We have shown that urea-extracted cell wall of entomopathogenic Bacillus sphaericus 2297 and some other strains is a potent larvicide against Culex pipiens mosquitoes, with 50% lethal concentrations comparable to that of the well-known B. sphaericus binary toxin, with which it acts synergistically. The wall toxicity develops in B. sphaericus 2297 cultures during the late logarithmic stage, earl...

The thienopyrimidinone 5,6-dimethyl-2-(4-nitrophenyl)thieno[2,3-d]pyrimidin-4(3H)-one (DNTP) occupies the interface between the p66 ribonuclease H (RNase H) domain and p51 thumb of human immunodeficiency virus reverse transcriptase (HIV RT), thereby inducing a conformational change incompatible with catalysis. Here, we combined biochemical characterization of 39 DNTP derivatives with antiviral ...

This paper investigates the informational requirements of resource allocation processes in public goods economies with any number of firms and commodities. We show that the Lindahl mechanism is informationally efficient in the sense that it uses the smallest message space among smooth resource allocation processes that are informationally decentralized and realize Pareto optimal allocations ove...

Following the 1900 congress in Paris, the beginning of the 20th century saw comparative law emerge as a significant discipline. This paper suggests that the early 21st century is seeing the decline, or maybe even the ‘end’, of comparative law. In contrast to other claims which see the 21st century as the ‘era of comparative law’, there are at least four trends which give rise to pessimism: ‘the...

Fractionation of stable carbon isotopes upon degradation of trichlorobenzenes was studied under aerobic and anaerobic conditions. Mineralization of 1,2,4-trichlorobenzene by the aerobic strain Pseudomonas sp. P51 which uses a dioxygenase for the initial enzymatic reaction was not accompanied by a significant isotope fractionation. In contrast, reductive dehalogenation by the anaerobic strain De...
