A dual ejector system with an intermediate Evaporating Tube was circulated at 11 laboratories to measure the Particle Concentration Reduction Factors (PCRF) at 30, 50 and 100 nm (as required by the legislation). In addition to this "Golden" Volatile Particle Remover (GVPR), a PALAS DNP 3000...

The PN-PEMS is considered a "black box" where efficiency tests and linearity have to be checked with thermally stable soot like aerosol. The efficiency is checked with monodisperse aerosol. The most straight forward way is to check the efficiency of the complete PN-PEMS but checking the thermal...

Regulation 2016/427 introduced on-road testing with Portable Emissions Measurement Systems (PEMS) to complement the laboratory Type I test for the type approval of light-duty vehicles in the European Union. A NOx conformity factor of 1.5 will apply from January 2020/2021. This conformity factor...

The measurement of food security resilience (FSR) to shocks is yet hampered by inherent aspects of its complexity along with that of food security assessment itself. Yet, there is an urgent need for scientific evidence on which to base decision-making and policies to build resilience. Niger is...

Transmission measurements have been performed at the time-of-flight facility GELINA to determine neutron resonance parameters for 51V. The measurements have been carried out at a 50 m transmission station at a moderated neutron beam using a Li-glass scintillator with the accelerator operating at...

To track the real progress towards the energy efficiency targets, this report examines the drivers behind EU energy consumption trends using index decomposition analysis. Energy consumption trends are driven by several factors beyond energy efficiency improvements, including economic activity,...

The objective of this study is to provide a new evidence on time-varying equity market integration, employing alternative econometric specifications of the conditional covariance process. Differently from the current literature on the topic, we specify alternative econometric models for the...

Eight Laboratories of AQUILA (Network of European Air Quality Reference Laboratories) met for a laboratory comparison exercise in Ispra (IT) to evaluate their proficiency in the analysis of inorganic gaseous air pollutants (NO, NO2, SO2, CO and O3). On the basis of agreed criteria, 79.3% of the...
