چکیده

The overall objective of this collaborative project has been to determine the rates and mechanisms whereby microbes dissolve Fe(III)(hydr)oxides in aerobic soil environments. Information about the rates and mechanisms of Fe(III)(hydr)oxide dissolution is fundamental for a wide range of hydrobiogeochemical processes, yet little is known about the mechanism of dissolution promoted by siderophore-producing microorganisms. Fe(III)(hydr)oxides sorb radionuclides and organic contaminants; thus their dissolution may cause remobilization of these sorbed pollutants. The specific research objectives pursued at Berkeley were: (1) dissolution of Al-substituted goethites, (2) dissolution mechanisms of goethite, and (3) effects on adsorbed trace metals. The results obtained were reported in five technical journal articles:

The Pill is Mightier Than the Sword

One determinant of peace is the role of women in society. Some studies suggest that a young age structure, also known as a “youth bulge” can facilitate conflict. Population growth and age structure are factors amenable to change in a human rights context. We propose that policies which favor voluntary family planning and the education of women can ameliorate the global burden of disease associa...
