The quantity h, now known as the Planck constant, is a universal constant with the approximate value of 6.626 X 10^-34 Js. Max Planck assumed that the radiation energy is emitted in discrete packets called quanta rather than in a continuous way. The energy E of the quantum is related to the frequency Î½ by E = hÎ½.

1 Some patients with anemia have no symptoms. 2  Those that do have symptoms may. 3  feel tired, 4  become easily fatigued, 5  appear pale, 6  have a feeling of a heart racing, 7  feel short of breath, and/or. 8  have worsening heart problems. 9  Anemia can be detected by a simple blood test called a complete blood cell count (CBC).
Other symptoms of anemia can include bleeding, vomiting blood, black tarry stools (melana), fever, severe bone pain, abdominal pain, weight loss, loss of appetite, and depression.Symptoms can also include flu-like symptoms, muscle aches, vomiting, and diarrhea.Because anemia is a symptom of an underlying disease, condition or disorder, some of which can be serious, any symptoms of anemia should be evaluated by a physician or other licensed health care provider....more about Anemia Â».ymptoms can also include flu-like symptoms, muscle aches, vomiting, and diarrhea.
