and other process equipment in a secure web-based environment and allows users to; • Run your process more efficiently. • Improve your operating margins. • Avoid unnecessary shutdowns. • Improve your maintenance management decisions. GAS TURBINE PERFORMANCE is subject to degradation over time. When gas turbine engines are run, they become fouled with airborne contaminants such as oil, pollen, s...

The cost of nosocomial infections in the United States is estimated to be $4 billion to $5 billion annually. Applying a scientifically based analysis to disease transmission and performing a site specific risk analysis to determine the design of the ventilation system can provide real and long term cost savings. Using a scientific approach and convincing data, this paper hypothetically illustra...

the aim of this study was to survey levels of polychlorinated biphenyls (pcbs), polychlorinated dibenzofurans (pcdfs), and polychlorinated dibenzo-p-dioxins (pcdds) in white mullet (mugil curema), common snook (centropomus undecimalis), and acoupa weakfish (cynoscion acoupa), collected at sepetiba bay, rio de janeiro, brazil, march-august 2013. pcbs and pcdd/fs were determined by high resolutio...

A review is presented of how one defines emerging contaminants and what can be included in that group of contaminants which is preferably termed "contaminants of emerging concern". An historical perspective is given on the evolution of the issues surrounding emerging contaminants and how environmental scientists have tackled this issue. This begins with global lead contamination from the Romans...

OBJECTIVES We performed the current study to (1) understand the distribution of culturable airborne bacteria over a one-year monitoring period, (2) confirm places in stations where airborne bacteria are highly detected, (3) understand the factors that affect concentrations of airborne bacteria and (4) compare the distributions of airborne bacteria and fungi in railway stations in Japan. METHO...

hospitalized patients have a potential risk for nosocomial infections. airborne fungi are one of the main causes of fungal infections in this group. the objective of this study was to investigate the concentrations and species of airborne fungi in two general hospitals in shiraz, southern iran. air samples were collected from high-risk wards, using settle plate method. fungal colonies were iden...

Aspergillus, Penicillium and Talaromyces species are frequently cited as contaminants of various substrata often associated with indoor environments. The main purpose this study was to assess the potential pathogenicity aerosol-derived fungi from genera, isolated in rooms for con?servation cultural heritage artefacts, via estimating hemolytic activity. Hemolysis detected 20.58% tested isolates ...
