Emerging halogenated acetic acids (HAAs), especially mixed halogenated acids such as chlorobromo-, chloroiodo- and bromoiodo-acetic acids, are unregulated disinfection by-products in drinking water. Because these compounds are hydrophilic and strongly acidic, they are difficult to detect at trace levels using approved analytical methods. In the present study, 13 HAAs were effectively separated ...

ATPase activity and ATP-Pi exchange of unregulated (without tropomyosin-troponin) and regulated (with tropomyosin-troponin) acto-HMM were measured in media containing 0.2 mg/ml actin, HMM, and (when present) tropomyosin-troponin, 2 mM MgCl2, 10 mM KCl, 2 mM NaN3, 10 mM Pi (pH 7.0), 3 MM ATP. The following mean values for ATPase activity and for the rate of incorporation of Pi into ATP (each per...

Regional water pollution and use of unregulated water sources can be an important mixed metals exposure pathway for rural populations located in areas with limited water infrastructure and an extensive mining history. Using censored data analysis and mapping techniques we analyzed the joint geospatial distribution of arsenic and uranium in unregulated water sources throughout the Navajo Nation,...

Karl Polanyi wrote The Great Transformation in 1944 which analysed the double movement Europe experienced, from a situation where the market was heavily regulated and controlled in the eighteenth century to a virtually unregulated market in the nineteenth century, and the huge transformation in which the market was once more brought under control as a reaction to the poverty, unemployment and i...

This paper compares patterns of hiring and separations in regulated and unregulated labor markets over the last two decades in Brazil, with an eye toward gauging the effects of employment protection on employment adjustment over the business cycle. Since the difference between the sectors is stark and well-defined, the consequences of employment protection on flows through the labor market are ...
