In nature, pesticides are often present as micropollutants with concentrations too low for efficient biodegradation and growth of heterotrophic pollutant-degrading bacteria. Instead, organic carbon present in environmental dissolved organic matter (eDOM) constitutes the main carbon source in nature. Information on how natural organic carbon affects degradation of pollutants and micropollutants, ...

Contemporary health care relies on electronic devices. These technologies are not ethically neutral but change the practice of care. In light of Sennett's work and that of other thinkers (Dewey, Dreyfus, Borgmann) one worry is that "e-care"-care by means of new information and communication technologies-does not promote skilful and careful ...

Metagenomic characterization of water virome was performed in four Mississippi catfish ponds. Although differing considerably from African swine fever virus (ASFV), 48 of 446,100 sequences from 12 samples were similar enough to indicate that they represent new members in the family Asfarviridae. At present, ASFV is the only member of ...

The decatungstate anion [W(10)O(32)](4-) is widely used as a photocatalyst in different transformations, during which it undergoes one-electron reduction to [W(10)O(32)](5-), possibly protonated; the bi-reduced species [W(10)O(32)](6-) is obtained by ensuing disproportionation. Relativistic DFT calculations were used to predict the UV-VIS spectra and EPR parameters of all such species.
