BACKGROUND The composition of diesel engine exhaust (DEE) varies by engine type and condition, fuel, engine operation, and exhaust after treatment such as particle traps. DEE has been shown to increase inflammation, susceptibility to infection, and cardiovascular responses in experimentally exposed rodents and humans. Engines used in these studies have been operated at idle, at different steady...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Major environmental stressors of boreal and sub-arctic rivers are hydrological changes and global warming and both factors will significantly influence the future evolution of the river chemistry in high latitudes. We tested the hypothesis...

Introduction / objectives Reprocessing single use devices is the process to be applied to hospital/medical objects which allows their reuse; in order to reuse them it is necessary to include steps in order to ensure that the catheters are clean, without organic matter, reducing the microbial load, pyrogens and biofilm. To develop and validate a cleaning protocol for objects from a cardiology se...

ABSTRACT The organic growth of the web has led to web sites that exhibit a large variety of properties. We conduct a largescale study to gain quantitative insights into the browser-side effects of the structure and behavior of thousands of the most popular web sites. We find that 50 % of web pages load more than 100 resources from more than 17 distinct hosts and make the browser process more th...

Microbial fuel cells are obtaining increased attention in wastewater treatment technology because of provision of effective treatment in presence of a low organic load through continuous electrical power supply. This paper studies the voltage reutilization performance of a microbial fuel cell using recycled wastewater from its treatment process as an anodic fuel. The experimental results show t...
