About 75 of myxomas occur in the left atrium of the heart, usually beginning in the wall that divides the two upper chambers of the heart. The rest are in the right atrium. Right atrial myxomas are sometimes associated with tricuspid stenosis and atrial fibrillation . Myxomas are more common in women. About 10 of myxomas are passed down through families inherited . Such tumors are called familial myxomas. They tend to occur in more than one part of the heart at a time, and often cause symptoms at a younger age than other myxomas. Symptoms Symptoms may occur at any time, but most often they accompany a change of body position. Symptoms may include Dyspnea Shortness of breath with activity Platypnoea Difficulty breathing in the upright position with relief in the supine position Cardiac asthma Paroxysmal nocturnal dyspnea Breathing difficulty when asleep Presyncope Dizziness Syncope medicine Fainting Palpitation s Sensation of feeling your heart beat Chest pain or tightness Sudden Death In which case the disease is an autopsy finding The symptoms and signs of left atrial myxomas often mimic mitral stenos ... more details

This was the first Shenzhou spacecraft launched that could have actually carried a human and as such the main objective of the mission was to test the systems required to support a human in space. On board it carried a dummy to simulate physiological signals of a human palpitation , pulse , breath ing, eating , metabolism , and excretion . The launch had been delayed several months due to design changes. It had been planned that Shenzhou 3 would use a new interior design but implementation problems meant reverting to the previous version. The rocket and spacecraft were eventually rolled out on the pad during the Fifth Session of the Ninth National People s Congress and the Ninth National Committee of the Chinese People s Political Consultative Conference in early March 2002. It is thought that Shenzhou 3 changed its orbit twice during the mission. The first was on March 29 at 10 15 Coordinated Universal Time UTC when the aft maneuvering thrusters fired for about 8 seconds putting it into a 330.2 km x 337.2 km orbit. The second was on March 31. Both times were to raise its orbit. Shenzhou 3 operated in a slightly less inclined orbit of 42.40 to the previous Shenzhou 1 and Shenzhou 2 2 flights, which were in about 42.59 inclined orbits. On board were carried 44 different experiments. These included an imaging spectrograph , cloud sensor, radiation sensor, solar ultraviolet monitor, solar constant monitor, atmospheric composition detector, atmospheric density detector, multi ... more details
Infobox Korean name hangul hanja mr Han rr Han Han is a concept in Korean culture attributed as a national cultural trait. Han denotes a collective feeling of oppression and isolation in the face of overwhelming odds. It connotes aspects of lament and unavenged injustice. The minjung theologian Suh Nam dong describes han as a feeling of unresolved resentment against injustices suffered, a sense of helplessness because of the overwhelming odds against one, a feeling of acute pain in one s guts and bowels, making the whole body writhe and squirm, and an obstinate urge to take revenge and to right the wrong all these combined. ref cite book last Yoo first Boo wong title Korean Pentecostalism Its History and Theology year 1988 publisher Verlag Peter Lang location New York isbn 3 820416 64 1 page 221 ref In some occasions, anthropologists have recognized han as a culture bound syndrome culture specific medical condition whose symptoms include dyspnea , heart palpitation , and dizziness .

Others attribute han to class system strictures, such as the distinction between the elite Yangban class and the peasants. Han permeates Korean cultural expression, for example, in Korean shamanism and Pansori . Japanese scholar Kimura claims that modern history such as the Liberation Day Korea liberation by the surrender of Japan to the Allies of World War II Allies rather than to the Korean Liberation Army , the Korean War and the subsequent division of the nation also contribute to the culture as missing glorious history and unresolved han . ref cite bo ... more details

Other members of VAN included, An bal Villac s , Luis Molinari , Hugo Cifuentes and Gilberto Almeida. Maldonado s international presence is largely due to his participation in over a hundred exhibits outside of Ecuador. Born in P ntag , in the Quito district of Ecuador, Maldonado left home at a young age in order to observe and learn from nature. Both nature and the indigenous themes have been a fundamental inspiration for much of his work. Maldonado studied art at the School of Fine Arts in Guayaquil . By 1953, Maldonado was teaching drawing and art history at the American School of Guayaquil. In 1955, Maldonado traveled the Ecuadorian coast painting the people of the coast and landscapes.

notability date February 2012 NACA Report No. 130 Aeronautic Instruments, Section VI, Oxygen Instruments was issued by the United States National Advisory Committee for Aeronautics in 1923. Summary NACA Report No. 130 continues the classification, rating and discussion of aeronautic instruments that was started in NACA Report No. 125 . NACA Reports No. 125 to No. 132, inclusive, were prepared by the aeronautic instrument section of the National Institute of Standards and Technology Bureau of Standards at the request of the National Advisory Committee for Aeronautics. Much of the material was made available through the cooperation of the War and Navy Departments. It has been shown that at heights above 15,000 feet the physical condition of aviators is seriously affected from lack of oxygen, unless artificial means is provided to supply the deficiency. The physiological symptoms are headache, which is usually the first symptom noted, palpitation, fatigue, numbness of the limbs, pains in one or both ears, which may persist for several hours, weakening of the attention, diminished sense of stability, vertigo, faintness, and finally loss of consciousness, with consequently disastrous results unless consciousness is regained before the earth is reached. It has been definitely determined that flying at altitudes of 20,000 feet or more for extended periods cannot be undertaken without serious injury to the central nervous system of the aviator. These physiological symptoms can be almost entirely avoided by supplying to the aviator artificial oxygen during flight. The average man at full atmospheric pressure breathes approximately 16 times per minute. The volume of each inspiration is about one haIf liter, so that 8 liters of air is breathed per minute, of which 1.6 liters is oxygen. This, however, is the minimum required. During flight the aviator is continually in a state of physicaI activity and, therefore, needs more oxygen. It has been found that 4 liters per minute is ... more details

While this rhythm occurs most often in individuals with cardiovascular disease e.g. hypertension , coronary artery disease , and cardiomyopathy and diabetes, it may occur spontaneously in people with otherwise normal hearts. It is typically not a stable rhythm, and frequently degenerates into atrial fibrillation AF . However, it does rarely persist for months to years.
