Information on the origin of pollution constitutes an essential step air quality management as it helps identifying measures to control pollution. In this work, we review most widely used source-apportionment methods for management. Using theoretical and real-case datasets study differences among these explain why they result in very different conclusions support planning. These are a consequence intrinsic assumptions that underpin methodologies determine/limit their range applicability. We...
The 2008 European Air Quality Directive (AQD) (2008/50/EC) encourages the use of models in combination with monitoring a range applications. It also requires Member States to design appropriate air quality plans for zones where does not comply AQD limit values. In order cope these various elements, wide different modeling methods have been developed and applied by EU last decade assess effects local regional emission abatement policy options on human health. However, an overall review...
Residents of large European cities are exposed to NO2 concentrations that often exceed the established air quality standards. Diesel cars have been identified as a major contributor this situation; yet, it remains unclear which levels NOX emissions diesel decrease effectively mitigate urban pollution across Europe. Here, we take continental perspective and model in generic street canyon 8 for various emission scenarios. We find reduction on-road Euro 6 level can general regional thereby...
In the framework of Forum for Air Quality Modelling in Europe (FAIRMODE), a modelling intercomparison exercise computing NO2 long-term average concentrations urban districts with very high spatial resolution was carried out. This undertaken district Antwerp (Belgium). quality data includes recorded air monitoring stations and 73 passive samplers deployed during one-month period 2016. The domain 800 × m2. Nine teams participated this providing results from fifteen different applications based...
The photoproduction of η-mesic 3He has been investigated using the TAPS calorimeter at Mainz Microtron accelerator facility MAMI. total inclusive cross section for reaction γ3He→ηX measured photon energies from threshold to 820 MeV. and angular differential coherent η sections have extracted up 745 A resonancelike structure just above production with an isotropic distribution suggests existence a resonant quasibound state. This is supported by studies competing decay channel such nucleus...
The photoproduction $p(\ensuremath{\gamma}{,K}^{+})\ensuremath{\Lambda}$ process is studied within a field-theoretic approach. It shown that the background contributions constitute an important part of reaction dynamics. We compare predictions obtained with three plausible techniques for dealing these contributions. appears extracted resonance parameters drastically depend on applied technique. investigate implications corrections to functional form hadronic factor in contact term, recently...
The reaction gammap-->pi(0)gamma'p has been measured with the TAPS calorimeter at Mainz Microtron accelerator facility MAMI for energies between sqrt[s]=1221-1331 MeV. cross section's differential in angle and energy have determined photon gamma' three bins of excitation energy. This channel provides access to magnetic dipole moment Delta(+)(1232) resonance and, first time, a value mu(Delta(+))=[2.7(+1.0)(-1.3)(stat)+/-1.5(syst)+/-3(theor)]mu(N) extracted.
The annual NO2 concentrations in many European cities exceed the established air quality standard. This situation is mainly caused by Diesel cars whose NOx emissions are higher on road than during type approval laboratory. Moreover, fraction of modern diesel appears to have increased as compared previous models. In this paper, we assess 1) which level distance-specific should be reduced meet standards and 2) if it would useful introduce a complementary limit. We develop pollution model that...
In view of upcoming more stringent air quality limits and the ambition to align with WHO guidelines, nitrogen dioxide (NO2) pollution from traffic other sources will remain a problem in EU. To assess impact measures emission reductions sectors on NO2-concentrations, an EU-wide high-resolution NO2 source apportionment web-application was developed. The application allows users define scenarios user-friendly way quickly visualize NO2-concentrations at measurement stations cities. user can...
Differential cross sections of the reactions (gamma,pi(0)pi(0)) and (gamma,pi(0)pi(+/-)) have been measured for several nuclei (1H,12C, (nat)Pb) at an incident-photon energy E(gamma)=400-460 MeV tagged-photon facility MAMI-B using TAPS spectrometer. A significant nuclear-mass dependence pipi invariant-mass distribution is found in pi(0)pi(0) channel. This not observed pi(0)pi(+/-) channel consistent with in-medium modification interaction I=J=0 The data are compared to pi-induced...
