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.
But there is a wide gap between the prices at which different producers break even. A modest oil-price recovery and currency devaluations have lowered breakeven prices for countries like Russia and Nigeria, but some petrostates still need oil prices above $100 a barrel to balance their budgets. modest oil-price recovery and currency devaluations have lowered breakeven prices for countries like Russia and Nigeria, but some petrostates still need oil prices above $100 a barrel to balance their budgets.
