Trace metals, such as nickel (Ni), are often found associated with ferrihydrite (Fh) in soil and sediment have been shown to redistribute during Fe(II)-catalyzed transformation of Fh. Fh, however, is inhibited when natural organic matter (NOM) To explore whether NOM affects the behavior Ni we tracked distribution, Fe atom exchange, mineral Fh coprecipitated Suwannee River (SRNOM-Fh). As expecte...

The increasing amount of plastic debris in the environment and its disintegration into submicrometric particles are cause for concern. Due to colloidal nature nanoplastics, their environmental fate should be investigated separately from that microplastics. Abiotic factors greatly influence stability nanoplastics. This will affect residence time hydrosphere. Therefore, we behavior two different ...

This paper presents the first deterministic selfstabilizing network orientation algorithms. We present three protocols for arbitrary and asynchronous networks. All the protocols set up a chordal sense of direction in the network. The protocols are self-stabilizing, meaning that starting from an arbitrary state, the protocols are guaranteed to reach a state, in which all edge labels (assigned to...

We study the supergravity hybrid inflation model of Ref. [1] in the presence of a modulus field. The η-problem is solved by a shift symmetry for the inflaton, which protects the inflaton mass even in the presence of the modulus field. Inflation is (nearly) unaffected by moduli stabilization, provided the scale of supersymmetry breaking in the post-inflation vacuum is small. Therefore the model ...

We estimate the impacts of various types of government payments to U.S. agriculture on different components of farm household consumption. Using 2003 to 2005 data from the Agricultural Resource Management Survey (ARMS), we show that marginal rates of consumption differ by consumption category and income source, including different types of farm program payments. The results suggest that farm ho...
