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.
Costs should not have gone up at the same rate as the speculative price of oil. Total breakeven costs went up by 17.4% per year from 2000 ($18/bbl) to 2008 ($65/bbl). This has resulted in a continued decrease in sanctioned projects. Now costs must come down.
