  2. Ionospheric storm - Wikipedia

    en.wikipedia.org/wiki/Ionospheric_storm

    The intensity of the storm brought the visibility of the aurora to lower latitudes, and it was reportedly seen in places such as Florida and the Caribbean. Ionospheric storms can happen at any time and location. [6] F-region and D-region ionospheric storms are also considered main categories of ionospheric storms. The F-region storms occur due ...

  3. Pneumococcal pneumonia - Wikipedia

    en.wikipedia.org/wiki/Pneumococcal_pneumonia

    Pneumococcal pneumonia is a type of bacterial pneumonia that is caused by Streptococcus pneumoniae (pneumococcus). [1] It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal ...

  4. Sudden ionospheric disturbance - Wikipedia

    en.wikipedia.org/wiki/Sudden_ionospheric_disturbance

    The ionospheric disturbance enhances VLF radio propagation. Scientists on the ground can use this enhancement to detect solar flares; by monitoring the signal strength of a distant VLF transmitter, sudden ionospheric disturbances (SIDs) are recorded and indicate when solar flares have taken place.

    X-ray presentations of pneumonia may be classified as lobar pneumonia, bronchopneumonia, lobular pneumonia, and interstitial pneumonia. [75] Bacterial, community-acquired pneumonia classically show lung consolidation of one lung segmental lobe, which is known as lobar pneumonia. [42]

  6. High-frequency Active Auroral Research Program - Wikipedia

    en.wikipedia.org/wiki/High-frequency_Active...

    The study of these disturbed volumes yields important information for understanding natural ionospheric processes. During active ionospheric research, the signal generated by the transmitter system is delivered to the antenna array and transmitted in an upward direction. At an altitude between 70 and 350 km (43 and 217 mi) (depending on ...

    Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere.

  9. Dust pneumonia - Wikipedia

    en.wikipedia.org/wiki/Dust_pneumonia

    Symptoms of dust pneumonia include high fever, chest pain, difficulty in breathing, and coughing. With dust pneumonia, dust settles all the way into the alveoli of the lungs, stopping the cilia from moving and preventing the lungs from ever clearing themselves. [citation needed] People who had dust pneumonia often died. [1]
