IntroductionThe building of prehospital emergency medical care systems in developing and lower middle-income countries (as defined by the World Bank) is a critical step in those countries’ efforts to reduce unnecessary morbidity and mortality. This

Recent laboratory studies show that adding activated carbon to marine sediments reduces the bioavailability of persistent organic contaminants, such as polychlorinated biphenyls, to benthic organisms. The present work investigates how mixing activate

Perennial pepperweed, found throughout the western United States, reduces biodiversity and causes economic losses in the form of control costs as well as decreased quantity and quality of agricultural yields. The future stream of net benefits of weed

The addition of activated carbon as particulate sorbent to the biologically active layer of contaminated sediment is proposed as an in-situ treatment method to reduce the chemical and biological availability of hydrophobic organic contaminants (HOCs)

Gold and silver show strong evidence of ability to hedge stock portfolios and inflation during the period from 1970 to 2006. However, negative betas are only observed for the 1970s, suggesting that it is the inflation-hedging ability that is the caus

Gold shows the characteristics of a zero-beta asset. It has approximately the same mean return as a Treasury Bill and bears no market risk. Silver also bears no market risk but has returns inferior to Treasury Bills. Both gold and silver show evidenc

Recent laboratory studies show that mixing activated carbon with contaminated sediment reduces the chemical and biological availability of hydrophobic organic contaminants. In this study, we test the effects of varying the activated carbon dose and p
