of breath, rapid breathing, and coughing.
A Pneumothorax can occur for no obvious reason (spontaneous). It is typically men who are tall (or perhaps have long torsos), between the ages of 20 and 40 who present a spontaneous pneumothorax.
Small air blisters (blebs) can develop on the top of the surface of the lungs. These blebs sometimes burst — allowing air to leak into the pleural space that surrounds the lungs, causing the lung to collapse.
Otherwise, it can be caused by blunt or penetrating injuries or lung diseases that result in the lung leaking air into the pleural cavity.
Consuming cannabis via smoking is also related to victims of a pneumothorax.
Simple Pneumothorax will heal by itself. Complex pneumothorax will need medical attention. One should treat respiratory problems as soon as they occur.
Closed pneumothorax is when air or gas gets in the pleural space without any outside wound. This sometimes happens when the lung is already injured somehow, like from diseases such as cancer or cystic fibrosis. Cystic fibrosis is a disease in the lungs. Glands in the body make large amounts of thick mucus. The mucus blocks ducts and passageways.
The most common cause of closed pneumothorax is called spontaneous pneumothorax. The cause of spontaneous pneumothorax is not known.
Open pneumothorax is when air gets into the pleural space from an injury to the chest. This can happen with stab wounds, like from a knife. It can also happen after a gunshot injury. The injury is most dangerous if the wound lets air in when the injured person (or animal) breathes, but does not let it back out. Sometimes this is called a "sucking chest wound."
Electroluminescence
Electroluminescence (EL) is an optical and electrical event in which a material emits light in response to an electric current passed through it, or to a strong electric field.
The electric energy is absorbed by electron in the ground state and is excited to the higher state of energy called the excited state.The excited state is not the stable state and the electron jumps back to the ground state and emits the photon related to the bandgap of the material.Daughter of the Forest
Daughter of the Forest is a fantasy novel by Juliet Marillier first published in 1999 It is based on "The Six Swans" (a story that has many versions, one of which is by the Brothers Grimm). A girl must sew six shirts from a painful plant in order to save her brothers from a witch's curse. She must not speak until the task is finished.
Sorcha, the seventh child of Irish Lord Colum of Sevenwaters, has been raised by her six older brothers. Having lost her mother at birth, Sorcha is almost ignored by her father. Her father's new wife, the Lady Oonagh, attacks Sorcha and her brothers. Sorcha alone is able to flee into the forest and escape. Sorcha's brothers, however, have been turned into swans.
The story is a twist on the classic tale of "The Six Swans." Sorcha learns that if she can spin six shirts from a painful plant she can free her brothers from the spell. But she must not speak until the last one has been finished. Sorcha agrees to this and spends several years in the forest hiding as she works on the shirts.
After several years of hard work, Sorcha is saved from drowning by a British lord, Hugh of Harrowfield (known as "Red"). When Red returns to Britain, Sorcha accompanies him. Red believes that Sorcha knows something about his brother, Simon. Sorcha had nursed Simon back to health after his capture by Lord Colum. Sorcha stays with Red as she works on the shirts.
While in Britain, Sorcha finds a new danger in the form of Lord Richard, Red's uncle. Sorcha must fend off the attacks of Richard as she works to save her brothers.
Sonic Adventure
Sonic Adventure is a video game from the Sonic the Hedgehog series. It was the very first Dreamcast game. It was released in Japan on November 27, 1998, in North America on September 9, 1999 and in Europe on October 14, 1999. It is the first Sonic game to have 3D surroundings, instead of 2D surroundings like the other Sonic games had. It was released in Japan as one of five launch titles. It also has a sequel called Sonic Adventure 2.
The object of the game is to get all of the Chaos Emeralds by playing different characters from the Sonic series, in order to defeat Dr. Eggman. Each character has their own level, each with a specific purpose. For example, Knuckles has to find and put together all of the pieces of the Master Emerald. The list of playable characters are:
Sonic Adventure DX: Directors Cut is an advanced version of Sonic Adventure released for the Nintendo GameCube and Microsoft Windows in 2004. It was later released on PSN, XBLA and Steam. It contained a new "Mission Mode", a Mini-Game collection [only on GameCube and Windows versions] and allows the player to play as Metal Sonic once they get all 130 emblems. It is famous for being full of glitches.
Hyracotherium
Hyracotherium was previously called "Eohippus" (meaning "dawn horse"). It is a Eurasian species, a Palaeothere. That group is ancestral to the horses and brontotheres. Therefore, it is not the same animal as "Eohippus", which is the earliest horse.
"Hyracotherium" lived during the early Eocene epoch, about 5545 million years ago. It lived in the northern hemisphere in Asia and Europe. The first fossils of this tiny animal were found in England by Richard Owen in 1841 and named "Hyracotherium".
The original type species "H. leporinum" is now regarded as an "Eohippus". So that name has been brought back to describe the early proto-horse found in North America.
Hurricane Keith
Hurricane Keith was the strongest hurricane of the 2000 Atlantic hurricane season. Keith struck Belize and Mexico before it died on October 6. Keith killed 24 people and left $225 million in damage. Most of this damage happened in Belize. It was because it struck Belize while stronger than when it struck Mexico.
The beginning of the hurricane was from a tropical wave that moved into the Atlantic Ocean off of Africa on September 16. The wave moved across much of the Caribbean Sea, until September 28, at that time it became Tropical Depression Fifteen. Fifteen moved a little northwest and became Tropical Storm Keith on September 29.
Keith changed its course and moved west. On September 30 Keith became a hurricane. Keith rapidly gained strength and later on September 30, Keith reached its highest wind speed with which at 140 mph. The hurricane was blocked and was forced to make a loop.
Since Keith was close to land, the block caused Keith to weaken a lot. On October 2 as a weak hurricane, Keith made landfall in Ambergris Caye, Belize. The next day, Keith made another landfall in Belize, this time in Belize City as a very strong tropical storm.
Keith moved over Belize and the Yucatan Peninsula and weakened to a tropical depression. Tropical Depression Keith moved off of the Peninsula and into the Gulf of Mexico, where it quickly became a tropical storm again.
On October 4, Keith again became a hurricane. Hurricane Keith made its last landfall in Mexico near Tampico in Tamaulipas on October 5. Keith weakened over Mexico until it finally died on October 6.
The name Keith was retired in the Spring of 2001. The name Kirk was put on the list in 2006, but Kirk was not used, so it must be used again in 2012.
Degree (mathematics)
The degree of a polynomial formula_1, represented by the symbol formula_2, is the highest exponent that occurs inside that polynomial.
For example, if we look at the polynomial formula_3, then we can see that the degree of this polynomial is 3, because the highest power in the variable x is 3. It occurs in the term formula_4.
