Satire and Silence Under Authoritarian Rule: Cotton and Pesticide Perceptions in Tajikistan
Journal of Agrarian Change, EarlyView.ABSTRACT Over the past 70 years, agricultural chemicals have become a mainstay of cotton farming in Central Asia. This growing reliance on agrochemicals has not remained uncontested. This article analyses the politics of pesticides in Soviet and post‐Soviet Tajikistan by examining how, and to what extent, pesticides have featured in graphic satire, an ...

Enhancement of Extraction of Uranium from Seawater
, 2016 Even at a concentration of 3 μg/L, the world’s oceans contain a thousand times more uranium than currently know terrestrial sources. In order to take advantage of this stockpile, methods and materials must be developed to extract it efficiently, a difficult task considering the very low concentration of the element and the competition for extraction by

The isotope geochemistry of uranium: Igneous petrology, ore deposits, and groundwater contamination [PDF]
, 2010 This study applies high precision 238U/235U measurement techniques two three geologic settings: basalt differentiation, uranium ore genesis, and the remediation of a uranium-contaminated groundwater system. In the latter two cases, 238U/235U is used as a
