COMPARISON OF EMISSIONS FROM ON-ROAD SOURCES USING A MOBILE LABORATORY UNDER VARIOUS DRIVING AND OPERATIONAL SAMPLING MODES

Comparison of emissions from on-road sources using a mobile laboratory under various driving and operational sampling modes

Mobile sources produce a significant fraction of the total anthropogenic emissions burden in large cities and have harmful effects on air quality at multiple spatial scales.Mobile emissions are intrinsically difficult to estimate due to the large number of parameters affecting the emissions variability within and across vehicles types.The MCMA-2003

Mechanistic insights revealed by the crystal structure of a histidine kinase with signal transducer and sensor domains.

Two-component systems (TCSs) are important for the adaptation and survival of bacteria and fungi under stress conditions.A TCS is often composed of a membrane-bound sensor histidine kinase (SK) and a response regulator (RR), which are relayed through sequential phosphorylation steps.However, the mechanism for how an SK is switched on in response to
