Immobilization of degradative bacteria in polyurethane-based foams: embedding efficiency and effect on bacterial activity

Description: The immobilization of TCE-degrading bacterium Burkholderia cepacia was evaluated using hydrophilic polyurethane foam. The influence of several foam formulation parameters upon cell retention was examined. Surfactant type was a major determinant of retention, with a lecithin- based compound retaining more cells than pluronic or silicone based surfactants. Excessive amounts of surfactant led to increased washout of bacteria. Increasing the biomass concentration from 4.8% to 10.5% caused fewer cel… more

Bench scale silver recovery unit for the MEO system

Description: Mediated electrochemical oxidation (MEO) is a process for treating low-level radioactive, organic, mixed wastes. When treating chlorinated organic compounds, MEO generates AgCl which needs to be recovered, converted into AgNO{sub 3}, and sent back to MEO for reuse. A silver recovery process developed in the lab-scale unit has been scaled up to bench scale 30 times bigger; conversion efficiencies are 98% for both. This paper reports the operational experience of the bench scale unit.

Characterization of polyxylylenes with solid state {sup 13}C nuclear magnetic resonance spectroscopy

Description: Polyxylylenes are thermoplastics used as encapsulants for electronic devices. Five polyxylylenes were prepared by pyrolysis of [2.2]paracyclophanes and characterized by solid state {sup 13}C NMR spectroscopy. The chemical shift data, in combination with interrupted decoupling experiments, allowed assignment of resonances to their carbon sources in the polymers. This confirmed the integrity of the xylylene building block in the polymers and is consistent with linear polymers. No crosslinking cou… more

Krafting an agreement: Negotiations to reduce pollution from the Nordic pulp industry, 1985--1989

Description: International environmental accords frequently contain obligations that may be easily satisfied by their signatories. Observers have speculated why it is in a state`s interests to sign agreements that lack strict conditions, but policy analysts lack a coherent model explaining how such agreements are formalized. Knowledge, values, and authority are key forces that elucidate how environmental accords are developed with provisions that are easily executable. This dissertation examines the formula… more
