This paper presents a regionalized vulnerability curve-building approach to vulnerability and risk assessment of wheat subjected to drought that uses the Environmental Policy Integrated Climate (EPIC) model and statistical analysis. We defined wheat vulnerability as the degree to which a wheat production system is likely to experience yield loss due to a perturbation or drought hazard. Wheat vu...

A solid-phase extraction (SPE) method for sample clean-up and preconcentration followed by reversed-phase high-performance liquid chromatography (RP-HPLC) with uv detection is reported for determination of polycyclic aromatic hydrocarbons (PAHs) in the caspian seawater. A good resolution was obtained using acetonitrile:water (40:60) as mobile-phase for separation of these compounds. The effect ...

Representations of quantitative geography, both by practitioners and by others, have tended to associate quantification with empiricism, positivism, and the social and academic status quo. Qualitative geography, by contrast is represented as nonempiricist or postempiricist, sensitive to complexity, contextual, and capable of empowering nonmainstream academic approaches and social groups. Attemp...
