Ear pain with several weeks of IV and oral antibiotics, usually fluoroquinolones. Acute otitis media is an infection of the middle ear. More than 80% of children experience at least one episode of otitis media by age 3 years. Acute otitis media is also most common in these first 3 years of life, though older children may also experience it. The most common causative bacteria are "Streptococcus pneumoniae", "Haemophilus influenzae", and "Moraxella catarrhalis". Otitis media often occurs with or following cold symptoms. The diagnosis is made by the combination of symptoms and examination of the tympanic membrane for redness, bulging, and/or a
Membrane gas separation can be economically competitive with older and more common technologies such as amine-based absorption. Currently, both membrane and amine-based absorption processes can be designed to yield a 90% CO capture rate. For carbon capture at an average 600 MW coal-fired power plant, the cost of CO capture using amine-based absorption is in the $40–100 per ton of CO range, while the cost of CO capture using current membrane technology (including current process design schemes) is about $23 per ton of CO. Additionally, running an amine-based absorption process at an average 600 MW coal-fired power plant consumes about 30% of the
