Nitrosamine formation has been associated with wastewater-impacted waters, but specific precursors within wastewater effluents have not been identified. Experiments indicated that nitrosamines form in low yields from quaternary amines, and that the nitrosamines form from the quaternary amines themselves, not just lower order amine impurities. Polymeric and benzylated quaternary amines were more...
There has been much research on codes over Z4, sometimes called quaternary codes, for over a decade. Yet, no database is available for best known quaternary codes. This work introduces a new database for quaternary codes. It also presents a new search algorithm called genetic code search (GCS), as well as new quaternary codes obtained by existing and new search methods.
Wireless sensor networks have gained considerable attention in the past few years. They have found application domains in battlefield communication, homeland security, pollution sensing and traffic monitoring. As such, there has been an increasing need to define and develop simulation frameworks for carrying out high-fidelity WSN simulation. In this paper, we identify the threats and vulnerabil...
It was reported in previous studies that inhibitory concentrations of certain chelating or complexing agents did not inhibit several microorganisms when these agents were tested simultaneously (Feeney, 1951; Feeney and Nagy, 1952). Amounts of the metal-binding agents which were strongly inhibitory when tested alone were necessary in order to obtain these mutual preventions of inhibitory action....

BACKGROUND According to the Wonca International Dictionary for General/Family Practice Quaternary Prevention is defined as: 'Action taken to identify patient at risk of overmedicalization, to protect him from new medical invasion, and to suggest to him interventions, which are ethically acceptable.' The concept of quaternary prevention was initially proposed by Marc Jamoulle and the targets wer...
