PCR for bioaerosol monitoring: sensitivity and environmental interference

PCR for bioaerosol monitoring: sensitivity and environmental interference.

The PCR technique has potential for use in detection of low concentrations of airborne microorganisms. In this study, the sensitivity of PCR and its susceptibility to environmental interference were assessed with Escherichia coli DH1 as the target organism. Air samples, containing environmental bioaerosols, were collected with AGI-30 samplers and seeded with E. coli DH1 cells. Parallel studies ...

Sensitivity Analysis for Environmental Models and Monitoring Networks

Statistical sensitivity analysis is shown to be a useful technique for assessing both multivariate environmental computer models and environmental statistical spatio-temporal models in the perspective of risk assessment. Methods are reviewed and extended to cover with two applications which are reported as case studies. The rst, related to waste water bio lters for heavy metals, is aimed at ass...

Interference Localisation within the GNSS Environmental Monitoring System (GEMS)

Due to their low-power levels, GPS signals are very susceptible to interference from either intentional or unintentional sources. This vulnerability is further aggravated by the increased reliance of the civilian infrastructure on GPS for time synchronization. This brings about the pressing need for detection and localisation of the interferers in real-time to prevent disturbance to everyday op...

Interference and Sensitivity Analysis.

Causal inference with interference is a rapidly growing area. The literature has begun to relax the "no-interference" assumption that the treatment received by one individual does not affect the outcomes of other individuals. In this paper we briefly review the literature on causal inference in the presence of interference when treatments have been randomized. We then consider settings in which...
