Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process.
Extract: Government spending has increased substantially in recent years. Consequently, the breakeven oil price rose to $106 a barrel in 2014 from $69 a barrel in 2010. As a result, with the large decline in oil prices, the fiscal deficit has increased sharply and is likely to remain high over the medium-term.
The resulting breakeven ethanol price is then about $2.90 (1.10 X 2.60). If the price of CBOB changes the middle horizontal segment of the demand curve will shift up and down. Finally, the ethanol price in this example is $1.70, which is near present levels for nearby ethanol futures.
