In-Use Emissions Testing of Diesel-Driven Buses in Southampton:Is Selective Catalytic Reduction as Effective as Fleet Operators Think? [PDF]

, 2018
Despite the continuously tightening emissions legislation, urban concentrations of nitrogen oxides (NOx) remain at harmful levels. Road transport is responsible for a large fraction, wherein diesel engines are the principal culprits.

Real World Driving: Emissions in Highly Congested Traffic [PDF]

SAE Technical Paper Series, 2017
<div class="section abstract"><div class="htmlview paragraph">The emissions from vehicles in real world driving are of current concern, as they are often higher than on legislated test cycles and this may explain why air quality in cities has not improved in proportion to the reduction in automotive emissions.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Contribution of Cold Starts to Real-World Trip Emissions for Light-Duty Gasoline Vehicles

Atmosphere, 2022
For catalytic converter-equipped light-duty gasoline vehicles (LDGV), the hot-stabilized tailpipe emissions for pollutants such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) are well controlled.
