We as engineers expect building codes to advance the state of the art with each successive edition. The 2009 International Building Code (IBC) and the Building Code Requirements for Structural Concrete (ACI 318-08) have significant revisions affecting the design of ti...

In 2010, two reports have provided estimates of maternal mortality ratios (MMR) for different countries (1, 2). Hogan et al. have reported a decreasing trend for MMR in Iran from 101 (per 100000 live births) in 1980, 64 in 1995, and 36 in 2000 to 28 in 2008 (1). In the World Health Statistics 2010, two different estimates have been provided for most of the countries; one countryreported and one...
